TO JOSEPH BELL, Esq., F.R.C.S., FROM WHOSE LIPS I RECEIVED MY FIRST LESSONS IN SURGERY, THIS WORK IS GRATEFULLY DEDICATED BY THE AUTHOR. PREFACE. The rapid advances made in the art of surgery have caused the literature of the science to grow apace. Systems of surgery in many volumes, and text-books of large dimensions, are now deemed neces- sary to cover the field. The practical part of the surgeon's work is, however, almost limited to two questions which he must answer every time his professional advice or help is sought. The first question is, "What is the disease or injury?" The second question is, "What is the proper treatment ? " While I would not for a moment underestimate the importance of a profound study of the principles of surgery, of surgical pathology, or of bacteriology, the present work will be confined to a solution of the two questions just mentioned with the view of putting into the hands of students and practitioners a single volume containing the most practical part of practical surgery. The young practitioner is often embarrassed by not knowing how to make a systematic examination in a case of injury, and he may be placed at a disadvantage by the criticism of excited bystanders. The man who goes about the examination of his patient in a systematic manner, leaving nothing undone and guarding against all contingencies, will not only command the approval of the patient and his friends, but will protect himself against dangerous errors. In the following pages care is taken to make the examination of each disease or injury sys- tematic and comprehensive, and, when possible, directions are laid down as to the methods of examination. The surgery of the eye, the ear, and the skin is now so generally left to the care of specialists in these respective fields that I have thought it best to refer the reader to works exclusively devoted to these studies. While the field of medical diagnosis has been well covered by such excellent works as those of DaCosta, Musser, Vierordt, and others, surgical diagnosis up to the present time is not dealt with in any work that claims to represent the most recent surgical knowledge ; at the same time the profession may almost be said to have stampeded to surgery. This very popularity of surgery, especially among young practitioners, is not free from a serious danger — viz. that in being 8 PREFACE. absorbed with the thouf^ht of the operation that may be required the mind of the surt:^eon dwells too lightly upon the diai^nosis of the dis- ease. I send this work upon its mission with the hope that the reader ma}' be led into the habit of making every examination systematic and exhausti\e, that he may find help in the diagnosis of difficult cases, and that his labors may be thereby lessened and his responsibilities lightened. I take this opportunity of expressing my deep obligations to Drs. Hoegh, Bartlett, Hall, Ferro, and others for valuable suggestions ; to Dr. Florence M. Baier, Dr. Findley, Dr. Mowat, and Dr. C. B. Roberts for long-continued and patient labor in collecting and arranging mate- rials ; and to the many friends who have contributed illustrations. J. W. MACDONALD. Minneapolis, November, 1S97.

CHAPTER I. GENERAL EXAMINATION OF PATIENTS. Introduction. — Year by year the scope of surgery is expanding, and as new territory is added to his domain the surgeon must widen his field of inv^estigation. Until a few years ago he worked within a narrow sphere, and devoted about as little time to the study of diseased conditions in the abdominal, thoracic, and cranial cavities as the modern oculist gives to general medicine. All this is changed. To-day there is no organ of the body beyond the legitimate field of surgery, no cavity whose innermost recesses cannot be explored. It is possible in many surgical diseases and injuries to take in the situation at a glance and instantly to decide upon a plan of treatment ; as, for example, in fractures, dislocations, diseases of joints, and in cer- tain tumors ; but in the broader field of modern surgery every known method of diagnosis must be employed. A systematic and complete examination of his cases is therefore as necessary to the surgeon as to the physician. While the surgeon's case-taking need not, as a rule, be lengthy, it should be systematic and comprehensive. The discovery of one dis- ease or injury should not end the investigation. Every organ and system should pass under review, so that there shall be no possibility of any important point being overlooked. To the student or the young practitioner the formation of a habit of recording his cases in this manner will prove invaluable. By it he trains his powers of observation, collects material from which he can draw conclusions, and, most important of all, avoids errors into which many of his seniors have fallen. It cannot be denied that the wider application of operative pro- cedures increases these dangers. To operate upon a pyosalpinx, and afterward to find that the patient is not benefited owing to the existence of long-standing tuberculosis in the lung, may be a triumph in tech- nique, but it is a blunder in diagnosis. It is sadly disappointing, when a patient submits to clamp and cautery for the relief of hemorrhoids, to find, a few weeks later, that his days are drawing to a close by reason of a carcinomatous liver, which existed but was not thought of at the time of the operation. None but those who have suffered thereby can realize what it is to have treated a fracture of the humerus and to be confronted months afterward with a dislocation at the elbow that was overlooked at the first examination. 2 17 1 8 SURGICAL DIAGNOSIS AND TREATMENT. In the diagnosis of an}- surirical disease or injur}' a decision must be arrived at by two lines of evidence — that derived from the patient or the friends of the patient, and tliat obtained by the surgeon's own objective examination. Information Obtained from the Patient or his Friends. — No matter how clear a case ma}' api)car or how urgent the demand for our assistance, we should not neglect this part of our examina- tion. If called to a case of fracture, do not immediately begin to manipulate the injured limb. While removing your overcoat or gloves it is easy to inquire how the accident happened or in what position the patient was standing or lying when he was injured. A few questions of this character will elicit information which may influ- ence your examination and prove helpful in the diagnosis. For example, a fall upon the outstretched hands is apt to produce Colles's fracture, or upon the shoulder fracture of the clavicle, or upon the knee — with a strong effort on the part of the patient to save himself — fracture of the patella. A history of an injury caused by jumping from a rapidly-moving railway or street car and landing upon the feet excites our suspicion that a fracture of the fibula has been sustained. In every case the following points should be noted under the head- ing of history : Name ; address ; occupation ; age ; sex ; family history ; heredity; habits, etc. ; previous residences; former diseases or injuries and results ; previous operations. 1. Age has an important bearing upon our examination. Sarcoma attacks persons of all ages, but particularly young people. Carcinoma is exceedingly rare before thirty years of age, and common after forty. Tuberculosis of bones and joints is most common in childhood. In- flammation of joints in children is, in nearly all cases, an osteitis, while in adults it not uncommonly begins as a synovitis. Goiter rarely occurs before the ninth year. 2. Heredity. — Our ideas on the question of heredity have undergone considerable change. Formerly it was supposed that a tubercular child must, almost of necessity, be the offspring of tubercular parents. While Baumgarten asserts that it arises more frequently by inheritance than in any other way, the general opinion at present is that, although the bacillus may undoubtedly be transmitted from parent to offspring, the more frequent result of heredity is only a predisposition to the dis- ease. In other words, the child of tubercular parents rarely, if ever, inherits the disease ; he is more likely to acquire it when exposed to the bacillus tuberculosis. Syphilis is a disease in which heredity plays a most important part. The poison can be transmitted through the ova and spermatozoa, so that the characteristic lesions make their appearance before or shortly after birth. It must also be borne in mind that the disease can be thus transmitted long after the power is lost of communicating it by direct contact. Cancer is not now believed to be so markedly hereditary' as was formerly supposed, although its tendency to run m families cannot be denied. It would appear that races and nationality have an influence upon heredity. The whites of the Southern States are more than twice as liable to cancer as the negroes of the same region. The tendency GENERAL EXAMIXATION OF PATIENTS. 1 9 to tuberculosis, on the other hand, is greater in the negro than in the white. Jews are less liable than other whites to cancer and consump- tion, but they are specially liable to diabetes and to certain degenera- tions of the spinal cord in their declining years. In examining for the evidence of heredity the patient should be questioned concerning the health of his parents, brothers, sisters, aunts, and uncles. It occasionally happens that an hereditary disease skips over a generation (atavism) ; hence we must inquire into the histor)' of the grandparents on both sides. 3. Sex. — Apart from diseases peculiar to each sex, there are certain surgical diseases and injuries which, although common to both, show marked preference for the one or the other. Cancer is more common in females, owing to the frequencv with which it attacks the mamma and the uterus. Sarcoma is more frequent in males, from the fact that they are more exposed to blows and other traumatic causes which so often precede sarcomata. The same rule applies to fractures. Goiter is much more frequent in women. 4. The manner of living, habits, occupation, ability to endure fatigue, residence, and, in the case of women, whether married or single, also the number of children, if any, — all of these are important points in evidence upon which we must return a verdict. In the matter of living, the diet, habitation, hygienic surroundings, and the clothing must be taken into account. The appetites, the use of alcohol and tobacco, venereal excesses, and other abuses play an important part. Previous residences must be noted. Natives of Iceland are liable to echinococcus ; residents of tropical countries are liable to abscess of the liver. Certain districts are conducive to goiter, and others to cal- culus of the bladder. Sterility in either sex and miscarriages in females create a suspicion of syphilis, while the puerperal period in itself may be a source of grave disease, as, for instance, extra-uterine pregnane}', in the treatment of which some of the brightest victories of modern surgery have been won. Many cases of sarcoma can be traced back to a fracture or other traumatism. Brain-abscess or blood-clot or epilepsy may manifest its presence weeks or months after the receipt of a blow which caused fracture of the skull. History of the Present Disease or Injury. — The patient or his friends should be required to give the particulars, as far as they can. of the present disease or injur}', the manner in which the first departure from health was felt, and the circumstances under which an accident occurred, the direction and force of a missile, and the position of the body of the injured person at the time of the accident. In cases which are at all likely to come into court these points, although apparently insignificant, should receive close attention, as they may attain great prominence during the trial. Examination of the Patient. — Having noted down the infor- mation which can be obtained from the patient or his friends, the sur- geon next devotes himself to a systematic examination of the case. This is done under two heads: i. General; 2. Special. General Examination. — Under this heading will be comprised 20 SURGICAL DIAGNOSIS AND TREATMENT. (i) the general appearanee of the patient — whether emaciated or well- nourished, well-developed or deformed ; the condition of his mind — whether calm, excited, depressed, delirious, etc. (2) The Position of the Patient. — Much valuable testimony may be obtained by noting the position which the patient assumes while lying in bed. A person in good health or only slightly ill will naturally lie upon his back or in an easy posture on one or other side. In a state of great weakness or when consciousness is impaired the patient is inclined to slide down toward the foot of the bed. Dyspnea induces a person to maintain a sitting posture, while inflammation of the lungs or pleura causes him to lie in the posture which gives most steadiness, usually upon the affected side. In peritonitis the sufferer lies on his back with the limbs drawn up, and cannot even bear the weight of the bed-clothes. In cerebral meningitis the head is drawn backward, bur- rowing, as it were, into the pillow. In localized inflammation of the brain the head is persistently held to one side. When the cerebellum or crura cerebelli are the seat of disease, it is not uncommon to see the whole body drawn sharply to one side, and immediately returning to this position if disturbed. (3) Surface-markings and Changes of Contour. — Under this head will be noted any scars, deformities, changes in the shape of limbs, etc. It will embrace tumors, deformities from old or recent fractures, dislocations, etc. (4) The Condition of the Skin. — {a) Color : Redness may be due to hyperemia, by w^hich is meant an increase of the quantity of blood in the vessels of the part, or to an escape of blood from the vessels (extravasation.) It is a very simple matter to decide which of these conditions is producing the redness. Light pressure will empty the vessels in hyperemia and cause a momentary paleness ; upon extrav- asations or purpura pressure has no effect. Besides paleness or redness, certain modifications of color are deserving of notice. One-sided redness of the face indicates localized vasomotor paralysis and is suggestive of hemicrania. A characteristic sallow hue }\\th shiny appearance is given to the skin in sudden and severe hemorrhage. Prof Syme was in the habit of drawing our attention to the peculiar appearance of the faces of those who suffered repeated loss of blood from hemorrhoids. Cyanosis, or blue-red skin, is due to an accumulation of carbonic acid and a deficiency of oxygen in the capillaries. It arises in connection with disturbed respiration and circulation through the lungs. It may also occur in the greater circulation, and be either general or local according to the extent of obstruction. Cyanosis is seen in the following conditions : spasm of the glottis ; tumors of the larynx ; acute and chronic inflammation of the larynx or trachea ; foreign bodies in the air-passages ; goiter or other tumors which press upon the larynx or trachea ; mediastinal tumors ; bronchitis ; aneur}^'sm of the aorta ; and in any condition which prevents complete expansion of the lungs, such as pleuritic or pericardial effusion, thoracic tumors, and peritonitis w^hen it produces paralysis of the diaphragm, etc. The yellow or jaundiced or icteric skin is of interest to us in the surgery of the liver and gall-bladder. It is not, as a rule, an indication GENERAL EXAMINATION OF PATIENTS. 21 of abscess of the liver ; in fact, its existence may be said to be an argument against the diagnosis of abscess. Obstruction in the hepatic duct or the common bile-duct produces jaundice, while obstruction in the cystic duct does not. One of the most common causes is the presence of gall-stones. It may also be produced by any tumors which press upon the duodenal orifice of the ductus communis choledochus, and especially cancer of the head of the pancreas. A practical point worth remembering is that jaundiced patients bleed more freely during operations than do others. Scars are especially worthy of notice, but in no location are they so important as on the scalp. A scalp wound dressed in the drug-store style, with no regard for asepsis, may heal, to all appearance, in a satis- factory^ manner, but at the same time germs may find their way through the skull along the vessel-channels and lead to cerebral abscess later on. (5) Tevipcratiirc. — High temperature is present in fever, inflamma- tory disease, and some nervous conditions. It is important as indi- cating the absorption of septic material from a wound or pus-cavity, and is a reliable indication for a removal or change of dressings. After operations of any magnitude there is during the first forty-eight hours a rise of temperature known as fermentation or aseptic fever, which may reach 102° F., without exciting any uneasiness. Subnormal temperatures occur temporarily in severe hemorrhages, in chronic diseases of the heart and lungs, and in most chronic wasting diseases. A sudden fall of temperature, accompanied by weakness of the heart and general prostration, is spoken of as collapse. Continued low temperature is rare, but it may be found in abscess, in inflamma- tion of the brain, and in some wasting diseases. In acute alcoholism the temperature has been observed as low as 75"^ F. Local Changes in Temperature. — A local increase in temperature is indicative of inflammation or paralysis of the vasomotor nerves of the part. A lowered temperature is indicative of disturbance of the circu- lation. It is commonly found in venous thrombosis. In paralysis of a nerve the local temperature is usually first increased and afterward diminished. The knowledge gained by the general examination will* point to one or more of the special organs or systems of the body as the seat of the disease. The examination will be continued by making a minute and careful study of the special system or organ to which the symp- toms so far point. Having exhausted that part, the other systems and organs are systematically examined. Our special study, therefore, will comprise — 1. The Vascular System ; 2. The Osseous System ; 3. The Joints ; 4. The Digestive System ; 5. The Genito-urinary System; 6. The Nervous System ; 7. The Respiratory System ; 8. Morbid Growths ; 9. The Female Generative Organs. 22 SURGICAL DIAGNOSIS AND TREATMENT. CHAPTER II. EXAMINATION OF THE VASCULAR SYSTEM. I. THE HEART AND PERICARDIUM. Having removed the patient's clothing so as to expose the chest, the student will find it useful to begin by counting the ribs. The novice may have a little difficulty in distinguishing the first rib. It is covered in its outer half by the clavicle, but near the sternum it lies below the clavicle. Follow the front of the sternum from its notch downward. About \\ inches from the suprasternal notch the fingers will feel a ridge on the bone. This is the junction of the manubrium with the gladiolus, and is exactly opposite to the insertion of the second rib. Having definitely settled the location of either the first or second rib, it is an easy matter to count downward. (Mark with your pencil the third costal cartilage on the right side and the sixth costal cartilage on the left side : these points represent the upper and lower limits of the heart in the healthy chest.) Now mark a point half an inch to the right of the sternum, and another point half an inch to the right of the left nipple, and you have the horizontal limits of the heart. The right auricle lies behind the cartilage of the third rib on the right side, and the left auricle behind the third costal cartilage on the left side. Posteriorly the heart-dulness is found between the fourth and eighth dorsal spines. The left auricle is covered by the pulmonary artery. The right ventricle is partly behind the sternum and partly to the left of it. Behind the right lies the left ventricle, except a small portion at its apex. The pericardium is the fibro-serous sac which contains the heart and the portions of the great vessels which enter into or issue from its base. It is attached above to the deep cervical fascia, and below (which is its widest part) it is in connection with the diaphragm. Two conditions of the heart which call for surgical interference are — overdistention of the ventricles and effusion into the pericardium. Overdistention of the Ventricles. — This occurs in acute pul- monary congestion. When the lung-tissue in a violent onset of acute inflammation becomes engorged with blood and the air-cells are filled with exudation, the blood is forced with difficulty through the pul- monary circulation, the right ventricle becomes overdistended, and, unless relief is obtained, the condition becomes critical. The symp- toms indicating overdistention are — great dyspnea, dulness on percus- sion over a considerable area of one or both lungs, vocal fremitus, and distress over the region of the heart. In the treatment of this dangerous condition the heart may be relieved of a portion of its blood and the distention lessened by tap- ping its cavity. The most convenient method of doing this is to aspi- rate the right auricle. Find the third interspace, and at a point close to the right of the sternum insert the needle. The reasons for select- ing the right auricle are — first, the wall is thinner than that of the ven- tricles ; second, it has a greater antero-posterior diameter ; third, it is least liable to change its position in relation to sun'ounding parts. EXAMINATION OF THE VASCULAR SYSTEM. 23 Operation. — Sterilize the skin and instruments. Use a large-sized aspirating needle attached to the tube of an aspirator, for the force of the circulation is not sufficient to drive the blood through the needle. The needle should be pushed directly backward until it enters the cavity, and the operation should be performed as quickly as possible. It is attended with great danger. I question whether it possesses any advantages over the old method of bloodletting, which is attended with very happy results in just such cases. Effusion into the Pericardium. — Under normal conditions the fluid which lubricates the inner surface of the pericardium is in the form of vapor, thus allowing the heart to beat with the least possible friction or impediment to its movements. In pericardial effusion these favorable conditions are lost, and the laboring heart is compelled to do its work in a pool of watery fluid. In nearly every instance effusion into the pericardium is a sequel of rheumatic fever. The symptoms are dyspnea, great distress in the pre- cordia : as a patient once expressed herself to me, " The heart feels as if it were bursting." The area of dulness is much increased, and may extend as high as the clavicle. The dull area is generally pyriform or quadrilateral in shape, with the base below and extending to both sides of the apex of the heart. The movements of the left chest are im- paired, the veins of the neck are enlarged, and a peculiar wavy motion is felt when the hand is placed over the heart. The apex-beat is felt higher up than in the normal condition, and to the left. By the stetho- scope we find muffling of the heart-sounds and the absence of vocal resonance and fremitus. If we examine the case before the pericardial walls become separated from one another by the fluid, we may find a pericardial friction-sound. This sound is not propagated beyond the pericardium, and is wanting in the regularity of rhythm which charac- terizes the endocardial murmur. Many cases of effusion are slight and have a tendency to end in absorption. In exceptional cases, however, the fluid increases and threatens life. Then we should unhesitatingly resort to the operation of paracentesis of the pericardium. In the left fifth interspace mark with a pencil a spot 2 inches to the left of the left border of the sternum. This, as a rule, is the best point at which to aspirate the pericardium. The reasons for selecting this posi- tion are — (i) it gets at the fluid in the lowest part of the pericardial cavity, thus securing perfect drainage ; and (2) this point is well to the outside of the internal mammary artery. Operation. — Use a good-sized needle and aspirator. Push the needle directly backward until the cavity is reached ; withdraw the trocar quickly, leaving the cannula in position, so as to avoid puncturing the heart-muscle. Draw off the fluid slowly and watch the effect. In the case of a lady upon whom I thus operated the opening was made in the sixth interspace, because the enormous amount of fluid which was present distended the sac much below the usual limits. The heart touched the cannula at every pulsation. The patient fainted several times during the operation. Thirty-two ounces of serum were withdrawn, and a good recovery was the result. When the fluid is found to be purulent the proper treatment is to 24 SURGICAL DIAGNOSIS AND TREATMENT. make an incision and employ drainage. Therefore, while the cannula is still in position and pus is found to escape, use the cannula for a <^uide, dissectini:^ carefully through the tissues until the finger can enter the pericardial cavity. If sufficient room cannot be obtained or if the drainage-tube cannot be kept open, it will be necessary to remove a portion of a rib. The pericardium bears washing out and disinfecting well, and is tolerant of mechanical and chemical irritations. Injuries of the Heart. — Rupture of the heart is, fortunately, rare. It has been known to occur as a result of a thrombus or an embolus causing complete obstruction in one of the branches of the coronary arteries. A sudden rupture of an aneurysm or an abscess into one of the cardiac cavities has produced rupture. It has also been noted as a cause of death in tetanus. The onset of the symptom is so sudden and so fatal as to leave little for us to study in the way of diagnosis. Wounds of the Heart. — The circumstances under which we would expect to find wounds of the heart are — violent compression of the thorax, fracture of the sternum and costal cartilages, with frag- ments driven inward, or wounds from the outside, such as stabs or gunshot injuries. The organ has also been wounded by fishbones or other foreign bodies penetrating it from the esophagus. A wound of the heart does not necessarily occasion death. Strange as it may at first appear, a stab wound penetrating this organ may be followed by little or no hemorrhage. This is due to the peculiar arrangement of the fibers of the cardiac muscles. In examining the heart for wounds we must be guided by the following symptoms : Pain is felt, and it is usually severe, but may be absent owing -to collapse. In most cases there is syncope. If there be escape of blood into the pericardium, we will find the area of cardiac dulness enlarged, owing to the presence of the fluid. At the same time, the heart-sounds will be less distinct, and in certain cases splashing may be heard. A sign of pericardial hemorrhage is dyspnea. Treatment. — The patient should be kept at perfect rest, with the head lowered to avert anemia of the brain, and opium may be given to relieve pain and shock. Unless the hemorrhage from the external wound be copious and of itself threatening life, it is best not to check it, lest the flow take place into the pericardium and cause death by its presence there. II. EXAMINATION OF THE VEINS. The morbid conditions of veins which are interesting from a surgical point of view are — Wounds, TJirovibosis, Phlebitis, Varix or ]^arieose Veins, and Nevus. The examination is made by inspection, and some- times by palpation and auscultation. Wounds of Veins. — When a small vein is wounded it collapses and hemorrhage from it is slight. A wound of a large vein is attended with great danger, owing to the rapidity with which the blood escapes from it. Besides this danger, most serious consequences can arise from septic infection. The symptoms of venous hemorrhage are — a steady flow of dark-colored blood, being in marked contrast to the light-red EXAMINATION OF THE VASCULAR SYSTEM. 25 color and spirting of the blood from an artery ; pressure on the distal side of the vein causes arrest of hemorrhage, while pressure on the proximal side increases it. Treatvioit. — In small veins perfect rest of the part, elevation of the limb, and pressure on the distal side are all that are necessar}'. When large veins are wounded the divided ends should be found and secured with aseptic catgut ligatures. A longitudinal slit in a large vein can sometimes be closed by picking it up with forceps and securing the bleeding point with a ligature, without obstructing the lumen of the vessel. If the longitudinal slit in the vein-wall is too long to be grasped by forceps and ligated, it is possible to close it by a fine con- tinuous silk or catgut suture. It is not necessar)' that a clot should form at the point of ligation. Thrombosis. — In its normal state a vein is a soft, unresisting tube. The superficial vessels are readily seen and felt, while the deeper are beyond observ^ation. When thrombosis takes place all this is changed. The veins become transformed into hard, knotted cords, and some of the deep as well as the superficial can readily be felt beneath the examining fingers. Thrombosis is due to some alteration in the wall of the vessel, to changes in the blood, or to both causes combined. We look for it in parts where the circulation is most feeble, as, for instance, in varicose veins or behind valv^es. In exhausting diseases, such as typhoid fever or advanced phthisis, clots often form very insidiously, without any apparent change in the vessel-walls. Foreign bodies introduced into the lumen of a v^essel produce clots in a short time, and this circumstance is made use of in the treatment of aneurysm. The tendency of venous thrombi is to extend toward the heart, spread- ing from vein to vein. The danger comes when the clot reaches a vessel in which the current is too rapid. A portion of the thrombus is liable to break off, and, being swept into the current of the circulation, sooner or later becomes impacted in a vessel and constitutes an embolus. Phlebitis, or inflammation of v^eins, has the knott}^ cord-like cha- racter just described, but in addition there is acute inflammation of the surrounding cellular tissue (Fig. i). The affected part is very tender to the touch, and at times the skin is reddened. There is usually con- siderable pain and stiffness, particularly on movement, and the discom- fort is increased by allowing the limb to hang down. The limb is stiff, heavy, and unwieldy. When the deep veins of the leg are inflamed, there is usually edema about the ankle due to interference with the return circulation. The treatment includes rest, elevation of the limb, cold, acetate-of- lead lotion, mild cathartics, light diet, and the proper treatment for the diathetic disease which may be the cause, such as gout^ syphilis, or rheumatism. If there is a tendency to the formation of abscess, use warm antiseptic baths, and as soon as practicable get rid of the pus by incision. Varix, or varicose veins, are easily diagnosticated. They are usually found in the lower extremity ; and the vein most commonly involved is the internal saphenous. The vessels are dilated, thick- ened, tortuous, and rise above the level of the skin. Sometimes the varicose condition begins where the veins take their origin from the 26 Si'KGJCAL DIAGNOSIS AND TREATMENT. CiH)illaiy s)'stcm. When such is the case the part shows a fine capilhuy injection with an arborescent appearance. We at other times find the limb presenting a marble-like character, hard and swollen, but not pitting on pressure. This is apt to take on an eczema of the skin, which later forms ulcers — the so-called varicose ulcers. The danger attending varicose veins, and more particularly l'"u;. I. — Phlebitis of the lower extremities in a child. where ulceration is superadded, is the liability to bursting of the veins and inevitable hemorrhage. A varicose vein cannot readily be mistaken for anything else. It is possible, however, that a varix of the internal saphenous may be mistaken for femoral hernia. The point is easily settled. When the patient lies down the varicose tumor disappears ; so does a femoral hernia. Ask the patient to cough or assume the upright position ; both swellings reappear. But press upon the swell- ing while the patient is in the recumbent position, then, still keeping up the pressure, ask him to stand up ; if the swelling is a varix, it will reappear ; if a hernia, it will not. Varicose veins are produced by two conditions acting simultaneously : first, increased local blood-pressure and obstruction of the return cir- culation, and second, a specific pathological condition not yet satis- factorily explained. The commonest causes are tumors in the pelvis, pregnancy, diseases of the heart and lungs, and occupations which require the person to stand long upon his feet. Obstruction or defect- ive development of the vena cava is capable of producing varicose veins of enormous extent, as was shown in a case reported by Dr. Derville. Treatment. — Palliative. — Remove the cause by attention to the bowels and by treatment of the disease which has produced obstruc- tion in the veins. Much benefit can be obtained by wearing an elastic bandage or stocking. Bandages of zinc glue are cheap and very EXAMINATION OF THE VASCULAR SYSTEM. 2/ serviceable. They are applied as follows : A gauze roller bandage is first applied to the leg, and over this a layer of the glue, at a tem- perature sufficient to keep it fluid, is applied with a brush. After a few minutes another layer of bandage, followed by a second coating of glue, completes the dressing. The limb is kept at rest for an hour to allow the bandage to dry. After dissolving the zinc glue the vessel containing it should be left floating in hot water to prevent cooling. Radical measures include the following : Exposure and ligation of the vein, subcutaneous section with compression, multiple subcutaneous ligatures, injections of pure carbolic acid into the tissues about the veins, the use of acupressure needles and twisted sutures, and excision of more or less of the diseased vein. Nevus, telangiectasis, or mother's mark, is a disease affecting both veins and capillaries. Nevi are easily recognized. Their most common seat is on the face, and sometimes on the trunk. In size they vary from a pin's head to an area the size of the hand or even larger. When the nevus is composed of capillaries, the growth is raised slightly above the skin and is of a scarlet or purple color. If veins enter into its formation, it is either in the skin or beneath it. It pulsates and is larger than the capillary nevus, and of a blue color. To this form the name of cavernous angioma is sometimes applied. If one of these growths be cut into or punctured, alarming hemor- rhage is liable to follow. Treatment. — Many operations have been resorted to for the removal of nevus. Ligation and excision are the best. Ligation is best em- ployed by passing a pin under the growth, and then placing a ligature below the pin to constrict the whole mass. Larger nevi require double ligatures, which can best be applied by passing a second ligature under and at right angles to the pin, and tying the nevus in two halves. Excision is very satisfactory when loose skin can be obtained to allow the edges of the wound to come accurately together without puckering or stretching. Injection of coagulating fluids and electrolysis have also been employed, and good results have followed in many cases. It must, however, be borne in mind that this treatment has occasionally led to sudden death from embolism. III. EXAMINATION OF THE ARTERIES. Our inquiries under this head will comprise ivounds of arteries, rupture of arteries, atheroma, inflammation of arteries, and aneurysm. In a wound of any extent the question of hemorrhage is a prom- inent one. It will be necessary to decide what arteries, if any, are divided, and promptly check the flow of blood from them. Blood flowing from a divided artery is bright red and comes in jerks. From a vein it is purple and has a continuous flow or wells up out of the wound. From capillaries bright red blood oozes out more or less freely, and there is no spirting. There are conditions in which the spirting of an artery cannot be seen, as when the divided vessel lies at the bottom of a deep wound and the blood wells up rapidly. The flow is then continuous, but its persistence and profuseness are sufficient evidence that a large vessel 28 SCRGICAL DIAGNOSIS AND TREATMENT. is involved. The position of the wound will indicate the arterial trunk or branch from which the blood flows. The treatment will depend upon the size and position of the vessel, and also upon the amount of blood which is escapint^. In many cases the natural arrest of hemorrhage is sufficient (the contraction of the coats of the vessel within the sheath and the coagulation of the blood in the divided ends of the artery), in others we must assist nature. The readiest temporary method of arresting hemorrhage is by pressure at the bleeding point or upon the artery above it. Never be afraid of a bleeding poi>it ivlien yoii can plaee your finger npon it (not a dirty but an aseptic finger). If you make pressure at the proper spot, vcr}' little force is required, and this force can be easily maintained until permanent control of the bleeding has been secured. Pressure upon the artery above the wound is applied by the fingers, by a tour- niquet, or by an Esmarch bandage. The brachial can be controlled by pressure upon it in the middle of the arm, where it lies in the angle on the inner side of the biceps. The subclavian can be controlled by the thumb pressing the vessel against the first rib. The femoral at Poupart's ligament lies midway between the symphysis pubis and the anterior superior spinous process. It can be compressed most readily by the thumbs of the operator, who stands in such a position that his arms are almost straight. This position is not fatiguing, and can be maintained for half an hour or so without difficulty. The femoral can also be compressed on the inner aspect of the thigh at its entrance to Hunter's canal. The aorta is compressed with difficulty, except in children and emaciated people. It can, in them, be felt just above and a little to the left of the umbilicus. The radial and ulnar can be com- pressed just above the wrist, and the tibial for a short distance above the ankle. Tourniquets are necessary when continued compression is required. The most simple is Esmarch's, which consists of a |-inch rubber tube about 1 8 inches in length, with a hook at each end. It is simply wound around the limb above the wound tight enough to compress the artery. The dangers of Esmarch's bandage are paralysis of nerves (by too long compression) and anemia. Sloughing has been produced, particularly when the tourniquet has been applied for primary hemor- rhage before amputation. It should be kept on as short a time as possible. An emergency tourniquet can be made from a handkerchief tied around the limb and twisted tightly. Having got the bleeding under control, the next question is how to arrest it permanently. The stoppage of the circulation by pressure or the tourniquet has given the blood at the bleeding point time to coagu- late, and if, when the pressure is slowly removed, no blood escapes, the wound may be dressed, leaving the clot in position. When the divided artery can be seen, it should be tied at both ends with catgut or silk ligature. If the wound is not large enough to expose the ves- sel, it must be extended and the bleeding points found and tied. Heat is a valuable means of arresting hemorrhage from a number of small vessels or oozing from a large surface. It is best applied by using water as hot as can be borne by the hand. Cold is also a good hemostatic. It is employed by exposing the EXAMINATION OF THE VASCULAR SYSTEM 29 wound to the air or by ice or ice-water. Its action is upon the muscular coats of the vessels, and is only of value when the bleeding vessels are small. Packing with iodoform gauze is required in niany cases, but except where it is desirable to have the wound heal by the open method, as in operations for the removal of diseased bone, it is seldom employed. Acute Arteritis. — This is a rare disease, and some writers state that it is doubtful if it has ever been diagnosed during life. The cases in which tenderness and redness were observed along the course of an artery having recovered, there was no opportunity to verify the diag- nosis by post-mortem. In a case of symmetrical gangrene which came under my care I was able to trace the radial arteries and the caro- ^^^' J Fig. 2. — Symmetrical gangrene without Raynaud's phenomena (Jonatlian Hutchinson). tids by the tenderness and hard, cord-like feeling, such as is found in phlebitis, and confidently pronounced the condition acute arteritis. The patient, a little girl, died from occlusion of the middle cerebral artery. The post-mortem clearly showed arteritis and an extension of the inflammation from the carotid to the arteries of the brain, which caused her death. The symptoms which are indicative of acute arteritis are — tenderness along the course of the vessel, a hard, cord-like feeling under the fingers when the vessel is pressed upon, and at times obliteration of the artery, followed perhaps by gangrene of the parts to which the artery is distributed. Chronic Arteritis. — This is very important to us from a diag- nostic point of view. Chronic arteritis, or atheroma of the older authors, is the condition which lays the foundation for aneur>^sm. It is chronic inflammation of the internal coat, with fatty degeneration and a tendency to the formation of calcareous deposits. We should look carefully for atheromatous arteries in old people, in those who have 30 SURGICAL DIAGNOSIS AXD TREATMENT. suffered from rheuniatisni, l^right's disease. L^out, or syphilis, and in hard drinkers. We must bear in mind that atheroma affects the large, while s}'philis attacks the smaller, arteries. The disease begins in the inner coat, which becomes opaque and cloudy. The circulation in it is disturbed, and in parts cut off, so that ulceration soon follows. The middle coat does not become involved until late, and the outer coat is affected last of all. It is only when atheroma has produced its evil effects upon the artery that we can diagnosticate its existence during life. These effects are calcification and aneurysm. Following the change in the inner coat is an inflammation in the middle coat, and a deposit of calcareous matter, carbonate of lime, and phosphates. This gives the vessel a firm, hard feeling which has been compared to a pipestem. Such a condition affects the circulation, the vessel losing its elasticity, the flow of blood is impeded, the roughened internal surface increases friction, and, as a consequence, thrombosis and embolism are liable to occur. If the supply of blood is cut off in a marked degree, we have senile gangrene as a result. The arteries are also liable to become elongated and tortuous, as is often seen in the temporals of aged people. What we have to look for then is a hard, pipestem-like condition in the arteries. The vessels may also be tortuous and elongated. The subjects are old people, men much more frequently than women. IV. ANEURYSM. An aneurysm is a tumor containing either fluid or coagulated blood and communicating with the cavity of an artery. Aneurysms are classified as follows : According to their causation they are spoken of as trainnatic and idiopathic. A traumatic aneurysm is one in which the coats of a Fig. 3. — Sacculated aneurysm (Keen and White). healthy artery give way under a sudden injury, forming a tumor, the sac of which is composed of the vessel-wall, the cicatrix, or a clot of blood which closed the wound. Idiopathic aneurysms are those which are produced by disease in the walls of the vessels. The sac is com- EXAMINATION OF THE VASCULAR SYSTEM. 31 posed of one or more of its arterial coats. When the shape is taken as the basis of classification two varieties are recognized : sacculated when the wall at one side of the arter>' is expanded into a pouch (Fig. 3), and fusiform when the coats are uniformly dilated in the whole circumference of the vessel and for a considerable distance in its length (Fig. 4). A dissecting aneurysm (Fig. 5) is a variety by itself Fig. 4. — Tubulated or fusiform aneurysm (Keen and White). Fig. 5. — Plan of a dissecting aneurysm (Holmes). It usually begins in the breaking down of an atheromatous ulcer. The blood makes its way between the arterial coats, stripping them asunder and forming a sort of fistula in the v^essel-wall. After traversing the wall for some distance the stream finds its way back into the vessel or perforates all of the coats, and is extravasated into the surrounding tissues. The terms true and false aneur}^sm are of little practical value. A true aneurysm is one in which all the coats of the artery enter into the formation of the sac. This is only possible when the aneurysm is of small size. A false aneurysm has the inner coat of the arten,^ much altered and thickened, the middle and outer coats have disappeared, and the wall of the sac is formed by the thickened connective tissue of the surrounding parts. In examining for an aneur\'sm our attention should be directed to 32 SCJ^GICAL DIAGNOSIS AXD TREATMENT. the vessels upon w hich tlic greatest strain is thrown. The larger ves- sels, too, are those generally affected. The arch of the aorta, the part where the external iliac becomes the femoral, the parts of the arteries from which branches arise, and the convexities of all the curves are the most common seats of aneurj-sm. The arteries of the brain and those of the lower limbs, particularly the popliteal and the splenic, suffer frequently. Symptoms. — Attention is usually directed to an aneur>'sm by the pain which the patient feels. It is generally severe, and may be described as sharp and lancinating (in that respect resembling carci- noma), or it may be aching or burning like the pain of ulceration. As the pain is due to pressure, the tumor is generally of considerable size before this becomes a marked symptom. At times a nerve — the pop- liteal, for instance — is flattened and stretched over the tumor. The pain Fig. 6. — Aneurysm of the mammary artery (Jepson). in such a case is intense, and is felt along the course of the nerve. If aneur>'sm is located on one of the limbs or in a superficial position, we expect to find a tumor (Fig. 6). The following questions must then be answered : (a) Does the tumor pulsate ? In the first stage of an aneurysm (that is, while the contents are fluid) distinct pulsation can be felt. The pulsation is peculiar ; it is eccentric, expansile, and synchronous with the heart-beat. Place a hand on each side of the tumor, and with each pulsation the palms will be separated from each other. An abscess may have the fluid character of an aneurysm, and, if it happen to lie over the situation of an artery, a pulsation will be communicated to it. In this case the pulsation will be up and down, and not laterally. EXAMINATION OF THE VASCULAR SYSTEM. 33 {b) Has it a bruit ? In an aneurysm, owing to the roughening of the lining of the sac and to the circumstance of the blood rushing into the cavity and out again, a peculiar sound can be heard, not only ov^er the tumor, but also along the artery above and below the sac for a greater or less distance. Sometimes this sound is blowing in character, or it may be rasping like the noise made by a saw. There are malig- nant vascular tumors which have bruits that might be mistaken for aneurysm, but it must be borne in mind that the bruit of an aneurysm is heard along the course of the artery as well, while in the case of malignant tumor the sound is confined to the growth itself {c) Can the size of the tumor be changed by pressure upon the artery ? If we can make pressure upon the artery on the side of an aneurysm nearest the heart, we find that the size of the tumor is dimin- ished, for we cut off the supply-pipe which fills the cavity. If, on the other hand, we press upon the artery on the side farthest from the heart, the tumor is increased, because we obstruct the overflow-pipe and increase the tension in the sac. If aneurysms were always filled with fluid blood, the diagnosis would be comparatively easy. It is only in their first stage that such is the case. As the disease progresses there is always a tendency to the formation of fibrinous layers, which by degrees change the charac- ter of the tumor from a fluid to a more or less solid mass. This is sometimes called the second stage. The effect of this solidity is natu- rally to render the pulsation less distinct, so that in some cases it is entirely lost. It may happen that the fibrin is not deposited evenly in the sac ; in that case we may find pulsation in certain portions of the tumor, but not in others. The tumor being solid, it will not be changed in size by pressure above or below as in the case of an aneurysm in its first stage. Still, as a rule, we have the bruit to rely upon, for it can be heard not only over the sac, but above and below it along the course of the artery. (^) Are there any pressure-effects ? If the veins suffer from pres- sure, we will find edema of the limb below the tumor. This, if long continued, may terminate in ulceration or even gangrene. The effect of constant pressure is to produce atrophy ; hence we have absorp- tion of osseous tissue when bone is pressed upon, as, for instance, the sternum in thoracic aneurysms. Pressure upon the trachea produces difficulty of breathing, and almost a pathognomonic sign of aneurysm of the arch of the aorta is a peculiar, brassy, unfinished cough, due to pressure upon the recurrent laryngeal nerve of the left side. If the esophagus suffers pressure, difficulty of swallowing will result. Hiccough is produced by pressure upon the phrenic nerve, and when the sympathetic nerve is pressed upon we see capillary congestion. Pressure upon the thoracic duct prevents the chyle from entering the blood and may lead to death by starvation. When, in spite of all these inquiries, you are in doubt, an explora- tion with an aseptic hypodermic needle may settle the point. Mistakes to be Guarded Against. — Pulsating tumors which resemble aneurysm are most likely to lead us to a false diagnosis. These are the pulsating encephaloid, soft sarcoma, erectile tumors, and pulsating tumors of bone. The history of the case, the existence of arterial 34 SURGICAL DIAGNOSIS AND TREATMENT. degeneration in other parts of the body, and the characters already- described will, however, as a rule, keep us from falling into error. Treatment of Aneurysm. — Nature in many cases attempts the cure of aneurysm, but seldom succeeds. The process of cure consists in a filling of the aneurysmal sac by the deposit of successive layers of fibrin. Our aim in treatment must be to imitate Nature. If we can cause the circulation in the sac to become slower, either by occlusion of the afferent or efferent vessel or by obliteration of the sac itself, the object will be accomplished. Medical and surgical measures are at our dis- posal. Of the medical methods, Tufnell's is probably the best. It consists in confining the patient to bed in the recumbent position for several months on restricted diet, with the view of reducing the watery elements of the blood and increasing its solid constituents. The diet is restricted to ten ounces of solid and six ounces of fluid nutriment in each twenty-four hours. Opium is given to relieve pain, lactucarium to produce sleep, and compound julap powder to produce watery dis- charges from the bowels. Surgieal Methods. — i. Compression. — This is a very old method, having been used at least 200 years ago ; its early employment, however, was confined to traumatic aneurysm. John Hunter in 1785 tied the femoral artery in Hunter's canal and established a new principle — viz. Fig. 7. — Compression of the femoral artery for popliteal aneurysm (after Esmarch). that it is necessary only partially, and not completely, to intercept the current through the aneurysmal sac. This is the aim of compression, and it can be carried out at some distance from the seat of the disease, as, for instance, over the common femoral when the popliteal is the seat of aneurysm. Compression can be applied by the fingers (relays of assistants keeping up the treatment until the end is attained) or by compressing instruments (Fig. 7) or by flexion of the joints. 2, Rapid cure by tourniquet or by Esmarch's bandage. 3. Ligation. — (c?) Hunter's method : The ligature is applied on the cardiac side of the tumor, one or more branches intervening between the ligature jmd the sac. {li) Anel's method: The same as the EXAMINATION OF THE VASCULAR SYSTEM. 35 preceding, without a branch between the Hgature and the sac. {c) Brasdor's : Ligature on the distal side, without an intervening branch. (d) Wardrop's : The same as the preceding, with an intervening branch. \e) The old operation of Antyllus, in which the artery was tied, both below and above the sac, close to the tumor. This method is now adopted in cases of traumatic aneurysm only. Other methods of treatment are galvano-puncture, the use of coagulating injections, and the introduction of foreign bodies, such as fine wire, into the sac. V. SPECIAL ANEURYSMS. Aneurysm of the Arch of the Aorta. — We cannot here follow the line of investigation laid down for superficial aneurysms. Pressure- symptoms play the most prominent part, and the structures pressed upon will depend upon the position of the aneurysm and upon its size. At the transverse portion of the arch there is less room for expansion than at the other divisions of the vessel, owing to the shallowness of the chest at this part. Consequently, the symptoms of pressure are most marked, and make their appearance earlier, in this form of the disease. In aneurysms of the ascending and descending portions the tumor has more room, and hence the symptoms of pressure are longer delayed. {a) Pain. — From first to last pain is likely to prove the most promi- nent symptom. Some patients will describe a sudden tearing pain as of something " giving way " when in a violent effort the middle coat of the vessel is ruptured, and thus forms the starting-point of the aneurysm. Later, the pain is due to the stretching of fine nerve-filaments in the arte- rial coats or to pressure upon neighboring structures. Anything which increases blood-pressure in the sac will aggravate the pain, and under such conditions the suffering may be excruciating. When the tumor presses against the sternum in front or upon the spinal column behind, a constant boring, dull pain is experienced, and erosion of the bones results. In a small proportion of cases great pressure may be exerted, and yet the patient may never complain of pain. (/;) Bruit. — The characteristic bruit of aortic aneur>^sm is a soft, systolic murmur heard over the tumor and sometimes along both carotid arteries. (r) Pressure-symptoms. — When the transverse or descending portion is the seat of aneurysm, the recurrent laryngeal nerve of the left side, which here winds around the arteiy, suffers from pressure. This pro- duces its effect upon the laryngeal muscles, and the patient suffers from a peculiar cough. The character of this cough is, that it does •not afford any relief It has been aptly described as an " unfinished cough." Hemoptysis is a result of aortic aneurysm under the following conditions: (i) The tumor may press upon the trachea, causing con- gestion and rupture of the vessels which traverse its mucous membrane. (2) The aneurysm may press upon the lung-tissue, cutting off the blood-supply to a portion of the pulmonary substance and causing it to break down. (3) The aneurysm may rupture into the trachea or 36 SURGICAL DIAGNOSIS AND TREATMENT. bronchial tubes. The amount and character of the expectorated blood will afford pretty fair e\'idence of its source. If it comes from the trachea, it appears as a simple stainin<^ of the mucus and the quantity of blood is never large. Coming from a portion of broken-down lung, it has the character of phthisical hemorrhage. When the aneurysm ruptures into the trachea or bronchi, the first appearance of blood may be trifling in amount; but after the lapse of a few hours, when the rupture has had time to enlarge, blood may be forced up in such quantities as to end the patient's life in a few seconds. This is the " bursting of a blood-vessel " which noxelists love to describe. Aneurysm of the Ascending Portion of the Arch. — The .symptoms peculiar to this aneurysm are — {a) The presence of a tumor which can be felt to pulsate to the right of the sternum in the second or third intercostal space. In exceptional cases the tumor may be found to the left of the sternum. At first it is obscure, but later, when by erosion the sternum becomes thinned or even perforated by constant pressure, the thrill and pul- sation may be distinctly felt. Aneurysm of this portion of the aorta is especially dangerous, owing to the anatomical fact that it is covered only by the thin serous layer of the pericardium which allows of the coats becoming rapidly distended and favors rupture into the pericardial sac. In examining the tumor remove all clothmg from the chest and place the patient in a strong light. Slight pulsations are best observed by viewing the chest transversely from the side, the examiner's eye being brought almost on a line with the front of the chest. Aneurysmal pulsation is expansile, not only rising and falling, but expanding later- ally with the heart-beats. To demonstrate this lateral expansion the following simple expedients may be resorted to : {li) Cover the promi- nence with a piece of adhesive plaster which has a slit cut down its middle line. If the pulsation be expansile, the slit will be seen to widen with each pulsation (Fagge and Pye Smith). {8) Fix light paper columns or cones of cotton-wool to opposite points of the tumor : if these cones be found to diverge with each pulsation, the tumor is expansile ; or two single stethoscopes can be used in a sim- ilar manner. By palpation a pulsation or thrill may be felt. If this is observed in the upper part of the sternum, it may be set down as an aneurysm of the ascending or transverse portion of the arch. [b) By auscultation a murmur may be heard over the aorta or aneur- ysmal tumor, but in some cases this murmur is absent. In such cases Sanson! recommends that the patient place within his mouth the small chest-piece of the binaural stethoscope and close his lips over it. In this way a distinct or loud systolic murmur may be heard in the case of a thoracic aneurysm, the " vibrations being communicated to the trachea and thence directly by the air-column to the ears." Pain is usually present, and there is tenderness on pressure over the seat of the aneurysm. (r) The pressure-symptoms are manifested according to the growth of the tumor and its encroachments upon the neighboring structures. As it grows toward the right, the vena cava superior is the first to EXAMINATIOX OF THE VASCULAR SYSTEM. 37 suffer pressure, and as a result there are v^enous engorgement and edema of the upper hmbs. Toward the left it presses upon the pulmonary artery, and produces dilatation in the right side of the heart and pulmonary symptoms resembling phthisis. As the tumor grows upward it presses upon the upper lobe of the right lung or its bronchus. As evidence of this the breathing becomes impaired, and later, when the air is shut out of the lung, there is a dull area on percussion. If the recurrent laryngeal nerve be compressed, there will be the peculiar unfinished cough of aortic aneurysm. It is not uncommon in large aneurysms to find the heart displaced to the left and downward. Pressure upon the inferior vena cava is a very rare symptom. It is manifested by edema of the lower limbs and ascites. Aneurysm of the Transverse Portion of the Arch. — As this portion of the vessel lies behind the trachea, a tumor connected with it is almost sure to interfere with respiration. Hence its most frequent manifestations are a suffocative cough, severe dyspnea, and stridulous breathing. Sometimes the pressure is exerted upon the left bronchus, interfering with the expansion of the left lung and causing a deficient respiratory murmur. The esophagus may be pressed upon, causing difficulty in swallowing and symptoms of stricture. Pressure on the left recurrent laryngeal nerve causes paralysis of the left vocal cord. Sometimes the pupils are unequally dilated, the pupil of the affected side being contracted. This is due to pressure on the branches of the sympathetic nerve. Tracheal tugging is an important sign of aneurysm in this locality. The simplest way of observing this sign is that of Ewart. The ex- aminer stands behind the patient, who is seated in a chair with his head slightly thrown back and steadied against the examiner's chest. The tips of the index fingers are placed beneath the cricoid cartilage, which is gently raised by them. With each beat of the heart a tugging sensation is experienced by the fingers. Surgeon-Major Oliver's method is as follows : The patient is placed in the erect position, directed to close his mouth and raise the chin to the fullest extent. The cricoid cartilage is then grasped between the finger and thumb and gently pressed upward. When a tugging is felt an aneurysm is present. In all cases of suspected aneurysm the voice should be carefully studied. A shrill or crowing voice or one lowered to a whisper or assuming a falsetto character should attract attention. A loud, brassy cough, which has been so well described as the unfinished cough of aneurysm, is especially significant, and is due to pressure upon the left recurrent laryngeal nerve. A laryngoscopic examination should never be omitted, for the vocal cords frequently give evidence of pressure when there are no other respiratory symptoms. The evidence gained by the laryngoscope is thus summarized by Sansom : " On examination the observer may see that in ordinary inspiration there is little if any difference in the position of the two vocal cords ; the left may be a little nearer the median line. The left capitulum Santorini and the left aryteno-epiglottidean fold may be on a somewhat higher level than their fellows on the opposite side. On 38 ■ SURGICAL DIAGNOSIS AND TREATMENT. phonation, the patient being asked to make the sounds softly of " ah " and " ay," the left vocal cord may be seen to remain fixed, while the right advances to the median line, or the right vocal cord may be seen to advance to the middle line and project beyond it. It may encroach so far as to meet the flaccid left cord, the cartilages overlapping when a high note is sounded. Thus, while the whole of the right cord is in view, only a portion, about half or one-third, of the left cord can be seen." The size of the pupils should be carefully studied in the diagnosis of thoracic aneurysm. In common with other intrathoracic growths, aneurysms may cause destruction of .sympathetic nerve-elements by their pressure. Destruction of nerve-elements in the aneurysmal sac is followed by paralysis of the cilio-spinal branches of the sympathetic ; there is a paralysis of the dilator muscle of the iris supplied by the sympathetic, and consequently an unopposed action of the sphincter of the pupil supplied by the third nerve (Sansom). The left pupil is the one usually contracted, and this should be regarded as a strong con- firmatory sign of aneurysm. Examination of the arteries of the upper extremities and neck sometimes affords valuable evidence. The ascend- ing portion of the aortic arch gives off no branches ; the transverse portion gives off the innominate, the left carotid, and the left subclavian. If the aneurysm be confined to the first portion, the pulse-wave in the carotids, brachials, etc. will be unchanged. But let the innominate become involved, and the arteries on the right side will show a dimin- ished pulse-wave, while those on the left remain normal. In palpating the arteries begin with those nearest the aorta — viz. the carotids ; then the brachials ; and lastly the radials. The points to look for are enfeeblement of the pulse-wave in the large arteries and delay in the radial pulse. Aneurysm of the transverse portion of the arcJi involving the innoniinate, or an aneurysm of the innominate itself, produces a feeble pulse-wave in the arteries of the right side and a delayed or obliterated right radial pulse. Aneurysm of the Descending Portion of the Arch. — This portion of the aorta lies near the spinal column, and consequently its pressure-symptoms are associated with this bony structure. Pain is felt near the spine in one or both interscapular regions, and it may run round the chest-wall in the form of intercostal neuralgia. The pain is described as aching or boring, like all pain due to erosion of bone. When the destruction of osseous tissue has advanced far enough to allow of pressure on the spinal cord paralytic symptoms speedily develop. Other pressure-symptoms are — {a) upon the esophagus, causing dysphagia or even stricture ; {li) upon the left bronchus, causing enfeebled respiratory murmur on that side, sometimes bron- chitis, pneumonia, or symptoms resembling phthisis. The aneurysm may rupture into the esophagus, but more frequently into the pleura. It is difficult to differentiate between aneurysm of the arch of the aorta and a similar condition of the innominate, left subclavian, and left carotid. The following points, as given by Wyeth, will aid in arriving at a diagnosis : The tumor in aneurysm of the ascending arch is usually first noticed to the right of the sternum, between the clavicle and the third rib. The pressure-symptoms do not affect the voice until the EXAMINATION OF THE VASCULAR SYSTEM. 39 tumor is recognizable in the right side of the root of the neck, where it involves the right recurrent laryngeal nerve. Respiration may be inter- fered with or cough produced by compression of the right bronchus. This condition will be recognized by the hissing rales distributed over the area of the right lung. Aneurysm of the transverse arch is usually first recognized to the left of the sternum at about the same plane as for the ascending segment. Laryngoscopical examination will demon- strate that whatever of muscular paresis exists is confined to the left vocal bands. If the tumor rises into the neck, its appearance will have been preceded by pressure-symptoms of longer duration and greater severity than in either innominate, carotid, or subclavian aneurysm. Innominate aneurysm usually appears at the upper margin of the sternum in the space between the two tendons of origin of the right sterno-mastoid muscle or in the interclavicular notch. The disturbance of the circulation through this vessel so affected may be recognized by the difference in the force and character of the pulse-wave in the radial arteries of the two arms. In aortic aneurysm, when the innominate is not compressed by the tumor, the pulse-wave is the same in both arms. It must, however, be borne in mind that in sacculated aneurysms, springing, as they not infrequently do, from the arch in immediate proximity to the orifice of the innominate, and rising to the root of the neck in front of, or behind this artery, a positiv'C diagnosis is scarcely possible. The pressure on the innominate may retard or weaken the right radial pulse. Aneur)^sm of the left carotid artery first appears at the left sterno- clavicular articulation in the line of this vessel. The murmur is trans- mitted toward the distribution of the carotid, and is not heard in its fellow opposite. When the left subclavian is involved, the swelling usually appears to the left of the sterno-mastoid muscle, and the pulse in the left radial differs from that of the right. Treatment of Aortic Aneurysm. — The treatment of aortic aneur^'sm may be considered under the following heads : Rest is the first consideration, and should be resorted to at the earliest possible period. It lessens the tendency to rupture of the aneur>^sm, and it helps to arrest the growth of the sac by diminishing the blood-pressure. A person in health having a pulse-rate of 70 while in the sitting posture will have a pulse of 78 when standing. The difference between the recumbent and erect posture in a person suffering from aortic disease is still greater ; hence a saving of many pulsations may be effected in the twenty-four hours by keeping the patient at rest. Diet. — Tufnell's method of feeding is the best yet adopted. It con- sists in giving ten ounces of solids and eight ounces of liquids in each twenty-four hours. The diet list for such a patient is as follows : breakfast, two ounces of white bread and butter and two ounces of milk or cream ; dinner, three ounces of meat and three ounces of potatoes or bread, and four ounces of water or claret ; supper, two ounces of bread and butter and two ounces of milk or tea. Mcdicijie. — lodid of potassium has proved itself the best drug, and was first advocated by Balfour in Great Britain and Bouillaud in 40 SURGICAL DIAGNOSIS AND TREATMENT. r^rancc. To commence the treatment, five grains should be taken three times a day ; at the end of a week this should be increased to ten grains, and later to fifteen or twenty grains thrice a day. These doses can be keep up for weeks, months, or even years. When there is excessive heart-action or palpitation, aconite in one- or two-minim doses given every hour affords great relief Pain is controlled by hypodermic injections of morphine. Anesthesia is recommended by Sansom, not only as indispensable during the operative procedures about to be described, but as a valuable therapeutic measure previous to, and perhaps in substitution of, surgical interference. The cases most suitable for treatment by anesthesia are those in which there is severe pain, either continuous or paroxysmal. Chloroform is given daily for several days, and the patient is kept under its influence for several hours each time. The effect of prolonged anesthesia is to allow time for coagulation of the blood within the sac. Operative Measures. — Distal ligature is attended with a fair degree of success. When the transverse portion of the arch or the innominate or the portion of the aorta close to the innominata is the seat of aneur- ysm, the right carotid should be tied or the right carotid and right subclavian. Ligation of the left carotid has also been practised, and with good results in several cases. The operation is less dangerous than the tying of both vessels on the right side, collateral circulation being carried on more easily. Galvano-puncture is attended with considerable danger, but, as the cases for which it is demanded are otherwise hopeless, the patient may justly claim the chance which it holds out. Of 114 cases in which it has been employed, 68 were improved (Petit, cited by Sansom). It is employed as follows : Having taken all the precautions required for making the operation antiseptic, two needles are pushed through the skin covering the tumor and into the sac. The needles are then con- nected with the poles of the battery and a current of from twent>' to thirty milliamperes turned on. The positive needle is then moved about in the sac so as to touch the wall of the aneur>'sm at different points. This is kept up for ten to twenty minutes, after which the current is gradually reduced and the needles disconnected. The positive needle is first to be withdrawn. Should it be covered with fibrin so as to prevent its withdrawal, the current must be reapplied in the opposite direction until the needle is loosened. The object of this operation is to cause coagulation of the contents of the sac. The risks of the operation are — {a) The blood may coagulate in the center of the sac, the clot remaining soft, and finally breaking up in the blood-current, {b) Blood may spurt freely from the punctures made by the needles, and death may follow from inflammation of the sac. {c) Small coagula may be carried off in the circulation. Introduetio7i of Foreign Substances into the Sac. — W'ire has been passed into the sac through a fine cannula, and the cavity filled with coils with the object of inducing coagulation. This measure has been so unsatisfactory that it is now practically abandoned. Never- theless, one or two cases have been cured in this manner. Macewen introduces metallic needles into the sac, leaving them in position for twenty-four hours, and then withdrawing them. EXAMIXATION OF THE VASCULAR SYSTEM. 4 1 Aneurysm of the Carotid. — The common carotid is liable to aneun'sm at any part of its course, but more particularly at its bifur- cation. This arter}^ departs from the rule that aneurysm is more com- mon in men than women, for in this case the sexes suffer equally. Some authors speak of two varieties, the high and the low, the low being confined almost entirely to the right side. A tumor along the course of the common carotid with expansile pulsation and bruit is very likely to be an aneurysm. Further evidence would be the following pressure-symptoms : dyspnea, spasmodic cough, and hoarseness from pressure upon the trachea, the recurrent laryngeal, or the larynx ; difficulty of swallowing from pressure upon the esoph- agus or upon the pharynx in the case of the internal carotid ; neuralgia from pressure of the cervical nen^es ; contraction of the pupils from pressure upon the sympathetic ; edema from pressure upon the internal jugular or, in rare cases, upon the left subclavian. In most cases the diagnosis is very easy, but when low down in the root of the neck a positive opinion is difficult to arrive at, and in some cases a clear diagnosis is impossible. It is impossible at times to say that aneurysm of the carotid exists alone, for a similar condition of the subclavian, the innominate, or the arch of the aorta may strongly simu- late it. The rules for differentiating already given may aid in coming to a decision. Cysts lying upon the common carotid should not lead any one into error, for the character of the pulsation is not expansile. Enlarged lymphatic glands are not likely to cause doubt, for these occur in groups and are lobulated. A rare condition which might give rise to a disastrous error is aneurysm of the internal carotid pressing upon the tonsil and simulating an abscess. Abscess of the tonsil is an acute disease, which, as a rule, runs its entire course in about nine days, while aneurysm is a chronic affection, and must have existed for many weeks before enlargement of the tonsil is produced. Besides this, tonsillitis is attended with high fever and other symptoms characteris'tic of local inflammation. TrcatJiu'iit. — If there is sufficient room, the vessel should be ligated on the proximal side of the aneurysm, otherwise on the distal side. Vertebral Aneurysm. — Aneurj^sm of the vertebral arter)^ is, as a rule, of traumatic origin. It may be confounded with aneurysm of the carotid. The point may readily be settled by pressing upon the com- mon carotid. If the artery be pressed firmly backward at its bifurcation, the circulation in the sac will be diminished if in a branch of the carotid, but unaffected if the vertebral is the divte.ry involved. It cannot be too strongly impressed upon the examiner that rough handling of an aneur^^sm is to be avoided, owing to the danger of detaching a clot which might be carried off in the circulation to form an embolus. That caution is particularly applicable to aneurysms in this locality, for a detached clot might readily be carried to the brain and produce disastrous consequences. Orbital or Ophthalmic Aneurysm. — The ophthalmic artei-)^ may be the seat of aneurysm, either in the orbital cavity or within the cranium. Many of the cases of orbital aneurysm are not true dilatations of the artery, but pulsating tumors, angeiomata, or arterio- venous aneurysms. The diagnosis is readil)' settled b}' pressure upon 42 SURGICAL DIAGNOSIS AXD TREATMENT. the common carotid. If pulsation ceases, it points to the treatment, which is ligation of the carotid — an operation whicii has been attended with about 75 per cent, of cures. Subclavian Aneurysm. — The artery is divided into three parts : the first part on the rit^iit side ascends obliquely outward from the origin of the vessel to the inner border of the scalenus anticus muscle. On the left side it ascends vertically to gain the inner border of that muscle (Gray). The second part passes outward behind the scalenus anticus. The third part passes from the outer margin of that muscle beneath the clavicle to the lower border of the first rib, where it becomes the axillary. Landmarks. — Near the outer border of the sterno-mastoid, and about one inch above the clavicle, the pulsations of the artery can be felt. Behind it is the first rib, against which the vessel can be readily compressed. Stand behind the patient's shoulder and make compression with the thumb in the downward direction and a little inward. The third portion of the artery is the part most frequently involved. Next in order comes the first part, while the middle portion, owing to its having the firm, resisting scaleni muscles in front of it, is least likely to be the seat of aneurysm. The right side is much more frequently affected than the left. Generally speaking, the first indication of aneurysm of the subclavian is a tumor felt behind the clavicle and to the outer side or behind the sterno-mastoid muscle. In its full devel- opment it forms an elongated tumor behind and above the clavicle, and has a tendency to rupture before attaining a large size. Errors in diagnosis are apt to occur — first, by mistaking a glandular or other tumor for an aneurysm, just as in the case of the carotid. The absence of expansile pulsation and the fluidity of the tumor should remove all doubt. Second, it may be difficult to determine from what vessel the aneurysm springs. The history will help us. An aortic aneurysm produces pressure-symptoms, and often causes death long before it reaches the position of the subclavian. On the right side, therefore, the question is easily settled. On the left side aneurysm of the subclavian is rare, but the diagnosis is more difficult. Attention to the following points may be of service : A tumor in the neck appears early in the case of subclavian aneurysm, late in the case of an aortic. The return circulation in the arm is interfered with in the case of the subclavian ; not at all or late when the aorta is affected. The radial pulse is changed in rhythm and volume on the affected side in sub- clavian aneurysm, while if the second or third portion of the arch of the aorta is the seat, there is no change in the radial pulse until the branches are affected. Treatment. — Tufnell's treatment should first be tried. Compression on the proximal side of the aneurysm is only possible when the third portion is involved. Ligation of the artery is most successful when applied to the distal side. As a last resort the artery may be tied at the proximal side of the aneurysm and the arm amputated at the shoulder-joint. Axillary Aneurysm. — The right side is much more frequently affected than the left, and in most cases the aneurysm can be traced to an injury. The growth of the tumor is rapid, and may be found pro- EXAMINATION OF THE VASCULAR SYSTEM. 43 jecting downward into the axilla, inward and against the thorax, in some cases causing absorption of the ribs from pressure; or upward under the clavicle, in which case the shoulder is elevated. The move- ments of the arm are interfered with, the head is drawn to the same side, and the elbow is abducted. The more prominent pressure-symp- toms are pain running down the arm from the brachial plexus, and edema from interference with the return circulation through the axillary vein. Trcatinoit. — Compression, either digital or instrumental, to the third portion of the artery should first be given a thorough trial. Failing in this, the vessel should be ligated at this point. Aneurysm of arteries below the axillar}' are rare, and usually the result of injury. They present no special difficulty in diagnosis, and can be recognized by the general principles already laid down. Aneurysm of the Abdominal Aorta. — Any part of the artery may be the seat of aneurysm, but the most common position is near the diaphragm. The whole arter\' may be expanded in the form of a large fusiform aneurysm, or the tumor may be of the dissecting or sacculated variety. One or other of the branches of the aorta may be involved or even obliterated by pressure. History. — There is generally a history of injury or severe muscular effort or continued laborious employment. If the aneurysm is idio- pathic, the disease of the vessel is likely to be extensive. In the early period the symptoms are obscure. Pain varies in character, sometimes continuous, sometimes parox- ysmal — in some cases running along the course of the nerves, in others confined to one fixed position. When pain is continuous, it is due to erosion of the spinal column, and is characterized as gnawing or boring, referred to the back, sometimes at a fixed point over one of the verte- brje. This pain is relieved when the patient assumes the recumbent position with the face downward : it is aggravated by localized pressure and by such movements as stamping or riding in a jolting vehicle. An advanced stage of erosion may result in paralysis due to involvement of the spinal cord. Pulsation. — The pulsation is expansile and attended with a bruit, which can be heard not only in front, but behind. The most distinct pulsation is found a little to the left of the middle line and near the ensiform cartilage. This is especially the case when the aneurysmal sac bulges forward. Pulsation, on the other hand, may be absent if the sac points laterally and posteriorly. If the tumor is high up and shielded by the pillars of the diaphragm, it may attain an enormous size without showing signs of pulsation. In such cases the diagnosis must rest upon the subjective symptoms, especially pain. In rare cases a heaving pulsation is apparent near the dorsal and lumbar vertebrae and the adjoining ribs and interco.stal spaces. Prcssnrc-syuiptouis. — Pressure upward against the diaphragm pro- duces dyspnea ; against the stomach and intestines, dyspepsia, colic, or other disorders of digestion ; against the bile-duct, jaundice. One or other of the abdominal organs, such as the liver or kidneys, may be pushed aside. The tumor does not move with the diaphragrti. Although it generally increases in size in the direction of least resistance, a small 44 SCA'G/C.U. jn.iGXOS/S AND TKEAIMEAV. proportion of cases press clirectl)' upon the spinal column, producing erosion of the bones. lirrors to l)c Avoided. — In thin persons the abdominal aorta is readily felt, and a strong pulsation, with a slight amount of expansion at each diastolic movement, can be readily mistaken for aneurysm. Abdominal pulsation, according to Douglas Powell, is due to vasomotor disturb- ance, and may be induced by hemic, emotional, malarial, and reflex causes. The advice of Sir William Jenner is worth bearing in mind : " Instead of being your first, it should be your last idea that abdom- inal pulsation is due to aneurysm." Aneurysm of the Branches of the Abdominal Aorta. — An>- of the branches may be the seat of aneurysm, but the vessels most commonly affected are the celiac axis and the superior mesenteric. In our decision we must be guided by the general character of aneurysm Fig. 8. — Aneurysm of the celiac axis. and the position of the tumor. When the celiac axis is the seat of the disease the tumor projects forward toward the right side under the liver. In the only case of this form of aneurysm that has come under my observation the tumor was on the left side near the middle line. The post-mortem revealed an aneurysm of the celiac axis about 4 inches in diameter (Fig. 8). When the superior mesenteric is involved the tumor is more movable, except when the origin of the vessel is the part dilated. Iliac Aneurysm. — The common iliac or the internal or external branch may be the seat of aneurysm. The tumor is soft, circum- EXAMINATION OF THE VASCULAR SYSTEM. 45 scribed, expansile, and the bruit can be heard along the course of the artery. Pain is not severe, except when the genito-crural or obturator nerve is involved. Owing to the room for expansion, the pressure- symptoms are not marked until the tumor has attained a large size. In a few cases the veins have been obstructed, resulting in edema and gangrene. Additional evidence can sometimes be gained by an exami- nation per vaginam or rectum. The errors in diagnosis to be guarded against are — i. Abscess in the neighborhood of Poupart's ligament. The error is more liable to occur from the fact that an aneurysm may contain pouches, which, lying beneath the ligament, may fluctuate, but do not pulsate. Lancing bv Dr. Rrown). a supposed abscess under these circumstances would be a serious blunder. 2. Pulsating sarcomata and tumors growing from the bones are difficult to distinguish from aneurysm. Our reliance must be placed upon the position of the tumor, its connection with bone, the want of the characteristic bruit, and the general characters already described. Treatmoit. — In the common iliac. Tufnell's treatment should be tried. If this fail, proximal, with or without distal, pressure may be successful. In the external iliac the same treatment should be em- ployed, failing which the external or common iliac may be ligated. Distal ligature in this locality has never been successful. 46 SURGICAL DIAGNOSIS AND IREATMENT. Femoral Aneurysm. — Landmarks. — At a point midway between the anterior superior sj)ine of the ilium and the symphysis pubis the arter\- ean be feU pulsatin^^. From this point to the spur-hke tubercle for the insertion of the adductor magnus on the inner side of the knee draw a straight line. The femoral artery lies under the upper two- thirds of this line. The profunda rises about I ,V or 2 inches below the ligament. The common, sujjerficial, or deep femoral may be the seat of aneurysm. As regards the common trunk there is little trouble in diagnosis, as the usual signs are well marked (Fig. 9). It is, however, difficult to decide whether the dilatation is situated upon the super- ficial or deep branch. If the pulsation of the superficial can be felt overlying the deep vessel, the point is settled, but this is not always possible. It is well to remember that the superficial is the branch most commonly affected. Treatment. — i. Proximal pressure; 2. Ligation If in Hunter's canal, ligate the artery higher up ; if in Scarpa's triangle or if the profunda is involved, either the common femoral or the external iliac may be tied. Popliteal Aneurysm. — Landmarks. — A line drawn down the middle of the ham will overlie the vessel. The guide to it is the outer border of the semi-membranosus muscle, under whose fleshy belly the artery lies. Pressure upon the vessels should be made against the bone nearer to the inner than the outer hamstring, and considerable force is required to obstruct the flow of blood. Next to the aorta, this arteiy is the most common seat of aneurysm. This may be accounted for on the following grounds : i. The artery is more subject to atheroma. 2. It is but slightly supported by sur- rounding parts. 3. It is readily overstretched by undue extension of the knee and compressed by forced flexion. 4. Embolus is liable to lodge in it from the fact that the vessel breaks up into a number of branches. Cases are not infrequent in which both limbs are affected either simultaneously or consecutively. Both fusiform and sacculated tumors occur-, but the latter is more common. The progress of a popliteal aneurysm is usually rapid, except when the dilatation takes place on the front of the artery and presses against the bone, in which event its growth is slow. The patient who is the subject of a popliteal aneurysm has probably complained of supposed rheumatic pain in his knee, with stiffness of the joint and weakness of the limb. Next a swelling is observed, and later it is discovered that the swelling pulsates. In many cases the disease develops suddenly as the result of some violent exertion. The sac is easily emptied by pressure on the artery above the tumor, and distended by compression on the distal portion of the vessel. The bruit is distinct and runs down the course of the arter>^ If the sac becomes filled with clots, these signs may be wanting, but there will still be the history of a time when pulsation was distinctly felt, and in a certain proportion of cases pulsation ceases to return after a greater or less time. Synovitis is a complication likely to arise when the sac presses forward against the joint. This aggravates the pain and impairs movement. EXAMINATION OF THE VASCULAR SYSTEM. 47 Treatment. — Flexion, proximal compression, elastic bandage, or ligature. Traumatic Aneurysm. — In the forms of aneurysm already de- scribed the starting-point is a diseased condition or an overstretching and partial rupture of the arterial coats. Traumatic aneurysm is the result of a direct injury, a stab, or complete rupture of the artery, with escape of its contained blood into the surrounding tissues ; that is, the formation of an arterial hematoma. At first the blood may escape freely from the vessel, but as it infiltrates the tissues the pressure increases until it cheeks the hemorrhage. The symptoms denoting traumatic aneurysm are the formation of a pulsating, painful tumor immediately following a wound or injury of an artery (Fig. 10). The bruit is generally distinct, and the pulsation in the artery beyond the tumor is usually lost. Tension is a marked symptom, and the skin shows a red, inflammatory character, with increased temperature. Should pyogenic organisms gain entrance, the formation of an abscess will result, which on being opened is attended with dangerous hemorrhage. Besides this danger, sloughing and even gangrene may occur when an important artery is the seat of lesion or when tension is not relieved. Fig. 10. — Diffuse traumatic aneurysm of the brachial artery (White). Errors in diagnosis may be made by mistaking an abscess for aneurysm. Although the resemblance may be close, we must remem- ber that an abscess cannot form in an artery as an immediate result of injury. The stages of inflammation and suppuration must take several days, while traumatic aneurysm occurs in a few hours. In cases of doubt the introduction of an exploring needle will settle the point. Treatment. — Apply an Esmarch bandage on the proximal side of the aneurysm and cut down upon the tumor, turn out the clots, divide the vessel completely at the injured points, and ligate both ends. Dress the wound antiseptically. If the aneurysm is so situated that an elastic bandage cannot be applied, dissect down upon the tumor, make an opening large enough to admit the finger, and search for the bleed- ing point. The flow of warm blood will act as a guide to the finger. When the opening is found press upon it to stop further hemorrhage, enlarge the wound, and turn out the clots. Now by means of an aneurysm needle pass a catgut ligature around the artery above, and another below the point compressed by the finger. In gunshot wounds especially, when the aneurysm is on one of the arteries of an extremity or when a large artery is involved near the trunk, and the blood-supply to the limb is evidently cut off, rendering gangrene inevitable, amputa- tion is the proper treatment. 48 SrRG/C.IL DLU;X0S/S .I.V/) JRKATMKNr. Other blood-tumors bcann<; a close relation to aneurysm, but not falling strictly within the definition, are certain tumors. Cirsoid iriii'iirvsin is a tumor consisting of a number of small-sized arteries elongated and dilated. The tumor is soft, bluish in color, irregular in shape, and pulsating. It is always superficial, and is readily distinguished from true aneurysm. Arterial varix is to an artery what a varicose condition is to a vein. It is a single small artery dilated and elongated. Anairysnial varix is a communication between an artery and a \ein without the intervention of a sac. We do not see it often now-a-days, but in the good old days when bleeding was universal the condition was quite common. If, instead of opening the vein alone, an unskilful operator incised both artery and vein, and then, as was the custom, applied a firm compress to arrest hemorrhage, an aneurysmal varix was a common result. It occurs in this wise : By inflammatory action the artery and the vein become adherent, leaving the wound in each still permeable, allowing arterial blood to pass through at every pulsation of the heart. The force of this current of arterial blood against the weak wall of the vein causes dilatation, but no sac is formed. A peculiar bruit attends this condition. Prof Spence of Edinburgh was in the habit of comparing it to the sound of a blue-bottle fly in a paper bag. Valentine Mott compared it to the purring of a kitten. Besides the bend of the elbow, aneurysmal varix may affect the carotid and internal jugular and the common femoral vessels. Treatment. — Many cases require no treatment, except an elastic bandage to prevent further enlargement. In cases attended with pain and disturbance of the circulation pressure at three points may be employed — viz. on the artery above, on the vein below, and over the aneurysmal varix. This failing, operate as follows : Expose the varix by dissection, place a ligature above and below the opening in both artery and vein, and cut out the aneurysm. Varicose Aneurysm. — It is always puzzling to the student to distinguish between aneuiysmal varix and varicose aneurysm. They are alike in this respect, that in both conditions there is a communication between an artery and a vein. Both have a like cause — that is to say, a wound of the artery and the vein. The results of that wound, how- ever, are different. In aneurysmal varix the walls of both vessels become adherent and there is no sac. There is really no aneurj^sm, and you will notice that it is not called an aneurysm. It is the adjective " aneurysmal " that is employed. In varicose aneurysm a real sac is formed by the outpouring of blood between the artery and the vein, while the opening in both vessels remains as in the former case. It is a real aneur>'sm, and is so designated, for the noun " aneurysm " is used. Treatment. — The most satisfactory is that employed by Spence, who cut down upon the artery above the sac, and also below it, ligating the artery at each position. This operation shuts off the current from the sac and allows coagulation to take place. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 49 CHAPTER III. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. Ix examining the osseous system we shall consider fractures, dis- locations, inflammations of bone, tumors of bone, and deformities. I. FRACTURES. As a rule, the diagnosis of fractures is not difficult. In many cases the diagnosis is made by the patient or his friends before the arrival of the surgeon. This is usually the case in fracture of the femur, the humerus, or both bones of the forearm or of the leg. There are some fractures, however, which require considerable skill and judgment to decide upon their nature, owing to the obscurity of the symptoms, the amount of swelling, and the position of the bone. As fractures come into the class of cases which we may designate as emergencies, I shall take this opportunity to say a few words upon emergency cases in general. An accident, as a rule, creates a panic. Everybody " loses his head," and the young surgeon is often perplexed and embarrassed. When a messenger summons you to such a case do not allow his haste to disconcert you. Compel him to take time to tell you the three following things : i. The correct name and address of the injured person, which you must carefully write down ; 2. Whether or not he has been removed from the scene of the accident ; 3. W^hat the nature of the injury is. Sometimes the messenger will tell you he ran off in such a hurry that he did not wait to ask what had happened. As a rule, howev^er, he can giv-e some idea of the condition of things. He can tell whether the injured person is bleeding and whether he is con- scious. If he can state how and under what circumstances the accident occurred, the surgeon can form a fairly correct idea as to the proba- bility of fracture or dislocation. These inquiries need occupy but a few moments, and frequently sav'e much time and annoyance. A business-like young surgeon will always have his satchel well stocked and ready for emergencies. He should have in it at least the following : Needles, prepared catgut, corrosive-sublimate tablets, iodo- form and sublimate gauze, absorbent cotton, a few bandages, two bistouries, six hemostatic forceps, a pair of scissors, a male catheter, a hypodermic syringe, a bottle of chloroform, Esmarch's inhaler, a 4 per cent, solution of cocain, a half ounce of collodion, a razor, a nail-brush, and two plaster-of-Paris bandages. When the patient has not been removed from the scene of the accident before the arrival of the surgeon, a brief examination must be made to ascertain the character of the injuries. If hemorrhage be profuse and a vessel of considerable size be wounded, a tourniquet may be applied temporarily until the patient is removed to his home or to a hospital. If a limb be fractured or severely lacerated, a tem- porary splint must be applied. The patient may complain of cold, and no amount of clothing heaped upon him can make him comfortable. 50 SURGICAL DIAGNOSIS AND TREATMENT. A hypodermic of morphine acts speedily and effectually, allaying pain, causing the patient to feel a sensation of warmth and comfort. It is also an excellent remedy for shock — better than alcoholic stimulants. If the patient be unconscious, place him on his back with the head slightly raised, care being taken to give the lungs free play by unbutton- ing the clothing over the chest and removing the neckwear. The utmost care should be observed in moving the injured person. In a fracture of the lower extremity the fragments are liable to lacerate the tissues or may even perforate the skin, thus converting a simple into a compound fracture. One attendant should support the fractured limb, and before transporting the patient on a stretcher the two limbs should be tied together to prevent the injured member from rolling outward by its own weight, or a blanket or coat may be rolled up and placed against the outside of the limb as a support. Arrived at the sick-room, the surgeon will find it to his advantage to select two or, if necessary, three of the most intelligent of the bystanders, while he quietly but firmly asks all the rest to retire. This will relieve him of a crowd of critical observers, while the favored few who are asked to remain, feeling that a compliment has been paid them, fall into line as willing helpers. Fig. II. — Partial or green-stick frac- ture of the radius (Stimson). Fig. 12. — Transverse fracture of the femur (Gurlt). In removing clothing the sound arm should be slipped out of the sleev^e first, after which the injured arm can be liberated without much trouble. In cases where much pain is suffered the scissors can be used to rip up seams and remove the garments with the least disturbance possible. Classification of Fractures. — Fractures are classified as fol- lows : I. Incoinplctc Fractures. — This class comprises fissures of flat bones, such as those of the cranium, in which the line of fracture does not extend completely across the bone nor through its entire thickness. It lAy CRIES AND DISEASES OF THE OSSEOUS SYSTEM. 51 can also occur in long bones when the continuity has not been entirely lost, as in the so-called "green-stick" fracture (Fig. 11). Then there may be a simple depression of a part of a bone as when a blow is received upon the head which bends a portion of the bone inward. The separation of a splinter of bone or of an apophysis is sometimes spoken of as an incomplete fracture. We often hear of a bone being simply splintered, but, as rule, such a diagnosis is evidence of doubt Fig. 13. — Oblique fracture of the clavicle (Stimsdn). in the mind of the surgeon as to the existence of fracture. When a bone is splintered, it is usually by direct violence, as in the case of a sword or bullet wound. The forcible contraction of a muscle may splinter a bone at the point of insertion of the muscle. 2. Complete Fractures. — In this variety there is a complete breach of continuity of the bone. According to the direction of the line of fracture it is spoken of as transverse (Fig. 12), oblique (Fig. 13), longi- FlG. 14. — Intercondyloid fracture of the humerus (Stimson). Fig. 15. — Comminuted perforating gunshot fracture of the head of the humerus (Army Med. Mus.). tudinal, toothed, V-shaped or T-shaped. When the seat of fracture is taken into consideration, we speak of fracture of the neck, shaft, con- dyle, etc. When in the vicinity of a joint the fracture is spoken of as intracapsular (within the capsular ligament), extracapsular (without the capsule), or when extending into the joint as intra-articular. The most common example of this is in longitudinal fracture of the lower end of the humerus, when the fracture extends into the elbow-joint 52 SURGICAL DIAGNOSIS AND TREATMENT. (Fig. 14). When a bone is broken into a number of fragments it is said to be comminuted (Fig. 15). 3. Couipouud fractures, in which the broken bone communicates with the exterior through a wound of the soft parts. Diagnosis of Fractures in General. — In taking the history of the case — which in the first instance may be oral — care should be taken to note the nature and direction of the force which caused the injury. Fractures occur by — i. Direct violence, as when a falling body strikes the clavicle, fracturing the bone. 2. Indirect violence, as when a person falls, the shoulder first striking the ground and thus fracturing the clavicle. 3. Contre-coup, as when a blow upon the head causes fracture, not at the point of contact, but at the opposite point of the skull. 4. Muscular action, as when the patella is broken by powerful contraction of the quadriceps. A violent effort in throw- ing a ball has broken the humerus, and a desperate kick at a dog, which all too nimbly gets out of harm's way, has been known to frac- ture the femur. Forcibly throwing the head backward has broken the neck. The ribs have been broken by violent coughing, and the ster- num during the pains of labor. The coracoid process has been wrenched off by the contractions of the coraco-brachialis, pectoralis minor, and short head of the biceps ; so has the posterior part of the calcaneum by the action of the muscles of the calf The evidences necessary to prove the existence of a fracture are — I. Deformity; 2. Abnormal mobility ; 3. Crepitus. Make your examination gently and systematically ; at the same time, do not allow your fear of causing pain to prevent your satisfying yourself as to the real condition. The patient who makes a loud out- cry when you try to elicit crepitus will be just as ready to cry out against your reputation should you make a mistake in diagnosis. Take the sound limb for a model, and, comparing the injured member with it, satisfy yourself upon the following questions : I. Is there deformity? In many cases a glance will settle this point. When a long bone, such as the femur, is broken, an angle more or less obtuse is formed by the fragments, and the segments of the limb show a corresponding change in direction. When the fragments slip past each other there may be seen a bunching caused by the con- traction of the muscles, and the limb is shortened. To satisfy ourselves more thoroughly on this point measurements should be made. In the forearm and the leg both ends of the bones can be felt and the measuring tape applied. In measuring the femur fixed points on other bones must be taken. Place the patient flat upon his back with both limbs close together and perfectly straight. Apply the tape to the anterior superior spinous process of the ilium, and carry it down to the top of the inner malleolus. In the case of the humerus the acromion process is taken as a fixed point, and the tape carried to the lowest point on the external condyle. It must, however, be borne in mind that in many persons there is a difference in the length of the limbs which may be unknown to the persons themselves. This rarely amounts to more than a quarter of an inch, but in some instances it reaches an inch or even more. Another source of possible error is previous disease or injury which may have shortened one of the limbs. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 53 Swelling is an almost constant accompaniment of fracture and a source of deformity. It is often attended with heat and redness. On the second or third day large blebs, filled at first with a yellow and later with a bloody liquid, sometimes appear. These are more apt to occur in fractures of the leg and forearm. Fractures caused by direct v^iolence are liable to have injury of the soft parts, either immediate or showing at a later period in the form of sloughing. Fractures by indirect violence are often followed by extravasations of blood beneath the skin (ecchymoses), and, as a rule, at some distance from the seat of fracture. 2. Is there preternatural mobility ? If a joint-like movement is found in the shaft of a long bone, the evidence of fracture is complete. When the bone is broken near one or other extremity, however, this abnormal mobility is not so easily recognized. A fracture at or near a joint may be attended with an abnormal range of movement of the joint or with a mov^ement in an unnatural direction. 3. Is there crepitus ? This is a pathognomonic sign of fracture. It is the rough, grating sensation which is conveyed to the ear and hand of the surgeon, and with accentuated force to the feelings of the patient, when the broken ends of a bone are rubbed together. Crepitus is discovered by grasping the bone firmly above and below the seat of fracture, and causing sufficient movement of the fragments against each other to produce the grating sensation already described. The moment this is found cease further manipulation, for it will only do harm. Indeed, in some fractures we should not try to find crepitus ; in others we cannot find it if we try. In fracture of the neck of the femur with impaction we shall do positive injury by seeking for crepitus, and in immovable fractures, such as those of the cranium, crepitus is out of the question. 4. What is the nature of the displacement ? When the line of frac- ture is transverse to the long axis of the bone it is called a transverse fracture, and the displacement, if any, is lateral or it may be overlapping. If the line of fracture runs for some distance more or less exactly in the same direction as the long axis, it is called a longitudinal fracture, and in that case there is usually no displacement. The direction of the fracture may be intermediate between these two, and then it is called oblique. The tendency in this case is for the fragments to slip past each other, causing shortening of the limb, while the ends of the bone cannot be so distinctly felt as when there is a transv^erse fracture with overlapping of the fragments. The discovery of the Rontgen or x rays has placed in our hands a most satisfactory means of diagnosing a fracture and of demonstrating the actual position of the fragments. It is of especial value in fractures in the neighborhood of joints, in ununited fractures (see Plate I.), and in old injuries having an obscure clinical history. Besides the foregoing signs, which are objective, there are certain subjective symptoms which should be taken into account ; these are — {a) Pain. — This is a constant accompaniment of fracture. A simple contusion or a sprain is also attended with pain, and you may often find it impossible to say whether the injury is a simple bruise or a fracture. The safe rule in such a case is to give yourself and patient 54 SURGICAL DIAGNOSIS AND TREATMENT. the benefit of the doubt and treat it as a fracture. Perfect immobiliza- tion in splints is excellent treatment for a contusion or a sprain. The removal of the apparatus on the second or third day will i)robabIy show the case in a new li^ht, with swellini^ abated and pain absent. Then, if you can satisfy yourself that the bones are unbroken, your error has been on the side of safety. Pain, to be of any value to us as a symptom of fracture, must be constant and limited to one particular spot. If after a severe wrench of the foot, pain is felt over the fibula an inch or two above the ankle, much increased on pressure, even if every other symptom is wanting, we are justified in diagnosing a fracture. When pressure upon one point of a rib causes pain at another point, the evi- dence is strongly in favor of fracture. (/;) Hciplcss)icss of the Part. — As a rule, the patient can make no use of a fractured limb. The least motion causes suffering, so that pain or the fear of it compels him to keep the part at perfect rest. This has a salutary influence, for the movement of a fracture may be attended with considerable danger. A person suffering from fracture of the tibia may, by attempting to walk, force the fragments past each other and out through the skin, thus convertisg a simple into a com- pound fracture. The same is liable to happen in fracture of the fibula or of the clavicle. If there be marked impaction, or if the periosteum remain intact, or if one of a pair of bones is broken, it is possible for the patient to use the limb. I had a patient who walked several hun- dred yards after sustaining fracture of the neck of the femur, which was firmly impacted, and cases are reported of persons walking about for days in the same condition. In some cases of fracture of the clavicle it is possible for the person to raise the arm above the head on the affected side. Errors in diagnosis are liable to occur by our not distinguishing between fractures, separation of epiphyses, dislocations, contusions, and sprains. The greatest difficulty arises when the injury is in the neighborhood of a joint, and especially when there has been time for swelling to take place. Another disturbing element is the presence of previous disease in the joint, such as synovitis or rheumatoid arthritis. {a) Separation of Epiphyses. — This occurs in young children : the injury is near the extremity of the bone ; when crepitus can be felt it is of a softer character than that which is found in fracture ; in infants crepitation is wanting. The displacement is slight, for, as a rule, the periosteum remains intact and steadies the separated epiphysis. When the bone is near the skin its end can be felt, and it is rounded and smooth, not sharp and rough as in fracture. The most important practical point in the diagnosis of this accident is that separation of an epiphysis is liable to be followed by arrest of development. Repair usually takes place by osseous tissue ; hence the bone ceases to grow at the injured end, and if the patient has not completed his growth permanent shortening will result. In a case which came under my observation the femur was shortened one inch and a half in a young man sixteen years of age, who sustained this injury w^hen a child. In a single long bone, such as the femur or humerus, this shortening is not so serious as when it occurs in one of a pair. When the accident INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 55 occurs at the lower end of the radius, an arrest of development fol- lows, the styloid process of the ulna becomes abnormally prominent, the use of the hand is seriously interfered with, and, a most disagree- able deformity is the result. If our diagnosis is separation of the epiph- ysis, this danger should be pointed out to the friends of the little patient. {p) Dislocation. — Except in the presence of considerable swelling the diagnosis between fracture and dislocation is not difficult. In disloca- tion the joint is fixed, and cannot be moved except by force. When the deformity is rectified there is no tendency for it to return. True crepitus is wanting. It may be simulated by joint crepitus, effusion into the sheaths of tendons, emphysema, and by the grating of osteo- phytes in chronic osteo-arthritis. True crepitus, having once been felt, can hardly afterward be mistaken by the surgeon. The greatest dif- ficulty will arise at the elbow in cases where both dislocation and fracture exist. {c) Contusions. — The pain and helplessness caused by a severe con- tusion may closely simulate a fracture or a dislocation. The pain, or fear of it, compels immobility, and the rigidity of the muscles about a joint under these circurfistances is puzzling. Putting the patient under an anesthetic will greatly help us by relieving muscular contraction and pain. If, in spite of a painstaking examination, yon arc still unccrtai)i, treat the case as a fracture and Zt'ait for tzuo or three days. Complications of Fracture. — There are numerous conditions which may complicate fracture. They may be considered under three heads : I. Complications due to a General Effect upon the System. — Of these the most important is shock. The violence which causes fracture may be so severe as to affect the nervous system seriously, not only on account of injury to the bone, but to the soft parts as well. The ner- vous excitement and mental condition also play an important part. Shock is readily recognized by coldness of the skin and pallor of the face ; frequent, irregular pulse, the artery appearing to empty itself after each beat. The temperature is below normal, and may go down to 95° or 94° F. The breathing is shallow. Fever very frequently follows a fracture, and may partake of the character of fermentative or traumatic fever, due to the extravasation of blood and the absorption of the blood-ferment set free by the injured tissues. The temperature rises to about 100° or 101° F. by the evening of the second day, and is identical with the fever which follows aseptic surgical operations. In the case of compound fractures, where suppuration is allowed to take place, the character of the fever is different and is persistent. Retention of urine is a complication to be watched for, particularly in fractures about the pelvis. A catheter should always be passed ; if instead of urine a little blood escapes, while the patient states that the bladder was full at the time of the accident, we may infer that the blad- der is ruptured. If, however, the rent in the bladder is small or occluded by a loop of intestine, clear urine may collect in the bladder and come away through the catheter. Fat-embolism is, fortunately, a rare complication. In the process of 56 SURGICAL DIAGNOSIS AND TREATMENT. repair fatty degeneration takes place in the medulla, and perhaps in the subcutaneous tissue. Under ordinary circumstances and in the vast majority of cases this gives rise to no symptoms. Hut it occasionally happens that through the open mouths of veins which have been torn across a large number of these broken fat-cells are taken up and car- ried back to the right side of the heart, and from there sent to the lungs. The symptoms produced are collapse, coming on after an interval of several days and not immediately, as is the case in shock. It is a sort of secondary shock. The earliest indications are transient attacks of dyspnea with irregularity of the heart-beat, and in some cases slight hemoptysis. The pulse is small and rapid, and the breath- ing shallow and sighing in the advanced stage, running into the Cheyne- Stokes respiration. The mind becomes dull, weakness increases, and in many cases convulsions intervene before the approach of death. 2. Complications Due to Confinement of the Patient to his Bed. — Except in those suffering from other diseases or debilitated from age the confinement necessary during the repair of fracture is well borne. Constipation is very common, varying in degree from a simple inactiv- ity to obstinate constipation, attended with jaundice or gout. Con- gestion of the lungs is likely to appear in old or feeble persons whose circulation is languid and who cannot bear to remain long in the re- cumbent posture. Bed-sores constitute one of the most troublesome and distressing complications ; they appear only in the debilitated. The sacrum is the most common position, but they may occur over any of the bony prominences where pressure is made either by the weight of the patient or by ill-adjusted splints. Cleanliness is of the utmost importance in the prevention of bed-sores. The use of an air-cushion is also a great help, and when it can be possibly avoided the aged and feeble should not be treated by rigid confinement. 3. Local Complications. — Laceration of the soft parts occurs to a greater or less degree in almost every fracture. Attending this lacera- tion is extravasation of blood, but except when this is severe no atten- tion need be paid to it. The torn tissues speedily undergo repair and collections of blood are rapidly absorbed. Even when a considerable quantity of blood is poured out, forming a hematoma and raising the skin above the subjacent tissues, simple pressure and patience will bring the parts back to their natural condition. When, however, a larger vessel is torn, we have what is, practically, a traumatic aneurysm, and it must be treated as such. As long as the parts can be kept in an aseptic condition a moderate amount of extravasation of blood is not serious, but in compound fractures especially, where infection of the wound may occur, it adds a dangerous element. Simple fractures may also become infected by absorption of septic material through a bruised skin covering, as in a case of direct violence in which cleanli- ness has been neglected. Dead blood-cells and lacerated tissues form a most fertile culture-soil for septic bacteria. Where such collections can be got at in compound fractures, they should be carefully washed out and drained. If they extend along the limb, enlarge the opening and make incisions if necessary. Laceration or rupture of the main arterial trunk of the limb is a most serious complication. The most common accident of this kind INJURIES AND DISEASES OF THE OSSEOC'S SYSTEM $y occurs when the lower end of the femur is fractured and one of the frag- ments is driven backward upon the popHteal artery. Even when the bone fails to cut through the vessel, the inner and middle coats of the artery may be ruptured, curling themseh^es up within, and the vessel thus weakened gives way at a later period. Sometimes the rupturing of the inner and middle coats may favor the formation of a clot ; in such a case hemorrhage rarely occurs. When an arterial trunk is thus divided the symptoms develop rapidly. Swelling of a tense elastic character, steadily increasing, pain that is frequently excruciating, pul- sation above, but none in the artery below the injury, rendering the limb cold, edematous, and benumbed, — these are the prominent symp- toms. When there is a wound the blood flows freely, coming in jets when the opening is large and the vessel exposed, but when the exter- nal wound is small and tortuous the blood may come away in a steady stream. In compound fractures when a large vessel is torn we have two courses before us — either to find and ligate the vessel above and below the laceration, or, failing in this, to amputate the limb. Bleeding under such circumstances is difficult to check. In fractures by direct violence we expect more laceration than in those caused in other ways. The crushing of the soft parts, as when a car-wheel runs over a limb, de- stroys not only the main vessel, but the collateral circulation. The skin, owing to its toughness and greater resisting power, may seem but little the worse of the bruise. Do not be deceived by this, for the vessels and nerves may be utterly destroyed. Treatment of Lacerated Arteries. — Place a tourniquet upon the limb. Enlarge the wound and find the bleeding point. It is always difficult to find an arter}^ that is torn in this manner. If the vessel cannot be found in the wound, it is of no use to ligate it higher up, for, if the collateral circulation be good, bleeding will continue ; if the collateral circulation cannot be maintained, gangrene is a certain consequence. We should, however, give a fair trial to compression of the vessel higher up, for it will settle the question of collateral circulation, and in many cases it has been successful in permanently arresting the hemor- rhage. In simple fracture, when we can feel that the circulation is not com- pletely arrested, the limb retaining its warmth and sensation, it is best to wait. The bleeding may cease, owing to pressure of the tissues, or the wound in the artery may close and the extravasated blood become absorbed. The limb should be placed in an deviated position, wrapped in cotton to maintain an even temperature, and only such bandages and splints applied as are necessary to keep the parts at perfect rest with gentle compression. If, however, the limb is found to be cold, the artery below the injury pulseless, and the swelling tense and rapidly spreading, it is evident that gangrene will supervene, and the only course is to amputate. Rupture of veins is rare. A fracture of the clavicle sometimes tears the subclavian vein, and the popliteal vein has been ruptured by a frag- ment of the femur. But, as a rule, the veins escape much more frequently than the arteries. The cases in which they suffer are those 58 SURGICAL DJAGXOSIS AND TREATMENT. in which the injury is severe and both arteries and veins are impHcated. The symptoms are very similar to those ah'eady mentioned, with the exception of pulsation. The treatment consists in making a free open- ing into the swelling, turning out the clots, and ligating both ends of the vein. Thrombosis and embolism are also complications which must be taken into account. In one case reported by Southham thrombosis appeared on the seventeenth day, in another on the six- teenth, and in one reported by Tyrrell on the twelfth day. Iiijiny to Ahi'vcs. — The nerves, owing to their strength and tough- ness, are seldom injured in fracture. A nerve may slip between the fragments, not only suffering injury itself, but preventing the union of bone. The most common complication, however, is at a later stage, and due to the nerve being caught in the callus, which in the process of ossification exerts sufficient pressure to cause pain and interrupt the nerve-function. Of all the nerves, the musculo-spiral is the one ^\•hich is the most frequently involved. When the nerve is simply irritated the symptoms are neuralgia, spasmodic contraction, and hyperesthesia. When the nerve is compressed, the pain is constant, and, as degeneration takes place, there is loss of power, wasting, and diminished sensibility. Diagnosis and Treatment of Special Fractures. The Nasal Bones. — A violent blow upon the nose, followed by copious hemorrhage, should lead us to suspect fracture of the nasal bones. This fracture is frequently overlooked both by patients and surgeons. The swelling, which comes on rapidly, obscures the symp- toms, and, as the nose is a very sensitive organ, patients are often reluctant to submit to a thorough examination. The commonest situation of the fracture is near the lower ends of the bones. The fragments are driven backward, but sometimes they are found to be forced to one side, and the septum is frequently involved. The fracture is often compound, the fragment perforating the skin, the mucous mem- brane, or both. Besides local pain, there are severe headache, copious hemorrhage, and sometimes emphysema in the surrounding cellular tissue. In your examination look for deformity. This may be both seen and felt, but may be masked by swelling. If not satisfied with an examination of the external parts, look into the nostrils, and, if they are filled with blood, explore them gently with a probe. Crepitus can be felt, but usually the symptoms are clear enough without this, and the manipulations necessary to find it might cause further laceration and do harm. Treatment. — If properly replaced, fractures of the nasal bones unite VQ.xy rapidly. Hippocrates declared that perfect union took place in six days. Hamilton relates a case in which a cure was effected in seven days. Take a small, strong instrument, such as a director or fine sound, and press the fragments upward from the inside, while the finger and thumb of the other hand mould the parts from without. It must be borne in mind that the nasal passage at the point where pressure is required is very much narrowed, owing, not only to the displaced frag- INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 59 merits, but also to the swelling in the mucous membrane. The canal is so small that it will not admit objects much larger than a probe. A lead pencil or an instrument wrapped in cotton is not suitable. When such is used, it is stopped before it reaches the point at which pressure is required, and the operator pushes upward against the nasal process of the superior maxilla. Finding a resistance which cannot be over- come, he, after repeated attempts, leaves the case with the bones un- reduced. When the fragments do not remain in position after being replaced, a nickel-plated needle may be passed through the nose from side to side just below the fractured bones, and the parts held in place by a rubber band crossing the nose from one end of the needle to the other. Hemorrhage can be stopped by injecting the nares with ice-cold water or by the application of an ice-bag. If the hemorrhage cannot be thus controlled, the posterior nares should be plugged. A good method of effecting this is either by the india-rubber inflating tampon or by the assistance of Bellocq's sound. By the former method the india-rubber tube which is used has two dilatations upon it, so shaped that when inflated they accurately fill the posterior and anterior nares re- spectively. It is passed in while flaccid by means of a long probe, and inflated when in position by means of a small syringe or by the mouth. Reinflation is necessary from time to time. By the latter method a pledget of lint or cotton-wool rather larger than the aperture to be filled is taken, and round the middle of this is tied a doubled piece of stout thread, a long loop being thus left on one side and two ends on the other, one of which is cut off short. The sound is then armed with a separate length of thread and passed closed through the nostril, and when the end has reached the pharynx the spring is projected, coils around under the soft palate, and appears with the thread in the mouth. The thread is then pulled through the mouth, thus leavdng one end through the mouth, the other through the nostril. By making traction on the nose-end of the thread the pledget is guided by the finger in the mouth into the posterior nares. The loop of thread is firmly tied to an anterior loop, which is forced into the anterior nares, and the other end is allowed to hang in the pharynx or outside the mouth. Fracture of the Malar Bone. — The most common position for fracture of this bone is at the zygoma, and it is always caused by direct violence. The prominence of the bone and the sharp outline of its orbital margin make diagnosis comparatively easy. As a rule, this bone is fractured in some serious injuiy which involves other bones of the face and skull. Fracture of the Upper Jaw. — -The whole bone may be driven in by direct violence, causing extreme deformity, or the wall of the antrum may be fractured, or the fracture may run along above the alveolar margin, so that the teeth are movable as if they were a set of false teeth. The diagnosis must be based upon the deformity, the nature of the accident, hemorrhage, and mobility of the part. A guarded prognosis should be given, as the brain or bones of the skull may be seriously involved. Treatment. — It frequently happens that direct pressure with the 6o SL-RG/CAL DIAGNOSIS AND 'J-REATMENT. fingers is sufficient to correct the displacement and no retentive appa- ratus is necessary. When the alveolar border is the seat of fracture and the fragment is movable, it may be necessary to maintain the parts in proper position by wiring the teeth in the detached bone to those which arc still in ])osition. Fracture of the I/Ower Jaw. — This fracture may result from direct or indirect violence. The most frequent seat of injury is near the canine tooth and immediately in front of the mental foramen. The angle, the symphysis, the neck of the condyle, and the coronoid process must all be examined. When the fracture is compound the breach of the soft parts is generally in the mouth. The teeth are frequently loosened or completely separated. By passing the fingers over the surfaces of the bone any irregularity can be felt, and in most cases crepitus can be produced. When the fracture is through the horizontal ramus one of the fragments drops to a slight extent, owing partly to its weight, but chiefly to the action of the muscles attached to the hyoid bone. When the bone is broken at its neck the condyle is drawn out of its socket by the action of the pterygoid, while the rest of the jaw is drawn toward the opposite side by the other muscles. Pain is severe, and particularly when any attempt is made at masti- cation. The patient finds it difficult to speak, and steadies his jaw with one hand. Trcatnioit. — In simple cases the parts are easily kept in position. A good retentive apparatus is the following, which I quote from Mansell Moullin : " One webbing strap is placed beneath the jaw, carried upward on either side over the temporal region, and fastened a little in front of the vertex ; and a second is placed horizontally around the forehead and below the occipital protuberance. Where they cross a slit should be cut in the horizontal one to allow the other to pass through, or they should be sewn together, and for additional security they may be connected by a tape over the sagittal suture. Buckles, protected underneath with little wash-leather pads, should be used to secure them. In ordinary cases there is no tendency to displacement forward ; but if, owing to the convexity of the lower margin of the jaw, the vertical band is inclined to slip too far back, it may be secured in position by a tape stitched to it and passed in front of the chin." The four-tailed bandage is a time-honored appliance, but much inferior to the above method, as it has a tendency to become loose and untidy. A splint of gutta-percha moulded to the part is an excellent method when, owing to the obliquity of the fracture, lateral pressure has a tendency to displace one of the fragments inward. Interdental splints of various kinds have been invented, and excel- lent results have been obtained by wiring the fragments, either through the medium of the teeth or by drilling holes in the jaw itself Fracture of the Clavicle. — Of all fractures, this is the one met with most frequently. It occurs generally as the result of indirect violence, as when the patient falls to the ground, alighting upon his shoulder. The most common position of the fracture is in the middle of the bone or a little farther toward the outer end. By direct violence any part of the bone may be broken. The position assumed by a person INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 6l with a fractured clavicle is so characteristic that a diagnosis can almost be made from that alone. The head is inclined toward the injured clavicle, and the free hand is used to support the arm on the injured side. The shoulder slopes more than in health, and is drawn nearer the middle line of the body. A projection may be seen over the clav- icle, and if not seen it can be readily felt by passing the fingers along the bone, when the exquisite pain at that particular point and the pres- ence of a sharp projection leave no doubt of the nature of the injury. It is not worth while looking for crepitus and increased mobility, as the patient's sufferings are greatly aggravated by any manipulations. The only exception to be made is when the fracture is at the coraco- clavicular ligament. Here the symptoms to be relied upon are tender- ness and slight crepitus when moderate pressure is made. In children the fracture is often incomplete, the so-called grcoi-stick fracture. Displacement. — When the fracture is incomplete there is a simple elevation about the middle of the bone. When the fracture is complete the displacement is much more marked. The inner fragment remains undisturbed, for it is steadied by the rhomboid ligament and the costo- coracoid membrane below and the sterno-mastoid muscle above. Some- times, however, the outer end of this fragment is drawn upward against the skin, which it may even perforate. The outward fragment is the one which is displaced — first, downward by the weight of the arm ; second, inward by the action of the pectoral muscles ; third, forward by the action of the serratus magnus and pectorals, which rotate its outer end until it forms an angle with the true axis of the bone. TreatmeJit. — To effect reduction the shoulder must be drawn in the direction exactly opposite to the displacement — viz. upward, backtcard, and outivard — and the parts must be kept in this position. The sim- plest appliance for this purpose is Sayre's dressing. Take two strips of adhesive plaster (spread on moleskin ; cotton is too weak) three inches wide and of sufficient length to go once and a half around the chest. Pass the end of one strap around the arm of the affected side just below the axilla, and fasten securely, but not tight enough to inter- fere with the venous circulation. Draw the shoulder well back and carry the strap around the chest, so as to hold the arm with the elbow a little behind the axillary line. Now place the forearm of the injured side across the chest, so that the fingers point to the opposite shoulder. Carry the second strip from the uninjured shoulder across the back to the opposite elbow, and up along the forearm to the place of begin- ning ; at the same time the elbow must be pressed forward, inward, and upward (Fig. i6). Absorbent cotton or other suitable material should be placed between the forearm and chest, lest retained moisture cause irritation and perhaps ulceration of the skin. The parts may be still further supported by a few turns of a bandage about the arm and chest. Velpeau's bandage (Fig. i/) is a time-honored method of treating fractured clavicle, but has no advantage over Sayre's dressing. Should you happen to be so situated that suitable materials are not at hand, a very efficient appliance can be made by the use of two good-sized handkerchiefs or pieces of calico about one foot and a half square. Fold each handkerchief till two opposite corners meet, then fold it into 62 SCA'G/C.I/. 7^/AGXOS/S AND TREATMENT. a band about four inches wide. Around each shoulder pass a hand- kerchief thus folded, and tie the ends in a single knot over the scapula. Now draw the shoulders well backward, and retain them in this posi- tion by tying the two ends of the right handkerchief to the two ends of the left. The arm is next flexed across the chest, and a sling applied to support the forearm and elbow. When Sayre's and Velpeau's methods are objectionable, the patient may be placed in the recumbent position with a sand-bag under the scapula of the affected side. The shoulder is then weighted with anything that will steady the parts. The fragments naturally coapt themselves in this position. When union has partially taken place suitable bandages are applied until repair is complete. Union may be expected in about four weeks in adults, but it is well to warn patients that there is always more or less deformity result- ing from thickening of the bone. The thickened bone may even make (■^ Fig. i6. — Sayre's adhesive-plaster dressing for fracture of the clavicle (Stimson). Fig. 17. — Velpeau's bandage. pressure upon the nerves of the brachial plexus, as occurred in two cases which came under my notice. This result is uncommon. It is seldom that any complications attend fracture of the clavicle. But it is possible, particularly in fracture caused by direct violence, to have injur)^ to the vessels and nerves, and even perforation of the lung. Laceration of the subclavian vein or the internal jugular is a serious accident, and unless promptly treated is attended with fatal results. Fracture of the Hyoid Bone. — This is a rare fracture. It often occurs in hanging, in which case the body of the bone is broken, or by the force of the thumb and finger when the throat is grasped by an assailant. In this case one of the greater cornuae is the part to suffer, or at the junction of the body with the cornua. Blows upon the throat and even muscular contraction have been observed as causes. Syiiiptoins. — The victim may feel a sensation as if a bone had broken ; severe bleeding may take place, more especially if a fragment has perforated the mucous membrane. There is difficulty in swallow- ing, dyspnea, salivation, and inability to speak. Severe pain may be felt in moving the tongue, and in some cases the tongue is drawn to one side. The greatest danger is in death from edema of the glottis. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 63 Treatment. — Pass a finger into the throat and draw the base of the tongue as far forward as possible, while with the other hand the depressed bones are moulded into proper position. No retentive apparatus can be applied, and all that needs to be done is to keep the parts at rest for a few days by not using the voice and swallowing no food. Nourishment can be administered by the rectum. Fracture of the Sternum. — Look for this fracture at or near the junction of the manubrium and the body of the bone. It has been pro- duced by lifting heavy weights, by severe straining during labor, or by excessive bending of the body. It is usually simple and transverse, but may be multiple. Two cases which I have attended were produced by direct violence. The symptoms are not usually well marked. Dis- placement may be slight, for the periosteum on the inner surface of the bone is usually untorn. When the body of the sternum is fractured it is usually in its upper half Diagnosis must be based upon the history of the injury, localized pain, and displacement felt by pressing the fingers over the bone. Dyspnea and irregularity of the heart have been noted as symptoms. The head and shoulders are bent forward to relieve the pain. Treatment. — While the patient makes a deep inspiration force the bone into position by direct pressure, aided, if need be, by extension of the trunk. A broad band of adhesive plaster around the chest, with a pad between the shoulders, is the best appliance for retention. Fracture of the Ribs. — When a rib is fractured it breaks com- pletely, green-stick fracture being rare. The man who can diagnose frac- ture of the ribs and never make a mistake is a good surgeon. I have seen more errors made in this fracture than in any other. The ribs most liable to suffer are those from the fifth to the ninth. The first of these is probably broken more frequently than is recognized ; the remain- ing upper ribs are seldom fractured, and the false ribs perhaps never, except in gunshot wounds. One or several ribs may suffer, and one or several may be broken at two points each. Do not expect to see any deformity unless several ribs are fractured and the chest-wall, as sailors say, " stove in." External violence is the commonest cause, and it may act in one of two ways : directly, as happened to a patient of mine, who, while riding along in an open buggy, received a severe blow from the end of the pole of a carriage which was following too closely behind ; or indirectly, as when the chest is compressed and the natural curve of the ribs is thus forcibly increased. Muscular action has produced fracture in fits of severe coughing — a rare occur- rence. Diagnosis. — Our suspicion of fracture should be aroused if the patient after an injury to the chest complains of pain on drawing a deep breath or on coughing, and especially when pressure is made on one particular spot in the chest-wall. Place your hand upon the pain- ful spot and ask him to take a deep inspiration ; when fracture exists a sensation of crepitus is felt by the hand, and the patient also feels the sensation in his side. With the point of the fingers find the tenderest spot and feel for any irregularity in the bone at that place. Next place a finger on the suspected rib on each side of the fracture, and you will perhaps find that mov^ement communicated to one frag- 64 SURGICAL DIAGNOSIS AXD TREATMENT. nicnt is not transmitted to the others. Place your stethoscope or ear o\-er the suspected spot, and crepitus may be detected on deep breathing. Expectoration of blood is a common symptom, and so is cellular emphysema. As a rule, emphysema, when it occurs, extends over several square inches of the surface, but a few cases are recorded in which it spread over nearly the whole body. If the fracture is com- pound, we often find the intercostal artery wounded. The most common seat of fracture of the ribs is at or near the angle, about four inches from the vertebral column. A contusion may closely simulate fracture, for it will produce pain and difficulty of breathing which is diaphragmatic. A fracture may show nothing more, for there may be no hemoptysis, and in some cases it is impossible to elicit crepitus. When uncertain, give fracture the benefit of the doubt ; immobilization of the chest-wall will give the greatest comfort in contusion, and is also the proper treatment for fracture. Treatment. — Take a band of adhesive plaster about six to nine inches broad and carry it around the chest, overlapping about one- half. If this is not convenient, use several narrow strips of plaster, and get complete immobility of the affected portion of the chest-wall by apph'ing strips vertical!}'. Fracture of the Scapula. — Great force is necessary to break the scapula, for behind it are the elastic ribs and a cushion of muscular tissue over which it readily slides when subjected to a blow. Swelling occurs speedily, and makes the diagnosis more difficult than in most bones, and hence errors must be guarded against. Seven different fractures of the scapula are recognized — viz: i. The body ; 2. The inferior angle ; 3. The superior angle ; 4. The spine ; 5. The acromion process; 6. The coracoid process; 7. The neck. The Body. — Pass the fingers along the posterior border of the scapula, at the same time placing the bone in such positions as elevate its margins and render them more prominent. If fracture exist, there will be overlapping of the fragments. Grasp the lower angle and crepitus may be found, but it must be remembered that overlapping on the one hand and wide separation on the other will prevent our finding crepitus. The Inferior Angle. — Lay the forearm across the back, and the angle is thrown out so that the fingers can be easily pushed behind it. If the angle is broken off, the displacement is forward and upward by the action of the attached muscles. TJie Superior Angle. — Place the hand of the injured side upon the opposite shoulder, with the forearm lying across the chest. This throws the superior angle into prominence, when it can be examined. The symptoms of fracture here are obscure, as there is little displacement and often great swelling. The treatment consists in keeping the arm immobilized. The Spine. — In thin persons the spine of the scapula can be readily felt, particularly when the injured arm is placed behind the back. By direct violence the spine may be broken off throughout its entire length, including the acromion process, or a portion of it may be broken off, leaving the acromion process attached to the body. The INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 65 displacement is slight, and the evidence must rest upon the mobility of the fragment detached. The treatment is immobilization. T/ie Acromion Process. — Fracture of this portion of the bone is produced by direct violence, by indirect violence as when the humerus is pushed violently upward, and possibly by muscular action in violent contraction of the deltoid. Mobility, when it exists, is the most import- ant symptom ; there may also be crepitus, and there is always tender- ness on pressure. An error in diagnosis is apt to be made in cases where the epiphysis at the external end of the spine has failed to unite. This condition, combined with a contusion, might readily be mistaken for fracture. Beginning posteriorly, run the fingers along the spine toward the acromion to search for any irregularity, fissure, or depres- sion. The acromion may next be grasped to test its mobility and to elicit crepitus. Three separate lines of fracture are to be recognized — viz. in front of the clavicle, through the articulation with the clavicle, and posterior to the articulation. In the first of these the clavicular attachment is not interfered with, and hence the position of the arm in its relation to the body will not be changed. In the two latter forms the clavicle is involved, and the result is that the shoulder assumes the very position which it takes in fracture of the clavicle — viz. downward, forward, and inward. Trcatvicnt. — Immobilize the arm at the side of the body, the elbow a little forward, and the humerus pressed well upward against the acromion. TJie Coracoid Process. — The coracoid process can be felt in the space between the anterior border of the deltoid and the pectoralis major. When fractured by muscular action, as sometimes happens, the dis- placement is downward by the action of the coraco-brachialis. When not detached, the finger resting upon the tip of the process can detect mobility, and perhaps crepitus. The treatment is immobilization of the arm against the chest, with the elbow drawn slightly backward. The Neck. — The most prominent symptom in this variety of fracture is a falling down or flattening of the shoulder. The humerus sinks down, owing to the loss of support from the triceps. When the arm is pressed upward this deformity disappears, to return as soon as the arm is left unsupported. Follow the axillary border of the scapula upward, and in the axilla you will find a movable, hard lump. By an upward and backward movement crepitus can be detected. The indi- cation for treatment is to prevent sinking of the humerus. This can be accomplished by the application of a Velpeau bandage or a strip of adhesive plaster passing into the flexed elbow and over the shoulder of the same side. Fracture of the Humerus. — Fracture of the shaft of the humerus is very easily diagnosticated. The deformity is usually well marked. Pain is intense and helplessness complete. The fragments can be felt through the skin and crepitus is readily detected. The brachial artery is rarely injured, but the musculo-spiral nerve not infrequently suffers, either by direct injury at the time of the accident, or at a later period it may be compressed in the callus. In children the fracture is generally transverse, and this is often the case also when due to muscular exertion. In adults the common direction is obliquely from above downward and outward. When the fracture is above the 66 SURGICAL DIAGNOSIS AND TREATMENT. insertion of the deltoid, the upper fragment is drawn inward by the muscles of the chest ; the lower fragment is drawn outward and upward by the action of the deltoid. When the bone is broken below the insertion of the deltoid, the relation of the fragments is not much disturbed, for the muscles antagonize each other. Probably, of all bones this is the one in which non-union or a false joint is most likely to occur. The reason of this is not to be sought in any fault of the bone itself, but from the fact that, owing to the great leverage of the lower fragment, it requires the utmost care to keep the parts completely immobilized. Non-union is also due in many cases to the interposition of muscle or fascia between the fragments. Treatment. — Bend the elbow to a right angle, and by extension in the axis of the bone, aided by direct manipulation, replace the frag- ments. Sometimes a considerable amount of traction is necessary to effect this, and in the case of compound fractures the ends of the frag- ments may have to be cut off A good retentive apparatus is the shoulder-cap splint, long enough to reach the elbow and enveloping two-thirds of the circumference of the arm (Fig. i8). If narrower than this, a short internal splint should be used. The arm is to be carried in a sling and the elbow left un- supported. A weight may be at- tached to the elbow when the patient is able to go about, and this is especially indicated when he is a muscular man. Plaster of Paris is an excellent dressing. It need not be made so bulky as to render it objectionable from its weight, on account of which some writers have condemned it. Fractures of the upper exd OF THE humerus are divided into those of the head, of the anatomi- cal neck, of the tuberosities, sepa- tion of the epiphysis, and fracture of the surgical neck. 1. Fracture of the head cannot be recognized during life. 2. Fracture of the anatomical neck is a rare accident. When an Fig. i8. — Apparatus for fracture of the hu- merus at any point above the condyles. anterior dislocation of the shoulder takes place, it is possible for the anterior lip of the glenoid cavity to act as a wedge against which the head of the humerus is broken off The same thing can occur when a strong force applied to the elbow drives the humerus upward against the scapula. It may also be the result of muscular action. Diagnosis. — Grasp the tuberosities of the humerus, which can be felt through the fibers of the deltoid, and rotate the arm. If the tuberosities move with the shaft and crepitus is found, the fracture is at the anatomical neck. When dislocation also exists the head can be felt to move independently of the shaft. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 6/ Trcatnioit. — The action of the deltoid and other muscles of the ■ shoulder tends to draw the shaft upward, while the head at the same time slips downward. To obviate this, the proper treatment is to make traction from the elbow and immobilize the arm. In most cases the shoulder-cap with a folded towel in the axilla is a good appliance. 3. Fracture through the tuberosities is usually the result of direct violence, and the bone is often comminuted and the fracture compli- cated with extensive injury of other structures. When the greater tuberosity is broken, it is generally as a complication of anterior dis- location. It is recognized by the want of voluntary outward rotation, by crepitus, pain, and swelling. 4. Separation of the epiphysis does not occur in persons over twenty years of age. The symptoms are the same as those of the surgical neck, except that true crepitus is wanting, and the end of the bone, when it is possible to feel it, is more rounded than when frac- tured. 5. Fracture of the Surg-ical Neck. — While the preceding fractures of the humerus are rare, this one is quite common. It is produced by direct violence or by a fall upon the elbow or hand. Grasp the head of the humerus with the thumb and fingers of one hand and rotate the elbow with the other. If crepitus and increased mobility are recog- nized, the case is clear. The displacement may be such as to give the appearance of dislocation at the shoulder. The point is easily settled by means of Dugas's test. Place the hand of the affected side on the opposite shoulder and bring the elbow to the side of the chest. If this can be done, there is no dislocation. Another method is by Cal/azuays test. Pass a tape around the acromion and under the axilla; if there is dislocation, the affected side will measure about two inches more than the sound one. Treatment. — Considerable difficulty may be found not only in re- ducing this fracture, but in keeping it in proper position. Firm traction must be made until the lower fragment can be got into line with the upper. A wedge-shaped pad formed of a towel in the axilla, with a cup-shaped shoulder-splint, will usually prove satisfactory. If, how- ever, displacement recurs, a weight must be attached to the elbow. About five pounds is sufficient. A sling supporting the wrist is needed in all cases. When fracture and dislocation both exist the usual practice is to attempt to reduce the dislocation, under an anesthetic, by direct manipulation. Failing in this, two other courses are open : either to set the fracture in the hope of reducing the dislocation at the end of four or five weeks, or allowing a false joint to take place. Both of these methods are unsatisfactor}^ A method which promises to give much better results is one employed by Dr. McBurney in a case reported in the Annals of Surgery for April, 1894. He thus describes it : " An incision should be made through the soft parts down to the bone, a hole drilled in the bone, a stout hook inserted, and direct trac- tion made upon the upper fragment in the proper position " (Fig. 19). Having reduced the dislocation, the fracture must be treated in the ordinary way. When impaction is found to exist, no attempt should be made to 68 SURGICAL DIAGNOSIS AND TREATMENT. reduce it, for it will ensure bony union. In cases where no impaction takes place there is a risk that nothing better than fibrous union will be obtained. Fractures at thp: Lowkr End of the Humerus. — When the elbow is bent at a right angle three bony prominences are arrayed in hne at the back of the joint. These are the internal cond)'lc, the olecranon process of the ulna, and the external condyle. Any disturb- ance of this relation will show that something is wrong. The fractures to be met with at the lower end of the humerus are clinically divided into — (i) those that are external to the joint, and (2) those that involve the joint. The fractures external to the joint are three in number — viz.: i. Transverse fracture above the olecranon fossa ; 2. Separation of the external epicondyle ; 3. Separation of the epiphysis of the same. The fractures which involve the joint are — 1. T-shaped fracture ; 2. Separation of the internal condyle ; 3. Separation of the external condyle ; 4. Separation of the lower epiphysis. Transverse fracture above the condyles is produced by falls upon Fig. 19. — Fracture-hook. the elbow, by direct violence, or by overextension of the elbow. The direction of the line of fracture is sometimes transverse ; at other times it is oblique from above downward and forward. At first sight the deformity resembles that of dislocation of both bones backward. But if the relation of the bony points already referred to is found to be undisturbed, there cannot be dislocation. Besides this, the position of the deformity is farther up the arm, causing an apparent shortening of the humerus. The elbow-joint is flexed with the hand, generally in pronation. In front there is a prominence, which is the lower end of the upper fragment, while posteriorly there is a depression above the olecranon which is bridged over by the tendon of the triceps. Add to this the existence of shortening of the humerus, the presence of pre- ternatural mobility, and, as a crucial test, crepitus, and no doubt can remain as to the existence of fracture. Treatment. — When the line of fracture is oblique it is difficult to prevent shortening, as the action of the muscles tends to cause over- lapping of the fragments. Both diagnosis and treatment are often interfered with by excessive swelling, which must be got rid of before the application of a permanent dressing. If the case can be seen and INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 69 the fracture set immediately after the injury, this swelHng will be pre- vented. If seen later, the swelling can be reduced by cold applications, followed after a few hours by gentle compression. For this purpose absorbent cotton and a bandage are the best, great care being taken to watch the fingers, lest circulation in the arm be interfered with. The best splint is strong pasteboard, cut in a rectangular form, running from the axilla to the wrist. After soaking in hot water this can be moulded to the parts, and it closely adapts itself to the limb. The splint should be applied along the posterior aspect of the arm and the under surface of the forearm. A short anterior splint should be applied down the arm, with a thick padding opposite the bend of the elbow, with a view to prevent forward displacement of the upper fragment. The arm must be carried in a sling. Passive motion should be employed about the end of the second week. Great care must be taken lest the newly-formed callus be broken up and a failure of union result. Fracture of the internal epicondyle may be a complication of dis- location, or may occur by itself as a result of direct violence or by muscular action. The diagnosis is often obscured by swelling, but in many cases the bone may be grasped by the thumb and finger and crepitus elicited. When external to the capsule of the joint, as the separation of this process of bone usually is, the accident is not of serious moment. Besides crepitus, the other symptoms are pain on pronation and also on extreme flexion and extension, while a moderate degree of either of the two latter movements is free from inconvenience. Treatment. — Carry the arm in a sling with the elbow at a right angle. Fractures into the Joint. — i. The most important of this group is a transverse fracture of the lower end of the humerus, with a vertical fracture running from it into the joint. For convenience' sake we speak of this as a T-shaped fracture. The cause is always direct vio- lence. The lower end of the humerus is split between its condyles by a wedge, and the wedge which splits it is the olecranon process of the ulna. From the tip of this process, running backward along the greater sigmoid cavity, is a ridge which, when driven with great force against the humerus, cleaves the bone from its articular surface upward and breaks it off transversely, producing the T-shaped fracture. Diagnosis. — The symptoms are very similar to those of supra- condyloid fracture, of which this may be regarded as an aggravated form. The lower end of the humerus being split, the condyles are spread apart, and consequently the end of the humerus appears to be wider than normal. The radius and ulna are displaced upward and backward, but the three bony points are still in line, so we have no dislocation. The humerus is shortened and there is increased mobility. Crepitus can be detected in two places — at the transverse fracture and also when one condyle is rubbed against the other. This is one of the most difficult of fractures to deal with. So rapidly does swelling come on that it interferes with the diagnosis. Reduction may be by no means easy, while union without more or less stiffness in the joint is rare. The patient and his friends should be explicitly warned on all these points the moment the nature of the 70 SURGICAL DIAGNOSIS AND TREATMENT. injury is made out. Violent inflammation in the joint and around it may be looked for, and deformity with bony ankylosis is exceedingly common in spite of the most careful attention. Treatment. — So unfavorable has been the prognosis in this fracture that surgeons have been in the habit of putting the arm in the position which would give the least embarrassment should bony ankylosis result. That position is at a right angle or a little more. The first part of the treatment will probably consist in dealing with a greatly swollen and inflamed joint, more particularly if the injury is not seen almost immediately after its occurrence. Reduction must, if possible, be effected at once. Extension and counter-extension will disengage the olecranon (the wedge which has split the humerus), and the condyles which have been spread apart can then be pressed back into position. The fragments must be brought into line with the shaft of the humerus, and moulded, as it were, by direct manipulation. For the first week this will need frequent attention, so that a faulty position can be recti- fied. At the end of the second week the callus will have become so firm that no further readjustment can be made. It has been the com- mon practice to put this fracture up in exactly the same kind of splint as that recommended for fracture above the condyles. Within the last few years the treatment of fractures in the neigh- borhood of the elbow-joint has received considerable attention. The method of setting the fracture with the arm in the extended position has been strongly recommended, and several cases have been recorded to demonstrate the superiority of this plan. Unfortunately, the matter has not been satisfactorily disposed of, for the success of the extended position is by no means uniform. Dr. James S. Wight in the Ajinals of Surgery for August, 1893, reports 10 cases treated in this manner, in all of which bony ankylosis followed; 5 of these joints had to be resected, and 4 others were treated by brisement force. If the advocates of the straight position could show that uniformly good results were obtained by this method, it would be wrong not to adopt it, but that evidence is wanting. In the mean time, the safer course is to put the arm up in that position in which, should ankylosis take place, the limb will be most useful. Midway between flexion and extension, in the main, gives the best results. I have had 3 cases so treated in which the usefulness of the limb is perfectly restored and the deformity insignificant fracture of the Internal or External Condyle. — Owing to its prominence the internal condyle is broken more frequently than the external. When a person falls backward, as upon an icy sidewalk, it is the internal condyle that is likely to be the first to come in contact with the ground. The fracture is apt to run into the trochlear surface of the joint. The external is rarely fractured : it may be the result of direct violence or of a fall upon the hand. The symptovis are very similar to those found in the T-shaped frac- ture, but not nearly so severe. In the case of the internal condyle the fragment is displaced upward and backward. This throws the exter- nal condyle into undue prominence. By grasping the condyle between the thumb and fingers crepitus can be discovered. When placed in position, contraction of the triceps tends to renew the displacement. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. J I The same result follows pressure upon the ulna near the elbow. For this reason the arm, when carried in a sling, should be supported only at the wrist. Treatment. — Carefully replace the fragment, and apply a rectangular moulded splint along the back of the arm and forward to the wrist. The forearm rests upon the splint with the palm downward, in order to relax the flexors and the pronator radii teres. The complications of this fracture are dislocation of the radius back- ward and the formation of exuberant callus, which may impair the movement of the elbow after union has taken place. Fracture of the external condyle is treated by immobilization in a posterior rectangular splint or a plaster-of-Paris cast. Separation of the Epiphysis. — At the lower end of the humerus are four centers of ossification — viz. one at the radial portion of the articu- lar surface, which appears about the end of the second year and extends inward to form the chief part of the articular end of the bone ; one to form the inner part of the articular surface, appearing about the twelfth year ; one for the internal condyle, appearing about the fifth year ; one for the external condyle, appearing about the thirteenth or fourteenth year. The outer condyle and both portions of the articulating surface unite with the shaft at the age of sixteen or seventeen years. The inner condyle becomes joined at about the age of eighteen. In infants a common accident is to have the whole of the car- tilaginous mass at the lower end of the humerus separated from the shaft. The same may occur in children, and the joint may or may not be involved. The most common cause is excessive adduction or abduc- tion of the forearm with hyperextension. The treatment is the same as for supracondyloid fracture. Fracture of the Ulna. — The olecranon may be fractured by a blow or a fall upon the elbow, or it may be wrenched off by forcible contraction of the triceps muscle. If the periosteum remains intact, the displacement is slight, but otherwise the fragment may be drawn upward by the triceps to the extent of two inches or more. Syjnptoms. — Diagnosis of this fracture is generally attended with little difficulty. The nature of the accident and intense pain over the point of the elbow are very suggestive. If there is no displacement, crepitus can generally be felt ; if the fragment is drawn upward, its absence from the normal and presence in the new position leave us no longer in doubt. Treatment. — When the periosteum is intact and the fragment remains in contact with the ulna, no other treatment is necessary than a sling, with immobilization of the arm or a plaster-of-Paris cast. In most cases, however, the displacement will be considerable, and this treat- ment will not suffice. The elbow must be placed in almost full exten- sion, immobilized, and the fragment drawn down to its proper position. The simplest way of doing this is by means of a piece of adhesive plaster cut in the form of the letter U. The curve is placed on the back of the arm just above the fracture, and the sides are drawn down and applied to the sides of the forearm. Cutting down upon the frag- ment and wiring it to the olecranon has been practised, but the cases in which this should be resorted to are rare. yi SURGICAL DIAGNOSIS AND TREATMENT. Fracture of the coronoid process is rare. It occurs, as a rult-, when there is backward dislocation of both bones. A fall upon the hand when the elbow is extended will also produce it, and of course it can be produced by direct violence. Muscular action does not cause it, for the only muscle that is attached to it is the brachialis anticus, and this is also attached to a considerable portion of the shaft of the ulna. For this reason there is little displacement when the process is broken off. Syjiiptovis. — Extend the elbow-joint and the bones of the forearm become displaced backward. Traction upon the arm brings the bones to their proper place, but the moment this force is relaxed the bones return to their abnormal position. Swelling exists to a considerable degree. There is intense pain on pressure and also on flexion. Treatment. — Flex the joint to a little less than a right angle and immobilize with plaster of Paris or splints. Passive motion should be gently begun at the end of a week. Union is generally ligamentous. Fracture of the Shaft of the Ulna. — The ulna is weaker below the middle than in its upper portion, and, as a consequence, fracture is most common in the middle or lower third. From its exposed and subcuta- neous position the bone is most frequently broken by direct violence and the fracture is often compound. When the radius remains unbroken the displacement in fracture of the ulna is not very marked. The arm is comparatively helpless and movement is painful. Treatment. — A plaster-of-Paris cast or a moulded pasteboard or gutta-percha splint, grasping the whole of the forearm and the ulnar side of the hand, is sufficient in ordinary cases. When the displace- ment is angular and the fragments approach the radius, the treatment must be the same as when both bones of the forearm are broken. A practical point worth bearing in mind is that when the forearm is car- ried in a sling the pressure falls upon the ulna and tends to displace the fragments toward the radius. When firm splints or a plaster cast are employed the ulna is guarded against this danger. Fracture of the Radius and Ulna Together. — This fracture is readily recognized. It occurs mostly in the lower and middle thirds of each bone. The radius is, as a rule, broken higher up than the ulna. The common cause is a fall upon the hand. Muscular action is very rarely a cause. In children a partial or green-stick fracture occurs more frequently here than in any other bone. The symptoms are pain, swelling, helplessness, mobility, and crepitus. Treatment. — In green-stick fracture the child should be placed under an anesthetic if necessary, and the bone straightened. When the frac- ture is complete, traction is employed and the fragments adjusted by direct manipulation. When the fracture is in the upper third of the radius and above the insertion of the pronator radii teres, the biceps supinates the upper fragment. This must be corrected by putting up the forearm in the supine position ; otherwise the power of supination in the limb will be lost. Another mishap to be avoided is the tendency of the bones to approach each other. When the reduction has been effected deep pressure should be made by the fingers before and behind to ensure separation of the bones. The best retentive apparatus is an INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. "JT, anterior and posterior splint a little wider than the diameter of the arm, and carefully padded down the center to keep the bones apart. The splints are made wide, so that when the bandage is applied it exerts no lateral pressure. The forearm must be carried midway between pro- nation and supination. A notable and expensive lawsuit occurred a few years ago for the alleged reason that the doctors neglected the maxim " thumbs up." For the first week the limb should be frequently examined, and the bones separated should they show a tendency to approximate. At the end of the second week a light plaster-of-Paris cast can be applied. Passive motion (pronation and supination) should be commenced about the end of the third week. In this fracture, as well as in all other conditions requiring immobilization of the forearm, care must be taken to apply the bandage while the elbow is flexed. If applied in the ex- tended position and the limb be afterward flexed, the bandage is thereby tightened and there is a danger of gangrene. Another risk run in this accident is that the radial and ulnar arteries are readily compressed by the displacement of fragments of bone. Fracture of the Radius Alone. — The head of the radius is fractured mainly as a complication of dislocation of the elbow. Frac- ture of the neck has been observed in a few cases. The injury is de- tected by the examiner placing his fingers on the head of the radius and rotating the forearm, when it will be found that the head does not move with the rest of the bone. Additional evidence of the fracture is gained when pronation and supination are lost and when pain is felt at the seat of the injury by movement of the hand in either direction. Trcatmoit. — A rectangular splint with a firm pad over the front of the forearm ; passive motion about the third week. Fracture of the Shaft of the Radius Alone. — The pronator radii teres is inserted into the rough ridge in the middle of the outer surface of the bone, and plays an important part in fracture of the shaft. When fracture takes place above the insertion of this muscle the upper fragment is displaced by the supinator brevis and the biceps, and the lower fragment by the pronators ; consequently, the relative position of the radius and ulna is not the same above and below the seat of injury. When the bone is broken below the line of the inser- tion of the muscle, the upper fragment is but slightly, if at all, dis- placed, the pronator radii teres holding it in position ; the lower frag- ment, however, is tilted inward toward the ulna through the action of the supinator longus and the pronator quadratus. Symptoms. — There is but slight displacement so long as the ulna remains intact. Other convincing signs, however, are not wanting. There is pain over the seat of the injuiy. Grasp the forearm just above the wrist and rotate, and you will find that the upper part of the radius does not move with the rest of the bone. Crepitus can be felt and pronation and supination are lost. Treatment. — When the fracture is above the insertion of the pro- nator radii teres, the arm should be put up in a position of complete supination. The upper fragment is in this position already, and we cannot change it ; so we put the lower fragment in the same form, thus bringing them into line. This is all very well in theory, but the posi- 74 SURGICAL DIAGNOSIS AND TREATMENT. tion is a trying one, and patients can seldom be induced to submit to it. Lying in bed with the arm fully extended and the palm upward will serve the purpose. Or a rectangular splint may be applied to the pos- terior aspect of the arm and forearm, the limb being carried in a sling with the elbow drawn back, so that the middle of the forearm is at the lateral middle line of the body. When the fracture is below the insertion of the pronator radii teres the indication for treatment is to prevent the upper end of the lower fragment from being drawn inward. This might result in union with the ulna, and as a consequence the loss of power to pronate or supi- nate. Straight, flat splints wider than the diameter of the arm are to be applied back and front, with carefully formed interosseous pads, and the arm carried in a sling " thumb up." The hand should be un- supported. Fracture of the Lower End of the Radius, or Colles's Frac- ture. — With the single e.xception of the clavicle, this is the most common of all fractures. A person thrown from a carriage or running Fig. 20. — " Silver-fork " deformity of Colles's fracture, photographed half an hour after the accident (Keen and Wliite). and falling forward instinctively puts out his hands to save himself The weight of the body thus comes upon the wrists. A tremendous strain is thrown upon the joint ; something has to give way, and it must be either ligament or bone. Clinical evidence has shown that when it comes to a contest between ligament and bone, the bone must yield. In this case the radius is the bone to suffer, and it breaks about one inch from its low^er extremity. The accident occurs at all ages, but is more common in advanced life. The direction of the fracture is usually transverse, and it is generally impacted. It may be oblique, and the obliquity may be in either direction. The displacement most generally met with is that of the lower fragment driven backward. Examination. — The accident happened by a fall forward or from a height upon the hand, which received the weight of the body. When the force came upon the bone the forearm was nearer a vertical than a horizontal position. The patient carefully nurses the wrist on the palm of the other hand. Pain is felt at the lower end of the radius. The wrist and hand are helpless. A marked and peculiar deformity is INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 75 apparent, which resembles a " silver fork" (Fig. 20), and is so called. Look at the dorsum of the forearm and wrist. The back of the hand appears strangely long. Just above the carpus is a prominence. This is the lower fragment driven backward. Immediately above it is a depression, because the lower fragment is not in line with the upper. Next examine the palmar surface. Just above the carpus is a depres- sion where the lower end of the radius would be if it had not been driven backward. Immediately above this is a prominence which is the lower end of the upper fragment. Stand at the patient's elbow and look toward the hand, and the appearance is very remarkable. The hand is drawn toward the radial side, for impaction and displacement have shortened the radius. The ulna looks as if it were about to come through the skin. The fingers are flexed. Pronation and supination are impossible. To find the line of separation make firm pressure along the outer border of the radius. It will be found from one-third to three-fourths of an inch above the articular edge. Errors. — Do not mistake this for a severe sprain. A sprain cannot show the same deformity. The patient may think he has a dislocation of the wrist. A dislocation of the wrist is a very rare accident, and cannot be confounded with this fracture except by the careless or uninformed. Treatment. — Reduction is difficult, owing to the impaction, which must, in all cases, be relieved. Grasp the patient's hand with yours as in the act of handshaking, make strong traction, and bend the wrist at the same time toward the ulnar side. If this fail, place the wrist in forced extension, and, while the hand is drawn upon, push the fragment into place by direct manipulation. It is of the utmost importance to the after-appearance of the limb that the posterior displacement should be fully corrected. When once the fracture is reduced there is no danger of its being again displaced, and on this account the matter of splints is of minor importance. When preferred, the posterior splint may end at the wrist : the anterior one may end at the same level, or may be carried to the palm with a pad at its lower end, over which the fingers may rest or grasp. A plaster-of-Paris dressing is often employed, but excellent results are obtained by using no splints at all. A band of adhesive plaster about the wrist gives support and allows motion of the fingers from first to last, which is a very important point. When the anterior or posterior lip of the radius is broken off it is known as Barton's fracture. Fracture of the Metacarpal Bones. — These bones are broken by direct violence, as in fistic encounters. The displacement is slight, and crepitus may be wanting. The diagnosis is made by pain on pressure and by pressing the corresponding finger upward. Treatment. — A palmar splint, well padded, to correspond with the natural concavity of the metatarsal bones. Fractures of the phalanges are usually compound and the result of direct violence. The diagnosis is easy, as the usual signs of fracture are present. The treatment consists of the application of small palmar splints well padded. Fracture of the Pelvis. — Serious injuries are often met with yd SURGICAL DIAGNOSIS AND TREATMENT. about the pelvis. They may be caused by a loaded wagon running over that part, or by the fall of heavy bodies, such as timber, rock, or earth, or by the pelvis being crushed while in the act of coupling railway cars, or by the kick of a horse. It is puzzling, even to the most experienced, to discover exactly the extent to which the parts have suffered. In all cases of this kind there are contusion and pain. Fright often plays a prominent part, for the terrible sensation of feeling that he is about to be crushed to death is sufficient to put an ordinary person into a condition approaching collapse. The pelvis is strong, and so constructed that it can resist a great force or bear an enormous weight, but it has its weak points. The injuries for which we must be on the lookout in accidents occurring in the manner described are — P'ractures of the pelvic bones ; Separation of the symphysis pubis ; Rupture of the urethra ; Rupture of the bladder ; Injuries of the abdominal viscera. The Pubic Bone. — A crushing force may fracture this bone. The line of fracture runs through the upper ramus, just inside the ilio- pectineal eminence, and through the lower ramus near its junction with the ischium. Besides giving way in front, the pelvis may give way posteriorly, either in the ilium behind the acetabulum or in the sacrum, or partly in either bone and partly in the sacro-iliac synchon- drosis. Instead of fracturing the bone, the force may cause separation of either the pubic or sacro-iliac symphysis, or both. From a clinical standpoint this is equivalent to a fracture. Symptoms. — The displacement is sometimes very marked, not only to the touch, but to the eye. In the absence of this evidence we rely upon pain under direct pressure or when movement is made by grasp- ing the wing of the ilium. If blood escapes from the meatus, we know the urethra has been injured. A catheter may be passed, and if no urine escapes, then the bladder is ruptured. This, however, may be the case where there is no pelvic fracture : the same accident may happen from a kick on the abdomen, especially when urine has not been voided for some time before the injury is inflicted. The patient is unable to raise the leg from the bed. Treatment. — Immobilize the pelvis by a firm, broad girdle or plaster- of-Paris cast. When double vertical fracture exists, employ Buck's extension upon the limb as in fracture of the femur. If the fracture is compound, see that drainage is perfect and asepsis maintained. Rupture of the urethra will probably require perineal section. The Sacrum. — Fracture of this bone is rare. The direction is usually transverse, and it is always the result of direct violence. Common complications of the injury are paralysis of the rectum, the bladder, and the lower limbs. The displacement is angular, and cor- rection is made by pressing the coccyx forward. The coccyx, when fractured, presents the same symptoms as dislocation of the bone, and requires the same treatment This injury is almost invariably fatal, as the sacral plexus of nerves is involved. The Coccyx. — Fracture of this bone is more often met with than the last named, the result of falls, kicks, or gunshot wounds. Neur- INJURIES AND DISEASES OE THE OSSEOUS SYSTEM. 77 algia of the coccygeal nerves is often present, due to pressure upon them. The pain is continuous, and is called coccydinia. Treatment. — The same as that for fracture of the pelvis. The addi- tion of a V-shaped strip of adhesive plaster to hold the bone steady may often be found beneficial in relieving the pain. The Ischium. — A fall upon the buttock may fracture the tuber- osities or the entire bone. The Ilium. — A crushing force may break off the crest of the ilium. Muscular action or direct violence may fracture the anterior superior spinous process. The posterior inferior and the posterior superior spinous processes may be broken by direct violence. The fracture is recognized by the presence of a movable fragment with crepitus. Treatment. — In all these injuries the pelvis must be immobilized and the patient kept quiet in bed. Complications must be treated on general principles. Fractures of the Femur. — The Neck of the Femur. — When Fig, 21. — Fracture of the small part of the neck of the femur (Stimson). Fig. 22. — Fracture at the base of the neck of the femur, with spHtting of the great trochanter (Stimson). called to an old person who has fallen, be it in ever so simple a way, and who suffers pain at the hip, be on the lookout for fracture of the neck of the femur. A misstep or tripping over a slight obstacle such as a mat, or even an attempt to prevent a fall, is sufficient to cause this frac- ture in elderly people. The young and middle-aged, however, are not exempt, but in them a greater force is necessary to break the bone. It is more common in women, as is Colles's fracture. The old classification of this calamity was into extra- and intra- capsular fracture. This does not cover the ground, for many of the cases partake of the characters of both divisions. It is better to speak of fracture at the small part of the neck (Fig. 2i), and fracture at the base of the neck (Fig. 22). The practical difference between these two is this : In fracture at the narrow part of the neck impaction rarely takes place, and bony union is possible, but not probable. In fracture at the base of the neck impaction is the rule (often with rotation out- 78 SURGICAL DIAGNOSIS AND TREATMENT. ward), and bony union is the rule. The symptoms of both are the same. Exauii)iatiou. — The patient hes in bed or on the spot where he fell, complaining; of great pain at the hip, particularly when any attempt is made to move him. In some cases, however, the pain is slight, and the limb can be raised from the bed. This is where there is impaction. It is possible also for the patient to walk. The rule, however, is that the limb is helpless, and as it rests straight upon the bed and you compare it with the other limb, the foot is seen to be everted. If the foot is not everted, you will find the patient cannot evert it as well as he can the uninjured member. Impaction must be taken into account, for if this occur with the limb in the posi- tion of inversion, the foot will remain in that position. The thigh at its upper part has an unusual fulness and roundness. Pushing the limb upward from the ankle or knee produces pain, as also does pres- sure upon the neck or the trochanter. Pressure over the neck of the bone in front shows that the tissues cannot be so easily depressed as they can upon the other side. Measure the limb from the anterior superior spinous process to the outer malleolus, and the injured limb will show a shortening of one-fourth of an inch to two inches. To prove that the shortening is at the neck, apply Nekton's measurement as follows : From the anterior superior spinous process to the tuberosity of the ischium. The trochanter on the injured side occupies a higher position in reference to this line than does its fellow of the opposite side. Bryant's line can next be used — viz. around the pelvis from one anterior spine to the other. The distance from the tip of the trochanter to this line will be found shorter on the injured side. These cases are fruitful sources of malpractice suits, for it has often happened that the evidence of fracture was obscure ; the patient was disabled, but the injury was supposed to be only severe bruising. Do not run any risk, but treat it as a fracture if you are in any doubt. Signs of Impaction. — The foot is everted, the leg is shorter than normal, pain is localized, and there is marked flattening of the trochanter on the impacted side. When these conditions are present, crepitus should never be sought for. Treatment. — Union in old and enfeebled persons is doubtful. Should they show the bad effects of confinement to bed, we must make the treatment of the fracture a secondary matter and attend to their general health. Traction should be employed gently, and impaction, if exist- ing, should not be disturbed. Make the patient as comfortable as possible, and guard against bed-sores. Sand-bags or cushions may be used to steady the limb, or a plaster-of-Paris cast to include the whole limb and the pelvis. Buck's extension, with a five-pound weight, will allow the patient to sit up in bed, and will keep up just enough trac- tion to make him comfortable. Fracture of the great trochanter may occur as a result of direct violence. The line of fracture falls outside the joint, and the patients are able to walk, notwithstanding the injury. The diagnosis is made by the existence of localized pain and by the presence of a fragment which moves independently of the shaft of the bone. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 79 The trcat)ncnt is immobilization and rest. If the fragment be drawn upward by muscular action, a bandage accurately applied will overcome this tendency. Fracture of the Shaft of the Femur. — This is a fracture which answers all the characteristics of fractures in general. It may be pro- duced by any of the ordinary causes of fracture — direct violence, indirect violence, or muscular action. The direction of the line of fracture is usually oblique, but in children it may be transverse (Figs. 23. 24). Symptoms. — As the patient lies in bed the limb shows more or less deformity. The muscles are bunched up and the thigh is shortened. The fragments usually o-verlap, and this displacement is increased by Fig. 23. — Transverse fracture of the shaft of the femur immediately beneath the trochanter. Fig. 24. — Fracture of neck at junction with head. the contraction of the muscles. The foot falls outward in eversion, simply from its weight. When an attempt is made to lift the limb intense pain is felt and abnormal mobility is apparent. Crepitus is readily detected, but the other symptoms are so clearly evidences of fracture that this symptom is unnecessary. Measurement from the anterior superior spinous process to the outer ankle shows shortening. Bryant's and Nelaton's measurements prove that this shortening is not at the neck of the femur. When the hand is passed over the seat of fracture and the limb is gently raised, the abnormal mobility is appar- ent. Grasp the thigh gently, rotate the limb below, and you will find that the upper portion does not share in the movement of the lower. Treatment. — Make steady traction until the shortening is overcome. Should a fragment of the bone pierce the muscle and skin, flex the thigh upon the pelvis and the leg upon the thigh. This will relax the muscle and the fragment will return to its place. Traction contin- 8o SURGICAL DIAGNOSIS AND TREATMENT. uously maintained in one form or other is the best treatment, and the most satisfactory mode of traction is Buck's extension. The extending force is a weight suspended by a cord which passes over a pulley. It is applied in the following manner : Take a strip of strong adhesive Fig. 25. — Adhesive plaster cut for Buck's extension (Stimson). plaster four inches in width and long enough to reach from above the knee down the limb, around the sole of the foot (where it is left loose), up the other side, opposite to the place of beginning (Fig. 25). A piece of wood five inches by three inches, with a perforation in its center, is "V :x Fig. 26.— Adhesive plaster folded for Buck's extension (Stimson). placed opposite the sole of the foot, and the adhesive plaster attached to it by folding its edges over the wood (Fig. 26). Through the open- ing in the wood a stout cord is passed, and a knot tied upon it to pre- vent its being pulled back by the weight. The foot and lower third of Fig. 27. — Buck's apparatus with Volkmann's sliding rest for fractures of the thigh. the leg are next bandaged by a roller bandage ; over this the adhesive strips are applied and attached to the sides of the limb as far as they reach up the thigh. The bandage is continued upward over the plasters, thus supporting them against the limb. The cord is next carried over a pulley attached to the foot of the bed, and a weight varying accord- INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 8 1 ing to circumstances is attached to its free end. The weight should run about a pound for each year of age from five to twenty. To provide for counter-extension the foot of the bed is raised. To pre- vent outward rotation the most convenient appliance is Volkmann's sliding rest (Fig. 27). It is formed of two side-pieces eight inches apart and two feet in length. They are united by two cross-pieces, and on these rest a posterior splint and foot-piece. To this splint the leg is attached. Various other methods of treating this fracture are in vogue, such as Cripp's splint, Nathan R. Smith's anterior splint, which is an improvement on the old double inclined plane, and Hodgen's splint, which combines the principle of the double incHned plane and Buck's extension. The two latter methods are of great advantage when the fracture is just below the insertion of the psoas and iliacus, and counteract the bad effect of tilting forward of the upper fragment, which is common in fractures at this part of the femur. Fractures of the Lower End of the Femur. — Fractures at the lower end of the femur bear a close analogy to those at the lower end of the humerus. The bone may be broken above the condyles (supra- condylar). This fracture may be complicated by another at right angles to it and running into the joint, a T-shaped fracture ; one or other of the condyles may be detached, and lastly the epiphysis may be separated. The lower end of the femur may be split by the wedge- like action of the patella. Supracondylar and T-shaped Fracture. — The direction of a frac- ture just above the condyles is generally oblique, and the especial danger is that one of the fragments may injure the popliteal vessels. The obliquity is generally from above downward and forward. The lower fragment is rotated by the gastrocnemius, and its fractured sur- face is directed backward. If while the fragment is in this position any traction be made upon the leg, the vessels are almost sure to be injured. When the displacement is in the opposite direction — that is, with the lower fragment projecting forward — the vessels are exposed to danger from the pressure of the lower end of the upper fragment. Diagnosis. — The pain and deformity, if any, are lower down toward the knee than in other fractures of the shaft. Shortening is usually apparent. Even with impaction the symptoms are easily recognized. When the fragments are free, abnormal mobility and crepitus add addi- tional testimony. Grasp a condyle in each hand, and if the fracture is T-shaped the condyles can be moved backward and forward upon each other. Besides this, they are spread apart, giving the appearance of a greater width to the lower end of the femur. When the joint is involved another important sign is observed : the synovial cavity becomes distended with blood. If you find the popliteal space rapidly filling up and an immense swelling forming, and, in addition to this, the leg becoming cold and pulseless, you may know that the popliteal artery is torn and bleeding profusely into the tissues. When the artery is simply pressed upon, the limb also becomes cold, but this takes place gradually, and the swelling in the popliteal space is wanting. Treatment. — This must vary according to the conditions present. Be careful in making extension lest the vessels become pressed upon 82 SURGICAL DIAGNOSIS AND TREATMENT. or torn. Gentle traction with direct manipulation is generally safe. When the upper fragment projects backward, Buck's extension is a suitable dressing. When the lower fragment has a tendency to back- ward displacement, the gastrocnemius is the disturbing element which must be disposed of This can be done either by dividing the tendo Achillis or by treating the fracture on a double inclined plane. In general, a plaster-of-Paris cast, with anterior and posterior coaptation splints under the plaster, will fulfil all the requirements. When the knee-joint is involved, the effusion and swelling must be got rid of by pressure, cold applications, and, if necessary, by aspiration. Passive motion of the joint should be begun not later than the end of the fourth week. Laceration of the popliteal vessels is a very serious complication. When it occurs a tourniquet should be applied to the femoral artery, the vessel cut down upon and tied above and below. The vein should receive careful attention, as it may be injured as well. In this event amputation is the only treatment. Fracture of the Patella. — A fall upon the knee, or a fall or blow combined with a strong effort on the part of the patient to save himself, is likely to cause fracture of the patella. The direction of the fracture is generally transverse. The line may be across the middle or near the upper or lower end. Sometimes it is stellate or star-shaped, and in rare cases it is split from top to bottom. An oblique fracture is very rare. When caused by direct violence the fracture is often either compound from the first, or it may become so at a later period by sloughing of the soft parts covering the bone. When the fracture is transverse the upper fragment is drawn upward by the action of the quadriceps, and a gap exists at the seat of fracture. It fortunately sometimes happens that the periosteum remains intact, and thus little or no separation takes place. Symptoms. — After such an accident (a fall upon the knee, a blow, or struggle to avoid falling) pain is felt over the patella, and the patient cannot extend the leg. The fragments are independently movable, and a distinct transverse gap exists between them, which can be closed up by moving the fragments toward each other. Treatment. — If the periosteum has not given way and there is little or no separation, a plaster-of-Paris cast from the ankle to the upper third of the thigh is a good dressing. With wide separation something more than this is necessary. A long list of appliances might be named to meet the requirements of these cases. A posterior splint is applied, and by oblique turns of a roller bandage the fragments are maintained in their proper position. The patient must keep his bed with the foot raised, thus counteracting the action of the quadriceps extensor tendon. A very useful and easily constructed appliance is Agnew's splint (Fig. 28). A piece of board thirty inches long, five inches wide at one end and four at the other, is slightly hollowed out to fit the thigh and calf, leaving the middle plain to correspond with the flat surface behind the knee. Four pegs are fitted into the sides in such positions as to give attachment to the bandage which draws the fragments together. The method of its application is seen in Fig. 29. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 83 Should the above methods fail or should it be found impossible from the first to keep the fragments in apposition, operative measures should be resorted to. Sev^eral operative procedures have from time to time been employed — for instance : 1. Open arthrotomy, with suturing of the fragments with silver wire. This has been very successful in a large number of cases. It has led to suppuration and fatal results have been reported. Under strict antisepsis and in healthy subjects the risk to be run need not be considered great. The operation consists in making a free incision across the patella to expose the fragments. If the fracture is an old one, the broken surfaces must next be freshened. Any fibrous tissue which has recently formed, or any fascia or other tissue which has come between the fragments, should be carefully removed. Holes are drilled into the bone by directing the drill through the anterior surface of each fragment obliquely from the attached border toward the poste- rior edge of the fractured surfaces. Three sutures of silver wire are sufficient, and when perfect approximation has been effected the ends of the wire are cut off, and either hammered into the bone or left pro- truding from the wound to be withdrawn later. 2. Subcutaneous suture has proved satisfactoiy and is easily per- FlG. 28. — Agnew's splint for fractured patella. FiG. 29. — Agnew's splint applied. formed. The method is as follows : After thorough disinfection of the limb a long, half-curved Hagedorn needle, carrying a strong silk suture, is inserted at one side of the ligamentum patellae, and carried through the ligament to the corresponding point on the other side ; the needle is then reinserted at the latter point, and carried up along the edge of the fragments to a point above the patella, then through the tendon of the quadriceps to the corresponding point on the other side, and back to the place of beginning. The fragments are now accurately approximated by means of tenacula, the suture drawn tight, tied, the ends cut off, and the knot pushed beneath the skin. The knee is dressed antiseptically, and placed upon a posterior splint for one week, after which a plaster-of-Paris cast is worn for a month constantly, and for another month during the daytime. Barker's operation is probably an improvement on the ordinary subcutaneous suture. The method of operating is as follows: With the finger and thumb of the left hand steady the lower fragment, and at its lowest point in the middle line of the ligamentum patellae make a small incision by means of a narrow-bladed knife through the skin and into the joint. Through this opening a stout-handled pedicle-needle is passed into the joint behind both fragments. The upper fragment is now pushed down as closely to the lower as possible, and the needle thrust through the quadriceps tendon at the upper edge of the frag- ment. The point of the needle, becoming apparent beneath the skin, is 84 SURGICAL DIAGNOSIS AND TREATMENT. cut down upon and pushed to the surfece. A stout silk thread is passed into the eye of the needle, which is withdrawn, carrying the thread behind the fragments (Fig. 30). The end of the thread is withdrawn from the needle's eye and left emerging from the lower opening. Again the needle is passed through the lower opening, but this time it is made to pass in front of both fragments and out at the upper opening. It is threaded with the upper end of the silk and withdrawn, leaving the thread in front of the fragments (Fig. 31). The fragments are approx- imated and rubbed against each other to displace clots ; the ligature is securely tied, cut off short, and the wounds closed. The bone unites, in the great majority of cases, by fibrous tissue, and on this account the after-treatment is more important in this fracture than perhaps in any other. Although the separation of the fragments may, at the outset, be to the extent of only half an inch, it is not uncommon to have this distance increase until, at the end of several months, it may Fig. 30. — Barker's operation for transverse fracture of the patella (first stage). Fig. 31. — Barker's operation for transverse fracture of the patella (second stage). reach five or even six inches. This may be explained in two ways — either that no union has taken place at all, or the newly-formed fibrous tissue has been stretched by allowing the use of the knee at too early a period. In all cases of transverse fracture perfect immobilization of the knee should be maintained for eight weeks, after which an apparatus should be worn to prevent flexion for six months. The stiffness in the knee resulting from such long-continued disuse passes off gradually, and the fibrous tissue becomes so firm that it will not stretch. Fractures of the Leg-. — The weakest part of the tibia is at the junction of the middle and lower thirds, and here it is most frequently broken. When both bones are fractured the fibula gives way higher up. Comminuted fracture is common even when the cause is indirect violence. The tibia, for a considerable portion of its length, is covered by little more than skin, and on this account it is specially liable to INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 85 compound fracture. When both bones are broken by direct violence, it is generally on the same level and the direction is transverse. When the violence is indirect the fracture is oblique and the fragments are pointed. Beware of letting a patient attempt to walk when there is suspicion of such a fracture, for there may be no apparent deformity until his weight comes upon the limb. Then the oblique fragments slip past each other, and, perforating the skin, a compound fracture is the result. Symptoms. — Deformity is generally so clearly marked as to be apparent at the first glance. Pain is a prominent symptom, and is greatly intensified on the slightest pressure. If the patient has to be moved from the scene of the accident, be careful to secure the limb, lest the skin give way. A pillow placed lengthwise under the leg and tied around with several handkerchiefs makes a very soft and easy applicance, while firmness can be given by placing strips of lath, shingle, or similar pieces of wood at each side and behind. Treatment. — A fracture-box slung from a cradle is a very comfort- able apparatus for this fracture, but the most convenient of all is a plaster-of-Paris cast. The form known as the Bavarian splint makes an excellent dressing. It is thus employed : Take two pieces of flannel (coarse house flannel is the be.st) long enough to reach from the popliteal space to the balls of the toes, and three inches wider than the circumference of the limb ; sew them together down the middle line for the length of the leg ; for the remainder of their length they are cut in two, to be applied to the foot. Place the leg upon the flannel, so that the seam runs down the back and ends at the heel ; fold the inner layers over and fasten them together down the front. Keeping the foot exactly at a right angle, fold the end-pieces over it. Now place the leg upon one side and you are ready for the plaster. The plaster should be mixed to the consistence of cream. Spread over the inner layer from the seam behind to the place where it is folded in front, and press the outer one down upon this before it has time to set. As soon as this has become firm turn the leg over and repeat the proceeding upon the other side. When the plaster has properly set undo the fastening in front ; you now have two side-splints admirably moulded to the leg and united by a hinge formed by the seam at the back. All that remains now is to trim off the edges and fasten the inner layer down to the outer on the surface of the splint. Fracture of the Tibia Alone. — The only difficulty in diagnosis of fracture of the tibia alone is when the bone is broken transversely, and where the swelling prevents our feeling the crest. Under other circumstances fracture of the tibia is readily diagnosed. The inner malleolus may be broken, the tubercle torn off by the action of the quadriceps, and the spine or the head of the bone broken off or split by the action of the crucial ligaments in violent twists of the knee. False joint is liable to occur in fracture of this bone if the patient has been attempting to walk or if complete immobilization of the fracture has not been maintained. Fracture of the upper end of the tibia is often transverse, and when so is the result of direct violence. The soft parts are contused. The fracture may take the form of a T inverted, the vertical part extending into the joint, causing synovitis. The frag- 86 SURGICAL DIAGNOSIS AXD TREATMENT. ments may be separated by a blood-clot which may extend into the synovial sac. Tiratiiicnt for Fracture of this Form. — Apply cold compresses to remove effusion and swelling. The leg should be put up in the double inclined plane, care being taken not to have the incline too acute, as the upper fragment may protrude through the skin, thus creating a compound fracture. When the joint is not implicated a plastcr-of- Paris bandage will suffice. If there are good reasons for keeping the leg uncovered, then one splint (Cline's) on the inner side of the leg will do, as the fibula when intact will serve as a splint on the external side. Fracture of the Fibula Alone. — This is sometimes called the "railroad fracture" or "street-car" fracture, because it is so com- monly caused by jumping from a vehicle in motion. When a person jumps from a rapidly-moving street-car, and comes forcibly upon his feet with the toes pointing at right angles to the line in which he was moving, a severe strain is thrown upon the fibula. Either the lateral ligaments of the ankle or the bone must yield, and, as usual when a contest between ligament and bone occurs, the bone is found to be the weaker structure and is forced to give way. The bone may also be broken at any part by direct violence and by violent contraction of the biceps muscle. Diag)iosis. — Wlien the fracture is at the upper end it is due to muscular action, except when caused by direct violence. The displace- ment, if any, is a drawing upward and backward of the upper fragment by the biceps. Fracture in this part of the bone is of interest, owing to the liability to injury of the peroneal nerve either at the time of the accident or later by being caught in the callus. This complication is recognized by pain along the nerve or paralysis of the peroneal group of muscles. When the shaft is broken the displacement is angular and the fragments overriding, with the lower end of the upper fragment forward. The prominent symptoms are pain and tenderness at one particular spot. Mobility is difficult to recognize, and crepitus often impossible. To examine the bone press alternately with the thumbs side by side over the seat of injury or forcibly twist the foot. In this way mobility and crepitus may be found, and, even if they are not, the loss of the natural spring of the fibula will be wanting. Instead of springing back to its place, it will yield before the pressure. The weakest spot in the fibula is two to four inches above the ankle, and this is the commonest seat of fracture. To this special form the name of Pott's fracture is given. Forcible eversion and abduction or in- version and adduction will produce it. In the typical Pott's fracture three separate lines of fracture exist : first, the fibula, two to four inches above the upper part of the malleolus ; second, the inner mal- leolus ; third, the outer lower edge of the tibia. The prominent symp- tom is the displacement of the whole foot outward, carrying with it the external malleolus, which is thus separated from the fibula. The internal malleolus is thus rendered very prominent. Three points of localized pain can be found, corresponding to the three lines of fracture above mentioned. The skin over the inner malleolus is stretched, and may even be perforated by that bony point. The foot moves too freely from side to side in the space between the tibia and fibula, which is INJURIES AND DISEASES OF THE OSSEOUS SYSTE.^f. 8/ now greatly widened. In some cases the foot slips backward, so that the body of the astragulus lies behind the tibia. Treatment. — For fracture of the upper end all that is needed is immobilization with the knee flexed in order to relax the biceps. In the shaft any displacement must be reduced by traction and direct manipu- lation. Immobilization by a Volkmann's splint for a day or two, and then by a plaster-of-Paris cast, will give good results. Pott's fracture requires particular care, for the displacement is greater and the deformity is more liable to return than in any other fracture of the fibula. Grasp the leg firmly with one hand and the foot with the other. Draw the foot forward and inward until the astragalus can be felt lying up against the internal malleolus. Be careful to cor- rect any backward displacement, for this is often overlooked. Dupuytren's splint has had a long and useful career in the treat- ment of this fracture. It is a lateral splint applied to the inside of the leg and extending two or three inches below the foot. A wedge- shaped pad is placed between the splint and the leg, the thick end of the wedge being a little above the malleolus. By means of a roller bandage the foot is drawn well toward the tibia, and, continuing the bandage up the leg, immobilization is secured. A neater and more steady appliance can be secured by moulded plaster-of-Paris splints. The first of these is applied along the back of the leg from just below the knee to the heel, along the sole of the foot and beyond the toes ; the second begins on the dorsum of the foot, runs obliquely to the outer side under the sole, and up the inner side of the leg. Circular turns secure the splints just above the ankle and below the knee. Care must be taken to keep the foot in good position while the plaster is setting. Fracture of the External Malleolus. — An in\\ard twist of the foot will cause the astragalus to force the malleolus outward and produce fracture. It gives way about an inch or an inch and a half above the end of the bone. Diagnosis. — Tenderness and pain on pressure and when the foot is turned inward are the chief symptoms ; abnormal mobility and crepitus are not readily found. TreatnieJit. — Immobilization. Fracture of the Astragalus. — Diagnosis is uncertain, except where there is also dislocation or when the fracture is compound. If the latter, it is best to remov^e the fragments when displaced, as good results follow their removal. The calcaneum may be broken by a fall or by muscular action. When caused by the latter a fragment is broken off and carried upward by the action of the powerful muscles of the calf When caused by direct violence the fracture is generally comminuted. Have the patient kneel and then compare the heels. The injured one is flattened and broadened, and the tendo Achillis is relaxed. The treatment is massage and immobilization, with use of the limb as early as possible. The metacarpal bones, when fractured, present few difficulties. Pressure at the broken point causes pain, as also pressing of the cor- responding toe backward. In the first and fifth toes crepitus and 88 SURGICAL DIAGNOSIS AND TREATMENT. mobility are usually present. The displacement is so slight that in simple cases all that is needed is rest, with the foot elevated, and massage. Compound Fractures. The diagnosis of compound fractures presents no special difficulty. In no department of surgical practice is better judgment or more prompt action required than in their treatment. It is here that modern surgery has obtained some of its most brilliant results. In uncom- plicated cases a thoroughly antiseptic dressing converts a compound into what is practically a simple fracture. The first dressing is of the utmost consequence, for upon it depends to a \&xy great extent the success or failure of treatment. When the fracture is the result of indirect violence, or when a sim- ple has been converted into a compound fracture by niiduc movement of the fragments, there is little injury to the soft parts. In a compound fracture by direct violence there is usually bruising, crushing, or lacera- tion, which adds to the seriousness of the injury. The dressing in this form of fracture should be as carefully carried out as the details of a major operation. All instruments that are likely to be required should be disinfected ; the parts in the neighborhood of the wound should be washed and sterilized, as in any other operation. Most cases require anesthesia. The wounded tissues demand the utmost care in their purification. If plastered wdth dirt, machinery-grease, and other foreign substances, olive oil should be applied, followed by alcohol, s.oap and water, and corrosive-sublimate solution, i : 2000. Shreds of tissue or structures which cannot possibly retain their vitality should be cut away ; splinters and broken-off pieces of bone should be removed ; bleeding vessels should be ligated and all hemorrhage stopped. Bear in mind that to leave a nerve, a muscle, or a tendon unsutured is as gross a piece of negligence as to leave a fracture unreduced. Having attended to all these matters, the fracture is next in order. Before reduc- tion of the fragments can be effected they may have to be trimmed off by bone-forceps or even a portion removed by a saw. Drainage must be secured by counter-openings, if necessary, and the cutaneous wound sutured. A copious antiseptic dressing is applied, and a retentive apparatus suitable for the particular fracture. When possible, an ap- pliance which allows dressing of the wound without disturbing the splints should be employed. Plaster of Paris can be made to fulfil most indications, and suspension is also a valuable aid. If, in spite of all our care, suppuration takes place, the wound must be dressed daily, thorough drainage established, and the parts brought into an aseptic condition as speedily as possible. Amputation after Injury. One of the most perplexing questions for the surgeon to meet is "when to amputate." No rules can be laid down, for each case must be judged upon its merits. A consideration of the following points may help us : I. Is the blood-supply permanently cut off? When the main artery INJURIES AXD DISEASES OF THE OSSEOUS SYSTEM. 89 and its accompanying veins are destroyed, gangrene is sure to follow an attempt to sa\'e the limb (Fig. 32). When the artery alone is lost, the collateral circulation may be trusted to nourish the part. 2. Are the tissues devitalized ? The soft parts may be extensively cut up, and yet if they are incised wounds good apposition of the dif- ferent structures may be obtained and the part may be saved. It is different if the parts are crushed and mangled. The wheels of -a heavy railway car in running ov^er a limb not only comminute the bone, but crush the very life out of muscles, nerves, vessels, and ten- dons. The same may be said of powerful machinery. The skin may reriiain intact and show nothing more than an unusual paleness, but it soon sloughs, and, together with the deeper parts, becomes gangrenous. 3. Is it possible to prevent suppuration and septic infection ? As a rule, this question can be answered in the affirmative. A thorough purification of these parts, followed by a careful antiseptic dressing Fig. 32. — Gunshot wound of forearm ; circulation cut off (from a photograph in the collection of Dr. Lincoln, Wabasha, Minn.). with provision for drainage, will warrant us in attempting to save limbs which in preantiseptic days would have been sacrificed. In cases of doubt, therefore, we can wait a few days without exposing the patient to great risk. 4. If saved, will the limb be useful ? 5. Do the age and general condition of the patient admit of saving the limb ? In children we can attempt much more than in adults. The kidneys should receive careful attention. If the urine is of low specific gravity or contains albumin, the chances of saving the limb are very much lessened. II. DISEASES OF BONE. Inflattimation. — From a clinical standpoint the composition of bone differs from other parts in only one particular — namely, the 90 SURGICAL DIAGNOSIS AND I'REATMENT. presence of lime salts, which give firmness and hardness to the structure. The pathological changes are the same in inflammation of bone as in other tissues of the body — viz. hyperemia, dilatation of the blood- vessels, increased rapidity of the circulation followed by stasis. Lymph pours out through the walls of the vessels, the tissues become en- gorged, but swelling can take place only to a very limited degree. Pain is more acute and persistent, because the products of inflanmiation are confined by unyielding tissue, which does not allow of expansion. Pus, when formed, is long retained, because its pressure does not cause atrophy rapidly, and it cannot get to the surface as readily as is the case in soft tissues. Any one of the three structures of which a bone is composed may be the seat of inflammation — viz. the periosteum (periostitis), the bony tissue (ostitis), and the medulla (myelitis). Periostitis alone very rarely occurs, and the same is true of myelitis. The bony tissue is affected in either case. So we speak of osteoperiostitis and osteomyelitis. Inflammation is due to a variety of causes : 1. The result of injury. More or less inflammation attends every fracture. There is in this case no suppuration. 2. The presence of pyogenic organisms. The staphylococcus aureus and the streptococcus pyogenes are the germs most commonly found. They may find a portal of entrance by an open wound, by the blood- stream which carries them from a distant pus-depot, by the lungs, or by the digestive tract. The presence of these germs produces inflam- mation with suppuration. 3. A general infective disease, such as typhoid fever. 4. Special diathetic states, as syphilis and tuberculosis. These two are not attended with suppuration, but liquefaction is quite common. Osteoperiostitis. — Most of the cases of periostitis (so called) come under this head, for when the periosteum is inflamed the superficial layers of the bone are also involved. The common causes are exposure to cold and wounds or contusions. The bones which are the most superficial are those most likely to suffer, and on this account diagnosis is more simple. In no class of cases, however, are errors more fre- quently made, and the results are often serious. If the condition is not recognized and promptly treated, the periosteum becomes thickened, the vessels going to supply the underlying bone become occluded, pus or inflammatory products separate the periosteum from the bone, and death of bone follows. Prompt treatment prevents all this, and allows the parts quickly to resume their healthy condition. Diaf^nosis. — The bone most commonly affected is the tibia. When the inflammation is non-suppurative, the constitutional .symptoms are not prominent. There is always pain, and it is worse at night. Pass your fingers over the painful part : the pain is increased on pressure, and more or less swelling can be detected, giving the bone a spindle shape. The soft parts covering the bone are red and edematous. When there is suppuration there are marked fever, often chills, and severe constitutional disturbance. Treatment. — Keep the part at rest, and apply cold or warmth as the patient finds one or the other more comfortable. If the symptoms continue, puncture the part in several places with a disinfected needle. INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 9I When suppuration is taking place, lay the part freely open by an incision down to the bone and through the thickened periosteum. This should be followed by a moist antiseptic dressing. When syphilis is the cause of the disease, the constitutional treatment of syphilis should be carried out, and incisions are unnecessary. Osteomyelitis. — This is the most common form of inflammation in bone. The medulla is rarely affected alone, and hence myelitis need not be considered clinically. Both bone and medulla are simultaneously affected, and we name the condition osteomyelitis. The inflammation may be local, general, or septic. Slight injuries may produce inflam- mation of bone which ends by resolution, leaving the bone-layers unchanged. In the severer forms, and particularly in chronic inflam- mation, destruction of bone takes place. If death of bone occurs in mass, it is called necrosis ; if it is molecular, we call it caries. Septic Inflammation of Bone. — This occurs under two condi- tions. The first variety is seen in adults and is associated with an open wound. Before the days of antiseptic surgery, amputations, com- pound fractures, and many cases of open wound connected with bone were followed by septic osteomyelitis. Fortunately, these cases are now comparatively rare. After amputation in which septic infection of the bone takes place, the medulla is observed to be discolored, bleeding readily and protruding beyond the bone, so as to form a fungus-like growth. The discharge is abundant, sero-purulent, and of a very offensive odor. In very severe cases the destructive process is rapid, and the patient dies of pyemia or septicemia in two or three days. The second variety is a disease especially common in childhood. It occurs without wound or fracture, and has its starting-point at or near the epiphyseal line. The femur and the tibia are the bones most com- monly affected. Boys suffer three times as often as girls. About half the patients are between thirteen and seventeen years of age. The pyogenic germs gain access, not by an open wound, but by the vascular or lymphatic system. Diagnosis. — Although the symptoms of osteomyelitis are generally very plain, the most serious errors in diagnosis are quite common. A young adult is seized with intense pain in the thigh, and in a ver>' high fever is compelled to lie in bed. A careless practitioner may diagnose his case as rheumatism, forgetting that acute rheumatism attacks the joints, and not the shafts of the long bones, and that it is seldom con- fined to a single joint. Weeks or months later a large portion of necrosed femur has to be removed by operation. Sometimes the febrile symptoms impress the attendant to the exclusion of local con- ditions, and a diagnosis of typhoid fever is made. Another case may show marked redness of the skin, which of itself is sufficient to lead some persons to a diagnosis of erysipelas. Except in the early hours or days of the disease these mistakes are unpardonable. The syjnptonis are — 1. High fever, with or without a chill. The temperature is high from the beginning, and does not show the gradual daily increase with morning remissions so characteristic of typhoid fever. 2. Pain of a peculiar gnawing or boring character, worse at night. 92 si'NG/CA/. d/.h;\os/s and treatment. This pain is situated in the shaft of the bone near a joint, but not in the joint. Movement causes intense pain, due to the action of the muscles upon the inflamed area, and not to friction in the joint. There is ahvays sensitiveness on pressure. 3. Changes in the overlying parts. When the inflamed area is deeply seated no change in the soft parts is observed in the early stage of the disease. After several days the superficial layers of bone become affected, then the periosteum, and lastly the overlying soft parts. By this time the swelling can be observed — redness of the skin and fluctuation indicating the presence of pus. When the outer layers of bone are first affected these symptoms occur earlier. In either case delay in treatment is disastrous, for hour by hour the periosteum is being separated from the bone, and with it the nutrition of the osseous tissue is cut off Necrosis is the inevitable result. The neighboring joint is in imminent danger, for, sooner or later, the inflammatory process will extend to it, distending the capsule with effused fluid, into which pyogenic organisms may be brought through the blood-vessels or lymphatics. After the formation of pus and its evacuation through a natural opening or by incision an exploration can be made with a probe. When healthy bone is touched the probe produces a dull sound and the periosteum gives a firm and roughened sensation. Carious bone is gritty, and the probe can be easily driven into it. Necrosed bone gives a clear, high-pitched note, is usually smooth, and, if separated, the diseased portion is movable. Treatment. — There are few diseased conditions in which delay in treatment is so dangerous as here. Fomentations, iodin, cold appli- cations, and medication are delusive and a waste of valuable time. These are cases in which symptoms should not be treated. The pain may be the leading symptom, and in an unguarded moment you may give a hypodermic injection of morphin. The patient feels better for a time, but the destructive process is still going on. A high tempera- ture may induce you to give one of the coal-tar derivatives, such as acetanilid. This also is a mistake. A profuse perspiration, with a fall of temperature, may follow, but the security is such as the ostrich finds when he hides his head in the sand. The only treatment that can prove of any avail must be radical. The bone must be cut down upon, drilled, or trephined, and a free exit given to the pent-up products of inflammation. Tension once relieved, pain will soon cease. Evacuate the pus, scrape out the bone-cavity, irrigate with corrosive-sublimate solution to destroy remaining germs, and pack with iodoform gauze. The temperature will speedily fall. When the medulla is extensively diseased it is well to trephine at two or more points and scrape out the intervening tissue. It is better to take too much than too little, and the whole medullary canal of a long bone, such as the tibia, is often removed with advantage. The after-treatment consists in keeping the limb at rest on a suitable splint, securing perfect drainage, and guarding against sepsis. The constitutional and hygienic treatment consists in nourishing diet, cod- liver oil, quinin, and fresh air. Necrosis. — One of the objects of early and radical treatment of INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 93 the inflammatory process in bone is the prevention of necrosis. The stripping off of the periosteum, or the pressure produced by hyperemia and the other processes in the Haversian canals or the medulla, cuts off the blood-supply to a greater or less area of bone. This portion dies, and the process is called necrosis. It is gangrene of bone. Two or three months usually elapse before the dead portion of bone becomes detached. During this time profuse suppuration is taking place, which is a great tax upon the patient's strength. As soon, therefore, as the dead bone has become detached, or even before in certain cases, no time should be lost in removing it. The necrosed piece of bone is called a seqiicstnun, which simply means that it is separated from the sound portion. If the process is long delayed and nature has had time to make attempts at repair, more or less new bone is thrown out. This is especially the case when the periosteum and the outer layers of bone remain healthy. The new bone forms an osseous envelope around the sequestrum, and to this envelope the name involiicniui is given. It is often found to be pierced by one or more openings, due to ulceration through the periosteum and bone-layers outside the sequestrum. These openings are called cloaca. In removing dead bone these are important. Through a cloaca we can pass a probe or finger and determine the existence of a sequestrum, and by cut- ting away a sufficient area of the involucrum we can remove the sequestrum. ScquestrotojHv, or the operation for the removal of necrosed bone, is performed as follows : When the bone to be removed is in one of the extremities, the limb should be elevated for four or five minutes and a rubber bandage applied on the proximal side of the disease. Should the sequestrum present at one of the cloacje and be of small size, it may be grasped by forceps and pulled away. In most cases a free opening will have to be made by first cutting through the soft parts and then chiselling away the involucrum. The sequestrum can then be taken away as a whole or in pieces. The next procedure will be to scrape away the granulation tissue which lines the cavity. The parts are well irrigated and packed with iodoform gauze, which must be changed about twice a week, or more frequently if there is much discharge. Chronic Inflammation of Bone. — Cases of chronic inflam- mation are for the most part tubercular, pyogenic, syphilitic, or malignant, and follow a chronic course from the beginning. Chronic suppurative osteomyelitis may occur as a primary affection or it may take place at the site of a former acute attack. It has a decided preference for the long bones, and its victims are generally children and adolescents. The cancellous tissue near the extremities of the femur and the tibia is often the starting-point. The disease is generally circumscribed, and has a tendency to produce two opposite conditions, one being abscess and the other overgrowth. Abscess is liable to form in the interior of the bone, and especially in the lower end of the femur and either end of the tibia. Overgrowth is due to the constant irritation which chronic inflammation produces. The increase in the growth may be considerable, and is sometimes sufficient to cause deformity. In tubercular cases the bone may be lengthened, but shortening and atrophy are more common. 94 SCRGICAI. DIAGNOSIS AND TREATMENT. Syjuptoiiis. — I'ain is the most prominent symptom. It is of a gnaw- ing or boring character and often very severe. There is always increased pain on pressure over a Hmited area, and this sign is of great value in forming a diagnosis. The pain is worse at night. It may disappear at times, giving the patient a respite for days, weeks, or even months, to return again with its former severity. If you grasp the bone, it will be found to be enlarged. Trcatmoit. — When a case presents the characters above described there is only one thing to be done, and that is to get rid of the pus which is confined and secure drainage from the diseased area. In my collection of specimens I have a small piece of bone removed by trephine from the lower end of the tibia of a boy fourteen years of age. The portion of bone removed contained a small abscess large enough to admit the end of the little finger, and this comprised the whole of the diseased area. Recovery was rapid. When the tender point is found an incision should be made over it down to the bone. The periosteum having been separated by an elevator, the bone can be explored by a fine drill at different points. If pus is found, or even a suspicion of it, a trephine is applied and a piece removed, going well into the center of the bone. Should there still be no appearance of an abscess, the drill may be used to penetrate the walls of the trephined cavity. When pus is reached, a free exit must be given to it, and all the diseased part scraped away with a Volkmann's spoon. After thorough irrigation with i : 2000 solution of corrosive sublimate the cavity is packed with iodoform gauze and an antiseptic dressing applied. Even if no pus be found after cutting into the bone, benefit will result, for, tension having been relieved, the terrible gnawing or boring pain will cease. If the operation be done with proper antiseptic care, it will do no possible harm. Better that a mistake be made by trephining a healthy bone than that a dis- eased bone should go unrelieved. In case of doubt, trephine. Tubercular Ostitis. — The favorite situations of this form of disease are the bones adjacent to the hip-, the knee-, and the elbow- joints, and also the bones of the wrist and ankle. The progress of the disease is ordinarily slow, and in its early stages very insidious. The pain is often spoken of as " starting " in character. In some cases it is so light as to be scarcely noticed, but pressure always reveals its existence. The early symptoms may be little more than an impair- ment in the movements of the limb with rigidity of the muscles of the neighboring joint. Local elevation of temperature may be observed. Tubercular inflammation tends to the formation of fluid in the part affected. This collection is sometimes erroneously spoken of as an abscess. It contains vast numbers of the tubercle bacilli, but the micro-organisms of pus are wanting. Should such a cavity be laid open without antiseptic precautions and pus-germs find entrance, a double infection will be the result, and the most serious consequences are liable to follow. This is why the older surgeons found it so dis- astrous to open tubercular joints or psoas abscesses. The symptoms that distinguish tubercular from other inflammations of bone are — I. Atrophy of the muscles. The parts both above and below the INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 95 seat of disease become wasted to such a degree that simple disuse is not sufficient to account for it. 2. Spasm of the muscles. This is generally observed when the patient is dropping off to sleep. The muscles acquire a persistent rigidity which is very noticeable in the early stages of spinal caries and in hip-joint disease. Flexion of joints is almost sure to occur, the flexor muscles gradually overcoming the extensors until serious deformity results. Treatment. — Tuberculosis is greatly influenced by keeping the part at rest, and if adopted in the early stage of the disease immobilization may be sufficient to produce arrest of the tuberculous process. Con- finement to bed, plaster-of- Paris dressings, and suitable splints will fulfil this indication. The general principles of treatment in tuberculosis will also need to be kept in view, such as good hygienic conditions, nour- ishing food, and remedies directed to the improvement of the patient's strength. Some excellent results have been obtained by local injec- tions of iodoform, of chlorid of zinc, or of acid phosphate of lime. Clin- ical experience has shown that in most cases where arrest of the tuber- culous process has taken place the bacilli have been encapsulated by infiltration of the healthy tissue surrounding them. They have been, as it were, enclosed by a wall which they cannot break through. The object of the injections above mentioned is to produce this condition, and at the same time to destroy the vitality of the bacilli. Iodoform is probably the least irritating and the most satisfactory of this class of remedies. It can be used in a solution containing one part of iodo- form and ten of glycerin. By means of a needle long enough to reach the diseased area this fluid is injected in small quantity every three, seven, or ten days. A method of treatment has been recommended by Bier which is worth consideration. Clinical evidence having shown that tubercles do not multiply in parts supplied by too much blood, an artificial chronic congestion is secured by wearing an elastic bandage above the seat of the disease. This bandage is applied at more and more frequent inter- vals, and as tightly as the patient can bear it, until at last he is able to wear it almost constantly. When the above methods are unsuitable, or in cases where they have failed, an operation should be resorted to for the removal of the diseased area. Scraping and removal of the infected tissues must be more thorough here than in pyogenic ostitis. The walls of every sinus, the medulla of infected bone, and every suspected deposit of tubercle in the soft parts, such as the skin, tendon-sheaths, or synovial cavities, must be thoroughly scraped. When the disease extends into a joint the question of resection or amputation will have to be considered. Syphilitic Diseases of Bone.— The bones most liable to this form of ostitis are the long bones and those of the skull and the face. The frontal is the one most frequently affected of all the bones. Pain, worse at night, is an early symptom, and may even appear before the eruption on the skin. At first it has the character of a periostitis, but later smooth, firm, flat elevations about one or two centimeters in diameter can be felt ; these are tender on pressure. They yield readily to treatment, but run on for an indefinite period if let alone. lodid of 96 SURGICAL DIAGNOSIS AND TREATMENT. potassium and the mercurials act as specifics. No operative inter- ference is required. Fragilitas Ossium. — An abnormal brittleness of the bones by which they are liable to fracture on the slightest cause is known as fragilitas ossium. This condition may be congenital, the bones even in utero being fractured, and the fragility continuing until mature life, when it may cease. The disease may also be the result of debilitating conditions which compel long confinement to bed. Other causes are syphilis, malignant tumors, the early stage of rachitis, general paralysis, and tabes. Treatment. — Nothing can be done further than to guard against accident and to treat the fracture in the ordinary manner. Rachitis. — Rachitis, or rickets, is a disease of infancy and childhood having as its leading features a deficiency of lime salts in the bony framework and absorption of bone already formed. It is generally seen among the poor in crowded, unhealthy portions of cities, where Fig. 33.- -Rachitic curvature before operation. FiG. 34. — Rachitic curvature after operation. (From photographs in the collection of Dr. T. S. Roberts.) ventilation is bad and the general surroundings are unhealthful. It begins about the first or second year of life, rarely after the sixth. Its starting-point is the epiphyseal line, where there is found a deficiency of lime salts, and at the same time an increased growth of cartilage. Hence the bone is wider and thicker at this part. The child is loose- jointed, the ligaments being relaxed, and movements of the articulations frequently cause pain (Figs. 33, 34). When the spinal column is the seat of the disease one or other of the various spinal curvatures may result. Rachitic children are often hydrocephalic, and deformities of the brain are not uncommon. Symptoms. — One of the earliest indications of rachitis is perspiration about the head, particularly during sleep. The child is restless, and rolls his head from side to side on the pillow. There is constipation ; INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 97 the urine is increased in quantity and loaded with phosphates. Enlarge- ment of the epiphyseal end of the bones will be most likely to occur at the lower end of the radius and the ribs. The forehead and the frontal eminences are enlarged. The changes in the ribs produce the characteristic pigeon's breast. Teething is delayed. The anterior fontanelle fails to unite, and the want of growth results in a dwarfing of stature. Bronchitis, catarrhal affections, and pneumonia are common complications, and, in some instances, causes of death. About 90 per cent, of the cases improve under proper management. Treatment. — The treatment of this affection may be surnmed up under two words — nutrition and hygiene. Removal from crowded, ill- ventilated dwellings to the pure air of the country, sea-air, and sea- bathing are invaluable. Of drugs, the best are cod-liver oil, syrup of the iodid of iron, phosphorus, and the lactophosphate of lime. Osteomalacia. — While rickets is a disease of childhood, osteo- malacia, mollities ostium, or malacosteon is a disease of adult life. The most frequent subjects are pregnant women or those who have borne children. In men it is rarely found. Its cause has never been clearly explained. Among the causes assigned are defect of lactic acid, defec- tive nutrition, ovarian and uterine disorders, and changes in the trophic nerves. The leading feature of the disease is a progressive softening of the bones, resulting in all sorts of deformities, going on from bad to worse, and ending in death from exhaustion or from some complication, such as disease of the lungs, bronchi, or pleura. Symptoms. — Its early history is obscure. Pain is one of the most important symptoms. It occurs at a number of points of the body, and is liable to be mistaken for rheumatism. The sex of the patient and the existence of pregnancy with large deposits of phosphates in the urine should excite suspicion. When osteomalacia has advanced so far as to cause bending and deformities of the bones, no doubt can exist of the terrible character of the malady. Treatment. — The treatment is by no means satisfactory. Some cases are mild and have a tendency to remain almost stationary ; others pro- gress to a fatal termination in spite of every form of treatment. The best hygienic surroundings are indispensable, and deformity should be prevented by the use of protective dressings. Pregnancy should be avoided, as it has an especially injurious effect upon the disease. The medical treatment consists in the administration of cod-liver oil, phos- phates, and lime salts, but they produce little if any benefit. Removal of the ovaries and uterus has had some advocates, and a few cases have been reported in which there was decided benefit from the operation. Actinomycosis. — Until recent years this disease was confounded with sarcoma, owing to the fact that its microscopical structure bears a close resemblance to the round-celled variety of these tumors. It is now known to be a disease due to a specific germ. Infection usually takes place through the mouth, either from a wound or a carious tooth. It may also find a portal of entrance by way of the lungs, where, reaching the pulmonary alveoli, it sets up a broncho-pneumonia. The chief characteristic of the disease is a chronic inflammation which closely resembles that caused by the tubercle bacillus. 7 98 SURGICAL DIAGNOSIS AND TREATMENT. Syniptcwis. — An enlargement of the lower jaw or an ill-defined swelling in the submaxillary region or a nodule of the skin is generally the first symptom. The progress of the disease is slow, but steady. The lymphatics and blood-vessels are not involved until a late period. Pain and swelling are not marked until suppuration begins. Then the local and constitutional symptoms become as marked as they are in acute cellulitis or in diffuse osteomyelitis. As the disease progresses secondary deposits take place with caseous nodules and abscesses, no part of the body being exempt. To the naked eye there is nothing to distinguish the growth from sarcoma or granulation tissue. The special character of the disease must be settled by finding the micro- organisms which produce it. The granulation tissue and the pus contained in it are filled with round bodies like millet-seeds of a yellow color. The fungus itself is easily recognized by its star-hke masses of mycelium. TiratJHcnt. — When recognized early the diseased part should be thoroughly removed, and when this can be done the prognosis is favorable. Tumors of Bone. — The benign tumors of bone are exostoses, fibromata, and enchondromata ; the malignant are sarcomata and carcinomata. Exostoses are localized overgrowths of bone (Fig. 35), the term Fig. 35. — Exostosis of head of the tibia. hypertrophy being applied when the whole extent of the bone is increased in size. Their structure is the same as bone itself, and they are divided into two classes, according to their density, the ivory or eburnated and the cancellous. The ivory variety is commonly found on fliat bones, and a favorite position is the frontal sinus, where it may grow to considerable size, resulting in horrible deformity. This form is often associated with syphilis. The cancellous variety affects the long bones. Exostoses are often hereditary, and in that case are gen- erally symmetrical and multiple. They begin to grow in childhood, and their starting-point is the junction of the shaft with its epiphysis. They grow from cartilage, which is gradually converted into cancellous tissue, and generally cease to enlarge when the bone to which they are attached has reached its full development (Fig. 36). Diagnosis is easy. The tumors are painless, hard, and fixed, closely INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. 99 connected with bone, and can be readily felt or seen. Exostoses give little trouble, except under the following conditions ; when they inter- fere with the free use of a joint, especially in flexion : when by their pressure they cause atrophy or ulceration of the overlying soft parts ; or when they occur in the inner surface of the skull and press upon the brain. Even in the last-mentioned condition no serious cerebral dis- turbance may result, and the existence of a tumor may be discovered only after death. Treatment. — Where no inconvenience is caused no treatment is Fig. 36. — Osteoma growing on the under surface of the scapula (from a photograph in the collection of Dr. Graham, Washington, D. C). called for. The growth can be bfoken off if it be attached to the bone by a narrow pedicle, but in most cases it is best to cut down upon and remove the tumor. Chondromata, or Cartilaginous Tumors. — These growths are found chiefly on the extremities ot the long bones and in connection with the small joints of the hands and feet (Fig. 37). If composed of purely cartilaginous tissue, they are benign, but, unfortunately, they often contain a mixture of sarcomatous elements which places them within the category of malignant growths. lOO SURGICAL DIAGNOSIS AND TREATMENT. Chondromata occur on the surface or in the center of bone, in the former case being very easy of diagnosis, in the latter exceedingly difficult. They have a tendency to become cystic. Syjiiptojiis. — A slowly-growing tumor, elastic and firm, of less density than bone and irregular in shape, situated at the extremity of a long bone or at the small joints of the hands or feet, is suggestive of chon- droma. Pain is not present unless a nerve be pressed upon, which does not often occur. When the growth is central it cannot be diag- FlG. 37. — Lad twenty years of age with multiple chondromata (after Steudel). nosed until it has attained considerable size, and even then its nature often remains in doubt until after its removal. Treatment. — The only effective remedy is extirpation. The growth itself may be removed and the surrounding parts scraped away, or it may be necessary to remove a part or a whole of the bone to which it is attached. In some cases nothing short of amputation will suffice. Fibromata. — The commonly chosen seats of fibromata are the jaws and the base of the skull. The growth begins, as a rule, in the peri- osteum and is pedunculated. Rare cases occur in which the starting- INJURIES AND DISEASES OF THE OSSEOUS SYSTEM. lOI point is the center of the bone. A tumor composed purely of fibrous tissue is rare. With the exception of epuhs and naso-pharyngeal polypi, the tumors of a fibroid character are fibro-sarcomata. Fibromata grow slowly, have a tendency to become cystic, and often cease to enlarge when the bony skeleton has arrived at maturity. Diagnosis. — Fibrous tumors are irregular in shape, firm to the touch, but not so hard as bone, with which they are, as a rule, connected. The so-called naso-pharyngeal polyp commencing on the under surface of the sphenoid bone fills in time the naso-pharynx, the posterior nares, and the antrum. These growths are dangerous on account of their tendency to free hemorrhage. When the patient reaches the age of about twenty-five years the polyp ceases to grow and atrophy com- FlG. 38. — Osteosarcoma of femur (from a photograph in the collection of Dr. jepson, Sioux City, Iowa). mences. Unless hemorrhage is frequent and copious it is advisable to delay treatment in the hope that this favorable change may take place. Treatment. — Remove either by extirpation of the tumor alone or by resection of the portion of bone from which the growth has originated. Malignant Tumors of Bone. — Carcinoma of bone is exceed- ingly rare, and is always secondary or due to simple extension of the disease from neighboring structures. Sarcomata, on the other hand, are common, and are distinguished from all other tumors of bone by the rapidity of their growth (Fig. 38). No bone in the body is free from liability to this form of malignant dis- ease, but certain bones are especially prone — viz. the lower end of the femur and the upper end of the tibia ; that is to say, the bones on each side of the knee-joint. The jaw is also a common situation, and the I02 SURGICAL DIAGNOSIS AND TREATMENT. disease here constitutes one of the forms of epulis. Injury, such as fracture or bruising of a bone, frequently precedes the growth and must be considered an exciting cause. Sarcomata in bone, as else- where, may occur at any age, but the great majority of cases are found in early life. After forty years of age the disease is very rare. If we classify the tumors according to their histological structure, we have three varieties — round-celled, spindle-celled, and giant-celled. The malignancy exists in about the proportion of the size of the cell. The round cell and spindle cell are found in tumors of the most rapid growth, while the giant-celled neoplasms grow slowly and have fewer malignant characters. Fig. 39. — Round-celled sarcoma (from a photograph in the collection of Dr. Graham, Washington, D. C). A sarcoma is classed among malignant growths for the following reasons : (i) It infiltrates the surrounding structures. (2) The lymphatic glands become involved sooner or later. (3) It occurs in the form of secondary deposits in other parts, the lung being specially liable to this metastasis. Clinically, sarcomata of bone may be divided into two varieties, periosteal and central. Periosteal Sarcomata. — These are the most malignant of bone- tumors, being composed, as a rule, of round or spindle cells (Fig. 39). There is a special tendency in this variety to affect different organs, so that, although no sign of the disease is seen in the stump after an amputation, a secondary deposit in the lung may carry off the patient. IXJCRIES AND DISEASES OF THE OSSEOUS SYSTEM. lO- The deeper, more vascular layer of the periosteum is the starting-point. While the tumor is small the external layer of the periosteum is stretched over it, but in the course of time this gives way, the growth breaks through, and rapidly infiltrates the surrounding tissues (Fig. 40). Central sarcomata begin at the ar- ticular ends of the long bones or in the cancellous tissue of the short ones. They are not so malignant as the peri- osteal variety, and in the early stages are not easily recognized. As the tumor increases in size its pressure produces atrophy of the bone, until nothing is left but a thin shell of osseous tissue, which cracks beneath the fingers like an egg-shell. The fracture of this weakened bone from some trivial cause may be the first thing to excite suspicion of the real nature of the disease. Symptoms. — The early s)^mptoms of sarcoma are frequently obscure. Pain, which may be mistaken for rheumatism, is generally present. It is worse at night, and may be very severe. In many cases there is a his- tory of a traumatism. In a young person a rapidly-growing tumor at the seat of a newly-united fracture or in one of the bones near the Jcnee-joint must be looked upon with suspicion. The following questions may be considered : {a) Is there swelling of the bone ? If there be a periosteal sarcoma, a distinct swelling will be felt, usually along one side of the bone, fusi- form in shape, and avoiding the extremity of the bone. The swelling, in the central variety, appears at a much later period, is more globular in shape, and has egg-shell crackling when pressed upon by the fingers. It is found at the cancellous end of the bone. ip) Does the tumor pulsate ? Pulsation is a character of the central variety, and of the periosteal when connected with the flat bones. This pulsation is readily distinguished from the expansile, heaving pulsation of an aneurysm. Even should a thrill and bruit be present, they are only observed over small portions of the tumor. Pressure has little or no effect upon the size of the swelling, and pulsation in the arter>^ below is not impaired, except when the growth compresses the main vessel against the bone. The consistence of the tumor is subject to great variety. Sometimes it is hard and dense, at other times soft and fluctuating. Should spon- taneous fracture occur, followed by a tumor of rapid growth, a diag- nosis of central sarcoma could be made with confidence. Fig. 40. — Recurring sarcoma of the humerus (from a photograph in the collection of Dr. Strickler, New Ulm, Minn.). 104 SURGICAL DIAGNOSIS AND TREATMENT. In any case of doubt an exploring needle of moderate size can be thrust into the growth. If it be a sarcoma, the needle will be found to penetrate the bone, and through the cannula may escape myeloid cells or other elements which can be examined microscopically. Diagnosis. — The conditions likely to cause errors in diagnosis are — 1. Chronic inflammation of bone with necrosis. Cases of this kind are exceedingly puzzling, and no amount of care will ensure against a mistaken diagnosis. When the course of ostitis is very slow and free from pain, when there is much inflammatory thickening without the formation of abscess, and the sequestrum has formed in the manner known as " slow necrosis," the nature of the disease can in some instances be settled only by free exploration. I have known two cases in which all treatment was abandoned and a diagnosis of sarcoma made, which afterward proved to be necrosis of the femur near the hip-joint. 2. Inflammation in a neighboring joint may mask the symptoms of a sarcoma which has its seat in the cancellous extremity of a long \ \ t Fig. 41. — Acromegaly (from a photograph in the collection of Dr. T. P. Findley). bone. If care be taken to look for all the characteristics of joint- disease, mistakes are not likely to happen. The position of the limb, the pain (worse at night), and the effusion of fluid into the joint are very expressive, while the history of a tumor in the bone, beginning not at, but near, the joint, is indicative of sarcoma. 3. Syphilitic gummata. The difficulty in this case can be removed by putting the patient upon iodid of potassium for a few days. If the growth be syphilitic, it will steadily diminish. 4. Aneurysm of bone. This condition, if it ever occur, must be exceedingly rare. Tr^eatnient. — In either form of the disease the only chance of success lies in early and complete removal. If the tumor is situated on an INJURIES AND DISEASES OF MUSCLES, TENDONS, AND BURSM. 105 extremity, amputation affords the only hope. The operation should be at or above the nearest joint. In periosteal sarcoma of the femur amputation at the hip-joint is justifiable, but when the tumor involves the middle or upper third of the bone the case is practically hopeless. Recurrence of the disease will take place, either in the stump or in some internal organ, notably the lung. Acrotnegaly. — This disease, first described by Marie in 1886, is attended with a remarkable enlargement of the bones of the face, head, pelvis, thorax, feet, and hands (Fig. 41). Although the affection is of a nervous origin, the bony enlargement is a true hypertrophy, and first appears in the hands, feet, and lower jaw. The disease is generally symmetrical. There is usually freedom from pain ; the joints do not become ankylosed ; it follows a very long chronic course, and up to the present time no treatment has been found which has any effect upon the disease. CHAPTER IV. INJURIES AND DISEASES OF MUSCLES, TENDONS, AND BURS/E. The injuries to which muscles are liable are bruises, strains, ruptures, and wounds. A blow, a violent and prolonged contraction, or overuse will result in a condition known as a strain. The muscle is tender to pressure ; there is more or less swelling, stiffness, weakness, and pain, especially when the muscle is brought into action. The injury is found in groups of muscles, such as the deltoid, the pectorals, biceps, and pronator radii teres (the " lawn-tennis arm "). The adductor muscles of the thigh are affected in prolonged and severe horseback-riding. Any muscular exertion to which the individual is unaccustomed will produce it. A blacksmith can swing his hammer all day and feel no ill effects, but a man unused to such labor will find, after the first day's toil, that his arm is powerless. Treatment. — Rest and hot bathing or fomentations. Rupture. — Under a violent muscular effort or as the result of a severe blow the muscular structure may be ruptured. A few fibers may give way or the whole tnuscle may part in its continuity. The patient experiences a sudden and severe pain, perhaps attended with an audible snap, and immediately finds that the muscle has lost its power in whole or in part. On examination there will be found a depression or gap at the seat of rupture, and swelling due to extravasated blood. Sometimes the quantity of blood is so great as to produce a hematoma. At a later period there is discoloration of the skin. The function of the muscle is, of course, impaired or even lost, and this may result in permanent weakness of the limb. In debilitated conditions of the body, as in convalescence from typhoid fever, the muscles may suffer laceration from trivial causes, owing to their fibers having undergone granular degeneration. I06 Sl'RGICAL DIAGNOSIS AND TREATMENT. Treatment. — The most important point in treatment is rest in the position which most relaxes the ruptured muscle. The torn ends may- be approximated by properly applied compression. In cases of com- plete separation in healthy muscle sutures should be employed. In diseased muscle this is useless, as the stitches will tear out. Union is effected by the interposition of connective tissue, the length of the band depending upon the degree of separation. Wounds. — By accident or in the course of an operation wounds of muscle may be made, and are subcutaneous or open. The symp- toms are retraction of the divided ends and hemorrhage. The treatment consists in early and accurate approximation by cat- gut sutures. The union is commonly by fibrous tissue. Myalgia. — Pain in a muscle or group of muscles is a common ailment depending upon overuse, exposure to cold, and to a variety of causes, such as lead-poisoning or syphilis. The diagnosis of pain in a muscle or group of muscles is important. If a patient complains of pain over the deltoid, for example, and the pain is increased when he raises the arm from the side of his own voli- tion, while no pain is felt if the surgeon moves the arm and at the same time the muscles are kept relaxed, it will prove that the muscle is the seat of pain. Placing the limb in such a position that the muscles are stretched will also produce pain. Hence we have this rule : When a muscle is affected active movement produces pain, passive movement is painless ; over-extension or passive stretching is painful. Ligament- ous pain is elicited by any movement, either active or passive, that stretches the ligaments. A certain amount of passive motion can take place in a joint without stretching either muscles or ligaments, and this amount is unattended with pain. If you continue this movement and pain is then felt, it may be set down as having its seat in the ligaments. The treatment is heat, electricity, massage, and sedative applications. Myositis (inflammation of muscle) follows an injury, but, as a rule, this is unimportant compared to the effect upon other tissues. Muscular rheumatism, so called, is a form of myositis, and is often produced by ex- posure to cold. Gonorrhea is often attended by muscular pains (one of the forms of gonorrheal rheumatism), and may also be regarded as myositis. A chronic form of myositis is often observed in syphilis. It gives a wood-like hardness to the parts, and a common situation is the sphincter ani muscle. Symptoms. — The symptoms of mj^ositis are stiffness of the affected limb and pain, which is worse at night and increased whenever the affected muscles are brought into action. Constitutional symptoms, such as fever, chills, etc., are seldom present. Suppurative myositis is by no means common, except in the case of the psoas muscle. It has been observed as a localized inflammation, resulting- in muscular abscess and due to some local irritation, such as a foreign body or traumatism. Diffuse suppuration m muscles has, m a few instances, been observed. It appears to occur under the same conditions as diffuse osteomyelitis. The entrance of pyogenic- organ- isms is by a wound or through one of the mucous surfaces. Still more rare is the disease known as acute progressive myositis, which involves the whole of the muscular system and ends in death by INJURIES AND DISEASES OE MUSCLES, TENDONS, AND BURS.E. lO/ asphyxia or pneumonia. It is probably due to bacteria the nature of which has yet to be determined. Myositis ossificans (Figs. 42, 43) is a pecuHar form of muscle- FlG. 42. — Myositis ossificans, showing the ab- duction of the arms (Stephen Paget). Fig. 43. — Myositis ossificans, showing the contraction of the left sterno-mastoid, the masses of bone in the latissimi dorsi, and the extreme amount of abduction of the arms obtainable (Stephen Paget). The inflammation in which bony plates form in the muscular tissues, most common situation is the dorsal region. Permanent Shortening- of Muscle, or Contracture. — Long-con- tinued inactivity of muscles, as in the bed-ridden, is liable to result in contracture. These cases are generally of a mild character, and the muscles rapidly regain their normal condition under proper exercise. Chronic inflammation of the muscle itself, descending neuritis, and sclerosis following lesions of the cortex produce the most serious forms of permanent shortening. Trcatvient. — In the milder forms massage and passive motion usually suffice. In the severer cases tenotomy may be required. If the division of a tendon is likely to result in too wide a gap, the tendon can be lengthened, as recommended by Anderson (Fig. 44), by first splitting it in the middle line, and then sliding the ends to the proper position and suturing them. Tenosynovitis, inflammation of ten- don or thecitis, is a common affection. A favorite situation is at the wrist, due to over-exertion of the flexor tendons in workmen, such as stone-cutters and others, who use a hammer or other tool con- tinuously. Any tendon, however, may be affected. The disease occurs in three forms — acute, suppurativ^e, and chronic. The acute form is due, as a rule, to overwork. The course of the tendons is sensitive to pressure, and the overlying skin is hot and in some cases B— , L 1 Fig. 44. — Anderson's method of lengthening a tendon. I08 SURGICAL D/. I GNOSIS AND TREATMENT. reddened. I^vcry movement of tlie muscle is attended with pain. The surfaces of the tendon and its sheath become rou<;hened, and produce a crepitant sound which has been compared to the rustUng of silk. In aggravated cases the exudation not only involves the tendon-sheath, but the adjoining cellular tissue, so that the swelling may extend from the wrist down over the dorsum of the hand and up the arm to or beyond the elbow. Instead of simple serous fluid, the exudation may contain blood, and the pain, heat, and tension may be excessive. This variety may run into the chronic or the suppurative form of the disease. Chronic tenosynovitis is nearly always of tubercular origin. The tendons of the forearm are those most commonly involved. The prog- ress is slow and is attended with the formation of granulation tissue, in which can be found the tubercle bacilli in large numbers. Accord- ing to the density of this granulation tissue will be observed swelling along the tendons, firm or fluctuating. In some cases small bodies resembling rice or melon-seeds are formed in the sac, either floating in the fluid or attached to the walls. Besides cases due to tuberculosis, chronic tenosynovitis is frequently a result of the acute form of the disease. This may be due to some constitutional dyscrasia, such as gout or rheumatism, or it may be a consequence of adhesions. Long-continued disease of a limb after fracture or other injury is liable to result in such adhesions, which, if not completely broken up by passive movements, are a constant source of pain and inconvenience. Suppurative Tenosynovitis. — This is most frequently met with in the form of thecal abscess or whitlow in connection with the flexor tendons of the fingers or thumbs. It was formerly not uncommon as a result of septic infection after amputations, and also as playing a part in pyemia and septicemia. Whitlow begins generally as the result of a slight injury or wound which admits septic organisms. Having once gained an entrance, the germs follow the course of the lymphatics, which in these situations is toward the tendon-sheath, the periosteum, and the bone. The dense, resisting structure of the sheath and its tendon gives no room for expansion, and hence the intolerable pain and throbbing which characterize whitlow. Two varieties of whitlow are recognized — the superficial and the deep. The superficial variety occurs about the nails and affects one or several fingers at the same time. The subjects of the disease are delicate children or debilitated persons. In some instances it runs its course in a few days or even hours, ending in the formation of serous fluid, which is reabsorbed ; in others ulceration takes place, and the nail is undermined and eventually cast off. Deep whitlow is a much more serious affair. The palmar aspect of the last phalanx of one of the fingers is the common situ- ation. The finger becomes painful in a day or two after an injury ; then it begins to throb, particularly when allowed to hang down ; the patient passes sleepless nights ; the pulse increases in frequency and the temperature rises. Suppuration is taking place, and nothing but the evacuation of pus and the relief of tension will get rid of the suffering. Treatment. — At the \'er}^ commencement of the disease the hand may be placed for an hour or longer in a hot solution of corrosive sub- INJURIES AND DISEASES OF MUSCLES, TENDONS, AND BURS.E. IO9 limate in the hope of destroying the germs and averting suppuration. If at the end of two or three days the symptoms show no sign of abatement, the only treatment of value is free incision. When the terminal phalanx is affected the tissues should be divided down to the bone. In the case of the first or second phalanx the pus is probably no deeper than the tendon, so that opening the sheath is sufficient, and relief will speedily follow. The rest of the treatment consists in strict antiseptic dressings. Ganglion — or " weeping sinew," as some of the old surgeons called it — is a collection of fluid in connection with a tendon-sheath. Its favorite situation is the back of the hand or wrist, w^here it appears as a round, firm tumor of varying density, causing little or no incon- venience, except in such occupations as require constant use of the affected tendon. This little tumor is a cyst containing the synovial fluid, but generally changed to a jelly-like consistence. Sometimes the tendon-sheath is distended for some distance, and the fluid contains melon-seed bodies and is thick and gelatinous. This form, sometimes called compound ganglion, is found in the palm, while the simple cyst is common on the back of the hand and wrist. The causes are strains, overuse, or slight injuries frequently repeated. Treatment. — Three methods of treatment are in vogue : 1. Subcutaneous rupture. This may be effected by a quick and forcible pressure of the thumb or a smart blow. The contents of the cyst are forced along the sheath or into the surrounding tissues, and are then absorbed. The objections to this method are that the cyst rapidly refills, and it may then be so thick and strong that it cannot thus be ruptured. 2. Subcutaneous division by a small knife or flat needle. 3. Cutting down upon the cyst and excising it is the most effectual of all methods, and when carried out aseptically is perfectly safe. Compound ganglion is a serious affection, and the results of the most careful treatment are often unsatisfactory. Syme's method of freely laying open the sheath was successful in his hands even before he resorted to antiseptic surgery. The sheath should be opened above and below the annular ligament, the melon-seed bodies removed, and thorough drainage effected. Suppuration is disastrous, for it is almost sure to extend to the joint, and the tendons themselves are liable to slough. This operation should never be undertaken except under the most rigid asepsis, and in any case a guarded prognosis should be made. Dupuytren's contraction is an affection of the hand found in men (rarely in women) of middle or advanced life. Its characteristics are flexion of the fingers at the metacarpo-phalangeal joint ; the palmar fascia is tense and firmly adherent to the skin, while great resistance is felt when an attempt is made to straighten the fingers. In aggravated cases the fingers are tied rigidly down into the palm of the hand. It is generally associated with gout, but engineers, fitters, and other mechanics are liable to suffer from it. Ti'eatvient. — In the early stages massage and passive movements of the affected fingers may arrest the progress of the deformity. A splint may be worn at night, and a variety of complicated appliances have no SURGICAL DIAGNOSIS AND TREATMENT. been invented by instrument-makers. These have not been very satis- factory. When the finger is so far contracted as to form a right angle, operative treatment is necessary. Various procedures have been resorted to. Adam's method consists in subcutaneous section at many points with a fine tenotomy knife. The hand having been carefully tlisinfected and held in an deviated position for a few minutes to limit the amount of hemorrhage, incisions are made in the palm at those points where the skin is still movable over the fascia. This is continued down the fingers, each resisting point being severed until the digits can be thor- oughly extended. The small openings can be sealed by iodoform and collodion, and the hand placed immovably upon a palmar splint for three or four days. Passive motion should then be continuously carried out. In favorable cases two weeks suffice to effect a cure. Diseases of Bursse. — Between tendon and bone, over bony prominences, and in fact at any point where there is much friction, bursse exist, either congenital or acquired. They may communicate with the cavity of a joint, in which case they must be regarded as offsets of the synovial sac. In most cases they are simply cavities in the cellular tissue. Wounds of bursae, if not infected, heal rapidly. Punctured and lacerated wounds and contusions are liable to prove troublesome, owing to the friction of the adjacent structures. The treatment of such injuries is by rest, thorough cleansing, drainage, and pressure. Bursitis, or inflammation of bursse, is commonly met with in the form of " housemaid's knee," the bursa in front of the patella being the seat of inflammation (Fig. 45). The " student's elbow " is an inflammation of the bursa over the olecranon, due to pressure of the elbow upon a hard table while absorbed in study. The bursa lying between the tendo Achillis and the os calcis is another that is liable to inflammation. It is recognized by a swelling which occupies the space on each side of the tendon, and is distinguished from an effusion into the ankle, which would ap- pear in front of the joint. Bursitis may be acute, chronic, or sup- purativ^e. Acute bursitis is nearly always the result of injury. The housemaid upon her knees scrubbing floors bruises the prepatellar bursa and inflammation follows. Syphilis, gout, and tuberculosis are also regarded as causes. The early symptoms of bursitis are swelling, red- ness, pain, and pyrexia. The bursa being, in its natural state, an unfilled cavity, a certain amount of fluid can collect without pro- ducing tension ; hence pain is not an early symptom. In super- ficial bursae diagnosis is easy, but in the case of deep bursae it may be difficult. Here we have little or no swelling to guide us, and our reliance must be placed upon our knowledge of the action of the mus- cles. Inflammation of the bursa under the deltoid is recognized from Fig. 45. — Prepatellar bursa, contents aspirated ; no return (from a photograph in the col- lection of Dr. Lincoln, Wa- basha, Minn.). INJURIES AND DISEASES OF JOINTS. I 1 1 the fact that rotation of the arm is free from pain when the Hmb is in the position of moderate abduction, but excessively painful when by forced adduction or abduction the sac is made tense. In the case of the bursa under the psoas we have freedom from pain when the thigh is rotated in the position of flexion, but intense pain when this move- ment is carried out with the limb in extension. Suppuration is recognized by the occurrence of a chill or a marked rise in temperature with increased severity of all the symptoms. Chronic bursitis is a sequel of the acute form or may result from tuberculosis or syphilis. Trcatinejit. — In the acute form rest, cold applications, and pressure may be tried. If these measures do not give relief, the sac should be aspirated and firm pressure maintained by means of a bandage. When suppuration takes place the cavity should be laid open, irrigated with corrosive sublimate i : 2000, drained, and dressed antiseptically. CHAPTER V. INJURIES AND DISEASES OF JOINTS. I. INJURIES OF JOINTS. In examining any joint we must keep before our minds the follow- ing structures, any or all of which may be implicated when an articula- tion is injured or diseased : viz. the bones, articular cartilages, synovial membrane, ligaments, and muscles. The common injuries of joints are contusions, sprains, wounds, and dislocations. Contusions. — Direct violence, such as blows, kicks, or falls upon a joint, is important, from the fact that more or less hemorrhage may take place into the articular cavity, causing distention and affording a good culture-soil for septic germs should they chance to gain an entrance. When the bruise is not severe and no hemorrhage results, rest and the application of warm fomentations will soon restore normal conditions. Sprains are more serious. A forcible twist of a joint, as when a person " turns his ankle," is liable to cause more or less laceration of the tissues. The ligaments may be stretched or torn across, and may detach a thin scale from the bone, the synovial membrane may be rent, the muscles may be lacerated or overstretched, and their tendons thrown out of their grooves. In severe sprains the bones themselves are wrenched asunder, but slip back into place. Between a sprain of this kind and a dislocation the only difference is that in the one case the bones return to their normal position, while in the other they remain dislocated. It is a common saying that a bad sprain is worse than a fracture, and to a certain extent this is true. If much laceration of tissues occur and the most careful treatment be not employed, permanent weakness of the joint may result. The symptoms of sprain are — 112 SL'KGICAL n/AGiXOSIS AND TREATMENT. (i) Severe pain following a forcible twist or wrench of a joint. Sprains occur, as a rule, when the muscles are, so to speak, taken off their guard, and the same is true of dislocations. If the muscles were prepared for the strain and thrown into strong resisting contraction, it is doubtful whether sprains or dislocations would ever occur. The pain is of a severe and sickening character. The patient becomes deathly pale, nauseated, and perhaps falls fainting to the ground. As the more intense pain passes off a feeling of numbness succeeds, with a dull aching due to pressure on the nerves. Movement of the limb causes unbearable pain. There can usually be felt one or more spots which are intensely tender to pressure. These correspond to the lacerated ligaments. (2) Swelling sets in almost immediately, particularly if there be rupture of vessels in or about the joint. When the swelling is due to inflammatory exudation, it is longer delayed, and may not be observed until the end of twenty-four or forty-eight hours. (3) Discoloration of the skin follows the injury, varying in hue from a greenish-yellow to black, and if there be much extravasation of blood, the tissues about the joint may be filled with it.

Fracture of the lower end of the fibula is often difficult to dis- tinguish from a severe sprain of the ankle. The diagnosis can be settled by finding the characteristic deformity of this fracture and a particularly tender spot over the fibula by digital pressure. Spurious talipes valgus (flat-foot) need not cause any difficulty, as in this case there is a history of a gradual and prolonged debility, and not a sudden wrench as in sprain. Treatment. — In mild cases cold applied immediately after the injury will tend to prevent swelling and effusion into the joint by constricting the blood-vessels. If seen several hours after the accident, hot fomen- tations generally afford most relief Perfect rest in the elevated position is of the greatest importance, and will relieve pain better than liniments or lotions. Of all appliances, a flannel or an elastic bandage applied over a thin sheeting of absorbent cotton gives the greatest support and relief to the joint. In the case of the ankle care should be taken to fill in the hollows around the malleoli with cotton before applying the INJURIES AND DISEASES OF JOINTS. I 1 3 bandage. When there is much laceration of Hgaments the joint should not be used until perfect repair shall have taken place, otherwise there is a risk of permanent weakness. In cases of ordinary seventy it is sufficient for the patient to lay up for a few days, and then, with the joint firmly bandaged, he can move about on crutches in the case of a sprained ankle or knee, or with the arm in a sling when the wrist or elbow is the injured joint. Massage is of great value in protracted cases, or even in the early stages when the acute inflammation has subsided. It can be employed as follows : Raise the limb and relax the muscles. Begin with very hght movements, commencing above the joint, where there is still no swelling, and working downward to the articulation. The direction of the movements must always be toward the trunk, using the thumbs, the pulp of the fingers, or the palm of the hand according to the part of the limb that is being manipulated. The tender spots are the last to be touched. Swelling by this means gradually subsides, and as the circulation improves absorption rapidly takes place. Attention is next paid to the parts where extravasation is greatest, and by the thumbs or fingers these spaces are rubbed, moving in small circles upon the skin, and gradually increasing the pressure as the structures can tolerate the operation. Passive motion of the joint can be combined with these movements, for even in the case of ruptured ligaments a considerable degree of motion can be effected without throwing the ligaments into a state of tension. Wounds of Joints. — Wounds of joints must always be looked upon as serious injuries. They are common among artisans, such as ship-carpenters, who work with edged tools.' As gunshot injuries they are common, and they also occur as complications of dislocations and fractures. Even in non-penetrating wounds of joints the injury is a serious one, for if the wound be allowed to suppurate the cavity of the joint may be opened into and become the seat of serious mischief. Large wounds, laying open to view the articulating surfaces of the joint, are self-evident and easily diagnosed. In perforating wounds, however, it is not always easy to prove that the joint has been cut into. The most important sign is the escape of the synovial fluid more or less mixed with blood. It can be readily recognized by its viscidity when a drop of it is examined between the thumb and finger. If the amount of this fluid is large, it may be regarded as pathognomonic of a wound of a joint. It may happen that a small bursa is opened into which does not communicate with the articulation, but in this case the amount of fluid is small, and it ceases to come away after the first gush, while in the case of the true synovia it can be made to ooze out on flexion and extension of the joint. When no synovial fluid escapes, the rapid filling of the joint with blood would be strong evidence of a penetrating wound. Treatmoit. — Provided the wound is made by an aseptic instrument and no infection is allowed to gain access to the joint, these wounds are free from danger. An incision in the synovial membrane or in any other of the joint-structures, if kept thoroughly aseptic, will heal as readily as in any other tissues. The danger lies in the ease With which septic germs gain an entrance, and in the difficulty of keeping the 8 114 SURGICAL DIAGNOSIS AND TREATMENT. wound tliorouy;hl\' drained. Asepsis here is evcrythin<^ in treat- ment. Before touching the wound itself the skin for a considerable dis- tance around should be thoroughly washed with soap and water, and afterward with cither alcohol or turpentine, and lastly with corrosive- sublimate solution. The limb should be wrapped with sterilized towels. After cleansing the wound from all clots and impurities, the finger, scrupulously clean, assisted, if need be, by a probe, should explore the wound. It is often necessary to enlarge the wound in order that pieces of clothing carried in by the bullet or penetrating object and all particles of bone can be effectually removed. After thoroughly irri- gating the joint with sterilized water a drainage-tube is inserted, pass- ing through the joint from side to side if necessary. A full antiseptic dressing and immobilization of the limb on a splint complete the ope- ration. Should the joint become septic, the wound and every sinus about it must be opened up, washed out, and drained, and the process repeated as often as necessary. In gunshot wounds, which form a very dangerous class of these cases, the bones are often so destroyed as to require the removal of a considerable part of their articular ends. It is better to make an atypical resection rather than the typical operation, in order to leave the joint as little impaired as possible. Such cases are apt to result in bony ankylosis. Treves strongly advocates constant irrigation of the joint night and day to avoid the retention within the cavity of septic and decomposing materials, and excellent results have been obtained in very unpromising cases. When thorough drainage can be maintained there is little likelihood of great tension in the joint. Should this occur, the fluid must be got rid of by free openings and extra drainage-tubes. When there is danger of ankylosis resulting the limb should be kept in the position w'hich will be most useful to the patient in the event of a stiff joint. Dislocations. — When one of the bones entering into the forma- tion of a joint is permanently displaced from its normal relations with the other bones, it is said to be dislocated. In sprains a temporary displacement may take place, the bones immediately returning to their normal relations. Dislocations are classified as traumatic when the result of violence ; patlwlogical when the bones have become displaced owing to destruc- tive changes in the joint, as, for instance, in disease of the hip or knee ; congenital when occurring in titcro and as a result of non-development ; complete when the articular surfaces are entirely separated or only touch each other at their edges ; incomplete, or subluxations or partial, when the surfaces are not completely separated. For every ten cases of fractures you meet with, you may expect one of dislocation. Dis- locations occur at any time of life, but the most common period is between twenty and thirty years of age. The causes of dislocation are predisposing and immediate. Some people are naturally loose-jointed ; their ligaments are lax ; the area of contact between the articular surfaces is small ; and, altogether, the joints have not the normal power of resistance. A joint distended with fluid is thereby predisposed to dislocation. The immediate causes INJURIES AND DISEASES OF JOINTS. II5 may be summed up in a few words — external violence and muscular action. In examining a patient for dislocation, always strip the suspected joint of all clothing, and also its fellow on the opposite side of the body, which will serve for purposes of comparison. Four features must be kept in mind, and, as a rule, these four will settle the ques- tion. They are — Loss of symmetry ; want of normal mobility ; change in direction of the axis of the dislocated bone ; constant pain, relieved only by reduction. In certain forms of dislocation the end of the displaced bone can be felt in its abnormal position. A systematic manner of making the examination would be the following : {a) History. — Falls are common causes of the accident. A fall upon the shoulder is likely to dislocate the upper end of the humerus or fracture the clavicle. A fall upon the outstretched hand will dislocate the elbow of a child, but fracture the humerus of an adult. (/;) Inspectio7t. — A glance may decide the change in outline and show an unmistakable displacement of the bones. The eye may be assisted by measurements, as in dislocation of the hip, where shorten- ing or lengthening of the limb affords important evidence. The head of the humerus in the axilla may press upon the veins and cause edema of the arm. (r) Palpation. — The finger can be placed over the bony prominences and their position determined, as in the case of the condyles of the humerus and the olecranon at the elbow. Motion, both active and passive, must be tested. Voluntary movements are always restricted, and may be entirely lost. Passive motion cannot, as a rule, be tested until the patient has been placed under an anesthetic. When super- ficial palpation affords no satisfactory evidence deep pressure will frequently do so. Should these methods fail to satisfy the surgeon, he can gain much additional evidence by placing the patient under an anesthetic. Motion, which was before restricted on account of pain, can now be freely tested, and any want of normal mobility accurately determined. Great care must be taken to exclude fractures in the neighborhood of the joint, severe sprains, and separation of the epiphyses. Crepitus is pathognomonic of fracture, but in some cases it is wanting. It may be present in dislocations, owing to the fact that a dislocation and frac- ture may exist together. A dull rubbing sound, due to the movement of a dislocated bone on tendons or fascia, must not be mistaken for crepitus. In obscure cases, and especially when dislocation and fracture are combined, the .i'-rays may settle the diagnosis in a most satisfactory manner (see chapter on " The Rontgen Rays in Diagnosis "). When we consider the structure of a joint, it is not difficult to understand what takes place when dislocation occurs. One or more of the ligaments must be torn : rarely does stretching alone occur. The pain of dislocation is produced by two factors — viz. the violence to the ligaments and the pressure of the head of the bone in its new position. The capsule of the joint also suffers, and it is quite common to have this membrane torn. In joints of the ball-and-socket variety Il6 SURGICAL DIAGNOSIS AND TREATMENT. the bone is pushed through a rent in the capsule, and in some cases affords no little trouble to get it back through the opening which it has made. The muscles also suffer, for they not infrequently are over- stretched, lacerated, or torn from their attachments, perhaps bringing away a scale of bone with them. The bones thcmscKcs do not always escape. At the shoulder-joint the dislocated head of the humerus often breaks off a piece of the rim of the glenoid cavity ; the head of the femur may detach a part of the lip of the acetabulum ; the coronoid process of the ulna may be carried away in backward dislocation of the elbow. Complications may give no end of trouble. Fracture and disloca- tion combined are found at the shoulder, the elbow, the hip, aiid in fact may occur at any joint. The displaced bone may compress arteries, veins, nerves, and neighboring organs ; the bruising and tearing of soft parts may add to the seriousness of the injury, and the bone may be driv'en through the skin, thus forming a compound dislocation. In view of these conditions it is most important that a dislocation be reduced at the earliest possible moment. Pain, which continues as long as the part remains overstretched, will cease almost as soon as the bone is replaced ; the displacement, when once rectified, has no tendency to return ; the rent in the capsule speedily heals and the nor- mal condition of things is restored. The only conditions which war- rant delay in reducing a dislocation are great swelling and inflammation in and about the joint, also profound shock from associated injuries. While I mention the existence of swelling and inflammation as a reason for delay, I would also urge that when it is possible reduction is the very best means of getting rid of these conditions. Shock is important as prohibiting the use of anesthetics or painful manipulation. Trcatmoit. — Two difficulties confront us in reducing a dislocation : The bone may not readily come back through the rent which it has made in the capsule or it may become locked against another bone or be caught in a ligament, tendon, or dense fascia. The other obstacle is the contraction of the muscles which pass over the joint. Immedi- ately after a dislocation the muscles become relaxed, but after a time they regain their contractility and become rigidly contracted. This action tends to push the ends of the bones farther and farther past each other, and greatly increases the difficulty of bringing them back to position. To overcome this, steady traction must be made upon the muscles until by sheer fatigue they become relaxed. Under an anes- thetic relaxation is immediate and complete. Two methods of reduction are in vogue : I. Extension and Counter-extension. — By this method steady traction is made until the muscles relax or perhaps iDCCome torn, and the bone by sheer force is freed from its unnatural position, when with a snap the muscles draw it into its proper place. A good example of this method is seen in the case of the shoulder-joint, where, by placing the heel in the axilla to steady the trunk, traction is made upon the arm. and the bone slips back with a dull sound into the glenoid cavity. The older surgeons were in the habit of reducing luxations of the hip by means of pulleys and cords, which, adding immensely to the power, caused something to give way. We seldom see mechanical appliances of this INJURIES AND DISEASES OF JOINTS. 11/ description now, for in the second method we have something more rational and scientific, and at the same time generally applicable. 2. Manipulation. — This is adapted to the ball-and-socket joints, the articulations which are most complicated and likely to give most trouble. The procedure aims to relax the muscles, and then by suitable movements to free the head of the bone from its entanglements, bring it back through the rent in the capsule, and finally into its normal position. These manipulations will be described under Special Dis- locations. The after-treatment of dislocations is the same as that of sprains. Little is needed in the way of retentive apparatus, for there is but slight tendency to recurrence. At the same time, the joint should be kept at rest to allow the torn structures to heal and to regain their normal firmness and strength. Inflammation is seldom a source of trouble, but should it take place cold applications or evaporating lotions are generally all that are demanded. Care must be taken not to keep the joint too long at rest, for adhesions may result which will impair its movements. Passive motion, cautiously carried out, may be begun by the end of the first week, and massage, as in the case of sprains, will be found a valuable adjunct. Old dislocations are difficult to deal with. Changes in the structures take place which, after a time, render reduction a physical impossibility. The muscles become fibrous, and are liable to rupture before they can be stretched to their former length. The head of the bone in its new position becomes surrounded with fibrous tissue, forming a new socket. Over the normal socket, as at the acetabulum or glenoid fossa, the capsule is stretched and may become firmly attached, so that the bone cannot be brought back to position. Still, it sometimes happens that good results are attained even after long periods of luxation. In a boy ten years of age the writer reduced a dislocation of the femur into the obturator foramen after an interval of fifty-six days, in another after twelve weeks, both by manipulation ; and in a dislocation of the lower jaw after a period of six months. In the treatment of old luxations the same methods as are suitable for recent dislocations may be tried. Much greater force will, however, be necessary to break up the adhesions that have formed and to stretch the muscles to their former length. It is difficult to judge of the amount of force that it is safe to employ in cases of this kind. A moderate amount of traction will be of no avail, and too much may lead to serious consequences. The neck of the humerus or of the femur may be broken, vessels may be torn across, and even when every obstacle has given way and the bone is brought to its original position, the last state may be worse than the first. As a guide in the management of such cases the following directions may be useful : Always put the patient under an anesthetic. Break up the adhesions by manipulation and rotation, and avoid any leverage which is apt to fracture the bone. Wrap the limb in a wet towel to prevent injury to the skin. If manip- ulation fail, try the pulleys. Traction must be slow and steady, and sudden jerks avoided. While this is being done the surgeon, by direct manipulation, follows the head of the bone, and as soon as it is brought down endeavors to force it into its socket. Compound dislocations must be treated on much the same prin- ii8 SURGICAL DIAGNOSIS AND TKEATMENr. ciples as compound fractures. We have here the serious comphcation of a wound into the joint, and the dani^er of infection by septic germs, and consequently suppurative arthritis. It will often be a nice point to decide whether the proper course is to amputate or to attempt to save the limb. The amount of laceration and destruction of tissue, the interference with vascular supply, and the probability of securing a useful limb will have to enter into the calculation. At the knee the displaced bone may press upon the popliteal vessels so as to rupture their inner coats, while the outer are left intact. While the absence of hemorrhage would lead us to suppose that the vessels were uninjured, their giving way at a later period will lead to the most serious results. When the conditions seem favorable for saving the joint the greatest care must be taken in the dressing of the wound. Fragments of bone must be removed, the joint freed from all contamination, such as dirt or clothing, and thoroughly irrigated. Reduction is generally easy. The wound should be dressed in the usual manner and the limb im- mobilized by a splint. Thorough drainage is of the utmost conse- quence. When operative interference is demanded the choice will rest between excision of the joint and amputation of the limb. Diagnosis of 5pecial Dislocations. The I/Ower Jaw (Fig. 46). — There is only one direction in which the lower jaw can be dislocated, and that is forward. One side may be displaced (unilateral dislocation), or both sides (bilateral). The injury is easily recognized. The causes are muscular action and indirect violence. The acci- dent always happens when the mouth is open. The patient presents a peculiar appearance when the dislocation is bi- lateral. The mouth is widely open and speech is difficult. The labials he cannot pronounce at all. He holds his hand against the jaw to prevent further dis- placement, and saliva dribbles from his mouth. Place your fingers at the angle of the jaw, and you will find in front of the ear a depression instead of the natural prominence caused by the condyle. In front of this there is a prominence due to the new position of the bone and to the contraction of some of the fibers of the masseter muscle. The jaw can be moved downward to a slight degree, but this is all. Pain is severe, owing to stretching of the parts, except it be a case in which the jaw has been repeatedly dislocated. When only one side of the jaw is the seat of luxation, the symptoms, although not so marked, are equally charac- teristic. The lower jaw appears to be pushed toward the opposite side, and therefore its teeth do not fit normally against those of the upper. The face is not much distorted, and pain is only felt at one side. Fig. 46. — Dislocation of lower jaw. INJURIES AXD DISEASES OF JOINTS. II9 In young persons a partial dislocation is sometimes met with in which the condyle is displaced slightly forward when the mouth is widely opened as in yawning. The patient learns to rectify the position by pressing the chin upward. Errors in Diagnosis. — i. Congenital dislocation of the jaw has been mistaken for traumatic unilateral dislocation. In the congenital form the movements are but slightly impaired or are even normal, which is never the case in the traumatic variety. The upper teeth project beyond the under teeth. There is absence of salivation, and one side of the face is longer than the other. 2. Chronic rheumatoid arthritis is another disease which may be mistaken for dislocation. The history shows that the condition has come on slowly. It is a disease of old age, there is no salivation, and the same condition exists in other joints. Treatment. — The patient, seated in a chair, has his head supported by an assistant. Protect your thumbs by folds of a clean handkerchief, and, placing one over the molar teeth on each side, press steadily down- ward, while the fingers at the same time tilt the chin upward. The thumbs should be placed as far back as possible. When great difficulty is experienced, as in old dislocations, one side can be reduced first, and the other afterward, care being taken lest the first be again displaced while the second is being reduced. In very obstinate cases, although these are uncommon, great force has to be employed. A wedge of cork or wood may be placed between the molar teeth and the chin drawn upward with strong force ; or a tourniquet may be placed over the head and under the chin, and screwed slowly and steadily up until the jaw is brought into place. A powerful pair of forceps may be introduced between the last molar teeth and their blades separated forcibly. In some cases, direct pressure, made backward upon the coronoid process, will prove successful. It rarely happens that this process becomes entangled in the fibers of the temporal muscle. When this occurs depress the chin before attempting to elevate it. lExamination of Injuries about the Clavicle and Shoulder. — The most convenient position for the examination of injuries about the shoulder is- to have the patient seated upon a stool or chair with his back toward you. Place your fore fingers in the suprasternal notch and pass them outward. You can in this way easily decide whether the ends of the clavicle are in position. The clavicles are subcutaneous, and by passing the fingers along their upper borders any irregularity in their shape will decide the existence of fracture. From the outer end of the clavicle the finger can be run along each acromion process and spine of the scapula to the posterior border of this bone. Note any tender spot or any irregularity in the bone. Next take the shoulder, and, placing the hands flat, with a thumb upon each acromion process, note whether the head of the humerus can be plainly felt beneath the hand. Press upon the deltoid muscle and feel for the glenoid fossa of the scapula. If the glenoid fossa can be felt, it is proof of dislocation of the humerus, and then the head of the bone must be sought for. It will be found in one of three locations — under the glenoid fossa, under the clavicle, or under the spine of the scapula. When you have found the head of the humerus rotate the bone 120 SL'KG/C.IL DLl GNOSIS AND TREATMENT. gcntl}' by grasping the elbow, and notice whether or not the head moves with the rest of the bone. If there be fracture, crepitus can be felt. Next examine the coracoid process. There is a groov^e between the pectoralis major and deltoid which allows you to feel it without much difhcult}-. Into this groove press the points of your fingers and find the process. Observe whether it is movable or whether pressure upon it causes pain or crepitus. From this point the fingers can be passed around the shoulders to note any difference in contour on the two sides. To examine the axilla raise the arm gently from the side, and with the fingers in the axilla feel for the head of the humerus and note any undue prominence, always comparing the uninjured with the injured side. To examine the scapula, place the forearm of the patient behind his back, which throws the lower angle of the scapula out from the chest- wall. The margins of the bone can be followed with the fingers, the inferior angle grasped, and crepitus or mobility noted. Up to this point your examination has been made with the patient's back toward you ; now stand in front of him. Have him hold both arms alike, and note any difference in their outlines. Look for any angularity in the arm or forearm which would indicate fracture, or for undue projection of the point of the elbow which would be evidence of dislocation. We continue the examination by following the shaft of the humerus. Place a thumb on the inner side of the surgical neck of each bone, and with the fingers grasp the outer side ; in this way the hand can be run down along the bone to the elbow in search of any projecting frag- ments or other deformity. Should any such be found, grasp the arm above the suspected spot with one hand and with the other rotate the elbow for crepitus. To Bxamine the Blbow. — Still standing in front of the patient, take his elbows into the palms of your hands, with your fore finger resting on the tip of the olecranon, the thumb on the outer epicondyle, and the middle finger on the inner epicondyle of the humerus. In the normal condition of the joint these three bony points are in line. Any deviation from this should be noted. Look for a gap in the olecranon which would indicate fracture, or for the sigmoid notch of the ulna which would point to dislocation. Now move the joint and observe whether its action is free and painless. Place the thumb of your left hand just below the outer condyle, and with the right rotate the patient's wrist ; the head of the radius will be felt rolling beneath the thumb. Should this mov^ement be painful, you may suspect fracture ; the existence of crepitus will leave no doubt. Grasp each epicondyle in its turn, and attempt to move it upon the rest of the bone, and note the power of the patient to pronate and supinate the forearm. The olecranon is subcutaneous, and the fingers can be run along it in search of fracture. Usually a large gap into which the end of one or more fingers can be placed will be found when this process is fractured. To complete the search follow the tendon of the triceps down to its insertion into the ulna. Dislocation of the Clavicle. — The dislocations of the clavicle are seven in number — three at the sternal end, three at the acromial INJURIES AND DISEASES OF JOINTS. 121 end, and one of both ends simultaneously. At the sternal end the accident is rare, owing to the great mobility of the shoulder, which prevents any severe strain upon the sterno-clavicular joint, except when the force is acting upon the clavicle directly. We have here an illustration of the rule that when it comes to a test between ligaments and bone the bone has to yield. A force acting upon the clavicle will almost surely break the bone before it can be torn from its attachments to the sternum. When dislocation takes place it is in one of three directions — \\z. forward, backward, or upward. Forward dislocation is the most common. The bone can be readily felt as a prominence in front of the sternum, while an exam- ination of the suprasternal notch will show its absence from the normal position. The portion of the sterno-mastoid muscle which is attached to the clavicle is put upon the stretch, and throws the patient's head downward and forward ; movement of the shoulders forward is attended with severe pain. Backward dislocation is also easily recognized by a depression at the normal position of the end of the bone. Very disagreeable symptoms are produced if the bone is sufficiently displaced to cause pressure upon the esophagus or trachea, in the one case causing dysphagia, in the other dyspnea. Upward dislocation is the rarest of the three forms, and is really a variety of the backward dislocation, for the bone is always displaced backward as well as upward. The bone fills up the suprasternal notch and lies between the sternal portion of the sterno-mastoid and the sterno-hyoid muscles. The most important of these three is the backward dislocation, for very prompt action may be required to save the patient's life when the trachea is pressed upon by the displaced bone. Treatment. — One method of reduction serves for all of these forms of dislocation. Seat the patient upon a low stool with his back toward you. Place his elbows close to the sides and a little in front of the median lateral line. Then with your knee against his spine and between his scapulae grasp the shoulders and bring them backw^ard. If the bone does not slip into position at once, direct manipulation can be employed to aid in the reduction. When these measures fail, place a large pad in the axilla, and, using the arm as a lever, press the elbow in toward the side. Reduction, however, is the smallest part of the treatment ; the dif- ficulty is to keep the bone in position after it has been replaced. This can be readily understood when we recollect that the articular surfaces are flat and smooth, the ligaments are usually ruptured, while even the unavoidable movements of respiration are sufficient to disturb the joint. In forivard dislocation a double figure-of-8 bandage is probably the best appliance. A firm pad or a well-padded splint is placed between the shoulders and the bandage passed over each alternately to bring the shoulders back as far as possible. Velpeau's method is the best for dislocation backward or backward and 7ip%vard. It consists in placing a pad in the axilla and in drawing the elbow forward and upward across the chest, so that the hand of the affected side can be placed upon the opposite shoulder. The elbow, forearm, and hand are 122 SURGICAL DIAGNOSIS AND TREATMENT. then flexed firmly in position by strips of adhesive plaster. In all cases it is necessary to place over the end of the bone a pad covered with adhesive plaster to keep it from slipping, and hold it in position by a roller bandage. It is absolutely necessary to keep the arm rigidly immobilized for at least three weeks, after which the bandage may be to a certain extent relaxed, but no movement should be allowed for three or four weeks longer. Dislocation of the Acromial End (Fig. 47). — The cause is usually a fall or a blow upon the shoulder. The direction is commonly upward or upward and outward, so that the end of the clavicle is carried over the end of the acromion process. Reduction is very easily effected by pressing the arm upward and backward, when the end of the clavicle can be replaced by direct manipulation. Should crepitus be felt during this movement, it may be set down as due to a fracture of the edge of the articulation. Should there be any doubt about the outer end of the clavicle itself being broken, measure- ment of the bone and comparison with its fellow of the sound side will settle the question. It is exceedingly difficult to keep the bone in position after re- duction. The best method is probably that recommended by Stimson. Take a piece of strong adhesive plaster three inches wide, and, applying the middle of it to the point of the elbow flexed to a right angle, bring the ends up over the end of the clavicle before and behind the arm, and allow one to overlap the other on the shoulder. The forearm is carried in a sling, and the arm bound to the side by a broad bandage passing round the body. Dislocation of the Sternum. — It is difficult to distinguish this injury from fracture. It is generally associated with fracture or dis- location of the ribs or the costal cartilages. When uncomplicated dislocation takes place, it is either the manubrium dislocated from the body or the ensiform cartilage from the body. Diagnosis is not usually difficult. The bone being subcutaneous, a change in its outline can be felt. The junction of the manubrium with the body corresponds with the end of the second costal cartilage. This relation will be found to have been disturbed in dislocation. Reduction is effected by requiring the patient to draw a deep breath while the fragments are directly pressed into position. Should this fail, forcible flexion of the trunk backward will prove a valuable aid. Many cases have remained unreduced and little or no incon- venience resulted. The cnsifonn cartilage may be dislocated, so that its point is directed forward or backward. It causes no great inconvenience as a rule, Fig. 47. — Upward dislocation of acromial end of right clavicle (Keen and White). INJURIES AND DISEASES OF JOINTS. 123 although vomiting has been attributed to a backward displacement. When the symptoms are severe enough to warrant interference, reduc- tion can be effected by drawing the cartilage forward by the fingers or by a sharp hook inserted through the skin. Dislocation at the Shoulder. — In a joint so freely movable and so exposed to violence it is not surprising that dislocations at the shoulder occur as frequently as all other dislocations combined. The glenoid cavity is shallow, and the head of the humerus finds no such deep socket to rest in as the head of the femur finds in the acetabulum. The capsule is weak, loose, and easily torn. The joint is dependent upon muscles and tendons for its support, while the great length of the humerus affords a powerful leverage which can force the joint asunder without difficulty. The aspect of the glenoid fossa is forward and out- ward. The head of the humerus can be displaced from it in three directions — viz. forward, backward, and downward, very rarely upward. Forward Dislocations. — Two varieties of this form are recognized : Fig. 48. — Kocher's method of reducing dislocation of shoulder : first movement, abduction and external rotation. 1. Subcoracoid, when the bone has little more than slipped off the glenoid fossa and lies under the coracoid process. 2. Subclavicular, when the head of the humerus has travelled farther forward and lies beneath the clavicle. Some authors give a third variety, when the head of the bone lies a little farther inward than the coracoid, and call it intracoracoid. Of the three varieties the subcoracoid is the most common. The bone lies about a finger's breadth below the coracoid process. The inner and lower portion of the capsule is torn along the edge of the glenoid fossa. Some of the muscles about the joint may be torn, such as the subscapularis, the supraspinatus, the infraspinatus, and the teres minor. Injury to the bones themselves is not uncommon. The greater tuberosity may be torn off, or the head of the humerus may be bruised by forcible contact with the edge of the glenoid fossa. 124 SURGICAL DIAGNOSIS AND TREATMENT. Syiiiptoins. — Following the method of examination already outlined, we observe — 1. C/ia)ii^f of Con four- -The deltoid is flattened, and the normal fulness of the shoulder on its anterior and outer aspect is lost. The injured elbow hangs at a little distance from the side. The axis of the humerus passes a little in front of the glenoid fossa. The anterior fold of the axilla is lowered. 2. Abnormal Position of Bony Prominences. — Instead of the normal bony resistance below the front and outside of the acromion, a depres- sion is felt, while a well-marked prominence is felt farther forward and below the coracoid process. Press upon this prominence with your fingers and you will find that it rotates with the arm. 3. Impaired Mobility. — Active movement is painful and perhaps impossible. Passive movement is greatly limited. The arm can be abducted, but cannot be so far adducted as to allow the hand to be Fig. 49. — Kocher's method : second movement, advancement of elbow forward, upward, and inward, still maintaining external rotation. placed upon the opposite shoulder or the elbow- against the front of the chest. When measurement is desired, both arms should be placed in exactly the same position and the tape stretched from the tip of the acromion process to the olecranon. When the dislocation is farther forward the symptoms are the same, except that the elbow is farther from the side, and the head of the humerus is felt in its new position — viz. intracoracoid, or subclavicular. Treatment. — i. Manipulation. — Kocher's method (Figs. 48, 49, 50) of manipulation is the best. Flex the elbow to a right angle and press it closely to the side. Make external rotation — i. e. turn the forearm as far as possible away from the chest, when the head of the humerus will roll outward in front of and below the acromion. Keep up the external rotation, carry the elbow well forward and upward, rotate the arm inward, and lower the elbow. This movement may be aided by an assistant's directly manipulating the head of the bone in the later INJURIES AND DISEASES OF JOINTS. 125 Steps, or by the use of a band in the axilla to draw the head of the humerus outward. 2. Extension and Countcr-cxtcnskvi. — An old method of reducing all forms of dislocation of the shoulder was to have the patient placed on a table, couch, or the floor, when the surgeon, removing his boot Fig. 50. — Kocher's method : rotation inward, the hand being carried toward the opposite shoulder. and sitting beside the thigh of the patient, placed his heel in the axilla, to make counter-extension, while, grasping the wrist of the affected limb, he steadily drew upon it until the bone slipped into position. While this method is applicable to all dislocations of the shoulder, it Fig. 51. — Reduction of dislocation of humerus. is not without its disadvantages. Rupture of the axillary vessels has more than once occurred. It should never be resorted to in the aged or in those whose arteries are diseased. When traction has to be employed it is better to make it in a direction at right angles to the 126 SURGICAL DIAGNOSIS AND TREATMENT. body. Place a folded sheet around the chest and have an assistant hold it firmly on the sound side. Then, grasping the injured limb by the forearm and elbow, draw directly outward, while the assistant makes counter-extension by the sheet (Fig. 51). Or, while the patient is l)'ing down, make traction on the arm until the muscles are over- come ; then, using the clenched fist of your disengaged hand as a fulcrum, bring the arm forcibly in toward the che.st. Backward Dislocation. — Two dislocations backward are recog- nized : 1. Subacromial, when the head of the humerus lies below the acromion and its anatomical neck rests against the edge of the glenoid fossa. ■ This is not very common. 2. Subspinous, when the bone goes a little farther, resting below the spine of the scapula. Symptoms. — The want of symmetry will be shown by a loss of fulness of the shoulder in front and an increase behind. The head of the bone is generally felt without difficulty, lying behind the glenoid fossa. The elbow lies close to the side and the arm is rotated inward. The coracoid and the anterior edge of the acromion stand out with unnatural prominence. Voluntary motion is lost ; passive motion is painful and restricted. Downward Dislocation. — This form is rare, but when it does occur the symptoms are very characteristic (Fig. 52). The accident occurs Fig. 52. — Subglenoid dislocation (Stimson). when the arm is abducted with sufficient force to tear the capsule, with rotation or direct force downward, so that the head of the humerus slips below the glenoid cavity. Sometimes the head of the bone is INJURIES AND DISEASES OE JOINTS. 12/ directly below the glenoid, but most commonly it is below and a little in front. The name subglenoid is given to both of these varieties. In rare cases the bone has slipped below the glenoid cavity with the arm placed upward and close to the side of the head. This variety has been called hixatio crccta. The syinptoins of subglenoid dislocation are very similar to those of the subcoracoid, only more pronounced. A striking feature is the marked angularity given to the shoulder by the prominence of the acromion. Treatment. — As the bone lies upon or close to the axillary vessels, great care must be taken lest these be injured. Complete relaxation of the muscles must be secured under chloroform. Traction can then be made in moderate abduction, while, at the same time, the bone can be helped back into position by direct manipulation. Upward dislocation is a curiosity. Several cases have been reported. One of these occurred during an epileptic convulsion. Another was produced by a blow upon the acromion while the arm was raised. A fall upon the elbow caused the third. The recognition of the head of the bone in its unnatural position is not difficult. Both active and passive motions are restricted. The elbow is directed back- ward to a slight degree and the arm lies close to the side. Errors in diagnosis are liable to occur by mistaking a dislocation for — 1. Fracture of the neck of the scapula; 2. Fracture of the surgical neck of the humerus ; 3. Separation of the greater tuberosity of the humerus ; 4. Fracture at the anatomical neck. In all of these the elbow can be made to touch the side, while in dislocation it cannot. Crepitus is also an unfailing guide in nearly all. Separation of the greater tuberosity will prove the most puzzling, and the point will be to decide between it and subspinous dislocation. In both cases a tumor will be felt upon the scapula. It is either the detached tuberosity or the head of the humerus. In the one case it rotates with the humerus (dislocation) ; in the other it is small and is not affected by rotation. Dislocations at the Klbow. — This joint, being made up of three bones with the two prominences of the ulna, is subject to a great variety of dislocations. To avoid unnecessary complications I shall classify them as follows : 1. Common Dislocations. — {a) Dislocation of the radius and ulna together backward and diagonally backward and outward ; {b) Dis- location of the radius separately. 2. Rare Dislocations. — [a) Dislocation of both bones forward, out- ward, or inward; {b) Dislocation of the ulna alone; (c) Dislocation of both bones separately, the one being driven forward, the other back- ward. Dislocation of both Radius and Ulna. — Examination. — Place the patient upon a chair and stand in front of him. Grasp the two elbows in the palms of your hands, and place your thumbs on the external epicondyles, the middle fingers on the internal epicondyles, and the tips of the fore fingers on the tips of the olecranon processes. When the joint is extended these three points should form a line transversely to 128 SURGICAL DIAGNOSIS AND TREATMENT. the axis of the arm. When the elbow is bent the tip of the olecranon sinks below the epicondyles. Any disturbance of these relations will indicate that something is wrong with the joint — either dislocation or fracture. Backivard Dislocation of Both Bones (Fig. 53). — In this case the olecranon is carried far back, and the distance between it and the epi- condyles is increased. The head of the radius is felt at the back of the outer con- dyle. The greater sigmoid notch of the ulna can be felt at the back of the joint, and the tendon of the triceps stands out prominently. Passive flexion and extension are greatly restricted. There is usually considerable swelling and pain. Treatmeiit. — While an assistant holds the lower end of the humerus, and at the same time pushes it slightly backward, make traction upon the forearm in the extended position. This is generally suf- ficient to overcome the action of the mus- cles and to bring the coronoid process of the ulna in front of the humerus, where it belongs. A time - honored plan, often spoken of as Sir Astley Cooper's method, is to place your knee on the bend of the elbow, and, grasping the wrist, flex the joint strongly over the knee as a fulcrum. If any difficulty is experienced in either of these methods, the patient should be anes- thetized. After reduction the limb should be immobilized for about three weeks. During this time massage will be found useful, but passive motion is unnecessary, and may even prove harmful. Any stiffness of the joint which remains after removing the splints rapidly disappears under exercise of the limb. Compound dislocation at the elbow is a serious matter. When there is much injury to the end of one or more of the bones, the destroyed portions must be removed as an atypical resection ; other- wise reduction should be effected, thorough drainage established, and the principles carried out which are applicable to wounds of joints. Forxvard Dislocation of Both Bones. — This accident is always the result of great violence, and the injury is almost sure to be complicated with fracture of the olecranon. In this variety the olecranon lies in front of the humerus or may find its way into the coronoid fossa. The arm is bent to nearly a right angle, and the forearm is supinated. When the normal position of the olecranon is examined, there will be found a flat, broad surface caused by the lower end of the humerus. When the olecranon is broken off, it is retained on the posterior aspect of the joint, but drawn upward by the triceps. Fortunately, this dis- location is rare. Treatment. — The obstacle to reduction is the olecranon, which, if Fig. 53. — Dislocation of the elbow backward (Stimson). INJURIES AND DISEASES OF JOINTS. 129 not fractured, must be disengaged from the coronoid fossa and made to slip over the articular end of the humerus to its normal position. After thoroughly relaxing the muscles under an anesthetic, hold the forearm at a right angle, make extension from the wrist and counter- extension from the lower end of the humerus. When the olecranon is disengaged from the coronoid fossa make direct pressure downward upon the anterior aspect of the forearm, close to the elbow. Examine carefully, after reduction, to make sure that the head of the radius is in its proper position. Imvard Dislocation of Both Bones. — This is an incomplete dislo- cation. The olecranon will be found out of its normal position and toward the inner aspect of the joint. The external condyle will be more prominent, and the internal less prominent, than on the sound side. When there is not much swelling the head of the radius can be detected on the articular surface of the humerus about its, middle. Treatment. — ]\Iake extension and counter-extension in the flexed position (combined with direct pressure), gradually bringing the arm into the position of full extension. Ontzvard Dislocation of Both Bones. — The inner condyle of the humerus is naturally more prominent than the external, but in this accident the prominence is greatly exaggerated, while the external condyle can with difficulty be felt. The hand is pronated, and the elbow bent to an angle of about 120° (Fig. 54). Treatment. — Extension and counter-extension with direct lat- eral pressure.. The very rare deformity known as divergent dislocation, in which the ulna and radius are dislocated separately, needs no special men- tion. Dislocation of the Radius Alone. — This can take place in five directions — forward, back- ward, outward, inward, and down- ward. Foriuai'd dislocation is recog- nized by finding a tumor in front of the humerus which rotates with the elbow, while a depression is found in the normal position of the head of the radius at the ex- ternal condyle. Supination of the hand causes pain, while pronation is not impaired. The arm can be extended without difficulty, but common complication of this injury is fracture of the shaft of the ulna. Treatment. — In some cases reduction is difficult or even impossible, while in others it proves very simple. Extend the forearm, make 9 Fig. 54. — Outward (supra-epicondylar) dislo- cation of the elbow (Keen and White). flexed only to a right angle. A 130 SURGICAL DIAGNOSIS AND TREATMENT. steady adduction to disengage the head of the bone, and then by direct pressure force it into its proper position. Backzvard (dislocation of the radius is rare. The tumor in this case is felt behind the humerus, and moves with rotation of the radius. When the ulna is fractured the tendency is for the radius to be pushed upward, the forearm at the same time being abducted. Reduction is effected by direct pressure upon the head of the radius. Oittzcard dislocation is exceedingly rare, and is readily diagnosed by the position of the head of the bone at the outer side of the elbow. Inward dislocation cannot occur without displacement of the ulna as well. Dozvnu'ard dislocation, an accident of young, loose-jointed children, is caused by forcibly drawing upon the hand of a child of three years of age or less. After a jerk the child cries with pain and cannot use the arm. The limb hangs by the side with the forearm slightly pro- nated. On examination there is tenderness over the head of the radius, and the bone may be felt to be displaced downward. It is supposed to be below the orbicular ligament. Treatment. — Steadily supinate the arm, when a slight click will be felt and no more inconvenience will be experienced. Dislocation of the Ulna Alone. — This is a rare accident. It cannot be displaced forward without fracture of the olecranon. When dislocated backward the marked prominence of the olecranon behind and the trochlea in front leaves no room for doubt. Old, unreduced dislocations at the elbow are difficult to treat. If the patient is young and there has been disturbance of the periosteum at the time of the injury, new bone has probably been thrown out which forms an insuperable barrier to the movements of the joint. The displaced olecranon becomes firmly bound down by adhesions to the posterior surfaces of the humerus, and should the limb become fixed in an extended position, it is almost useless to the patient. Three courses are open to the surgeon : 1. Forcible flexion of the joint, with or without fracture of the olecranon. 2. Open arthrotomy, with division of all the tissues which prevent movement. 3. Resection of the joint. Dislocation at the Wrist -joint. — Examination of the Wrist and Hand. — The bones of the wrist and hand being subcutaneous, any irregularity due to displacement or fracture is readily detected by the eye or palpated by the fingers. Run your fingers over the dorsum of the carpal, metacarpal, and phalangeal bones and note any irregularity. Grasp the extremities of each bone, and ascertain whether there be movement or crepitus. Dislocation of the Lower End of the Ulna. — This can occur backward or forward. In either case the end of the ulna stands out prominently, can be recognized in its new position, and frequently over- laps the end of the radius. Direct pressure is sufficient to replace the bone. Dislocation of the carpus from the radius. This may take place in four directions — forward, backward, outward, and inward. INJURIES AND DISEASES OF JOINTS. I3I These deformities present no difificulties in their diagnosis. It must be borne in mind that dislocation at the wrist is very rare compared with two other injuries for which it is Hable to be mistaken. These are Colles's fracture and sprain. Careful attention to the symptoms of Colles's fracture — the silver-fork appearance, the position of the styloid process of the radius, and its relation to the ulna — will leave no room for doubt. In this fracture the styloid process is below the prominence on the back of the wrist, while in dislocation of the carpus forward the bones form a rounded prominence on the front of the wrist, behind which is a sharply-defined line representing the lower end of the radius. Of the carpal bones the semilunar is the one which is most fre- quently dislocated singly. The displacement is forward. Except when swelling is great the deformity is easily recognized. Treatjnent consists in replacing the bone by direct pressure. Dislocation at the Carpo-metacarpal Joints. — The most frequent and the most important of these is found at the base of the metacarpal bone of the thumb. The direction is backward, and the luxation is frequently incomplete. The head of the bone can be felt between the tendons of the extensor primi and secundi internodii pollicis. Reduc- tion is readily effected by extension, counter-extension, and direct pres- sure. Immobilization should be maintained for one or two weeks, as the displacement is liable to return. Metacarpo-phalangeal Dislocation. — This is most frequently seen in the thumb. Small and insignificant as this joint appears, the difficulty of reducing a dislocation here is often very great, owing to the inter- position of the anterior ligament with the sesamoid bones. The phalanx is generally displaced backward and overlaps the metacarpal bone. A very troublesome complication of this injury arises when the glenoid ligament is turned upward and lies between the phalanx and the metacarpal bone. This may occur during attempts at reduction. Treatment. — Make strong extension and press the thumb downward until the anterior edge of the base of the phalanx overlaps the lower end of the metacarpal bone. Then flex the thumb, and the bone slips into its place. Sometimes the glenoid ligament and the heads of the flexor brevis form a sort of button-hole through which the end of the phalanx must be manipulated. This can be done by direct pressure combined with rotation, first to one side and then to the other. Dislocations of the Phalanges. — These offer no difficulty in diag- nosis and seldom prove obstinate in reduction. To obtain a grasp upon them various devices have been resorted to, of which the best and readiest is the clove hitch. Dislocations at the Hip-joint. — Examination of the Hip. — The patient, divested of ordinary clothing, should be placed upon a table or firm mattress. In the case of females a thin night-dress or sheet cover- ing the body need not interfere with the examination and renders the ordeal less embarrassing. See that the body lies perfectly straight, and that a line from one anterior superior spine of the ilium to the other lies at right angles to a line from the ensiform cartilage to the sym- physis pubis. I. Inspection. — With the spine resting its whole length upon the 132 SURGICAL DIAGNOSIS AND TREATMENT. table observe whether one or both knees are flexed. The knee being pressed down upon the table, observe if the spine becomes lordosed (arched forward). If this occur, it is strong evidence of disease of the joint, of psoas abscess, of sacro-iliac disease when complicated with psoas abscess, or of inflamed bursa; beneath the psoas. Does the suspected limb lie parallel to its fellow ? The thighs are normally directed inward in women, slightly so in men. If the thigh is abducted, it is evidence of the early stage of coxitis or of .synovitis of the hip. Adduction of the thigh points to dislocation on the dorsum ilii and to the later stages of joint-disease. Observe whether the limb is rotated in or out. Eversion occurs in fracture of the neck of the femur or when the synovial cavity is dis- tended, as in synovitis, or when there is tension of the psoas and iliacus muscles as in abscess. Inversion is evidence of dislocation or of the later stages of morbus coxce. 2. Measurement. — The limb can be best measured from the anterior superior spine of the ilium to the external malleolus. Shortening indi- cates at least two of the forms of dislocation — on the dorsum ilii and into the sciatic notch. It is also a sign of fracture of the neck of the femur and of advanced hip-disease. Do not be misled by the apparent lengthening of a limb. This is due to a simple tilting of the pelvis. 3. Mobility of the Joint. — Grasp the knee with one hand, place the other upon the outer side of the pelvis, and put the joint through the several movements of flexion, extension, adduction, abduction, and rotation. Observe carefully whether the pelvis moves with the femur ; if so, whether this is due to bony ankylosis or to rigidity of muscles, and whether the movements are attended with pain. The patient's attention should be diverted, otherwise it will be difficult ta determine how much muscular rigidity is due to his fear of being hurt. When doubt on this point still remains, give an anesthetic, and if rigidity passes off you may know' it was due to muscular contrac- tion. 4. Exami7iation of the Bones. — Begin with the trochanter ; compare the two sides, and then, applying the palm of the hand, press inward firmly and gradually against the neck of the femur. Pain or tenderness under this test is evidence of inflammation of the neck or head of the femur. The head of the bone may be sought for on the dorsum ilii, the buttock, or near the pubis. Grasp the iliac crests and press them toward or apart from each other. Pain felt in these movements should direct attention to inflammation in the sacro-iliac joint. Dislocations at the hip can never be intelligently studied without first having mastered two small and apparently insignificant structures that enter into the formation of the joint. One of these is the Y-liga- ment, so called, and the other is the obturator internus muscle. Before Prof Henry J. Bigelow of Boston revolutionized the treatment of dislocation at the hip the great obstacle to reduction was supposed to be the resistance of the powerful muscles about the joint. Dr. Bigelow cut away all the other muscles, and still found that these two structures, the Y-ligament and the obturator internus muscle, were sufficient to produce all the varieties of luxation of this joint, and also- INJURIES AND DISEASES OF JOINTS. 133 to constitute the obstacles which prevent the return of the bone to the acetabulum. What is the Y-ligament ? It is a portion of the capsular ligament which is thick and strong, and remains untorn when the head of the bone makes a rent in any other part of the capsule. The capsular ligament is a sort of tube surrounding the joint. It arises from the circumference of the acetabulum and the parts surrounding, and is inserted near the junction of the neck of the femur with the trochanter. The human being walks erect, and naturally a severe jolt transmitted to the joint, as in jumping from a height, is likely to dislocate the bone upward. To prevent this the capsular ligament is much thicker and stronger on that side, and forms a powerful band which helps to keep the joint in position. This part of the capsule, which goes under the various names of the " Y-ligament," the " ilio-femoral ligament," and " Bertin's ligament," arises from the anterior inferior spinous process of the ilium, and from the bone below as far Fig. 55. — The Y-ligament. Fig. 56. — The obturator internus muscle as the border of the acetabulum. This dense band, sometimes a quarter of an inch in thickness, passes down toward the great trochanter, where it divides into two "branches, thus forming an inverted letter Y. One of these branches is inserted into the anterior and superior part of the great trochanter. The other goes farther down, and is inserted into the femur close to the lesser trochanter (Fig. 55). Bear in mind, that in all dislocations at the hip this ligament remains untorn, while every other structure may be lacerated. By its tension is determined the different positions which characterize the deformity, such as flexion, inversion, eversion, adduction, or abduction of the limb. TJic obturator intcrmis muscle, the other structure which plays an im- portant part in some dislocations, arises inside the pelvis from the inner surface of the obturator membrane and from the bony edge of the 134 SURGICAL DIAGNOSIS AND TREATMENT. foramen. Its fibers converge into a tendon which passes toward the lesser sciatic notch, where it winds around a trochlear surface, and is inserted into the upper border of the great trochanter in front of the pyriforniis (Fig. 56). Dislocations at the hip-joint are four in number — two back- ward and two forward. If a dislocation is backward, it is either on the dorsum ilii or into the sciatic notch ; if forward, it is either on the obturator foramen or on the pubis. Dislocation upon the Dorsum Ihi. — Supposing a person to fall from a height, his abducted knee first striking the ground and with the body bent forward, the force will come upon the posterior wall of the capsular ligament and the ligamentum teres, both of which will yield readily. The limb, being abducted, loses the support of the great mus- cles, and the head of the femur slips out of its socket backward. It must land in one of two places, the sciatic notch or the dorsum ilii. The same accident is liable to occur when a person is bending forward and a heavy body falls upon his back or hips. While the bone is slip- ping backward the Y-ligament becomes tense, and would prevent the displacement but for one thing. The femur rotates inward, so that, w hile the Y-ligament holds the trochanter firmly enough, the head of the bone slips outward. This accounts for one of the characteristic signs — viz. inver- sion of the foot. The head of the femur being thrown backward and the Y-ligament still on the stretch, the knee is of necessity thrown forward ; both of these deformities continue until the luxation is reduced. The capsule is torn at its posterior part, and also some of the muscles about the joint, such as the quadratus femoris, the obturator in- ternus and externus, and the pyriformis. Symptoms. — The limb is shortened from one to two inches. The knee is directed to the sound limb, and the toes lie upon the instep of the opposite foot. The head of the bone can, in some cases, be felt in its new position on the dorsum ilii (Fig. 57). Dislocation into the Sciatic Notch. — This is also a backward dislocation, and presents the same symptoms as the iliac variety, only to a less marked degree. The shortening is not more than three- quarters of an inch to an inch. Inversion of the toes and adduction of the thigh are also present, but less marked than in the former case. The toes of the injured side rest upon the ball of the great toe of the opposite foot. There is little difficulty in diagnosing these two dislocations from one another, nor would a failure to do so result in any serious consequences, as the treatment is the same. The Fig. 57. — Dislocation on dorsum ilii. INJURIES AND DISEASES OF JOINTS. 135 mistake most likely to be made is to fail to distinguish between sciatic dislocation and fracture of the neck of the femur with inversion of the foot. In most cases of fracture there is eversion of the foot, but with impaction there may be inversion ; hence the necessity for careful examination. The following are the important differences : Sciatic Dislocation. Frequent in middle life. Result of violence. Slight. Absent. Impaired. Fracture of Femur with Inversion. History. An injury of old age. Often slight violence. Shortening. Well marked. Crepitus. Present unless impacted. Mobility of Limb. Often increased. Inversion of Foot. Inversion is persistent until the dislocation is The foot may at any time become everted by reduced. relief of the impaction. Tuvior. An abnormal tumor may be obscurely felt The upper fragment often fails to move with behind the acetabulum, which moves with the rest of the femur, the rotation of the thigh. Dorsal Dislocation with Eversion. — In the rare instances in which this form occurs the outer branch of the Y-ligament ruptures, and allows the head of the femur to slip inward, thus causing eversion of the foot, instead of inversion, as in the ordinary form of the luxation. Treatment of Backiuard Dislocations. — Prof Bigelow's reduction by manipulation is a great improvement on the older methods (Fig. 58). The patient lies on his back upon a low table, completely anesthetized. Grasp the ankle of the dislocated limb with one hand and the leg below the knee with the other. Flex the leg on the thigh, and the thigh upon the abdomen until it forms a right angle with the surface of the table. Adduct the knee until it is carried over the middle of the sound thigh. Next cause the knee to describe a circle outward and downward until the leg is brought to the table and lies extended by the side of its fellow. What has been done in this maneuver ? By flexion of the thigh you have relaxed the Y-ligament. When you adducted the thigh with outward rotation the head of the bone was lifted over the edge of the acetabulum and it dropped into its normal position. Backward Dislocations below the Ten- don of the Obturator Internus. — If you examine Fig. 56, you will Fig. 58. — Reduction of dislo- cation on dorsum ilii (after Bige- low), 136 SURGICAL DIAGNOSIS AND TREATMENT. SCO the position of the obturator internus muscle. In the ordinary backward dislocations of the femur the head of the bone passes above the muscle. In the variety of dorsal dislocation which we now have to consider it passes bcloiv the muscle ; and this is the important part which the obturator internus plays in luxation of the hip. The bone, having slipped out of its socket and passed below the obturator inter- nus tendon, does so while the thigh is in a flexed position. As soon, however, as the thigh is brought down from this to a straight position, the head of the bone, being firmly held at the trochanter by the Y-liga- ment, slips upward over the tendon, which now winds tightly around* the neck of the ferrjur between the head and the acetabulum. No wonder the old surgeons pulled and dragged with pulleys until they either caused something to break or gave up the fight and called the case one of " irreducible dislocation." Treatment. — The patient lying on his back, proceed as follows : First movement : Carry the knee across the opposite thigh to a position of extreme adduction. Second movement : Sweep it upward horizontally toward the abdo- men. This will allow the head of the bone to come down below the tendon. Third movement : Raise the thigh to a vertical position, and the bone, disengaged from its entanglement with the obturator tendon, will lie in the position of an ordinary backward dislocation. From this point reduction can be effected as described under backward dislo- cation — viz. adduction until the knee is carried over the middle of the sound thigh. Then describe a circle upward, out- ward, and downward until the leg is brought to the table. For-ward Dislocations. — These have a direc- tion downward and inward. Two dislocations are found under this heading : I. Into the Obturator Foramen. — This acci- dent occurs while the person, standing with the thigh abducted and flexed, receives a blow upon the back of the pelvis, or it can be caused by forced abduction alone. The Y-ligament remains untorn, and, as the head of the femur is driven forward and inward, the thigh is flexed and ab- ducted. The symptoms are very characteristic. The patient stands with the injured limb a little in advance of its fellow. There is apparent length- ening, but this is due to a tilting of the pelvis. Measurement may even reveal a slight amount of shortening. The hip is flattened, the adductors tense, and the head of the bone in some cases can be felt on deep pressure (Fig. 59). Treattnent. — Place a towel around the upper end of the thigh, and, while an assistant drawls out- ward upon it at right angles to the middle line of the body, make alter- nate flexion and extension of the thigh upon the body. This is the simplest method, and probably the best. By it the wTiter succeeded in Fig. 59.— Thyroid dis location. INJURIES AND DISEASES OF JOINTS. 137 slip only a little past the This variety is therefore two cases^ — one at the end of eight weeks, and the other after the expi- ration of three months. Another method is as follows : Flex the thigh to a right angle, adduct and make traction at the same time, and then rotate inw'ard while lowering the knee (Fig. 60). 2. On the Perineum. — The bone has to obturator foramen to lodge in the perineum. an exaggerated form of the preceding dis- placement. Flexion and adduction are now more marked, and there may be a slight degree of shortening. Pubic Dislocation. — This occurs usually while the limb is in a position of over- extension, or it may be caused by a fall upon the knees or feet. The bone can occupy one of several positions in the neighborhood of the pubis, but the most common is the ilio- pectineal eminence. The head of the femur Fig. 60. — Reduction of dislocation into the thyroid foramen (after Bigelow), Fig. 61. — Dislocation of head of femur upon the pubes (after Hamilton). cannot only be felt, but even be distinctly seen, in its unnatural position. The toes point outward. There is flexion of the thigh, and if the knee be pressed down upon the table the spine will be found to arch upward in compensation. In backward dislocation the injured thigh lies across the opposite limb, but here the reverse is true, and it takes a direction outward (Fig. 61). The injury most liable to be mistaken for this luxation is fracture of the neck of the femur, yet there need be no difficulty in settling the question. If the patient be anesthetized, the outward rotation can be rectified in fracture, but immobility will be found in dislocation. There is shortening in fracture which can be removed by traction. In almost every case the head of the bone can be distinctly felt in dislocation. Treatment. — First movement : Flex the thigh. Second movement : Abduct the thigh and make traction in the line of the axis of the femur, 138 SURGICAL DIAGNOSIS AND TREATMENT while an assistant at the same time presses the head downward and outward toward the acetabukim. Rare Forms of Dislocation. — Of all cases of dislocation at the hip- joint, the dorsal luxations occur in 50 per cent., the ischiatic in 30 per cent., the obturator in 1 1 per cent., the pubic in 7 per cent. This leaves 2 per cent, of cases in which the bone is found outside any of these regions. One of these is downward upon the tuberosity of the ischium. It is very rare, and when it does occur the displacement is often changed into one of the more common varieties. Thus the bone can slip upward and backward, becoming a dorsal, or forward by adduction and ever- sion, forming a dislocation into the obturator foramen. Treatment. — Flex the thigh and then make traction. Another rare luxation is directly upward (supracotyloid). Only a few cases of this kind have been reported. The symptoms are eversion with abduction. The trochanter is moved upward and backward, and the head of the bone can be felt on deep pressure. Diagnosis between Contusion over the Great Trochanter a}id Dis- location at the Hip-joi)it. — A person suffering from a fall or a blow upon the great trochanter may present some symptoms which are difficult to distinguish from dislocation. The pain may be so great as to render movement impossible ; the limb may be apparently shortened, owing to the patient's trying to find the easiest position. When there is doubt an anesthetic will make diagnosis easy. Motion is then free and normal if the injury is only a bruise, but is restricted in the case of a dislocation. Measurement will show a change in the length of the limb in the case of a dislocation, but none when the injury is a bruise. Palpation will settle the position of the head of the bone. Congenital Dislocation of the Hip. — This is, in the majority of cases, due to arrested development, and the displacement is most com- monly upward upon the dorsum ilii. In some instances the head of the femur is normal, but it is quite common to find the neck shorter and inclined to be horizontal. The ligamentum teres is sometimes thick- ened and stretched, owing to its having to support the weight of the body. In some cases it is wanting or very much atrophied. The acetabulum, although never entirely absent, shows a want of devel- opment. It may be oval and flattened, or it may be small and shal- low, with absence of its cartilaginous rim. The muscles around the hip also exhibit a lack of development. As a result of this dis- location the pelvis undergoes certain changes. The crests of the ilii approach each other, while the tuberosities of the ischii become farther separated. Symptoms. — The dislocation is seldom recognized until the child begins to walk, when a peculiar waddling gait is the first symptom to attract attention, and it is noticed at the same time that the back is very much arched (Fig. 62). The child very easily becomes fatigued, but seldom is there any complaint of pain. By Nelaton's measurement (from the anterior superior spine of the ilium to the tuberosity of the ischium) a displacement of the trochanter upward will be found varying from half an inch to one or two inches. By gentle traction on the leg the trochanter can be brought down, and measurement will show that the leg has thus been lengthened, INJURIES AND DISEASES OF JOINTS. 139 but as soon as the traction is discontinued the trochanter will be found to return to its former position. The two conditions with which this deformity is likely to be con- fused are bow-legs and infantile paralysis. The resemblance to bow- legs is marked in double congenital dislocation. A child with extreme bow-legs has a waddling gait and a tilted pelvis, but the position of the trochanter in relation to Nelaton's line will be found sufficient to settle the question. Infantile paralysis of one leg may bear a close resem- blance to unilateral dislocation, while the laxity of the joint may Fig. 62. — Double congenital dislocation of hip (from a photograph in the collection of Dr. J. E. Moore). closely simulate luxation. But here, again, the position of the tro- chanter in relation to Nelaton's line will settle the diagnosis. Dislocation at the Knee-joint. — Two bones may be dislocated at the knee-joint, the tibia and the patella. The tibia can be dislocated in five directions — forward, backward, outward, inward, and rotary. Forward dislocation is probably the most common. The head of the tibia can be felt projecting in front of the condyles of the femur, w^hile the latter bulge backward into the popliteal space. Numbness is often felt as a result of the stretching of the nerves, and the artery and veins may be seriously injured or even ruptured. Treatment. — Extension, counter-extension, and direct pressure. 140 SURGICAL DIAGNOSIS AND TKEATMENT. Backward dislocation is generally caused by direct violence in the region of the knee. The head of the tibia may be felt bulging back- ward into the popliteal space, while in front there is a corresponding depression immediately below the patella. The leg is in a position of extreme extension, and slopes forward so as to form an obtuse angle with the front of the thigh. The dislocation is frequently compound, and the most serious feature of it is the injury of the popliteal vessels, which, though apparently free from harm at the time of the accident may have their coats so stretched that they give way at a later period, followed by gangrene of the leg. Treatment. — Traction and direct pressure. Lateral luxations are rare and require no special description. Rotary Dislocations. — The only case of this kind seen by the writer occurred to a lumberman whose foot was held firmly in a deep track in the frozen snow while his body swung round upon the limb. The displacement was recognized and reduced by his fellow-workmen. Dislocations of the Patella. — This bone, being freely movable, may be displaced by direct violence, by muscular action, or by both forces combined. The most common displacement is outward. It sometimes happens that the bone is tilted upon its edge (vertical dis- location), and cases are recorded in which the bone was completely turned front backward. The patella being a superficial bone, the diag- nosis presents no difficulty. The dislocation can easily be reduced by relaxing the quadriceps and placing the bone in position by direct pressure. Dislocations of the Fibula. — The upper end of the fibula is rarely dislocated. The most common displacement is outward and forward. It can occur backward and also upward. The displacements are readily recognized, and reduction by direct pressure is easy. At the lower end of the fibula the few dislocations that have been reported were backward. Dislocation of the Ankle. — Examination of the ankle-joint after injury is often a difficult matter. Swelling is likely to be great, and pain so intense that manipulations cannot be borne by the patient. The injuries that must be taken into account are fractures of the lower end of the bones of the leg, fracture of the astragalus, dislocations of the foot from the astragalus, dislocation of the astragalus from the tibia, dislocation of the astragalus alone, sprains of the ankle, and inflammatory disease in the joint. These injuries will at once divide themselves into two great classes, one being attended with deformity, the other without deformity. I. Injuries without Apparent Deformity. — Carefully note the seat of any pain or tenderness. Grasp each malleolus separately and attempt to move it independently of the foot. If crepitus can be felt and the malleolus be found movable, it will be evidence of fracture of the malleolus. If, besides fracture of the lower end of the fibula, there be found increased lateral mobility of the ankle-joint, you may decide that the internal malleolus is broken as well, or that there is laceration of the internal lateral ligament. The injury is Pott's fracture. If you have failed to find any fracture, ask the patient to stand upon the injured foot. Should this cause intense pain, you may suspect INJURIES AND DISEASES OF JOINTS. 141 fracture of the astragalus. Move the foot and you may find deep crepitus ; then your diagnosis may be positive. Should the results of your examination be negative, make careful measurements of the length of the leg, the distance between the heel and the malleoli, also between the malleoli, the tubercles of the scaphoid, and the base of the fifth metatarsal bone. Thus you can detect partial displacement of any of the bones which might not be apparent to the eye. A severe pain behind either malleolus, with swelling and tenderness, should excite suspicion. Examine carefully for the tendons which pass behind these bony prominences. Possibly there is a depression where the tendon ought to be, or the tendon may be felt like a thick cord over the side of the malleolus. If on the inner side, these symptoms will indicate dislocation of the tendon of the tibialis posticus ; on the outer side, that of the peroneus longus. 2. Injuries with Deformity. — The foot is displaced outward or inward. If outward, it is evidence of one of three injuries — viz. {a) Pott's fracture ; \li) Dupuytren's fracture ; (r) Subastragaloid dis- location. If inward, it is also evidence of three injuries — viz. {a) Dislocation of the ankle inward ; {U) Subastragaloid dislocation inward ; {c) Dis- location inward of the medio-tarsal joint. Note carefully the form and position of the heel. If it is elongated or unduly prominent, you are likely to find one of the following : {a) Fracture of lower end of tibia ; {t>) Dislocation of ankle backward ; \c) Subastragaloid dislocation backward. If the heel is flattened, it may be the result of one of three injuries : (a) Dislocation of the foot forward ; {li) Subastragaloid dislocation for- ward ; () arrest of development on one side of the lower jaw ; ic) congenital dislocation. In cases of marked hypertrophy of the tongue constant pressure may produce displacement of the teeth and even dislocation of the jaw. Burns and scalds, followed by extensive cicatricial contraction, may draw the chin or lower lip down to the sternum. Sucking the thumb may cause deformity of the jaw. In the diagnosis of diseases of the jaw it is convenient to divide them into two classes — acute and cJironic. The acute forms are inflammatory, and the most common are abscess of the gums or alveoli and periostitis. When Burns characterized toothache as the " hell of all diseases," he no doubt drew his inspiration from an attack of periodontitis ending in abscess, vulgarly called " gum-boil." The cause of this common affection is suppurating pulp. The diagnosis is easy. There is a his- tory of the characteristic pain of toothache ; tenderness and swelling are felt by passing the finger along the gums. The tooth is elongated and tender on tapping. The face on the affected side is swollen, and finally a collection of pus takes place. If the suppuration is near the surface, it readily finds exit or can be released by simple puncture ; it may find its way through the skin and open about the lower margin of the jaw. Necrosis in that case is a common result. Treatment. — In the early stage the gum may be painted with iodin. Fomentations by means of a small compress of lint or absorbent cot- ton dipped in hot water and repeatedly applied relieve the pain and hasten suppuration. When the pus is near the surface of the gum, simple puncture will suffice ; when deeper a free opening should be made. The tooth causing the trouble should receive the attentions of a dentist and be either saved or extracted. Periostitis or osteo-periostitis is to be diagnosticated when the inflammation spreads over a considerable portion of jaw, attended with high fever, the loosening of several teeth, and excessive tenderness. Chronic Affections of the Jaw. — A chronic affection of the jaw must be necrosis, periostitis, or a tumor. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 1 8/ Necrosis results from tuberculosis, syphilis, a decayed tooth, or a traumatism. It may follow one of the zymotic diseases, and it is common among those who have to breathe the fumes of phosphorus. It is always preceded by severe pain and inflammation. Suppuration takes place, and one or more sinuses result. Through one other of these openings a probe can be made to touch the necrosed bone. If only one sinus exists and the probe is felt to touch a smooth surface, it is likely to prove the root of the tooth. It must be remembered that here, as elsewhere, the external opening may be no indication of the position of the diseased portion of bone. The opening may be on the face, the neck, or even in the nose. Treatment. — While the treatment is the same as for necrosis in other parts of the body, one or two special points must be kept in mind. The sequestrum should be removed, if possible, from the inside of the mouth, and no attempt at detachment should be made until the seques- trum is perfectly loose ; otherwise the soft parts, especially the vessels, may be injured. Chronic periostitis is, as a rule, syphilitic. The common situations are the outer side of the lower jaw and the hard palate. There are generally other indications of specific disease, and, should the surgeon be still in doubt, he can settle the point by putting the patient upon antisyphilitic treatment. Phosphorus Necrosis. — With better attention to the sanitary condi- tions of factories phosphorus-poisoning is much less common than formerly. The disease is usually extensive and its course rapid, so that a patient may apply for advice whose jaw is necrosed to a con- siderable extent without his being aware of it. Diagnosis will depend upon the history and the ordinary signs of necrosis. Tumors of the Jaws. — Epulis ilTii, upon, and doXa, gums) is a mor- bid growth improperly named. Instead of being connected with the gums, it is a tumor growing from the periosteum of the alveolar process and sockets of the teeth. When first recognized it appears to be making its way from about the neck of some particular tooth (Garretson). Simple, Benign Epulis. — The most common form of epulis is that which is connected with the pulp of a tooth, the epulo-pulp-fungoid tumor. It originates in the exposed tooth-pulp, and by gradual increase covers the gum adjacent to the affected tooth. After a time it ulcerates and discharges a sero-purulent fluid, or it may undergo ossification. Another variety of epulis is the erectile or nevoid. Both of the foregoing are simple and benign in character. Malignant Epulis. — Malignant epulis begins like the benign forms, but its rapid growth, its vascular character, its purplish color, and its tendency to form a fungous mass protruding between the teeth and bleeding on the slightest provocation reveal its serious nature and demand its radical removal. Treatment. — The benign forms require the removal of the involved tooth and the portion of the alveolar process which forms its socket. The malignant epulides must be dealt with as cancerous tumors. Not only the socket, but a portion of the jaw, must be removed. The doomed section of the maxilla should be sawn through by two vertical cuts, and the intervening portion removed by strong forceps. 1 88 SURGICAL DIAGNOSIS AND TREATMENT. In the diagnosis of tumors of the jaws the first question to settle is whether a gi\en tumor is cystic or sohd. Cystic tumors are not un- common in this situation. A cystic tumor is smooth, and rises above the surrounding bone by gradual elevation. Fluctuation may be detected in tiie growth, or the bony cyst- wall may crackle like an egg- shell under the pressure of the fingers. When these conditions are found, examine the teeth at that part and in all probability you will find one tooth missing. Or it may be that the deciduous tooth at that point has never been cast off. These tumors are liable to be mistaken for malignant disease of the bone, but the surface is perfectly smooth, the patient is generally )'oung, and the growth is painless ; all of which argue against malignancy. When this smooth tumor is cut down upon, the thin bone readily gives away and a cavity is opened up. Explore this cavity, and out will pop a tooth which lay loose in a thick mucilage-like fluid or perhaps turned upside down. Even when crack- ling is absent the smoothness of the tumor should arouse suspicion, and this will be confirmed by finding that one of the permanent teeth has never been cut. It is a good rule never to remove a tumor of the jaw without first cutting into it. While these dentigerous cysts are mostly confined to young persons, too much stress must not be laid upon that point. In a case upon which I operated a short time ago the tumor was smooth and apparently as hard as ivorj- ; there was no crackling, and the patient was fifty years of age. The tumor contained a large molar tooth. The cyst can be reached by an external incision, but when practi- cable an opening from the inside of the mouth will prove just as satis- factory, and has the advantage of leaving no disfiguring scar. Another form of cystic tumor common in the lower jaw is irregular and lobulated. This is imdtilocitlar cyst, which in the majority of cases is a cystic degeneration of a sarcoma or carcinoma. Total extirpation is the only treatment. Solid Tumors of the Jaws. — These are naturally classified as benign and malignant. In the diagnosis of solid tumors of the jaw begin by examining the face, mouth, and nose. The consistence of the tumor should be felt by first placing the fingers outside the cheek and rolling the skin over the growth ; then the fingers should be placed in the mouth and a bimanual examination made. Having satisfied yourself of the con- sistency of the tumor, pass the fingers over the hard palate and back- ward over the soft palate to the posterior nares. The nostril will require careful examination, and this can be carried out by throwing a strong light into it and testing any suspicious growth with a probe. If in this examination a growth is found attached to the turbinated bones, it is a polypus. A tumor in the antrum will also show itself in the nostril, but at the same time there will be expansion below the eyelid and perhaps protrusion of the eyeball. The non-malignant tumors are the following : I. Fibromata. — The growth of these tumors is slow, and they are generally painless. They start from the periosteum, and especially from the periosteum of an alveolus, which renders these growths liable to be mistaken for epulis. When they arise from the periosteum the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 1 89 growth is smooth or lobulated, firmly attached to the bone, and freely- movable over the surrounding parts. When the endosteum is the starting-point the tumor gradually expands the jaw, and if allowed to grow attains an enormous size. If the growth is in the upper jaw, the antrum or nasal fossae are apt to be encroached upon. We recognize pressure upon the antrum by observing the following points : The outer wall of the antrum below the orbit bulges forward. If the floor of the orbit is pressed upon, the eyeball protrudes. Examination by the mouth will show that the roof of the mouth is flattened or depressed. 2. Enclwiidromata, or cartilaginous tumors, are not common. They are more rapid in their growth than fibromata, are much harder, and 111 Fig. 90. — Recurrent ossifying enchondroma (Heath). are more nodular (Fig. 90). The lower jaw and the antrum are favorite situations. 3. Ostconiata, or osseous tumors, are still more rare. They are harder even than the cartilaginous tumors, and may take the form of exostoses or may present the appearance of a general thickening of the whole bone. Treatjnent. — Fibromata, enchondromata, and osteomata should all be treated by thorough removal of the growths. The enchondromata are apt to recur after removal. Malignant tumors are — I. Carciiioinata. — Primary cancer of the jaw is rare. The majority of cases are those in which the disease spreads from the nasal mucous membrane or from the palate (Fig. 91). In either case great destruction of tissue may take place without any marked tumor being developed. A probe passed through a small external opening may reveal a large cavity, while there is no evidence of a cancerous mass by external appearances. Three characters of malignant tumors must be kept in mind — viz. rapid growth, destruction of bone, and fungation into the 190 SC-A'G/C.IL 1)/AGA'0S/S AND TREATMENT. inoutli. Fibrous, cartilaginous, and osseous tumors are slow in grow- ing ; thc\- are hard to the touch, they do not affect the general health, and are painless, and, except when they exert pressure upon neighbor- ing parts, they do not involve the surrounding structures. Carcinoma is soft and has a tendency to fungate. It is painful, soon telling on the general health of the patient, and involving adjacent structures, espe- cially the lymphatic glands. Fungation is strongly characteristic of cancer. It must be borne in mind, however, that benign tumors, par- ticularly of the lower jaw, may in the course of time break through the skin and form a fungating mass. This, however, is slow of growth, Fig. 91. — Epithelioma of the left malar and superior maxillary (Heath). as was also the tumor which gave rise to it, and it is more healthy in appearance than a cancerous fungus. 2. Sarcomata. — The round-celled or medullary sarcoma is found most frequently in the upper jaw, and bears a close resemblance to medullary cancer. Its leading characteristics are rapidity of growth, softness, and tendency to fungate. In the majority of cases the disease begins in the antrum. As the tumor increases in size it produces symp- toms which vary according to the direction taken by the growth. The projecting mass may show on the cheek, causing closure of the nasal duct, producing epiphora and edema of the eyelids. In other cases the growth takes a direction inward, and forms fungous masses in the nose or mouth. Sometimes the disease starts in the hard palate, the alveolus, or the nose. The difficulty here is to diagnosticate between cancer, nasal polypus, and the results produced by decayed teeth. Practically, the diagnosis between carcinoma and sarcoma is of slight importance, as the treatment is the same for both. For purposes of treatment it is sufficient to decide that the tumor is malignant, leaving the histological characters to be decided after removal of the crrowth. Yet there are INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 191 certain clear distinctions to be noted. Sarcoma involves the neighbor- ing parts, but not the glands, while carcinoma readily spreads to the glands. The spindle-celled variety of sarcoma has a tendency to spread along the periosteum, and becomes softer and softer with each recurrence. Probably the greatest difficulty lies in distinguishing between malignant tumors and inflammatory processes. A sarcoma is so similar to an abscess as to puzzle the most experienced. Yet there is an absence of the inflammation and pain which always precede an abscess. A collection of pus due to the carious root of a tooth would show a history of toothache with evidence of dental caries. The probe is not always a sure guide. If roughened bone be felt, it is not necessarily necrosis, for the bone can be laid bare in the same manner by the ravages of carcinoma or sarcoma. Tiratinciit. — Malignant tumors of the jaw can only be dealt with in one way — complete removal. Within the last few years reports of cases alleged to have been cured by injections of the toxins of ery- sipelas with bacillus prodigiosus have appeared in the medical journals. In several cases I have given this method of treatment a most patient and careful trial, but in every instance with disappointing results. For the present, at least, our hope must lie in the direction of early and complete removal. Recurrence is the rule, even where the whole of the lower jaw is taken away. Operation on the Upper Jaw. — Small tumors confined to the alveolus can readily be removed by strong cutting bone-forceps, without any external incision. Tumors of considerable size have also been extirpated in this manner, although the difficulty of deliver- ing the tumors through the mouth has sometimes been so great as to necessitate an incision of the angle. Large tumors involving a con- siderable portion of the bone require resection of the entire jaw. The method is as follows : First Step. — An incision is made along the infraorbital ridge from the malar bone to a point just below the inner canthus, thence along the side of the nose around the ala to the middle line, and lastly through the middle line of the upper lip. The flap formed by these incisions is dissected from the bone and turned outward, divided vessels are ligated, and hemorrhage arrested by pressure with hot sponges. Second Step. — The incisor teeth on the affected side are next remov^ed, a narrow-bladed saw passed into the nostril, and the hard palate and alveolus divided. With a Hey's or other suitable saw sec- tion is made of the malar bone in a line with the spheno-maxillary fissure and also of the nasal process of the upper jaw. The saw can be supplemented, if necessary, with bone-forceps. Powerful forceps, preferably Fergusson's lion-forceps, are next made to grasp the jaws, and by a powerful wrench the bone is separated from its con- nections, and when quite loose the infraorbital nerve and soft palate are severed with a knife. Should any diseased tissue still remain, it can be removed with gouge and chisel. After ligating any spurting vessels the cavity can be filled with hot sponges for a few minutes and all hemorrhage arrested. The flap is now replaced, and the incision accurately closed through its whole extent with sutures of catgut, except the lip, where silkworm gut is perhaps more reliable. The 192 SURGICAL DIAGNOSIS AND TREATMENT. cavity of the check is filled with iodoform gauze, and an external aseptic dressing, retained by a light flannel or gauze bandage, completes the operation. Even before the advent of antiseptic surgery wounds of the face healed readily by first intention, and these operations were wonderfully free from mortality. With careful asepsis and the use of disinfectant mouth-washes the progress of recovery is rapid, and the sufferings of the patient are reduced to a minimum. When the disease is not so extensive as to require removal of the whole jaw a shorter incision is demanded. Division in the middle line of the lip and down to the ala of the nose may be sufficient. When the orbital plate is not involved, the saw can be made to cut horizontally below it, and the palate when healthy may be spared by making the saw-cut immediately above it. Both upper jaws have occasionally been removed. Probably the best of the methods adapted for this formidable operation is that employed by Mr. Dobson of Bristol,' who in 1872, in a woman of fifty-two, divided the lip in the middle line and carried the incision up each side of the nose. Operations on the Lo^wer Jaw. — When the tumor is small and involves only the alveolus, it can be removed with bone-forceps. If the mucous membrane covering the lower jaw be freely divided, a great portion of the bone can be removed without any external incision. In extensive disease it may be necessary to remove one-half or the whole of the bone. When an external incision is necessary, it can be made just below the lower border of the bone with a division of the lower lip in the middle line ; but this later incision is not always necessary. After separating the bone from the soft parts the jaw is divided in the middle line and strongly drawn outward, while the soft parts are separated back to the articulation, and the bone disconnected at the jaw by dividing the ligaments with knife or scissors. The question of saving the periosteum cannot be entertained if the disease is malignant, but in non-malignant tumors and in necrosis this membrane should be carefully preserved. All bleeding points being secured by ligature, cautery, or pressure, the incision is accurately closed and an external dressing applied. The after-treatment consists in giving fluid nourishment by a tube, and keeping the mouth thoroughly disinfected by detergent washes, of which the glycerinum acidi car- bolici applied with a camel's-hair brush, as recommended by Heath, is one of the best. Diseases of the Tempore -maxillary Articulation. — This is one of the few joints which escape tuberculosis, but it is liable to rheumatic arthritis, and one or both sides may be the seat of the disease. It is chronic in character, and may result in absorption of the inter- articular cartilage and in outgrowths from the bone. True ankylosis does not take place. This disease is readily diagnosed from its painful and chronic character, and from the protrusion of the chin either directly forward or to one side according as the disease affects one or both articulations. Acute inflammation is the result of injury, or it may be the exten- sion of the inflammatory process from the ear or some neighboring 1 Brit. Med. Journ., 1873. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 1 93 part. It then follows the course of arthritis in other parts, and should suppuration take place ankylosis is not an unlikely result. Closure of the jaws may be temporary or permanent. The tem- porary closure is usually reflex in origin, due to the irritation produced by the cutting of a wisdom tooth or the failure of a tooth to appear, owing to want of room or to an abnormal position. Some of the cases are hysterical. Permanent closure may be due to ankylosis following suppurative arthritis. Another frequent cause is cicatrization following ulceration or injuries of the mucous membrane of the cheek ; and often through profuse salivation the lower jaw becomes closely bound to the upper, so that the teeth cannot be separated sufficiently to admit solid food. Sometimes the gums are adherent, especially if there is necrosis of the alveolar process. Treatment. — When there is complete ankylosis or intractable closure the operation of Esmarch is probably the best. It consists in the formation of an artificial joint in front of the contraction, and admits of at least limited motion of the jaw. It simply consists in the removal of a piece of bone of a w^edge shape in front of the masseter muscle. Diseases of the Tonsils. The tonsils are subject to the following diseases : tonsillitis, hyper- trophy, calcareous and cheesy concretions, sarcoma, and carcinoma. Tonsillitis, popularly called quinsy, is readily distinguished from other diseases. It is an acute, local, inflammatory affection, generally following exposure to cold, but depending upon a more remote cause, such as a tubercular or rheumatic diathesis. The onset of the attack is marked by pains in the limbs, difficulty of swallowing, chills, and general malaise. The temperature rises quickly, and may reach 104° or 105° F. If the throat be examined at this stage, one or the other tonsil will appear swollen and violently inflamed ; the redness extends to the fauces, and the glands beneath the angle of the jaw are swollen and tender. By degrees swallowing becomes more and more painful. To add to the patient's discomfort, large quantities of mucus and saliva are constantly being secreted and must be expectorated. Speech is at first changed to a nasal twang, and later may be almost lost, and when the patient attempts to swallow fluids they run out of the nose. If resolution does not take place (which it happily does in many cases about the third or fourth day), suppuration occurs, and about the ninth day the abscess ruptures, and the patient, experiencing immediate relief, speedily recovers. Sometimes the second tonsil becomes affected, and then the swell- ing is so great as almost to close the throat. When both are affected at the outset, it is strong presumptive evidence that the attack is due to a septic cause. Treatment. — At the outset a brisk purgative should be giv'en, and 10 minims of tincture of belladonna every three hours. If, after forty- eight hours, the inflammation still progresses, the case will probably go on to suppuration. A hypodermic of morphin with atropia, given at bedtime, will give great relief and arrest the secretion of the sticky mucus which is so distressing. The formation of pus and the pointing 13 194 SURGICAL DIAGNOSIS AND TREATMENT. of an abscess slunikl not be waited for. An early incision which freely opens up the tonsil will anticipate the abscess and cut short the disease by several days. In lancing the tonsil use a strai^^ht, sharp knife, wrapped round with adhesive plaster to within an inch of the point. The incision, if kept within the line of the molar teeth, will run no risk of woundiiiL^ the internal carotid artery, and, as the parts are so sparint^ly supplied with nerves, the operation is practically painless. Follicular tonsillitis is recot^nized by small, yellowish-white swell- ings about the size of a pea which cover the surface of the tonsil. As these little abscesses burst they form ulcers, which may run together and produce large ulcerated patches with edges swollen and under- mined. Hypertrophy is a result of repeated attacks of acute tonsillitis. It ma\', however, be due to a chronic catarrhal affection of the tonsil. Tuberculous children are specially liable to this affection. The enlarge- ment can be readily seen when the patient opens the mouth, and in some cases the glands almost touch each other. Respiration is inter- fered with, especially during sleep, the child sleeping with the mouth open and breathing in a noisy and unpleasant manner. There is usually no pain, unless there be attacks of acute inflammation ; the enlargement is slow and steady. Treatment. — Excision of the tonsil is the only effective remedy. For this operation several tonsillotomes have been invented, of which Mathieu's is perhaps the best (Fig. 92). An assistant should steady Fig. 92. — Mathieu's tonsillotome. the patient's head, and with his fingers below the angle of the jaw- press the tonsils inward. The instrument is applied (taking care that the lower portion of the tonsil lies well within the grasp of the instru- ment), and with a rapid movement the required portion of the gland is removed. Bleeding has often proved troublesome after removal of the tonsil, the hemorrhage coming from the tonsillar branch of the facial. To arrest it, pressure should be made from the inside with a piece of gauze held in a pair of forceps while the fingers make pressure from without. In this way the tonsil can be compressed so as to control the flow of blood, and this can be further aided by the application of strong astringent solutions, as the tincture of perchlorid of iron. It is rarely that ligation of the carotid has to be resorted to. Calcareous and cheesy concretions are found of various sizes, sometimes large enough to increase the size of the tonsil to an enor- mous extent, or so small that they are only accidentally discovered when the tonsil is excised. Besides the discomfort caused by their size, concretions often cause inflammation of the tonsil. Treatment. — Remove the concretion by cutting down upon it and turning it out of its bed, or by removing the redundant portion of the tonsil in which the concretion is lodged. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 1 95 Tumors of the tonsil are rare, the form most hkely to be met with being sarcoma. Sarcoma occurs in young persons, usually below twenty years of age. It forms a tumor which steadily increases in size and soon begins to ulcerate, death often resulting from hemorrhage. The growth forms a well-defined tumor which does not involve the neighboring glands. This feature distinguishes it from carcinoma. Carcinotna of the tonsil is of the epithelial variety. It is seldom found as a primary affection, but as an extension from the disease in adjoining organs it is not uncommon. In the early stages a primary cancer of the tonsil is difficult of diagnosis, and is generally set down as a simple hypertrophy of the gland. As the disease progresses, how- ever, the lymphatics become involved, nodules form about the angle of the jaw, and the general characters of carcinoma become manifest. Treatment. — Unfortunately, even the total extirpation of the tonsil is unsatisfactory for either form of malignant disease, as the growth is almost sure to return. In sarcoma, the tumor being more sharply defined and the neighboring parts free from disease, the prospect of cure is better. The tonsil can be removed, either by the mouth or by an external incision extending for about three or four inches along the anterior border of the sterno-mastoid muscle, beginning at the ear and ending below the level of the tumor. If necessary, a second incision may be made along the lower border of the jaw. Dissecting through this space, the tumor is reached, lying within the superior constriction of the pharynx. A more radical operation, however, is necessary, and the method devised by Czerny is probably the best. After a pre- liminary tracheotomy he makes an incision from the angle of the mouth to the anterior border of the masseter muscle, and from this point downward to the os hyoides. Mikulicz makes his incision from the mastoid process to the greater cornu of the hyoid bone. In either operation the lower jaw is divided about the position of the first molar tooth, and turned backward so as to give room for the deep dissection. The Pharynx. The diseases of the phar>mx requiring special attention from a diagnostic standpoint are retropharyngeal abscess and tumors of the pharynx. Retropharyng-eal abscess is, in many cases, a result of caries of the cervacal vertebrae. It may, however, occur as a sequel of scarlatina or as an extension of inflammation from neighboring parts, especially the glands. It is most commonly met with in tubercular children. The first symptoms to attract attention are difficulty of swallowing and dyspnea. If the patient be subject to disease of the cervical vertebrae, these symptoms are almost certain to indicate an abscess between the back of the pharynx and the cervical vertebrae. Examine the patient's mouth, and you will find projecting from the back of the pharynx, usually to one side of the middle line, a swelling which fluctuates, is soft and boggy, and does not disappear on pressure. The patient in some cases cannot move the head without intense pain, but this is due to disease in the vertebrae. As the abscess increases in size it extends 196 SURGICAL DIAGNOSIS AND TREATMENT. laterally, and if allowed to go untreated causes a bulging in the neck just behind tiie sterno-mastoid muscle. Rarely it burrows into the posterior mediastinum. Trcatnioit. — As soon as the presence of pus is determined an open- ing should be made into the tumor. The patient's head being steadied by an assistant and held slightly forward, depress the tongue, and with a long straight bistoury make an incision near the middle line into the abscess. The bodies of the cervical vertebrae lie directly behind, so that there is no danger of cutting any important structure. If the abscess is large, and there is danger of suffocating the patient by too rapid an outflow of pus, an aspirator can first be used to remove a suf- ficient quantity to lessen the swelling, after which the abscess can be laid freely open with a knife. When the abscess is of old standing and points in the neck behind the sterno-mastoid, it can be opened externally. An incision is made through the skin at the bulging point, and, after the manner of Hilton, a grooved director, followed by dressing-forceps, is pushed into the abscess and the opening freely dilated. It should then be thoroughly irrigated and dressed in the usual manner. This method is in many ways preferable to the opening on the inside, as it allows external drainage and averts the unpleasantness of pus discharging into the mouth. Tumors of the pharynx are rare. In most cases the growths are congenital, and may be papillomatous, fatty, or fibroid in character. If the tumor pulsates, it is likely to prove an aneurysm of the internal carotid artery. Diagnosis of Diseases and Injuries of the Esophagus. The following are the conditions to be sought for in an examination of the esophagus : Malformations. — Branchial fistuL-e may occur at any of the three positions which correspond to the branchial clefts of the embryo. The lowest of them is at the sternal end of the clavicle ; the middle, opposite the thyroid cartilage ; and the highest, between the thyroid cartilage and the hyoid bone. A permanent congenital fistula existing at one or more of these points may be set down as a branchial fistula. Such fistulje may be capable of admitting nothing but a probe, though the external opening may be much larger farther in, and may expand to the dimensions of a good-sized cyst. When pressure is made along the course of the fistula a mucous fluid is found to exude. Sometimes it suppurates and gives rise to a constant discharge of pus. Pouches, or diverticula in the esophagus, with stricture, are some- times congenital. An infant may be found to suck well, but the milk, instead of being swallowed, runs out of the mouth. As the child receives no nourishment, emaciation rapidly follows. An important symptom of dilatation above a stricture is the regurgitation of large quantities of milk at a time, and the evidence that the milk has never reached the stomach, not being curdled nor of acid reaction. Stricture of the esophagus may be spasmodic, cicatricial, malig- nant, or due to the pressure of a tumor. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. l^'j Spasmodic stricture is met with in young or middle-aged women of hysterical temperament. The patient complains of a sensation as if a ball were rising in her throat, the so-called " globus hystericus." The difficulty of swallowing comes on suddenly without any perceptible cause, and it may be that the dysphagia is confined to certain articles of food, or the patient may swallow perfectly when unobserved. Pass a bougie down through the esophagus, and it will be found to reach the stomach without obstruction. Fibrous or cicatricial stricture has a well-defined cause. A child gets hold of some lye or other caustic liquid and drinks it, severely burning the mouth and digestive tract. In the process of healing the tissues contract, and the esophagus at one or two points becomes almost closed. The most common seat of such stricture is at the level of the cricoid cartilage ; that is to say, at the beginning of the esophagus. The history of these cases is usually very clear and the diagnosis not difficult. Food is taken into the mouth, passes beyond the pharjmx, but sticks in the gullet and soon returns. The patient is emaciated and undeveloped. In the diagnosis of stricture due to any cause the passage of the bougie (Fig. 93) gives the most satisfactory information. It is done as Dilators for esophageal stricture. follows : The patient, seated in a steady chair, holds the head well back so as to bring the mouth and esophagus in line. The bougie, moistened with hot water, is passed to the back of the pharynx, and while the patient attempts the act of swallowing, it is pressed gently into the esophagus. Should resistance be met with, no force should be used, but the instrument withdrawn and gently pushed in another direction. Bougies of different sizes should then be employed, in the hope that one can be made to pass through the stricture and into the stomach. Many forms of bougie have been invented. Those most commonly employed consist of whalebone stems upon which ivory knobs of dif- ferent sizes can be screwed. Malignant or cancerous stricture is found in persons about or after the period of middle life, and more frequently in men than in women. The symptoms develop slowly. The difficulty of swallowing comes on by degrees — first as regards solids, and later liquids. Pro- gressive emaciation is noticed, and there may be a slight discharge of bloody mucus and pus. In cases of this kind the glands of the neck should be carefully examined, and a systematic search should be made for cancer in other organs. The passage of bougies, if resorted to at all, must be done with great care, lest they greatly aggravate the dis- ease. There is another diagnostic method which is perfectly harmless and generally reliable. This is auscultation. If the patient be asked 198 SURGICAL DIAGNOSIS AND TREATMENT. to take a mouthful of water, and the stethoscope be placed over the lower third of the esophagus, the fluid can be heard to trickle through the stricture. The esophagoscope is an instrument that may sometimes be employed to advantage in the diagnosis of stricture, carcinoma, and foreign bodies in the esophagus. It is an endoscopic instrument which can be passed through the pharynx and down the whole length of the gullet. An electric-light attachment illuminates each part as it comes into view. Considerable experience and dexterity are required in its management. Trcatiiiciit. — Several methods of treating stricture of the esophagus are practised : 1. Dilatatio)i by Bougies. — When the stricture is simple and not very rigid the passage of the largest bougie which can be inserted is daily employed, and the size increased as the stricture dilates. The patient is fed on liquids, milk, eggs, strong broth, etc. In many cases the esophagus above the stricture is sacculated, rendering it impossible to pass instruments from above. 2. Retrograde dilatation was first performed by Von Bergmann in 1883. The first step of the operation deals with the stomach, and is either a gastrotomy or a gastrostomy according to circumstances. The gastric opening should be large enough to admit one or two fingers besides the dilating instruments. A larger opening is unsafe, as it allows leakage of the stomach-contents into the peritoneal cavity, while too small an opening makes it difficult to find the cardiac orifice (Woolsey). The second step is the dilating of the stricture. With the fingers in the stomach opening find the cardiac orifice, and guide a strong uterine, pharyngeal, or Otis dilator up through the stricture and stretch it. Instead of dilators, it may be more expedient to use other methods in stretching the strictured part. A thread can be swallowed to the end of which is attached a shot, or a knot can replace the shot. By means of this thread bougies can be pulled up from below. Abbe followed a plan in his second case which appears to answer the pur- pose admirably. After opening the stomach the stricture was dilated as much as possible in the manner just described. He then by means of a " string saw " cut the remaining tissue, so as to admit of complete dilatation. The wounds were closed, and after a few days bougies were passed from above. Bernays employs a " rosary bougie," made by taking the olivary bulbs from the ordinary whalebone bougies, and, after perforating them in their long axes, he threads them on strong silk. The smallest size is placed at the upper end of the chain, and kept from slipping by a knot on the thread. By regular gradation the size is increased to the largest bulb that can be used. Treatment of Malignant Strictiirc. — For obvious reasons the use of dilating bougies is not suitable in malignant stricture. Two methods are left to us, the one dealing with an artificial opening, the other with the wearing of a tube to keep the stricture permanently dilated. Excision of the growth has been resorted to, but the cases where such treatment is available are few and far between. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 1 99 Esophagostomy is the operation of making an artificial opening in the esophagus. It of course must be made below the stricture, and, as it is impossible to prove how far down the esophagus the disease extends, the operation is very unsatisfactory. The incision is the same as for esophagotomy, only lower down. When an artificial opening has to be resorted to, the stomach offers the best field, as it is farther from the disease and is comparatively easy, and yet the results of gastrotomy for malignant disease are exceedingly bad. Like all operations which aim only to relieve, and not to cure, it can never be looked upon with favor. This, however, it will do — it will (particularly if resorted to before he is exhausted) allow the patient to receive nourishment and prevent starvation, and lessen the suffering which attends ev'ery attempt to pass food along the esophagus. Of the many methods of performing gastrostomy, that of Witzel is probably the best. In this operation the fistula is made to pass through both the rectus and transversalis muscles. As the fibers of the muscles run at right angles to each other, their contraction may be relied upon Fig. 94. — Witzel's method for gastrostomy, showing application of sutures in wall of stomach, imbedding tube obliquely therein. Fig. 95. — Sutures tied, completely im- bedding tube for some distance. as an efficient sphincter. The second important feature of this ope- ration is the enfolding of the tube in the wall of the stomach, the stomach-wall being stitched over the tube so as to form an oblique cone (Figs. 94, 95). The Ssabanejew-Frank operation may be preferred by some ope- rators. It consists in drawing up a cone of the stomach through the ordinary Fenger incision and under a bridge of skin to a point above 200 SL.RG/CAL D/AGA'OS/S AND TREATMENT. the border of the ribs, where it is fixed and opened. This secures a curved fistula with a bridge of stretched skin acting as a sphincter (Figs. 96-99). P^GS. 96-99. — Frank's method of gastrostomy in carcinoma of the esophagus. As an improvement upon any of the foregoing methods Symonds has invented tubes which can be passed down to the stricture, and, fitting accurately there, liquids can be passed through without difficulty. The tubes are from 4 to 6 inches in length, made of gum elastic upon a silk web, and having a highly polished surface within and without. At the upper end the tube is funnel-shaped to rest upon the stricture, and slightly flattened anteriorly to fit the more accurately against the cricoid cartilage. Two perforations in the rim of the funnel are for the attachment of a silk thread. In the introduction of the tube the stricture is first accurately located and its position indicated on the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 20I bougie. With a whalebone guide the tube is slipped very gently down to the stricture, and through it until the funnel meets with resistance. The guide is withdrawn, and the silk thread which is attached to the funnel is then made fast to the ear or secured to the cheek with adhe- sive plaster. After two or three days it will be found that a larger tube can be inserted as the stricture dilates. The second and larger tube may be left in position several months. II. DISEASES AND INJURIES OF THE ABDOMEN. Examination of the Abdomen. — For this examination the patient should lie upon a firm table or bed, the head and shoulders should be slightly raised, and the knees flexed to an angle of about ninety degrees. This posture relaxes the abdominal muscles suf- ficiently. If the head and shoulders be raised too high, the antero- posterior diameter of the abdomen will be increased and it becomes more difficult to palpate the organs. The abdominal cavity includes everything within the peritoneum, and for diagnostic purposes it is convenient to consider the abdominal and pelvic regions as one cavity. The anterior wall of this cavity is lozenge-shaped, the four corners of the lozenge being at the ensiform cartilage, the pubes, and the loins. This wall is composed of skin, fat of indefinite thickness, muscles, fascia, and peritoneum. In our examination it lies between us and the structures within, rendering palpation difficult, and by the contraction of the muscles presenting appearances which are likely to mislead. Patients wath thin, lax abdominal walls are easily examined. The most difficult subjects are males whose abdominal walls are thick and fat. It is customary to divide the abdomen into nine regions. This is done by drawing upon the skin two vertical and two horizontal lines. The vertical lines e.xtend from the middle of Poupart's ligament to the cartilage of the eighth rib. The upper transverse line is at the level of the ninth costal cartilage, and the lower at the highest point of the crest of the ilium. Beginning from above downward, w^e have thus mapped out, in the middle, the epigastric, umbilical, and hypogastric regions ; on the right side, the right hypochondriac, the right lumbar, and the right iliac ; on the left side are the left hypochondriac, lumbar, and iliac. The contents of these regions are as follows : In the epigastric region are found, from before backward, the left lobe of the liver; part of the anterior wall of the stomach with the cardiac and pyloric orifices ; the gastro-hepatic omentum and foramen of Winslow. Close to the foramen are the hepatic artery, the hepatic and cystic ducts, and the origin of the ductus communis choledochus, the portal vein, and the vagus. Behind the stomach lie the duodenum, the pancreas, the celiac axis, the superior mesenteric artery, the solar plexus, the aorta, and the vena cava inferior. The right hypochondriac region is occupied by the right lobe of the liver, behind which is the gall-bladder, a small portion of the transverse colon, and the upper end of the right kidney with its suprarenal capsule. The left hypochondriac region contains the cardiac end of the stomach, the spleen and gastro-splenic omentum, the left flexure of the colon, the upper end of the left kidney, and its suprarenal capsule. 202 SL.KC/C.1L n/A GNOSIS AXD 'JKKATMEN7\ The umbilical region is occupied by the bulk of the small intestine, the great omentum, mesentery, aorta, and vena cava inferior. The lumbar regions contain the ascending colon on the right, the descending colon on the left, the right and left kidney respectively with their ureters, some loops of small intestine, and ccllulo-adispose tissue. The hypogastric region contains the great omentum, portions of the small intestine, the bladder when distended, or the uterus when enlarged. The iliac regions contain on the riglit side the cecum, and on the left the sigmoid flexure. Subjective Symptoms. — The patient suffering from disease or injury in the abdomen may complain of pain, fulness, weight, distention, burning, or undue motion. Of these pain is the most important and most frequently met with. It may be sudden in its onset, as in colic, or it may be chronic, as in gastric carcinoma. We can form a fairly reliable opinion of the nature of a case from the character of the pain as described by the patient. Position of the Pain. — As a rule, when pain is referred to one par- ticular part it indicates disease in the organ or structure which is the seat of pain. Care must be taken to differentiate between pain in the abdominal wall and in the internal organs. If the skin is affected, the pain is sharply localized ; there is tenderness to touch, and there may be redness, showing erythema, ulceration, erysipelas, etc. Pain in the nerves is generally neuralgic ; there is usually tenderness at one or more points ; it has a sudden onset and an equally sudden disappear- ance, and there is absence of fever. Herpes zoster is attended with vio- lent pain before the appearance of the vesicular eruption. Disease of the vertebrae or the pressure of an aneurysm on the spinal column pro- duces a pain which is intermittent in character, and is felt in the middle line between the ensiform cartilage and the umbilicus. When the mus- cles and fascia are affected the pain increases with motion of these muscles, as in coughing, laughing, or bending the body. Sudden pain occurring in paroxysms, attended with vomiting, rapid pulse, cold sweats, pallor of the skin, and more or less collapse, is sug- gestive of intestinal, renal, biliary, or uterine colic. If it occur in the course of typhoid fever or ulceration of the stomach or intestine, it is very suggestive of perforation and escape of the contents of the hollow viscera into the peritoneal cavity. The rapid development of peri- tonitis would confirm the suspicion. But the severity and suddenness of the pain must not be explicitly relied upon. Such pain is found in simple gastralgia, enteralgia, or obstruction of the intestine. These will receive closer attention when respectively dealt with. Pain over the whole abdomen is generally caused by peritonitis or rheumatism. If peritonitis, there is great tenderness on pressure, the limbs are drawn up to relax the abdominal walls, and the weight of the bed-clothes cannot be borne. Rheumatism is recognized by the slight amount or absence of fever, by the aggravation caused by movement, by the presence of uric acid and urates in excess. Fulness, weight, and distention are subjective symptoms of minor importance, due to enlargement or displacement of the various organs, the presence of tumors, or the presence of inflammation. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM 203 Objective Symptoms. — An examination of the abdomen embraces inspection, palpation, percussion, auscultation, and, in exceptional cases, exploratory puncture or exploratory incision. Inspection. — Stand at the patient's feet, and as he lies in the posi- tion already described any changes in form or contour can be readily noted. The size and shape of the abdomen are the first to be considered. In children the abdomen is naturally more protuberant and proportionally larger than in adults. Large eaters have large bellies, and some peo- ple have their abdominal walls and omentum enormously thickened with fat. When due to such conditions the abdominal enlargement is proportionate to the enlargement of other parts of the body, while in ascites or tumors the size of the abdomen strongly contrasts with the wasted condition of the chest and limbs. Ascites is characterized by general enlargement, and the contained fluid gravitates to the flanks, causing them to bulge outward, while the anterior wall is flattened. Change of position will be followed by cor- responding change in shape, the upper parts becoming flattened, while the lower bulge. In excessive distention from ascites these signs do not hold good, for all parts are tense ; the swelling is uniform and unchanged by posture. Accumulation of gas in the intestine is an important symptom. It may be due to simple indigestion, and in such a case is usually of slight importance. It is an accompaniment of typhoid fever. Surgically, it is met with as one of the alarming results of peritonitis following opera- tions or as the effect of obstruction in the large intestine. Large tumors of especial organs, as the spleen, liver, or gall-bladder, may, on inspection, present the appearance of general enlargement of the abdomen, but further examination by palpation and percussion will locate a tumor in the position to which it belongs unless it is so large as to fill the abdominal cavity. Local Enlargement. — When we observe a local enlargement of any part of the abdomen, our attention is naturally drawn to the organ or organs which normally occupy that position. And this is a pretty safe rule, for a tumor of any organ always begins to grow in the normal position of that organ, and encroaches by degress upon the neighbor- ing regions. Thus a tumor of the kidney may be felt in the umbilical region, but its first appearance is in one or the other lumbar space, and it never reaches the umbilical until it has filled the lumbar region. The color of the skin is not very suggestive. In ascites and edema it is pale and glistening ; in Addison's disease there may be an areola ; in pregnancy there is not infrequently a bronzing of the skin between the pubis and umbilicus. Enlarged veins may be easily perceptible beneath the skin, as in cirrhosis of the liver or in cases where a tumor exists large enough to make pressure upon the vena cava and thus interfere with the return circulation. Movements. — The upper portion of the abdomen takes part in the movements of normal respiration, especially in males. Movement is restricted in peritonitis, in general enlargement, and when tumors occupy the upper portion of the abdomen. When tumors are in contact with the aorta, pulsation may be communicated to the morbid growth and 204 SURGICAL DIAGXOSIS AND TREATMENT. be perceptible through the abdominal walls. If the patient is placed* upon his hands and knees, the tumor falls awa)- from the aorta and pulsation ceases. Movements of the stomach may be observed in thin subjects, espe- cially when the viscus is much enlarged or displaced downward ; hence, dilatation may be diagnosticated by inspection alone. Sometimes peri- staltic waves of the stomach may be observed passing from left to right. If intense and persistent, this condition is spoken of as " peristaltic rest- lessness " of the stomach. Peristaltic movement of the intestines is a common symptom when there is narrowing or obstruction of the lumen of the bowel. In the case of the large intestine the wave may be traced along the course of the colon, but when the small intestine is involved the movx^mcnt is observed in the umbilical region. Palpation. — Of all the methods of examination of the abdomen, this is the most important, and can be brought to a high state of efficiency by cultivation. The abdominal walls must be well relaxed by raising the head and shoulders and by bending the knees. If the examining hand is cold, dip it in warm water, and two points will have been gained — the sense of touch will be more acute, and the abdominal mus- cles will not retract, as they are sure to do when they are touched by icy fingers. The recti muscles are especially prone to contract, and great care is necessary at times to distinguish this rigidity from a tumor. The point is readily settled by directing the patient to throw the rectus into action while the fingers are placed upon it. Most patients cause contraction of the recti by the simple movement of raising the head from the pillow. If this does not succeed, direct the patient to sit up, when the very first movement wall be contraction of the recti. Per- manent localized contraction of the muscles is indicative of inflamma- tion in the parts beneath. Palpation should be commenced by placing the palm of the hand over the umbilical region, and by a gentle motion (rolling the skin over the subjacent parts) pressing it steadily downward. If no tumors be felt, the hand without much difficulty can be made to feel the spinal column and the aorta down to its bifurcation. From this region the palm is rotated outward, and the ulnar side of the hand pressed gently but deeply into the lumbar and iliac regions. This will enable you to palpate the brim of the pelvis and the upper part of the common iliac vessels. Without relaxing the pressure the hand is made to roll the abdominal wall over the parts beneath, when any irregularities, if pres- ent, can be readily felt. One area after another is gone over in this manner, the hand still firmly applied, and sliding, when necessary, over the skin. If inspection has revealed a local enlargement, palpation will confirm it and give an idea of the shape, consistence, and character of the growth or other cause. When a tumor is found, we must settle the following points in connection with it : 1. In which region is it situated, and in connection with what organ ? 2. Is it circumscribed or diffuse ? This is determined by passing the fingers around it as far as possible, and between it and the abdominal bony boundaries. 3. Is it solid or liquid ? In tumors of dense structure, such as car- INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 205 cinoma, a feeling of hardness can be recognized, fluid tumors can be detected by their fluctuation, but between these two extremes are many- grades of consistency which are very difficult to determine. 4. Is it movable or fixed ? The hand should be placed upon dif- ferent parts of the tumor, or the whole tumor grasped by the hand and its mobility tested. If freely movable, note the effect of change of posture. It often happens that the patient can bring the growth into prominence by lying in one particular position. 5. Is its surface smooth or irregular, and is its consistence uniform? The points of the fingers moving the abdominal wall over the tumor will detect a nodular surface if it be present, as well as any irregularity of consistence, such as would result from the formation of cysts or abscesses in solid growths. Palpation bv the vagina is a means of diagnosis which is of wide utility. By means of it tumors in the pelvis can be felt between the finger of one hand in the vagina and the other hand on the abdominal wall. The connection of the tumor with the uterus, ovaries, tubes, or broad ligament can be settled and its pedicle or base localized. Palpation by the rectum is valuable in the diagnosis of tumors low down in the pelvis or involving the rectum itself It was recommended a few years ago as an aid to the diagnosis of appendicitis, but I am not aware that it has ever been extensively employed. In cases of great uncertainty, as in supposed stricture of the rectum high up, it may be necessary to introduce the whole hand. The procedure is difficult and not free from danger. I have had recourse to it but once, and have never met with any one who advocated it as a valuable method of diagnosis. Percussion. — This is not so important as palpation, of which it may be regarded as a variety. The practised diagnostication will bring out distinct sounds where the tyro finds only indefinite thuds. To percuss to the best advantage we should imitate the action of the piano. A little hammer strikes the wires with a sharp, quick stroke and rapidly rebounds, leaving the string to give out by its vibration a full, clear sound. The finger of the left hand represents the piano-wire, the mid- dle finger of the right hand represents the hammer ; the motion should be at the wrist, and the percussing finger should be brought dow^n with a sharp, quick tap, and made to fly back as quickly as possible, leaving the vibration of the part percussed to give out a clear, unrestricted sound. Applications of percussion will be considered under the special organs. Auscultation. — This method is valuable in the diagnosis of aneur- ysms, the demonstration of placental and uterine bruits, the friction- sound of peritonitis, and the pulsation of the fetal heart. The phonendoscope is an instrument of considerable value in exam- ination of the abdomen and thorax. It was invented by Bianchi of Florence, aided by Bazzi, the celebrated Italian physician. It is a modification of the stethoscope, the sound being amplified by means of a resonator similar to the receiver of a telephone. Its utility as claimed by the inventor lies in the following directions: i. It enables us to appreciate normal and pathological sounds in the various organs of the body — sounds that are not audible by any other means of aus- 206 SURGICAL DIAGNOSIS AND TREATMENT. cultation ; 2. By it may be determined the position, thickness, and relations of separate organs. It is thus employed : The instrument is placed upon the skin over the organ to be examined ; the index finger of the right hand gently strokes the skin near the instru- ment, producing a distinct vibratory sound which varies according to the size, density, and thickness of the organ under examination. The stroking is continued fartiier and farther from the instrument until a change in the sound indicates that the examining finger has passed from the organ under examination to one of different conducting power. The points at which this change takes place can be marked upon the skin and the limits of the organ accurately defined. In examining the liver the instrument should be successively placed in the following positions : beneath the ensiform cartilage ; in the right mammillary line in the seventh intercostal space ; in the ninth inter- costal space over the mid-axillary line. Yo\ the stomach, place the instrument in the following positions : the seventh intercostal space in the left mid-clavicular line ; on the linea alba near the left free edge of the ribs and below the greater curvature. In this examination the cardia, the pylorus, the coils of the intestine, and the nature of their contents, whether fluid or gaseous, can be determined. In examining the colon, place the instrument in the right iliac fossa for the cecum, and beneath the free border of the ribs in the anterior axillary and mid-axillary lines for the ascending colon ; for the trans- verse colon, on a line running from right to left a little above the umbilicus. The descending colon is examined by placing the instru- ment beneath the left free border of the ribs and also in the left iliac fossa. In all cases heavy strokes are necessary to detect fluids, and light strokes to detect gases. When a tumor is to be examined, the instrument should be placed over the center of the growth. Exploratory Puncture and Incision. — As a general rule, the exploring needle is dangerous in the abdominal cavity, and at this day is seldom or never resorted to by the best surgeons. When every other method of diagnosis has been carefully and exhaustively tried, and there is still doubt as to the question whether a given growth can be safely removed, it is proper to make an abdominal section. In the hands of a skilful operator a simple incision, to admit one or two fingers and explore gently the abdominal contents, is practically devoid of danger, and in a sense safer than the puncture of an exploring needle. On the other hand, there is nothing so mischievous as the idea that it should be resorted to in every case which offers obscure symptoms. The case may be obscure for want of skill and experience in the examiner ; to subject a patient to an operation as an outlet for ignorance is cruel and unwarrantable. When such an incision is decided upon, every preparation should be made for any radical operation which may be called for. The incision should at first be made only sufificient to admit one or two fingers. Through this opening a search can be made of the whole peritoneal cavity, after which the incision can be extended by scissors upward or downward as required. Unless it is reasonably certain that the radical INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 20J operation can be successfully carried out, the parts should be disturbed as little as possible and the opening closed. Injuries of the Abdomen. Contusions. — Owing to the looseness and mobility of the abdo- men, bruises and blows may produce the most serious results without any visible marks upon the skin. Shock is always pronounced, and death has often occurred with no other symptom, post-mortem ex- amination failing to reveal any structural lesion. Contusion of the abdominal wall may cause laceration of vessels and the formation of a hematoma in the sheath of the muscles or the areolar tissue. Hema- tomata are found most frequently in the flanks and may attain an enor- mous size. If they remain aseptic, absorption rapidly takes place, and no treatment except rest is necessary. Should they continue to enlarge by persistence of the bleeding, they should be incised, the bleeding ves- sel ligated, or the cavity packed with gauze. When sepsis sets in incis- ion and drainage are demanded. A blow while the muscles are in a state of rigid contraction may cause their rupture, leaving a weak spot which may later be the seat of a ventral hernia. Rupture of muscle may also occur during severe labor or in the violent contractions of tetanus. Debilitating diseases, such as typhoid fever, weaken the mus- cles and predispose them to rupture. The symptoms of ruptured mus- cle are pain and tenderness. When the rupture is extensive a depres- sion is found between the ruptured muscular structures. The treat- ment is rest and soothing applications. It may be practicable in some cases to cut down upon the injured part and suture the divided portions of muscle. It sometimes happens that septic germs find an entrance to bruised and lacerated tissues, and an abscess in the abdominal wall is the result. Such an abscess is surrounded by widespread indura- tion, and its contents, when evacuated, are often foul-smelling like those of an abscess near intestine. The parietal peritoneum is occa- sionally ruptured, and the result may be peritonitis. Injury to the Viscera from Abdominal Contusions. — The diagnosis of these internal injuries is always attended with difficulty. Shock is the most prominent symptom. The patient lies in a state of collapse. If this increases, we may assume that some organ has been ruptured or that hemorrhage is taking place. Hemorrhage is manifested by increasing pallor, paleness of the gums and lips, yawning, sighing, dilatation of the pupils, and by dulness on percussion when enough blood has been poured out to fill a part of the abdominal cavity. When an organ is ruptured we must wait for secondary effects. The bladder is the organ most easily examined. A soft catheter can be introduced. If clear urine escapes and in considerable quantity, we may know that there is no rupture ; if, on the other hand, a small amount of urine comes away and it is stained with blood, it is significant of rupture. It is seldom that an empty bladder is ruptured, except in cases where there is also fracture of the pelvis. The Stomach. — Rupture of this organ may be suspected when there is blood-stained vomiting. This, however, is not a sign of great value, for it may be due to bruising of mucous membranes, and, besides, 208 SIKGICAL D/AGA'OSIS AND TREATMENT. if the laceration in the stomach be extensive, there will be no vomiting, for the contents will escape into the peritoneal cavity. Pain in the epi- j^astrium is significant of rupture of the stomach ; pain antl tenderness around or below the umbilicus point to the intestine as the seat of rup- ture. Escape of gases into the abdomen and inflation sufficient to give resonance over the normal position of the liver are also very suggestive. A distended stomach is more liable to suffer rupture than one compar- atively empty, and the part of the organ generally torn is that near the pylorus. When the posterior wall of the stomach is ruptured the con- tents are confined by the lesser omentum and an abscess may result. The intestine is most easily ruptured at the point which is most fixed — viz. the end of the duodenum. The .symptoms will be con- sidered under Wounds of the Abdomen. The liver, owing to its size and weight, is liable to rupture. The symptoms are those produced by hemorrhage. Fracture of ribs over the liver, followed by collapse and other signs of hemorrhage, would be very strong presumptive evidence of rupture. Treatment. — Except when the shock is slight and a positive diag- nosis can be made, treatment must be expectant. Perfect rest must be enjoined, nourishment must be given by small enemata, thirst quenched by small pieces of ice, and stimulants avoided or very sparingly em- ployed. Pain may be removed by hypodermics of morphin. The prog- nosis is much more grave when internal organs are ruptured. These are usually desperate cases. The patient tosses from side to side, finding no easy posture until death relieves him, or the collapse deepens till the end arrives. Rupture of the bladder calls for immediate ope- ration, as does also any form of internal hemorrhage, provided the state of the patient warrants such interference. Wounds of the Abdomen. Wounds of the abdomen very naturally divide themselv^es into two classes: (i) Non-penetrating wounds; (2) Penetrating wounds. The most common causes of abdominal wounds are stabs and gun- shot injuries. A free incised wound can be readily examined and its depth ascertained. After washing out the clots the edges can be held apart and the divided tissues seen or felt. When, however, the wound is a small penetrating one, as a stab made by a knife-thrust or a bullet, the question of penetration is not so easily settled. Here the greatest care must be observed lest septic matter be carried into the peritoneal cavity. The skin around the wound and the wound itself should be carefully cleansed and disinfected. A director should then be passed into the wound and the opening enlarged by careful dissection down to the end of the director. Then another careful search should be made, and if the director can be made to pass farther, the dissection should be continued until it is clearly demonstrated whether the wound ends in the abdominal wall or enters the peritoneum. A non-pcnetratiiig zuound is not a serious matter. The parts having first been carefully disinfected, sutures of silk or silkworm gut are used to obtain perfect apposition of the parts, as in celiotomy, and a dress- ing applied. The danger of such wounds lies in the fact that the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 2O9 abdominal wall is weakened at that spot, and hernia is likely to follow. The patient should lie in bed for at least three weeks to give the parts time to become firmly united. He should afterward wear an abdominal belt or supporter, and should avoid severe muscular effort for many months. Penetrating zvounds are further divided into two classes : {a) those without visceral complications ; {b) those in which one or more of the viscera are perforated. When the external wOund is large, the peri- toneum divided, and the intestine or stomach protruding, the case is self-evident ; and all that remains to be done is carefully to wash the protruding viscera with sterilized water, return them to the abdominal cavity, and close the wound. The escape of omentum is also proof of penetration. In cases of stab or bullet wounds with small tortuous tracks it is usually necessary to explore, by dissection, in the manner already described. Penetrating wounds without visceral lesions often do well when treated antiseptically. The peritoneum should be sutured by itself by means of catgut, and a row of silkworm-gut stitches can be used to close the remaining structures. Symptoms of Visceral "Wounds. — In the examination of a stab or gunshot wound of the abdomen the course of the missile should be carefully noted. A bullet is not often deflected here, as in the case of the skull, and a line between the points of entrance and exit will in most cases indicate the region transv^ersed and the organs perforated. It may be set down as a rule that a bullet passing through the abdomen from side to side perforates the intestine in from four to fourteen places. A bullet passing antero-posteriorly about the level of the umbilicus gives a probability of no visceral perforation. The diffi- culty of diagnosis will be seen as we take up the symptoms one by one. Shock. — A non-penetrating wound of the abdominal wall may be attended with profound shock. A penetrating wound which divides the intestine in several places has been known to be so free from shock that the patient has walked several blocks or even one or two miles. Vomiting may be a marked symptom in non-penetrating wounds, so that it is no proof of visceral wound. The same may be said of pain and pallor of the skin. Hemorrhage. — The blood that gushes from the parietal wound counts for little, as it is the flow from some muscular vessels in the wall. Blood from a wounded internal organ is poured out into the peritoneal cavity, and produces constitutional effects which are difficult to distinguish from shock. We must be guided by the ordinary symptoms of hemorrhage, such as pallor of the face, lips, gums, and conjunctiva, yawning, sighing, fainting, thirst, and jactitation. Besides these, a careful examination should be made by percussion. Blood collecting in the abdominal cavdty soon gives dulness in the flanks, which changes with position, as happens in ascites. Escape of stomach or intestinal contents through the external wound is convincing evidence, but this happens only when the opening in the viscus is opposite to that in the parietes and is not tortuous. When the contents of these organs escape, they do so into the abdom- inal cavity, and give no evidence until peritonitis has set in. Emphysema signifies very little^ for it may be produced by air, u 2 10 SURGICAL DIAGNOSIS AND TREATMENT. which has entered the wound from without, jTist as Hkely as by gas which has escaped from the alimentary tract. Hydrogen-test. — To Senn we are indebted for a very valuable aid in the diai,niosis of wounds of the stomach and intestines. Hydrogen is a liarmless gas which can be injected into the alimentary canal in any quantit)% producing no other effects than distention and disinfection. The gas is prepared in the usual way from pure sulphuric acid, zinc, and water, and collected in a rubber receiver which holds not less than three or four gallons. The tube from the receiver is inserted into the rectum, and, while an assistant holds it in position and presses the anus about it to prevent escape, the gas is slowly forced into the bowel. If the ear or stethoscope be placed over the position of the ilio-cecal valve, a gurgling sound will indicate the passage of the gas into the small intestine. Should there be a perforation of the intestine, the gas escapes into the peritoneal cavity, and thence through the external wound, where it can be detected by a hissing sound or may even be ignited w^ith a match ; or, if it should fail to escape by the external wound, it will fill the abdominal cavity, getting between the liver and the parietes, and giving a resonant note in the normal position of hepatic dulness. When this test is to be applied to the stomach, a soft stomach-tube is employed and the gas injected as before. The hydrogen-test may also be found valuable in deciding the question of penetration. The gas is injected into the wound of entrance. If there is no penetration of the peritoneum, the hydrogen will pass along the bullet-track and escape by the wound of exit. Compress the wound of exit and increase the gas-pressure, and emphysema will be felt along the course of the bullet. If there is penetration, the whole abdomen will quickly become dis- tended and tympanitic. Objections to the use of hydrogen are the dangers of over-dis- tention, the difficulty of returning the bowel to the abdominal cavity, and the fact that it frequently fails as a test. Prognosis. — Wounds of the abdomen must always be looked upon as of the utmost seriousness. In considering the probability of recov- ery it is safe to estimate the three divisions as follows : 1. Non-penetrating wounds, prognosis favorable. Careful anti- septic treatment will result in prompt healing. Accurate apposition by sutures and prolonged rest in bed will guard against ventral hernia. 2. Penetrating wounds without visceral injuiy, while more dan- gerous than the preceding, are not necessarily fatal, a large portion recovering without intra-abdominal treatment, provided nothing of a septic nature has entered the abdominal cavity. 3. Penetrating wounds with visceral injury. These are almost surely fatal, death resulting from hemorrhage or peritonitis. When a large vessel is wounded or when there is profuse parenchymatous hemorrhage, as from the liver or spleen, death follows quickly. A wound of the stomach or intestine allows the escape of the contents of the injured organ into the peritoneal cavity. Peritonitis speedily fol- lows, and death takes place within forty-eight hours, more from shock, perhaps, than from sepsis. There is a bare possibility that recovery may follow even so desperate an injury as this. The stomach or intes- tine, being empty at the time of the accident, may at its injured point INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 211 form an adhesion with a neighboring serous surface, and the general peritoneal cavity be thus protected. This contingency, however, is too remote to enter into our calculations in making a prognosis. In this third class of cases nothing but prompt operative interference with the view of arresting hemorrhage or closing wounds in the viscera will change the prognosis. The mortality after these operations may be set down at about 62 per cent. Treatment. — A non-penetrating wound must not be treated with indifference. The shock is often severe, and frequently it is so more from fricfht than from the extent of the traumatism. Soldiers have been picked up on the battle-field in a state of profound shock, and have quickly rallied and gone on fighting when assured by the surgeon that the supposed fatal injury was only an abrasion of the skin. The treatment of a non-penetrating wound consists in disinfecting the wound and surrounding parts. None but perfectly aseptic fingers and instru- ments should be used in exploring the wound. Care must be taken in application of sutures to restore the abdominal wall to its original strength and thus prevent ventral hernia. When drainage is called for, a few strands of catgut are better than non-absorbent drainage- tubes. In penetrating wounds, when the omentum or viscera protrude, these structures must be examined for injury. They should then be carefully washed with sterilized water and returned to their normal position. The peritoneum should be closed by a continuous catgut suture and the abdominal wall by silkworm gut or strong silk. When the wound is of considerable size, the greatest care should be taken to guard against a subsequent hernia ; this is best averted by keeping the patient in bed for three or four weeks, and by having him wear an abdominal belt or support for several months afterward. Penetrating wounds with visceral injury either forbid interference or demand the promptest action. If the patient is evidently sinking, and his general condition such that he cannot endui-e a prolonged operation, he would better be left alone. Two conditions demand operation : (i) Profuse internal hemorrhage ; (2) Perforation of stomach or intestine large enough to allow the escape of its contents. No rules can be laid down as a guide in such cases ; the condition of the patient and the special indications must be left to the surgeon's individual judgment. When there is profound shock it is necessary to employ suitable remedies and wait for reaction. Symptoms of peri- tonitis should not be waited for. When they appear the case is almost beyond hope. Adhesions by this time will have taken place and per- forations cannot be found. The perplexing point to the surgeon is this : There is evidently perforation, but the patient's condition does not appear serious enough to demand operation. On the other hand, if he waits for these serious symptoms to come on, the case will then be beyond hope. It is unquestionable that the earlier an operation can be resorted to the better will be the result. Coley has shown that of 39 cases operated upon within twelve hours, 18 recovered. Of 22 ope- rated upon after twelve hours, only 5 recovered. Operation. — Iiistnniioits Required. — Besides the ordinar}^ instru- 212 SURGICAL DIAGNOSIS AND TREATMENT. mcnts required for an abdominal section, there should be at hand the follo\vin<^ : Four intestinal clamps ; ten round milliner's needles for enteror- rhaphy threaded with fine silk ; stout catgut for suturing wounds in the solid viscera. Preparation of tJic Paticiit. — For the relief of shock and for pro- longing anesthesia a hypodermic injection of ] grain of morphin and Toif ^'"'^iii of atropia should be given. If there is indication that the stomach is the seat of injury, this organ should be emptied by the stomach-tube and washed out with w'arm sterilized water. The bowels can be emptied by an enema containing a little salt. Some advocate the use of whiskey as a stimulating enema. The whole abdomen should be thoroughly washed and disinfected and the wound carefully cleansed. The Ineision. — Except when the position of the external wound would strongly indicate to the contrary, a median incision is to be chosen. It gives better opportunities for examining intestines and stomach and a broader field in which to search for bleeding vessels. No rule, however, can hold good here. The course of a bullet or the direction of a stab wound will afford a pretty safe indication of the organs injured, and these must be reached by the incision which best exposes them. Arrest of Hcniorrliage. — When hemorrhage is the prominent symp- tom, a free incision is necessary to bring the bleeding points into view. If one of the solid organs be wounded, the character of the bleeding will be parenchymatous. A wound in the liver should be treated with a suture of stout catgut or packed with a strip of iodoform gauze, the end of which is left projecting from the parietal wound. A profusely bleeding kidney may require nephrectomy ; a wounded spleen may bleed so profusely that nothing but splenectomy will suffice. When there is a copious flow of blood, which accumulates as fast as it can be sponged out, the aorta should be compressed by an assistant. This requires a larger incision than ordinary, to allow the hand of the assist- ant to reach the vessel just below the diaphragm. Compression of the aorta in this manner controls the flow of blood from all the abdominal organs, and gives the operator time to find the bleeding points. The vessels of the mesentery are best controlled by ligature en masse. Perforations. — Having checked all hemorrhage, a rapid search must be made for perforation of the stomach or intestines. As soon as an opening is found it should be immediately closed with pressure-forceps, and held in the angle of the wound by an assistant while the operator continues his search. Every opening, as soon as discovered, is clamped in a similar manner until all are secured. Greig Smith advises the use of abdominal irrigation during the whole of the time that closure of visceral wounds is being carried out. It cleanses the abdomen and thus saves time, and if water at a temperature of i io° F. be employed, it W'ill prove an excellent remedy for shock. Suturing the Perforations. — One by one the wounds are closed. Sponges are arranged around the abdominal opening and the intestine or stomach brought out. Lembert sutures are the most suitable. The INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 21 3 lacerated edges of the intestinal wounds are turned inward and the serous surfaces brought together. Four to six sutures should be applied to every inch of incision, and the best material for this purpose Fig. icx>. — Czemy-Lembert suture. Fig. ioi. — Jobert's suture tor partial division of gut : a, serous ; b, muscular ; c, mucous coat. is fine silk. Wounds in the intestine should be sutured transversely to prevent constriction of the lumen ; in the stomach the direction should be in the long axis of the organ. When the bowel is wounded near Fig. I02. — Lembert continuous stitch. its mesenteric border gangrene is apt to result, as there is a danger of the blood-supply being cut off from that part of the intestine. This may necessitate the removal of a portion of the bowel. A section of the b-=^. Fig. 103. — Jobert's suture for complete trans- verse division of gut : a, serous ; b, muscular ; c, mucous coat. Fig. 104. — The suture tightened, showing Lembert's suture introduced to give additional security. bowel will also require removal when there is a double perforation or a laceration so large as to destroy a great part of the circumference of the tube. When this has to be done the mesentery attached to the condemned part of intestine is tied off in sections with fine silk before 214 SURGICAL DIAGNOSIS AND TREATMENT. removal of the bowel. When the intestine is simply contused, the injured portion may be turned inward and sound serous surfaces brou^^ht together with Lembert sutures; then, should sloughing take place, the necrotic portion will fall within the bowel. Each wound after having been sutured is carefully washed, and, if possible, rendered more secure by an omental graft. This is accomplished by taking an adjacent portion of the omentum and laying it upon the contused or sutured surface of bowel, retaining it in position by two catgut sutures loosely tied. Adhesions will be hastened if the opposing surfaces are first scratched by the point of a needle. Irrigation of the Abdominal Cavity. — Having closed every perfora- tion and stopped all bleeding points, the cavity of the abdomen is next thoroughly washed out with warm water. If this has been kept up during the preceding steps of the operation, very little time will be required for a final flushing. In any case a full stream of warm steril- ized water or mild antiseptic solution is allowed to flow into the cavity, while the bowels are moved gently about to allow the fluid to reach every part, and this is kept up until the water returns as clear as it went in. The cavity is then dried with warm sponges. Drainage is necessary, as a rule, when there has been gross infection by the extravasation of visceral contents or when there is a continu- ance of parenchymatous hemorrhage. The parietal wound is closed by means of silkworm-gut sutures, as in any abdominal section. After-treatment. — When the intestine has been the seat of operation perfect rest of the organs, even from their own peristaltic action, is necessary. The stomach and upper part of the small intestine are rested by taking no food into the mouth for three or four days, and then only liquids, such as peptonized milk, diluted peptons, or jellies. Opiates are recommended for the purpose of restraining peristalsis. It is doubtful whether this is a wise procedure. If the dose of morphin and atropia be given just before the operation, as already advised, its effect will be to keep the intestines quiet for some time. Adhesions of serous surfaces take place rapidly, and, if union is to occur at all, it will be pretty firm at the end of twenty-four hours or even in less time. The arrest of peristalsis is not necessary beyond this, and opiates are certainly contraindicated as interfering with the absorbent action of the peritoneum. When a drainage-tube is employed care must be taken to keep the fluid drawn out at frequent intervals by means of an exhaust- ing syringe. Should the temperature rise and other symptoms of sepsis set in, it is probably because the peritoneal cavity is shut off around the drainage-tube and a collection of pus is taking place. The best thing to do in this case is to remove the drainage-tube, insert one finger into the opening, carefully break up the newly-formed adhesions, and wash out the collection of pus by irrigation. I am confident of having saved at least two cases of general peritoneal sepsis in this way. 6 When all goes well, liquid food can be given by the stomach at about the end of the third day, and solid food in an easily digested form at about the end of a week. The parietal wound is treated as in other abdominal sections, care being taken to allow a good firm cicatrix to form before the patient is allowed to go about, and an abdominal INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 21 5 support should be worn for sev^eral months with the view of preventing ventral hernia. III. EXAMINATION OF THE STOMACH. Inspection. — Valuable data in the diagnosis of diseased conditions of the stomach can be obtained from the amount of distention of the organ. A flat, collapsed condition at the epigastrium is sometimes seen when there is obstruction at the cardiac orifice ; bulging and tume- faction occur when the pylorus is the seat of stricture. Tumors in the anterior wall or at either orifice may cause a bulging at the epigastrium. Peristaltic movements may be observed in certain cases. Normal waves begin at the cardiac end and extend to the pylorus. Anti- peristaltic waves take the opposite course, and are an indication of stricture at the pylorus. These movements are increased by the use of the faradic current, or by the application of the ether spray, or by striking the abdomen with a wet towel. Palpation. — The first thing to be sought for is localized pain, which can be readily detected by making gentle pressure with the fingers over the region. Any inequalities in the abdominal wall should be carefully noted and a tumor sought for. Sometimes a growth is lower down than the normal position of the stomach, its own weight causing it to sink to a lower level in the abdominal cavity. Dilatation of the stomach may force a pyloric tumor downward. In its early stages a tumor of the pylorus is freely movable, later it becomes fixed. Percussion. — The whole of the stomach cannot be outlined by percussion. On the right side the liver overlaps a portion of the organ, while the lung encroaches upon it on the left. The lower limit is about midway between the ensiform cartilage and the umbilicus, and passes in a curve to the lower border of the end of the tenth rib. In percussing the stomach it is convenient to begin with the right hypo- chondriac region. From liver dulness we come abruptly upon the tympanitic stomach, and find no difficulty in determining where one begins and the other ends. On the left side the pulmonary resonance is easily distinguished from the tympanitic note over the stomach. At the lower border considerable difficulty may be met with. The stomach here is bounded by the colon, and it may happen that the note in both has the same pitch. As a rule, however, the note over the stomach is more tympanitic, louder in tone, and lower in pitch than that over' the colon, so that in the majority of cases the lower border of the stomach can be accurately mapped out. Allowances must always be made for the nature and amount of the stomach-contents. When the organ is full the note is dull and muffled, and the area of dulness corresponds with the degree of gastric distention. Change of position will be found to change the percussion-note. Gas rises to the surface, giving a tympanitic resonance, while fluid gravitates to the most dependent parts and affords a dull note. As an aid in ascertaining its exact size, Piorry suggested filling the stomach with water. About a liter is given the patient to drink, and he is examined when standing. The stomach thus distended gives a dull note, in contrast to the tympanitic sound produced when the colon is percussed. 2l6 SUKU/CAI. D/AGiVOS/S AND TREATMENT. The metliod of Dchio consists in ^ivinj^ the water in fractional quantities. The hter of water is divided into four parts, each part being taken separately at short intervals, and an examination made after each dose. The area of dulness is marked upon the abdomen after each examination. This method is valuable in detecting dilatation of the stomach and atony of the organ. When the area of dulness descends below the umbilicus, it indicates dilatation. When the dull area descends rapidly after each addition of water, atony of the gastric muscle may be diagnosticated. The lower limit of a healthy stomach never descends below the umbilicus. Frielich was in the habit of distending the stomach with carbonic- acid gas. The patient took 2 grams of sodium bicarbonate dissolved in water, and then an equal quantity of water containing 2 grams of tartaric acid. A rapid disengagement of carbonic acid takes place in the stomach, which so distends it that the contour of the organ may be seen through the abdominal wall. This method is not free from danger, as the distention may be excessive and is always beyond con- trol. Sometimes the quantity of gas is not sufficient to distend the stomach. The method of Runeberg is the most satisfactory. It consists in distending the stomach with air by means of a tube to which is attached a rubber bulb. The quantity of air is thus under direct control, and the stomach is examined in different degrees of dis- tention. At the end of the examination the air can be withdrawn through the tube. All these examinations are greatly aided by the use of the phonendoscope. (See ^Examination of the Abdomen.) The stomach itself is movable, rising beneath the chest-wall when pushed upward by abdominal distention, and sinking lower into the peritoneal cavity when anything depresses the diaphragm. An enlarged liver encroaches upon the stomach from the right, and an enlarged spleen from the left. Contraction of the liver, on the other hand, increases the area of stomach-resonance. Auscultation is of little value in the diagnosis of stomach-diseases. Splashing, gurgling, and metallic sounds may be produced by rapid voluntary movements of the diaphragm, by the natural movements of the stomach itself, by moving the patient quickly from side to side, or by pressing upon the stomach and suddenly relaxing the pressure. If you direct the patient to swallow fluid and place your stethoscope over the esophagus, two sounds are heard : the first is a spurting sound, and is due to the passage of the liquid along the esophagus ; the second sound is produced by the escape of the fluid from the esophagus into the stomach. In healthy conditions the interval between these two sounds should not exceed ten seconds ; in cases of constriction of the cardiac orifice the interval may be extended to a minute or more. Chemical exaniiiiatioii of stoinach-conicnts (see Cancer of the Stomach). Injuries and Diseases of the Stomach. The chest-wall above and the thick muscular abdominal wall in front protect the stomach from external injury. A sharp instrument can readily pierce the organ, but a blow from a blunt object throws the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 21/ abdominal muscles into strong contraction, and the stomach readily yields before the pressure or slips from under the force. If, however, the stomach contain a considerable quantity of food or be distended with gas, rupture may take place. One or more coats may give way or the whole thickness of the gastric wall may be lacerated, permitting the contents to flow into the peritoneal cavity, and producing death by peritonitis within forty-eight hours. When one coat only is ruptured, it is usually the peritoneal, that being less elastic than either the muscular or mucous covering. Syniptoiiis of Rupture. — When only the peritoneal coat is ruptured, the symptoms are pain and localized peritonitis. The torn perito- neum almost immediately becomes adherent to the peritoneal sur- face of some other organ, adhesive inflammation throws out a bar- rier against further mischief, and the process of repair rapidly takes place. A localized peritonitis, following a blow or kick over the stomach, is very suggestive of this form of rupture, and such a condi- tion should be treated by placing the organ at perfect rest by with- holding food for several days and by nourishing the patient with nutrient enemata. When the mucous or muscular coat is ruptured hemorrhage into the stomach is the prominent symptom. Vomiting of blood must therefore be regarded as very important when it follows a traumatism in the epigastric region. Rupture of the whole thickness of the stomach- wall is followed by the most serious symptoms. Shock is severe and pain is intense. The contents of the stomach are poured out into the abdomi- nal cavity, and the symptoms of general peritonitis rapidly appear. Some patients never rally from the first shock ; others die of peri- tonitis in about two days. Tvcatinoit. — If ever there is a condition requiring prompt and immediate heroic measures, it is here. Once the diagnosis of complete rupture has been made, there is not a moment to be lost. A free incision, beginning at the ensiform cartilage and extending to the umbilicus, is required. The rent should then be sought and brought to the surface. If situated at the posterior wall of the stomach, the gastro-colic omentum must be divided before the laceration can be reached. Having brought the edges of the rent to the abdominal wound, the stomach should be washed out with sterilized water, after which it should be sutured by two rows of silk stitches, the one passing through the muscular and mucous coats and cut short. The second row takes the peritoneum and passes into the muscular coat, so that it buries the first row and brings the peritoneal surfaces together. Any stomach-contents found in the peritoneal cavity should be mopped out with sponges, and, if there be general contamination, the whole should be flushed with sterilized water or Thiersch's solution. Drainage is necessary when the contamination has been extensive or long con- tinued. The after-treatment requires stimulation by hypodermics of strychnia or brandy and perfect rest to the stomach. Foreign Bodies in the Stomach. — Children frequently swallow coins and other small bodies with impunity. I had until recently in my possession a pocket-knife blade, one and three-quarter inches in length, which passed through the alimentary canal of a four-year-old boy. 2l8 SURGICAL DIAGNOSIS AND TREATMENT. The blade was somewhat eroded, but the boy was none the worse for the mishap. Bodies which pass through the pharynx and esophagus are pretty sure to pass through the remainder of the digestive tract, particularly if the friends abstain from the common practice of giving purgatives. Food should be allowed which ensures the formation of bulky stools, and for this purpose an exclusive diet of mashed potatoes and milk answers admirably. Mechanical Fixation of the Stomach. — When from injury, disease, or as a sequel of celiotomy the stomach becomes adherent to the parietes, considerable suffering and inconvenience may result. Such cases are often set down as gastric neurosis. Landerer of Leipzig has reported three cases of intense gastralgia attended with vomiting and tenderness at the epigastrium. In the first case a band of adhesion was found between the parietal peritoneum and the stomach, the removal of which was followed by perfect recovery. In the second case the stomach was found adherent to the left lobe of the liver, and recovery followed the breaking up of the adhesion. The third was produced by a small umbilical hernia, to which a section of the stomach the size of a small apple was firmly adherent. All the symptoms subsided after freeing the stomach and stitching the her- nial ring.^ A case is reported by Dr. Davis of Omaha in which persistent attacks of vomiting, severe gastric pain, nervousness, cardiac depres- sion, and high temperature were finally traced to a small hernia in the linea alba, to the sac of which was attached a band of omentum. Tracing the omentum inward, it assumed the form of a band the end of which was adherent to the greater curvature of the stomach. Division of the band and radical treatment of the hernia effected a com- plete cure. Landerer points out a very simple and reasonable symptom of this condition. // is the production of pain in the stomach from movement of the visciis. Washing out the stomach and movements of the body which cause a dragging of the stomach at the adherent point are followed by long-continued pain. Ulcer. — Ulcer of the stomach until a recent date was regarded as entirely within the domain of medicine. At present it may be looked upon as an outpost on the frontier of surgery. Perforating ulcer has long been recognized. Its starting-point is in a small arterial branch which becomes occluded, and thus the supply of blood is cut off from a portion of the stomach-wall. Necrosis of the area thus cut off follows. The necrosed part takes the form of a cone with its apex toward the peritoneal and its base at the mucous coat. The destruction of tissue is hastened by the action of the gastric juice, and the slough, coming away en masse or by molecular death, leaves an ulcer which the term " perforating " aptly describes. Not infrequently severe hemorrhage follows, and by repeated losses of blood the patient may be brought to a state of great anemia and even unto death itself Symptoms. — Two leading symptoms attract our attention in gastric ulcer — a fixed pain with localized tenderness on pressure, and vomiting soon after taking food. Surgically, we are interested in ulcer from the ' Annual of Universal Medical Sciences, 1894. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM 2I9 fact that perforation is a not infrequent termination. Haslan of Bir- mingham, England, describes perforating ulcers under three classes : 1. Where no adhesions have formed around the base of the ulcef, and the stomach-contents pass at once and freely into the peritoneal cavity. The location of ulcers of this class is usually on the anterior surface of the stomach The symptoms here are sudden and severe, almost identical with those following rupture of the stomach. Shock is more or less marked ; there are abdominal pain and tenderness on pressure, with the train of symptoms which make up the sum-total of general peritonitis. The duration of life after perforation occurring in this manner ranges from seven hours to five days, the majority dying within twenty-four hours. 2. Where adhesions around the base of the ulcer have fixed the stomach to some adjacent organ, the leakage causing a localized peri- tonitis. Suppuration follows perforation of this class, but the collec- tions of pus are shut off from the general peritoneal cavity. The diag- nosis here must rest upon the history of gastric ulcer, the occurrence of localized peritonitis, followed by induration, and such other signs as indicate a collection of pus. 3. Cases in which adhesions have formed between the stomach and some hollow viscus or serous cavity, into which an opening from the stomach becomes established. In this way the stomach-contents have found their way into the colon, the pericardium, or the pleura. Treatment. — In the first class of cases clinical experience teaches us that there is only one termination — death — and that the fatal issue occurs in the majority of cases within twenty-four hours. Any attempt, therefore, which gives a hope of placing the patient in a more favorable position is justifiable. The operation recommended consists in making an incision above the umbilicus a little to the left of the middle line, in order to avoid the falciform ligament. The patient, being the subject of shock, must be treated for this condition by hypodermics of str}xhnin and by surrounding him with hot bottles. The most common seat of ulcer is found to be at or near the lesser curvature. As a rule, the portion of the stomach which presents at the parietal wound in this operation is the greater curvature or the part a little above it. The finger should be made to pass over the surface of the stomach upward and backward in search of the perforation, and, as already stated, it will be found at or near the lesser curvature. The succeeding steps of the operation are identical with those in the operation for rupture of the stomach. Gastric Fistula. — In the rare cases in which adhesions form between the stomach and the abdominal wall and shut off the peri- toneal cavity before the occurrence of perforation a gastric fistula may be the result. A similar condition may arise after a wound of the abdominal wall which extends into the stomach, or the fistula may be intentionally made for the relief of a constriction at the lower end of the esophagus or at one or other of the orifices of the stomach. Treatment. — The operation for the closure of the gastric fistula will vary according to the length and connections of the fistulous tract. If the fistula is short and the stomach in close connection with the abdom- inal wall, the closure can be effected without opening the peritoneal 220 SURGICAL DIAGNOSIS AXI) IREATiMKNT. cax'ity. An incision about two inches in length down to, but not through, the peritoneum exposes the opening in the stomach. The edges of the whole fistulous tract should next be thoroughly freshened by paring them with a sharp knife or scissors. Four rows of sutures are then applied, as follows : 1. Fine silk pa.ssing through the mucous and submucous coats. 2. Catgut sutures to include the remainder of the stomach-wall. 3. A deep row of catgut to unite the deep layers of the abdominal wall. 4. A row of silkworm gut to unite the skin. Over this a copious aseptic dressing is applied and retained by long strips of adhesive jilaster. The stomach is kept at rest by giving all nutriment by the rectum for the first four or five days. When the fistulous tract is larger and the stomach is not in close connection with the abdominal wall, the peritoneal cavity must be entered. The stomach is completely separated wherever it is found to be adherent to the parietes, and the opening closed as in wounds of this viscus. Cancer of the Stomach. — " Obscure in its symptoms, frequent in its recurrence, fatal in its event." Such is the description of cancer of the stomach given by Brinton. Of the tumors found in connection with the stomach, carcinoma is by far the most common. Sarcoma is exceedingly rare. Benign tumors are seldom found in this locality, and, if they do exist, require no surgical treatment. Of all cases of cancer, 35 to 45 per cent, occur in the stomach, which is more liable to the disease than any other part of the alimentary canal except the tongue and lips. The maximum liability lies between the ages of fifty and sixty. It is rare before the thirtieth year, and congenitally it almost never occurs. True to the pathological law that carcinoma is most likely to occur where two kinds of epithelial cells meet, cancer of the stomach begins, as a rule, either at the cardiac or pyloric orifice. One-half of all cases, according to Bernays, begin at the pylorus. Of 903 cases analyzed by Gussenbauer and Winnewarter, 542 were pyloric. The pylorus is per- haps more susceptible, owing to repeated slight injury due to the passage through it of hard or indigestible masses of food. It is quite a common thing to find post-mortem old cicatrices in the mucous membrane of this locality, which, combined with the clinical fact that cancer has a tendency to occur in scar-tissue, gives some show of reason to the theory. Next in frequency of situation is cancer of the greater curvature. In other positions the disease is extremely rare. Once the neoplasm has started, it tends to grow toward the lumen of the stomach. The mucous membrane is the structure first affected ; next the submucous loose connective tissue ; and only in the last stage are the muscular and serous coats invaded. Early and accurate diagnosis is of the utmost importance, and I would submit the following points as a practical mode of procedure in any case of suspected gastric cancer : I. History. — If a patient more than forty years of age gives a history of disturbed digestion dating back for several months or a year, combined with cardiac or pyloric stenosis, the suspicion of cancer INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 221 of the stomach must be entertained. Pain, as a rule, is not felt until an advanced stage of the disease. Vomiting occurs without much effort and with little nausea. At first the vomit consists chiefly of mucus, remnants of food, and watery fluid mixed with bile, but by degrees the stomach-contents are expelled in a more and more undi- gested state. It is not until ulceration has become established that blood is vomited. The blood may be in small amounts as bright-red streaks in the mucus, or the quantity may be large and changed in appearance according to the length of time it has remained in the stomach and the changes it has there undergone. Then it may be in bright-red or brownish-red clots or coagula, vaiying in shade from brown chocolate color to black. This, the so-called " coffee-grounds " vomit, was formerly supposed to be pathognomonic of cancer of the stomach, but experience has proved this to be an unreliable sign, for other diseases are attended with " coffee-grounds " vomit. At the same time it must be borne in mind that, as a rule, the blood remains longer in the stomach in cancer than in other diseases, and " coffee-grounds " vomit has therefore considerable significance, con- sidered with loss of strength and progressive emaciation. The fat and muscles rapidly waste away, and ere long the patient becomes decidedly emaciated. 2. Physical Examination. — In all cases of abdominal examination it is convenient to map out by means of a colored pencil the abdominal areas — viz. epigastric, right and left hypochondriac, etc. Besides these I would draw a line from the points of the false ribs on either side to the umbilicus. On the right side this line with the linea alba and line of the false ribs forms a triangle in which tumors of the pylorus are to be sought for. On the left side the line marks the boundary of normal stomach-dilatability. If the stomach falls below this line, we may say that there is abnormal dilatation. For a thorough examination the patient should be anesthetized. 3. Inspection. — Standing at the patient's feet and looking down upon him, we can observe an)' irregularity in the abdominal wall. A growth in the stomach may be visible as an elevation over the situation of the organ. A depression in the epigastrium points to obstruction in the esophagus, a fulness in the epigastrium to pyloric stenosis. 4. Palpation and Percussion. — We may expect to find a tumor in three-fourths of the cases. A tumor at the cardiac orifice is hard to find by palpation, owing to its distance from the surface. It is only when it has attained considerable size that its presence is clearly demon- strated. At the pyloric end, however, the tumor is more easily felt, and its common position is between the ensiform cartilage and the umbilicus, a little to the right of the middle line. Having found the growth, we may ask ourselves the following questions : First. Is the tumor movable ? Its weight may drag it downward, so that it falls below the line we have marked upon the skin from the border of the false ribs to the umbilicus. If freely movable, it is an indication that there is no invasion of neighboring organs. Still, this rule cannot be insisted upon, for in one recorded case the tumor was freely movable, and yet the adhesions were so strong and so numerous that the operation had to be abandoned. On the other hand, fixation 222 SC'KGICAL D/AGXOS/S AND TREATMENT. docs not certainly indicate extension of the disease to neit^hboring structures. W'lien it has become adherent to the hver and diaphragm, it rises and falls with respiration. Dilatation of the stomach may cause mobility of the tumor. If the stomach be greatly dilated and the pylorus fixed in an abnormal situation, it strongly suggests extension of the disease. If irregularity of the surface of the growth coexists with these conditions, we may certainly infer that the disease has spread, and then operation is out of the question (Greig Smith). Second. Is the stomach dilated ? This can be ascertained by dis- tending the organ. Frerichs employed for this purpose carbonic-acid gas generated outside the body — for example, from an inv^erted siphon of mineral water. Safer and more satisfactory is the method of Rune- berg, which consists in introducing a stomach-tube and then insufflating air by the double bulbs of a spray apparatus. As a rule, we have other reasons for introducing the tube, so that the inflation of the stomach with air gives very little additional trouble. Besides percussion of the stomach, we may with advantage employ succussion in its two forms — viz. digital and total or Hippocratic. The writings of Bouchard have brought this matter of examination into considerable prominence. It is thus employed : The patient lies on his back with the abdominal muscles relaxed. The surgeon makes a series of rapid taps with the extremity of the fingers on the abdominal wall along the line running from the umbilicus to the edge of the false ribs on the left side. If a certain amount of liquid and gas is present, we obtain in this way a sensation of splashing to which Bouchard attaches great importance. The presence of a gastric succussion-sound when it is perceived below a line extending from the umbilicus to the border of the false ribs on the left side indicates a permanent dilatation of the stomach. It is import- ant only when obtained a long time after a meal, and especially when a patient is fasting in the morning (Mathieu). The significance of dilatation lies in the fact that it corroborates obstruction at the pylorus. Contraction, on the other hand, argues in favor of obstruction at the cardiac orifice. 5. Examination of the Contents of the Stojuach. — The surgeon is not justified in neglecting this means of diagnosis in any chronic gastric disease. As the procedure is not yet so generally employed as its importance demands, I may perhaps be pardoned if I very hurriedly run over the steps of most practical utility in aiding diag- nosis. It is important in the examination of the stomach-contents that a uniform method should be followed. Different results will be obtained at different periods of the digestive process. A scanty diet will not call forth the activity of the gastric glands to the same degree as a hearty meal. For conv^enience and uniformity, a so-called test breakfast is given on an empty stomach, and the contents are drawn off an hour to an hour and a half afterward. This breakfast consists of an ordinary dry roll without butter, and about two-thirds of a pint of wx^ak tea or coffee without milk or sugar. Such a repast contains albuminoids, sugar, starches, non-nitrogenous extractives and salts, thus offering the stomach all the ingredients that are usually taken, while at the same time liquefaction takes place INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 223 rapidly, and there are no solid pieces of food, such as meat, to plug the opening in the stomach-tube. The patient having taken the test breakfast at about 8.30 a. m., pre- sents himself at 9.30 or 10 for examination. To obtain the stomach- contents, the simplest plan is that known as Ewald's expression method. A soft-rubber stomach-tube is passed, and when the end has entered the stomach from twenty-three and a half to twenty-five and a half inches from the incisor teeth, the patient, by contraction of the abdomi- nal muscles, forces the stomach-contents through the tube into a receiving vessel. This fluid is then filtered, and, as a rule, presents the appearance of an amber-colored liquid resembling normal urine. Before proceeding further we must bear in mind that during digestion the stomach normally has acid contents. Ewald and Boas by numer- ous experiments found during the normal digestion of the test break- fast the following three stages : 1. As early as ten or fifteen minutes after a meal the stomach- contents often are acid. The acidity depends upon the free acids, acid salts, or both. The free acid is the lactic acid. Up to thirty or forty- five minutes the lactic acid predominates, while the color-tests for hydrochloric acid are negative. 2. Then comes a stage in which both hydrochloric and lactic acid can be found. 3. The lactic acid disappears, and only hydrochloric acid can be found after the first hour. The secretion of hydrochloric acid begins, however, immediately after the food is taken. A sample, therefore, drawn one hour and a half after the test break- fast should be acid, showing a total acidity of 40 to 65 per cent, as we shall afterward explain, and this acidity should be due to hydro- chloric acid in the proportion of 14 to 24 per cent. The questions we have to answer are as follow : 1. Are the stomach-contents acid ? Litmus-paper quickly settles this point. 2. How acid are the contents? or, in other words, what is their total acidity ? This is obtained by trituration of volumetric solutions and the burette. We need for this purpose a burette and two solutions. The first is a decinormal solution of caustic soda. The atomic weight of caustic soda (NaHO) is 40. Forty parts, then, of soda in one thousand parts by weight of distilled water is a normal solution (40 to I liter). A decinormal solution is one-tenth of this strength, or 4 grams to a liter. The other reagent is a solution of phenol-phthalein in alcohol. Phenol-phthalein is a buff-colored powder freely soluble in alcohol. It remains colorless in acid or neutral solutions, but assumes a carmine color in alkaline solutions. Fill Mohr's burette with the decinormal solution of caustic soda. Into a glass beaker pour 10 c.c. of filtered stomach-contents and add one or two drops of the phenol-phthalein solution. (It gives a milky character to most stomach-contents, but that does not interfere with the test.) Next add very gradually the solution in the burette. As the drops fall upon the fluid in the beaker a carmine color is produced which disappears on shaking. This will continue as long as the contents of the beaker are acid. When the carmine color no longer disappears 224 SURGICAL DIAGiVOSIS AND TREATMENT. on shaking, stop and read off the number of c.c. of dccinormal solution of caustic soda which have been employed. Suppose 9^- c.c. have been used to neutralize 10 c.c. of stomach-contents. Ten times that c[uantity, or 95 c.c, would be required to neutralize lOO c.c. It is convenient to express this as a percentage according to the amount of decinormal solution used. In this case 95 c.c. were required to neutralize 100 c.c. Hence we express it as 95 per cent, total acidity. The normal acidity after the test breakfast is 40 to 65 per cent. So that in the sample before us the total acidity is too great, being 30 per cent, above the normal limit. At this point I might state that if we knew that the total acidity is due to hydrochloric acid, we can readily calculate the amount of acid. Each c.c. of soda solution used represents .003646 of the hydrochloric acid. We have used 95 c.c, which, multiplied by .003646, equals .346370 per cent. The normal limit is y^jj to y^^'^fj- of i per cent. The next point is to determine whether the acidity is due to the presence of free acids or to acid salts. The readiest method is by the use of Congo-red paper. Dip a piece of Congo-paper into the fluid and slowly dry it. The bright red is changed to a sky-blue, showing the presence of a free acid. 3. What acids are present ? The most important are hydrochloric, lactic, butyric, and acetic. For the detection of hydrochloric acid the best test is Giinzberg's reagent. It surpasses the anilin dyes and all the other tests, being so delicate as to show hydrochloric acid when it is as low as i in 20,000. The reagent is made as follows : Phloroglucin, gr. 30; Vanillin, gr. 15 ; Absolute alcohol, 5J. Nothing can be more simple than the application of this test. Take a small porcelain dish and place upon it two or three drops of the gas- tric contents, and add an equal quantity of the reagent. Now gently heat the dish over a spirit lamp, and as the fluid evaporates around the edges will be seen a bright rosy-red color. Blowing upon it, and thus aiding evaporation, brings out the color more distinctly. This is proof positive of the presence of hydrochloric acid, and from the intensity of the color may be roughly estimated the amount of hydrochloric acid present. We know that the limit of reaction lies at i to 20,000. By successively diluting the stomach-contents one-third, one-fifth, one- tenth, till the reaction is no longer obtained, we can roughly estimate the amount of hydrochloric acid. The next acid to search for is lactic acid. Until recently it was believed that the presence of any of the organic acids was patho- logical, since it was proved that the only acid secreted by the gastric glands is hydrochloric acid. Ewald and Boas, however, found that lactic acid can generally be detected in the early stages of digestion in healthy stomachs, and that this condition is normal. If organic acids are found in the later stages in such quantities that they can be detected with the ordinary reagents, then they always have a pathological sig- INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 225 nificance. They are the results of fermentation of some of the sub- stances acted upon by the gastric juices, such as sugar and albumins. Lactic acid can exist under two conditions : (i) as the result of fermentation ; and (2) as it exists normally in meat in the form of sarcolactic acid. In chemical character these two forms do not differ from one another. The simplest test for lactic acid is the neutral ferric-chlorid solution. A diluted solution of this salt turns canary yellow in the presence of lactic acid. The only difficulty about this test is that we have to dis- tinguish between two shades of yellow. We are indebted to Uffelmann for an excellent improvement upon this method. He takes a few drops of a neutral ferric-chlorid solution and adds one or two drops of pure carbolic acid (or about 10 c.c. of a 2| per cent, solution of carboHc acid) ; he then adds water until the solution assumes a beautiful amethyst-blue color. If to this fluid be then added even a trace of lactic acid, the canary-yellow color is produced ; fatty acids produce an ashy-gray color ; if inorganic acids are present, the solution is decolor- ized. So delicate is the test that lactic acid can be detected in solutions containing i : 2000. « 4. What is the digestive power of the stomach ? The albuminates are changed in the healthy stomach into propeptones and peptones, which are thus examined : {a) Propeptones. To a small quantity of the filtrate add an equal part of a saturated solution of sodium chlorid. If propeptone is present, it is precipitated, and the more turbid the fluid becomes the greater is the quantity of propeptone. When no precipitate is formed, add a drop or two of acetic acid ; the precipitate quickly follows if propeptone is present. On heating, the precipitate is dissolved, but returns as soon as the fluid cools. {6) Peptone. After precipitating the propeptone and filtering, the filtrate is made strongly alkaline by the addition of a solution of sodium hydrate. A few drops of a i per cent, solution of sulphate of copper are then added. A violet-red or purplish color is produced if peptone is present [c) Pepsin. A disc i mm. in thickness and i cm. in diameter of the white of a hard-boiled q%^ is added to 5 c.c. of the filtrate in a test-tube and kept at the temperature of the blood. If pepsin is present, the &^^ disc is digested and disappears in from two to six hours. If the filtrate contains no hydrocHloric acid, a few drops of the dilute acid should be added. [d^ Rennet ferment. To 5 c.c. of milk in a test-tube add three or four drops of the filtrate. After thoroughly mixing place the tube in a glass of warm water. If rennet ferment be present, the milk will become curdled in from ten to fifteen minutes. Starchy foods are converted into dextrin, erythrodextrin, achroodex- trin, and maltose. The test for all of them is Lugol's solution (iodin 0.1, potassium iodid 0.2, distilled water 200). A few drops of the solution are added to a small quantity of the filtrate. The result is as follows : {a) Dextrin turns the fluid blue. if) Erythrodextrin turns it red. 226 SURGICAL DIAGNOSIS AND TREATMENT. ic) Achroodcxtrin discolors the solution. (r/) Maltose does not change the color of the solution. Wliat do we learn by this examination ? Simply this : If hydro- chloric acid be present in normal amount, it is strong evidence against cancer. If it be absent or greatly diminished, it is very strong cor- roborative evidence of the existence of a cancer. Much discussion has taken place on this question. When Vander Velden expressed the opinion that cancer of the pylorus accompanied by dilatation of the stomach leads to suppression of hydrochloric acid, the view was rapidly applied to all forms of cancer of the stomach indiscriminately. Later investigations showed that this statement could not be main- tained in its entirety, yet it has led to results of great diagnostic and therapeutic significance. When the new growth is confined to a small area, when the accompanying catarrh of the mucous membrane is moderate, and when there is no atrophy, then the secretion of hydro- chloric acid may remain ample. Clinically, however, one of these features is absent, and the secretion of hydrochloric acid is entirely annihilated or is reduced to the smallest quantity. It is true that other conditions of the stomach give rise to a diminution of the secretion. These conditions are atrophy and amyloid degeneration of the mem- brane, mucous catarrh, and certain neuroses, but, notwithstanding all this, the absence of hydrochloric acid seldom fails clinically to cor- roborate a diagnosis of cancer of the stomach. The significance of lactic acid has been recently receiving atten- tion. Boas uses as a test meal flour soup quite free from lactic acid, and states that this acid was never found in any conditions except those of carcinoma. His results have been confirmed by Dr. D. Stewart* Ischochymia, or the retention of chyme in the stomach, is a symp- tom of great value. In this condition the organ has not the power to empty itself, and contains food even while the patient is fasting. As a rule, it is associated Avith dilatation of the stomach, and the commonest cause of dilatation is stricture at the pylorus. But dilatation is not necessarily present, for it does not usually appear until the stricture at the pylorus has existed for some time. The value, then, of ischo- chymia as a symptom lies in the fact that it can be recognized at an earlier period in the disease than that at which dilatation can be detected. To recognize the condition it is necessary to examine the stomach- contents while the patient is fasting. Einhorn instructs his patient to have at his supper on the night preceding the examination soup, meat, bread, and some rice, as this latter is very easily recognized, and, as a rule, retained in the stomach when there is stricture of the pylorus. The stomach-tube is employed in the usual manner, and if no chyme can be withdrawn by expression, it is necessary to wash out the stomach. If ischochymia is present, the rice and particles of the other articles of diet are found in an undigested state. Microscopic examination may sometimes throw light on the case. In the vomited matter, in the gastric contents obtained after a test breakfast, in the washings after lavage, or in the tube after an explora- tory examination shreds or small particles of tissue may be found. 1 Medical Record, Mar. 9, 1S95, quoting from Medical News. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 22/ These should be examined under the microscope, and may decide the question of cancer. Examination of the urine may be employed for further testimony. The presence of indican, which is the form in which indol is eliminated from the urine, is perhaps suggestive of cancer, but as it may be found in almost any wasting disease, its diagnostic value is not worth men- tioning. Its qualitative determination is very easy. Take lo c.c. of hydrochloric acid and i c.c. of chloroform. To this add lo c.c. of urine, and by means of a glass rod add one or two drops of a con- centrated solution of chlorid of calcium. The mixture is next shaken, and, if indican be present, the chloroform assumes a blue color, due to the formation of indigo. Gastroscopy, or the examination of the gastric mucosa by electric illumination, is not only of little value, but dangerous. Gastro-diaphany, or transillumination of the stomach, has never come into general use. In spite of all the care that can be exercised, some cases of gastric carcinoma will prove puzzling, to say the least. The gastric crises of locomotor ataxy have been mistaken for the symptoms of pyloric cancer, and operated upon to find no evidence of malignant disease or pyloric obstruction. Gastric cancer has been mistaken for pernicious anemia, and transfusion of blood resorted to. Simple fibroid contrac- tion of the pylorus is often indistinguishable from scirrhus, except after microscopic examination. Moreover, cancer of the stomach may occur without any symptoms whatever, and be discovered after death from other causes. Such being the status of our methods of research, we have to resort to something more definite in search of evidence, and complete the examination in these doubtful cases by making an ex- ploratory incision. To quote the words of Loreta : " It may now be accepted as a maxim in surgery that an exploratory abdominal incision is to be recommended in cases of malignant disease of the stomach where a diagnosis cannot be arrived at by other means." Are there any conditions under which the diagnosis of cancer can be positively made without exploratory incision ? Einhorn gives the following as sufficient evidence to answer this question in the affirmative : If particles of tumor are found (in the wash-water or in the sound) which under the microscope reveal the characteristic picture of a malignant growth ; The presence of a more or less large tumor with an uneven surface, belonging to the stomach and associated with dyspeptic symptoms ; The presence of a tumor associated with frequent hematemesis ; Constant pains, frequent vomiting, ischochymia, emaciation, all these symptoms being quite permanent, and not extending over too long a period of time (six months to one year) ; Tumor and ischochymia ; Emaciation, ischochymia, presence of lactic acid. Constant anorexia and pain, not yielding to treatment, accompanied by frequent small hemorrhages (of coffee-ground color). Treatment. — The surgical treatment of carcinoma of the stomach may be curative or palliative in its aim. 228 SURGICAL DIAGNOSIS AND TREATMENT. The simplest and most readily ai)plicable remedy is lavage. Ewald calls it the sovereign remedy for dilatation. The ordinaiy stomach- tube with funnel attached is all the apparatus required. Warm water in large quantities should be alternately introduced and removed by siphonage until turbidity ceases and all shreds, fragments of food, or flakes of mucus cease to come away. This treatment is of course but palliative. Obstruction at the cardiac orifice may prohibit the employment of lavage and may call for more formidable measures. Life may be prolonged by keeping the strictured portion patent by dilating it with esophageal tubes. Through the tubes liquid and finely- divided food may be introduced. In far-advanced stenosis a small rubber tube or catheter may be introduced by one of the nasal passages, retained in position, and through it liquids injected into the stomach. Failing in this, operative procedures may be resorted to. The available surgical procedures resolve themselves into — i. pylorectomy; 2. gastro-enterostomy ; 3. combined pylorectomy and gastro-enter- ostomy; 4. gastrotomy ; 5. jejunostomy; 6. curettage of the cancerous portion of the stomach. At the pylorus the disease is more accessible, and if diagnosed at an early stage and operated upon before the glands becomes in- volved or adhesions have formed, the operation of pylorectomy is indicated. The history, so far, has not been very encouraging. Bremer col- lected 72 cases with a mortality of 76 per cent. Winslow found prac- tically the same ratio in a smaller number of cases. Of 18 cases which I have been able to collect in the past two years, 8 recovered and 10 died. The time may come when a remedy for cancer will be found, but at present our hope for radical cure lies in early diagnosis and complete removal. Could these two conditions be complied with, the results following pylorectomy would be much more favorable than our present figures show. Gastro-enterostomy is a palliative operation, and shows better results than pylorectomy. The mortality is lower and prolongation of life is from two months to a year or more, while in pylorectomy the immediate dangers of the operation are much greater, and in those who survive the disease proves fatal in a period varying from four to eight months. In the early operations, according to Bill- roth, the mortality was 50 per cent. Liicke of Strasburg reduced it to 31 per cent. Gastro-enterostomy does not cure the disease, but it very often brings about a very noticeable improvement in the local and general conditions, showing what an important part the pyloric stenosis plays in the production of many of the symptoms. The pain also disappears. This is explained by the fact that the stomach-contents no longer come in contact with the cancerous ulceration, but pass directly into the small intestines along the new route opened up by the operation. This is why in similar cases the employment of lavage is followed by so much relief (Mathieu). In the Annals of Surgery for December, 1887, Dr. Bernays of St. Louis described an operation whereby, after making an incision in the walls of the stomach, he removes by curette or other suitable instrument INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 229 cancerous growths bulging into the stomach-cavity. His method con- sists in — first, an accurate examination of the outside of the stomach. He then fixes a fold of the stomach to the parietal wound by numerous sutures. The stomach is now opened and its lips carefully stitched to the lips of the wound in the parietes. The stomach-cavity being com- pletely shut off from the abdominal cavity, he proceeds with fingers and curette to tear and scrape away masses of the growth. Bleeding is free, but soon ceases. The results of the operation in several cases have been fairly satisfactory, but a radical cure cannot be relied upon. Stricture of the Cardiac Orifice. — Stenosis of either orifice of the stomach may be a result of carcinoma, or may be due to the cicatricial contraction which follows the healing of an ulcer or a wound caused by a foreign body. The first symptom to attract attention to stenosis of the cardiac orifice is a gradually increasing difficulty in swallowing solid food. Liquids can pass through the narrowed opening, but with less rapidity than in the normal condition ; solids are regurgitated. The epigastrium is often retracted and the stomach collapsed, strongly contrasting with the full epigastrium and dilated stomach which attend stenosis of the pyloric orifice. The passage of olive-pointed bougies, as in the case of esophageal stricture, will confirm the diagnosis. The question of malignancy must be settled by the age of the patient and the history of the case. Stricture of the pylorus is in the vast majority of cases due to car- cinoma. As the lumen of the pylorus becomes lessened, and there is increasing obstruction to the passage of the gastric contents toward the intestine, dilatation of the stomach results, and is a prominent- symptom. A case of pyloric stricture has a history of long-continued dyspepsia, and every chronic dyspeptic should be carefully examined for this condition. It is not uncommon to find such a stomach rejecting food which has remained in it for days or even weeks. If the stomach-tube be used, the contents may be found to amount to several quarts, and the dis- tended organ may reach considerably below the umbilicus. The pres- ence of a tumor in the pyloric region must not be depended upon as a diagnostic point, for, although the absence is indicative of cicatricial stenosis, some of the worst cases of cancerous stricture afford no evidence of a tumor. Einhorn thus tabulates the differential diagnosis between benign and malignant stenosis of the pylorus : Differential Diagnostic Points. Benign Stenosis of Malignant Stenosis of Pylorus. Pylorus.

Treatment. — Non-cancerous stricture of the cardiac orifice should be treated by the introduction of bougies gradually increased in size until the largest instruments can be passed. Nor should the treatment cease at this stage. Full-sized bougies should be passed once or twice a week to prevent recontraction. When this method of treatment fails, gas- trostomy must be resorted to for the double purpose of supplying the stomach with food and of dilating the stricture from below. The manner of carrying out this procedure is described under Esophageal Stricture. At the pyloric orifice the measures to be adopted are forcible dilata- tion through an opening in the stomach, the various plastic operations, and gastro-enterostomy. Forcible dilatation was first practised by Loreta in 1883. He made an incision in the stomach a little nearer to the pylorus than to the cardiac end. Through this opening he introduced the index finger of the right hand and passed it through the stricture. The fore finger of the other hand was then inserted, and by separating the fingers the Fig. 105. Pyloroplasty: i, linear incision ; 2, the final result. The lower series of figures show the transformation of the horizontal linear incision (3) into the oval (4), the sutures (5) converting it finally into (6) a vertical linear incision (Heineke and Mikulicz). stricture was forcibly stretched. The gastric opening was closed, as in gastrotomy for other purposes. This operation is attended with con- siderable danger, and has been largely replaced by the pyloro-plastic operation of Heineke and Mikulicz. The operation consists in making a longitudinal incision at the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 23 1 pylorus, and then suturing it so that it becomes transverse. First Step : After preparation of the patient by washing out the stomach with boracic-acid solution or salicylated water, an incision is made in the middle line from the ensiform cartilage to the umbilicus, the pylorus brought to the opening and packed around with sponges. Second Step : An incision is made into the pylorus and extended one inch along the stomach and one inch along the duodenum (Fig. 105). Third Step : Place a tenaculum at the middle of each side of the pyloric incision and draw the edges apart. The line of incision will thus become transverse to the axis of the stomach. In this position two rows of sutures are applied — first at the angles, and lastly in the central portion of the wound. The results of this operation have been very encouraging. It is attended with no more danger than a gastrostomy, and when properly performed recurrence of the stenosis is impossible. For cancerous stenosis it is of no value. Gastro-enterostomy is the operation by which a communication is established between the stomach and the upper part of the small intes- tine. Wolfler was the first to propose and practise this operation. His technique has been improved upon, and at the present time operators resort to one of two methods — the approximation by Senn's decalcified bone-plates or the anastomosis by Murphy's button. The junction with the intestine should be made from twenty-four to thirty inches below the pylorus. As this point is difficult to find, the following directions may be useful : The first loop of intestine presenting itself at the abdominal wound should be brought out and held by an assist- ant. The operator then follows the intestine in one direction. If this happens to be toward the pylorus, the intestine will be found to grow paler and the walls thicker as the duodenum is approached. The duodeno-jejunal fold is taken as a landmark, and a point twenty-four to thirty inches from it is selected for the intestinal opening. Should the operator find that the bowel becomes thinner and its color increas- ing to a bright red, he may know that he is going away from the pylorus, and must drop that part and start out in the opposite direc- tion. The application of the bone-plates or button is the same as in intestinal anastomosis, described already. Dilatation of the Stomach. — This is a condition attended with much more serious consequences than might at first thought appear. A dilated stomach may be defined as one that cannot empty itself (Mathieu). A distinction must be made between distention and dila- tation. A distended stomach gradually disposes of its contents, and at the end of the interval between meals, as in the early morning, the organ is empty. A dilated stomach, on the other hand, has not the power to empty itself, and in it may be found food which has remained there for days or even weeks. This retention of food is followed by fermentation and the production of toxic substances, so that the patient is poisoned by the material formed in his own stomach. An extreme dilatation of the stomach may be regarded as a fatal disease unless relieved. It is as serious in its effects as cancer of the pylorus. Causes of Gastrcctasia. — i. Mechanical dilatation due to obstruction of the pylorus and to organic changes in the wall of the stomach. Of 232 SURGICAL DIAGNOSIS AXD TREATMENT. this variety the great majority of cases occur in connection with can- cer of the pylorus. Chronic gastritis leads to atrophy of the muscular tissues, with loss of contractility and elasticity, and lastly to dilatation. 2. Hyperchlorhydria, or the excessive secretion of hydrochloric acid, is a frequent cause of dilatation. Such cases often present symptoms which closely resemble gastric cancer. The presence of hydrochloric acid in large quantities readily settles the diagnosis. Early treatment is of the utmost importance, for it not infrequently happens that what would be only a temporary dilatation may become permanent, even after the hyperchlorhydria has disappeared. 3. Atony of the Stomach. — In this variety the patients suffer from dyspepsia of nervous character and the disease is purely medical. Proper treatment resorted to at an early period can be relied upon to prevent dilatation. Symptoms of Dilatation. — When stricture of the pylorus is the cause, there is usually a feeling of weight at the epigastrium or there may be pain more or less severe. Acid eructations often prove trouble- some, and there is a peculiar kind of vomiting which is pathognomonic. It occurs at long intervals, two or three days, and is then very copious. Pints or quarts of liquids are ejected containing particles of food but little changed. This is particularly noticeable if a patient has eaten Indian corn, peas, beans, or other vegetables. Sometimes the vomited matter contains blood. If red in color, it is suggestive of gastric ulcer; if black, it indicates cancer. If the stricture is in the duodenum and below the entrance of the common bile-duct, large quantities of bile will flow backward into the stomach and form an important con- stituent of the vomited matter. The patient should be given a test breakfast, and about an hour afterward the stomach-tube should be passed. If a large amount of fluid is removed at this examination, the diagnosis of dilatation may be safely arrived at, and especially if unchanged food be observed or food that has lain in the stomach for days. Having emptied the stomach, it can be distended with air before the tube is removed. In many cases the form and size of the organ can be seen by the bulging of the abdomen ; by percussion it can be accurately mapped out. Roughly speaking, a stomach is dilated if it comes below a line drawn between the umbilicus and the line of the false ribs. When dilatation attends hyperchlorhydria the pains in the stomach are delayed, coming on three or five hours after a meal. Frequently the patients are aroused from sleep by the pain, which persists until vomiting occurs and affords relief. Remote effects of gastric dilatation may be summed up as follows : In the nervous system, neuralgia, headache, insomnia, melancholia, nightmare, giddiness, and disorders of vision ; in the liver, congestion and enlargement. The respiratory system is affected, as evidenced by bronchitis, asthma, and pharyngitis. Albuminuria and peptonuria are evidences of kidney-involvement. Treatment. — In cases due to atonic dyspepsia regulation of the diet and washing out of the stomach will greatly aid the medical treatment ; it is seldom that the dilatation is so great as to necessitate operative measures. When hyperchlorhydria is the cause the stomach-tube will INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 233 be found invaluable. Washing out the stomach before bedtime ensures rest for the night and saves the mucous membrane from contact with irritating gastric fluids. Mathieu advocates evacuation of the stag- nating liquid once a day, actually washing out the viscus only two or three times a week. Dilatation due to stricture of the pylorus demands a surgical ope- ration. When the stenosis is cicatricial, forcible dilatation or a pyloro- plastic operation is indicated ; when the obstruction is cancerous, gastro- enterostomy is the best. One of two operations may be resorted to — gastro-enterostomy, which deals only with the obstruction, or a partial gastrectomy, which removes the pylorus and a part of the stomach, thus diminishing the size of the dilated organ. Out of 18 cases of gastro- enterostomy collected by Lowenstein there were 6 deaths ; in 21 cases of resection of the pylorus there were 7 deaths. In all cases of dilata- tion particular attention should be paid to the following points : The food should contain the greatest possible nutriment in the smallest bulk ; it should be finely divided, so as to come speedily in contact with the gastric juice and leave as little residuum as possible. Meat- powder, milk, and the farinas are specially useful. The diet should consist of articles which are least likely to undergo fermentation. On this account sugar, alcohol, and vinegar should be avoided. The muscular action of the stomach should be increased by the use of strychnin, ipecacuanha, electricity, massage, etc. Antisepsis of the stomach should be, as far as possible, secured by the avoidance of fermentable food and by frequent washings of the stomach. Patients soon learn to carry out this by themselves, and what is at first a very disagreeable procedure becomes a source of great comfort. In the words of Ewald, " Lavage is the sovereign remedy for dilatation." IV. DISEASES AND INJURIES OF THE INTESTINES. Examination of the Intestines. — Inspection may give us considerable information. A solid tumor, such as a carcinoma, causes the abdominal wall to bulge outward. Obstruction of the lower por- tion of the small intestine is often attended with tympanites and pain in the umbilical region ; that is to say, in the normal position of the bulk of the small intestine. Peristaltic action of the intestine in an ex- aggerated degree may be seen through the abdominal wall when there is obstruction and the intestine is making strong efforts to overcome that obstruction. General distention of the abdomen and tympanites form a very unwelcome sight after celiotomy, and stand out in strong contrast to the flat abdomen which is the joy and pride of the ab- dominal surgeon. By palpation we ascertain the presence of tenderness. A dull diffused pain is a common accompaniment of intestinal catarrh ; an acute diffuse pain is an indication of general peritonitis. Tenderness in the right iliac fossa is a characteristic of typhoid fever, appendicitis, and intestinal tuberculosis. In the left iliac fossa it is a symptom of trouble in the descending colon, and is commonly found in dysentery. When tenderness is very acute and shifting about, it is strongly suggestive of invagination of the small intestine. 234 SURGICAL DIAGNOSIS AND TKEATMENT. Having settled the question of tenderness, we further use palpation to search for tumors. By a rotary motion of the abdominal wall over the subjacent structure the presence of tumors can be detected long before they can be recognized by inspection. When a tumor of the intestine is felt it must be placed in one of three classes: i. Fecal masses or scybala, found in the large intestine : this is the only tumor which retains an indentation. 2. Tumors of the intestine, carcinoma, sarcoma, etc. : they are often lobulated and of firm consistence. In the small intestine these tumors are apt to change their location, while in the large intestine they are more fixed. 3. Invagination of one portion of the small intestine into another or of the small into the large intestine. Tumors of this character are round and smooth, the pain is violent and comes in paroxysms. The other indications of intussusception described under Acute Intestinal Obstruction are also present. Tumors at the junction of the transverse with the descending colon are usually difficult to detect, for they lie deep and are liable to be confounded with tumors of the kidney or spleen. Percussion. — In health every part of the intestine gives forth a tympanitic note, the pitch varying according to the amount of fluid or gaseous contents. The size of the intestine cannot be accurately deter- mined by percussion, nor can we always determine the boundary be- tween colon and stomach or between the part of intestine above and that below a constriction. Tumors of the intestine may grow to a considerable size and yet not produce dulness on percussion. This diagnostic measure is therefore not so reliable as palpation. Never- theless, there are cases in which it proves very satisfactory. By noting the difference in pitch between the stomach, colon, and small intestine in the normal area occupied by each we can map out their relative positions. Tumors which in light percussion elude us are often detected when examined by " deep percussion " and when the over- lying coils of intestine are pushed aside. Inflation of the colon with air facilitates percussion. For this purpose carbonic-acid gas has been considered preferable to air, for the reason that its irritating character causes closure of the ilio-cecal valve, while air passes through and distends the small intestine as well. The phonendoscope is of great utility in examining the intestines. The manner of using it has been described in Examination of the Abdomen. Diseases of the Intestines. Cancer of the intestine is a disease of advanced life. Its onset is obscure. Generally there is constipation, frequently diarrhea, always emaciation. The first warning of anything of a serious nature may be obstruction of the bowel. The growth may constitute a palpable tumor. In examining for it the patient may with advantage be placed upon his hands and knees, so that the intestines fall toward the pal- pating hand instead of away from it. The tumor is very illusive. One day it can be felt with the greatest ease, the next you may search for it in vain. If connected with the small intestine, the neoplasm is freely INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 235 movable ; if in the colon, it is firmly fixed. It is always tender, and as it increases in size the growth is in the direction of the axis of the intes- tine. Its surface is lobulated or knotty, and it is incapable of receiving an impression like a fecal tumor. You are liable to fall into the trap of calling it sciatica if the growth is in the lower end of the colon, for the sacral region is the part to which the patient refers his pain. It may be difficult to diagnosticate the portion of the bowel which is the seat of the disease. In the small intestine cancer, as a rule, takes an annular form, and on this account the leading feature is sten- osis. The symptoms of the stenosis will vary according to position. In the duodenum we cannot always undertake to say which portion is affected. The first portion is horizontal in direction, is almost sur- rounded with peritoneum, is the most movable, and lies nearest to the abdominal wall. It must be regarded clinically as a part of the stomach and partaking of the diseases of the stomach. Hence cancer of this portion cannot be distinguished from cancer of the pylorus. A very important dividing-line is the ampulla of Vater. Stenosis below this point is characterized by a permanent backward flow of bile and pancreatic juice into the stomach. Cancer which involves the ampulla has characteristics which partake of the symptoms found in both the first and third portions. In the other portions of the small intestine the presence of a movable tumor in the long axis of the bowel will afford our strongest evidence. In the sigmoid flexure and cecum the tumor is generally distinct. In all cases blood is not infrequently passed by the bowels, and there even may be masses of cancerous tissue. The rectum is the portion of the intestinal tract in which the disease can be detected with the greatest degree of certainty. One of the ear- liest symptoms is pain in defecation. Whenever this is complained of an examination of the rectum should be made as a matter of routine. As the disease advances the pain increases and is more or less constant. Blood and mucus are passed in the stools, and in many cases there is morning diarrhea. In making an examination of the rectum the patient should lie upon the left side. The finger is vastly superior to any speculum. The sen- sation conveyed to the finger by cancer is peculiar, and w^hen once recognized cannot be mistaken for anything else. If the growth be epithelioma, the mucous membrane will be found thickened, firm, and freely movable, at least before the disease has reached an advanced stage. If scirrhous cancer be present, hard nodules will be found involving the submucous tissues, and later infiltrating the other tissues and involving the glands, the liver, and other organs. Two diseases are likely to be mistaken for cancer of the rectum — simple ulceration with inflammatory thickening and syphilitic ulceration with or without stricture. In simple ulceration there is usually a his- tory of dysentery or of the presence of foreign bodies. The ulcer is clean cut, and has the same kind of discharge as simple ulceration in other parts of the body. There is no infiltration or gland-involvement, and the growth does not show a disposition to break down. Syphilitic deposit w^ith stricture must be carefully taken into con- sideration in the diagnosis, as it is a common source of error. The 236 SURGICAL DIAGNOSIS AND 7'REATMENT. history, the condition of the throat, the skin, the scalp, and the bones, will usually clear up any doubt. Treatment. — Carcinoma of the intestine only requires surgical inter- ference when it is producing obstruction. In the duodenum gastro- enterostomy is in many cases the best that can be done. In other por- tions of the small intestine resection with circular enterorrhaj^hy is the operation which is most radical and easiest of performance. Care must be taken to remove the corresponding portion of mcsenteiy, lest the can- cerous infiltration should spread through the mesenteric glands. Cancer of the rectum must be treated according to the extent of the disease. When the highest point of the cancerous mass can be reached by the examining finger, and there is no involvement of the glands or neighboring tissues, excision of the growth should be under- taken. When the upper limit of the disease cannot be reached, or when the vagina, the prostate, etc. are affected, excision of the rectum should not be attempted. < Operatioft. — For several days before the operation the intestines should be well emptied by purgatives and the rectum washed out with injections of boric-acid solution. The patient is placed in the lithotomy position, and a final flushing given to the rectum, the bladder emptied, and the buttocks elevated. If the growth is small and freely movable and confined to the posterior wall of the rectum, it will be sufficient to dilate the sphincter, draw down the rectum, excise the growth by a transverse elliptical incision, and close the wound with catgut sutures or pack it with iodoform gauze. The great majority of cases, however, will require a more extensive operation. An incision is made from the anus back to the coccyx in the middle line or a little to the left. Crescentic incisions, one on each side, are made to surround the anus. These incisions should be through the skin when the sphincter ani is diseased, through the mucous membrane when the sphincter is healthy. The bowel should then be dissected up quickly behind, and bleeding arrested by pressure- forceps. In front of the rectum the dissection must be slower, as there is danger of getting into the prostate or vagina. When the bowel has been separated well above the disease, cut it off with curved scissors. If in this procedure the peritoneum has been opened into, it must be closed with sutures. A large drainage-tube guarded with a chemisette \z inserted and loosely packed with iodoform gauze. Drawing down the divided gut and suturing it is no longer practised, as the tension is too great and there is a risk of retaining secretions which interfere with healing. The packing can be removed at the end of forty-eight hours. Daily injections with boracic-acid solution should then be employed. W' hen granulation is well advanced cicatricial stenosis must be guarded against by passing a full-sized bougie daily, beginning about the end of the second week. Kraske's operation has several advantages over the method just described, inasmuch as it allows more complete access to the bowel. By it a greater extent of the rectum can be removed, and the external wound need not be extensive. The incision is made from the anus to the second bone of the sacrum in the middle line. The soft parts are then separated from the bone on the left side until the edge of the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 237 sacrum is freely exposed. The coccyx is removed, the sacro-sciatic ligaments divided, and, if necessary, the left side of the sacrum partly chiselled away. This gives complete access to the rectum. The pos- terior part of the bowel is cut open down to the sphincter, and then, by transverse incisions above and below the cancerous growth, the diseased portion of the rectum is removed. The external wound is packed with iodoform gauze, and the rectum irrigated twice a day, as in other operations. In far-advanced cases of cancer of the rectum, when the disease goes high above the point which can be reached by the examining finger and causes obstruction of the bowel, colostomy is the proper treatment. Intestinal Obstruction. — Intestinal obstruction may be con- sidered under two heads : (i) Acute obstruction, in which the symptoms come on suddenly without any previous history of disease ; • (2) Chronic obstruction, where there is previous intestinal disease and a slow gradation from partial to complete occlusion. Acute Intestinal Obstruction. — The almost uniform failure to cure acute intestinal obstruction by medical treatment has led the profession to look to surgery as the only hope of rescuing a class of cases other- wise practically hopeless. The operation has a long but unfavorable history. For centuries it has been approved and as strenuously con- demned. Almost uniform disaster has attended its employment until recent years, when the advancement along the whole line of abdominal surgery has thrown new light upon its use and inspired its advocates with new hope. Acute intestinal obstruction practically exists under three conditions : 1. Intussusception; 2. Volvulus ; 3. Strangulation by bands or through apertures. By intussusception or invagination of intestine is meant a prolapse of a part of a bowel into the lumen of the adjoining part. One-third of all the cases of obstruction are due to this cause. One portion of bowel grasps — swallows, as it were — the portion immediately above it. Grasping the bowel as if it were food, more and more is invaginated, until, in extreme cases, several feet of bowel may be involved. The name intussuscipicns is given to the receiving portion of intestine, while the part invaginated is called the intussusccptuni. This unnatural condition is followed by serious consequences : adhe- sions form between the opposed surfaces of peritoneum, the walls be- come swollen and inflamed, curving of the intestines by dragging of the mesentery is produced, intense congestion results, followed by discharge of blood from the rectum or gangrene, and finally complete obstruction. According to Senn, sloughing is caused by obstruction to the return of venous blood by constriction at the neck of the intussusception. Curiously enough, intussusception is very commonly found in the post-mortem room, one body in four showing this condition. It is also believed that many cases right themselves, and that a large proportion of cases of acute colic belong to this class (Greig Smith). 238 SUKGICAl. DIAGXOSIS AND TREATMENT. The most common situations arc — (i) in the small bowel, and gen- erally the lower part of the jejunum. It occurs in the ileum in the proportion of one case to four in the former class. (2) The colon may be the seat of an intussusception at any part of its course, but it is by no means common, and when it does occur only a small portion of bowel is involved. (3) The most common of all situations is the ileo- cecal region, and here it may be produced by the ileo-cecal valve form- ing the apex of the intussusception, and, passing up the colon, followed by the cecum and ileum, or the ileum may pass through the ileo-cecal valve and be invaginated up the colon. A rare and complicated variety is where a primary invagination of the end of the ileum is either passed through the valve into the colon or invaginated into the colon along with the cecum (Greig Smith). By volvulus is meant an occlusion of bowel by torsion or rotation round its axis of attachment. This may be caused by simple twisting or two suitable coils may be intertwined. The sigmoid flexure is the most common situation, constituting two- thirds of all the cases. The tendency in this direction is increased by the shape of the bowel, the length and loose attachment of the mesen- tery, and the tendency of the bowel to become overloaded and dis- placed by collections of feces. The bowel may be twisted once, twice, or even three times around the axis. Next in point of frequency is volvulus of the cecum or cecum and colon adjoining. Here obstruction is easily brought about ; even an acute flexure of the cecum is sufficient to block the passage; it may be produced by intertwining of the small intestine. In the ascending colon the disease is rare and is due to anatomical abnormality. In the cecum it may be subacute or chronic. The small intestine is rarely the seat of volvulus. An old hernia with a long mesentery may be a predisposing cause. Strangulation by tabids or through apertures is internally what an ordinary hernia is externally. In either case a loop of bowel is con- stricted by a tight, unyielding opening, obstructing its lumen and com- pressing its vessels. In both cases strangulation results, producing symptoms and calling for treatment almost exactly alike. Bands of organized inflammatory material, the so-called " peritoneal false ligaments," occur in an endless variety of forms. They are the result of old attacks of peritonitis. They may pass from coil to coil of the intestine, or from organ to organ, as the liver and uterus, or from the intestine to the abdominal or pelvic wall. Tubercular glands may form their starting-point, and the bands may stretch from gland to gland in the mesentery, or, springing from one side of a gland, may bend around the intestine and become attached to the opposite side of the same gland. They may be round or flat, short or long, single or multiple. The bowel may slip under a band when it is short, or it may be caught in a loop or twisted when the band is long. The small intes- tine, most commonly the lower part of the ileum, is likely to be the seat of the strangulation. The prog7iosis of acute intestinal obstruction is exceedingly un- favorable. In ordinary strangulated hernia the chances for recovery are almost nil, yet there is a bare chance, for gangrene of the bowel INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 239 may take place with the formation of a false anus. In strangulation by bands there is not even a chance. If gangrene takes place, there is but one termination — death. It is believed that spontaneous recovery after volvulus is unknown. Intussusception in a very small proportion of cases may right itself and the patient recover, but such fortunate terminations are few and far between. The diagnosis of acute obstruction is of the utmost importance, and in many cases exceedingly difficult. The symptoms are, roughly speak- ing, those of strangulated hernia in an aggravated form. The abdom- inal pain is agonizing. In some instances, however, it is not severe, and frequently it is intermittent in character. The severity of the pain appears to bear a direct ratio to the force of the peristaltic movements ; and this explains the intermittent character of the suffering. When constric- tion takes place, the bowel makes an effort to overcome it, and wave after wave of peristaltic movement is directed against the obstruction. The motions grow stronger and stronger, and the pain increases in seventy till from exhaustion of the bowel-muscle the movement ceases and the pain subsides. After a period of rest, the wall of the intestine, having regained its tone, renews its fruitless attack, and with this new effort the pain returns to its former intensity. It may be like severe colic, or it may convey the sensation of a tight band around the abdomen. Be- sides pain, the prominent symptoms are vomiting, constipation, collapse, and tympanites. Temperature is of little value as a symptom. It is usually sub- normal, and even when peritonitis occurs it may remain subnormal to the end. Vomiting is one of the early and most important symptoms, and we may set it down as a rule that the higher the obstruction the more violent is the vomiting. At first the ordinary contents of the stomach are voided, either in gushes without much effort or with violent retching. Later the vomit is bile-stained, then of a dark, grumous material, the so-called coffee-grounds. Finally, fecal mat- ter is vomited more or less diluted. This requires that the constric- tion should not be higher than the jejunum. Constipation is of the most obstinate and insuperable nature. When once the intestine below the seat of constriction is emptied, absolutely nothing passes from the bowels, except in certain cases of intussusception, when blood may escape. Local meteorism is a symptom upon which von Wahl lays great stress. The intestine above the seat of obstruction becomes distended, and the enlargement gradually continues along the course of the con- stricted bowel. The peristaltic action is also increased, and both the contour of the bowel and its peristaltic movements may be seen through the abdominal wall. Rosenbach, Rosin, and others claim that in complete obstruction of the ileum there is always indican in the urine. When the obstruction is in the colon or high up in the small intestine, this reaction is not produced. The simplest test is to boil a small quantity of the urine in a test-tube and add nitric acid, drop by drop. The urine turns red, and throws down a precipitate of a similar color. On shaking a violet- 240 SURGICAL DIAGNOSIS AND TREATMENT. colored foam is produced. So long as this reaction can be detected in the urine Rosenbach considers the case one of great gravity, and its continuance after an operation proves that the obstruction has not been relieved. It disappears within twenty-four hours after the relief of obstruction. The fallacy in this symptom lies in the fact that it may exist in a variety of morbid conditions.' Diagnosis from Other Diseases. — Every case of abdominal pain, and especially when the pain is attended with vomiting, should be closely investigated for hernia. The ordinary hernial outlets should one by one be examined, for strangulated hernia is the condition most likely to be mistaken for acute obstruction. Appendicitis probably comes next, but here there is the history of localized indanmiation, fever rising to and not above ioi° or 102°, with great tenderness over the position of the appendix, and possibly the formation of a tumor. Diagnosis of the Locality of the Obstruction. — For diagnostic pur- poses it is convenient to divide the intestine into three portions : 1. TJie Duodenum and Jejunum. — When acute obstruction occurs at the duodenum or upper portion of the jejunum the first indication is sudden and intense pain at the epigastrium, followed by violent vomit- ing. This vomiting is constant until the obstruction is relieved or the patient dies. It never becomes stercoraceous, for it is too high up to contain fecal matter. The parts above the constriction have a tendency to become dilated, the parts below to become collapsed. Hence we often find the stomach dilated and tympanitic, while the abdomen below is flat and contracted. The bulk of the bowel being below the con- striction, flatus and feces may pass naturally. 2. The Ileum, or Lower Part of the Jejunum. — The constriction being much lower than in the preceding, accumulation of gas is a marked symptom, and we consequently find the abdomen becoming rapidly distended. Vomiting does not come on so suddenly, but it is persistent and changes in its character — first normal stomach-contents, next bile, and lastly fecal matter. The pain is colicky, paroxysmal at the beginning, but soon becoming persistent. 3. Colon and Sigmoid Flexjire. — Here the symptoms come on more slowly. The patient can often point out the seat of obstruction by the localized pain. Tympanites is a very marked symptom after the first few days. No fecal matter or flatus passes from the bowel and the rectum is empty. Is it possible to diagnose the variety of obstruction ? In certain cases it is. An examination by the rectum will, in a small proportion of cases, discover the bowel descending in intussusception. This form occurs particularly in children. The pain comes in waves, gradually gaining in intensity till a climax is reached, when it for a time subsides. Vomiting in this form is not so characteristic a symptom as in the other varieties. It may be a feature from the outset or it may not appear till late ; it may be severe and copious or slight and almost pain- less, or it may not exist at all. The abdominal wall is seldom dis- tended ; indeed, it may even be retracted. There is one symptom, however, which is valuable, and that is a discharge of blood from 1 American Year-Book of Medicine and Surgery, 1896. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 24I the rectum, which is often associated with tenesmus and diarrhea. If besides these a tumor can be found by palpation through the parietes, we have about all the evidence we can obtain that the case is one of intussusception. So rapid is the progress of the disease that death may take place within twenty-four hours. In more favorable cases the fatal event is postponed for several days ; in those still more favorable the condition may become chronic and last for several weeks. In volvulus of the large intestine there is usually a previous history of constipation. It is commonly found in males above middle life. Its usual situation is at the sigmoid flexure. The pain comes on suddenly, is felt at the hypogastrium or in the back ; constipation is marked from the first ; vomiting is a later development and is not necessarily severe. Feculent vomiting occurs in about 1 5 per cent, of the cases. In later stages of the disease there is tenderness on pressure. Volvulus of the small intestine and strangulation by bands so closely resemble each other in symptoms that it is probably impossible to distinguish them. In both the pain is severe and continuous from the outset, with frequent exacerbations, and is felt most commonly at the umbilicus. There is no tenderness on pressure. The vomiting begins early, is frequent, copious, and becomes stercoraceous about the fourth day. In the following table I have tried to place .side by side the diagnostic differences in the three forms of obstruction : Strangulation by Bands. Volvulus. Intussusception. Young males. Age. Males above forty. Young children. At umbilicus ; severe from the beginning. Pain. Hypogastrium or back ; comes on at once, but not so severe ;. intermits. Prominent ; comes in waves. Early, frequent, copious, stercoraceous, fourth or fifth day. Vomiting. Late or not at all ; never very urgent ; 1 5 per cent, of cases feculent. Very variable symptoms. Complete from first. Not at first marked ; no tumor. Constipation. From first. Abdominal Distention. Rapid accumulation of gas, causing great distention ; no tumor. Blood from bowels, with tenesmus. Usually absent ; tumor felt through parietes or in rec- tum. Die about the fifth day. Duration. Average six days. Twenty-four hours to several days or weeks. Treatment. — Perhaps no condition requires more promptness, accu- racy, and good judgment than intestinal obstruction. Temporizing in the diagnosis may allow the only chance of saving the patient to slip 16 242 SURGICAL D/AGXOSIS AND TREATMENT. away. Purgatives, althouf^li apparently demanded, may produce irre- parable injury. If medical treatment be persisted in till the condition becomes desperate, no amount of surgical skill can make amends for an opportunity for ever lost. As regards medical treatment little need be said. When we consider that the condition is analogous to stran- gulated hernia, the question of drugs becomes a secondary matter. The chief value in medical treatment is the rehef of the distressing symp- toms that are ever present. Vomiting is one of these. Food by the mouth is not only useless, but positively harmful. Alimentation must be kept up by rectal enemata of beef-tea, brandy, and other easily- assimilated nutriments. When the vomiting is feculent the stomach should be washed out wath mild antiseptic solutions, such as salicylate of soda. This greatly relieves the patient's discomfort and, according to Jessett, arrests peristaltic action. For the relief of pain and the lessening of peristalsis opium in small and repeated doses is valuable. One serious objection to its use, however, is that it is apt to mask the xsymptoms, and, by giving a feeling of false security, to prevent the sur- geon from making an early diagnosis. Enemata or aperients are dan- gerous, as they increase the peristaltic action of the bowels, aggravate the vomiting, and hasten collapse. Surgical Trcatnie7it. — Surgical procedures may be resorted to for two objects — viz. (i) for diagnosis, and (2) for relief of the obstruction. It is not discreet to advocate exploratory incisions as a routine prac- tice, but when delay is attended with such disastrous consequences as often happens in these conditions, if ever an exploration is advisable it is here. When there is positive evidence of acute obstruction due to a constriction, operation with the utmost promptness is demanded, for we might just as reasonably treat a strangulated hernia by the expectant method as to trust to medical treatment here. The diagnosis should be made, if possible, and the operation resorted to, before fecal vomiting and prostration have set in. Various minor procedures have been employed for the relief of obstruction. These will receive brief mention : Evaaiation of the StomacJi. — This has been mentioned as a valuable remedy for the relief of stercoraceous vomiting. Distention of the Colon. — The injection of fluid into the colon is a favorite remedy, and one almost instinctively resorted to. Many cases of intussusception have been relieved by this method. To be of any use it must be employed early, before adhesions have formed or obstruc- tion to the circulation at the seat of the stricture has taken place. The water employed should have a temperature of 105° to 108*^ F. and should contain a small proportion (0.7 per cent.) of common salt. The fountain syringe from which it flows should be held at a height of four feet, which gives a pressure of about two pounds to the inch. The fluid should be slowly injected, four ounces to the minute (Martin and Hare). This treatment should not be persisted in beyond thirty or forty minutes, and in case of failure abdominal section should be resorted to without delay. Distention with hydrogen gas or with filtered air is now regarded with more favor than the injection of fluid. It is only to be thought of in the early stage of intussusception or volvulus, and great care INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 243 must be taken lest too forcible distention produce ov^erstretching or rupture of the bowel, Maniial Exploration of the Rectum. — In children a digital examina- tion may reveal an intussusception low down. The introduction of the whole hand is a procedure to be discouraged, except under very special circumstances. It is not warrantable, except when the patient is an adult and the surgeon is possessed of a small and slender hand. Puncture of the Intestine. — When there is great distention of the intestine with gas, and the circumstances are such that no more suitable operation can be resorted to, puncture of the bowel by a small aspi- rating needle affords temporary relief It is needless to say that this treatment is unscientific and not to be recommended. Taxis and Massage of the Abdomen. — This method has had its ablest advocate in Mr. Jonathan Hutchinson, who described the pro- cedure in the following words : " The first point in abdominal taxis is the full u.se of an anesthetic, so as to obliterate all muscular resistance. Next (the bowels and bladder being supposed to be empty) the surgeon will forcibly and repeatedly knead the abdomen, pressing the contents vigorously upward, downward, and from side to side. The patient is now to be turned on his abdomen, and in this position to be held up by four strong men and shaken backward and forward. This done, the trunk is to be held uppermost, and shaking again practised directly upward and downward ; whilst in this position copious enemata are to be given. The whole proceedings are to be carried out in a bond fide and energetic manner. It is not to be merely the name of taxis, but the reality, and patience and persistence are to be exercised. The inversion of the body and succussion in this position are on no account to be omitted, for they are possibly the most important of all. I do not think that I ever spend less than a half or three-quarters of an hour in the procedure." It may well be questioned whether this energetic treatment is not attended with as much danger as a carefully executed celiotomy, while it only affords a haphazard means of righting an obstruction. We have to deal with a disease that is invariably fatal in from twenty-four hours to six days. Volvulus has never been known to recover under medical treatment. Spontaneous recovery in cases of strangulation by bands is beyond the bounds of possibility, and recovery in cases of intussusception is a matter of the merest chance. Looking at the matter in this light, the choice is left us either to stand by with idle hands and see our patient die or to make the attempt to save his life by timely operation. The mortality may be fairly stated at 95 per cent, in cases treated without operation. The statistics of celiotomy for obstruction have been studied by many writers, including Schramm in Germany, Delaporte in France, Treves in England, and Whithall, Sands, and Ashhurst in America. Of 346 cases collected by Ashhurst, the mortality was as follows : Intussusception, 65 cases ; mortality, 75.4 per cent. Volvulus, 29 " " 71.4 " " Strangulation by bands, 1 19 " " 67.8 " " 244 SURGICAL DIAGNOSIS AND TREATMENT. In the aererrecrate of \a6 cases from all causes the mortality after the 111 •/- operation was 69.3 per cent. We thus see that the chances m favor of operation are as 95 to 69.3, or a saving of nearly 25 per cent. In Ashhurst's earlier statistics he found the mortality to be 67.6, and argues that, contrary to the history of most operations, the gravity of this one increases rather than diminishes as it is more often resorted to. It must, however, be remembered that statistics of this character are misleading. The difficulty of getting the results of unsuccessful cases must always be great. The operation has hitherto been resorted to in the most hopeless cases, and, as a rule, when every other means had failed and death was imminent. With increasing confidence and dimin- ished fear of operating it is likely that the operation will be resorted to at an earlier period and the main danger wall be eliminated — the danger of delay. An early resort to operation might confidently be expected to bring about such good results as have followed the early use of forceps as compared with ancient practice, or the success which fol- lows early herniotomy. Given a competent operator, cases treated before abdominal distention has come on, before the bowel has become inflamed or gangrenous, before adhesions have formed, before the patient's strength has become exhausted, would it be too much to say that the mortality would be reduced to 1 5 per cent., as predicted by Dr. Greig Smith ? Operations. — Having decided that obstruction exists, the course to pursue, as a rule, would be as follows : Distention with warm water should be given a fair trial, provided w^e are satisfied that the obstruc- tion is recent and there are no firm adhesions nor a gangrenous bowel. Some prefer hydrogen gas or filtered air. The advantage of using warm water is that in the event of failure to overcome the obstruction it fulfils another indication which is a necessary preliminary to operation — /. e. it washes out the lower portion of the intestinal tract. One trial only of this method should be em- ployed. If there is a tumor, showing the probable presence of intussusception, success will be manifested by disappearance of the tumor. In some cases the question can at once be settled, for the tumor remains as large as before, occupying its original position. In such an event we would better proceed to operate at once, without letting the patient come out of the influence of the anesthetic. When there is still doubt as to whether the distention has been successful or not, the patient should be allowed to regain consciousness. The symp- toms will soon decide the question beyond doubt. EntC7'ostomy (iuzspov, the intestine, and azo/ia, a mouth) is the formation of an artificial opening in the intestine by which the contents can be discharged. The operation has by long usage gone under the name of enterotomy (evrspov, the intestine, and to/jltj, an incision). This term should be limited to the making of an incision into the bowel as for the removal of a foreign body. Enterotomy^ as it was improperly called, was first performed by Nelaton on a patient of Trousseau's about the time the great French clinical teacher was delivering those delightful lectures at the Hotel Dieu. Nelaton advocated this operation in cases of intestinal obstruction w^iich had lasted six or eight days, attended with fecal INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 245 vomiting and great abdominal distention. Resorted to under such desperate circumstances and without the aid of modern technique, we need not wonder that the operation was attended with such indifferent success. It has no future, for it will be employed only in cases which from neglect have been allowed to run on till profound collapse has left the patient in such a condition that the only thing possible to save his life is to draw up a loop of intestine, open and drain it. An artificial opening of the bowel through the skin must always place the patient in a pitiable condition. An artificial opening from one part of the intes- tine to another is a different thing, and will take the place of the old operation. Enterostomy is a very simple operation. The abdominal wall is divided by an incision one and a half to three inches in length parallel to and a little above Poupart's ligament, between the anterior superior spine of the ilium and the epigastric artery. Stitch the parietal peri- toneum to the skin by a continuous suture. A loop of distended bowel — which, as a rule, proves to be some part of the lower portion of the ilium — is drawn out and attached by sutures to the abdominal wound. If the case is not very urgent, the bowel need not be opened for several hours. This greatly lessens the risk of infecting the peri- toneal cavity, as it allows adhesions to form between the bowel and the abdominal wound. If the bowel has to be opened at once, great care should be observed in placing the sutures so as to shut off the ab- dominal cavity. A portion of the surface of the bowel about the size of a silver quarter-dollar can be secured to the edge of the wound by fine silk sutures, either continuous or interrupted, and an opening made by scissors or tenotomy-knife large enough to admit the finger. This opening must be kept patent by placing a single stitch on each side to connect the margin of the intestinal wound with that of the parietal opening. Having established the artificial anus, we can utilize it in four ways : 1. We can allow the patient to rally and regain strength, performing a radical operation later. 2. In cases where the obstruction does not admit of removal, as in cancer, the opening can be allowed to remain permanently. 3. Under fortunate but rare circumstances a cure has been effected by enterostomy, the obstruction being removed by spontaneous correc- tion of the mechanical conditions which produced it. 4. When the operation has been performed for fecal accumulation, the fistula may be closed as soon as it shall have fulfilled its purpose. Celiotomy for Acute Obstniction. — This is the operation which deals radically with the obstruction and promises the best results. If possible, a diagnosis should be made before the obstruction has lasted twenty- four hours. Preparation of the Patient. — When there is vomiting, and especially if it be of a feculent character, the stomach should be washed out with a 5 per cent, solution of salicylate of soda. The bowels also should be emptied by a warm-water injection, and an enema of brandy and beef-tea given just before the operation. The skin over the abdo- men, having been washed with warm water and green soap, is next cleansed with ether or turpentine, and lastly with corrosive-sublimate 246 SURGICAL DIAGNOSIS AND TREATMENT. solution, I : 2(XX). Chloroform is the best anesthetic, as it is attended with more placid breathing and there is less venous congestion than when ether is administered. In some cases the patients are so deeply collapsed that general anesthesia cannot be borne. The injection of cocain along the line of incision is then the best means of making the operation painless, and the most that can be accomplished is the forma- tion of an artificial opening in the intestine, as already described under Enterostomy. The Iticision. — For most purposes a median incision midway between the umbilicus and pubes will answer best. It should be long enough to admit three fingers, and can be extended up or down as required by dividing the parietes with strong scissors. It may be set down as a rule that all parts of an intestine above a constriction are distended, all parts below are collapsed. The fingers inserted into the wound should first search for the cecum. Distention at this portion of the intestine means that the colon, sigmoid flexure, or rectum is the seat of obstruc- tion. Collapse here is an indication that the obstruction is in some part of the small intestine, the ileo-cecal valve, or higher up (Jessett). The abdominal incision should be extended as may be necessary ; coils of intestine should be allowed to escape, care being taken to keep them well protected by cloths or flat sponges wTung out of hot water. If the search in the neighborhood of the cecum has been fruitless, the sigmoid flexure should next be examined, for in nine cases out of ten the obstruction will be found in the lower half of the abdomen and in one or other inguinal region. Still failing to find the constriction, a systematic search is to be made as follows : Pick up a loop and, draw- ing it out so that it can be held by an assistant, examine it in one direction ; observe whether distention and congestion increase as you pass along its course. If so, you are getting nearer and nearer the point sought for ; but if the bowel becomes more healthy, push the loop back and continue your search in the opposite direction. Once the cause is found, its removal may be attended with some difficulty. Bands may be divided between ligatures, an opening may be enlarged, as in the case of an ordinary hernia, a volvulus may be untwisted, an intussusception drawn out. When the operation has been resorted to before adhesions have formed or gangrene has com- menced these methods of relief are possible ; but, unfortunately, com- plications and difficulties must often be encountered, and these we shall consider under the different forms of obstruction. Intussusception. — Interference with circulation at the constriction sets in at an early period, and consequently congestion and edema are serious obstacles to reduction. An analogous condition is found in paraphimosis. The swelling and edema must be removed before the telescoped portion of bowel can be relieved. Three maneuvers may be successively tried : 1. Apply steady pressure to the intussusception, and when the swelling disappears draw gently down upon the neck of the intussus- ceptum. 2. Pass a director around between the intussuscipiens and the intussusceptum, and very gently break down any adhesions that may have formed. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 247 3. Failing in both of the above methods, the bowel may be inflated per rectum with water or hydrogen gas, aided by traction and manipu- lation. When invagination has been relieved by one or other of these methods the bowel must be carefully examined : slight rents in its peri- toneal coat should be closed with Lembert sutures of fine silk ; abrasions and gangrenous spots should be protected by omental grafts. It often happens that adhesions have become so firm that they cannot be separated, or the bowel has been so long strangulated that it has become gangrenous. For the first of these complications we resort to intestinal anastomosis, for the second to resection of the gangrenous portion of bowel, intussusception and all. Intestinal Anastomosis. — Where rapids occur in the St. Lawrence River the obstacles to navigation have been overcome by connecting the river above and below the rapids by means of a canal. In like manner we get rid of intestinal obstruction by inosculating a loop of intestine above to a loop below the stricture, and thus compelling the intestinal contents to take a shorter course, by which they avoid the portion of bowel which contains the obstruction. This idea was first suggested by Maisonneuve. Billroth and Von Hacker also gave it considerable study, but the operations were never attended with satis- factory results until Senn designed and carried out the method of forming anastomosis with decalcified bone-plates. As regards the indications for the operation, Prof Senn has arrived at the following conclusions: " i. If the external surface of the bowel presents evi- dences of gangrene, disinvagination should not be attempted, and in such cases resection is absolutely indicated. 2. The resection under such circumstances should always include the whole intussusceptum, but only so much of the intussuscipiens as is threatened by gangrene. 3. If the continuity of the bowel cannot be restored by circular sutur- ing, either on account of the difference in size of the lumen of the resected ends or of inflammatory softening, the same object is attained in an equally satisfactory manner, and more safely, by lateral implanta- tion or intestinal anastomosis. 4. If the invagination is not extensive, but irreducible, and the bowel presents no sign of gangrene, the ob- struction should be allowed to remain, and the continuity of the intes- tinal canal restored by making an anastomotic opening between the bowel above and below the invagination by the use of perforated decalcified bone-plates. 5. If the invagination is extensive, irreducible, and the bowel presents no indications of gangrene externally, the intussusceptum should be made accessible through an incision below the neck of the intussuscipiens, and resected after securing the stump with an elastic ligature, after which the obstruction is permanently excluded by an intestinal anastomosis. 6. In irreducible colico-rectal invagination, or when this form of invagination has been caused by a malignant tumor, the intussusceptum should be drawn downward and removed by the operation devised by Mikulicz." Manner of Using Bone-plates {¥\g. 106). — Having selected the two loops which are to be united, (i) shut off the remainder of the bowel from the part to be operated upon by clamps, rubber bands, or strips of iodoform gauze, two for each loop. (2) Make in each loop a longi- 248 SURGICAL DIAGNOSIS AND TREATMENT. tudinal incision on the convex side of the intestine at the part most dis- tant from the mesentery. This incision should be two to two and a lialf inches in length. Allow the contents of the loop to escape and wash with sterilized warm water. (3) Slip a bone-plate into each in- cision. The lateral threads are made to perforate all the coats of the bowel ; the end threads are left lying in the angles of the wound (Fig. 107). (4) Tie the threads and allow the knots to lie between the serous sur- faces. (5) Additional security is gained by inserting Lembert su- FlG. 106. — Senn's decalcified bone- plate.

Scratching the serous surfaces with the point of a needle may hasten their union when brought into apposition. This, however, is of doubtful value. Serous surfaces readily unite without this, and the dangers of infection through even a slight scratch should not be overlooked. Abbe of New York objected to Senn's bone-plates on account of the difficulty of getting plates of bone large enough for use in the human subject, the trouble required for preparing them, and their tendency to warp and bend, and has devised rings composed of several strands of thick catgut around which are wound spirally other threads of the same material. Plates composed of raw turnip or potato have been used. Murphy of Chicago has invented a very ingenious and easily applied "button," which can be utilized with great rapidity and is suitable for any operation to which bone-plates can be applied.

Notwithstanding these Fig. 113. — Showing incision into the intussuscipiens, the intussusceptum being seized by volsellum forceps and cut across with scissors (first stage) (after Jessett). Fig. 114. — Showing intussusceptum detached, and the divided end of intestine sutured (second stage) (after Jessett). Fig. 115. — Showing incision in the intussuscipiens closed, and the neck of the intussusceptum united at end with sutures (final stage) (after Jessett). criticisms most excellent results have been obtained by this method, and the " button " is gaining in popularity. The method of using the button is shown in Figs. 109-112. In each loop of intestine to be united a purse-string suture is placed, as shown in Fig. in. The intestine is then opened, and one half of the button is grasped in a pair of hemostatic forceps inserted into the opening. The purse- INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 25 I string suture is then tied, care being taken to include all the free edges of the incision, so that they will come between the halves of the button. The other loop of intestine is dealt with in a similar manner, and the sections of the button are then clasped together. The peritoneal surfaces unite, and by the constant pressure exerted by the spring of the button the compressed parts slough, allowing the button to pass per anmti in ten or twelve days. The operation has a wide application, and can be used for lateral anastomosis, end- to-end anastomosis, gastro-enterostomy, enterectomy, pylorectomy, and cholecystenterostomy. Jessett has devised an operation which may prove useful from its simplicity. He makes a longitudinal opening into the intestine on the side farthest from the mesentery, directly over the intussusception, about one and a half inches long. Through this opening he exposes the invaginated portion, and with scissors cuts it off close to its origin (Figs. 113, 1 14, 1 15), and, seizing the distal part with volsellum forceps, draws it out of the intussuscepiens, ligating any vessels that bleed. The cut ends are next stitched together with a few interrupted sutures, the stump dropped back into the intestine, and the opening through which it was withdrawn closed with a double row of quilt sutures. The advantages claimed for this operation are that it is much less dangerous than resection or anastomosis, and that it is certainly preferable to an artificial anus. It may happen that the surgeon is so situated that he must operate without any of the artificial aids just mentioned, and some surgeons who are expert in the use of the needle prefer the old method. Abbe has described a procedure by simple incision and suture which in the hands of expert operators gives good results : I. The two portions of bowel which are to be united are placed side by side (Fig. 1 16). Fig. 116. — Suturing intestines in apposition FiG. 117.— Showing the four-inch incision and before incision (Abbe). the sewing of the edges (Abbe). 2. Two rows of continuous Lembert sutures a quarter of an inch apart and an inch longer than the necessary incision are applied as in Fig. 117, and each thread left with its needle at the end of the line of suture. 3. The bowel is opened parallel to and at a distance of a quarter of an inch from this line of sutures. The length of the incision is four inches, and both rows of sutures are at one side of the incision. Hemostatic forceps are applied to bleeding points and left there tem- porarily. The opposite portion of the intestine is similarly opened. 252 SURGICAL DIAGNOSIS AND TREATMENT. 4. The two adjacent cut edges are united by an overhand continuous suture, the mucous and serous coats being included. As this arrests the hemorrhage, the forceps can be removed as they are reached. The other free edges are similarly stitched. 5. The openings are now approximated and the two serous surfaces brought toeethcr. The needles left at the end of the first double suture are now used to apply a similar double line to the parts last approxi- mated, and thus the whole circumference of the four-inch opening is securely closed. Besides intussusception, intestinal anastomosis is indicated in — 1. Volvulus ; 2. In inoperable carcinoma if the disease is located high enough up in the colon to admit of an opening being made below it ; 3. Cicatricial stenosis of the intestine. Resection of Intestine {Enterectomy). — This operation is indicated in all cases w-here a portion of the bowel is gangrenous, or when the intestine is the seat of a malignant tumor and it is possible to remove the disease completely, or in the case of a benign tumor which cannot be removed by enterotomy. Any length of bowel from a few inches to three or four feet may be resected, but beyond this latter limit it is not safe to go, for in case of recovery the patient is almost sure to suffer from want of nutrition, and he gradually wastes away. Operation. — i. Draw the loop of intestine to be resected well out of the abdominal wound. At the upper and lower limits of the segment perforate the mesentery close to the bowel, and pass a piece of rubber tubing or strip of iodoform gauze through each opening, squeeze out the contents of the segment, and tie the tubes or gauze sufficiently tight to occlude the bowel. Place flat sponges or sterilized gauze pads beneath the segment, so as to protect the remaining abdominal contents. 2. Tie off the mesentery' in small sections with fine silk ligatures close to the intestine, divide the bowel with scissors or knife, making sure that you are cutting beyond diseased tissue. Wash out the lumen of each divided portion with warm sterilized water. 3. The divided ends are approximated in either of the following ways : (a) By lateral anastomosis, the ends being turned in and sutured, and the remaining steps as in Abbe's method. {B) End-to-end anastomosis. One continuous suture through mucous membrane only, and the serous coat stitched with Lembert's suture. For end-to-end anastomosis Murphy's button is very convenient and quickly applied, and, if the part resected is a portion of the colon and the large-sized button is employed, there cannot be any of the objections which are urged against its employment else- where. 4. The mesenter}' may be treated by excising a V-shaped portion or by folding the redundant portion upon itself and stitching it at its free edge. The after-treatment of resection consists merely in feeding the patient by rectal enemata for the first week. Nothing should be given INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 253 by the stomach except Hght liquid diet, and for the first twenty-four hours small pieces of ice. Volvulus. — The occurrence of a twist in the bowel is soon followed by great distention, peritonitis, and firm adhesions. If we remember that when the peritoneal surfaces are placed in close apposition there is thrown out, even by the end of the first hour, a thick coating of coagulable lymph, we can readily understand that adhesions soon become so firm that separation of them is out of the question. The bowel may be simply twisted upon itself or one coil may be intertwined with another. Strangulation in such cases quickly comes on, and gangrene is inevitable. Having exposed the volvulus, an attempt should be made to straighten out the twisted portion ; if this cannot be done, the distended bowel should be pulled out, opened above the con- striction, and emptied. A second attempt should then be made at reduction. If this fails, the safest procedure is to make an artificial anus. Resection is not advisable, as the extent of the volvulus is likely to include a considerable part of the intestine. The cases in which only a small portion of the intestine is involved are usually amenable to reduction. Strangulation by Bands. — As a rule, it is a simple matter to get rid of a band when once it is reached. A ligature should be placed at each extremity of the band as close to its attachment as possible and the band divided. One point should be guarded against, and that is the possibility of a second band. It has happened more than once that the successful removal of one band has not effected a cure, owing to the existence of a second band, which, unnoticed at the time of opera- tion, caused death by strangulation of the bowel at a later period. Meckel's diverticulum, a common cause of strangulation, must be dealt with in the same manner, care being taken not to mistake it for bowel, and using care in disinfecting the pervious ends when divided. When the diverticulum is pervious its mucous membrane should be turned inward and its fibrous coat stitched on the outside. After the obstruction has been relieved by any of the methods just described the remaining steps of the operation are conducted on the same principles as celiotomy for any purpose. The toilet of the peri- toneum requires due attention. The abdominal wound should be care- fully approximated, drainage employed when demanded, asepsis adhered to throughout, and the patient kept in bed long enough to allow a firm cicatrix, and thus guard against a subsequent ventral hernia. Chronic Intestinal Obstruction. — In this variety the intestine becomes gradually encroached upon and the lumen narrowed. At any time the occlusion may become complete, and then the case is practically one of acute obstruction. Chronic obstruction may be produced by — I. Stricture of the intestine, cicatricial or malignant. A cicatricial stricture is, in the majority of cases, the result of the healing of an ulcer in the wall of the intestine. Much depends upon the size of the ulcer and upon its shape. If the ulcerative process extends along the course of the gut, contraction is likely to be slight ; if, on the other hand, the ulcer is annular, the lumen is greatly lessened and may become entirely occluded. Strange as it may appear, the large bowel 254 SURGICAL DIAGNOSIS AND TREATMENT. is affected six times as frequently as the small intestine (Treves). When the small bowel is affected it is generally the middle and lower end of the ileum. Malignant stricture is almost always cancerous and of the cylindrical epithelial variety (cylindroma). It has a tendency to encircle the gut, and thus constriction is more readily produced. It rarely occurs in the small intestine. Of 43 cases tabulated by Jessett, the small intes- tine was the seat of the disease in only i instance, the rectum in 20, the sigmoid flexure in 10, and other parts of the colon in 12. This would indicate that the nearer the anus the greater the liability to malignant stricture. 2. Benign growths affecting the wall of the intestine may cause obstruction, but these are rare. They are such growths as adenomata, fibromata, myomata, fatty and cystic tumors. 3. Foreign bodies obstructing the lumen of the bowel. Among these are classed gall-stones, which may grow to sufficient size to cause obstruction, bodies swallow^ed and becoming aggregated, small polypi, and enteroliths. 4. Tumors outside of the intestine, but pressing upon the gut and obstructing its lumen. 5. Fecal accumulations. 6. Paresis of the intestinal wall. This form is found in connection with peritonitis following celiotomies. There is really no occlusion of the bowel, but the peristaltic action is completely arrested and ga.ses are retained, producing great abdominal distention and discomfort. Sometimes paresis results from reflex action, as in cases reported by Pitt and Jessett. 7. Adhesions following celiotomy or hysterectomy. One of the most annoying distant results of operations on the abdominal or pelvic organs is the occurrence of intestinal obstruction. If an abraded surface on the bowel comes in contact with the parietal wound or any serous surface, an adhesion is likely to take place at that point, which gives trouble sooner or later. Experience goes to show that this occurs more readily in suppurative cases. Two very^ practical points should therefore be borne in mind in abdominal opera- tions — namely, to spread the omentum out carefully over the intestine and to avert suppuration by the most scrupulous asepsis. These ob- structions sometimes prove fatal directly, or they may necessitate the opening of the abdominal cavity for their relief It is a statistical fact that these secondary operations are followed by a large proportion of fatal results. Diagnosis of Chronic Obstruction. — The symptoms of chronic ob- struction are the same as those of the acute form, only milder in degree. The history of the case will reveal some chronic intestinal disease, such as carcinoma, ulceration, or morbid growth. Repeated occurrences of obstructive .symptoms will be followed by periods of relief, but the tendency is for these attacks to return with increased frequency, and finally wind up with complete occlusion, when the symptoms will be intensified into the typical character of complete obstruction. Pain is not so marked a symptom as in the acute variety, in many cases coming on after eating. It occurs in paroxysms and has periods of INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 255 complete intermission. Vomiting appears later or not at all, and is rarely feculent. Constipation is usually present, but may alternate with attacks of diarrhea. Instead of the abdominal distention which is so marked a character of acute obstruction, we may have only attacks of flatulence, which, however distressing, may not cause dyspnea except when death is approaching. In the large intestine the most common form of obstruction is car- cinoma of the rectum. Its diagnosis is not difficult, but obstruction higher up may be obscure. The symptoms of obstruction in the large intestine as distinguished from the smaller bowel may be summed up as follows : Vomiting is less frequent, distention is more marked, and there is tenesmus with discharge of blood or pus. Diagnosis of Fecal Accumulations. — These occur in the large intes- tine only, and for obvious reasons the cecum and the sigmoid flexure of the colon are the two points at which obstruction most frequently takes place. In a case reported by Jessett the hypochondriac and right iliac regions were filled by a tumor which extended to the umbilicus, and, having the shape of the liver, was diagnosticated as carcinoma of that organ. The patients are for the most part women who have passed the active period of life, and lunatics. The history of a case of this kind is one of obstinate constipation, going on from bad to worse. In some cases there is diarrhea, which, paradoxical as it may appear, is often present when the bowel is obstructed by a mass of feces. The tumor is not only plainly to be felt, but may be visible. Its consistency is frequently an indication of its character. There is no other tumor in which a permanent indentation remains after pressure by the fingers. Treatment. — Purgatives are not only useless, but dangerous. If the accumulation is low down in the sigmoid flexure and filling the rectum, the masses can be broken up and removed with a scoop or the handle of a tablespoon. Repeated enemata of sweet oil, followed by copious injections of soap and water, give good results. Strychnin has a good effect in restoring the muscular contractility of the bowel and increasing peristalsis. To these measures may be added massage and the use of the faradic current. It must be remembered that a person who has once suffered from fecal accumulation is liable to a recurrence, hence every care should be taken to maintain the bowels in a healthy state. V. HERNIA. The protrusion of a viscus from its natural cavity through a dis- tended normal or an artificial opening is called a hernia. It includes not only abdominal protrusions, but also those occurring in the thorax, the cranial cavity, etc. In common parlance the term is applied to the escape of abdominal contents through the parietes, either at one of the natural openings, as the inguinal or femoral canals, or at weak points, such as the umbilicus or the thin cicatrix left after abdominal section. Clinically, we meet with hernia under various circumstances. One case may be strangulated and threatening to prove fatal in a few hours unless relieved ; another demands attention, owing to the inconvenience and pain produced by an ever-increasing tumor which cannot be kept within the abdomen. *' The life of a person afflicted with a hernia," says 256 SURGICAL DIAGNOSIS AiXD TREATMENT. Championnicre, " is generally a sad and painful one. He has to carry all his lifetime a truss more or less fitting, more or less adapted to his needs. He is incapable of vigorous exertion, and the intestines, pass- ing in and out of the hernial sac, give rise to colic more or less severe. Sometimes the hernia is never reduced completely, and the patient is always threatened with strangulation. " Besides these inherent defects accompanying a hernia, it is demon- strated that the sufferers are subject to a peculiar lack of vitality, especially in those afflicted with hernial of large size or of long standing. The majority of these cases are troubled with diabetes or albuminuria. Hernia thus leads to an inevitable cachexia of which albuminuria and diabetes are very grave results." The diagnosis of hernia seldom presents great difficulty, but the most serious consequences frequently arise from failure to recognize this condition. A young physician is called to attend a man who is suffering intense abdominal pain. He makes a hasty examination, employs a hypodermic of morphia and hot fomentations, with assurance that the disease is only colic and that the patient will be all right next day. For three days the condition grows steadily worse ; vomiting sets in and becomes feculent. Another physician is called, who, recognizing a strangulated hernia, sends the man to a hospital. An operation is performed at midnight, but the patient dies upon the operating-table. There are few surgeons of large hospital experience who have not seen cases with this unfortunate history. In severe abdominal pain or vomiting an examination for strangulated hernia shoidd never be neglected. The causes of hernia are predisposing and exciting. Certain parts of the abdominal wall are naturally weaker than others, as the inguinal ring, the femoral ring, and the umbilicus. Certain abnormalities tend to hernia, as late descent of the testes, patulousness of the inguinal canal, patency of the tunica vaginalis, lengthening of the mesentery, and separation of the recti muscles. Among acquired defects may be mentioned abdominal operations, in which the tissues have not been brought into perfect apposition or where undue tension or suppuration has prevented the formation of a firm cicatrix. Repeated pregnancies and distention of the abdomen by ascites and sudden emaciation are also predisposing causes. The immediate or exciting causes are chiefly the action of the abdominal muscles. Consequently, those persons who engage in laborious occupations and frequently make strong muscular efforts are most liable to hernia, and especially if there is a predisposi- tion. Violent efforts in coughing, straining at stool, and in urination are also exciting causes. A long mesentery favors the descent of a hernia in adult life. The congenital variety occurs more frequently on the right side than on the left, owing to the fact that the root of the mesentery lies lower on that side. All perversions of function or diseases of the intestinal tract which cause relaxation of the mesentery favor descent of a hernia. Prolapse of the mesentery has been considered very important. It occurs during late adult life, and is accompanied by a characteristic and readily recognized bulging of the lower part of the abdomen. The epigastric region is depressed, while below there is a bulging both at the sides and in the median line, where the muscles are the weakest, INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 257 and a radical cure which is attempted for the purpose of rendering the abdominal parietes more firm and resistant must of necessity fail, for the reason that the root of the mesentery has been weakened from some cause and has slipped down. Certain hereditary conditions no doubt predispose to hernia. The inguinal forms occur more frequently in men than in women, while the femoral and umbilical are more common in the latter. Varieties. — Hernia is classified according to the position which it occupies — viz. inguinal, femoral or crural, umbilical, ventral, diaphrag- matic, etc. Of these the inguinal is by far the most common, occur- ring in 80 per cent, of all cases. Classified according to the manner in which the sac is formed, herniae are divided into two classes — congenital and acquired. The contents of a hernial tumor are made up of — (i) a sac, which is always the peritoneum, except in the very rare cases where a portion of bowel uncovered by peritoneum escapes ; (2) a loop of intestine, generally the ileum ; (3) omentum. The character of the contents is expressed by using the Greek name of the viscus and the termination cele {rqXrj, a tumor) ; thus we have enterocele when the tumor contains intestine ; epiplocele when the oment?im occupies the sac ; entero- epipiocele when the sac contains both intestine and omentum. In addition to the foregoing, it is common to find in any hernial sac a small quantity of serous fluid. From a clinical standpoint every hernia falls into one of three classes : Reducible, when the contents of the sac can be returned to the abdominal cavity by simple manipulation ; irreducible, when, owing to the formation of firm adhesions, reduction cannot be accom- plished ; and strangulated, when constriction at the neck of the hernia not only prevents the passage of the intestinal contents at that point, but obstructs the circulation in the bowel-wall and speedily leads to gangrene. Symptoms. — Four-fifths of all cases of hernia occur in males. The patient, as a rule, only consults a surgeon after he or his friends have recognized the existence of a tumor in the groin, scrotum, or elsewhere. There are many cases in which the patient is unaware of the nature of his infirmity, and yet there are certain warnings which should arouse the surgeon's suspicion. These are — 1. A feeling of weakness at a certain point, relieved by the support of the hand or on assuming the recumbent posture. 2. Colicky pain and griping, supposed to be due to dragging on the mesentery. This is more noticeable on exertion and after eating. 3. During sudden efforts, in which the abdominal muscles are brought into violent contraction, the patient feels that something has given way. 4. Mo.st important of all is the agonizing pain which is characteristic of strangulation. It is generally felt at the umbilicus, and patients describe it as twisting in character. The Tumor. — Drawn to make a local examination by one or more of these warnings, a tumor will be found, the character of which depends upon its contents. If composed of intestine, the surface is smooth and elastic, and if large enough for percussion it is resonant. Place your 17 258 SURGICAL DIAGNOSIS AND TREATMENT. fingers upon it and ask the patient to cough— a distinct impulse is felt. This impulse on coughing may be regarded as the pathognomonic sign of hernia, and an examination without looking for it is no examination at all. The patient should be examined while he is standing up, as well as while he is lying down. If he stands upon a chair, it is still better, as the hernia can be examined at the level of the surgeon's hand. This is a very favorable position for the determination of multiple herniae (Championniere). When omentum constitutes the bulk of the tumor the impulse is not so expansile; the tumor is hard, doughy, and uneven. An enterocele slips back quickly when reduced, and there is a peculiar gurgle which is a welcome sound to the surgeon's ear. Epiplocele, on the other hand, goes back slowly, and, containing no gas, there is of course no gurgle. Having settled the point that the tumor is a hernia, the next ques- tion is whether it is above or below Poupart's ligament. If above, it is an inguinal hernia ; if below, it is a femoral hernia. The spine of the pubis is an important landmark. An inguinal hernia always protrudes at the external ring just at the spine, and lies above Poupart's ligament. A femoral hernia is always below the spine. Inguinal hernia occurs as a tumor near the center of Poupart's ligament. There are two varieties — viz. oblique or external, direct or internal. In the indirect hernia the bowel escapes from the abdominal cavity at the internal abdominal ring, pushing the peritoneum before it, and, following the inguinal canal, emerges at the external ring. Along this same route the testicle, on the way to the scrotum, has been the pioneer, and the intestine may follow it the entire distance. The epi- gastric vessels lie to the inside of the neck of the tumor. In the direct form the bowel does not enter the internal ring or traverse the inguinal canal, but, pushing the fascia before it, escapes directly through the external ring. In examining the tumor these two forms can generally be differ- entiated. The indirect form is by far the more common ; the tumor is oval in shape or, when it has descended to the scrotum, it is pyriform. The history of the case will show that the tumor began to appear at the middle of Poupart's ligament and gradually extended toward the pubes. The pulsation in the epigastric vessels is usually obscured. The size of the tumor is sometimes immense, in some cases filling the scrotum and causing it to drag downward until it comes almost to the knee. The indirect hernia usually contains intestine. It is reduced by pressure outward and backw^ard. Direct inguinal hernia is rare. The tumor is small and globular, usually making its appearance a little to the inside of the middle of Poupart's ligament. It generally contains omentum, and the epigastric vessels lie to the outer side. It is reduced by pressure directly back- ward. The finger-tips can be pushed through the canal directly into the abdominal cavity. On the inner side of the opening can be felt the conjoined tendon and the posterior upper surface of the pubis ; on the outer side is the epigastric artery. When a hernia is large and of long standing, the differential diagnosis may be impossible, for the in- ternal may be dragged downward until it is opposite to the external ring. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 259 Femoral hernia is a female hernia ; that is to say, it is much more frequently met with in women than in men. Its position is in the crural canal, which has the following anatomical boundaries : In front, Poupart's ligament, the deep crural arch, and the falciform edge of the fascia lata ; on the outer side, the femoral vein ; on the inner side, Gim- bernat's ligament ; and behind, the bone. The anatomical landmark for this hernia is the spine of the pubes. A femoral hernia is always below it and to the outer side. In hernia of long standing and of considerable size it may be diffi- cult to say whether the tumor is above or below Poupart's ligament, for as it enlarges it turns upward and toward the abdomen, giving the appearance of an inguinal hernia. What adds to the difficulty is the existence in some women of a fold of the groin which extends across the thigh lower down than Poupart's ligament, and may be mistaken for it. When a femoral hernia remains in the crural arch it is said to be incomplete ; when it protrudes at the saphenous opening it is called complete. Diagnosis between hernia and other swellings of the inguinal or femoral region : Bubo is generally associated with chancroids, gonorrhea, and syphilis, and there are redness of the skin and tenderness. If the swelling and subcutaneous infiltration are not too great, the outline of the inflamed gland can be felt. Chronic inflammation of a gland in the groin seldom leads to confusion, as the glands are distinct and movable. Glands enlarged by malignant disease are hard and frequently occur in chains. Undescended testicle has the characteristic pain on pressure pecu- liar to these organs, and, besides, there is absence of the testis in the scrotum. Varicocele is a swelling resembling a bunch of worms, commencing in the lower portion of the cord and increasing upward. There is no impulse on coughing. The swelling may disappear when the patient lies down, as is sometimes the case in hernia. If the part be supported and the patient stand up, the swelling will return in the case of varico- cele, but not so if the case be one of hernia. Hydrocele is translucent, and the swelling begins at the lowest part of the scrotum, while in hernia this is the ultima thule. Hydrocele of the cord is never very large, and has but a slight impulse on coughing. The swelling moves with the cord. Abscess in the neighborhood of Poupart's ligament may assume the shape of a hernial tumor, but there are the characteristics symp- toms of suppuration, pain, high temperature, etc. Psoas abscess has a history of spinal or pelvic disease ; the tumor, if superficial, fluctuates and gradually disappears under pressure. Irreducible Hernia. — When, without impairment of the circula- tion or the passage of feces, a hernia cannot be returned into the abdomen, it is said to be irreducible. This may be brought about by a variety of causes : the hernia may be composed of omentum, which takes a mushroom shape, a small neck and an expanded body ; a large quantity of fluid in the sac may interfere with direct manipulation of the bowel ; or the great size of the tumor may in itself be an obstacle 260 SURGICAL DIAGNOSIS AND TREATMENT. to reduction. The most frequent cause, however, is the existence of adhesions, either between the sac and its contents or between the con- tents themselves. Irreducible hernial are the cause of great discomfort. More and more of the intestine slips down into the sac until the tumor reaches an enormous size. Continual dragging pain, dyspepsia, colic, and the ever-present danger of strangulation make the patient's lot anything but pleasant. Incarcerated or Obstructed Hernia. — When, without any inter- ference with circulation, the loop of bowel contained in a hernia becomes impacted with feces and gases, the hernia is said to be incar- cerated or obstructed. This only happens when the colon goes to form the hernia, as the contents of the small intestine are always liquid. This condition is most frequently met with in umbilical hernia, especially in that form which afflicts women who have borne many children. It is easy of recognition. The tumor is hard and uneven, and in some cases tympanitic. It hangs down from the umbilicus, and usually attains con- siderable size, attended with colic, nausea, and total constipation after the lower bowel has been emptied. Strangulated Hernia. — A strangulated hernia is one in which constriction at the neck is so complete as to arrest the circulation, paralyze the nerves, and stop the flow of contents through the bowel. Such a condition is naturally attended with the utmost danger, and its progress is rapid — from strangulation to gangrene is a short step. It is not essential that the hernia should contain intestine, for when the sac contains omentum, or, in fact, any other structure, the course and symptoms are the same. When the bowel is involved it may be con- stricted at one side or in its whole circumference. In either case per- foration is the usual consequence, the contents of the bowel escaping in some instances into the peritoneal cavity, setting up general peri- tonitis. In others they are poured out into the sac and followed by suppuration. Svviptoins. — If once the existence of hernia be recognized and the symptoms of strangulation superadded, error in diagnosis is impossible, The danger of making a false diagnosis lies in the fact that the con- dition may be regarded as due to gastritis when vomiting is an early and prominent symptom, or to peritonitis when pain and abdominal tenderness are most marked. Two classes of symptoms must be recognized — one due to obstniction of the bowel, the other to strangula- tion. In every case of severe abdominal pain or persistent vomiting the question of hernia should be considered, and every probable site of hernia should be carefully examined. Pain is usually an early and prominent symptom. It is generally referred to one spot, the seat of the hernia, but frequently, and espe- cially at a later stage, it is felt at the umbilicus, and described as if the intestines were being violently twisted at that point. Tenderness is most marked at the seat of hernia, but is commonly a marked symp- tom over the whole abdomen. W^hen gangrene has become complete pain ceases, and its sudden cessation may be regarded as a harbinger of death. Too much reliance should not be placed upon pain as a symptom. In some cases it is almost absent, and in others its onset is delayed. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 26 1 Vomiting may come on at the very commencement of strangulation, or it may appear at a much later period. The higher the strangulation in the bowel, the earlier, as a rule, will vomiting set in. At first the food newly received into the stomach is ejected undigested and unal- tered. After a time the gastric secretions, still later the chyle and bile, are ejected, and lastly the vomit assumes all the characteristics of fecal matter. Obstruction is manifested by constipation, which is persistent and complete. After the bowel below the strangulation has been emptied nothing more, not even flatus, comes away. The abdomen gradually becomes distended and tympanitic, but the area of liver-dulness remains intact, thus showing that the gas is in the intestine and not in the peri- toneal cavity. The part of the intestinal canal implicated may be approximately determined. If, after the onset of the symptoms, a considerable evacuation takes place from the bowels, it may be con- cluded that the obstruction is in the small intestine. Distention also comes on slowly if the lower intestine be the strangulated part. The tcvipcraturc is seldom above normal, and in the late stages it becomes subnormal. The pulse is generally rapid, and becomes feeble and intermittent toward the close. Examination of the hernial tumor will reveal tenderness at the seat of strangulation. There is absence of impulse on coughing. The later history of a case of strangulation is the history of gangrene. If we were restricted to the use of two words in describing the course of a strangulated hernia, we would not be far astray if we used peritonitis and gangrene. The first acute onset with its violent pain and other signs of peritonitis passes into a stage in which the constitutional symptoms play a more prominent part. More and more offensive becomes the vomited matter, and it comes in great gushes without any effort ; the pulse becomes feeble and intermittent ; hiccough is con- stant and distressing ; the abdomen becomes more and more distended ; the face is haggard ; the mind wanders ; the surface of the body becomes cold and clammy ; and death by exhaustion ends the fearful scene. In rare cases nature brings relief and prevents a fatal termination. The tumor is swollen and edematous, and even tympanitic from the putrefying gases ; the skin ulcerates and the contents escape, leaving the patient his life, but with it the misery of an artificial anus. When the hernia contains omentum only, or when only a part of the circumference of the bowel is strangulated (Littre's hernia), the symptoms are the same, only in a less marked degree. Differential diagnosis of strangulated hernia must rest between hernia and — 1. Acute peritonitis. The existence of a hernia previous to the onset of symptoms and the presence of a tumor must be mainly relied upon to exclude peritonitis. 2. Inflamed or obstructed irreducible hernia. The pain, constipa- tion, and collapse are never so marked as in strangulation. The vomiting is not fecal. Treatment of Strangulated Hernia. — A condition so grave and violent in its progress demands the most prompt and decisive treat- 262 SURGICAL DIAGNOSIS AND TREATMENT. mcnt. Strangulation must be relieved or death will most certainly result. Two measures are relied upon — taxis and operation. In employing taxis or manipulation the first point demanding attention is to secure complete relaxation of the parts. The head should be lowered and the pelvis raised. If the hernia be inguinal, flex and adduct the thigh ; if femoral, flex and rotate inward. Steady the neck of the sac with the left hand while the right gently manipulates the tumor with the view of emptying it of part of its contents. If intestine slips back, a welcome gurgle announces the fact ; omentum goes back more slowly, but with an equal sense of relief Should gentle efforts at reduction fail, more complete relaxation of the parts must be secured by putting the patient under chloroform. But before doing so every prep- aration should be made for an operation in the event of taxis proving a failure. This is required for two reasons — first, because the patient should be subjected to anesthesia only once ; and second, because the case, if unrelieved by taxis, will not admit of a moment's delay. The operation for strangulated hernia or herniotomy consists in cut- ting down upon the constriction, dividing it, and returning the bowel to the abdominal cavity, or otherwise dealing with it as circumstances demand. The pubes, scrotum, and neighboring parts having been shaved and thoroughly disinfected, an incision is made in the long axis of the tumor, the center of the incision corresponding with the position of the neck of the sac. The next point is to find the sac, which, to an inexperienced operator, may be a little difficult. It is recognized by the fat which usually covers it ; grasped by the finger and thumb, its surfaces can be made to slip over each other. Carefully dissecting down through the tissues, we know that we have entered the sac by the escape of a yellow or dark-brown fluid. Through the puncture in the sac a groov^ed director is passed, and an opening made sufficient to admit the finger, upon which the sac is divided to the full extent of the tumor. The finger is now passed up to the constriction, palmar surface upward, and the nail slipped into the opening. A long probe- pointed bistoury is passed up, the flat surface of the instrument against the palmar surface of the finger, until it slips between the sharp edge of the constriction and the nail. The edge is now turned upward and the ring sufficiently divided to relieve the strangulation. The contents of the hernia should now be carefully examined, and especially the bowel. Warm sterilized gauze is applied to the wound, and allowed to remain for several minutes in the hope that circulation may be re-established in the strangulated tissues. A strangulated intestine varies in color from a pinkish gray to black ; if in the course of five to fifteen minutes it changes to a healthy red, circulation is restored and the bowel can be returned to the abdomen. The sac is then treated in the same manner as in the radical operation for hernia,, and the operation completed as described under the radical operation. When omentum is contained in the sac, it should be separated if adherent, tied in sections, and cut off Should the intestine prove to be gangrenous, it may be dealt with by one of three methods: i. The gangrenous portion is exsected ; the healthy divided ends are brought together by end-to-end anastomosis (enterectomy). 2. An artificial anus is formed by suturing the bowel INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 263 to the edge of the wound and opening into its lumen. 3. The bowel is returned to the abdominal cavity, stitching it to the abdominal wall inside the ring, and placing a drainage-tube in contact with it. This is only applicable when the portion of gangrenous bowel is small. The Radical Cure of Hernia.' — In the case of strangulated hernia " the radical cure " is a term applied to a method of treating the sac and closing the canal which prevents recurrence of the hernia. Its usefulness is, however, by no means limited to strangulated hernia, for it is almost universally adapted to those unfortunates who are doomed to carry a truss through life, who are constantly threatened with the dangers which are for ever hanging over the heads of the ruptured, or who are shut out from many of the active walks of life by these inflictions. Long is the history which deals with the various attempts at the radical treatment of hernia. Some were subcutaneous, as Wood's and Spanton's, but the advance of aseptic surgery has proven that not only greater accuracy, but equal safety, is gained by operations which lay the parts open to view and deal with the separate structures as their condition demands. The operation is imperative in — (i) strangulated hernia; (2) in herniae whose volume is gradually increasing. The operation is indicated in (i) irreducible herniae ; (2) congenital herniae with ectopic testicles ; (3) painful herniae ; (4) herniae in subjects afflicted with diseases that form dangerous complications, as spasmodic asthma, chronic cough, etc. ; (5) social necessities may demand the ope- ration, as in those who have to perform manual labor, those who wish to enter the military service, etc. The operation is contraindicated in — (i) old men and very young children (under six years of age) ; (2) persons who have albuminuria, diabetes, or tuberculosis : those afflicted with emphysema are the most dangerous of all ; (3) those predisposed to hernia. If we bear in mind the conditions essential to the existence of a hernia, the indications of treatment will be better understood. 1. In every hernia there is an enlarged foramen or canal in the abdominal wall (Fig. 118). 2. Protruding through this opening is a serous sac which forms an inclined plane, smooth and slippery, on which the viscera glide. 3. The viscera which form the hernia are generally the intestines and the omentum. Everything tends to place the intestines upon this slip- pery surface. Ordinarily the intestine is loose on this inclined plane, but sometimes it forms adhesions with the omentum, which goes down with it. In view of the principles just laid down we have three indications which must be fulfilled as much as possible : I. The serous membrane must be modified or destroyed, for the destruction of the slippery surface will remove the tendency of the intestines to slide over it. The opening of the sac, and then its removal at the highest possible point, will destroy the slippery inclined plane. In order that this de- 1 For much that follows I am indebted to the excellent work of Champion niere, Ctire radicale des Hernies, Rouff, Paris. 264 SURGICAL DIAGNOSIS AND TREATMENT. struction be complete, the serous membrane away above the neck of the sac must be removed with it and the oi)ening closed by a strong liga- ture, so that no cul-de-sac or infundibulum be apparent, and that in the Fig. 118. — Schema of the constituents of a hernia; sac and slippery surface traversing the wall (Championniere).

We must build up at the opening in the abdominal wall a most resisting cicatrix as a powerful barrier to prevent the forcing out of the Fig. 120. — Serous sac of a hernia with the points {A and B) at which the de- struction of the serous sac must take place (Championniere). Fig. 121. — Sac drawn down by traction and dissection ; the points A and B have descended to A' and B' (Championniere). viscera which have a tendency to come down. This point is gained by the close approximation of a large operation-wound. The extensive dissection of the serous membrane is an important preparatory step, INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 265 and it may be said that the larger the incision the more powerful will be the cicatrix. 3. If intervention with the contents of the sac be possible, we must destroy the parts not essential to the functions of the abdomen — e. g. the omentum. The omental mass contained in the sac should not only be removed, but all that can be drawn down by strong effort. This is all cut off, thus creating in the abdomen a corresponding vacuum (Figs. 120 and 121). In this way the omentum cannot play its customary part in producing a recurrence of the hernia (Fig. 122).

After resection the pedicle O, by retraction of the peritoneum, ascends to O' (Championniere). Fig. 123. — Sac closed by chain ligatures (Championniere). Championniere' s Operatioji. — First Step : Removal of the Sac. — The incision should be made where it best exposes the neck of the sac ; it should not be too short, for the operator needs an abundance of room to make a complete dissection of the sac ; it should be as far away as possible from the scrotum and penis, and especially from the labia, to guard against infection from the secretions of these parts. The sac, par- ticularly if small, is often difficult to find; hence the advantage of mak- ing the incision as high as possible in the direction of the inguinal canal. No matter how thin the sac may be, an attempt should be made to dissect it out /;/ toto. A pair of blunt-pointed scissors is the best instru- ment. The sac must not be too strongly drawn upon, for it will either be too firmly adherent to be separated from the other tissues, or it will be too thin to stand the strain and will tear. Whatever the hernia operated upon, the layers must be separated one by one, and the serous membrane isolated as much as possible from the neighboring parts, in order to carry dissection as far up as possible. In an acquired hernia the adhesions may be just as firm as those of a congenital hernia. In the latter variety the sac is generally very thin. Having reached the highest point, a strong ligature is applied and the sac cut off When the sac is large it should be tied off with a chain ligature, as seen in Fig. 123. Second Step : Treatment of the Orgaiis contained in the Hernia. — The intestine, if healthy, is returned to the abdomen, and requires no further 266 SURGICAL DIAGNOSIS AND TREATMENT. consideration. The omentum is a structure requirinj^f the most careful manat^^ement. It is a dreaded agent in the formation, maintenance, and recurrence of hernia, and should be reduced to the smallest possible dimensions. Not only should the protruding omentum be removed, but all that can be drawn out. And when none presents at the open- ing, the finger should be passed up in search of it with a view of draw- ing it down and resecting all that can be pulled out. The removal of omentum has three advantages : 1. It empties the abdomen of part of its contents and makes room for other viscera. 2. It suppresses an organ which is an active agency in the formation of hernia. 3. This procedure allows us to discover adhesions at or above the neck of the sac whenever they exist. These adhesions are often the cause of the return of the hernia and the persistence of pain. Having broken up adhesions and brought down the omentum, it should be laid upon a sterilized towel and spread out until it is in a single layer, with every vessel of any size plainly visible. De Garmo urges the importance of numerous ligatures, instead of the older method of tying off in one or two masses. He begins at one edge of the fan-shaped omentum as it is spread out in a single layer, and places a row of silk ligatures across to a corresponding point on the opposite side. No piece of fat larger than a lead pencil is included within one ligature, and every vessel that can be seen is tied separately. The liga- tures are cut off close to the knots, except those at the edges, which are clamped with forceps to control the stump. The omentum is then cut away, the surface of the proximal portion is dusted with aristol, the end ligatures are cut off, and the stump dropped back into the abdomen.^ TJiird Step: CIosui'c of the IVoiDid to Secure a Firm Cicatrix. — The third fundamental condition of the radical cure is the formation of a strong barrier extending along the whole hernial region. To secure this the incision must be long and high up along the inguinal canal, without sparing the lax muscular fibers stretched by the passage of the viscera. One of the most potent factors in the formation of a strong cicatrix is asepsis, for the cicatrices w^hich are really strong, truly resisting, are those that heal by first intention. For the deep suturing the best material is kangaroo tendon. It is strong, easily tied, and is absorbed in about three months, the time generally required for the completion of cicatrization. The soft parts which formed the wall of the canal are first brought together, and when the hernia has been large one side of the canal should be made to overlap the other. This row of sutures should include the aponeu- rosis and muscles. The next row can be of catgut, and it unites the cellular tissue in front of the muscle and extends downward along the cord. The last row is made with silkworm gut and closes the wound in the skin. A drainage-tube is placed in the position farthest from infection, an antiseptic dressing applied, and strong and steady pressure maintained for three or four days. Treatment of the Testicle. — The testicle may occupy any of the following positions : ^ Annuls of Surgery, June, 1895. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 267 First : It may be in the bottom of the sac, as in congenital hernia. In this case it is normally located, and all we have to do is to provide from the hernial sac a serous membrane to cover it. The membrane may be sutured or it may be allowed to roll up around the testicle. Second : The testicle may be in the vicinity of the inguinal canal or in the canal itself This condition is more serious. If the patient is not young" and the testicle painful, it may be sacrificed, but most patients, even with atrophied testicles, object to this measure. The testicle and epididymis may be so firmly adherent to the hernial sac that it may be very difficult to separate them. The testicle held by fibrous bands is drawn upward, and held there in spite of our efforts to bring it down. If the bands be divdded, the testicle will remain down, but there is no lodgement for it. Championniere is in the habit of making a new bed for it by tearing through the cellular tissue of the scrotum with his finger. When the vas deferens is shortened and atrophied, the testicle should be sacrificed. In his 266 cases he has only been com- pelled to perform castration 5 times. Maceivcn's Operation. — The steps of Macewen's operation are as follows : (i) He forms a pad on the abdominal surface of the internal ring, and (2) closes the inguinal canal. (i) The formation of the pad. The bowel having been reduced in the ordinary way, the sac is thoroughly freed in its whole extent from the cord and from the walls of the inguinal canal. Then strip the peritoneum from the abdominal wall for about two inches round the internal ring and fix a stitch securely in the distal (/. e. the ab- dominal) extremity of the sac. This stitch is passed several times through the sac to its outer extremity, so that when drawn tightly the sac is Fig. 124. — Macewen's operation: the sac transfi.xed and drawn into a fold. Fig. 125. — The sac as a pad covering the abdominal aspect of the internal ring in Macewen's operation. Fig. 126. — Macewen's operation : the threads ready for tying. folded up Hke a concertina (Figs. 124, 125). The free end of the suture is then threaded on a hernia needle, passed along the inguinal 268 SURGICAL J) /A GNOSIS AND TREATMENT. caiKil and through tlic structures of the abdominal wall, from within outward, one inch above the ring. The skin is to be drawn up out of the way while this suture is being passed. The end of the suture is then fixed b\' introducing it several times through the external oblique muscle. In this way the sac is not only obliterated, but forms a pad which protects a weak point in the abdominal wall. (2) The closure of the inguinal canal is accomplished in the follow- ing manner (Fig. 126) : The conjoint tendon is penetrated in two places, at its upper and lower ends, by a single thread of catgut, so that a loop is made with its convexity on the abdominal aspect of the tendon. The lower freed end of this thread is passed from within outward through Poupart's ligament, and the upper end through the external oblique and transversalis muscles, each stitch maintaining the level it has at the conjoined tendon. The two free ends are then tied in a reef knot. The cord should be examined before tightening each stitch to avoid compression. The pad is now considered an objectionable feature, and mainly on this account Macewen's operation has been supplanted by the methods of Bassini and Halsted. BassinYs Operation. — First Step. — The incision extends from a point on a level with the anterior superior spinous process obliquely downward parallel to and about half an inch above Poupart's ligament, and ends at the center of the external abdominal ring. The dissection is continued until the aponeurosis of the external oblique is reached and exposed for a distance of about three inches. A director is then passed beneath the aponeurosis through the external ring, and the aponeurosis divided to a point half an inch or a little more above the internal ring. The edges of the aponeurosis are dissected backward toward the middle line as far as the edge of the rectus, and outward until the shelving portion of Poupart's ligament is fully exposed. Second Step. — The sac and cord are isolated by the fingers and blunt-pointed curved scissors. The cord and its vessel are separated from the sac and the separation carried high up within the internal ring. Third Step. — Open the sac, and, having separated adhesions and removed any thickened omentum that may be present, return the con- tents of the sac to the abdominal cavity. Ligate the sac above the internal ring and cut it off below the ligature. Fourth Step. — The cord is held up by a hook and the edges of the aponeurosis kept out of the way. Buried sutures are then placed so as to close the abdominal wall beneath the cord. These sutures, three to five in number, should include on the inner side the internal oblique and transversalis muscles, the transversalis fascia, and in some cases the edge of the rectus, on the outer side the shelving portion of Pou- part's ligament. Replace the cord and close the aponeurosis over it by a continuous suture. This suture should begin as near the pubes as possible without constricting the cord. The wound in the skin is closed by interrupted sutures. No drainage is necessary. Halsted's Operation. — In Halsted's operation for the radical cure of inguinal hernia an incision is made through the skin from a point 5 cm. above and external to the internal abdominal ring, as far as the INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 269 spine of the pubis. Then, the aponeurosis of the external obhque, the internal oblique, transversalis muscles, and transversalis fascia having been divided along a line extending from the external ring to a point 2 cm. above and external to the internal ring, the cord is isolated and reduced in size by excising all the veins except one or two. The sac of the hernia is next isolated and opened, and, its contents having been replaced in the abdomen, the peritoneal cavity is closed by a few fine silk mattress sutures, and the remainder of the sac cut off close to the sutures. The isolated cord is now raised on a hook (Fig. 127), whilst Fig. 127. — Inguinal canal laid open ; sac cut away after suture of the peritoneum ; elements of cord isolated and lifted up ; deep mattress sutures introduced : A, aponeurosis of the exter- nal oblique muscle ; D, vas deferens ; F, fascia transversalis ; P, peritoneum ; T, conjoined tendon; V, vein; Kf^, stumps of excised veins (Halsted). Fig. 128. — Deep sutures tied (Halsted). the cut edges of the incision through the aponeurosis of the external oblique, internal oblique, and transversalis muscles, and transversalis fascia are again brought together by six or eight deep mattress sutures. The cord passes between the two outermost sutures, and care must be taken that the distance between them is such that the cord is embraced without danger to its circulation. The cord will now lie on the surface of the external oblique muscle under the skin (Fig. 128). The skin- wound is closed by silver-wire sutures. Halsted's operation is sometimes spoken of as a modification of Bassini's, but this is not correct, as our famous American confrere not only arrived at his conclusions independently of the distinguished 2/0 SURGICAL DIAGNOSIS AND TR BAILMENT. Italian surgeon, but claims priority of publication. The two operations differ in several important particulars. In Bassini's method the cord is placed under the aponeurosis of the external oblique ; in Halsted's operation the cord is placed outside the aponeurosis. Bassini's ope- ration does not interfere with the veins of the cord ; Halsted removes all superfluous veins, thus diminishing the size of the cord — a very im- portant consideration. In Bassini's operation the obliquity of the inguinal canal is not restored ; it is restored by Halsted's method. The Radical Cure of Femoral Hernia. — The operation of Bassini of Padua is probably the best. He makes an incision parallel to Poupart's ligament and over the center of the tumor ; he ligates the sac high up and removes it. He unites Poupart's ligament with the pectineal fascia by three silk sutures which he inserts with a curved needle. The first is placed near the spine of the pubes, the second half a centimeter ex- ternally, and the third one centimeter from the femoral vein. These sutures are not tied until four other sutures are passed through the edges of the falciform fascia, and then the pectoneal fascia, the lower suture entering just above the saphenous vein ; the upper sutures draw Poupart's ligament backward to the pectoneal line and close the mouth of the canal. The other sutures bring together the anterior and posterior walls of the canal. The wound in the skin is then closed, and no drainage is employed. Palliative Treatment of Hernia. — As the radical operation comes nearer and nearer to perfection fewer cases will require treatment of a palliative kind. There are many persons whose natural abhorrence of a cutting operation will lead them to go through life with the annoy- ance of a hernia and the inconvenience of a truss. Besides, there are certain cases already stated which are not amenable to the radical cure, as old men and children below six years of age, persons suffering from albuminuria, diabetes, etc., and those who are predisposed to hernia. In young children a truss not only retains the hernia within the abdomen, but in many cases effects a permanent cure. Hence in them this treatment should always be adopted, with the radical cure held in reserve to be brought into requisition if the hernia remains after the child has reached the age of six years. Persons who are the subjects of hernia should avoid violent exer- cise, sudden strains, and should prevent constipation of the bowels. For retaining a hernia in the abdominal cavity a truss is necessary, and a great variety of appliances in this direction have been invented. For slight or incomplete hernia, or in persons who are not obliged to engage in laborious occupations, an elastic truss is sufficient, but in others trusses having a steel spring. and a pad composed of hard wood or rubber are essential. The wearing of a truss is attended with diffi- culty in the case of fat people, in a hernia which contains a portion of irreducible omentum, and in femoral hernia. In oblique inguinal hernia the pad is made to fit over the internal inguinal ring ; in direct inguinal hernia it fits over the external ring ; in femoral hernia over the femoral ring at the level of Gimbernat's ligament. Before applying a truss it is necessary to reduce the hernia. This is done by placing the patient upon his back with the pelvis elevated. The sac is first emptied as described in the employment of taxis. The INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 2/1 direction of pressure will vary according to the form of hernia. In indirect inguinal hernia this will be upward and inward. For the measurement of a truss a few points must be considered : the size of the aperture, the circumference of the pelvis one inch below the crest of the ilium, the circumference of the body below the level of the aperture, the distance of the hernial opening from the anterior supe- rior process, the direction in which pressure is to be applied, and whether the hernia is single or double. Umbilical Hernia. — This variety of hernia is found under three conditions : 1. Cong-enital. — Both male and female infants are found at birth to be the subjects of umbilical hernia, but female children are in the majority. The hernia is due to imperfect closure of the abdominal wall, the visceral plates failing to meet in the middle line. The cover- ing is often exceedingly thin, consisting only of the peritoneum and tissues of the cord, and allowing the contents of the sac to be plainly seen. These herniae are often of immense size, and may even contain all the abdominal organs. The cecum is a frequent constituent. The trcatmoit consists in reducing the hernia as soon as possible after birth, and retaining it by the use of strong strips of adhesive plaster over which a broad bandage is applied. In small herniae a small pad is useful under the strapping. The radical operation in mild cases is seldom necessary, as with proper care spontaneous cure is the rule. 2. Infantile umbilical hernia is the result of stretching of the cicatrix shortly after birth. The tumor is easily reduced, and can be kept in position by a pad about the size of a dollar and retained by an easy-fitting belt. Tight bandaging and conical or button-shaped pads which fill the opening are to be condemned. A piece of adhesive plaster which is brought across the hernia in such a way as to fold the skin up into a roll at each side of the umbilicus is often satisfactory. The tendency of this form of rupture is to get well as the child grows. 3. Umbilical hernia in adults is most frequently met with in females who have borne numerous children. The covering is generally peritoneum and skin, and the size of the tumor may be enormous. It may at first escape observation, and one of its first indications may be severe neuralgic pains radiating from the umbilicus. Two features characterize these hernise : they increase rapidly, and they readily form adhesions. In addition, the subjects are inclined to obesity and are liable to emphysema of the lungs ; consequently the cough and diffi- culty of respiration react upon the hernia, causing its more rapid increase in size (Championniere). Tj'catincnt. — Bandages here are of little value. The radical cure affords the best prospect of a satisfactory result. The operation is to be conducted on the general principles already laid down, consideration being given to differences in anatomical structure and physiological action. The incision may be straight or curved, the latter being chosen when it is desirable to lay open a larger space. One end of the incision must be over the hernial aperture. In view of the frequency of intes- tinal adhesions the sac must be cautiously opened and care taken to 272 SL'KGICAl. DUGiVOS/S AND TREATMENT. avoid perforating the bowel. \\\ dealing with the omentum the hernial opening should be freely enlarged and a free portion of the omentum found in the abdomen. From this point it must be traced down into the sac and freed from its adhesions. The omentum is drawn gently out, so that not onl)- the part which was adherent to the sac, but a por- tion that lay above the hernia, is drawn down, spread out upon steril- ized gauze, ligated off by chain ligatures, and removed (Championniere). The sac is next dealt with. It is freed from all adhesions, laid open, ligated by two, three, or more chain ligatures (as seen in Fig. 123), and cut off In closing the abdominal wound interrupted sutures of kanga- roo tendon are placed in the muscular wall. A continuous catgut suture closes the cellular tissue and fascia, and lastly a row of super- ficial and deep sutures, alternating, are employed to close the opening in the skin. Drainage is useful when the abdominal wall is very much thickened with fat, otherwise it is not indicated. Ventral Hernia. — A hernia in the linea alba, above or below, but not at, the umbilicus, in the linea semilunaris, or in any other part of the abdominal wall which is not a common position of rup- ture, is spoken of as ventral hernia. Many of the cases occur after laparotomies (Fig. 129). When of considerable size these herni?e are readily diagnosticated, and their treatment is practically that of umbilical hernia. The tumor may be very small and escape observation, and yet pro- duce very urgent symptoms. This is especially the case when the hernia contains omentum, which, forming adhesions, is retained in the sac. Sometimes the omen- tum forms a narrow band be- tween the stomach and the hernia. In such cases the pain and gastric disturbances are such as to lead to a suspicion of can- cer of the stomach. The band usually goes to the great curva- ture, and as a consequence intense suffering results from movements of the stomach or when the organ is distended with food or gas. The diagnosis must rest upon the presence of a tumor, however small, which may or may not be attended with an impulse on coughing. Sometimes the presence of a band may be determined by a drawing in of the abdominal wall at that point. Violent attacks of gastric pain and vomiting are also common consequences. Fig. 129. — Large vt-ntrnl hernia forming in the cicatrix made for removal of an ovarian cyst. The patient bore two children, after which a cyst formed in the remaining ovary, burst through the cicatrix, and filled the hernia (from a photograph in the collection of Dr. W. J. Mayo, Rochester, Minn.). INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 273 The treatment consists in the radical operation for the hernia and division of the omental band. lylimbar Hernia. — A weak point in females who have rapidly lost flesh is the triangle of Petit, formed by the lower margin of the external oblique, the latissimus dorsi, and the crest of the ilium. Its floor is formed by the internal oblique. The course of a hernia in this locality is through the lumbar fascia, near the outer edge of the quadratus lumborum muscle. Its interest from a diagnostic point of view lies in the danger of mistaking the hernia for tumor or abscess — an error which has more than once led to incision and disappointment. The history of the case, the occurrence of a reducible tumor in an emaciated female or its connection with a traumatism, the presence of an impulse on coughing, and the absence of symptoms of suppuration should make the diagnosis reasonably clear. The only treatment required, as a rule, is a comfortably fitting elastic abdominal belt. Other rare forms of hernia are the following : Obturator hernia, a very rare form. The subjects are generally above the age of fifty. It is seldom diagnosed during life unless it becomes strangulated. The symptoms resemble femoral hernia. The tumor is situated to the inner side of the femoral vessels in both forms. The most characteristic symptoms are pain along the course of the obturator nerve — that is to say, along the inner side of the thigh as far as the knee — and the presence of a hard and tender swelling on the inner side of the thigh, which in certain cases can be felt on vaginal examination. Treatment. — When there is strangulation, as is generally the case before the hernia is recognized, attempts at reduction by taxis should be made, which, if unsuccessful, should be followed by herniotomy. The constriction is at the obturator foramen. Perineal hernia is ver>^ rare, and is generally due to weakness of the levator ani muscle. The tumor is formed in front of the rectum, and in the case of females it may appear in the vagina or labium. The tumor is always reducible, which distinguishes it from cysts or other growths. Diaphragmatic hernia is generally the result of a severe trau- matism, as the passing of a cart-wheel over the abdomen or the wound of a spear or saber. The symptoms are those of internal strangulation, but in the majority of cases death occurs from the severity of the traumatism and a diagnosis can seldom be made. If under circumstances which would lead us to suspect rupture of the diaphragm we find tympanitic resonance in the precordial region, with interference with the heart's action, or over the pleura, with impaired respiration, a diagnosis of diaphragmatic hernia will probably prove to be correct. VI. APPENDICITIS. Arising from the lower and posterior part of the cecum is the appendix vermiformis, a rudimentary form of the elongated cecum of herbivorous animals. Its length varies from three to six inches, its diameter is about half an inch. Dr. C. J. Ringnell in 200 autopsies found the length to vary from two and a half to nine and three-quarter inches. 18 274 SURGICAL DIAGNOSIS AND TREATMENT. By a nicscntcry of its own it is bound loosely to the back of the cecum, in some cases to both cecum and ileum ; hence it is easily stretched or twisted when these portions of the intestines are distended (White). It is supplied by a sin<^le artery whose caliber is so small that stretching or twisting readily produces occlusion. The position of the appendix is not constant. 1. It is generally directed upward toward the termination of the duodenum, and lies to the inner side of the cecum. 2. It is directed downward to the inner side of the cecum and into the right iliac fossa. 3. It lies to the outside of the cecum, directed upward toward the right kidney. Much more rarely it is directed downward below the cecum, or it enters the sac of a hernia, or runs directly inward to form an attach- ment at the linea alba, as I once saw in the case of a young man who had suffered many recurrences of appendicitis. Inflammation in the appendix is a disease of common occurrence, and of late years has received a great deal of attention. The terms typhlitis, perityphlitis, paratyphlitis, and appendicular abscess have almost become obsolete, since a constantly accumulating mass of evidence goes to show that nearly all of the cases formerly classed under these names are due to inflammation of the appendix with or without suppuration. To say that there is no such thing as typhlitis without appendicitis is to disregard clinical facts. Lanphear operated on a case of supposed appendicitis, and found ulcer of the cecum with perforation and perityphlitic abscess. The appendix was normal.^ It would probably be correct to say that 98 per cent, of cases of peri- typhlitis are due to inflammation of the appendix. The appendix is composed of a serous peritoneal covering, a mus- cular coat, and a mucous lining with a large proportion of lymphoid tissue. To the presence of this lymphoid tissue is perhaps due the clinical fact that so many cases of appendicitis occur in childhood and youth. The starting-point of appendicitis is from within, commencing as a simple catarrh, and producing no local changes beyond a thickening of the mucous membrane, and perhaps an accumulation of mucus. From this point the disease may recede, pain, tenderness, and all other symptoms disappearing. These are the mild cases which are often pointed to as being successfully treated without operation. When the inflammation results in suppuration, abscess, and peritonitis, we have the disease presenting a variety of features, which will be spoken of presently (see Fig. 130). Causes. — I. The presence of a hard foreign body in the appendix, such as a fecal concretion, the small seeds of fruit, fragments of bone, etc. Although the presence of a foreign body is spoken of as the most frequent cause, it is not a common thing to find such a body in cases operated upon. Probably this cause has been over-estimated. 2. Catarrhal inflammation of the cecum and ascending colon. In this class of cases the inflammation spreads by continuity of tissue. As the mucous membrane becomes swollen the orifice becomes more 1 Ann. of Ufiiv. Med.

As this secretion always contains putrefactive and pathogenic organisms, the simple catarrhal inflammation readily becomes an infective one (Barling). Once suppuration begins, ulceration is a natural consequence. Ulceration soon leads to perforation, and perforation to peritonitis. Fortunately, against the effects of perforation Nature sets up her safe- guards. As the infective inflammation reaches the outer coverings of the appendix, adhesions begin to form, and the accumulating pus is enclosed within strong walls, which prevent the bursting of an abscess into the peritoneal cavity. Sometimes the adhesions occur so promptly that the perforation is sealed, and a return to health takes place without the formation of an abscess. In cases still more rare the inflammation spreads so rapidly that no barriers can be raised, and the consequence is a general peritonitis. Instead of ulceration of the appendix, the inflammatory action may result in gangrene. Pressure of the exudates on the v^essels from without and thrombosis from within can speedily cut off the blood-supply to the whole or a part of this functionless structure, which, at best, is endowed only with low vitality, and with its blood-supply cut off quickly becomes gangrenous. As predisposing causes typhoid fever and rheumatism have been mentioned. Age has a decided influence, and about 50 per cent, of all cases occur between the ages of ten and twenty-five. It is more common in males than females. Symptoms. — The leading symptoms around which many others group themselves are the following : 1. Severe localized abdominal pain, generally felt in the right iliac fossa, sometimes over the whole abdomen. 2. Tenderness over the position of the appendix midway between the umbilicus and the anterior superior spine of the ilium. We have seen that the length and position of the appendix are subject to vari- ations. It is only natural, therefore, that corresponding varieties should be observed in the location of the symptoms. For instance, in 3 cases reported by Fowler pain was more marked on the left side of the abdo- men, especially at the outer border of the left rectus. At the operation the appendix was found to the left of the rectus.' Too much reliance must not be placed upon the presence or absence of tenderness at McBurney's point, for there is no single point that can be definitely named as the position of the appendix, or, for that matter, of the cecum itself 3. A rise of temperature to 101° or 102° F. and a rapid pulse. This temperature is reached in the first twenty-four hours and seldom goes beyond. A temperature of 103° is very rare. 4. Nausea and vomiting. These four symptoms we expect to find in ev^ery case of appen- dicitis. Severe pain is present because there is inflammation in a structure whose walls are dense and resisting. By reflex action this pain is distributed widely over the abdomen through the sympathetic plexuses. This widespread pain continues for from one to twelve hours, after which it becomes localized in the right iliac fossa. ^ Ann. of Univ. Aled. Sd., c. 37, 1895. 2/6 SURGICAL DIAGNOSIS AND TREATMENT. Now comes tenderness on pressure over the appendix. There are the rapid pulse and high temperature peculiar to hectic fever, for suppuration is going on. Vomiting is present in most cases. It may- occur only once, and in any case it consists of the food last taken and of bile. Persistent vomiting or persistent hiccough is a very unfavor- able sign. The patient generally lies in the dorsal position, with the lower limbs extended, or the right may be drawn up to relieve tension in the iliac fossa. Where there is general peritonitis both limbs are drawn up and the abdominal walls are rigid. 5. Constipation is the rule, although diarrhea has been noted in a few instances. 6. In about two-thirds of the cases a tumor is found in the right iliac fossa. This does not necessarily prove the existence of an abscess. In some cases it is the thickened appendix, the omentum, and intestine matted together, or it may be the infiltration of the abdominal muscles and fascia. Care must be taken not to mistake rigidity of the muscles for a tumor. Anesthesia is a valuable aid in the examination, especially in children, in nervous subjects, and in those whose abdominal walls are thick. It is customary to mention palpation by the rectum as a means of detecting the presence of a tumor. I have never been able to derive any information from this method, and have long ceased to employ it. The cases in which such an examination proves of any service are prob- ably those in which the appendix takes a direction downward into the pelvis. Neither can we expect much help from palpation of the appendix itself, for, while it may be possible to detect it in the healthy subject, the extreme tenderness and swelling which attend appendicitis will render such a measure impossible during an acute attack. In relapsing cases it has proved valuable when employed during the interval between attacks ; and Ewald reports several cases in which palpitation enabled him to settle the diagnosis. The pressure must be deep enough to recognize the posterior abdominal wall and the brim of the pelvis against which the appendix is felt. The beginning of the appendix is found a little outside of a line drawn from the umbilicus to the middle of Poupart's ligament. 7. Movements of the bladder may produce pain, as in the act of micturition. Differential Diagnosis. — Of the diseases from which appendicitis must be distinguished I shall mention : 1. Pelvic inflammation in females. When a mistake is made, it is because the surgeon has neglected the imperative duty of making a vaginal examination. A diagnosis of appendicitis in a female should never be entertained until pelvic inflammation, especially of the ovaries and tubes, has been excluded. This, as a rule, is very simple : A fixed uterus, hardness and infiltration of the pelvic floor, or enlargement of tube or ovary leaves no room for doubt. 2. Intestinal obstruction. Appendicitis shows a rise of temperature from the beginning ; intestinal obstruction of any kind has a normal temperature until peritonitis has set in. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 277 3. Typhlitis from accumulation of feces occurs in patients well advanced in years ; there is a doughy, sausage-shaped tumor which retains an indentation made by the finger. The local tenderness is not so marked as in appendicitis. 4. Hepatic colic. The pain in hepatic colic is most intense at the position of the gall-bladder, and radiates to the shoulder and the angle of the scapula. In appendicitis the tenderness may at the outset be widely diffused, but in a day or two it becomes localized in the right iliac fossa. A history of repeated attacks, one or more of which have been attended with jaundice, is strong evidence of hepatic colic. Vom- iting is more persistent in the latter disease. 5. Renal calculus on the right side. Only when the examination of the urine is negative and the pain is not localized, or when the pain in appendicitis radiates toward the os pubis, scrotum, and testicles, with tenesmus and dysuria, should there be room for doubt. In such cases a little time will make the symptoms clearer, for the pain will become localized in the right iliac fossa, proving appendicitis, or tenderness will be manifested ov^er the kidney posteriorly, pointing to the kidney as the seat of the affection. Fowler gives the following diagnostic points in a tabular form : Appendicitis. Pain around the umbilicus and in the epigastric region, not radiating from these points ; fixed painful point in the iliac fossa. Greatest tenderness in the right iliac fossa, particu- larly at McBurney's point. Vomiting may be present, but is usually not continuous. The bladder and testicles are very rarely symptomatically tender or painful. Hepatic Colic. Pain in the epigastric region, radiating to shoulder and angle of scapula, arising from the gall-bladder as the fixed point. Great tenderness below the arch of the ribs ; slight ten- derness over gall-bladder. Vomiting frequent, and not to be suppressed. Bladder and testicles give no symptoms. Renal Colic. Pain radiating to inguinal re- gion and testicle, occasion- ally to the rectum when at stool ; also tenesmus. Greatest tenderness behind, over the pelvis of the kid- ney; in front the maximum point of tenderness is over Poupart's ligament. Vomiting is not a frequent nor prominent symptom. Bladder irritable ; dysuria and tenesmus of the bladder ; occasionally hematuria ; testicle retracted. All cases of appendicitis may be divided into four classes : First class, mild appendicitis, in which neither abscess nor perforation takes place. To this class probably belongs a majority of all cases. They are not regarded as surgical cases, and form the basis of the belief that appendicitis gets well without operation. The disease runs a mild course ; the pain, local tenderness, vomiting, nausea, and fever are not severe. The tumor, if present, is small, and all the .symptoms abate in three or four days. Second class, appendicitis attended with suppuration and the forma- tion of an abscess. This class belongs to the surgeon, and affords him support for the argument that the proper treatment for appendicitis is an operation. The pain is severe, the local tenderness is marked, there is fulness in the right lower quadrant of the abdomen, and sooner or later a tumor appears at the point of tenderness. There are special indications that suppuration is taking place. The temperature goes up to 101° or 102° or 103° F. at night, and has a 278 SURGICAL DIAGNOSIS AND TREATMENT. morning remission. In some cases there is a pronounced chill. If, after continuing several days, the temperature should go still higher, it is an indication that the septic infection is spreading to new localities. The pulse gives still more valuable information. If at the end of three or four days it continues to rise, reaching 110 or 120, the presump- tion of abscess is very strong. The tumor becomes more prominent, and, if allowed to take its course, redness of the skin, bogginess, and fluctuation may appear, leaving no doubt that an abscess has formed. Third class, perforating appendicitis presents some of the most per- plexing problems which can confront the surgeon. Its symptoms are often obscure, and, although operation is acknowledged to be the only treatment of any avail, the decision to operate will often tax the judg- ment of the most experienced. Much depends upon the position of the appendix. If it happens to lie to the inner side of the cecum, per- foration is speedily followed by symptoms that might be called explo- sive in their character — sudden, unremitting pain, tenderness, and tympanitic distention over the whole abdomen ; intense and persistent vomiting with a pulse running up to no or 120, and a temperature that suddenly bounds to 102° or 103°. When a case belonging to another class assumes this character, we may strongly suspect that perforation has taken place. When the appendix, by good fortune, lies to the outside of or behind the cecum or in a peritoneal pouch, adhesive inflammation plays an important part. As soon as a drop or two of the contents of the ap- pendix escape through a perforation the vicious fluid is fenced in by adhesions, and the danger of general infection is greatly lessened. Those who advocate operative treatment for every case of appendi- citis find in this class their strongest argument. No matter how mild a case may be at its outset, there always hangs over it three terrible risks — perforation^ rupture, and relapse. In the hands of a good ope- rator an incision which would reach the appendix is practically free from danger. On the other hand, perforation or rupture is almost certainly followed by death. Would it not be wisdom to anticipate these risks and choose the course which affords the best prospect of immediate cure and the only safeguard against recurrence ? The operation in perforating appendicitis is practically the same as in the suppurative form, except that when there is evidence of general infection of the peritoneum an incision in the middle Hne will give a better outlet. The fluid is often a milk-like serum rather than pus, and here irrigation is not open to the same objection as in other classes. Fourth class, relapsing appendicitis. The appendix, even after a mild attack, as well as the surrounding tissues, is more or less changed. Adhesions take place, the tube may become narrow at one or more places, or it may become kinked or twisted upon itself; all of which may lead to retention of its secretions and render it liable to future out- breaks of inflammation. The question of the most opportune time to operate in relapsing cases is a difficult one. Generally the patient set- tles the point by appealing to us only during an attack. This is probably the best time, but operations during intervals are, on the whole, satisfactory. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 2'jg Bull has collected 480 operations of this kind with 8 deaths, or a mortality of 1.77 per cent. He estimates that 5 or 6 per cent, would be more nearly correct.' Appendicitis obliterans has been described by Prof Senn as forming a class of cases in which the lumen of the appendix becomes gradually obliterated by relapsing disease. This classification seems unnecessary. In a functionless and rudimentary structure like the appendix oblitera- tion would, a priori, be a natural process. This assumption is borne out by the result of 400 autopsies made by Ribbert (death being due to other causes than appendicitis) in which partial or complete oblitera- tion was found in 25 per cent. Prognosis. — In a total of 364 cases Wyeth calculates the mortality of appendicitis at 18 per cent. The mortality from operations made in the interval between attacks is probably 5 or 6 per cent. (Bull). Treatment. — The treatment of the first class of cases is debatable ground. Granted that the majority of all cases are of this kind, and that they get well under medical care in three or four days, there is still the question of recurrence. An appendix which has been the subject of one attack is a perpetual menace. According to the statistics of Sahli, Hollander, Fiirbringer, Leyden, Reavers, Guttman, and Rotter, 90 to 91 per cent, of all cases of peri- typhlitis get well without an operation. On the other hand, many surgeons resort to operation as soon as they make a diagnosis, no matter how early in the disease or how mild the symptoms. Between these two extremes we must endeavor to find a golden mean. The operation in the hands of a skilful operator has a low mortality; but another consequence of surgical interference must be taken into account, and that is the risk of hernia. On the other hand, every case treated without operation has to run the risk of possible rupture during the attack and of relapse after the patient recovers. The third day, at the latest, should decide the question. If by that time the symptoms are abating, do not operate, but watch the case closely. If on the third day the case continues to grow worse or shows no signs of improvement, operate. In spite of every care there are cases in which grave doubts must exist as to the propriety of operation ; but, as Helfrich tersely expresses it, " It is always better to say, ' The patient might hav^e recovered without operation,' than to say, ' The patient might have been saved by operation.' " There are certain indications for operation which the most con- servative physicians will admit : First. When there is perforation followed by peritonitis. Many of these cases are the penalty of ultra- conservatism. Second. When there is evidence of a collection of pus. Third. When there are the current attacks increasing in frequency and severity. In the early stages of all classes of cases the first essential is perfect rest in bed. The horizontal position should be persistently maintained, the patient not being allowed to get up for micturition, defecation, or for any other cause. The diet should be easil}^ digested fluids. The practice of giving a purgative should be condemned. Fecal impac- tion in the cecum is not so common as was formerly supposed ; hence ' Ann. of Univ. Med. Sciences, 1895. 28o SURGICAL DIAGNOSIS AND TREATMENT. a purgative to remove impaction is unnecessary. The better course is to relieve the bowel by enemata without causing much distention. Warm fomentations locally afford great relief When, in spite of these measures, pain is very severe, the indication is not to give opium, but to operate. In the second class of cases (those attended with suppuration and abscess) the proper course is undoubtedly to operate. Wyeth states that in his entire experience he has yet to see a death which could not be properly ascribed to delay in timely and skilful surgical interference. The diagnosis of pus may be confidently made when the tumor begins to increase, the temperature showing morning remissions and the local tenderness persistent. Fluctuation and edema should not be waited for. The operation for appendicitis is performed as follows : An incision is made in an oblique direction through the skin, crossing a line drawn from the antero-iliac spine to the umbilicus, nearly at a right angle and one inch from the iliac spine (McBurney). This is in the direction of the fibers of the external oblique, which can be separated without cut- ting. The wound is now held open by retractors, and divisions of the internal oblique and transversalis effected in a similar manner along the direction of their fibers. The advantage of this mode of dividing the abdominal wall is that the action of the muscles tends to close rather than retract the edges of the wound ; hence the chances of subsequent hernia are greatly lessened. It is only suitable, however, in simple cases without suppuration. The position of the incision in suppurative cases must depend upon circumstances. It should be oblique and over the most prominent part of the tumor. Two inches in length is sufficient in most cases, though others will require three or four inches. Pus wells up as soon as the abscess is reached. The patient should be turned on to his right side, and the abscess-cavity mopped out with gauze. Irrigation should not be employed, le.st septic matter be carried into the general peritoneal cavity. Having evacuated the pus, the finger is passed into the wound, and search made for the appendix and for foreign bodies. The ana- tomical guide to the appendix is the anterior longitudinal band of muscle in the cecum which leads to the base of the appendix. When the appendix is found, it should be ligated near the cecum and removed. If it does not appear readily, no lengthened search should be made for it, as drainage of the abscess-cavity will be sufficient to dispose of all necrotic tissue, including the diseased appendix. The cavity should be drained from the bottom, either by strips of iodoform gauze or by a good-sized drainage-tube, around which gauze should be packed. The wound can be materially reduced in size by inserting a few silkworm- gut sutures, leaving sufficient room in the most convenient place for drainage. In the after-treatment of cases operated for appendicitis I would draw attention to two points : I. Fecal Fistula. — This is a complication which is likely to arise when the operation has been delayed till a large abscess has formed or when the drainage is not thorough. To the young or inexperienced ope- rator the escape of intestinal gases from the wound or the appearance of fecal matter therein is perfectly appalling. Experience, however, INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 28 1 has proved that such fistulae close of their own accord, and all that is needed is a little patience on the part of the surgeon and the afflicted one. 2. Deficient Drainage. — It may happen that after the operation the symptoms improve, and eveiything appears to point to a favorable issue, but at the end of a day or two the temperature rises, the pulse increases in frequenc}', pain returns, and the abdomen becomes tym- panitic. These symptoms indicate either the retention of pus or the formation of an abscess in a new location. The proper course to follow under such circumstances is to pass the finger into the opening and break up any adhesions that may have formed since the operation. You will generally find one or more pus-cavities. In one case of appendicitis I opened up the wound three times in this manner, and saved the patient's life. Sometimes nature comes to the patient's relief by allowing the concealed abscess-cav^ity to discharge into the bowel, and thence per viavi naturalcin. VII. DISEASES AND INJURIES OF THE PERITONEUM. The peritoneum is a serous membrane almost equal to the skin in its extent. While the skin is an organ which throws off waste material, the peritoneum absorbs the fluids with which it comes in contact, readily disposing of large quantities, and showing no discrimination between poisonous and benign substances. Hence septic or poisonous fluids are readily taken up and carried to the general circulation. The free movements of the membrane have also an important clinical bearing. It slides over the abdominal organs, and its own surfaces ghde smoothly over one another, so that an infection which at first is purely local is likely to become general in a short time. Another important characteristic of the peritoneum is the readiness with which it forms adhesions. Thanks to this power, septic foci are walled off and the success of many surgical operations is assured. So closely is the peritoneum associated with many of the abdominal organs that disease of these viscera is almost certain to extend to the serous membrane. Examination of the peritoneum is very satisfactorily conducted by inspection, palpation, and percussion.. In a systematic examination the following questions should be settled : I. Is the peritoneum distended? Two conditions can produce distention of the peritoneum — viz. escape of gas from the stomach or intestine and a collection of fluid — ascites. Escape of gas into the peritoneal cavity, technically named meteorismus peritonei, is always to be regarded as a very serious matter, and always leads to peritonitis. The abdomen is distended and tym- panitic, the pitch varying according to the degree of tension. This, however, can be said of tympanites from gas within the intestine. How, then, are we to decide the question as to whether the gas is con- tained in the intestine or free in the peritoneal cavity ? By percussion over the liver and spleen. If the gas be free in the peritoneal cavity, it will come in front of these solid organs, and there will be no liver or splenic dulness. If it is contained within the bowels, liver and splenic dulness will be present. The liver may be displaced upward by the 282 SURGICAL DIAGNOSIS AND TREATMENT. distended intestines, but it will nevertheless be recognized by dul- ness. When free fluid in the cavity is the cause of distention it gravitates to the most dependent parts. At the beginning it is confined to the peh-is (while the patient is standing), and gradually rises until it gives a dull area and produces bulging in the lower part of the abdomen. When the patient lies upon his back the fluid, gravitating to the most dependent parts, causes the sides to bulge outward, while the intestines and stomach float like air-balloons upon the water, and give a tym- panitic note in the anterior portion of the abdomen. Ask the patient to lie upon one side and then on the other, and in each case the fluid will settle to the lowest part, and give a dull percussion-note, while the intestines as promptly float and give a hollow sound. Fluctuation or undulation is another important feature of ascites. Place one hand flat upon the abdomen, and with the fingers of the other hand gently tap the abdominal wall at a distant point, and the waves of fluid can be felt and even seen. In people whose abdominal walls and omentum are loaded with fat there is a tremulous movement which may be mistaken for true fluctuation. When, owing to a large amount of fluid, there is much distention, it may be impossible to elicit fluctuation. If fluid be present, it is either free or encysted. When free the ease with which it gravitates to the dependent parts is very characteristic. When encysted there is a feeling as if a ball were grasped within the hand, or the tumor formed by the encysted fluid may have an elonga- ted form ; tension is usually greater, and consequently fluctuation is indistinct. Cystic ovaries, the pregnant uterus, and a distended bladder all rise in front of the abdomen, pushing the intestines back, and when the patient lies on the back the front yields a dull sound (Fagge). 2. Is the peritoneum inflamed ? Peritonitis, or inflammation of the peritoneum, is generally described as primary and secondary, but the opinion is gaining ground that most if not all cases are of secondary origin. That is to say, there are no cases of idiopathic peritonitis, there being an exciting cause in every instance, the recognition of which is essential to a rational line of treatment. The disease is also divided into acute and chronic varieties. Surgically, we are deeply interested in peritonitis on account of its frequency after many operations, such as celiotomy, lithotomy, lith- otrity, and litholapaxy. We also meet with it as an extension of disease or injury from the abdominal viscera. A perforation of the stomach or intestines with escape of contents is with certainty followed by general peritonitis. Septic infection can travel up the uterine canal and by way of the Fallopian tubes gain access to the peritoneum. A perforating appendicitis is responsible for many cases of peritonitis. Plastic Peritonitis. — A very interesting feature about the peri- toneum is its power to protect itself and other structures by throwing out plastic material which acts as a barrier to advancing disease or infection. This should not be classed as an inflammation, but rather as a regenerative process. Should the peritoneum be wounded or bruised or irritated by chemical substances, without the presence of septic infection, the result is generally purely local. The action of the peri- INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 283 toneum is at once changed, so that, instead of absorbing, it secretes, and its secretion is fibrinous material, which becomes organized and forms adhesions between portions of the peritoneum itself or serves to bind the membrane to neighboring organs. These adhesions may afterward be absorbed or they may remain as permanent structures. Examples of non-septic peritonitis are met with in aseptic wounds or other traumae of the peritoneum, the application of chemical irritants, the twisting of the pedicle of a tumor, the escape of aseptic contents of an ovarian tumor, and the strangulation of a hernia. This form of peritonitis being generally localized, the symptoms which manifest its presence are localized pain and tenderness, rigidity of the abdominal lua/l at that point, and the presence of more or less fever. The rise of temperature is due to resorption, the fermentative fever so commonly seen after operations, and in no way connected with suppuration. The symptoms appear in from six to thirty-six hours after the receipt of an injury. Collapse may at first mask the symptoms of peritonitis, but they become apparent when reaction sets in. The treatment of non-septic peritonitis consists in perfect rest in the recumbent posture, the use of hot fomentations and, if necessary, opiates. Septic Peritonitis. — Two things are necessary to produce septic peritonitis : first, the entrance of bacteria, and second, the peritoneum must have lost its absorptive power. The JiealtJiy peritoneum has a marvellous power of absorbing and disposing of bacteria, so that con- siderable numbers of germs can enter the peritoneal cavity without producing septic inflammation ; but let the membrane once lose its power of absorption, and infection readily takes place. The bacteria which are generally found in such infections are the pyogenic germs, but the common colon bacillus is so frequently present in cases of intestinal origin that some have thought it of diagnostic importance. Bacteria which produce peritonitis are sometimes spoken of as specific and non-specific. Of the specific germs, the tubercle bacillus occupies a most important position. The infection of syphilis seldom figures as a cause of peritonitis. Of the non-specific organisms, the pyogenic germs are most commonly found. Even they cannot produce peritonitis except when the amount of fluid which they con- tain is so great and the germs are produced so rapidly that the tissues cannot deal with them (Grawitz). This comes back to the second essential already stated, an inadequacy of the absorptive power of the peritoneum. The bacteria reach the peritoneal cavity, either directly through an opening in the abdominal wall, as in celiotomy, or from parts which are covered by peritoneum and communicate with the exterior of the body, as the intestinal canal and the genito-urinary tract ; or they may find their way upward through the open mouths of the Fallopian tubes, as is demonstrated in that terrible disease, puer- peral peritonitis ; or it is possible that they may come from remote points of the body, carried through one or more of the innumerable blood- or lymph-channels. The peritoneum may lose its power of absorption, and thus supply the second essential — {a) by being bruised or wounded, {b) by being the 284 SURGICAL DIAGNOSIS AND TREATMENT. seat of a pre-existing disease, or (r) by disease spreading from an organ to the peritoneum which covers that organ. Both of the essentials are well illustrated in perforation of the intestine ; numberless bacteria are admitted to the peritoneal cavity, and the rupture which lacerates the peritoneum deprives it of its absorptive power. Sy)npto})is. — Pain is the most prominent of all the evidences of peri- tonitis. In cases due to perforation of the stomach or intestine the patient may declare that the pain set in with a tearing sensation. It is nearly always sudden, and in most cases intense, cutting, or griping. The slightest motion aggravates it, and the unhappy sufferer guards against even such innocent movements as coughing or breathing, while vomiting is perfect torture. To guard against the slight motion of the abdominal muscles he draws his limbs up in bed, flexing the thighs upon the abdomen. So tender is he to pressure that the weight of his bed-clothes is unbearable, and the idea of examining his belly by manipulation fills his soul with horror. The fixation of his abdominal muscles causes him to resort entirely to thoracic respiration, and the chest rises and falls while the abdomen is perfectly still. The diaphragm cannot descend without producing pain ; consequently the breathing is rapid and shallow, reaching as high as forty, fifty, or even sixty, instead of eighteen or twenty, in the minute. It is scarcely necessary to press upon the abdominal wall to look for tenderness. If you need to do so, lay the hand gently upon the abdomen and watch the expression of the patient's face, which will indicate pain before he can express his sensa- tions in words. Sooner or later the abdomen begins to swell and becomes tympanitic ; hiccough is not uncommon ; quantities of dark- colored liquid are raised from the stomach without effort or, it may be, expelled by distressing vomiting. Pinched and anxious from the first, the face assumes a ghastly appearance ; the eyes become sunken ; the pulse becomes more and more feeble, and may be imperceptible at the wrist for twenty-four hours before the end. The condition of collapse supervenes and death closes the scene, the mind in many cases remain- ing clear until the last. When the body is examined after death little change is seen in the appearance of the peritoneum, and a small amount of serous fluid is all that is found in the cavity. But this fluid is intensely poisonous. Shun it as you would the venom of a rattlesnake. Such is the form of peri- tonitis seen in that awful disorder puerperal fever, and also after some abdominal operations. When fully developed, septic peritonitis is almost absolutely certain to prove fatal, and the most we can do is to palliate the patient's sufferings. In the universal rush to the operating-table these cases have not been made an exception, but, so far as my experience and observation have gone, abdominal section and unlimited flushings have proved of little avail. In the way of prevention, however, which is so much better than cure, there is everything to be hoped for. As accoucheurs form the habit of attending confinements with as strictly aseptic precautions as they would conduct a major operation, as nurses abandon filthy syringes and learn to hQ surgically clvau, septic peritonitis will gradually but surely disappear. After abdominal section it is not uncommon to find tympanites set- INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 285 ting in, which may possibly be the beginning of septic peritonitis. Experience has shown that the best treatment in such a case is the administration of a saHne cathartic, such as a Seidlitz powder or a one- grain pill of calomel, every three hours till the bowels move. Such a course is often rewarded by finding at the next visit a perfectly flat abdomen and a happy patient. Suppurative peritonitis is practically the same disease as septic peritonitis, the only difference being that in the suppurative form the process is less rapid, and pus has time to form either in localized abscesses, walled off by adhesions, or in one large collection in the general peritoneal cavity. Septic peritonitis is general, and results in death before suppuration has time to declare itself Suppurative peri- tonitis is more likely to be localized, and is therefore more amenable to surgical treatment. Pain is very severe ; there is usually a chill to usher in the disease; and the temperature rises to 102° or 104° F. In perforative cases gases in large quantities collect in the cavity, causing distention of the peritoneum, and are recognized by absence of liver and splenic dulness, as already mentioned. When pus collects in considerable quantity, its presence can be detected by dulness on per- cussion in the most dependent portions, just as in the case of ascites. Vomiting and constipation are the most characteristic symptoms, and so pronounced are they that we often have to decide the question as to whether the case is suppurative peritonitis or intestinal obstruction. To do so we must remember that in obstruction a tumor may be felt, the movements of the intestinal coils can be seen through the abdom- inal walls, the temperature is not high from the beginning, and as time goes on the vomiting becomes fecal in character. Temperature is not an infallible guide, for while the rule is that in peritonitis it is high and in obstruction not raised above normal (except there be complications), some of the worst cases of peritonitis are free from a rise of tempera- ture throughout their course. Treatment. — To guard against suppurative peritonitis the greatest care must be observed in the details of all abdominal operations. Asepsis must be observed most scrupulously, the peritoneal toilet must not be lost sight of, complete arrest of hemorrhage must be ensured, and the cavity dried with aseptic sponges. Should there be infection already established or a likelihood of a collection of serous or sanguin- eous fluid, a drainage-tube must be employed. At the slightest indi- cation of peritonitis a saline cathartic should be given, the action of which is increased by the use of turpentine enemata. Opium in such cases is to be avoided. Perforative peritonitis requires a somewhat different line of treat- ment. It would make matters worse were we to increase the peristaltic action ; consequently, purgatives of every kind must be avoided and a judicious use of opium resorted to. If a diagnosis of perforation be made, the repair of the perforation by operative measures should be attempted. With this object in view an incision is made in the linea alba, unless the point of the disease can be located elsewhere. If the opening in the intestine cannot be readily found, recourse should be had to the hydrogen-gas test. The rent is to be closed by sutures, as already described under Rupture of the Bowel, the abdominal cavity 286 SURGICAL DIAGNOSIS AND TREATMENT. thorouglily flushed with Thiersch's solution, a drainage-tube inserted, and the wound closed and dressed. Fibro-plastic peritonitis is a variety characterized by a tendency to numerous adhesions. The disease is probably identical with septic peritonitis, except that there is not a general intoxication of the system by ptomains, owing to a less violent character of the bacteria or a greater resisting power of the system. It commonly terminates in localized suppuration. Tubercular Peritonitis. — Tuberculosis may attack the peritoneum simultaneously with other structures, such as the lungs, the bones, or the joints. These cases are not of surgical interest. It is also a fact that the peritoneum may be attacked primarily, and remain the only seat of the disease. In this form it is of the greatest interest to the surgeon, since it has been found amenable to treatment in a very satisfactory degree. The disease is not limited to any particular period of life, but follows pretty much the same law as tuberculosis of the lungs, the majority of cases occurring between the ages of twenty and forty. In the diagnosis of tubercular peritonitis we must not expect to find the disease follow^- ing a uniform course in every case. Osier makes the following classifi- cation : 1. Acute miliary tuberculosis, characterized by a sudden onset, a rapid development, and a serous or sero-sanguineous exudation. 2. Chronic, caseous, and ulcerating tuberculosis, characterized by larger tuberculous growths which tend to caseate and ulcerate, leading often to perforation between the intestinal coils, and by a purulent or sero-purulent exudation, often sacculated. 3. Chronic fibro-tuberculosis, which may be subacute from the out- set, or it may be the termination of the miliary form. This variety is attended with slight exudation if any. The tubercles are hard and pig- mented. Although this classification is based on a correct pathology, w^e have no means by which we can differentiate from a clinical stand- point. The diagnosis of tubercular peritonitis is not always easy. Bearing in mind the manner in which tuberculosis acts elsewhere, we are pre- pared to find it following a slow and chronic course. There are cases, however, in which its development is rapid. We may reasonably look for the leading symptoms by which we detect ordinary peritonitis — viz. pain, tenderness, tympanites, fever, etc. — but these have not here the significance which attaches to them in the other varieties of peritonitis. They may be sudden in their onset, or they may come on so slowly that distention of the abdomen is the first symptom to attract attention. All the symptoms may be apparent at one time, and then subside. This is just like tuberculosis, for do we not find in pulmonaiy phthisis that a patient has his periods of improvement and decadence? Pain is usually slight, but in exceptional cases very severe, and tenderness to pressure is in direct proportion. The temperature is also variable. As a rule, there is little elevation, and generally we find it in proportion to the pain and tenderness. Enlargement of the abdomen may be due to ascites or to meteorism or both. Should peritoneal adhesions take place, collections of fluid may thus be encapsulated, giving the appear- v\ INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 287 ance of cystic tumors. Even when the distention is due to meteorism, round elastic tumors can be felt, which do not change their position when the patient is moved to one side or the other. These tumors are formed in a variety of ways. Coils of intestine may become adherent and form a mass resembling a solid abdominal tumor ; the omentum may become thickened and curled upon itself; mesenteric glands, especially in children, are liable to be the seat of tubercular enlarge- ment and attain considerable size, and circumscribed collections of fluid walled in by strong adhesions constitute the last class of these deceptive tumors. The abdominal wall is frequently found to have more than a normal resistance, due to a thickening of the peritoneum. Vaginal or rectal examinations will also demonstrate a thickening of the membrane. A sign of great importance in the diagnosis of tubercular peritonitis is an erythema which in some cases surrounds the umbilicus. This is regarded by Dr. Henry ^ as pathognomonic, and is shown in Fig. Many diseased conditions may be mistaken for tubercular peritonitis. In fact, a large proportion of the cases which have been operated upon have been incorrectly diagnosed. The errors have been fortunate ones, for by them surgeons have stumbled on a treatment which is very suc- cessful. In 1864, Spencer Wells, operating upon what he supposed to . be an ovarian tumor, found on opening the abdomen that the fluid was free in the peritoneum, while the membrane itself was studded with miliary tuberculosis. The patient recovered, and was free from disease twenty-six years afterward. Against tubercular peritonitis the following must be carefully differ- entiated : 1. Abdominal tumors. An ovarian cyst has many points in com- mon. In it, however, there is generally a freedom from pain, tender- ness, and fever until the tumor has attained to a larger growth. Bimanual examination will also prove of value in the majority of cases. Pyosalpinx or hydrosalpinx has its characteristic attacks of localized pain, a history of disordered menstruation, and the cha- racteristic tumor felt on examination. Pyonephrosis and hydronephro- sis have their renal manifestations. An enlarged gall-bladder is con- nected with the liver, and ascends and descends with respiration. Malignant tumors in the abdominal cavity are usually more rapid in their progress than tubercular peritonitis, and frequently are but extensions of the disease from other parts. 2. Ascites of non-tubercular origin. This may be excluded by taking into consideration the etiology of ascites. The condition of the liver, the existence of jaundice, and a careful examination of the urine will generally settle the point. 3. Typhoid fever. Acute tubercular peritonitis may closely simu- late typhoid fever. The points which aid in differentiation are — the absence of typhoid spots, the less constant diarrhea, the absence of the typical remissions of temperature, and the non-limitation of the point of tenderness to the cecal region. In spite of every precaution the case may puzzle the most expe- 1 htternational Clinics, vol. iv. 5th series. • 288 SLKG/CAI. lUAGXOS/S AND TREATMENT. riciiccd, and the real state of matters be only found after oi)eninic)it. — A child subject to prolapsus should be prevented from straining at stool. He should have an attendant who will remove him from the commode as soon as the bowels are evacuated. When the bowel protrudes it should be wiped with a soft cloth wrung out of cold water, gently pushed back, and retained by a T-bandage or by broad strips of adhesive plaster applied so as to keep the buttocks together. I have found great benefit from the use of astringent injections given once a day. Alum, gallic acid, or hydrastis serves the purpose. These children are usually debilitated, and require iron tonics and cod-liver oil to build them up and improve their general health. Con- stipation should be prevented by the judicious use of a mild laxative. When the prolapsed bowel remains down in spite of the ordinary efforts of the nurse or mother to return it, the aid of the physician is sought. The best position for reduction is on the knees and elbows. The bowel, having been washed with cold water, is anointed with vaselin. The surgeon then inserts his finger into the rectum, and by taxis practised around the finger the bowel easily slips back to its normal position (Mathews). Sometimes the bowel goes up more readily if the finger is covered with a soft handkerchief or a piece of lint. Should these measures fail, give an anesthetic, w'hich, by quieting the voluntary movements and relaxing the sphincter, allows the bowel to go back without dif- ficulty. To prevent a recurrence several operative procedures have been recommended. The mucous membrane may be cauterized in strips by solid nitrate of silver or nitric acid. The cautery has been a favorite remedy with many surgeons, owing to the contraction which follows its application. It should be applied in the long axis of the bowel in four lines a quarter of an inch wide (Cripps). After the cautery has been quickly passed over the surface in this manner a tube is passed into the rectum a distance of five or six inches, and the space around it packed with iodoform and absorbent cotton. The bowels are kept quiet by opium for about ten days, and defecation allowed only while lying on the side. In aggravated cases a more radical operation may be called for, and we have a choice of several procedures : {ci) One or more of the folds of the mucous membrane may be removed by the clamp and cautery. (^) A V-shaped piece may be removed from the sphincter and the edges brought together by sutures, {c) A V-shaped portion is removed from the posterior part of the sphincter and the entire thickness of the rectum, having a common base below (Roberts). (^) The protruded mucous membrane may be excised and the lower edge of the remainder attached to the skin (Treves). INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 329 Pruritus Ani. — A complication of many diseases of the rectum and anus is a very distressing itching. In some cases this disagreeable sensation is constantly present. In others it is quiescent during the day, but just as the patient is getting warm in bed and sleep begins to steal over him an intolerable itching around the anus begins, and he spends a wretched night. Scratching makes matters ten times worse. After enduring this torture for an indefinite time, the patient consults the physician for what he terms " itching piles." Examination shows thickened, hardened, excoriated skin around the anus, often eczematous from constant irritation, and the patient can scarcely keep his fingers off, so urgent is the desire to scratch. Further investigation will lead to the discovery of hemorrhoids, prolapsus, stricture, or other rectal disorder. Sometimes the only apparent derangement is a mucous secretion which keeps the parts moist. Many people suffer only during periods of constipation or when the functions of the hver are being imperfectly performed, and in others the affection is a pure neurosis. Alcohol and highly seasoned foods have been known to act as exciting causes, and women suffering from uterine diseases appear to form a large class of cases. The itching is most intense just inside the anus, and extends about an inch up the rectum. The inferior hemorrhoidal nerve supplies this area as well as the skin in the neighborhood of the anus, which explains anatomically why the itching so uniformly extends over these surfaces. Treatment. — The treatment of pruritus is .very unsatisfactory and its results uncertain. When it is possible to ascertain and remove the cause this should be done. If thread-worms are present, injections of the infusion of quassia should be employed. Whatever rectal diseases coexist should receive prompt treatment. For the relief of the itching I have found nothing so generally useful as calomel, either applied in powder or made into an ointment with vaselin. Inasmuch as the most trouble is experienced after the patient goes to bed, Mathews recom- mends that the parts be bathed in water as hot as can be borne, then wiped dry and the following lotion applied : 3^. Campho-phenique, 3j ; Aquae dest., 3J. — M. Morain paints the parts night and morning with a mixture con- taining 60 grains of alum, 30 grains of calomel, and 300 grains of glycerol. To produce sleep 10 grains of sulphonal may be given. Local applications, however, will produce no permanent benefit as long as there is a thickened and scaly condition of the skin. To get rid of this the tincture of iodin is applied and renewed in two or three days, or a solution of nitrate of silver 20 or 30 grains to the ounce. After the removal of the scarf skin local applications of a milder nature can be used. Some of the preparations of tar have been very popular, as the oil of cade or marine lint (which contains tar) placed between the buttocks to prevent their apposition. A lotion containing a mixture of menthol and cocain and an ointment of oxid of zinc and 330 SURGICAL DIAGNOSIS AND TREATMENT. balsam of Peru arc favorite applications. Bulkley's ointment is the following : ^. Ungt. picis, Siij ; Untjt. belladonnae, Sij ; Tinct. aconiti rad., 3ss ; Zinci oxidi, 3j ; Aquae rosae, 3iij. After the disease has resisted every other treatment it may be cured by dilatation of the sphincter or by the wearing of a bone plug which keeps the anus slightly distended during the hours spent in bed. Inflammatory Diseases of the Rectum. — Inflammation in and about the rectum not only produces painful and troublesome conditions, but leads to secondary affections. Thus proctitis, or inflammation of the mucous membrane of the rectum, is likely to end in ulceration, while periproctitis paves the way for fistula in ano. Proctitis is a catarrhal inflammation of the mucous membrane of the rectum, and is due to irritation or infection. Among the causes, therefore, we find the abuse of purgatives, the presence of foreign bodies or hardened feces in the rectum, gonorrhea, gout, and syphilis. The disease may be acute or chronic. In the acute form the inflam- mation does not go deeper than the mucous membrane, which is congested and hyperemic. When the cause can be removed this variety gets well in from eight to fourteen days. In very exceptional cases, however, it may go on to gangrene of the bowel and end in death. In the chronic form the submucous and muscular layers are involved, the bowel-wall becomes thickened and infiltrated, and fre- quently the disease goes on to ulceration. Symptoms. — A sensation of burning and heaviness in the rectum is a pretty constant symptom. Naturally, this burning is attended with a frequent inclination to have a movement of the bowels ; the action is painful, and attended with tenesmus. Neighboring organs sympathize ; hence there is pain in the bladder, and frequent micturition, pain in the uterus with leukorrhea, pain in the sacrum, in the loins, and along the thighs. An examination of the parts will show that the anus is inflamed, painful, excoriated, and contracted. The mucous membrane of the rectum is intensely congested, and the temperature, even to the examining finger, is greatly increased. The feces are streaked with mucus, blood, and finally with pus. As a result of all this local dis- turbance there are constitutional effects, as fever, nausea, and loss of appetite. In chronic proctitis the symptoms are not so well marked. Diarrhea may alternate with periods of constipation. The pain is not so severe as in the acute variety. It is generally associated with stric- ture of the rectum. Below the stricture the mucous membrane is con- gested and covered w4th pus or bloody mucus, while above it is eroded or destroyed (Kelsey). Ulceration of the rectum is caused by the irritation of foreign bodies or the passage of hard, scybalous masses, or it is a conse- quence of chronic proctitis. Thrombosis and phlebitis are also causes. The ulceration may be superficial, simply involving the epithelial lining. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 33 1 or it may be so deep as to perforate all the coats of the bowel. This is, of course, a serious matter, but much depends upon the position of the perforation. If it is low down, it leads to abscess and fistula ; if it is above the reflection of the peritoneum, a fatal peritonitis is a probable termination. Syphilitic, tubercular, and lupoid ulceration are not uncommon in the rectum. We know that ulceration of the bowel higher up, such as occurs in typhoid fever, is attended with diarrhea. The same symptom attends ulcer in the rectum. In the early and milder stage the patient has a •call to stool as soon as he gets out of bed. He passes a small quantity of liquid feces containing mucus like the white of an &%^. Once or twice in the forenoon this is repeated. The rectum is now empty, and the rest of the day is spent in comparative comfort. The condition is apt to get worse ; diarrhea increases in frequency and is attended with painful straining ; from mucus the motions change to a dark coffee- ground material ; the skin about the anus is constantly moist, covered with vegetations and excrescences, giving rise almost invariably to itching. When you make a local examination you find that if the ulcer is about the anus, it takes the form of a fissure, which is usually exceedingly tender. If inside the sphincter, the ulcers lie deep between the folds, and so sensitive are the parts that for an examination with the speculum an anesthetic is required. The finger, however, is gen- erally sufficient, and it should be introduced with the greatest gentle- ness. The point of the finger will meet with a variety of conditions : in one part are felt soft, smooth patches with ragged, overhanging edges ; in another hard nodules project from the surface or dense bands of cicatricial tissue traverse a part of the circumference of the bowel, simulating stricture. When the finger is withdrawn it is usually smeared with mucus and blood. An ulcer due to syphilis is found near the verge of the anus, and makes its appearance during the first year after the contraction of the initial lesion. Inherited syphilitic ulcer appears three or four months after birth. The tertiary stage has also its rectal ulcers which are due to the breaking down of gummata. The tubercular ulcer may occur as a primary lesion or as a secondary mani- festation of tuberculosis in other parts. It is oval in shape, its long axis corresponding to that of the bowel ; its edges are ragged and under- mined, and it often ends in fistula and abscess. Treatment. — Removal of the cause and the securing of perfect rest are the first requisites. Injections which will cleanse and soothe the bowel are very useful. A solution of chlorate of potash, followed by an enema of starch and a few drops of laudanum, gives great comfort in the milder cases of proctitis. A dose of castor oil or small doses of a saline aperient should be given to remove acrid contents of the bowel. The diet should be light and easily digested, and such articles avoided as tend to form bulky stools. Bread, meat, and vegetables are to be avoided. Milk, soft-boiled eggs, and prepared foods are generally satisfactory. In chronic cases astringent injections of alum, tannin, nitrate of silver, and suppositories of iodoform are recommended. Constitutional treatment must be directed to the existing conditions. Syphilitic cases require iodid of potash. Cod-liver oil is valuable, as it 33^ SURGICAL DIAGNOSIS AND TREATMENT. not only tends to replace the waste of flesh, but it keeps the motions soft. Operative interference may be required, but is not to be hastily adopted. In obstinate cases benefit has been derived from stretching or dividing the sphincter, and where every local remedy has been tried in vain colotomy has been resorted to. Periproctitis. — Inflammation around the rectum may occur in one of three situations — close to the anus (marginal), in the ischio-rectal fossa, or higher up about the insertion of the levator ani and the recto- vesical fascia. 1. Margi)ial. — This is a superficial inflammation involving the skin onh' of the margin of the anus. It is merely a collection of pus orig- inating in one of the small glands of the part, and may be caused by a traumatism or any irritation, such as the pressure of a rough seat, the use of improper toilet-paper, or unhealthy discharges occurring in menstruation, diarrhea, or dysentery. The swelling is seldom larger than an almond ; it rapidly goes on to the formation of an abscess and opens on the cutaneous surface. In phthisical persons it not infre- quently ends in a fistula. Instead of appearing at the cutaneous sur- face, this little abscess may form near the mucous membrane, and usually it is the result of an inflamed internal hemorrhoid at, or just inside, the sphincter. It varies in size from a grape to an almond, and is excessively painful. This is the starting-point of nearly every blind internal fistula. After a few days of suffering the abscess bursts into the bowel, and the escape of pus from the anus accounts for the whole trouble. Treatment. — The important practical point in all inflammations about the rectum is the danger of their resulting in fistula. In order to pre- vent such a termination the abscess should be opened as early as pos- sible and at right angles to the folds, so as to secure gaping of the wound. The incision should be kept open and the cavity allowed to heal from the bottom. Another form of superficial abscess occurs in the subcutaneous tissue ; hence it is more diffuse and more difficult to dispose of than the preceding. The diagnosis needs no special mention, except that fluctuation is best elicited by placing one finger in the rectum and the other outside. Early and free incision is the only treatment. 2. Ischio-rectal Abscess. — Bounded above by the levator ani and below by the skin, on the inside by the rectum, and on the outside by the pelvis, is a space which is a favorite position for suppuration. The most common cause for ischio-rectal inflammation is trauma- tism. Generally the injury is from within the rectum. The rough use of a syringe and the swallowing of fish-bones or other sharp objects figure largely in the causation. External to the rectum the causes are kicks and blows, the pressure of the fetal head during parturition, ex- travasation of urine from ruptured urethra, and necrosis of the sacrum, the coccyx, or the lumbar vertebrae. Symptoms. — The disease may be obscure at its onset, the patient complaining of a dull pain about the pelvis and loins, with general malaise, or the symptoms may be acute chills, high temperature, and severe pain. The first definite symptom will probably be pain in INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 333 defecation, which is often so severe as to amount to perfect torture. Constitutional symptoms become more marked, such as high tempera- ture, rapid pulse, and occasionally chills. On local examination a hard brawny mass is felt on one or other side of the anus, which later becomes red and fluctuating. Sometimes the tendency of the abscess is to burrow upward to the prostate and urethra, in which case there are retention of urine and other symptoms pointing to prostatic or urethral complications. Examination by the finger or speculum is generally so painful as to be out of the question. If not opened early, this abscess is apt to burst into the rectum, forming a fistula. A chronic form of the dis- ease is met with in the feeble, debilitated, and phthisical. 3. Abscess above the Levator Ani Muscle. — The levator ani forms a sling-like support for the lower part of the rectum. It arises on either side from the posterior surface of the pubic bone below the symphysis, from the curved white line indicating the separation of the obturator and recto-vesical layers of the pelvic fascia, and from the inner surface of the spine of the ischium (McClellan). Passing downward and inward toward the middle line, the muscle is inserted around the rectum between the internal and external sphincter ani muscles. Inflammation and suppuration above this muscle is a very serious matter. The abscess may assume enormous proportions, blending laterally with the subperitoneal connectiv^e tissue of the iliac fossa, and burrowing in almost any direction in the true pelvis (Kelsey). The disease is generally an extension from some of the neighboring viscera or the result of stricture in the rectum. It is not uncommon after parturition or metritis, the disease in this case extending from the uterus, thus causing stricture of the rectum to be much more common in women than in men. In men the pus generally burrows along the side of the bowel, making its way into the ischio-rectal fossa, and finally through the skin of the perineum at some distance from the anus. In females it not unfrequently burrows upward, reach- ing the skin about the crest of the ileum or in the groin. Not unfre- quently the abscess ruptures into the rectum. We then have a charac- teristic symptom. Pus is discharged at each act of defecation. If the opening is near the anus, the pus comes before the feces ; if it is above the rectal pouch, it comes after the feces. In very exceptional cases the abscess ruptures into the bladder, the uterus, the peritoneum, or the vagina. Treatvioit. — Early incision is here the only proper course. As soon as diagnosis of the existence of pus is made, even before fluctuation is detected, the patient should be anesthetized and the abscess freely and deeply incised. All pockets should be explored, thoroughly evacuated, and made to communicate freely with the main cavity. This should then be well irrigated with a i : 2000 sublimate solution, dusted with iodoform, and packed loosely with iodoform gauze. A drainage-tube should be inserted and the cavity made to granulate from the bottom. Fistula in Ano. — Any of the forms of abscess just mentioned may heal to a certain point and then remain stationary, keeping up a con- stant discharge of pus by an opening into the rectum or externally through the skin, or in both directions. When the fistula has an open- 334 SURGICAL DIAGNOSIS AND TREATMENT. ing through both skin and rectum, it is called complete; when the open- ing is in only one direction, it is termed incomplete or blind. A fistula whose only opening is into the rectum is a blind internal fistula, and one opening only through the skin is a blind external fistula. Fistuke may be divided into anal and rectal. In the first class the opening is close to the anus, almost entirely subcutaneous or penetrat- ing some of the lower fibers of the sphincter. They are generally the sequelae of marginal abscesses. Rectal fistulae are deeper, traversing the ischio-rectal fossa and passing into the bowel between the external and internal sphincter or even above the internal. Sometimes there are numerous fistulous channels running in different directions until the perineum is fairly riddled by them (Fig. 144). Pus burrowing in Fig. 144. — Horseshoe fistula with multiple openings (Gant). the loose tissues of the perineum may travel far, and thus the external opening is often found at a considerable distance from the anus. Some cases have been recorded in which the opening was in the groin, others in which pus burrowed beneath the gluteal muscles and opened in the thigh and even the popliteal space. The walls of the fistula are gen- erally thickened by increase of fibrous tissue, the result of chronic inflammation ; the surface is covered w^ith granulations which secrete a thin purulent fluid. The external opening is generally small, scarcely admitting a probe, and sometimes surrounded by a mass of granula- tions. The course of the channel may be direct from the skin to the rectum, and the point in the rectum which is the seat of the opening is about an inch from the anus or between the internal and external sphincter. Sometimes the sinus runs partly around the rectum, giving what is called a horseshoe fistula. Symptoms. — The early histor}^ of a fistula is the history of the abscess which produced it. Generally the patient seeks advice long after the abscess has discharged. He expects the opening to heal, and, as it gives no trouble beyond a daily discharge of pus and serum, he bears the inconvenience until the opening closes temporarily and a INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 335 new collection of pus takes place. The skin at such a time becomes red and tender, movement of the bowels causes great pain, and the symptoms of abscess are repeated until discharge of pus takes place, either by the old or through a new opening. In the ordinary condi- tion of the fistula the skin about the part is always moist, sometimes eczematous or covered with small boils. In the subcutaneous tissues fistulous tracts can always be detected by their hard, resistant feel. From the opening escapes a thin purulent fluid, always offensive in smell ; when the opening is large enough, gas and even feces escape. These are positive signs of fistula, but the variety of fistula must be determined by further examination. Place the patient on the affected side with the knees drawn up. The external opening is generally easily found, but sometimes it is concealed between the folds of skin or it may be temporarily closed. Even then its position can often be determined by the induration and thickening of the tissues at that point. Having found the external opening, a probe is inserted and gently pushed toward the opening in the rectum. Here let me warn you against two common errors : Do not look for the internal opening too high up. It is generally between the internal and external sphincter. Do not pass the finger into the rectum until you have pushed the probe as far as it will go. The presence of the examining finger causes the sphincter to contract violently, which changes the relation of the fistu- lous track and prevents the probe passing through it. Insert the finger after the probe has passed as far as it will go. If the course is moder- ately straight, the examining finger will find the point of the probe in the rectum. If the probe has not passed through the internal opening, the finger must search for it. No matter how many external openings exist, there is only one internal. The finger can generally detect it even if the probe does not go through. In some cases the end of the probe can be felt with only a thin portion of the mucous membrane between it and the finger. This is sufficient. Push the probe through this thin spot. A valuable aid to diagnosis which I have never found to fail is the injection of peroxid of hydrogen. A speculum is introduced, the per- oxid injected by the external opening, and its appearance watched for at the internal opening. If a fistula be present, the froth caused by the peroxid will be seen to ooze through the internal opening, and in a short time it almost fills the rectum. A diagnosis of the fistula and the kind of fistula is not sufficient. A very important practical point remains to be settled : Is there a stricture of the rectum ? Sometimes stricture and fistula coexist, the stricture being high up and the fistula near the anus. To operate on the fistula and overlook the stricture would be a bungling piece of work. Again, the abscess which led to the formation of the fistula may have been due to necrosis of the sacrum, coccyx, or vertebrae. An operation dealing only with the fistula would be worse than useless. Blind internal fistulae have generally large openings, and it is not uncommon to find that feces enter this cloaca viaxhna and keep up irritation which prevents healing for an indefinite time. These fistulae are generally painful, not only during defecation, but when pressure is made externally near the anus. Diagnosis of this variety 336 SURGICAL DIAGNOSIS AND TREATMENT. is made by fcelin<:;^ the internal opening and by passin<^ a bent probe through the anus and into the fistula. Treatment. — Palliative treatment is of little or no avail in fistula. A free incision conv^erting the fistulous track into an open wound, which is allowed to heal from the bottom, is the most satisfactory treatment. An aperient is given the night before, and an enema of soap and water on the morning of the operation. The patient is anesthetized, and placed either in the lithotomy position or on his side with the limbs well drawn up. A grooved director is passed by the external opening through the fistula and out at the anus, and then a curved knife is made to run along the groove (Fig. 145), dividing all the tissues, cut- FlG. 145. — Typical case of fistula in ano, with operation for the same (Gant). ting the fibers of the sphincter as nearly at right angles as possible. The track of the fistula should then be scraped with a Volkmann's spoon to remove all granulation-tissue. A packing of iodoform gauze and a pad of sterilized gauze and absorbent cotton held in position with a T-bandage complete the operation. The bowels should be kept confined for two days and the wound repacked daily with great care. In horseshoe fistula the incision on one side should be made in the usual manner, while the opposite sinus should be freely dilated and drained. To open up both fistulae would necessitate division of the sphincter in two places. This will almost to a certainty be followed by incontinence. Goodsall recommends the following method of operating on horse- shoe fistula : First pass a probe-pointed director through the internal aperture, and on its point incise the skin in the middle line behind ; then push the director through, and slit up. Second, slit up the lateral sinuses on directors passed in at the external openings and brought out at the external incision. When numerous external openings exist it may be necessary to open up several of the sinuses and leave others for a second operation. A tortuous fistula, instead of being cut through at once, should be dissected up on a director from the external opening. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 337 Sinuses which are offsets from the main fistula can be followed up in the same manner. The walls of the sinus should be dissected out and the wound packed with iodoform gauze. Closing the wound by su- tures with the view of obtaining primary union is sometimes successful, but I have known cases in which this plan was attempted with very unsatisfactory results. The fistulous tracks retained suppurating mate- rial and necessitated operations at a later period. Fistula in phthisical subjects should be operated upon under certain restrictions. A cough which is violent and frequent is a contra- indication, as it prevents healing of the incision. In rapidly advancing lung disease, in persistent diarrhea, or in an advanced stage of tuber- culosis in any organ it is not advisable to operate. In ordinary cases of phthisis complicated with fistula improvement may be expected after treatment of the fistula, for, although the pulmonary disease may render the condition of the patient hopeless, he is saved the misery of a very exhausting complication. Other methods of treating fistula have been advocated from time to time. Injections of iodin and of nitrate of silver have been known to cure, so also has dilatation of the mouth of the sinus, but the effect of such remedies is so uncertain that they scarcely deserve mention. The elastic ligature is employed in patients who are strongly opposed to the use of the knife. It is also recommended in a fistula whose inter- nal opening is high up in the rectum. In every other case it is far inferior to incision. The ligature when employed should be of solid rubber about one-tenth of an inch in diameter. It is passed through the fistula and out the anus, then tightly secured by means of a lead clamp. Fissure of the Anus. — A fissure or small ulcer at the anal orifice, attended with the most excruciating pain, and producing symp- FlG. 146. — Painful ulcer (fissure) of the anus (Gant). toms out of all proportion to the extent of diseased tissue, has been spe- cialh' named anal fissure or irritable ulcer (Fig. 146). Its commonest situation is on the posterior wall of the rectum about the junction of the skin with the mucous membrane. It is not uncommon to find it lying under a small hemorrhoid, presenting the appearance of a little fissure lying between two folds of muco-cutaneous tissue. If, however, 22 338 SURGICAL DIAGNOSIS AND TREATMENT. the folds be separated and the anus dilated, the shape changes to a round or oval ulcer. After all, there is nothing special about this form of ulcer, for it can be caused by anything which causes an abrasion or laceration of the tissue at the anal orifice. Its position gives it two characteristics which, kept in mind, make it easy to understand the disease : It is exceedingly painful, and therefore well named irritable ulcer. This is the first cha- racteristic. The junction of skin and mucous membrane is always a highly sensitive line. An ulcer of the mucous membrane alone, how- ever slightly removed from this line, is not nearly as painful. The extreme sensitiveness of the ulcer causes reflex contraction of the sphincter ani muscle, which is the second characteristic. Symptoms. — There is nothing that can compare with a severe case of anal fissure. The patient at stool experiences a pain which he believes is tearing his anus or burning the part as with a red-hot iron. He is thrown into a state of collapse ; the pulse becomes feeble, the surface of the body is damp and cold, and beads of perspiration break out on the forehead. For hours this may continue, and the sufferer naturally dreads to have a movement of the bowels, and they are allowed to become constipated. This only increases the suffering by hardening the feces and making defecation more painful than ever. Blood to the extent of a drop or two is sometimes seen on the motions. Retention of urine is common in men, and menstrual disorders in women. The sphincter is rigidly contracted and feels hard to the touch. Digital examination is out of the question without an anes- thetic. An inspection shows a fissure, usually on the posterior wall, and taking a round or oval form when the anus is dilated. The surface is covered wdth red, inflamed granulations or a thin slough. In these red granulations are the exposed nerve-filaments to which are due the extreme sensibility. Hemorrhoids, blind internal fistula, and sphincter- ismus might be mistaken for ulcer. Treatment. — In mild cases healing of the ulcer may be secured by astringent ointments, the application of weak solutions of nitrate of silver or sulphate of zinc, and by keeping the bowels in a relaxed con- dition. In more severe and obstinate cases the patient may be given an anesthetic, and the ulcer then freely cauterized with nitrate of silver or the acid nitrate of mercury'. The bowels are kept from acting for a day or two, and the patient keeps his bed until the ulcer heals. The most obstinate cases are those in which the sphincter is hyper- trophied from constant contraction, and these require a more radical method of treatment. To overcome the action of the muscle its superficial fibers can be divided or it can be fully stretched. The patient is placed under chloroform ; the sphincter is then stretched with the thumbs, and the floor of the ulcer divided with a knife down to the extent of a quarter of an inch, which is sufficient to sever the super- ficial fibers of the sphincter. The base of the ulcer should be dissected out and the wound packed with iodoform gauze. At the same time, any small hemorrhoid, polypus, or tag of skin should be removed ; a sinus, if present, should be opened up, the upper region of the rectum examined, and in the case of females any retroversion of the uterus corrected. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 339 Spasm of the Sphincter (Sphincterismus). — This is an affec- tion which is most commonly seen in fissure of the anus, but it also exists in hysterical women, and in persons suffering from diseases of neighboring organs, as the uterus or bladder. In some cases there is an undiscoverable cause. When due to fissure this latter condition should be attended to ; in hysterical women a suppository containing two grains of the extract of belladonna is very efficient, and in obsti- nate cases from any cause, stretching the sphincter is an almost certain cure. Tumors of the Rectum. — Of the benign growths the most common in the rectum is polypus. The term polypus, however, is applied to any growth projecting from the mucous membrane into the cavity of the bowel. Sometimes it is an hypertrophy of the mucous membrane, sometimes a fibroma or an adenoma (Fig. 147), sometimes Fig. 147. — Fibrous (hard) polypus (Gant). a villous growth. Polypi are generally single, occurring frequently in children below nine years of age. They are usually attached to the posterior surface of the rectum and not far from the anus. In size they seldom reach the dimensions of a walnut, but they have been found in such numbers as to block up the bowel and produce symptoms of intestinal obstruction. Symptoms. — When a child has hemorrhage from the rectum polypi should always be suspected. Just as in uterine polypus, hemorrhage is a pretty constant symptom. A digital examination of the rectum should always be made in such cases, when, if a polypus be present, it will be felt hanging from the rectal wall, usually the posterior sur- face. When the pedicle is long, however, it may be directed upward, so that the tumor is out of reach. On this account an enema of warm water should be given before the examination. The expulsion of the fluid brings down the polypus to the full length of its pedicle (Fig. 148). The length of the pedicle varies greatly. In some cases it is so long that the tumor escapes through the anus during defecation, and it not infrequently happens that the sphincter, contracting firmly on the pedicle, strangulates the growth and causes it to drop off, thus effecting a spontaneous cure. The diagnosis of polypus with a long pedicle is very simple. It is a very different matter when the attachment of the tumor is broad and 340 SURGICAL DIAGNOSIS AND TREATMENT. the pedicle absent. The question then arises as to whether the tumor is benign or maUgnant. Diagnosis must rest upon the following points : 1. In children malignant disease is exceedingly rare, while polypi are frequently met with. 2. Malignant tumors are not extruded and are not pedunculated, so that the existence of even a very short pedicle is strong evidence of polypi. In adults an adenoid polypus which has ulcerated and which is not pedunculated cannot always be distinguished from malignant disease,. Fig. 148. — Adenoid (soft) polypus (Gant). either by the microscope or the clinical history ; for the ulcerated and bleeding tumor may cause a wasting and cachexia which strongly resemble cancer (Kelsey). Treatment. — The treatment of polypi is very simple when the tumor is pedunculated. Hemorrhage is the only danger, and this can be obviated by first throwing a ligature around the pedicle and then dividing the tissue with scissors close to the point of ligation. Some- times the pedicle is so long and slender that the tumor can be twisted off by grasping it with forceps and making simple torsion. When polypi have no pedicles, they must be removed in the same manner as ordinary tumors, and the bleeding stopped by forceps and by packings with gauze or sponges wrung out of hot water. Removal of polypi by clamp and cautery is advocated by some authors. Papillomata, Warts, or Vegetations. — These warty growths occur about the anus in persons who are the subjects of warts in other parts of their bodies. Their development is favored by the presence of any irritating discharge, such as occurs in gonorrhea, leukorrhea,^ or any disease of the rectum. Formerly these growths were held in very bad repute, being considered positive evidence not only of syphilis but of sodomy. Molliere relates how in the time of Dionysius there was a hospital in Rome for the treatment of these growths ; the sur- geons, according to Dionysius, spared neither the iron nor the fire, and were not moved to pity by the cries of the patients, inasmuch as this disease was the result of unnatural intercourse between man and man (Molliere, quoted by Kelsey). The ideas of surgeons have undergone considerable change in recent years, the cause now being considered to be a tendency to warts, plus a local irritation. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 34 1 Symptojjis. — While papillomata occur at almost any age, they are most frequently found in adults. The appearance will vary according to the number of warts. When occurring singly the surface is dry ; when existing in numbers they secrete a fluid of very disagreeable odor. This secretion is irritating, and not only causes inflammation in the warts themselves, but in the surrounding skin. When the growth begins on one side of the intergluteal fold, the pressure of their moistened surface against the opposite side produces a second growth at that point. The patient suffers great discomfort from the odor and irritation, and not infrequently defecation is attended with considerable pain. Little difficulty is experienced in the diagnosis of these growths ; the most common error arises by mistaking them for syphilitic condylomata or for mucous patches. The surface of a flat condyloma or mucous patch is smooth and different from the cauli- flower-like growth of a papilloma. The papilloma, moreover, is found to be attached to the skin by a number of small pedicles, so that if the whole growth be cut off at the level of the skin, it does not leave a raw surface, but a number of minute bleeding points. Treatment. — Excision with knife or scissors is the best and most rapid treatment. Applications of strong astringents, such as tannin or alum or strong acetic acid, are sometimes sufficient to remove them. Condylomata. — This is a term applied to several different growths about the anus, as the raised mucous patches and the remains of exter- nal hemorrhoids. There is a growth known as condyloma which is non-syphilitic. It is attached by a broad base, is of a pink color, soft, fleshy, moist, and flattened where two are pressed together. Condy- lomata generally begin at a fold of the anus (Kelsey). They are due to a localized chronic inflammation of the skin. They are most likely to be confounded with syphilitic gummata. Syphilitic condylomata begin as red spots with slight effusion beneath the epidermis. The thin covering formed by the epidermis is rubbed off, and a raw surface is left covered with a thin pellicle. Upon this surface a new growth takes place, composed of papillae, connective tissue, and blood-vessels. In this respect it closely resembles the papil- lomata, and in fact their appearance is sometimes identical. Diagnosis must rest, therefore, upon the history, the mode of development, and the results of treatment. Fibromata, lipomata, villous growths, enchondromata, and sarcomata are so rare as to need no special mention. (For cancer of the rectum see Cancer of the Intestines.) Stricture of the Rectum. — Stricture of the rectum may be due to changes in the bowel-wall which lessen its caliber, or to pressure from without. Tumors in the pelvis by gradual encroachment on the rectum may cause a diminution of its caliber, but this is generally an obstruction rather than a stricture. Two classes of stricture are recognized — simple and malignant. The latter has been discussed in the section on Rectal Cancer. Simple stricture is generally associated with inflammation, and, bearing this in mind, its etiology is readily understood. Inflammation, and especially the chronic form, tends to increase the connective tissue of the part affected. The connective tissue of the rectum is arranged in a circular 342 SURGICAL DIAGNOSIS AND TREATMENT. manner around the bowel, so that inflammation by increasing this fibrous tissue causes a constriction. We have, therefore, the following among the causes of simple stricture : 1. Traumatism, such as kicks, blows, the application of strong acids, operations on the rectum, ulceration, and the presence of foreign bodies. All of these produce stricture close to the orifice of the anus. 2. When the stricture is higher up the principal causes are — ope- rations for internal hemorrhoids, tuberculosis, syphilis, dysentery, parturition, pelvic cellulitis, and imperforate rectum, partial or complete. Strictures arising from any of these causes may affect a small or a large portion of the rectum, and two varieties are spoken of according to the extent of the stricture. If it involves an inch or less, the stric- ture is called anmtlar (Fig. 149); if more than an inch, it is tubular (Fig. 150). Fig. 149. — Diagrammatic drawing of annular stricture (Gant). Fig. 150. — Diagrammatic drawing of tubular stricture (Gant). Syviptoms. — Of seven patients suffering from stricture of the rectum, six are women. Common sense tells us that the leading symptoms are obstruction, due to narrowing of the bowel and irritation and inflam- mation which produce the stricture. When high up obstruction may be an early symptom, and may appear with very slight warning. In stricture low down it does not appear until a late period. The first symptom is generally a diarrhea coming on when the patient gets out of bed and after each meal. The motions are either small like pellets, or ribbon-shaped and covered with mucus. Later on, constipation alternates with diarrhea. Pain becomes a prominent symptom, felt especially in the perineum and radiating to the hips and down the thighs. The sphincter loses its tonicity, becomes flabby, and, later on, raw and excoriated. There is a constant offensive discharge about the anus which keeps the parts moist and irritated. Later on, obstruction becomes more apparent. In some cases the transverse and descending colon can be felt distended with feces, dull on percussion, sensitive to touch, and retaining indentations made by pressure of the fingers. The bowels are never properly emptied ; abscesses, fistulae, and ulceration INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 343 are common ; and at last the patient dies either of peritonitis, the result of complete obstruction, or wastes away from sheer ex- haustion. No diagnosis is complete without a local examination, which can be digital or by bougies. The finger is preferable. A constriction, ring- shaped or tubular, is felt, which at once settles the question. Should the stricture be too tight to allow the finger to pass through, no attempt should be made to force it. Death has occurred more than once by rough examination. Having satisfied yourself that a stricture exists, examine the condition of the rectum below the narrowing. In females the vaginal examination may throw considerable light on the subject. No end of mistakes have been made by depending upon bougies. Many supposed strictures have proved to be nothing more than the arrest of the instrument by the promontory of the sacrum. When the stricture appears to be beyond the reach of the finger, something can be gained by having an assistant press the elbow of the examining arm, thus pushing the perineum well up. Olive-pointed bougies or long rectal tubes are sometimes useful. Stricture high up in the rectum or in the sigmoid flexure is very difficult of diagnosis. The symptoms complained of by the patient are different from those already described. Chronic constipation and dyspepsia are the most prominent. Pain is felt in the abdomen, generally, but not always, in the left side ; sometimes in the loins and down the thighs. An examination of the feces gives nothing satisfactory. The motions, being formed in the rectum, have not the ribbon or pellet-shape characteristic of a stricture low down. The most significant appearance is the presence of blood or slime in streaks in the feces. When the constriction is due to a morbid growth, palpation, inspection, and percussion of the abdomen may afford valu- able evidence. In making a diagnosis of high stricture I would recommend the following procedures : 1. Obtain a history of the subjective symptoms, such as constipation, diarrhea, pain in the left side of the abdomen, loins, and thighs. 2. An examination of the feces for streaks of blood or slime. 3. Inspection, palpation, and percussion of the abdomen for tumor or fecal impaction in the colon. 4. Examination with the finger under anesthesia, aided by an assist- ant pushing against the examiner's elbow to raise the perineum. 5. The insertion of bougies. The best instrument is hollow, and to its lower end should be fitted the tubes of a fountain syringe or irri- gator containing warm sterilized Avater. The bougie must be inserted with the greatest gentleness, and as soon as resistance is felt the water should be allowed to flow and distend that portion of the bowel. This will dispose of folds of mucous membrane which are so ready to obstruct the tube. In order to pass the promontory of the sacrum the bougie requires to be flexible. 6. Failing in making a diagnosis by any of the preceding, the hand may be pressed into the rectum under the restrictions already men- tioned. 344 SURGICAL DIAGNOSIS AND TREATMENT.

Glands not involved. The sacral lymphatic glands can sometimes be felt through the rectum to be enlarged and hard. Treatment. — The diet of the patient requires careful attention. It should be nutritious, containing such articles as leave a small residue. The feces should be kept soft. When the stricture is due to syphilis or tuberculosis the general treatment of these diseases must be employed. The local treatment of stricture must depend upon the variety. Many annular strictures can be completely cured, while tub- ular strictures are frequently beyond the reach of local treatment. The operative treatment may be considered under the following heads : {a) Gradual Dilatation. — Bougies have been so much abused that it is difficult to estimate their proper value. When they are employed to overcome a stricture it should be clearly understood by both patient and surgeon that a long course of treatment will be necessary. With- out this understanding it is useless to begin. An annular stricture may be compared to a rubber ring. The passage of a bougie will dilate the ring, but it speedily returns to its original size. The use of the instru- ment daily for weeks, and even months, will, however, in many cases finally overcome the elasticity and cause the stricture to disappear. This little operation is very simply done, and especially in stricture low down the patient or a nurse with very little instruction can attend to the treatment. Great care should be taken to make sure that the instrument really passes through the stricture. Sometimes a pouch forms below the stricture, and into this the nurse, or even the physician, has been known to pass a bougie daily for weeks in the belief that he was dilating the stricture. Half an hour before using bougies it is best to give the patient an enema of warm oil and water, which not only empties the bowel, but quiets the irritability of the sphincter (Cripps). The patient lies on his side with one knee drawn up. Beginning with a size which easily passes through the stricture, larger instruments are employed as dilata- tion advances. Great benefit is obtained by keeping the instrument in position from a few minutes to several hours a day as the patient can bear it. INJURIES AND DISEASES OF THE DIGESTIVE SYSTEM. 345 {p) Forcible Dilatation. — This method is attended with too much risk to warrant a recommendation. A stricture when forcibly dilated gives way at its weakest point, and that is usually Douglas's cul-de-sac. The consequence of such an accident is the pouring of the fecal con- tents of the bowel into the peritoneal cavity, followed by general peritonitis and death. So great is the risk of rupture that in no case should an attempt be made to force the finger through a tight stricture for the purpose of ascertaining the condition of the bowel higher up. The only strictures of the rectum in which forcible dilatation can be at all warranted are those within an inch of the anal margin. (r) Litcrnal Division. — This is another dangerous operation. An incision in the rectum is almost sure to result in suppuration, with formation of abscess and burrowing of pus in various directions. The cause of this is readily explained. The sphincter ani closes with more or less accuracy the lower end of the rectum, and acts as a barrier to the downward pressure of the bowel-contents. Before the resistance of the sphincter can be overcome the rectum is distended, and with the distention a stretching of the incision. This not only prevents heal- ing but allows fecal matter to get into the incision and produce sup- puration. id') Posterior Division of the Stricture and External Parts. — The great objection to internal division is the impossibility of free drainage. That objection is overcome when a free division is made, not only of the stricture, but of all the tissues between it and the surface. Operation. — The bowels having been thoroughly evacuated by a cathartic followed by an enema, the patient is placed in the lithotomy position. The finger of the left hand is pressed through the stricture. If this is impossible, a probe-pointed bistoury is passed through, and, its edge being directed backward, the stricture is cut exactly in the middle line sufficiently to allow the finger to pass through. A long curved, sharp-pointed bistoury, guarded by the finger-nail or a director, is then passed through the stricture ; the point is directed backward in the middle line, and made to transfix the rectal wall behind, coming out at the end or side of the coccyx. It is then made to cut its way out. Bleeding points are ligated as far as possible. A drainage-tube is placed in the rectum, its upper end reaching beyond the seat of the operation. Around the tube the space is packed with iodoform gauze and a T-bandage applied. The packing is removed daily, the parts irrigated, and again packed. About the tenth day bougies are passed to prevent recurrence of the stricture, and this is continued for six months. During the healing a full-sized bougie should be kept in for several hours a day. {e) Colostomy. — When other measures are unavailing relief from suffering and prolongation of life can be obtained by the formation of an artificial opening in the colon (see Colostomy). Congenital Malformations of the Rectum and Anus. — These malformations are the result of arrested development in early fetal life. The bowel and the sinus from which are later developed the genital organs are not at first separate in the fetus. If the opening between the two persists, malformation is the result, and the feces may pass by the urethra (Fig. 151), or vagina, or the bladder (Fig. 152), 346 SURGICAL DIAGNOSIS AND TREATMENT. If not wholly absent, the rectum and anus may be very narrow,. though not entirely occluded. Fig. 151. — Imperforate anus, the rectum terminating in the urethra (Gant). Imperforate rectum and imperforate anus are the most common deformities. The bowel is developed from the hypoblast, except the lower por- FlG. 152. — Imperforate anus, the rectum ter- minating in the bladder (Gant).

As the fetus develops the bowel pushes its length dow^nward, and the THE GENITO-URINARY SYSTEM. 347 involution proceeds upward from the surface to meet it. Absorption of intervening tissue takes place, and the two become one continuous passage. If development is arrested at any point, imperforate rectum or anus, or both, may occur. Should the involution at the surface not begin at all, or cease after a mere depression has taken place, the con- dition is known as imperforate anus. The involution, on the other hand, may proceed to a normal exent, but, the bowel not descending sufficiently, absorption of intervening tissue may not take place, producing a condition known as imperforate rectum. All degrees of malformation may exist — from that in which only a thin membrane lies between the rectum and anus (Fig. 153) to those in which, by absence or obliteration of the rectum, there is a space of several inches between the anus and the bowel. Symptoms. — The diagnosis of these conditions is made from the fact that the child has had no motion from the bowels, or by the pres- ence of a fistula connecting the bowel with the bladder or urethra or vagina, through which the feces are passed. In addition, the abdomen is distended, and there may be vomiting severe and persistent. Treatment. — If only a membrane separate the rectum and anus (Fig. 153), a simple incision affords an opening. During the process of healing care must be taken to prevent contraction by daily insertion of the finger. If the rectal pouch is situated high up, but low enough, so that bulging can be detected, an incision should be made in the median line. All tissues are dissected away until the pouch is reached. It should be opened, emptied, cleansed antiseptically, and its edges sutured to the edges of the incision. It is then dressed antiseptically, and bougies inserted daily to prevent contraction. If no pouch can be detected, an incision is made in the left inguinal region, and search made for the end of the bowel and inguinal colostomy performed. When the opening is into the urethra or vagina this fistula should be closed, and an outlet established at the anus if possible ; otherwise, in the left inguinal region, as in high imperforate rectum. CHAPTER VII. THE GENITO=URINARY 5YSTEM. I. INJURIES AND DISEASES OF THE KIDNEYS. Surgical Anatomy. — The kidneys lie behind the peritoneum deep in the lumbar region and imbedded in abundance of loose fatty tissue. Each kidney lies upon the posterior portion of the diaphragm, the transversalis aponeurosis, and the psoas muscle. The upper end of the right kidney is in contact with the under surface of the liver. In front the anterior surface is in relation with the duodenum and the right flexure of the colon. The upper end of the left kidney is in contact with the stomach ; its outer border for two-thirds of its length touches 348 SURGICAL DIAGNOSIS AND TREATMENT. the spleen, and its lower end is crossed by the descending colon ; in front toward the inside lies the pancreas. The upper end of the kidney corresponds with the left intercostal space, and the lower end is on a level with the middle of the third lumbar spine. The right is a little lower than the left, owing to the pressure of the liver from above. The left kidney may occupy a position above the spleen. It some- times happens that there is only one kidney. In this case the organ is large enough to compensate for the absent one. Sometimes both organs are closely united at their extremities, forming the " horseshoe " kidney, so called. The kidneys are subject to great variations both in regard to the size and the position of the organs. They may be placed as low down as the brim of the pelvis or even in the pelvic cavity, and in either of these situations they are likely to give considerable trouble during menstruation or in the progress of parturition. The vessels may also be abnormal. Thus the organ may receive its arterial supply from a vessel rising from the aorta higher up or lower down than in the nor- mal condition, or springing from the common iliac. The ureter is just as variable. Sometimes it is double either at its origin or in its whole course, or it may be tortuous, especially when encroached upon by morbid growths. The ureters lie obliquely, and in such a position that if their axes were prolonged upward they would meet on the ninth dorsal vertebra, and if prolonged downward would pass over the tips of the iliac crests. The inner border of each kidney is con- cave, forming a longitudinal gap called the hilum, which contains three very important structures — viz. the renal artery, the renal vein, and the ureter. These constitute the pedicle in removal of the kidney. The arteries arise from the aorta about the level of the first lumbar vertebra, and pass almost horizontally to the kidneys. The right ves- sel takes a slightly upward course to reach its organ ; it passes behind the inferior vena cava, and is of course longer than its fellow, for the aorta has the vena cava between it and the right kidney. The left artery generally rises a little higher up than the right. Before reach- ing the hilum each arter}' divides into three, four, or five branches which go to supply the renal tissue. The position of the structures at the hilum are, from above downward and backward, artery, vein, ureter. The renal veins pass at right angles from the hilum of each kidney to enter the vena cava inferior. The left vein is slightly higher and longer than the right. The ureter is the membranous tube which con- veys the urine from the kidney to the bladder. It is about fourteen inches in length and its diameter is about one-eighth of an inch. It begins at the lower border of the kidney, and expands into a funnel- shaped sac called the pelvis ; then passes down behind the peritoneum lying upon the psoas muscle, and crosses the bifurcation of the common iliac artery to reach the base of the bladder. Following the ureter from the pelvis into the substance of the kid- ney, we find that it divides into two or three short trunks, and these again subdivide to form the primary tubes or infundibula which receive the papillae. The kidney is held in position by a mass of fat which forms its bed. In this it enjoys a slight degree of mobility, and when the fat is opened THE GENITO-URINARY SYSTEM. 349 up the kidney may be seen to rise and fall with respiration. Sometimes this fatty capsule is wanting, and the organ is held in place only by the blood-vessels and ureter at its hilum, or, the fat being lost by sudden emaciation of the patient, the movements of the kidney are greatly increased. To this condition the name " movable kidney " is applied. Sometimes the peritoneum invests the organ, forming a mesonephron, and the kidney becomes displaced into the general peritoneal cavity, moving freely in every direction as far as its vessels and ureter will permit. To this abnormality the name of" floating kidney " is applied. Injuries of the Kidney. The kidneys are well out of harm's way, being protected in the rear by the strong, thick muscles of the lumbar region, and in front by the abdominal wall and the abdominal viscera. Injuries of the kidney are on this account comparatively rare. They may be divided into three classes : I . Contusion without I/aceration of the External Tissues. — This is one of the most frequent of renal injuries. It may be pro- duced by blows or falls, especially when the body is in a sitting posi- tion or forcibly bent forward at the time of striking the ground. Another common cause of renal contusion is a squeezing or crushing of the loins between carriage or machine wheels. Whatever the cause, it may produce injury varying from little discomfort and few symptoms up to complete rupture and even pulpification of the organ. Trauma- tisms in the renal region, according to Kiister, cause either laceration of renal tissue or mobility of the organ. As a rule, laceration occurs in males, mobility in females. This is accounted for by the fact that in the female the conformation of the body, the thickness of the adipose tissue, and the protection afforded by the corset break the direct force of a blow, and thus guard against lacerations.^ Synipt07iis. — The violence which produces the kidney lesion is likely to cause so much pain in the loin as to mask the symptoms which point more directly to the kidney. The pain shoots down the thigh and into the testicle and loin. If the kidney is injured, we have in addition fre- quent micturition and sometimes hematuria. Blood in the urine, how- ever, is a symptom that must be carefully weighed. It may be present when there is sudden congestion in any portion of the urinary tract, as in violent strains. On the other hand, there may be extensive lacera- tion and hemorrhage from the kidney, but, owing to the formation of a clot in the ureter, no blood escapes with the urine. The quantity of the blood that escapes is very variable. When it is extravasated around the kidney it causes swelling in the loin, and as the blood-stained serum passes downward along the vessels the skin becomes discolored in the inguinal region, in the scrotum, and in the thigh. When only the cortex of the kidney is torn the hemorrhage is usually slight. If the laceration extends into the hilum or a vessel of considerable size is torn, then a profuse flow of blood runs down the ureter, filling the bladder, and perhaps coagulating therein. The symp- ^ An7i. of Univ. Med. Set., 1S96. 350 SURGICAL DIAGNOSIS AND TREATMENT. toms of renal colic follow, and in some cases long worm-like clots are expelled per urethram. There is intense pain about the pubes and at the end of the penis. If the ureter becomes completely occluded by a clot, hydronephrosis follows. Still more copious is the loss of blood when the peritoneum is ruptured and the hemorrhage is poured out into the abdominal cavity. The symptoms of profuse hemorrhage rapidly come on and the patient may bleed to death in a short time. Extravasation of Jiri/ic from the kidiuy is a symptom which is of rare occurrence. It does not take place unless the pelvis or the hilum is ruptured. Then the urine is poured out either into the peritoneal cavity or into the areolar tissue around the kidney. Inflammation follows, and often results in suppuration and sloughing, to which the patient eventually succumbs. Trcatinciit. — The patient should be kept in the recumbent posture and fed on liquids. The loins should be supported by a broad strip of adhesive plaster, as in the treatment of fractured ribs. Gallic acid, ergot, acetate of lead, and opium are valuable in checking hematuria. The bowels can be relieved by enemata, but purgatives are to be avoided. When the bladder is filled with blood, as evidenced by tenesmus and the passage of clots, every care must be taken to prevent cystitis. A double-current catheter should be inserted and irrigation carried out with some mild disinfecting fluid, as boric acid or Thiersch's solution ; or one of the evacuating tubes and evacuators used in lithot- rity can be employed to throw in and w^ithdraw quantities of water from the bladder. When the coagula are so large and firm as to resist these methods perineal section is indicated. Severe cases w^iich are attended with profound shock and a rapidly increasing tumor in the loin demand a lumbar incision. After exposing the kidney the bleeding points are sought for and ligated ; if the kidney is disorganized, it should be removed. 2. Wound of the Kidney with I/aceration of the External Parts. — The anterior surface of the kidney may be penetrated by an instrument or missile entering the abdomen and passing through both layers of peritoneum. The symptoms in this case are those of hemor- rhage or extravasation of urine into the peritoneal cavity. When the wound is received in the loin, the posterior surface of the kidney is the part to suffer. If urine escapes, it is proof positive of renal lacera- tion, but it must be remembered that the cortex may be incised with- out flow^ of urine. Hematuria is also a sign, but the same uncertainty attends it here as in the preceding class of injuries. Perinephric abscess is a frequent sequel of renal wound. Extra-peritoneal wounds gen- erally do well, but those which are intra-peritoneal have a very high mortality. Treatment. — Wounds of the kidney inflicted through the loin are extra-peritoneal and require the same treatment as nephrotomy. A drainage-tube is inserted down to the wound in the kidney, and the surrounding space packed with strips of iodoform gauze. Should further drainage be required, the external wound should be enlarged. 3. Intra-peritoneal wounds of the kidney demand celiotomy, and in most instances nephrectomy. THE GENITO- URINAR Y S YSTEM. 3 5 I Diseases of the Kidney. Bxamination of the Kidneys. — In the injuries which have just been described our attention is naturally directed to the kidneys by the position of the traumatism and the nature of the accident. In surgical diseases of these organs we are led to the kidneys by the general examination of the patient. When, for instance, we get a history of violent attacks of pain in the loin shooting down toward the bladder, the testicle, and the thigh, we suspect renal calculus, and the suspicion grows upon us if we learn that during or after these attacks small quantities of bright-red blood have come away with the urine. Again, if the patient complains of periodical attacks of violent pain with marked diminution of the quantity of urine, followed by a copious flow and relief of all symptoms, we suspect hydronephrosis due to movable kidney, and our suspicion is confirmed if he also tells us that a tumor of a somewhat erratic character can be felt from time to time. In the examination of the kidney our methods of investigation are somewhat limited. Inspection is only of value when the loin is greatly distended by a solid or cystic tumor, in cases of hydronephrosis or pyonephrosis, in enlargement of the kidney, and in cases of hemorrhage which is extra- peritoneal. Palpation is often of great value. The healthy kidney of normal size and lying in its proper position is beyond the reach of palpation. It is only when the organ is enlarged that it can be felt. To examine it by palpation place the fingers of one hand just below the twelfth rib and at the outer edge of the erector spinae muscle, or about two and a half inches from the spinous processes ; the other hand is placed on the abdominal wall in front. The enlarged kidney can be felt between the two hands. Sometimes the finger and thumb of one hand are sufficient, and in this way a good idea of the size of the kidney can be obtained. In very lean persons with lax and thin abdominal walls the lower third of the kidney may be felt ; with this exception, if you feel the kidney at all, you may set it down as an enlargement of the organ. As the kidney enlarges it extends in two directions, downward and forward. The ribs and spinal column prevent its extension backward, and its own weight tends to drag it downward. Hence the greater the enlargement the more easily can the kidney be palpated. Israel's method of palpation is as follows : A line parallel with the middle line of the abdomen is drawn from the middle of Poupart's ligament to the margin of the ribs. The finger-tips, placed two finger- breadths below the margin of the ribs and upon this line, are directly over the lower extremity of a kidney in place. In order to feel this kidney we must avoid poking with eager hooked fingers, or the abdominal muscles will contract in resentment. The tips of the straight-extended fingers are placed upon the point indicated while the patient lies supine, with flexed legs, upon a hard bed or table; The other hand now lifts the loin gently toward the opposed fingers. At each expiration which the patient makes the fingers upon the abdomen are pressed a little farther toward the kidney ; the impress-fingers easily recognize the object sought for. If the patient now takes a full breath. 352 SURGICAL DIAGNOSIS AND TREATMENT. a wandering kidney will be forced far under the finger-tips (Israel, cited by Fenwick). Percussion. — The solid structures which surround the kidney render its percussion impossible. On the right side the liver, on the left the spleen, form its upper boundary ; behind is the spine, over it the muscles, and surrounding it a mass of adipose tissue. There is therefore nothing resonant about the kidney on any side. Only when the organ is greatly enlarged can we gain anything from percussion, and then it simply confirms what we have learned by palpation. Some- times a resonant area traverses a greatly enlarged kidney ; tJiis is the distended eolon. Exploratory puncture is valuable, and, as it is extra-peritoneal, the danger attending its employment is less than in abdominal explorations. In hydronephrosis and pyonephrosis the needle is of great value, for, having established the diagnosis, it can be used to evacuate the fluid and thus produce relief, possibly a cure. Movable Kidney. — Care should be taken to avoid the common error of confusing the terms movable kidney and floating kidney. Movable kidney is an acquired condition in which the organ remains behind the peritoneum, but with more or less movement. It is simply loosened up in its fatty bed. Floating kidney, on the other hand, is a congenital abnormality in which the peritoneum surrounds the kidney forming a renal mesentery. The kidney in this case has no fatty bed, but floats about the abdominal cavity as far as its mesentery will permit. Movable kidney is more common on the right side than on the left, and this has been accounted for by the downward pressure of the liver. Women suffer more frequently than men, for the reason that repeated childbearing, with its alternate distention and relaxation of the ab- dominal wall and sudden loss of the fatty tissues of the body, is a prominent cause of renal displacement. Symptoms. — The sufferings of the patient depend to a great extent upon the degree of mobility of the kidney. There may be only slight discomfort or there may be the most agonizing pain. When there is slight mobility, discomfort is usually felt after exercise, and especially after long walks, or rides in which there is much jolting. The menstrual period seems to have a powerful effect in bringing on pain. There is a sense of dragging in the loin, and the pain shoots down the groin and the thigh, as it always does when the kidney is the seat of irritation. Very serious and alarming symptoms set in when the kidney turns over in such a way as to twist its pedicle and cause obstruction in the ureter and the renal vessels. The urine, no longer allowed to flow away, distends the kidney, producing the condition known as hydro- nephrosis. W'hen we stop to consider the disturbances which would naturally be caused by a kidney distended almost to bursting by the pent-up urine, we can readily understand the remaining symptoms. The flow of urine from the bladder is diminished. Resorption of urea takes place, and there are headache, stupor, foul tongue, vomiting, and sometimes jaundice. In nearly all cases of movable kidney the patients are nervous and hysterical. Dyspepsia, loss of appetite, and general debility are always present. On palpation, with one hand at THE GENITO-URINARY SYSTEM. 353 the outer border of the erector spinae muscle and the other in front, the kidney may be felt. Sometimes it is difficult to find it, and the patient should be placed upon his hands and knees, in which position the kidney falls forward upon the palpating fingers. Some patients have a way of assuming positions which bring the wandering organ into prominence, and I am in the habit of giving them an opportunity of doing so. In favorable cases a tumor can be felt which is of the shape, size, and consistency of a kidney. It is freely movable over a certain area, but returns naturally to the normal position of the kidney in the loin. Sometimes the organ can be grasped between the thumb and fingers of one hand and made to slip from place to place. The mobility of the kidney may give one loin a want of resistance in comparison with the other. Pressure applied to the kidney causes a sickening pain very similar to that felt in the testicle or ovary, and when this can be elicited in a movable tumor it is strongly confirmator}^ of a wandering kidney. The failure to find a movable tumor by palpation must not be taken as settling the question. If the other symptoms are present and constant, and if they are breaking down the patient's health, operative procedure is indicated. Diagnosis. — Many other tumors are liable to be mistaken for mov- able kidney, but it is seldom that a movable kidney is mistaken for anything else. The history of the case, the position of the tumor, its tendency to return to the loin after it has been pushed to the length of its tether, and a careful study of the symptoms must be our safeguard. Floating kidney cannot be positively distinguished from movable kid- ney by any symptom yet known. The length to which a mesonephron permits the kidney to wander has been supposed to afford a criterion, but when a movable kidney has become so loose that its movement is only restricted by the renal vessels and the ureter, it has every charac- teristic of a floating kidney. Treatment. — Inasmuch as exercise and jolting of the body increase the suffering, the patient should be kept as quiet as possible. In mild cases patients may experience great relief by wearing an elastic belt with an air-pad so constructed as to push the kidney well back into the loin. When the cause of mobility is the loss of fat, as in women who have undergone rapid emaciation, an attempt should be made to restore normal conditions by keeping the patient in bed and on a diet which will produce the greatest amount of fat. The most troublesome cases are those in which renal colic occurs from twisting of the pedicle. During an attack perfect quiet in the dorsal position must be enjoined, with hot fomentations and sedatives to relieve pain. Such cases are not infrequently attended with degenerative changes in the kidney itself, and thus the condition is rendered more serious. When ordinary means fail, relief must be sought by operation. The operation by which a movable kidney is made to form attach- ments in its original position is called nephrorrhaphy {yzippoz, a kidney ; ^«^7^, a suture). A better word would be nephropexy {yecpb:;, a kidney ; -rjyuoixc, I fix). The mortality of the operation is probably not more than 2 per cent., but the results are not always satisfactory. The patient is placed on the sound side with a firm round sand-bag or 23 354 SURGICAL DIAGNOSIS AND IIUiATMENT. pillow under the body to increase the costo-iliac space as much as pos- sible. The incision is made in the loin, and is practically the same as that eniplo\-ed in lumbar colotomy, only about an inch farther back. Its bei^innini^ is at the lower border of the twelfth rib and at the outer border of the erector spinas muscle. This point is generally about two and a half inches from the spinous processes of the vertebrjE. From this, as a starting-point, the incision is carried downward and outward toward the crest of the ilium for three inches or more. The skin and fat are divided and any bleeding points secured. The super- ficial fascia is next laid open to the full extent of the wound, exposing the outer edge of the latissimus dorsi and the posterior border of the external oblique. Broad retractors in the hands of an assistant hold the edges of the wound apart and afford working space. The edges of these muscles are divided with scissors and the internal oblique and transversalis come into view. These in their turn are severed as far as the upper and lower limits of the skin-wound, and lastly the deep layer of the lumbar aponeurosis. The peritoneal fat is now seen bulging up into the wound, and it is an easy matter to tear it apart with scissors and expose the kidney itself To bring the kidney up to position an assistant with strength and endurance in his arm pushes it from the front. In all operations on the kidney the organ gradually comes up into the wound by internal abdominal pressure, so that, although it may seem very far away when first exposed, it comes nearer and nearer to the surface and can soon be conveniently handled. Having exposed the kidney, two fingers are passed around the cap- sule to ascertain the condition which is the cause of the mobility. By tearing the fatty tissue and irritating the fibrous capsule, either by manipulation or by scratching with the point of a needle, adhesive inflammation will be induced, and upon this our chief reliance must be placed. The renal capsule is opened and stripped off for a short distance, so as to expose a raw surface of kidney. Sutures are then passed through the lumbar aponeurosis, the capsule, and the border of the kidney-substance. Some surgeons fasten the kidney to the twelfth rib, and with a show of reason, for when the organ is hardened ill situ it bears a deep groove, which is the impression of the twelfth rib, and shows that in normal conditions the kidney lies in contact with that bone. Chromicized catgut is a suitable material. Its service is but temporary, for it only keeps the parts in apposition while adhesive inflammation is taking place. Three or four sutures are sufficient. A drainage-tube or strip of iodoform gauze is next placed in the wound with its inner extremity touching the kidney. The wound is closed with silkworm gut and a full dressing applied. The patient should lie on the back as much as possible, in order that the kidney may not gravitate from its position, and should keep his bed for six weeks. Nephrectomy has been resorted to for the worst forms of movable kidney. It is only when the organ is diseased as well as distressingly movable that such a procedure is warrantable. Renal Calculus. — Stones are formed in the kidney by the aggre- gation and consolidation of certain constituents of the urine which under normal conditions the kidneys eliminate. Of this class the most common are uric acid and oxalate of lime. In unhealthy conditions THE GENITO-URINARY SYSTEM. 355 of the urine, and especially when it undergoes decomposition, a pre- cipitation takes place which may result in the formation of stone. The constituents in this class of cases are most commonly phosphate of lime and the ammonio-magnesium phosphate. Renal calculi vary greatly in size, number, and shape. Frequently they are round, and so small and smooth that they pass with ease through the ureter and are voided in the urine. Others are rough and pointed with crystals, so that on their passage they lacerate the deli- cate lining of the urinary passages and cause it to bleed. Others are so large that they cannot pass away from the kidney, but, continuing to increase in size, produce one of the most distressing conditions which a human being can be called upon to endure — exciting inflam- mation, stopping the flow of urine, and bringing about the destruction of the kidney itself Symptoms. — The symptoms of renal calculus are practically those of a foreign body in the kidney. Depending upon the position of the stone and other circumstances, these symptoms are subject to consider- able variation. They are not usually all present in any given case, but the cardinal signs are not often wanting. These are pain and hematuria. I. Pai)2. — Two kinds of pain are recognized, direct and reflex. Direct pain may be constantly felt in the region of the kidney or it may only be present when the patient is in active exercise. Movement and jolting always aggravate it. When pressure is made over the kid- ney or the organ grasped by the hands in the loin the tenderness is very great. It may be that no other symptoms are manifested, and yet a diag- nosis of stone is warranted, and it may further be assumed that the calculus is either in the cortical substance or in some part of the kidney in which it cannot move. Very different is the character of the suffering when the calculus rolls about in the pelvis of the kidney, becomes blocked in the ureter, or performs its painful journey to the bladder. Renal colic is the name applied to these attacks when they appear in their worst form. The local pain is intense, and the patient clutches the affected loin as if to pluck some cruel dart from his tortured flesh. He rolls from side to side bathed in perspiration ; rigors are frequent, and vomiting is often severe and persistent. There are frequent calls to micturate, but the quantity of urine is small. All this time the stone is working its way down the slender ureter, rasping, scratching, and tearing the delicate lining and causing more or less blood to flow. At last, after a couple of hours or it may be several days, the calculus drops from the ureter into the bladder. If it be true, as stated by some old philosopher, that " the height of happiness is relief from pain," the patient expe- riences real happiness, for the pain suddenly ceases and a great calm follows the storm. But a well-marked attack of renal colic may occur and no stone pass into the bladder. The concretion may get into the very beginning of the ureter, where the tube is larger than elsewhere ; it goes far enough to produce occlusion ; the urine collects behind it, producing hydronephrosis ; after a time the stone drops back into the renal pelvis and the pain subsides. 356 SURGICAL DIAGNOSIS AND TREATMENT. Reflex pain is felt at a distance from the seat of trouble. It runs to the loin and the testicle, causing the latter to be drawn strongly upward. It runs down the thigh along the inner side, and even extends to the leg. Sometimes the patient traces a line along which he says the pain is intensified, and this line corresponds with the course of the ureter. It must be carefully borne in mind that stone in one kidney may cause pain in the opposite organ. Indeed, cases are on record in which all the symptoms were on the side opposite to the disease. 2. Blood in the Jirinc is the second cardinal symptom. An attack of renal colic followed by hematuria is almost pathognomonic of renal calculus. The blood may appear in the form of small rounded clots or it may be mixed with the urine less intimately than in other renal dis- eases, but more freely than when the blood comes from the bladder or prostate. Hematuria may be absent from first to last. When the urine con- tains blood, it of course gives the test for albumin. There are cases in which albuminuria exists without the presence of blood. Pus is frequently found in the urine of persons suffering from stone in the kidney. It is a symptom of great gravity. It proves that inflammation has gone on to suppuration, and that destruction of kidney-tissue is taking place which may result in complete disorganiza- tion. Mucus in the urine is also an important symptom. It is of special significance in young persons, who are not likely to suffer from enlarged prostate. In the majority of cases the diagnosis of stone in the kidney is not difficult. The most fruitful source of error is stone in the gall-bladder. It is remarkable how silent the text-books are upon this point, and yet there are cases in which a positive diagnosis is impossible. (See Diag- nosis of Gall-stones.) The differentiation must rest upon two points : I. A microscopical examination of the urine, which in the case of renal calculi will almost surely contain blood- or pus-corpuscles. 2. Tender- ness over the kidney. Another condition simulating in some degree the passage of renal calculi is the discharge of tubercular abscess from the kidney to the bladder by way of the ureter. Considerable pain may be experienced and the symptoms closely resemble renal colic. In gouty persons a discharge of large quantities of crystalline uric acid may simulate calculus, but in either of the above the history will generally remove all doubt. The ;i--rays have been successfully employed in a number of cases. In one case which came under my observation they proved misleading; the skiagraph seemed to reveal a stone, but on operation nothing but a healthy kidney was found. Commencing tuberculosis in the kidney may lead us into error. The symptoms already laid down and the examination of the urine for the tubercle bacilli will generally settle the question. The pathological condition and the size and position of the stone may in many cases be diagnosticated. When pain and hematuria are the only symptoms, we may assume that the kidney is Jicalthy and the calculus large. When there are pus in the urine, a swelling or increased resistance in the loin, and tenderness over the kidney, an abscess with THE GENITO-URINARY SYSTEM. 357 small calculus may be diagnosed. Hydronephrosis, as evidenced by a swelling in the loin, which is not tender to pressure and not very hard, accompanied by alkaline urine, little pus, and repeated attacks of renal colic, points to a stouc that is blocking the uj'ctcr. Treatment. — During attacks of renal colic pain should be relieved by hypodermic injections of morphin and the application of heat to the loin. It is possible to aid the expulsion of a small stone by giving the patient bland fluids in abundance to flush the urinary tract. These measures, however, will in the great majority of cases be of little or no avail, and considering the stone as a foreign body, the only hope of permanent benefit lies in its removal. Indicatitvis for Operation. — Not every renal calculus requires an operation. If the stone is lying quietly in its bed, producing no pain and causing no serious mischief, it should be let alone. When attacks of renal colic follow closely upon each other, making the patient's life a burden and preventing him from following his occupation, then an operation is clearly indicated. Even if the diagnosis be shrouded in more or less doubt, an incision for exploratory purposes should be undertaken. Operation. — For the operation of nephro-lithotomy the incision is the same as that described under Nephrorrhaphy. When the kidney is exposed the finger should be passed over its surface both before and behind in search of inequalities which would indicate the presence of a stone, a collection of fluid, a new growth, or abnormal mobility of the organ. Failing to find evidence of a calculus by digital examination, a fine aspirating needle can be used with the view of searching for stone or of finding a cavity containing pus or other fluid. As a means for finding stone I am convinced that punctures with a needle are of very little value. In one case I passed a needle in about a dozen places without feeling the least sensation of the instrument touching a stone, and yet when I laid the kidney open forty small stones were removed. Influenced by this and several similar experiences, I have come to the conclusion that when digital examination fails to find a stone the next step should be to lay the kidney open. By such an incision an abscess can be evacuated or a stone in the pelvis of the kidney exposed. The opening should be made on the convex surface of the kidney and large enough to admit the fore finger. If no stone can be felt by the finger in the pelvis of the kidney, a uterine probe bent so as to form a short- beaked sound is employed to search the calyces. A flexible probe can be passed down the ureter to the bladder. When a stone is found it is removed by forceps. If the calculus be branched so as to fill a number of the calyces, it may be necessary to break it into fragments before removal. These cases are often exceedingly troublesome, and require the utmost perseverance and ingenuity of the surgeon. Having gotten rid of the stone, a drainage-tube is introduced down to the opening in the kidney. Around the tube is placed a packing of iodoform gauze, the wound in the loin is closed except at the point of exit of the tube, and a dressing applied. Nephrectomy (removal of the kidney) is indicated when the organ is so disorganized by the presence of stones or from any other cause that it cannot return to its normal condition. When calculi are found 358 SURGICAL DIAGNOSIS AND TREATMENT. imbedded in abscess-cavities this question must be considered, for it is better to remove a kidney that is riddled with abscesses than to let it remain with the certainty of a second operation later on. To remove a kidney is a serious consideration. The question of throwing the whole of the work on one kidney is by no means the most serious problem involved. If the remaining; or<^an be healthy, it is probably already doing its own work and that of its fellow. In a case of nephrectomy for chronic abscesses I found that the patient was voiding thirty-one ounces of urine daily ; in the twenty- four hours following the operation it amounted to twenty-nine ounces ; and at the end of three or four days it was restored to the normal quantity. A much more serious question is the possibility of there being only one kidney. In one out of every four thousand persons all the renal substance is enclosed within one capsule, the removal of which would leave no kidney at all. Another consideration is the possibility that both kidneys are diseased. Assuming that one kidney is so seriously diseased as to warrant its removal, the state of the other organ must be systematically examined. A good routine method of investigation is the following : 1. Examine the organ by inspection, palpation, and percussion. 2. By repeated examinations of the urine satisfy yourself that a normal quantity and quality is being voided. The quantity of urea should be carefully noted. 3. Examine the interior of the bladder with the cystoscope. The pumping action of the ureters can in this way be brought under obser- vation, and the appearance of the urine as it escapes from each ureter can be studied. 4. In the female the ureters should be catheterized. (See Cystos- copy.) The operation of nephrectomy is thus performed : The incision is the same as for nephrorrhaphy or nephro-lithotomy. After exposing the kidney the finger is made to pass around it on every side to free the organ from its fatty capsule. It is then very carefully drawn into the wound as far as possible and handed to an assistant. The next step in the operation is to find and secure the pedicle. In this case the pedicle consists of the renal artery and veins and the ureter. The fingers of the operator tease out the fat about the pelvis of the kidney, exposing the vessels. The pulsation in the renal artery is a guide of great value. Two ligatures are necessary — one for the vessels, the other for the ureter. A pedicle-needle armed with a stout silk thread is made to surround the vessels which form the upper part of the pedicle. The ligature is then tied, care being taken that during the tightening the assistant relaxes the traction on the kidney. The ureter is then isolated and clamped with a pair of forceps as a temporary measure. The kidney is now cut away. To be on the safe side against cutting too closely to the ligature, a strong pair of forceps may be placed upon the pedicle between the ligature and the kidney. By cutting on the outside of the forceps ample space will be given to prevent slipping of the ligature. We must relax tension on the THE GENITO-URINARY SYSTEM. 359 pedicle while the ligature is applied ; we must be equally careful to do the same thing while the pedicle is being divided, for an arter>^ put on the stretch at this critical juncture might retract beyond the ligature and produce fatal hemorrhage. The kidney disposed of, attention is now turned to the ureter which was left secured by a clamp-forceps. If there is no thickening of the walls of the duct, it can be secured by a strong silk ligature and dropped into the cavity. If there is much thickening or ulceration in its walls, it is best to attach it to the parietal wound. In the case of a large suppurating kidney there may be no room for the application of a ligature between the aorta or vena cava and the kidney. A temporary elastic ligature can then be thrown around the base of the kidney and the diseased organ cut away with scissors. This will do away with the risk of making too great traction on the pedicle, and by cutting it away in pieces will allow a greatly enlarged kidney to be delivered through the parietal wound. As soon as the kidney is removed the pedicle is secured by ligatures, forceps, or actual cautery and the elastic band removed. If there is any apprehension of hemorrhage, strong forceps can be applied to the pedicle and left in position for thirty-six hours. They serve an excellent purpose in the way of drainage. The external wound is stitched with silkworm gut and a full absorbent dressing packed around the forceps. When the forceps are not loft in the wound, a full-sized drainage- tube is inserted and the opening closed and dressed as in the pre- ceding operations. Abdominal nephrectomy is rarely indicated. It has one advantage over the lumbar operation, in that the operator can settle the question of the presence and integrity of the opposite kidney. It is more suitable than the lumbar operation for large movable, non-adherent tumors and for a movable kidney which has become diseased and does not admit of lumbar nephrectomy. The incision is made in the linea alba or in the linea semilunaris. The length should in no case be less than four inches, for it will be necessary to admit the whole hand. For the removal of large tumors the incision must be correspondingly extended. The middle of the incision should be on a level with the umbilicus. Having entered the abdominal cavity, the first point to settle is the condition of the other kidney by direct palpation. Satisfied on this point, the peritoneum over the diseased organ is scratched through. This opening must be in the outer layer of the mesocolon. The fingers separate the front of the kidney from its fatty capsule. The pedicle is exposed and one ligature passed around the vessels, while strong forceps secures the ureter. The kidney is then cut away at a safe distance from the ligature, and all bleeding points carefully secured. The ureter is dealt with accord- ing to circumstances. If healthy, it is washed, ligated, and allowed to drop. If suppurating, it can be secured in the parietal wound or brought through an opening in the loin. This will allow of its being irrigated from time to time and will prevent the formation of an abscess. The question of abdominal drainage here is settled by the rules which govern it in other celiotomies. If pus or urine has escaped into the 360 SURGICAL DIAGNOSIS AND TREATMENT. peritoneal cavity during the operation, a drainage-tube should be inserted, otherwise it is not necessar\'. Perinephritic and Nephritic Abscess. — Suppuration occurs around the kidney as a result of direct violence, such as blows or kicks upon the loin. It may be produced by the presence of a renal calculus or it may spread from more distant organs, such as the liver, gall- bladder, spleen, the intestine, or the vertebrae. Urinary fistula and extravasation of urine are also causes. It not infrequently happens that a perinephritic abscess is a metastasis from some distant organ, or it may be a direct migration of septic infection from the urethra or bladder. Symptoms. — The local symptoms of a typical perinephritic abscess are — tenderness in the loin with swelling more or less tense, the swell- ing and tenderness being due to a collection of pus. We naturally look for fluctuation, but, owing to thickness of the overlying tissues, it is generally impossible to find it. To wait for the abscess to come near enough to enable us to find fluctuation would be bad surgery. Much better is it to make an exploratory puncture or incision and settle the question. No harm can come from it, and neglect of this measure may prove disastrous. The general symptoms are those of suppurative inflammation, high temperature, rapid pulse, chills, and general malaise. In the course of time the pus has a tendency to burrow in one of several directions and the symptoms are modified accordingly. It is a rare event for the abscess to rupture into the peritoneal cavity. When this happens the symptoms are those of general peritonitis. The most common directions in which the pus is likely to burrow are the fol- lowing : 1. It is confined by the fascia surrounding the neighboring muscles, and eventually points in the loin. In this case we will have pain, tenderness, swelling, edema, and, at a late stage, fluctuation in the loin. 2. The pus gets into the sheath of the psoas, and, following the course of that muscle, points in the inguinal region after the manner of a psoas abscess. The psoas being involved, we naturally find the muscle contracted. Hence the hip is flexed and the patient is unable to extend the thigh. Pain is felt in the thigh and may run down the obturator nerve to the knee. Reflected pain is felt in the testicle or vulva. 3. The pus burrows upward through the diaphragm, and, pene- trating the lung, is got rid of by expectoration. Here we must be on our guard lest the pleuritic and pulmonary symptoms divert our atten- tion entirely from the kidney. In a case which came under my care in 1 884 a fistulous opening in the fifth interspace on the left side was sup- posed to be due to empyema. On passing a flexible catheter through the opening it took a direction directly downward and was arrested in the loin. Cutting down upon the end of the catheter, the sinus was traced directly to the kidney. Free dilatation and drainage stopped the suppuration. When pus takes this upward course we expect to find pleuritic friction, effusion and empyema, dyspnea and expectoration of pus. On the right side the liver is liable to be involved, hence jaun- dice is a common symptom ; the stomach sympathizes, and there is THE GEAVTO-CNnVARY SYSTEM. 361 vomiting ; pressure interferes with the venous circulation, and there is ascites. In rare cases perinephritic abscesses have burst into the colon, the duodenum, and the bladder. Trcatvioit. — Hot fomentations give temporary relief, but valuable time should not be wasted in employing such reme- dies. The proper treat- ment is to make an incis- ion, wash out the pus, and drain the cavity. The term nephritic ab- scess is to be restricted to a collection of pus in a kidney otherwise healthy. Abscesses of this charac- ter seldom contain more than half an ounce of pus. The tendency is for the pus to find its way into the pelvis of the kidney, thence being expelled with the urine, recovery taking place. The symptoms are usually severe at the out- set of acute cases, while in chronic cases there may be little or no fever. Pain is usually felt in the loin and is intense ; rigors oc- cur at frequent intervals, and the temperature is high. There is a feeling of increased resistance in the loin, and sometimes there are redness and ede- ma of the skin. The urine should be carefully exam- ined for pus ; if it occur in considerable quantity and is followed by diminution of a tumor in the loin, a diagnosis of renal abscess can be made with certainty. Treatment. — I n c i s i o n is the proper treatment. Fig. 154. — Suppuration in right kidney, ureters, blad- der, and prostate from stone in the bladder. The left ureter, filled with water, measured J-i in. in diameter. The capacity of the bladder was only 9 drams. The blad- der contained a calculus i^ in. in diameter (from a photo- graph in the collection of Dr. Jepson, Sioux City, Iowa). Sometimes the pus lies beneath the capsule of the kidney, and a simple incision of the membrane is sufficient. When it lies deeper in the substance of the organ the kidney must be incised and drained. Surgical Kidney. — This is an unfortunate choice of a name, and 362 SURGICAL DIAGNOSIS AXD 71-:EATiMENT. means iiothini:^. It is used to designate a general suppuration in the kidne\' which is secondary to sujjpuration of the urinary tract lower down, as, for instance, in the bladder or urethra (Figs. 154, 155). It was observed to frequently follow surgical operations on these parts, and hence the name " surgical kidney." In reality, it is more fre- FlG. 155. — Left kidney of same case as Fig. 154.

The disease frequently affects both kidneys simultaneously, both being equally exposed to infection. Symptoms. — The patient is usually a sufferer from some chronic urinary disorder, as stricture or enlarged prostate, requiring the fre- quent use of a catheter. The extension of sepsis to the kidney is observed after the employment of catheters or other instruments, but it may be entirely independent of them. At first the symptoms are of a typhoid character. The patient becomes feverish, has a furred tongue, dry skin, foul breath, and is restless and sleepless. Rigors are frequent, sweating profuse, and emaciation becomes marked. The urine generally contains pus and is ammoniacal. Death by exhaustion THE GENITO-URINARY SYSTEM. 363 is the rule, but in some cases suppression of urine, followed by uremia, brings about a painless dissolution. Treatment. — Prevention is better than cure. In every case requiring the use of a catheter or the simplest operative procedure on the ure- thra or bladder the greatest care should be taken to disinfect the seat of operation and the instrument employed. When, after the use of a catheter, symptoms of urethral fever set in, the urine should be dis- infected by the administration of salol or quinin, and the patient kept on nutritious and easily digested food. Should there be evidence of cystitis or an unhealthy condition of the urine, a soft-rubber catheter should be introduced with the least possible irritation and the bladder washed out with boracic-acid solution. When there is suppurative cystitis the bladder should be washed out, and injected with an ounce of water containing three grains of nitrate of silver, after which the bladder should be again irrigated with sterilized water. The question of nephrotomy for surgical kidney is advisable in certain cases. If there be evidence of renal abscess and the condition of the patient will justify it, an exploratory incision should be made over one kidney in the hope of giving exit to an abscess or of checking the septic process by incision and drainage. Hydronephrosis. — The kidney may be compared to a lake among the hills, drawing its water from numberless springs and rills, and hav- ing as its outlet a mountain-stream which bears the surplus water to the sea. If from any cause the outlet becomes obstructed, the lake must overflow. So it is with the kidney when its outlet, the ureter, becomes impervious. The numberless tubules like tiny mountain-rills continue to pour urine into the renal pelvis, from which there is no escape ; the pelvis and calyces expand, eventually forming a tumor in the loin attended with most disagreeable symptoms. It is a serious matter when one kidney is thus affected ; it is disastrous when hydro- nephrosis occurs simultaneously in both. The obstruction which produces this serious condition is congenital in about one-third of the cases. A stone impacted in the ureter is responsible for about 40 per cent, of acute cases, and is one of the serious results of renal calculus. Sometimes the pedicle of a movable kidney becomes twisted and obstruction in the ureter is complete. Growths in the bladder, tumors pressing upon the ureter, enlarged prostate, and pregnancy are also entitled to places on the list of causes. It is a curious fact that frequent micturition of itself is a sufficient cause of hydronephrosis. This is how it happens : Every time the bladder contracts the ends of the ureters which pass obliquely into the bladder are compressed and the flow of urine is obstructed. Stone in the bladder causes oft-repeated contractions and is a common cause of hydronephrosis. SvJnptoins. — There are two leading symptoms of hydronephrosis : I. The formation of a tumor in the loin or abdomen, increasing rapidly and fluctuating. 2. An excessive flow of urine, followed by subsidence of the tumor. This is pathognomonic. It is seldom, however, that these two .symptoms are found together. The tumor, when it is appa- rent, varies greatly in size. In one case examined post-mortem by Glass the right kidney formed a tumor which so distended the abdo- 364 SURGICAL DIAGNOSIS AND TREATMENT. men that it measured six feet four inches in circumference, and from the ensiform cartilage to the pubis it measured four feet and half an inch. The fluid contained in the cystic kidney measured thirty gallons and was of a light coffee-color. The tumor is sometimes irregular or lobulated, and fluctuation may be felt. Without a tumor there are no s\-mptonis which are distinctive of hydronephrosis. Sometimes hydro- nephrosis is intermittent, the tumor at one time being tense and at another soft and easily compressed, and if care be taken to measure the urine, the amount voided will be found to be increased with each subsidence of the tumor. The character of the urine is of no value in diagnosis when only one kidney is involved, for the healthy kidney is capable of keeping up the normal character of the excretion. The fluid in the affected kidney is a very dilute urine, having a specific gravity of about 1002, and containing the natural constituents in small amounts. When both kidneys are affected the condition is serious and may lead to uremic poisoning. The diagnosis in the case of a tumor forming in both loins can be settled by aspirating one or other kidney. The danger of hydronephrosis is destruction of the affected kidney, the constant pressure producing absorption of the excreting part of the renal substance, and eventually converting the whole organ into a fibrous sac containing fluid. When only one organ is affected, the opposite one often proves equal to the requirements of both, and the full amount of urine is excreted. The diagnosis must be made between hydronephrosis on the one hand and ovarian cyst, ascites, and hydatids on the other. On palpa- tion and percussion a dilated kidney has the colon in front of the swell- ing, and there is dulness in the lumbar region. -An ovarian cyst can be palpated by the vagina, and has its dulness in the middle line, gradually growing from the pelvis. In ascites the patient is like a rubber water- bag, the level of the fluid varying with change of position. Hydatids cause a painless, slowly-growing tumor, in rare instances having the hydatid fremitus, and definitely determined by the presence of vesicles in the urine. Treatment. — WHien there is evidence of obstruction of the ureter either by a calculus or other foreign body an attempt may be made to facilitate its passage toward the bladder by massage of the loin. The injection of water into the bladder to fully distend it has occasionally proved of assistance in favoring the release of a calculus down the ureter (Reghiald Harrison). Failing in these measures, the next effort should be to relieve the symptoms by aspirating the tumor. In some cases this has not only given immediate relief, but effected a permanent cure. If repeated aspirations prove unavailing, the next question to take into consideration is the opening and drainage of the kidney. The operation consists in a lumbar incision with an opening into the kidney, and the establishment of drainage until the sac consolidates or becomes a harmless sinus. This is preferable to nephrectomy, which has also been resorted to by some surgeons as a remedy for hydronephrosis. Pyonephrosis. — Just as water in the pleural cavity may be changed to pus, so a hydronephrosis may become a collection of purulent matter ; or if, during the course of a pyelitis, obstruction of the ureter takes THE GENITO-URINARY SYSTEM. 365 place, the secretion of pus gradually distends the kidney till it reaches the dimensions and character described under Hydronephrosis. The symptoms are practically the same. When a diminution in the size of the tumor takes place the excreted fluid is found to be pus. Tuberculosis of the Kidney. — Tuberculosis of the kidney is to be suspected when chronic renal symptoms exist, combined with a family history of tubercular disease. Males form a large majority of the patients, and the most susceptible period of life is during early adolescence and while the sexual functions are most active. One reason of this distinction is the important part which gonorrhea plays in the causation. The female when the subject of gonorrhea is more readily cured, and is not so liable to complications as the male, and when the tubercle bacillus attacks women it shows a decided preference for the lungs. In males a gonorrheal orchitis is almost a constant fore- runner of renal tuberculosis, and while it occasionally happens that the tubercular process begins in the kidney and makes its way downward, the opposite direction from testicle to kidney is the rule. Symptovis. — The patient is generally a male below middle age, having a family history of tuberculosis and frequently the subject of a chronic orchitis. With these data to start from, the symptoms of tuber- culosis in the kidney bear a close analogy to those manifested by the disease in the lung. There are hematuria, corresponding to hemopty- sis ; irritation in the urinary tract, causing frequent micturition, corre- sponding to cough ; and increase in the quantity and change in the character of the mucus, corresponding to expectoration in phthisis. Although hematuria can occur in the early stage of the disease, it is after ulceration has been established that it appears in its most marked form. Frequent micturition in children leads to a suspicion of stone in the bladder, and this source of error must be guarded against. As the disease advances the excess of mucus undergoes a change, and the urine is found to contain considerable quantities of pus. The thermometer is valuable here as in the diagnosis of pulmonary tuberculosis, a persistently high temperature in the latter part of the day being very characteristic. The demonstration of the bacilli in the urine settles the diagnosis beyond question. Treatmetit. — The general treatment as regards diet, climate, and hygiene are the same as indicated in pulmonary tuberculosis. The local treatment involves some serious considerations. When the tes- ticle is tuberculous, the gland should be treated as any other tuber- culous gland. If there be no evidence of the disease in any other part of the body, the cheesy masses should be removed or the testicle completely excised. The bladder requires close attention, especially when the urine is offensive. Injections of a weak solution of nitrate of silver, preceded and followed by irrigation, is one of the best methods of disinfection. Reginald Harrison recommends Iodoform suspended in mucilage in the proportion of five grains to the ounce. Nephrotomy or nephrectomy cannot be recommended, for the disease is seldom confined to one kidney or to any one portion of the urinary tract. Hydatid Cysts. — The kidney is much less frequently affected by hydatids than the lungs or the liver. In the majority of cases the left 366 SURGICAL DIAGNOSIS AND TREATMENT. kidney is the seat of the parasites, and males suffer more frequently than females. The cyst begins, as a rule, in the secreting substance, but occasionally in the cellular tissue beneath the capsule or surround- ing the pelvis. Small portions of the contents frequently escape through the ureter, and it is probably on this account that hydatid cysts of the kidney seldom attain to large size. Rupture is not uncommon, and the discharge may take place into the intestine or lung, but never externally through the loin. Sometimes the cyst undergoes inflammatory or absorptive changes, as happens in hydatids of other organs. Syviptonis. — When the tumor is small a hydatid cyst of the kidney may present no symptoms, and in the favorable cases in which it dis- charges through the ureter the disease may undergo a spontaneous cure without recognition. In many cases (52 out of 63, according to Roberts) vesicles are passed in the urine and afford the first clue to the nature of the affection. In their journey down the ureter these vesicles produce well-marked attacks of renal colic, and occasionally hydronephrosis. The tumor in the loin is smooth, but seldom is fluctuation elicited. When the vesicles get into the bladder they may produce irritation and tenesmus ; in the urethra they may cause retention of urine. In any case inflammation and suppuration may supervene, while blood and pus escape with the urine. The hydatid fremitus so constantly mentioned as a diagnostic sign is really of little value, owing to the extreme rarity with which it can be detected. To settle positively the diagnosis, exploratory puncture is a proper measure, the demonstration of the booklets under the micro- scope leaving no possible room for doubt. It must, however, be borne in mind that exploratory puncture is not devoid of danger. When it is necessary to resort to it the surgeon should be prepared to operate the moment the diagnosis is settled. Treatment. — The surgical treatment is the same as that indicated for hydatids of the liver. An incision as for nephrorrhaphy is made in the loin, the cyst freely opened, its edges stitched to the external wound, and the ca\'ity cleaned out and drained. Simple Cysts. — Serous cysts springing from the renal cortex are recognized on palpation as thin-walled globular tumors. Their con- tents vary from a thick jelly-like substance to a thin, straw-colored fluid containing albumin, cholesterin, and sometimes blood. There are few symptoms to aid the examiner except a painless, smooth tumor in the loin, growing slowly and producing neither dis- turbance of the general health nor derangement of the urinary organs. The diagnosis must rest upon the exclusion of other tumors of the kidney of a cystic nature. Solid Tumors. — Before five years of age and after thirty solid tumors of the kidney are not uncommon. No matter how fine the distinctions made by the pathologists, or how exhaustiv^e the classi- fication adopted by the clinician, tumors will always fall under one of two great classes — benign and malignant. In the kidney benign solid tumors are almost never found. When you make a diagnosis of solid tumor it is equivalent to saying that the growth is either a sarcoma or a carcinoma. For the sake of being systematic we adopt a classifica- THE GENITO-URINARY SYSTEM. 367 tion of renal tumors, and that of Paul seems to be the simplest and is sufficiently comprehensive : Of congenital origin : Sarcoma, hydronephrosis, cavernous tumors, dermoid tumors. Of adult origin : Cystic disease, cavernous tumors, sarcoma, adenoma, carcinoma. Syuiptoms of Solid Tumors. — In examining a tumor in the lumbar region the following points require attention : A kidney as it enlarges takes a direction forward, while an abscess or other lesion which can simulate an enlarged kidney causes bulging posteriorly. A kidney is always round, and can thus be distinguished from the liver, which has a sharp edge, and from the spleen, which has a characteristic notch. Fig. 156. — Carcinoma of the kidney from a patient aged eighty. Patient made a good recovery from the operation, but died two months later of persistent vomiting and dilated stomach (from a photograph in the collection of Dr. Andrews, Mankato). The kidney does not rise and fall with the respiratory movements as freely as does the liver. A tumor of the kidney has usually a resonant zone in front of it, which is the ascending or descending colon. This may be absent, owing to congenital malposition of the colon. When the intestine fails to give resonance on percussion, the bowel can some- times be felt as a cord-like structure between the tumor and the skin. Briefly stated, the distinctive symptoms of cancer of the kidney are a tumor in the lumbar region and hematuria (Fig. 156). The tumor grows in the direction of least resistance, which is forward, and over- lying it is the colon recognized by a zone of resonance. From tumors of the liver a renal growth is distinguished by the following points : 368 SCKGICAL DIAGXOSIS A .YD TREATMENT. 1. The liver rises and falls with respiration. 2. Hepatic tumors have no bowel-resonance in front. 3. The sharp edge of the liver can frc(]iu;ntl\' be felt; kidney tumors are always round. 4. Between a renal tumor and the edge of the ribs is a space into which the fingers can be pushed. Between a splenic and a renal tumor the differences are — 1. A splenic tumor has no bowel in front. 2. It has usually a well-defined edge, and sometimes a notch can be felt. Hematuria is found in about half the cases. It may occur at any stage of the disease, and is generally intermittent. When the amount of blood is large it may form clots in the ureter or bladder, and then renal colic or vesical tenesmus becomes a prominent symptom. In the intervals between attacks of hematuria the urine is normal or it may contain pus- or tube-casts. Pressure-symptoms are sometimes prominent. One or both legs may be edematous, and large veins may course over the abdominal wall ; the bladder may be irritable and the bowels constipated. Pain is not a constant symptom, but in a majority of cases it is pro- nounced. It is most prominent in the loin and abdomen, but is reflected down the thigh and around the back and shoulders. Treatment. — All congenital solid tumors of the kidney must be con- sidered malignant, and therefore the treatment is by no means hopeful. Internal remedies, such as iodid of potassium and Chian turpentine, have given some encouragement. When improvement appeared to take place it was only temporary. The toxins of er>'sipelas and bacillus prodigiosus enjoyed a reputation for a time, and several cases of sarcoma were reported as cured by their use. A most patient trial in three cases of my own ended in utter disappointment. The question of removal of the growth, including the kidney, is a most serious one. Of 35 operations reported by Mr. Sutton for renal sarcoma in children under six years of age, 15 recovered, but all died within a year from recurrence of the growth. If recognized at an early period of the disease, extirpation would give a chance of future im- munity, and several cases are recorded in which the patients remained free from recurrence at the end of two or three years. In adults, when urgent symptoms such as profuse hematuria or intense pain call loudly for relief, operation may afford the only prospect, but the possibility of cure is so remote that the brightest side that can be claimed for the operation is that it is likely to end the patient's suffering by an easy death. II. INJURIES AND DISEASES OF THE URETER. Surgical Anatomy. — The ureter is a muscular canal which carries the urine from the pelvis of the kidney to the bladder. Its average diameter is one-eighth to one-sixth of an inch, and its length from ten to thirteen inches. Its walls consist of three coats. The outer is composed of connective tissue with elastic fibers ; the middle coat is muscular, the fibers being; both longitudinal and circular; the inner THE GENITO-URINARY SYSTEM. 369 coat is composed of mucous membrane. The ureter lies behind the peritoneum, but bound to that membrane by fibrous bands, so that when the peritoneum is stripped from the parts behind the ureter always follows it. On this account the ureter is difficult to find in the bottom of a deep lumbar wound, especially in fat subjects. Its course is downward from the kidney, at first lying on the psoas muscle, and then crossing the bifurcation of the common iliac arteries. Although nearly straight, the tube really takes two curves — the first from the kidney to the brim of the pelvis, its convexity toward the middle line ; the second or pelvic curve has its convexity directed toward the outer wall of the pelvis. The ureters enter the neck of the bladder about two inches apart, running obliquely between the muscular and mucous coats for a distance of a half or three-quarters of an inch. In the male this opening is external to the vas deferens ; in the female the ureter penetrates the plexus of veins beneath the broad ligament. The canal is not absolutely uniform in caliber throughout its entire course ; Halle and Tanguery have shown that in normal subjects it is narrowed in three places — viz. {a) At a point between one and a half and two and a half inches from the pelvis of the kidney ; {d) at the junction of the pelvis and vesical portions ; and (r) at the place where it crosses the iliac artery. These are the localities where small stones from the kidney have been found to be arrested (Fenger). In palpating the ureter the following landmarks from Tourneur are of importance: At the junction of the internal with the middle third of Poupart's ligament erect a vertical line. This line corresponds with the course of the abdominal portion of the ureter. It crosses the brim of the pelvis four and a half centimeters from the middle line. This point is found by drawing a horizontal line from one anterior superior iliac spine to the other, and intersecting this by a vertical line through the pubic spine. At the point of intersection gentle steady pressure can be made by the fingers until the brim of the pelvis is reached. Tender- ness or dilatation of the ureter at this point can thus be detected. The vesical portion of the ureter can be palpated through the rectum in the male. When a stone is lodged in the ureter, even at a point high up, exquisite sensitiveness is experienced in this examination (Guyon, cited by Fenger). In females the ureter can be palpated through the vagina for a distance of two or three inches as it runs in the broad ligament close to the upper wall of the vagina (Cabot). Rupture of the Ureter. — It would seem almost impossible that the ureter should suffer injury, protected as it is by strong masses of muscle and fat and guarded by promontories of bone. When rupture does occur, it is by the application of very great violence to the trunk or abdominal region. The kick of a horse, the passage over the body of a heavily-laden wagon, a blow from the handle of a wheelbarrow, violent over-stretching, and other traumatisms have been reported as causes. Symptoms. — The symptoms are generally obscure, and often they are long delayed. When the bladder or the kidney is ruptured, the symptoms are prompt in making their appearance. Not so with the ureter, for at the beginning there are no grave symptoms unless some other important organs are injured. 24 370 SURGICAL DIAGNOSIS AND TREATMENT. When there is an external wound through which urine is found to escape the diagnosis is positive. In the absence of this sign the evi- dence must rest hirgely on the nature and severity of the injury. In some cases the urine is bloodstained. A swelling in the loins and a collection of fluid, which when drawn off by the aspirator is found to resemble urine, are very suggestive of rupture. This swelling does not occur until some time after the receipt of the injury. The time varies from seven days to seven wrecks. The swelling is round, oblong, or sausage-shaped, following the course of the canal, and is paljiable from the abdomen (Fcnger). The fluid which produces the swelling just mentioned is not pure urine, nor is the rupture of a ureter followed by extravasation of urine, as we would naturally infer. The clinical fact remains that in cases of ruptured ureter a fluid is poured out at the seat of rupture which is not productive of the disastrous consequences which follow extravasation of urine in other parts. When extravasation of urine takes place in the scrotum or perineum from ruptured urethra, inflammatory symp- toms soon appear and rapidly proceed to gangrene of the parts involved. In rupture of the ureter a swelling forms and continues for days or weeks without any inflammation or gangrene. In explanation of this singular condition Reginald Harrison suggests that the rupture of the ureter is followed by the formation of clots, not only in the ureter, but in the corresponding kidney ; that these ante-mortem clots are a provision for the substitution of a kind of urine which is incapable of proving destructive to the tissues with which it may come in con- tact. In a case of his own he was able to examine this kind of urine, and found that there w^as almost a complete absence of 'urea. There being no urea to decompose, there is no source for the production of the ammonia by which the destruction of tissues is eflected when nor- mal urine is extravasated. The absence of urea renders the urine chemically harmless to the tissues with which it comes in contact. One of the consequences of ruptured ureter is the formation of dense and unyielding strictures. As a consequence of stricture the kidney may suffer from hydronephrosis and undergo atrophy. Treatment. — If an early diagnosis can be made (and this is only possible when there is a wound through which urine is trickling), the proper treatment of ruptured ureter would be to enlarge the incision, find the divided ends of the tube, and unite them in the manner which will be presently described. So far, this has not been attempted. In the majority of cases the diagnosis is arrived at after the formation of a swelling due to a collection of modified urine above described. The treatment in vogue for this condition is puncture or incision, and drain- age either through the abdominal cavity or by a lumbar incision. Nephrectomy has been resorted to in a number of these cases and in accidental division of the ureter during celiotomies. Nephrectomy is too radical an operation to be thought of before every other expedient has been tried to restore the function of a rup- tured or severed ureter. Instead of proceeding deliberately to remove the kidney, an exploratory incision would be the proper course. Search should be made for the ends of the ureter, and if found an attempt should be made to unite them. Access to the ureter can be had by THE GENITO-URTNARY SYSTEM. 37 1 the abdominal or by the lumbar incision. An incision in the middle line or a little to one side exposes the whole length of the ureter with little difficulty, but the operation is intra-peritoneal, and unless the urine is aseptic the danger of peritonitis is great. The lumbar incision ren- ders it more difficult to reach the ureter, owing to the depth of the wound, but when it is practicable it should be chosen as much the safer operation. The incision begins at the lower border of the twelfth rib, at the edge of the erector spinae muscle, and extends along a line one inch anterior to the ilium, and thence along Ponpart's ligament to about its middle. Only the upper two-thirds of the ureter can be ex- posed by this procedure. Van Hook's method of suturing the divided ureter (uretero-ureter- ostomy) is as follows: i. " Ligate the lower portion of the tube one- eighth or one-fourth of an inch from the free end. Silk or catgut may be used. Make with fine sharp-pointed scissors a longitudinal incision twice as long as the diameter of the ureter in the wall of the lower end one-fourth of an inch below the ligature. 2. " Make an incision with the scissors in the upper portion of the ureter, beginning at the open end of the duct and carrying it up one- fourth of an inch. This incision ensures the patency of the tube. 3. " Pass two very small cambric sewing-needles, armed with one thread of sterilized catgut, through the wall of the upper end of the ureter one-eighth of an inch from the extremity, from within outward, the needles being from one-sixteenth to one-eighth of an inch apart and equidistant from the end of the duct. It will be seen that the loop of catgut between the needles firmly grasps the upper end of the ureter. 4. " These needles are now carried through the slit in the side of the lower end of the ureter into and down the tube for half an inch, where they are passed through the wall of the duct side by side. 5. "It will now be seen that the traction upon the catgut loop passing through the wall of the ureter will draw the upper fragment of the duct into the lower portion. This being done, the ends of the loop are tied together securely, and, as the catgut will be absorbed in a few days, calculi do not form to obstruct the passage of the urine. 6. " The ureter is now enveloped carefully with peritoneum, as already described in other operations, provided an intra-peritoneal operation has been done." As an additional security against leakage Bloodgood recommends the application of two sutures through the external coats (Figs. 1 57-161). Another method of dealing with a divided ureter is b)' ituplantatioii. When there is loss of substance or when from any cause the ends of the tube cannot be approximated, the following expedients have been resorted to : 1. Implantation of the proximal end of the ureter into a loop of intestine. This is objectionable on account of the risk of septic infection of the kidney by the gases escaping from the bowel. 2. Implantation into the bladder. When the proximal end of the ureter is long enough to reach the bladder, this procedure is better than any other, as it re-establishes the natural course of the urine and is free from danger of septic infection. 372 SURGICAL DIAGNOSIS AND TREATMENT. Fl>.. 1-,/. — L itifio-urfterectomy (Van Hook's method). The needles have been introduced into the wall of the renal portion of the ureter. The end of the vesical portion of the tube has been ligated and a slit made in its wall.

When the ureter is divided in THE GENITO-URINARY SYSTEM. 373 the pelvis and cannot be connected with the bladder and vagina, it has been suggested by Van Hook to attach the proximal end by sutures to an opening in the skin. Ureteral Calculus. — A stone in the ureter is likely to be arrested at one or other of three portions of the tubes which are naturally nar- rowed — that is to say, at a point between one and a half and two and a half inches from the pelvis of the kidney, at the junction of the pelvic and vesical portions, and at the point where the ureter crosses the iliac artery. Of these three portions, the upper is most frequently the lodging-place of a calculus, while stone is found in about equal frequency in the two lower portions. Diagnosis. — The diagnosis of stone in the ureter is only possible in that portion of the duct which can be palpated from the rectum or vagina. Even when thus favorably located errors in diagnosis are apt to occur. A calculus palpated from the vagina is likely to be mistaken for a diseased ovary, as happened in Collingworth's case. The symp- toms of stone in the upper portion of the ureter are those of stone in the kidney, and a differential diagnosis is impossible. Removal of stones from the ureter is effected by different methods according to their location : 1. Longitudinal Ureterotomy. — When the calculus is lodged in the upper part of the ureter an attempt should be made to push it back into the renal pelvis, whence it can be withdrawn through an incision in the renal tissue. Failing in this, an incision should be made in the long axis of the ureter over the stone. The wound in the ureter is care- fully closed with sutures if the operation is intra-peritoneal. When extra-peritoneal no sutures are required, as the urine can be drained until the wound closes by granulation. The consequences of obstruction with calculi of one or both ureters are serious. When one tube only is obstructed, absorption and dis- integration of the corresponding kidney take place. When both tubes are occluded, speedy death results from mechanical suppression of urine. 2. Ureterotomy through the Vagina. — When by palpation a stone can be felt in the lower end of the ureter, its removal by way of the vagina may be accomplished without great difficulty. The usual posi- tion of the calculus is in the broad ligament close to the cervix uteri. The incision is best made with scissors, and the wound can be closed with interrupted sutures. 3. Removal through the Rectum. 4. Removal through the Bladder. — The stone may be so near the lower end of the ureter as to give a click when examined with a sound. In this case the urethra is dilated, and also the orifice of the ureter if necessary, and the stone withdrawn. Whitehead removed eleven calculi in this manner. Sometimes the mucous membrane has to be divided before the stone can be set free. Ureteritis. — Inflammation of the ureter is probably a quite com- mon condition, but masked by renal and vesical diseases. According to Mann, ureteritis has seven causes: (i) injuries during childbirth; (2) previous disease of the bladder ; (3) gonorrhea ; (4) suppuration of the pelvis of the kidney ; (5) pelvic inflammations and tumors ; (6) 0/4 SURGICAL DIAGNOSIS AND TREATMENT. abnormal conditions of the urine; (7) tuberculosis. The pathological changes produced by inflammation are in some cases a slight swelling of the tubes and desquamation of the epithelial lining ; in others a purulent condition indicating ulceration of the lining membrane ; in still another class the tube is thickened, increasing the caliber of the ureter to the size of a lead-pencil or larger. Symptoms. — The most constant symptoms are frequent or almost continuous micturition and a boring pain along the course of one or both ureters. The left suffers more frequently than the right. The disease is usually chronic in its course, and great depression of spirits is not uncommon. Treatment. — The general treatment consists in securing the best hygienic surroundings, avoiding alcoholic and other irritating bever- ages, and paying careful attention to diet. The bowels should be kept relaxed and alkalies should be given continuously. For improving the condition of the urine copaiba, oil of sandalwood, and benzoic acid are recommended. Local applications of nitrate of silver or boracic acid may be made to the ureters after first dilating the urethra in the manner recommended by Simon, Pawlik, and Kelly.

There is a question whether stricture can THE GENITO-URINARY SYSTEM. • IJ^ be caused by gonorrheal infection spreading from the urethra to the bladder and thence to the ureter. Tumors in the pelvis and abdomen are common causes of obstruction of the ureters. In many of the cases stricture results from the healing of ulceration caused by the temporary obstruction of a calculus or by the healing of a tubercular abrasion. Operations for the Relief of Stricture of the Ureter. — i. Fenger's method consists in making a longitudinal incision at the seat of stric- ture and converting it by sutures into a transverse incision. The ureter is opened above or below the stricture and the incision carried through the constricted portion, as seen in Fig. 162. The upper and lower ends of the longitudinal wound are then brought together by folding the ureter upon itself The remainder of the wound is approximated by sutures which catch the outer and middle coats, thus converting the longitudinal into a transverse wound (Fig. 162). 2. Dilatation by bougies has been successfully practised by Alsbe'rg in a case of stricture near the pelvis of the kidney attended by hydro- nephrosis. 3. Resection of the ureter and implantation of the distal end into the pelvis of the kidney. III. INJURIES AND DISEASES OF THE BLADDER. In the general examination of a patient our attention is usually drawn to the bladder by one or more of the following symptoms — viz, pain, frequent micturition, and hematuria. The significance of these symptoms we shall now consider. Pain. — This is not necessarily felt at the seat of the disease, but, like the pain in hip-disease, may be felt at a distance. Stone in the bladder produces pain on the under surface of the penis a little behind the meatus. When the kidney is the seat of the disease, pain is felt in the groin, in the testicle, and down the thigh. Disease in the testicle pro- duces pain along the inguinal line. These are reflected pains, and are felt at the termination of the nerve and not at the spot where the nerve is irritated. Direct pain, however, is not uncommon. When the bladder becomes over-distended the pain is felt over the viscus itself Urethritis causes pain at the seat of the inflammation, which is always accentuated by external pressure at that point. In inflammation of the prostate the pain is most marked in the perineum and rectum, and is greatly in- creased by digital pressure by way of the rectum. Combined with these direct we may also have indirect pains running along the course of the urethra, and leading us to suspect the presence of stone in the bladder. A valuable aid to diagnosis is a consideration of the time at which pain is felt. If it is felt during micturition, we naturally suspect inflam- mation in the urethra, the prostate, or the bladder. A patient with stone in the bladder complains of pain at the end of micturition, and well he may, for the viscus, after expelling all the urine, violently con- tracts upon the calculus in a vain but painful effort to get rid of the foreign body. Pain that is felt before the act of micturition, and which 376 SURGICAL DIAGNOSIS AND TREATMENT. ceases after tlie act, is due to cystitis or to retention of urine. Pain durinL^ micturition, <^reatly aggravated by the act of defecation, is an indication of inflammation in the prostate. Frcijucnt Micturition. — The expulsion of urine from the bladder is a reflex act. In the normal condition the urine trickling down the ureters gradually expands the bladder till a certain degree of irritation is applied to the terminal branches of the sensitive nerves which supply the viscus. This stimulus runs up the sensory nerves to the spinal cord, and thence to the motor nerves which supply the muscles of the bladder and ure- thra. These muscles contract and empty the bladder. Any stimulus applied to the terminal branches of the sensitive nerves will produce the same result ; consequently, frequency of micturition is a symptom of cystitis, urethritis, or prostatitis. It also occurs when the capacity of the bladder is lessened, when the urine undergoes certain changes, when there is phimosis, contracted meatus, stricture, or calculus. Taken by itself, frequent micturition is a symptom of very indefinite signif- icance. When it is met with, the question should be decided as to whether it is increased by exercise or by rest. A stone or a tumor in the bladder may be suspected when movement increases the frequency ; atony of the bladder and disease of the prostate are to be suspected wl^en the frequency of urination is increased by rest. The size and force of the stream should be carefully noted. A small stream is caused by stricture, by a contracted meatus, or by inflammatory swelling in some part of the urethra. If the time spent in the act of micturition is lengthened and the force of the current is slow, obstruc- tion may be suspected, the most common causes of which are stricture, prostatic disease, and muscular atony. Hematuria. — Bleeding may occur from any part of the urinary tract, and by close observation we can generally locate its origin. When it comes from the kidneys it is well mixed with the urine, giving the fluid a smoky appearance. In addition there is a history of renal disease, as indicated by albuminuria, the presence of granular or hyaline casts, degeneration of the retina, etc. The color alone should not be relied upon, for smoky or beef-tea-colored urine may be produced when blood in small quantities escapes from the bladder-wall and has time to mix freely with the urine before being expelled. Black or coffee- colored blood is produced by profuse hemorrhage from the bladder accompanied with retention from clotting. Blood from the ureter is an accompaniment of renal colic, and is usually due to the passage of a calculus on its way from the kidney to the bladder. The quantity of blood is seldom large, but the terrible pain up the back and loin, in the testicle, and down the thigh leaves little doubt as to its origin. Hemor- rhage from the prostate comes away in clots, and is usually a concom- itant of chronic disease of the gland, such as tuberculosis or carcinoma. The prostate is generally enlarged. When the urethra is the seat of hemorrhage it is generally due to the use of instruments. The blood comes before the urine and is clotted. The bladder is frequently the seat of hemorrhage, owing to the presence of calculi and morbid growths, especially papillomata. We recognize this source of bleed- ing by excluding the other localities and by the history of the case. As a rule, the blood comes with severe straining at the end of urina- THE GENITO-URINARY SYSTEM. ^yj tion. An ingenious test for ascertaining the existence of a wound or abrasion of the bladder is the so-called absorption test of Ultzmann. A solution of iodid of potassium is injected into the bladder. If there is a breach in the continuity of the mucous membrane, the iodid is absorbed and can be detected in the saliva. The absence of iodin in the saliva would indicate an uninjured mucous membrane. The follow- ing axioms from E. Hurry Fenwick may be taken as in the main correct : 1. " The brighter and more arterial the color of the urine, the nearer the source of the bleeding is to the meatus urinarius. 2. " Long dark clots like earth-worms or quill-barrels indicate bleed- ing from the renal pelvis, for they are clots or moulds of the ureter. 3. " Large irregular-edged scarlet clots are derived from a bladder source if traumatism of the kidney and renal tumor are excluded. 4. " Blood appearing toward or at the finish of clear urination denotes a vesical or a prostatic origin. 5. " Blood issuing from the meatus independently of micturition is from an urethral source." In cases of doubt the microscope may throw some light upon the source of the hemorrhage. Blood-casts indicate the renal tissue as the seat of hemorrhage, and the same is true of granular casts. When the bladder is the seat of a morbid growth small portions of the neo- plasm are likely to be voided with the urine, and may be subjected to the microscope. The voided blood may be further examined by allowing it to subside in a conical glass. Of this test Von Jaksch says : '* When blood-cells are intimately mixed with the urine in such a way that, though present in large quantity and deeply tingeing the fluid, they do not form a sedi- ment after many hours' standing, it may be inferred that the hemor- rhage took place in the substance of the kidney or in the renal pelvas or ureters. If, under these circumstances, they are seen with the micro- scope to be profoundly altered, having lost their coloring matter and presenting the appearance of pale yellow rings, the further conclusion results that the blood has been effused from the kidney itself, and the symptoms point to acute nephritis or to a fresh exacerbation in the course of chronic nephritis." Having completed the examination of the urine, the next step in the investigation of the seat of hematuria is a physical examination of the various parts of the urinary tract as follows : I. The Kidneys. — The method of palpating the kidney has been already described. By palpation we ascertain the presence or absence of tenderness of the kidney. Tenderness can be elicited on deep pressure in the following conditions : viz. pyelitis, chronic abscess, inflamed cyst, and acute suppurative nephritis. A stabbing pain elicited by pressure over the front of the kidney is very suggestive of renal calculus, but too great stress should not be laid upon the absence of this sign. Enlargement of the kidney may be due to the following conditions : {a) It may be a simple hypertrophy of the organ to com- pensate for atrophy of its fellow, [b) It may be due to the presence of a large calculus and to the inflammatory changes which such foreign bodies produce, (e) Tuberculosis is a common cause of enlargement: 378 SCRG/C.IL DIAG.VOSIS AND TREATMENT. this condition appears after the age of twenty and the patients show a history of tuberciihir disease in other organs. (<■/) Hydronephrosis is suggestive of obstruction by calcuH or the twisting of the renal vessels and ureter, [c) Perinephritis with abscess in its early stages produces adhesions and subsequent contraction which draw the kidney upward beneath the ribs. (/") Tumors of the kidney, which in the vast majority of cases prove to be sarcomata or carcinomata. 3. The Ureters. — Deep pressure along the course of the ureters may elicit tenderness in the whole course of the tubes, and is suggestive of ureteritis. If the tenderness is only found in spots, calculi are probably the cause. The examination of the lower portions of the ureters per rectum in males and per vaginam in females must not be neglected. 3. Tlic Bladder. — By rectal or vaginal examination the base of the bladder can be felt and any thickening or induration readily determined. After the age of forty-five the most common cause of thickening is carcinoma, and, as the infiltration begins near the opening of one or other ureter, the thickening occurs to the right or left of the middle line. Care should be taken in this examination, for rough palpation is frequently followed by profuse hemorrhage. Hardness and thickening are also felt when the bladder contains a calculus, and particularly if the stone is sacculated. Injuries of the Bladder. Rupture. — The bladder is liable to rupture by direct violence applied to the lower portion of the abdomen, and it may be laid down as an axiom that the more the bladder is distended the greater is the risk of this injury. Bullets and other missiles are causes of rupture which attack the bladder from without. The viscus may be ruptured from within, and the most frequent cause is the laceration of its wall by a fragment of bone occurring in severe fractures of the pelvis. Injuries to the rectum or vagina not infrequently involve the bladder. The bladder has sometimes ruptured by over-distention, as when filled preparatory to the operation of cystotomy. It is only when its walls are weakened or sacculated from previous disease that this is likely to occur. In any severe injury of the pelvis or hypogastrium, if the patient be unconscious or has not the power to micturate, a catheter should be passed into the bladder and the effect carefully noted. Rupture of the bladder is of two kinds — intra-peritoneal and extra- peritoneal. When the organ is ruptured and its contents escape into the peritoneal cavity, the most serious consequences follow : the shock is profound, and unless prompt treatment is resorted to the patient dies in from three to seven days. In such a case the catheter will be found to draw off only a small quantity of blood-stained urine. If the instru- ment happens to enter the laceration, it will pass freely up beyond the natural limit of the bladder. The catheter, however, may impinge against an unbroken portion of the bladder, in which event the con- traction of the viscus prevents the instrument from passing its normal distance, and it appears to have gone in a wrong direction. To settle the point pass a finger into the rectum, when it will be found that the catheter is in the proper position, but firmly grasped by the bladder. THE GENITO - URINA RY SYS TEM. 379 Should the surgeon still be in doubt as to the existence of intra- peritoneal rupture, he may next proceed to measure the capacity of the bladder. A rubber catheter is inserted, and Peterson's rubber bag passed into the rectum and distended with warm water. The bladder is then slowly filled by allowing a measured quantity of some mild anti- septic solution to flow through the catheter. If free from rupture, it can be felt to rise out of the pelvis and its limits can be defined by per- cussion. After the injection of six or eight ounces the fluid is allowed to flow out by the catheter, after which it is carefully measured and compared with the quantity injected. If the amount withdrawn is equal to the amount injected, the bladder is not ruptured. Another means of diagnosis is the injection into the bladder of filtered air through a Davidson's syringe over the outer end of which cotton has been tied. If there be an intra-peritoneal rupture, the air will inflate the whole abdomen ; if the bladder be intact, it alone will be distended. Should this injection produce emphysema of the cellular tissue, it proves that an extra-peritoneal rupture of the bladder has taken place. Treatment. — Several cases are on record in which careful drainasfe by a catheter, retained just inside the neck of the bladder, has been followed by recovery. This method, however, is not to be relied upon. As soon as possible after a satisfactory diagnosis has been made the abdominal cavity should be opened by an incision in the middle line just above the pubes. The rent in the bladder having been found, it is closed by a double row of carbolized silk sutures. There has been considerable discussion ov^er the question of retaining a catheter in the bladder after this operation. The weight of opinion seems to be in favor of dispensing with the catheter. If the rent in the bladder be closely secured so as to prevent leakage, a moderate degree of disten- tion is less likely to do harm than the retention of the catheter in the bladder for several days. In extra-peritoneal rupture of the bladder the urine is extravasated in the prevesical connective tissue or into the vesico-rectal or vesico- uterine space. Its diagnosis is arrived at by exclusion of the intra- peritoneal variety, by the production of cellular emphysema when the bladder is distended with filtered air, and by the presence of urinary infiltration. When there is an injury which from its position evidently implicates the parts concerned in micturition, and when, after examina- tion of the rectum or vagina, and the use of the catheter as already described, there is still doubt, a perineal incision should be made into the membranous portion of the urethra for the purpose of digital ex- ploration of the neck of the bladder. On this point Reginald Harrison observes : " Many patients in cases of this kind have undoubtedly been lost for the want of that knowledge which can only be thus obtained. Where the suspicion is grave the possibility of not finding such a lesion by exploring should not be allowed to weigh against making the at- tempt. If a pelvic fracture with rupture of the viscus or rupture alone is discovered, a drainage-tube should be inserted into the bladder. If the prevesical space is also opened, an additional aperture above the pubes will be required in order that thorough drainage may be pro- vided. Procedures of this kind are safe and slight compared with the risk connected with extravasation of urine imperceptibly going on in 380 SURGICAL DIAGNOSIS AND TREATMENT. a part where otherwise drainage is impossible and subsequent absorp- tion uncertain." The danger of this form of rupture is in the pent-up extravasated urine, which if allowed to remain in the tissues speedily produces cellu- litis and sloughing, ending in many cases in septicemia. The treatment, therefore, must consist in free incision to allow the extravasated urine to escape, and, w^hen necessary, in free drainage by the perineal or suprapubic route, or both. Incised wounds in the hyj^ogastric region are liable to be compli- cated with wound of the bladder ; the methods of diagnosis are the same as for rupture. When a wound of the bladder is suspected, the urine should be drained off through the external wound or by a cath- eter in the urethra. Wounds of the anterior bladder-wall heal readily by granulation, and in view of the slight trouble which such wounds give when intentionally made in the operation of cystotomy, they should be dealt with on the principles which govern that operation. Retention of Urine. — In its expulsion from the bladder the urine has to pass through a long tube having a small caliber and tortuous course — the urethra. Retention or inability to expel the urine is due to two classes of causes — viz. those which produce obstruction in the urethra, and those which result in a want of expulsive power. Of obstructive causes, by far the most common is stricture of the urethra, which may be organic or spasmodic. Other causes are enlarged pros- tate, inflammation or abscess of the prostate, impacted calculus, tumors of the bladder or urethra, pressure of the gravid uterus, and atresia of the urethra or meatus urinarius. The expulsive power may be wanting from any of the following causes : paralysis, atony of the bladder, reflex influences such as occur after the ligature of hemorrhoids. Retention is common in shock and in the great muscular exhaustion which attends fevers. Certain drugs, as opium, belladonna, cantharides, and alcohol, by their toxic influence produce want of expulsive power. Diagnosis. — The symptoms of retention are very plain. Besides the inability to micturate, the patient complains of pain in the region of the bladder and the kidneys. There is a constant desire to empty the bladder, and the patient makes violent straining efforts, which some- times expel the contents of the lower bowel. In many cases a few drops come aw^ay and lead to the erroneous belief that the bladder is being emptied. After a time the symptoms of uremic poisoning super- vene — viz. rigors, fever, failing circulation, and death. In less acute cases the backward pressure of the urine produces destructive changes in the kidneys. On palpation the round distended bladder can be felt in the hypogastrium, sometimes extending to or even beyond the umbilicus. On percussion this tumor is dull, while the flanks on either side are resonant. In thin persons the tumor can be distinctly seen through the parietes, and is more prominent when the patient is in the erect position. Treatment. — This must depend upon the cause of the retention. In the majority of cases the catheter is indicated, and should be resorted to wathout delay. In some cases it is impossible to pass a catheter, and aspiration of the bladder then becoms imperative. This can be done by three different routes : THE GENITO-URINARY SYSTEM. 38 1 1. Suprapubic. — The operation is very simple and free from danger. The pubis having been shaved and thoroughly disinfected, the aspi- rating needle is inserted in the middle line just above the symphysis pubis, and the bladder emptied. The puncture is then sealed with iodoformized collodion. This route should be chosen in preference to either of the two following. 2. Rectal. — Tapping the bladder by way of the rectum was formerly much in vogue. A large curved trocar was passed into the rectum and made to pierce the bladder just behind the base of the prostate. 3. Perineal. — This route is recommended when there is enlargement of the prostate, but in every other condition it is inferior to the supra- pubic route. Atony of the Bladder. — Atony of the bladder is a condition which is almost analogous to dilatation of the stomach. Its most important feature is that the viscus cannot e.xpel the whole of its con- tents. At the end of micturition there is still a quantity of urine left in the bladder, to which the name " residual urine " is applied. The causes of atony are numerous. Every male who has passed the period of middle life has less expulsive power than he had in youth, and this debility increases as age advances. This, however, cannot be regarded as a morbid condition. The term " atony " is more correctly applied to a paresis of the muscular coats of the bladder. Coincident with this are certain changes in the vesical walls. They may undergo fatty degeneration and become atrophied, thinned, and distended. An almost opposite condition is sometimes observed, wherein the walls are changed by the formation of fibroid tissue, leading to contraction of the viscus and reduction of its capacity. Among the causes of atony may be mentioned stricture of the urethra, enlargement of the prostate, tumors in the vicinity of the neck of the bladder, and neglect to empty the bladder at proper intervals. All of these causes act in one direction — they produce ov^er-distention. A single failure to relieve the bladder at the proper time is sufficient to produce atony. Symptoms. — Atony of the bladder is to be taken into consideration when there is any cause of over-distention, as stricture, enlarged pros- tate, etc. After the patient has micturated and emptied the bladder to the extent of his ability, a catheter should immediately be passed. If it be found that an ounce, two ounces, even a larger quantity, of residual urine flows through the catheter, the case is one of either atony or sacculation of the bladder. It may be impossible to make a differential diagnosis between the two. In sacculation a soft catheter may empty the general cavity of the bladder, and after all the urine has ceased to flow a change in the position of the instrument may be followed by the flow of a quantity of residual urine. In atony the residual urine comes away with any form of catheter. Treatment. — The most serious feature of atony is the retention of the residual urine and the chain of evils which are apt to follow — viz. decomposition of urine, cystitis, retention, and degenerative changes in the kidney. To guard against these the regular and persistent use of the catheter is necessary, and the patient should be taught to use the instrument for himself The frequency of its employment must depend upon the amount of residual urine. When after the act of micturition 382 SURGICAL DIAGNOSIS AND TREATMENT. the bladder still retains four ounces, the catheter should be used night and morning ; when six ounces are retained, the instrument is indicated three times a day ; and if there be eight ounce of residual urine, it will need to be withdrawn every six hours. Use the catheter once a day for cverv tzc'o ounces of residual urine. The patient should be taught not only the use of the catheter, but the manner of disinfecting it and keeping it surgically clean. The medicines of any value in giving more healthy tone to the walls of the bladder are strychnin, iron, tincture of cantharides, and ergot, but too much must not be expected from their employment. Electricity is of great value in mild recent cases, and is a help to other measures when the condition is long continued and severe. It is employed as follows : an insulated electrode is passed into the bladder, while the other electrode is applied to the hypogastric region or passed into the rectum. A mild current is employed, and gradually increased till the patient complains of discomfort. When cystitis complicates atony, special treatment must be directed to the inflammator)' condition. Sacculation and Pouching of the Bladder. — Two other con- ditions closely allied to atony are sacculation and pouching of the bladder. These terms are frequently used as synonymous. Sacculation may be defined as a hernia of the vesical mucous membrane through a weakened part of the muscular coat of the bladder ; hence this portion of the bladder has no power to empty itself and becomes a receptacle for residual urine and for calculi. It is usually the result of over- distention, and may occur at any age and at any portion of the organ. Of the causes which lead to sacculation obstruction to the flow of urine plays the most important part. Intra-uterine pressure is also a not infrequent cause, while a third class of cases are of traumatic origin. The diagnosis of sacculation is not always easy. A soft or flexible catheter passed into the bladder is found to draw off a certain quantity of urine ; the position of the instrument is changed and the flow^ recommences. This is ver)^ suggestive of sacculation, and if the cha- racter of the urine drawn off from the two compartments is found to be materially different, the evidence is conclusive. Guthrie demonstrated the presence of sacculation by injecting the bladder with twelve ounces of warm water, and finding that only ten ounces could be withdrawn. Sometimes when digital examination is made by rectum or vagina the sacculation can be felt as a tumor in the proximity to bladder. Should the examiner meet with a tumor of this character, an effort should be made to pass a catheter into it ; if he succeed, the tumor will quickly disappear. One of the most serious results of sacculation is that it affords a hiding-place for calculi. Stones thus imbedded cannot be dealt with by the lithotrite, and even if they could the detritus would be sure to collect in the pouch and renew the trouble. The best way to deal with a stone thus sacculated is to make a suprapubic cystotomy, remove the stone, and treat the sacculation by drainage (Reginald Harrison). Pouching differs from sacculation in that the whole thickness of the bladder is involved. It is also confined to the most dependent part of the bladder, and is in nearly all cases met with in persons well advanced THE GENITO-URINARY SYSTEM. 383 in years. A good-sized stone has a tendency to cause the floor of the bladder to form a pouch, and when this occurs the removal of the calculus can only be accomplished by a cutting operation. Treatment. — Drainage of the bladder is the best method of dealing with sacculation or pouching. The effect of a sea-voyage is often remarkable ; on this point Mr. Harrison observes : "I have known thick, cystitic urine, due to the pollution of the general cavity of the bladder by the contents of a stagnant sac, entirely recover itself when placed under these conditions. The constant movement of the ship both by day and night and in whatever position the body may occupy renders stasis of any of the fluids of the body impossible, and thus one element necessary for decomposition is removed. The immunity of seamen from stone and certain bladder affections may in some measure be due to this. In one instance at present under my observation, where there is very little doubt the patient has a sacculated bladder, the urine is invariably clear and normal when he is at sea, and turbid and offen- sive when he is on shore for any length of time. Yet in other respects, as far as I can judge, the conditions are the same." Cystitis, or Inflammation of the Bladder. — It is customary to divide cystitis into two varieties, acute and chronic. The symptoms are almost identical in both, and, as every degree of chronicity is met with, it is sometimes difficult to draw a dividing-line. Acute cystitis may arise from a great variety of causes — for exam- ple, direct injury to the bladder-walls by the unskilful use of sounds or other instruments ; the presence of foreign bodies, either pushed into the bladder by way of the urethra or arising from within in the shape of calculi or fragments thereof; the use of cantharides ; the extension of inflammation from the urethra, as in stricture or simple urethritis ; the infection of micro-organisms, as the gonococcus or tubercle bacillus, and the presence of new growths, as carcinoma. One of the chief dangers of cystitis is the liability of the inflamma- tion to spread by way of the ureters to the kidney, causing a pyelitis, a pyelo-nephritis, disorganization of the kidney, and frequently death. The changes which take place in the bladder-walls are congestion, thickening of the mucous membrane, desquamation of the epithelial lining, and the formation of raw surfaces. In advanced stages of the disease the tissues become infiltrated with pus, and ulceration and sloughing are not uncommon. In some instances the inflammation is attended with the formation of a false membrane, which may be voided in pieces or in casts of considerable portions of the bladder. This may be a true diphtheritic membrane, the disease attacking the bladder simultaneously with other regions of the body. Symptoms. — The first symptom to usher in an attack of acute cystitis is generally frequent viicturition. This increases ; the patient is obliged to empty his bladder more and more frequently, till at last he is kept constantly getting in and out of bed. Vesical tenesmus is also a prominent feature ; the sufferer strains, trembles, and perspires, but can only expel a few drops of urine at a time. A feeling of weight in the perineum is not uncommon, attended with a sensation as if some foreign body were there which ought to be expelled. A few hours after the onset of the symptoms just mentioned pain 384 SURGICAL DIAGNOSIS AND TREATMENT. becomes a prominent feature. It is usually deep-seated, and felt above the pubes, down the ^roin and thighs, and at the end of the urethra. Pressure over the bladder elicits tenderness. CJiangcs in the urine can be observed at an early period of the dis- ease. It is high colored, and at the end of each effort to empty the bladder a few drops of blood are expelled. More or less mucus gives the urine a thickened appearance ; lithatcs appear in abundance, and later the fluid becomes ammoniacal. The coiistitutio)ial symptoms do not follow a definite course. Rigors or chills are sometimes met with, and a high temperature and rapid pulse may exist throughout the attack. Treatment. — Whatever the form in which cystitis presents itself, the first indication is to ascertain and remove the cause. Fragments of stone, retained unhealthy urine, gonorrheal secretions, or any other excitants should be sought for and either removed or their influence counteracted. The pain will call most loudly for prompt action. Injec- tions of warm water into the rectum often afford great relief, but, as a rule, opiates will be required. Half a grain of morphin dissolved in half a pint of water and at a temperature of about 110° F., injected into the rectum, will be followed by an exquisite sense of relief, putting a speedy stop to pain, tenesmus, and constant micturition. Supposi- tories will produce the same effect, but their action is not so prompt. The patient should keep his bed, be restricted to a light diet, and par- take freely of diluent drinks. Hot fomentations and hip-baths are favorite remedies, and the internal administration of hyoscyamus has long enjoyed the reputation of being the most useful single remedy in inflammatory affections of the bladder. Chronic cystitis is frequently a continuation of the acute form. It is often a result of enlarged prostate, of calculus, atony, stricture, and new growths. Its origin is often traceable to the kidney, to defective digestion, or to gout. The symptoms in general are those of the acute form, but not so pronounced. There may be little pain ; tenesmus may be slight or absent. Micturition is usually less frequent, and the majority of patients are able to move about, but they suffer incon- venience which makes their lives more or less of a burden. The urine seldom contains blood, but to offset this it is thick, filled with ropy mucus or pus, and often ammoniacal and foul-smelling. Catarrh of the bladder is a popular name for this disease. Treatment. — Removal of the cause must claim the closest attention. Many a patient who has suffered from chronic cystitis for years has been restored to health after he had fallen into the hands of a surgeon who took the pains to search for, find, and remove a calculus which had never been suspected by previous advisers. TJie treatment of ehrojiic cystitis should never be begun until a most thorough ond searching ex- amination has been made for the cause. The prostate is responsible for a large proportion of all cases. A digital examination by the rectum will speedily settle the question as to whether the gland is enlarged. A vesical calculus will manifest its presence by the symptoms peculiar to stone, and the bladder should be searched for stone. Urethral stricture is another cause which should receive careful attention. It is readily recognized by the diminished or forked stream THE GENITO-URINARY SYSTEM. 385 of urine, difficulty in micturition, and by examination with the urethral sound or catheter. The general treatment may be summed up under the following heads : 1. Remedies administered internally or by the rectum. The drugs which have found most favor in the treatment of chronic cystitis are buchu, pareira brava, oil of sandalwood, balsam of copaiba and cubebs, uva ursi, etc. Quinin, salol, and boric acid are valuable on account of their power to disinfect the urine and prevent the growth of micro- organisms. 2. Irrigation. Washing- the bladder with warm sterilized water or boric-acid solution is very important, after which the organ is ready to receive an injection of one or other of the solutions mentioned in the following paragraph. 3. Injections. Of all the remedies used for injecting the bladder, nitrate of silver must take the first place. Nothing will act more Fig. 163. — Keyes' irrigator for bladder. promptly in destroying the bacteria, and its action upon a chronically inflamed mucous membrane is superior to anything else. The bladder is first washed out with sterilized water. Two ounces of water holding five grains of nitrate of silver are then allowed to flow into the bladder and out again, after which the bladder is again washed out with steril- ized water. Other solutions which are recommended for irrigation are the following : boric acid of a strength of 5 to 10 per cent. ; bichlorid of mercury, i : 10,000; permanganate of potash, 3 per cent. ; carbolic acid, I : 500. The method of irrigating the bladder is shown in Fig. 163. It consists of a rubber bottle {A) which holds about a pint and can be suspended at a height of three or four feet above the level of the patient's bladder ; a rubber tube (i>) five feet in length, ending in a 25 386 SURGICAL DIAGNOSIS AND TREATMENT. Stop-cock ({T), which directs the fluid into the catheter {D) or the outlct-jMpc (A). The apparatus is used as follows : Fill the reservoir and hang it up ; open the stop-cock to allow the fluid to expel the air from the tubing; then pass the catheter. Turn the stop-cock (6^) to allow the fluid to enter the bladder, and when the viscus is full reverse the tap and allow the fluid to escape from bladder and run into the receptacle (4). By alternating this action the bladder is repeatedly filled and emptied. A simpler contrivance is a glass funnel connected with a catheter by means of a rubber tube two feet in length. The funnel is elevated and the fluid poured into it, which by gravitation reaches the bladder. By lowering the funnel below the level of the patient's pelvis the fluid escapes. The objection to this method is that it allows air to enter the bladder. Drainage. — In spite of the most persevering efforts in the use of these remedies some cases will show no improvement. Another resource is still open to the patient, which gives not only a fair prospect of relief from pain and constant urination and tenesmus, but a possi- bility of perfect cure. This is perineal cystotomy. By means of it the bladder can be thoroughly drained, and the irrigations and injections given a better opportunity to exert their full benefit upon the inflamed surface. Stone in the Bladder. — In its normal condition urine contains about 90 per cent, of water in which are dissolved 10 per cent, of organic and inorganic materials. The organic substances are urea and uric acid. Of these, uric acid plays an important part in the formation of calculi, for, although it exists in the proportion of only i to looo in the urine, it enters into the formation of a great majority of vesical calculi. The inorganic constituents are sodium, potassium, and magnesium, bases with which uric acid unites. These bases also unite -with sulphuric and phosphoric acids to form corresponding salts. Nor- mal urine also contains chlorids, mucus, and epithelium. While these substances are held in solution all is well. When they form deposits and their particles aggregate around a nucleus, stone is the result. In the majority of cases uric-acid crystals form the nucleus, the crystals being held together by the renal or vesical mucus. A drop of dried blood or a foreign body in the bladder, as a piece of catheter or a fragment of bone, is sometimes the nucleus. Nuclei composed of uric acid or of oxalate of lime are found in the kidney, and increase in size as they lie in the renal pelvis or the bladder. When composed of the triple phosphates the calculi begin to form in the bladder and owe their origin to ammoniacal urine. The examination of a patient for urinar}^ calculus may be considered under the following heads : History. — A large proportion of cases of bladder-stone will be found to have had their origin in the kidney. The passage of the stone thence to the bladder is marked by an attack of renal colic, and the patient will probably give a. graphic description of a terrible attack of pain which occurred weeks or months previously, and which was followed by freedom from suffering until the bladder began to give trouble. Chronic cystitis should excite suspicion of stone, for it may THE GENITO-URINARY SYSTEM. 387 either be the result or the cause of a calculus. The irritation set up by a stone invariably produces cystitis. The existence of cystitis, on the other hand, is attended with copious secretion of mucus or muco- pus, affording the colloid material which binds together the particles that form the nucleus of a stone. Enlargement of the prostate is another powerful predisposing cause, owing to the changes which take place in the urine and in the bladder as a result of obstruction to the flow of urine and the consequences of that obstruction — viz. atony and retention. For similar reasons inflammation or catarrh of any part of the urinary tract is a predisposing cause of stone. Persons who have been sufferers from gout or rheumatism are liable to stone, and a history of one or other of these diseases should arouse our suspicion. As regards age, childhood and advanced life afford the largest num- ber of cases. Children suffer from uric-acid, old men from phosphatic, calculi. Females on account of the shortness of the urethra and the freedom from causes of obstruction rarely suffer from stone in the bladder. Symptoms Indicating the Presence of Stone. — Frequent micturi- tion is generally the first symptom to draw the patient's attention to the fact that something is going wrong. At first he may be called to urinate once in three or four hours, the frequency gradually increasing until he is compelled to empty his bladder every few minutes. This symptom is more marked in children than in those advanced in years. It is in- creased by exercise, by walking or running, by riding on horseback or in a jolting vehicle. As might be expected, the patient is much better during the hours which he spends in bed. A small stone moves freely in the bladder with every change in the position of the patient's body, while a large stone may form for itself a bed in the floor of the bladder and be subject to very little movement. This explains the clinical fact that not only frequent micturition, but pain, is often more marked when the calculi are small. Sudden arrest of the floiv of 2irine is a symptom of great value. It is most marked when the stone is small, and during micturition rolls into the mouth of the urethra or the neck of the bladder, forming a ball valve and obstructing the flow. Many patients by painful expe- rience learn to alleviate this by assuming an attitude which keeps the stone well away from the urethral opening. Pain. — It is possible for a good-sized stone to exist without causing much pain, but this is very exceptional. If the stone is firmly imbedded in a vesical pouch or coated with a colloid material which covers up its rough points and gives it a smooth, soft surface, it may produce little irritation. As an almost invariable rule stone in the bladder is attended with intense suffering. The pain has two characteristics : {a) It is felt at the under surface of the penis near the meatus. This is why little boys with stone in the bladder keep up a constant pulling of the pre- puce till it becomes greatly elongated and inflamed, {li) The period of greatest intensity is at the end of micturition. The bladder contracts upon the stone, and woe betide the poor sufferer if the surface of the calculus is rough, hard, and nodular, as is generally the case when it is composed of oxalate of lime ! Firmly closing upon the stone, the bladder may hold its grip until the slowly collecting urine comes be- 388 SURGICAL DIAGNOSIS AND TREATMENT. tween it and the stone and affords a brief respite. Distal pains of reflex character are not uncommon. The rectum and perineum are most liable to suffer, but parts more remote are sometimes affected, as the lungs, the stomach, the extremities, the back, and the thighs. Hematuria is a symptom frequently observed, and is a natural con- sequence of the rough treatment to which the mucous membrane is subjected by the presence of a stone. It is most marked when the patient takes exercise or is subjected to jolting, as in travelling. The character of the urine is worthy of attention. It is generally loaded with muco-pus, but, as this simply indicates cystitis, it is not of much value from a diagnostic standpoint. The passage of small calculi, the so-called " gravel," is much more significant. The symptoms just mentioned are not sufficient to base a diagnosis upon. Their presence in whole or in part simply warrants us to proceed to the third part of the investigation — viz. : Sounding the Bladder. — We cannot introduce the finger into the bladder, so we use a long, slender metallic finger called a sound. This instrument should have a straight shaft, a flat handle, and a short curve. It should be of the size of a No. 8 English or 13 French bougie. Two sizes are convenient — one having a slight curve (Fig. 164), the other Fig. 164. — Harrison's searcher. having a short, abrupt curve for the purpose of searching the part just behind the prostate, and which is likely to be the hiding-place of a stone. The indications for resorting to the use of bladder-sounds are thus laid down by Reginald Harrison : 1. "In children suffering from vesical irritability, incontinence of urine, sudden interruption to micturition, retention of urine, blood in the urine, penile irritation inducing the pulling of the foreskin, and prolapse of the bow^el. 2. " In the vesical irritability of adults after attacks of renal colic, where there are reasons for believing a calculus may be retained in the bladder; in cases of hematuria of a doubtful nature, or of chronic muco-purulent or ammoniacal urine, or where the urine contains on standing an excess of cloudy mucus. 3. " In pain after micturition referred to the end of the penis. 4. " In the enlarged prostate of elderly persons, with persisting^ symptoms of vesical irritability. 5. " Where calculi or portions of them have been spontaneously passed and symptoms of irritation continue. 6. " In cases of acute vesical spasm terminating the act of micturi- tion, or where, though the bladder contains but little urine, there is frequently a sudden and uncontrollable desire to micturate. " Though the indications of stone may be numerous, it will be seen that they all have reference to either a persisting source of irritation THE GENITO-URINARY SYSTEM. 389 within the bladder or a mechanical interference with the act of mic- turition." The operation of sounding for stone is not to be lightly undertaken, and, when employed, the patient should be as carefully prepared as for a major cutting operation. If he has just completed a long journey by rail or carriage, time should be given him to rest and to allow the bladder to recover from the irritation consequent to the jolting move- ment inseparable from such a journey. The history and present con- dition of the patient should be thoroughly gone into, and a specimen of his urine taken for chemical and microscopic examination. The bowels should be emptied, and just before the passage of the instru- ment the urethra should be washed out with a mild antiseptic solution. None but a slovenly or antiquated practitioner would use an instrument without having first boiled or otherwise disinfected it, and the operator's hands should be as carefully scrubbed as if about to begin a laparotomy. The patient should lie on a table ; his knees should be drawn up to flex the thighs upon the abdomen, and the limbs should be slightly sepa- rated. The bladder should be moderately filled, either by injecting it with warm boric-acid solution or by having the patient retain his urine for several hours previous to the examination. Passing the Soiuid. — The instrument, having been disinfected by boiling, is dipped in sterilized olive oil, and while still warm is passed into the bladder in the following manner : Stand at the patient's left side ; hold the sound in the right hand and take the penis between the thumb and fore finger of the left. Put the organ gently on the stretch in such a position that the dorsum faces the abdominal wall, with the urethra free from kinks or twists. Insert the end of the sound into the urethra, keeping the instrument parallel to Poupart's ligament. The handle is held low and the penis gently stretched while the instrument is passed in to about the membranous portion of the urethra. Sweep the handle round to the middle line of the body, still keeping close to the abdomen ; then press the instrument gently downward toward the feet and make slight traction upon the penis. The instrument should glide a few inches farther in this direction ; when it stops raise the handle, keeping it exactly in the middle line, and, passing the perpen- dicular, depress it between the thighs. During the time that the right hand is describing this arc of a circle the fingers of the left hand are shifted to the perineum beneath the scrotum, where they aid in direct- ing the sound through the membranous and prostatic portions of the urethra into the bladder. Sometimes it will be found better to take the instrument in the left hand just after it has passed the perpendicular, and to use the index and middle fingers of the right hand, placed on each side of the root of the penis, to make downward pressure. Searching for Stone. — Having now inserted the sound, a careful search must be made, not by pushing the instrument about on a happy-go-lucky chance of striking against a stone, but in a systematic manner. We know that the sound is in the bladder by the freedom with which we can move the tip of the instrument when we rotate the handle, and by the instrument remaining in the middle line and point- ing away from the pubis when the hand is removed. The middle line should first be explored by slightly withdrawing and replacing the 39° SURGICAL DIAGNOSIS AND TREATMENT. sound, raising and depressing the handle. It should then be rotated so as to make the tip of the instrument turn to one side, and as it is slowly and gently pushed in and out the curve is made to feel the floor of the ca\ity to both right and left of the middle line. It may be that in all these maneuvers no stone is felt, and yet the sound repeatedly passes over it. This is because the calculus is lying in a pouch on the bladder-floor just behind the prostate, and the instrument with a slight curve fails to touch it. This possibility should always be taken into account, and, failing to find a stone with the first sound, a second instru- ment with a short, abrupt curve should be employed and the search renewed. It is not advisable to state positively that the patient has no stone in the bladder on the data obtained from one examination. A second examination a few days later will perhaps yield different results, as many surgeons have found by experience. The presence of a stone is recognized by the sensation com- municated to the hand when the sound strikes a hard body, and by the Fig. 165. — Diagnosis of calculus (Fenwick). peculiar chck which can generally be distinctly heard. To magnify this " click " a stethoscope can be placed over the hypogastrium, or one end of a rubber tube can be attached to the bladder-sound and the other end applied to the examiner's ear. As aids to the examination the following procedures may be mentioned : The anterior wall of the bladder can be brought within reach of the sound by the surgeon pressing upon the abdominal wall. A finger in the rectum can be used with advantage to raise the bas-fond of the bladder and bring it in contact with the sound. In cases of enlarged prostate a stone is apt to lie hidden behind the gland and thus elude the searcher ; raising the hips or placing the patient in the Trendelenburg position will cause the stone to roll back toward the fundus. In the case of very small stones a hollow sound is useful. By means of it a portion of the bladder- contents can be removed while the patient is standing upright, and, if the sound be slowly withdrawn and turned from side to side until it comes to the neck of the bladder, the calculi, however small they may THE GENITO- URINARY SYSTEM. 391 be, are sure to come in contact with the instrument. Bigelow's evacuator and wash-bottle sometimes succeed in finding and removing a small stone which cannot be felt with a sound. For the detection of stones lying in a deep post-prostatic pouch E. Hurry Fenwick recommends plunging a long trocar and cannula into the suprabubic region and directly backward to the stone (Fig. 165). Examination by the Cystoscopc. — In doubtful cases the use of the cystoscope in skilful hands is of great value. Leiter's cystoscope (Fig. 166) is of the shape and size of a No. 21 F. sound. At the extremity Fig. i66. — Leiter's cystoscope. it carries an Edison incandescent lamp enclosed in a cup having a small aperture fitted with a plate of rock cystal. Two conductors passing within the shaft connect with the little sockets for the lamp and com- plete the circuit. The bend of the instrument contains a prism. To make use of the cystoscope the patient should be placed in the dorsal or the lithotomy position. The bladder ought to contain six to eight ounces of clear urine. Should the urine be turbid, wash out the blad- der and inject boric-acid solution ; if the urine is tinged with blood, irrigate the bladder with equal parts of extract of hamamelis and hot water. Anesthesia may be local or general or may be dispensed with. Should cocain be employed, it must be kept in mind that fatal results have followed its use, although Fenwick says that he has injected a dram or more of a 20 per cent, solution and never saw any evil effects. Having tested the lamp to ensure its being in working order, the instru- ment is introduced and carefully moved about, to be sure that the beak is not in contact with the bladder-wall. First the beak is directed up- ward, and then turned from side to side till all parts of the bladder come into view except the trigone. The handle is then lowered and the position of the beak reversed, bringing within the field of vision the trigone and the orifices of the ureters. In its normal condition the mucous membrane of the bladder is of 392 SURGICAL DIAGNOSIS AND TREATMENT. a yellowish or reddish-yellow color. Its blood-vessels are tortuous and ^ " • ■ • 30 to 32 3^ " 32 to 34 4 " 34 to 36 This table, however, must not be looked upon a.s strictly accurate : the circumference of the penis is subject to considerable change, and a too rigid adherence to the theory would result in the passage of a sentence of stricture on almost every urethra. If the meatus is ab- normally small, it must be incised by means of a probe-pointed knife. The instrument first selected should be of moderate size, .say 15 to 16 Fr. ; if this can be passed without resistance, No. 20 or 21 may be tried. If you succeed in passing this without resistance, you may reasonably infer that there is no stricture. A source of error must be guarded against in this examination, for it frequently happens that as soon as the bulb of the instrument passes the fossa navicularis it is grasped by spasmodic action of the urethra and firmly held ; in a minute or two the muscular fibers become fatigued and the bulb can be passed onward without resistance. This spasm may occur at any part of the urethra, and is most apt to take place in patients who are examined for the first time, or in those of nervous temperament, or in those who are the subjects of uric-acid diathesis. If the bulb meet with sudden resistance (which is not due to spasm Fig. 186. — Weir's urethrometer. of the urethra) and cannot be passed farther, it should be withdrawn, and smaller sizes introduced until one is found which will pass the stricture with only slight resistance. The position of the stricture is now carefully noted. 2. The length of the stricture. By passing the bulb beyond the stricture, and then withdrawing it, the base of the cone can be felt to catch against the limit of the stricture farthest from the meatus. The nearest point has already been ascertained, and the distance between the two will represent the length of the stricture. In many cases the resistance of the stricture can be felt during its whole length as the instrument is withdrawn. 3. The degree of contraction or size of the stricture. This can be estimated by the size of the bulb which can be passed with a slight resistance, but more accurately by the urethrometer of Otis, Weir (Fig. 186), or Gross. 4. The number of strictures. This may be difficult to determine by the aid of bougies, but the urethrometer, being adjustable to the caliber of each contraction, is the proper instrument by which to solve the question. THE GENITO-URINARY SYSTEM. 437 5. The condition of the urethra behind the stricture. As the bougie is withdrawn it carries with it the urethral secretion which collects against the shoulder of the bulb, an examination of which will afford some idea of the state of the urethra. Classification of Organic Strictures. — For convenience in selecting a mode of treatment strictures are divided according to the degree of contraction into — 1. Those of lage caliber. No. 15 French is taken as the limit; any stricture which admits a larger bougie is said to be of large caliber. 2. Those of small caliber (less than No. 15 French). 3. Strictures permeable only to filiform bougies. 4. Impassable strictures. In reference to the situation, the following classes are convenient : 1. At the meatus or fossa navicularis. 2. In the pendulous portion of the urethra. 3. In front of the bulbo-membranous junction. 4. At or behind the bulbo-membranous junction. Treatment. — Before considering the surgical procedures which have been devised for relief of stricture attention should be paid to some points in the general treatment which have much to do with the success of operative procedures. The patient who is the subject of a stricture should pay the closest attention to sexual and genito-urinary hygiene. Exposure to cold should be avoided, as well as everything approaching excess in eating and drinking. When cystitis is present, as is frequently the case, this condition must be treated and remedies used w^iich will prevent decomposition of the urine. Quinin, salol, salicylate of soda, naphthalin, boracic acid, and creasote are all useful drugs for this pur- pose. When retention of urine occurs it is usually due to spasm of the urethra and can be overcome by a hot bath. Operative Treatment. — Many modes of treatment have been devised and practised for the relief of stricture, a large proportion of which have been abandoned as barbarous, useless, and unscientific. The methods now in use and meeting with more or less general approval are — i. Gradual dilatation; 2. Continuous dilatation ; 3. Urethrotomy and dilatation combined; 4. Internal urethrotomy; 5. External urethrotomy with a guide; 6. External urethrotomy without a guide; 7. Electrolysis ; 8. Excision ; 9. Subcutaneous section. Let us now consider the operative treatment suitable for the various forms of organic stricture : 1. Stricture of the MeatJis. — The meatus may be abnormally con- tracted as a congenital malformation or it may be the result of disease. In either case the treatment consists in making an incision with a probe-pointed knife, the blade being directed downward and care being taken to divide the fibrous bands which are the cause of constriction. Bougies should be passed every second day after the operation to keep the orifice dilated until healing shall have taken place. 2. Stricture of the Pendulous Portion. — Gradual dilatation should be given a fair trial. Internal urethrotomy is with some authors the favor- ite operation for strictures in this portion of the canal. The opera- tion is almost free from the dangers which attend its use in the deep urethra, and if carried out under aseptic precautions these dangers may 438 SURGICAL DIAGNOSIS AND TREATMENT. practically be disregarded. And yet discretion is necessary in a choice of method even here. If the stricture be recent and soft, gradual dilatation may give good results, and should first be tried. If there be gleet or the stricture be unyielding, urethrotomy should be chosen, owing to its freedom from danger and the probability of its effecting a permanent cure. Internal urethrotomy combined with dilatation is a very satisfactory method of treatment, and can be well carried out by the aid of Otis's urethrotome. Whatever instrument is employed, the preparations for the operation should be aseptic in every detail. The urethra should be irrigated with a bichlorid solution of a strength of i : 10,000. The hands of the operator and the instrument should be as carefully dis- infected as in a major operation. It is not always necessary to employ general anesthesia, as a solution of cocain (4 per cent.) is sufficient. The incision is made in the roof of the urethra, and it is essential that all the strictured tissue be divided, from the normal urethra behind to the normal parts in front. In very small strictures a preliminary incision may be necessary. A filiform bougie is passed through the stricture to serve as a guide; over this a Maisonneuve urethrotome (Fig. 187) is \ Fig. 187. — Filiform whalebone bougies. passed through the stricture, and an incision made which allows the passage of a dilating urethrotome and division of the stricture from behind forward. About the third day the passage of sounds should be commenced to prevent recontraction during the healing of the wound. This should be repeated once or twice a week for six weeks or longer. Strictures at or behind the Bulbo-mcinhranous Jtinctioii. — These are the most difficult of all strictures to treat, for it may be laid down as an axiom that the seriousness of stricture increases with its distance from the meatus. When of large caliber, simple, and soft, gradual dilatation is indicated. Great care is necessary in the use of steel instruments, as the urethral mucous membrane is soft and easily lacerated. In treat- ment of strictures of small caliber the choice lies between dilatation and urethrotomy. Good results are obtained by using continuous dilata- tion for twenty-four or forty-eight hours, and gradual dilatation every second day thereafter. Traumatic strictures in this situation demand ex- ternal urethrotomy as a rule. Sometimes the stricture is so contracted as to render it impossible to pass a steel sound of any size. Filiform bougies are employed in such cases wath good effect. The opening may not be in the center of the stricture, but at some part of its circumference. If the filiform bougie cannot be passed, withdraw it and bend the point of it over the thumb-nail to an angle of 45°, as seen in Fig. 188. By persevering efforts the instrument can usually be made to enter the stricture, and when once passed it should be left there for twenty-four hours, when it will be found that others can be inserted by its side. THE GENITO-URINARY SYSTEM. 439 Having succeeded in passing a filiform bougie, the proceeding will vary according to circumstances. First, an attempt should be made to pass a tunnelled catheter or grooved staff over the filiform into the bladder, after which gradual dilatation can be employed. Or the fili- form can be used as a guide to a Maisonneuve urethrotome, and inter- nal urethrotomy performed, followed by gradual dilatation. In most cases, however, the best course is to use the grooved staff as a guide and perform external urethrotomy. In spite of the most persevering efforts it is sometimes impossible to pass ev^en a filiform bougie. A stricture of this kind is called impassable. The condition is attended with serious consequences. Retention of urine is complete, and in powerful efforts to force it through the stricture the urethra may give way and extravasation follow. The only remedy is perineal section or external urethrotomy without a guide. Extrav- asation of urine presents symptoms which depend upon the part of the urethra which has suffered the urine to escape through its walls. In the penile urethra the swelling will be found to extend from the meatus to the scrotum, and will be most marked at the seat of rupture. Rup- FlG. 188. — Maisonneuve's urethrotome. ture between the attachment of the scrotum and the anterior part of the bulb is late in showing itself by swelling ; the urine, being restricted by the deep layer of the superficial fascia, first appears in the scrotum, whence it escapes between the pubic spine and symphysis and reaches the abdomen. If the rupture lies between the two layers of the tri- angular ligament, the urine will be imprisoned until suppuration and sloughing allow it to break through and appear in some part of the perineum. In the prostatic urethra extravasation finds its way along the rectum to the perineum near the anus, or, passing through the pelvic fascia, it may spread through the subperitoneal connective tissue. Another result of extravasation is urethral fistula. The urine may escape drop by drop through a break in the urethral wall, and set up suppuration, resulting in an abscess which opens externally. Accord- ing to its location a fistula of this character is spoken of as urethro- penile, uretJiro-perineal, and itrethro-rectal. There is little or no dif- ficulty in the diagnosis, as the escape of urine through a fistulous opening is sufficient evidence. To corroborate this sign pass a steel sound into the bladder and probe the fistula from its external opening. In the vast majority of cases urethral fistulae are caused by strictures. The treatment consists in curing the stricture, after which the fistulous tract is laid open or curetted. During the healing process the urine is drawn off at regular intervals or a catheter is retained in the bladder. 440 SURGICAL DIAGNOSIS AND TREATMENT. External Urcthrotoiiy. — The operation of incising the urethra from without is indicated in complete retention due to stricture, in extravasa- tion of urine, and in several forms of stricture as already described. The terms external urethrotomy with a guide and external urethrotomy without a guide are self-explanatory. The term perineal section is best reserved for those cases which are impermeable to all instruments. Operation ivith a Guide. — To the late Prof Syme is due the credit of reviving this operation, and its performance has been greatly facil- itated by the staff which he invented as a guide (Fig. 189). It consists — Syme's staff. of a sound having two parts of different diameters ; for the last two and a half inches it is of the size corresponding to No. 2 English, and this portion is grooved on its convexity. The rest of the staff is equal in size to No. 10 English. At the junction of the two parts there is a shoulder which is intended to rest on the face of the stricture. The instrument is passed carefully along the urethra and the slender por- tion through the stricture, the finger meanwhile inserted into the rec- tum to guard against the making of a false passage. The staff is then given to an assistant, who holds it steadily and during the incision presses the convexity of the instrument downward against the peri- neum. The patient is placed in the lithotomy position. The operator inserts his left fore finger into the rectum, and, cutting exactly in the middle line, makes an incision about an inch in front of the anus and cuts down upon the groove in the staff. Having found this, he uses it as a guide and freely divides the stricture. Through the perineal wound a grooved director or gorget is passed into the bladder and the staff removed. The next step is to pass a full-sized catheter by the urethra into the bladder, the grooved director or gorget (Fig. 190) serving as a Fig. 190. — Teale's probe-gorget. guide. If the bladder will tolerate it, the catheter can be retained, but this is not necessary. At the end of a week a full-sized bougie a boule should be passed, keeping close to the roof of the urethra. This is rendered painless by the injection of a 4 per cent, solution of cocain. THE GENITO-URINARY SYSTEM. 44 1 and should be repeated every second day for the first week, after which the intervals may be gradually lengthened. Operation witJiout a Guide. — When a stricture is impermeable even to a filiform bougie, the operation of external urethrotomy without a guide is indicated. The operation of Wheelhouse of Leeds is the best. A special staff is employed which has a groove throughout its entire length except the last half inch (Fig. 191). The operation is thus described in the eminent surgeon's own words : " The patient is placed in the lithotomy position, with the pelvis a little elevated, so as to let the light fall well upon it and into the wound to be made. The staff is to be introduced with the groove looking toward the surface, and brought gently into contact with the stricture for fear of tearing the tissues of the urethra and causing it to leave the canal, which would mar the whole after-proceedings, which depend upon the urethra being opened a quarter of an inch infron{ of the stricture. Whilst an assist- ant holds the staff in this position an incision is made into the perineum, extending from opposite the point of reflection of the superficial peri- neal fascia to the outer edge of the sphincter ani. The tissues of the perineum are to be steadily divided until the urethra is reached. This is now to be opened in the groove of the staff, not upon the point, so as certainly to secure a quarter of an inch of healthy tube immediately in front of the stricture. As soon as the urethra is opened and the groove in the staff fully exposed, the edges of the healthy urethra are to be Fig. 191. — Wheelhouse's staff. seized on each side by the straight-bladed nibbed forceps and held apart. The staff is then gently withdrawn until the button point appears in the wound. It is then to be turned around so that the groove may look to the pubes, and the button may be hooked into the upper angle of the opened urethra, which is thus held stretched open at three points — at two by the forceps, and at the third by the hook of the staff. The operator looks into it immediately in front of the stricture, inserts the director into the urethra, and, if he cannot see the opening of the stricture, which is often possible, generally succeeds in very quickly finding it, and passes the point onward through the stricture toward the bladder. The stricture is sometimes hidden among a crop of granulations or warty growths, in the midst of which the probe point easily finds the true passage. The director having been passed on into the bladder (its entrance into which is clearly demonstrated by the freedom of its movements), its groove is turned downward ; the whole length of the stricture is carefully and deliberately divided on its under surface, and the passage is then cleared. The director is still held in the same position, and the straight probe-pointed bistoury is run along the groove to ensure complete division of all bands or other obstruc- tions. These being thoroughly cleared, the old difficulty of directing the point of a catheter through the divided stricture is to be overcome. To effect this the point of the probe-gorget is introduced into the groove of the director, and, guided by it, is passed onward into the 442 SURGICAL DIAGNOSIS AND TREATMENT. bladder, dilating the divided stricture and forming a metallic floor along which the point of the catheter cannot fail to pass securely into the bladder. The short catheter is now passed from the meatus down into the wound ; is made to pass once or twice through the divided urethra, where it can be seen in the wound, to render certain that no obstructing bands have been left undivided, and is then, guided by the probe- dilator, passed easily and certainly along the posterior part of the urethra into the bladder. The gorget is now withdrawn, the catheter fastened in the urethra and allowed to remain three or four days, the elastic tube conveying the urine to a vessel under or by the side of the bed. After three or four days the catheter is removed, and is then passed daily or every second or third day according to circumstances until the wound in the perineum is healed, and after the parts have be- come consolidated it requires to be passed still from time to time to prevent recontraction." Great difficulty is sometimes experienced in finding the proximal end of the urethra, especially in traumatic strictures. If the bladder contain considerable urine and pressure be made over it, a jet of the liquid may reveal the opening of the urethra. The same result may be obtained by bimanual palpation, with the fingers of one hand over the bladder and those of the other hand in the rectum. Failing in this, the parts should be douched with hot water, when the urethra will become prominent by its being paler than the other tissues. Every effort to find the urethra having proved futile, the best way out of the difficulty is to perform a suprapubic cystotomy and make retrograde dilatation. CJioicc of Operation. — Gradual dilatation is the simplest and safest operation, and is generally successful. It may fail in tight strictures close to the meatus, and then internal urethrotomy should be resorted to. Tight strictures of the bulbo-membranous region may resist all efforts at gradual dilatation ; external urethrotomy is then to be chosen, especially if the stricture is of traumatic origin. Impassable strictures leave no choice, and must be treated by external urethrotomy. Urinary Pouches. — A stricture or the presence in the urethra of a calculus sometimes causes a pouching or rupture of the urethra behind the obstruction, and the formation of a reservoir which holds a quantity of urine that is not expelled in micturition. This condition may be mistaken for urethral abscess, the preliminary to urethral fistula already mentioned. Symptoms. — Urinary pouches appear as round or ovoid tumors along the course of the urethra. There is absence of pain and redness, but there is fluctuation. The swelling becomes more tense and promi- nent during the act of micturition, after which it is more relaxed, but does not disappear. The patient, having learned by experience that the tumor can be prev^ented from filling, makes pressure with the fingers of his right hand while he holds the penis in the left during urination. The urine which remains in the pouch in spite of this or other precautions dribbles away later on, soiling the clothing of the patient and causing great annoyance. In some cases the urethra is merely dilated, and then the urine contained in the pouch is always normal ; in another class of cases there is a breach of continuity in THE GENITO-URINARY SYSTEM. 443 the urethral wall ; a pouch forms in the same manner, but the urine is likely to contain pus or blood, and frequently ends in urinary fistula. Treatment. — When the urethra is simply dilated the whole treatment must be directed against the obstruction which is the cause of the pouch. A calculus if present must be removed or a stricture remedied. When there is perforation of the urethra it is sometimes sufficient to retain a catheter and use mild compression externally. When there is an abscess it should be opened, and a catheter kept in the urethra to prevent the formation of a fistula. VI. INJURIES AND DISEASES OF THE MALE GENERATIVE ORGANS. Diseases and Malformations of the Penis. The meatus, instead of opening in its normal position, in very rare cases is found to open at the side or in the dorsum of the penis. In absence of the bladder the ureters have been found to empty into the urethra, and the rectum has in very rare instances been known to have a similar outlet. These malformations are of little practical value, but there are two others which require more extensive notice — viz. hypospadias and epispadias. Hypospadias is a malformation the distinctive feature of which is an absence of the lower wall of the urethra, so that the canal opens on the under surface of the penis. The opening may be in the glans or in the spongy portion, or the urine may be expelled at the scroto-perineal junction. When the hypospadic opening is at the scroto-perineal junction there is a fissure in the scrotum, giving it the appearance of the external genitalia of the female ; the penis is bound down to the fissure and may be very much atrophied. In the penile variety the opening maybe at any point on the floor of the pendulous urethra, and an almost constant complication is a downward curvature of the penis. An opening within an inch of the normal position of the meatus may be attended with little inconvenience, and requires, as a rule,- no treat- ment, but a penile, scrotal, or perineal hypospadia is one of the most distressing of abnormalities and requires operative interference. Of the diagnosis there is little to be said, as the condition is self- evident. Treatment. — Several operations have been devised, but the method of Duplay is the only one that has met with success. It consists of three stages : 1. Straightening the Penis. — This is done by making a transverse incision of the ridge which unites the hypospadic opening to the glans, the incision being carried to a depth which will secure complete straightening of the penis (Fig. 192, A). In this incision it may be necessary to go deeply into the corpora cavernosa, but this can be done without risk. When the organ is straight or but slightly curved this step of the operation is not necessary. 2. TJie Formation of a Nezv Canal from the Meatus to the Hypospadic Opening. — The first point to demand attention is the formation of a meatus. The position of this opening is indicated by a depression in the 444 SURGICAL DIAGNOSIS AND TREATMENT. glans penis. The two lips of this depression are vivified as in F'ig. 192, B. Between them is placed the tip of a catheter, and over this the edges of the freshened surfaces are secured by several catgut sutures. If the depression is too shallow, more room can be gained by making A B Fig. 192. — Duplay's operation for hypospadias (Duplay and Reclus). two small lateral incisions, a, a', or a single median incision in the sub- stance of the glans. Next comes the formation of the new canal. Along the lower surface of the penis on each side of the middle line two incisions are made from the corona glandis to within a quarter of an inch of the hypospadic opening (Fig. 193). The internal lip at a d is dissected up and turned inward over the catheter, but not entirely covering it. The ex- ternal lip, r, d, c', d' , is freely dissected so as to separate the skin from the subjacent tissues, and so as to allow the skin of the sides of the penis to be drawn toward the middle line. The cutaneous surface of the lips at a' b' are turned toward the cavity of the canal, and their raw surfaces toward the outside and covered by the raw surfaces of the outer flaps. The edges of the flaps are united in the middle line by quilled sutures of silver wire, silkworm gut, or silk, and fastened with perforated shot. 3. Jimctiojiof tlic Tivo Portions of the Canal. — This consists in closing the fistulous opening which still remains at the hypospadic orifice by freshening the edges and bringing them together by quilled sutures over the catheter. A retained catheter is employed to carry off the Fig. 193. — Transverse section of the penis after operation : S, the new ure- thra (Duplay and Reclus). THE GENITO-URINARY SYSTEM. 445 urine during the healing process. The whole process of the cure of hypospadia is long and tedious. Three, four, or five operations may be necessary, and the treatment may extend over six or eight months. Hpispadias is a much rarer abnormality, and consists in a de- ficiency of the upper wall of the urethra. The operation for its cure is similar to that just described. Phimosis is characterized by an unnaturally elongated condition of the prepuce, with so small an opening that it is impossible to uncover the glans. The condition may be congenital or acquired. The acquired form has already been described as a complication of balanitis and balano-posthitis. The congenital variety is important on account of the continual irritation kept up by it, leading in extreme cases to chorea, •epilepsy, and other nervous affections. The glans is often adherent to the prepuce in whole or in part ; the preputial orifice is usually small, sometimes little larger than a pinhole, and during micturition the pre- puce become distended with urine. The secretion collects inside, and the danger of infection is greatly increased should the patient be exposed to venereal diseases. Treatment. — When a corona glandis cannot be completely exposed without difficulty circumcision should be performed. The parts having been carefully disinfected, the prepuce is drawn well forward and grasped by a pair of forceps in front of the anterior extremity of the glans. The blades of the forceps should be an inch and a half in length, so as to grasp the whole width of the prepuce. With ordinary care there is no risk of wounding the glans, although this has happened in the hands of incompetent operators. With a sharp knife the foreskin in front of the forceps is removed. The prepuce is now allowed to retract, when it will be found that while the skin recedes to the corona or behind it the mucous membrane forms a hood over the glans. This membrane is slit in the middle line up to the corona, and then cut off all around at a distance of one-sixteenth of an inch from the point of reflection. This will be found to follow the line of the corona. The frenum should be spared unless there is marked hypertrophy at that point. The edges of the skin and mucous membrane should be approximated by inter- rupted catgut sutures. The most convenient dressing is a thin layer of absorbent cotton covering the incision and sealed over with iodoform- ized collodion. The end of the penis can be protected from irritation by absorbent cotton and a T-bandage. Paraphimosis. — Should the glans be forced through a prepuce too narrow to admit it, constriction is sure to follow. The glans becomes swollen, congested, and edematous ; the orifice of the pre- puce forms a constricting ring, while the part of the prepuce behind falls forward like an edematous collar. Unless relieved, this condition ends in ulceration and sloughing. The glans should be pushed back in the manner described under Phimosis due to Gonorrhea. Failing in this, a director should be passed beneath the constricting ring and the constriction divided. Carcinoma of the Penis. — Epithelioma of the squamous variety is the only form found upon this organ. It begins as a warty growth upon the glans or the inner surface of the prepuce, and it is said that phimosis is a predisposing cause. The wart soon breaks down and forms 446 SURGICAL DIAGNOSIS AND TREATMENT. ail ulcer with very hard margins. The disease rapidly spreads by infil- tration of the surrounding parts, and sooner or later the corpora caver- nosa, the glans, and, secondarily, the lymphatics of the groin, become involved. The only disease with which it is liable to be confounded is syphilis. The ulceration of epithelioma is recognized by attention to the following points : 1. It is a chronic ulcer, with an irregular hard base and a foul, watery, or bloody discharge. 2. The growth infiltrates the tissues of the penis, and at the same time grows from its surface. 3. Antisyphilitic treatment has no effect upon the disease. 4. The inguinal glands become involved sooner or later, 5. Microscopic examination shows cancerous elements. TrcatDioit. — The only remedy is amputation, and in view of the rapidity of the growth this treatment should be resorted to at an early period. The operation was formerly done by a simple sweep of the knife, or at most by the formation of a flap of the skin to cover the surface of the wound. This method was followed by stricture of the orifice of the urethra and frequently by recurrence of the disease. The best results are obtained by amputation of the entire penis, and the operation of Pearce Gould is now generally adopted. The method of its performance is thus described by Treves : Operation. — " The patient having been placed in the lithotomy posi- tion, the skin of the scrotum is incised along the whole length of the raphe. With the finger and the handle of the scalpel the two halves of the scrotum are then separated quite down to the corpus spongiosum. A full-sized metal catheter is now passed as far as the triangular ligament^ and the knife is inserted transversely between the corpora cavernosa and the corpus spongiosum. " The catheter having been withdrawn, the urethra is cut across. The deep end of the urethra is then detached from the penis quite back to the triangular ligament. An incision is next made around the root of the penis continuous with that in the median line ; the suspensory ligament is divided and the penis separated, except at the attachment of the crura. The knife is now laid aside, and with a stout periosteal elevator each crus is detached from the pubic arch. This step of the operation involves some time, on account of the very firm union of the parts to be severed. Four arteries — the two arteries of the corpora cavernosa and the two dorsal arteries — require ligature. " The corpus spongiosum is slit up for about half an inch, and the edges of the cut stitched to the back part of the incision in the scrotum. " The scrotal incision is closed by sutures, and a drainage-tube is so placed in the deep part of the wound that its ends can be brought out in front and behind. No catheter is retained in the urethra. " In Gould's case — the operation was performed for epithelioma in a man aged seventy-three — there was no complaint of pain after the operation. The temperature reached the normal line on the fourth day, and on the sixth day the patient had regained complete control over the bladder. The skin-wound healed by first intention, the deeper THE GENITO-URINARY SYSTEM. 447 wound by granulation. The parts were completely healed in forty-six days." Diseases of the Scrotum. Bdema and Inflammation. — Owing to the looseness of the tissues which form the scrotum, swelling may occur rapidly and attain an enormous size. Edema is recognized by its doughy feel, by its pitting on pressure, by the disappearance of the normal scrotal folds, and by the glossy character of the skin. It is commonly the result of dropsy in the lower extremities due to cardiac or kidney disease, but it may follow any acute inflammation of the part. Inflammation of the scrotum is common, but, like inflammation in other loose tissues, such as the eyelid, the swelling is out of proportion to the other symptoms, and need give no great uneasiness, as it is likely to disappear as rapidly as it came on. The most serious form of scrotal inflammation is that due to extravasation of urine. This is about the only form which is really dangerous, and it demands the most prompt and vigorous treat- ment of the extravasation. Eczema and the irritation of dribbling urine are also common causes of mild forms of inflammation. Kpithelioma of the scrotum differs little from this form of carci- noma in other situations. In the scrotum, however, it is almost invari- ably due to a definite cause — the irritation of soot, hence the name " chimney sweep's cancer." It appears as a wart with hard edges raised above the surrounding skin and irregular in shape. It spreads from the margin and ulcerates in the center. In the early stages it is confined to the skin and is freely movable, but later it becomes attached to the deeper tissues, spreads to the glands of the groin, and involves the penis. Removal of the growth by operation is very satisfactory if resorted to in time. It would be wisdom to remove any warty growth with hard edges and showing a disposition to spread. Even after the disease has invaded the glands removal is followed by a good percentage of recoveries. Elephantiasis of the scrotum is common in some Eastern coun- tries as elephantiasis Arabian. It is characterized by enormous hyper- trophy of the skin and subcutaneous cellular tissue. It is often associated with repeated attacks of inflammation, such as attend urinary fistula, or it may depend upon lymphatic destruction and inflammation. From the scrotum it may extend to the penis, but never to the testicles. Swellings of the Scrotum. — There is no part of the body in which so great a variety of swellings is met with as in the scrotum. In most of the cases presenting themselves for examination the patients consult the surgeon for the purpose of ascertaining the nature of some enlargement of these parts. A systematic examination should cover the following ground : A. The swelling is confined to the scrotum. It is either edema, ele- phantiasis, epithelioma, or other tumor. Edema is associated with dropsy of the lower extremities, but it may be a result of extravasation of urine. Elephantiasis is a tropical disease, or it may be the result of repeated attacks of inflammation. Tumors found in connection with the scrotum are lipoma and epithelioma ; other growths are rare. 448 SURGICAL DIAGNOSIS AND TREATMENT. B. The swelling is connected with the testicles or their coverings. It must be one of the following : orchitis, malignant disease, benign tumor, hydrocele, hematocele. C. The swelling is connected with the spermatic cord. It is either an inflammation, a hydrocele of the cord, a varicocele, or a tumor. Orchitis, or Inflammation of the Testicle. — This is easily rec- ognized by pain, tenderness to touch, and its association with trau- matism, gonorrhea, tuberculosis, or syphilis. It is convenient to divide orchitis into two varieties, acute and chronic. Acute orchitis is gen- erally the result of traumatism, but may also be an extension of the inHammatory process from the epididymis or it may be metastatic, as in mumps. The pain is acute and the organ is very sensitive to the slightest touch. Swelling comes on rapidly, and the skin over the affected gland is red and glistening. Suppuration is not an uncom- mon result, especially in patients of low vitality. Treatment. — The pain is kept up and greatly aggravated by the weight of the testicle ; hence the first point in treatment is to support the scrotum and its contents by the use of a suspensory bandage or by a small pillow placed beneath the parts while the patient lies on his back. A brisk purgative often produces an immediate effect upon an acute orchitis, and should come in as a part of the routine treatment. In the early stages of the inflammatory process cold applications afford relief, especially in the form of lead-and-opium lotion ; later the same application as warm as can be conveniently borne will be more suc- cessful. When there is great tension and the case resists the above remedies, an incision should be made into the tunica vaginalis. Chronic orchitis is generally a complication of syphilis, and espe- cially if confined to the body of the testicle. In gonorrhea and tuber- culosis the swelling is likely to be confined to the epididymis. There is one character w'hich distinguishes the syphilitic testicle, and that is its weight. It is remarkably heavy as compared with the normal organ or with the weight of the organ under any other diseased condi- tion. Chronic orchitis of any kind is likely to produce atrophy of the testicle, or if suppuration begins the organ soon becomes riddled with sinuses and is finally destroyed. The diagnosis of chronic orchitis is very plain, but the variety of the inflammation — that is to say, whether it is syphilitic, tubercular, gouty, or malignant — is very necessary to determine. Syphilitic testicle has an even, smooth surface when the deposit is distributed through the whole of the fibrous tissue of the gland. The organ retains its normal shape, but it is enlarged, hard, and heavy. When the condition is due to a single gumma or several separate gum- mata the swelling is uneven and nodular. It comes on slowly, is free from pain, and generally attacks both testicles simultaneously. A his- tory of other manifestations of syphilis and the readiness with which the enlargement responds to antisyphilitic treatment need leave no doubt in the minds of the examiners. The form of testicular enlarge- ment with which it is most likely to be confounded is the gouty, but the previous history will usually be clear enough to differentiate them. Treatment. — lodid of potassium acts speedily upon the swelling up to a certain point, when improvement ceases and a hard mass remains THE GENITO-URINARY SYSTEM. 449 as a permanent deposit. Mercury cannot be applied to the scrotum, but has a very good effect when rubbed into the skin of the inside of the thigh. It can be given internally in the form of the bichlorid. When every other form of treatment has failed and the testicle is disorganized, it should be removed by castration. Tubercular Orchitis. — In many cases tuberculosis in the testicle is a manifestation of constitutional disease. The enlargement begins usu- ally as a hard nodule at the back of the testicle or in the epididymis. Like syphilitic orchitis, it is frequently bilateral. In the advanced stages caseous degeneration causes a breaking down of the tissues, and should the infection of suppuration be superadded the whole organ may become riddled with abscesses. Treatment. — The treatment must be carried out on the principles which govern the treatment of tuberculosis elsewhere. Residence at the seaside or a long sea-voyage is especially to be recommended. When the disease is confined to one testicle and has advanced to the destructive stage, the organ being riddled with sinuses, castration is advisable, care being taken to divide the vas deferens as high up as possible. Gouty orchitis is exceedingly rare, and closely resembles the syphilitic form. It is not always easy to trace its connection with the gouty diathesis. The enlargement is confined to the testicle itself, the epididymis remaining unaffected. Like other manifestations of gout, this form of orchitis is painful, and in some cases the inflammation is severe. Malignant Disease of the Testicle. — Carcinoma of the testicle appears as the encephaloid or soft variety. A peculiarity of cancer in this situation is that it attacks men comparatively young, the major- ity of cases being between twenty and forty. It is usually confined to one testicle, and appears as one or more small hard nodules in the body of the testis, the epididymis becoming involved later. At first the surface of the tumor is smooth and even, but as the growth increases and breaks through the tunica albuginea it becomes uneven, with hard and soft areas alternating. The progress of the disease is characterized by the horrible features which are inseparable from cancer. The growth is steady and may attain an enormous size ; large veins traverse its surface ; the skin becomes adherent, just as it does in cancer of the female breast ; it ulcerates, and a fungous mass breaks forth covered with unhealthy granulations, foul smelling, and throwing off sloughs of connective tissue and even parts of the gland itself This fungous mass is very vascular, bleeding on the slightest irritation, and sometimes threatening life by profuse hemorrhage. The epididymis has suffered early, the cord falls a victim later on, and the destroyer passes on to the glands and to distant organs till the life of the patient goes out in exhaustion. Sarcoma may occur at any age, not even the unborn infant being exempt. The most of the cases are below ten or between thirty and forty. Following a law of sarcoma, the round-celled variety is the most malignant, and sometimes it is an impossibility to distinguish it from soft cancer ; but practically it matters little, for both are terribly malignant, the same treatment is demanded, and, unfortunately, the 29 450 SURGICAL DIAGNOSIS AXD TREATMENT. resources of our art arc set at defiance by one as well as by the other. In the other forms of sarcoma, the spindle-celled and the t^iant- celled, cysts are frequently met with, and sometimes cartilaginous formations. Sir Astley Cooper called these cysts " hydrated testicles." They must be distinguished from hydrocele and hematocele, and gen- erally this can be done without difficulty, for the cystic testicle is heavier than a hydrocele and is opaque. Hematocele is more apt to cause confusion, but if a trocar be inserted the hematocele will be found to contain blood more or less altered, while the cystic growth produces little or no blood. Cartilaginous growths must always be looked upon with suspicion ; theoretically they are benign, clinically they are almost sure to be associated with sarcoma. The features that distinguish sarcomatous from other enlargements of the testicle, accord- ing to Jacobson, are — i. Continuously progressive solid enlargement without inflammation ; 2. Unequal resistance of the swelling at differ- ent parts ; 3. Entire absence of translucency ; 4. Tendency to become adherent; 5. Increasing aches or painfulness ; 6. Enlargement of the cord and, a fortiori, of the lumbar glands. Treatment. — No hope can be held out to a patient suffering either from carcinoma or sarcoma of the testicle, except by early removal of the gland. Even then the prospect of permanent cure is not bright. The operation, however, is attended with but slight danger, and, as it is almost sure to prolong life and lessen suffering, its performance should not be delayed. Operatio}i. — Castration is performed as follows : The parts having been shaved and disinfected, the skin is steadied by the thumb and fingers of the left hand, and an incision made from the external abdom- inal ring along the course of the cord and down to the lower end of the scrotum. This incision, however, is not advisable when the skin is adherent to the adjacent parts. An eliptical incision meeting above and below the adherent portion is the best under such circumstances. Layer by layer is divided ; all are freely movable until the tunica vagi- nalis is reached, when it will be found to be immovable. The first layer, then, which is immovable is the tunica vaginalis. This should be opened for diagnostic reasons, and if necessary to reduce the size of the tumor. The cord having been separated from surrounding tis- sues and the tumor shelled out by the finger, aided here and there by touches of the knife, moderate traction is made upon the cord, and it is then tied off This can be done in several ways: i. The cord is grasped with a clamp, divided below the instrument, and the vessels tied separately. This is the safest and best method. 2. The whole cord may be tied eii masse by a stout chromicized catgut or silk liga- ture, the ends cut off short and allowed to slip up into the canal. 3. A double ligature may be passed through the substance of the cord and the two halves tied separately (Jacobson). Some operators place a rubber drainage-tube in the inguinal canal in contact with the stump of the retracted cord, but this is unnecessary. The utmost care should be taken to ensure complete hemostasis before losing sight of the cord or closing the wound, for even the oozing of a small vessel may cause troublesome hemorrhage for days after the operation. In closing the THE GENITO-URINARY SYSTEM. 451 wound a blunt hook placed in each angle should be made to stretch the edges of the skin and prevent their turning inward by the action of the dartos. Benign Tumors. — These may be cystic or solid. Hydatid and dermoid cysts are difficult to diagnosticate except by removal and examination of their contained fluids. Cystic adenomata grow slowly, are free from pain, and rarely appear before puberty. The solid tumors are fibromata and enchondromata. While cysts present a nodular appearance, these solid growths are smooth. The testicle is hard and heavy% thus simulating the syphilitic testicle. Abnormalities of the Testicles. — The testicle sometimes fails to reach the scrotum, and remains at some point in the inguinal canal, in the abdominal cavity, or just outside the external abdominal ring. This abnormality is known as retained testicle. Its chief inconvenience con- sists in the liability of the organ to inflammator}' attacks. It sometimes, when complicated with hernia, prevents the wearing of a truss, and is probably a predisposing cause of malignant disease. Treatment. — Unless the retained organ gives trouble it is best to let it alone, no operation for placing it in its proper position havang so far proved satisfactory. When it is producing trouble and the other organ is normal, castration is the proper course. Absence of both testes is rare, but it is not very uncommon to find an individual who only possesses a single gland. Hydrocele is a term applied to any collection of fluid about the Fig. 194. — Hydrocele (Keen and White). testicle or spermatic cord, but, as a rule, this fluid is confined in the tunica vaginalis. It occurs at any age, and may vary in size from a barely perceptible enlargement of the scrotum to a tumor of enormous dimensions. Traumatism, violent muscular effort, and relaxation of the scrotum by residence in tropical climates have been assigned as causes. In the congenital form of the disease the peritoneal cavity commu- nicates with the tunica vaginalis, thus allowing the abdominal serum to trickle down along the cord to the testicles. The diagnosis of hydrocele is generally easy. The swelling is first observed at the lower end of the scrotum ; it is smooth, tense, fluctu- 452 SURGICAL DIAGNOSIS AND TREATMENT. ating, and increases slowly. It is free from pain and other inflamma- tory symptoms. All these symptoms are not sufficient to differentiate hydrocele from other enlargements in the scrotum, but there is one sign which is pathognomonic, and that is the translucency of the tumor. If the patient be examined in a darkened room and the scrotal swelling held between the surgeon's eye and a lighted candle, the tumor will allow the light to pass through it ; all other scrotal swellings are opaque. This test, however, is interfered with if the tunic is greatly thickened, as is sometimes the case, or if the serous fluid is mixed with blood. The aspirating needle should be employed in cases of doubt. Inexperienced examiners are liable to mistake hernia for hydrocele, and vice versa, and the writer has more than once been consulted because a truss for inguinal hernia could not be made to fit over a hydrocele. With ordinary care and a study of the symptoms this error need not occur. Except when strangulated a hernia has an impulse on coughing, and the swelling can be traced up to and into the inguinal canal. Both hernia and hydrocele may be present, but even then an impulse can be felt when the hernial portion of the swelling is grasped between the thumb and finger. Hydrocele of the cord is recognized by its sausage shape and by its being connected with the cord. Treatment. — Congenital hydrocele may be cured by a truss, which prevents the flow of serum from the abdominal cavity into the tunica vaginalis ; failing in this, the neck of the sac should be ligated. The treatment of other forms is palliative or radical. Palliative treatment consists in tapping the tunic as often as it becomes over-dis- tended. The radical operation aims to obliterate the sac by the injec- tion of iodin or carbolic acid or by incision. Tapping is thus performed : The position of the testicle having been ascertained, the skin and trocar disinfected, the left hand grasps the tumor so as to render the skin tense. The trocar is grasped by the thumb and finger of the right hand so as to form a guard which will prevent the instrument being thrust in too far, and is then by a quick movement made to perforate the scrotum. If the object is simply palliative, the trocar is withdrawn and the fluid allowed to escape through the cannula. In the radical operation the fluid is withdrawn, and then the cavity is injected with five or six drams of the undiluted tincture of iodin, which should be caused to permeate every part of the sac by shaking up the scrotum or gently kneading it. The opening made by the trocar is closed by iodoformized collodion. Instead of tincture of iodin, some surgeons use from five to ten drops of pure carbolic acid in sufficient water to keep it in a liquid state. It produces less irritation than iodin. For the first two days after injection the swelling may return to its former size and the parts become violently inflamed, but this soon subsides and a cure may be expected at the end of three or four weeks. Incision is an effectual method of dealing with hydrocele. It con- sists in laying open the tunica vaginalis for a distance of about an inch and a half and stitching the edges of the tunic to the skin. A drainage- tube is inserted or the cavity packed with iodoform gauze and allowed to heal by the open method. THE GENITO-URINARY SYSTEM. 453 Hematocele is a condition in which the tunica vaginahs is distended with blood. It sometimes occurs after tapping a hydrocele or it may follow a traumatism or inflammation of the tunic. The tumor is ovoid in shape, but broader at its most dependent part. It does not fluctuate, but is hard, opaque, and heavy. Difficulty may arise in distinguishing it from an old hydrocele with thickened walls, and from tumor of the testicle. In some cases this point can only be decided by exploration or incision. Traumatic hematocele is easily recognized by the rapidity with which the symptoms develop, a tumor of considerable size forming in a few minutes or a few hours at most. Treatment. — In acute traumatic cases the patient should lie in bed with the scrotum supported on pillows, while cold and moderate pres- sure are employed to check the extravasation of blood. Failing to get rid of the hematocele in this manner, and especially if the case is of long standing, the proper course is to lay the part open by an incision, turn out the clots and fibrinous deposits, examine the testicle, and remove it if diseased or disorganized, pack the cavity with iodoformized gauze, and allow it to heal by granulation. Inflammation of the spermatic cord very rarely occurs as a pri- mary affection, but as a sequel of gonorrheal or syphilitic orchitis it is not uncommon. The cord is hard, tender to the touch, and painful, especially when the weight of the testicle drags upon it. The consti- tutional symptoms are often well marked, but it is seldom that the dis- ease proceeds to suppuration. The treatment is that of other local inflammations, with attention to the specific disease which may be acting as a cause. Hydrocele of the Cord. — Two varieties are recognized — diffused and encysted, the latter being the more common. Diffused Hydrocele. — This variety arises as follows : In its descent to the scrotum the testicle carries with it a double layer of peritoneum, which goes to form the serous sac lining the inguinal canal : one layer is in contact with the spermatic cord and the tunica albuginea, the other with the inner surface of the cremaster muscle and the scrotum. Between these two layers, as they surround the testicle, is the space known as the tunica vaginalis. In normal development the space between the two layers becomes obliterated at the lower end of the inguinal canal, so that the two become blended into one as they invest the spermatic cord. Sometimes, however, this blending does not take place, and the layers remain separate in the inguinal canal. If serum accumulates in this space, it forms a tumor resembling a sausage and extending from the internal abdominal ring almost to the testicle. It is readily recognized by fluctuation and by its shape. When the patient stands up, the fluid, gravitating to the lower end of the canal, gives the tumor a pyriform appearance. The same effect can be produced by pressure downward along the course of the cord. The similarity of this tumor to omental hernia is likely to mislead the unwary, especially when it has an impulse on coughing, as is sometimes the case. Care should be taken to note the change in shape brought about by the position of the patient, the fluc- tuation at the lower end of the tumor, and its bulging when pressure is 4S4 SURGICAL DIAGNOSIS AND TREATMENT. made downward aloni:^ tlic course of the cord. It must also be remem- bered that both h\-drocele and omental hernia ma)' coexist. Trcatiiioit. — The tumor can be aspirated and injected with iodin as an ordinary h}'drocele. Encysted Hydrocele. — When the two layers of the covering of the cord are blended in several places, the intervening spaces remaining sejiarated, and when these spaces become distended with serum, the condition is known as encysted h)'drocele (Fig. 195). While the patient stands erect the symptoms resemble those of the diffuse form of hydrocele, but on assuming the recumbent posture the tumor disappears slowly. This distinguishes it from hernia, for the latter goes up quickly and has its peculiar gurgle. Treatment. — This form can usually be cured by wearing a truss. In infants simple puncture is often sufficient. Failing in this, a silk thread should be passed through the tumor, loosely knotted, and left to act as a seton for forty-eight hours. This operation should be carried out with aseptic care and the part covered with an aseptic dressing. A sufficient amount of inflammation is thus established to cause obliteration of the sac. Varicocele. — The term varicocele is applied to a dilated and tortuous condition of the veins of the spermatic cord. Two groups of veins exist in the cord — the anterior, accompanying the spermatic artery and forming the pampiniform plexus ; it is this group which is most commonly involved in varicocele. The posterior group attends the spermatic artery and surrounds the vas deferens. Occasionally this group also becomes varicose. Varicocele occurs almost universally on the left side, and for this clinical fact the following reasons have been assigned : I. The left vein as it enters the renal vein has no valve. 2. It is longer than the corresponding vein on the right side. 3. It enters the renal vein at a right angle to the current of the blood. 4. It passes behind the sigmoid flexure and is subject to occasional pressure. Symptoms. — No great skill is required for the diagnosis of varicocele. The scrotum contains a soft mass resembling a bunch of worms. There is usually no acute pain, but a dull aching is commonly present. The scrotum hangs down loosely and is of a purplish color, and the tortuosities of the veins can be seen through the skin. Perspiration on that side of the scrotum is usually present. The testicle is generally soft and sometimes atrophied. Like many other disorders of the sexual system, varicocele is apt to produce a form of melancholia, and many patients erroneously get the idea that they are impotent. Treatment. — Palliative treatment consists in wearing a suspensory bandage, and nearly every patient who consults a surgeon for varico- cele comes clothed in this regalia. For mild cases attended with no pain or inconvenience this is satisfactory, but when pain and constant aching are present, when the testicle is gradually wasting away or the Fig. 195. — Encysted hy drocele. INJURIES AND DISEASES OF THE HEAD. 455 patient's mental condition threatening to prove serious, something of a more radical nature is demanded. Two operations are in common use, either of which can be recommended. I shall mention first the operation of incision of the veins, with shortening of that side of the scrotum, as it is the most thorough and satisfactory when properly performed. In any operation upon the cord the vas deferens must be located and kept out of harm's way. It lies at the posterior and inner aspect of the cord, and is recognized by its tough, leathery feel. It has a per- sistent way of slipping out of the grasp of the thumb and finger. Operation. — The parts having been shaved and thoroughly disin- fected, an assistant locates the vas deferens and keeps it out of the way, while at the same time he makes tense the skin of the scrotum. The operator then makes an incision for about two inches over the most prominent part of the varicocele. The group of veins is exposed, but not separated from one another, and at the lower end of the incision an aneurysmal needle is passed beneath the group, carrying a short catgut ligature. This is securely tied and one end cut short. A ligature is applied in a similar manner at the upper angle, and one end cut short as before. The portion of the plexus lying between the ligatures is then removed by scissors. The two long ends of the ligatures are next tied together, thus shortening the cord and raising up that side of the scrotum. The incision in the skin is closed with a continuous catgut suture and a proper dressing applied. The second operation is that of Keyes. The vas deferens being kept well in the background, a needle armed with stout aseptic silk is passed through the scrotum between the vas and the group of veins, and left in position ; a second needle, threaded with the free end of the same thread, is entered beside the first needle, and, after passing through the skin and dartos, is carefully made to surround the veins and emerge beside the first needle at the opposite side of the scrotum. Both needles are now drawn through, thus placing a loop around the veins. The silk is securely tied in a single square knot and the ends cut short. The two layers of scrotal skin are now separated, and the knot slips within the dartos, where it becomes encapsulated. The small openings made by the needles can be sealed with iodoformized collodion : the patient should remain in bed one day and keep in-doors for four or five days longer. CHAPTER VIII. INJURIES AND DISEASES OF THE HEAD. I. CEREBRAL TOPOGRAPHY. Injuries of the scalp and of the bones of the cranium would have no special importance were it not for the danger of brain-complications, which danger is ever present in such traumatisms. A wound of the scalp heals as readily as a wound of the soft parts in any other portion 456 SURGICAL DIAGNOSIS AND TREATMENT. of the body, but unless the greatest care be taken in its treatment such a wound may become infected, and the infection may thence be carried to the brain or its membranes. A fracture of the skull, as far as the bone itself is concerned, is unimportant, for union readily takes place, and there is not so much thickening at the point of union as is usually found in repair of other bones. But fractures of the skull are exceed- ingly grave injuries, from the fact that the fragments almost invariably cause direct compression of the brain or produce hemorrhage, which is a source of danger no less grave. Before proceeding to the injuries of the head the brain itself must claim our attention. An organ so essential to the economy, so highly developed, so exquisitely delicate and sensitive, must of necessity be well protected. The skull is the strong casket which contains this precious jewel, and to this end it is admirably adapted. It is formed of strong bones, with additional strength where most exposed to violence, presenting a con- vex surface from which blows glance and missiles are deflected. Within the cranium cushions of cerebro-spinal fluid support the brain and break the force of shocks and jars to which it would otherwise be exposed. The strong and unyielding skull, however, is, under certain condi- tions, a source of danger to the brain. When inflammation attacks the organ or its membranes, when pus accumulates or blood is extrav- asated, there is no room for expansion ; brain-pressure soon follows, showing its presence by paralysis or by other manifestations of func- tions impaired or entirely destroyed. Dangers from this source are not only immediate, but remote, assuming at more or less distant periods the form of epilepsy or insanity. Although the functions of the various regions of the brain are still imperfectly understood, a wonderful amount of light has been thrown upon this subject in recent years. For our knowledge in this interest- ing field of study we are indebted to Broca in France, Fritsch, Goltz, and Hitzig in Germany, and Ferrier and Horsley in England. Their investigations have demonstrated the fact that different parts of the brain preside over different motions of the body. The functions of certain areas are pretty definitely understood, while other parts are still a terra incognita. There are five areas whose functions have been demonstrated ; they are — i. The sensori-motor area; 2. The area which presides over speech; 3. The area of vision; 4. The area of hearing; 5. The area of sensations of smell and taste. I. The Sensori-motor Area. — To comprehend the limits of these areas let us examine the outer surface of the left hemisphere of the brain (Fig. 196). The cerebrum is divided into two hemispheres, the right and the left. The gray covering or cortex of each hemisphere presents three surfaces — the lateral, the median, and the basal. The most interesting to surgeons is the lateral surface, in the study of which we recognize certain fissures, lobes, and convolutions. It has four lobes — the frontal, parietal, occipital, and temporal. Each lobe is furrowed by certain fissures or sulci, and between these lie the convolutions or gyri. The frontal lobe (F) contains two sulci, the superior and inferior (/i and f). It also contains the following convolutions : the superior. INJURIES AND DISEASES OF THE HEAD. 457 median, and inferior frontal {F^, F^, F^), and the ascending frontal or anterior central convolutions (A). The Parietal Lobe. — Between the frontal and the parietal lobe is the fissure of Rolando (<:-). This lobe contains the posterior central con- volution {B) and the superior and inferior parietal lobules {P^, P.^. The inferior parietal lobule is subdivided into the supramarginal convolution at the posterior limit of the fissure of Sylvius, and the angular gyrus bending round the posterior limit of the temporo-sphenoidal fissure {P^}. The temporal lobe lies between the fissure of Sylvius and the cere- bellum. It contains the first and second temporal fissures and the first, Fig. 196.— Outer surface of the left hemisphere (Ecker) : A, anterior central or ascending frontal convolution ; B, posterior central or ascending parietal convolution ; c, sulcus centralis or fissure of Rolando ; cw, termination of the calloso-marginal fissure : F, frontal lobe ; F\, superior, F-i, middle, and Fz. inferior frontal convolutions ; /i, superior, and f-i, inferior frontal sulcus ;/3, sulcus praecentralis ; ip, sulcus intraparietalis ; O, occipital lobe ; 0\, first, 02, second, O3, third occipital convolutions; t^i, sulcus occipitalis transversus ; (12, sulcus occipitalis longi- tudinalis inferior; P, parietal lobe; po, parieto-occipital fissure; P\, superior parietal or pos- tero-parietal lobule; P-i, inferior parietal lobule— viz.

At first thought one might expect to find that the boundaries of these areas would follow the lines of the lobes and convolutions, but such is not the case. It is interesting to note that the relative positions of the motor centers correspond with the relative positions of the parts over which they preside. Instead of inscribing the names of the parts controlled, I have had drawn upon the brain itself the figure of the body (see Fig. 197), showing at a glance the whole field of cerebral localization and adding new interest to this absorbing study. It looks as if the Almighty had traced his own image upon the masterpiece of his handiwork, and recorded the crowning triumph of creation in a language which we are just beginning to learn, and in characters which we hope soon to decipher. The first landmark to which we must direct our attention is the 458 SURGICAL DIAGNOSIS AND TREATMENT. fissure of Rolando (r). It may be compared to a ravine, one bank of which is formed by the anterior central convolution, the other by the posterior central convolution. In the cortex of this area and in the adjacent cortex in front and behind is located the sensori-motor area. The left hemisphere of the brain presides over the right side of the body, and the right hemisphere over the left side. Roughly speaking, the upper one-third of the sensori-motor area controls motions of the lower extremity of the opposite side, the middle third controls the upper extremity of the opposite side, and the lower third presides over the movements of the face (see Fig. 197). To be more precise : let us first examine the upper third or the area of the leg. The fissure has in front of it the anterior central convolu- FlG. 197. — Cerebral localization. tion, and posterior to it is the posterior central convolution. Proceed- ing from before backward, we find that the anterior central convolution controls motions of the thigh, and the posterior central convolution con- trols movements of the leg, foot, and toes. In front of the thigh district is supposed to be the region which controls movements of the trunk (Fig. 197). In the middle third of the fissure of Rolando and in the convolutions on each side of it is the arm center. Well forward in the posterior part of the second frontal convolution is the area which governs the movements of the head and eyes. Proceeding backward, we find the area for the shoulder and elbow in the anterior central convolution, and, crossing over the fissure, we come upon the district of the wrist, fingers, and thumb in the posterior central convolution. In the lower third of the fissure and the anterior and posterior cen- tral convolutions is the area which governs the face, tongue, pharynx, and larjaix. The upper and anterior portion of this area controls the eyebrows and cheeks, the lower and forward part the tongue and INJURIES AND DISEASES OF THE HEAD. 459 larynx, and the posterior part the mouth, pharynx, and platysma myoides. When we say that a given area controls a certain motion or a certain part of a Hmb, we must not assume that the area in question ends abruptly. This is in accordance with Nature's laws. The colors of the rainbow are not sharply defined, but beautifully blended. The light of day does not suddenly cease and the darkness of night begin, but the atmosphere catches the departing rays, and, refracting them to the earth, changes day into night through the mellow light of the gloaming. So it is with the brain : each motion or each part of a limb has a special point which controls it in a pronounced manner, but shading off from this point the neighboring cortex controls it also, the power lessening as we go away from the special focus. If, for instance, the portion of the brain which controls the motion of the thumb be removed, paralysis of the digit will not follow, for the thumb is repre- sented, although in a less degree, in the neighboring areas. It is interesting to note that the coarser movements, such as motion of the head, the shoulders, the trunk, and the thighs, have their centers in the anterior portions of the motor area, and as we proceed backward the movements which are represented are of a more and more delicate character. Thus the delicate movements of the face, the lips, the fingers, and the toes have their centers in the posterior part of the motor area. Proceeding backward, the centers of sensation probably occupy the region next in order (Fig. 197), and lastly, the most delicate of all, the seat of vision. 2. The Area of Speech. — Speech has a wide representation and occupies four areas in four different locations — vdz. : {a) Motor spcccJi, or the movements required in the production of speech, is represented in the posterior part of the third frontal convo- lution, on the left side in right-handed persons and on the right side in those who are left-handed. Just behind the coronal suture and running parallel to it is the precentral or vertical sulcus (/g, Fig. 196). It is the anterior boundary of the motor area. It lies in front of the fissure of Rolando, and is separated from it by the width of the anterior cen- tral convolution. Around the lower end of this sulcus the anterior central convolution makes a bend, and lies in the hollow formed by the limbs of the fissure of Sylvius. This area is called the operculum, and in it is Broca's center for speech. The symptoms produced by disease in this area are loss of the use of language and the power of speech. The loss of power to convey our thoughts by writing is called agraphia. The center representing this power is not definitely settled, some cases going to show that it is in Broca's center, others that it is near the area of the hand and wrist. {B) The Auditory Speech-area. — In the first and second temporal convolutions is the area which receives the sounds of words and retains the memories of these sounds. Disease in this region causes the per- son to lose the memory of words, to be unable to recollect the names of the most familiar objects, and to fail to understand language when he hears it. {c) The Area of Visual Speech. — A person may be able to see the words of printed language, but may not understand them, and is 460 SURGICAL DIAGNOSIS AND TREATMENT. thereby unable to read. Such symptoms would indicate disease in the inferior parietal rei^non. 3. The Area of Vision. — 'rins centre is situated in the cuneus and the occipital lobe of the brain. Disease here causes blindness in half of both retinae, and to this condition the name hemianopsia has been applied. From the right half of each retina impressions are con- veyed to the left side of the brain, and from the left half of each retina to the right cerebral hemisphere. Disease of the visual area therefore causes blindness of the right or left half of each retina ac- cording as the left or right side of the brain is affected. 4. The area of hearing is located in the first and second temporal convolutions. Disease of this area, if confined to one side of the brain, does not produce deafness, for the reason that each ear has a connection with both hemispheres. If both sides of the brain are diseased, deaf- ness is complete. 5. Smell and taste are represented at the tip of the temporal lobe (Fig. 196), but the clinical value of changes in these senses is not very great. In the first place, both are easily blunted or modified from trifling causes, and, in the second place, each is represented on both sides of the brain. The surgeon, in order to deal with injuries and diseased conditions of the brain, must be able to locate the various areas on the outer sur- face of the skull. For finding the fissures certain rules have been laid down, which we shall now consider : 1 . The fissure of Bichat, which lies between the cerebrum and cere- bellum, is readily located by drawing a line from the external auditory meatus to the external occipital protuberance. This line, continued around the occiput to the opposite meatus, corresponds to the lateral sinus. 2. The fissure of Rolando is the most important of all the fissures from a surgical standpoint, for on each side of it lies the sensori-motor area. The upper limit of the fissure is thus located : Measure the dis- tance from the glabella to the external occipital protuberance ; at a point which represents 55.7 per cent, of this distance is the beginning of the fissure. For all practical purposes a point a half-inch behind the middle of this line is sufficiently accurate. The fissure runs downward and forward at an angle of 67° ; the next point, therefore, is to find that angle, and for this purpose several ex- pedients have been adopted. The simplest and readiest is that of Mr. Chiene of Edin- burgh. A square piece of paper (Fig. 198) is so folded as to bisect one of its an- gles, BAD. The result is an angle of 45°, BAG. The angle D A C is again o ^v . .u J r c bisected by folding the paper on the line A 198. — Chiene s method of fix- _^ ,-' ,9 i <- in ■~^^ position of Roiandic fissure. F, and the result IS an angle of 22^^". 1 he angle BAG (45°), plus the angle G A E (22^°), makes an angle of 67-^°, which is near enough for all practical purposes. The side A B is then applied to the middle line of the scalp. INJURIES AND DISEASES OF THE HEAD. 461 SO that the point A is half an inch posterior to the middle of the line between the glabella and the external occipital protuberance. The line A E will represent the position of the fissure of Rolando. I .-^1 . . .61 , I .s| . I .■»! . , »| . I ?| . ^ .«! . , o| \^sM.,.\^...\y..V..A Fig. 199. — Horsley's cyrtometer (as modified by Dr. Morris J. Lewis). The length of the fissure is 3f inches. The upper third of this line will indicate the position of the leg area, the middle the arm area, and the lower the face. Another method of finding the angle of the fissure of Rolando is that recommended by Horsley. He has devised a cyrtometer consisting of two strips of metal or parchment-paper, as represented in Fig. 199, the long arm of which is 14 inches in length ; to this a lat- eral arm is attached at an angle of 67 '^. The long arm is graduated each way from a zero point half an inch in front of the short arm. The long arm is applied to the middle line in such a way that the glabella and the external occipital protuberance will each mark the same distance from the zero point. The short arm, being half an inch behind this point, will correspond with the fissure of Rolando, and the figures 3I on the scale will represent the length of the fissure. 3. The fissure of Sylvius is found as fol- lows : First draw a base line from the lower margin of the orbit to the auditory meatus ; draw a line parallel to this from the external angular process running backward one inch and a quarter and then upward one quarter of an inch. This point represents the be- ginning of the fissure of Sylvius. From it to the parietal eminence draw another line, and it will represent the course of the fis- sure, which is four inches in length. The anterior limb of the fissure is two inches behind the external angular process. An- other method of finding the fissure of Sylvius is as follows : From the external angular process (Fig. 200), E A P, to the external occipital Fig. 200. — Head, skull, and cerebral fissures (adapted from Marshall by Hare) : B corre- sponds to Broca's convolution ; EAP, external angular process ; FR, fissure of Rolando ; IF, in- ferior frontal sulcus ; IPF, intra- parietal sulcus ; MMA, middle meningeal artery ; OPr, occipital protuberance ; PE, parietal emi- nence ; POF, parieto-occipital fissure ; SF, Sylvian fissure ; A, its ascending limb ; TS, tip of temporo-sphenoidal lobe. The pterion (to the left of B) is the region where three sutures meet — viz. those bounding the great wing of the sphenoid where it joins the frontal, parietal, and temporal bones. 462 SURGICAL DIAGNOSIS AND TREATMENT. protuberance draw a line passing about half an inch above the auditory meatus. At a point upon this line one and one-eighth inches from the external angular process draw another line to the parietal eminence, P E ; this corresponds with the main branch of the fissure of Sylvius. The anterior ascending branch follows the squamoso-sphenoidal suture for its entire length and ascends about half an inch higher. II. INJURIES AND DISEASES OF THE SCALP. Contusions. — Bruises of the scalp are frequently met with, and claim special attention owing to one peculiarity — namely, the resem- blance of their symptoms to those of fracture of the skull. When a blow is received upon the head, swelling begins almost at once, and is due to extravasated blood and effused serum. The swelling is soft in the center, and is sharply defined at the circumference, instead of blend- ing with the surrouncling parts. These features give the appearance of a depressed fracture, and should there chance to be a small ruptured vessel in the center, pulsation of the brain is very closely simulated. The diagnosis between this and depressed fracture is made by press- ing firmly with the finger at the bottom of the depressed area. If it is a simple contusion, the surface can be still further indented and the smooth bone can be felt beneath. The surrounding swelling " pits " on pressure. This i.snot the case in fracture. When the bone is depressed there is also compression of the brain, as a rule, while this is absent in contusion, unless there is at the same time rupture of a vessel within the skull which is forming a clot of blood on the cerebral surface. Compression caused in the last-mentioned manner does not come on immediately after the receipt of the injury. The treatment of contusions consists in moderate pressure and the application of lead-and-opium lotion. For the relief of swelling and pain massage acts most satisfactorily. If a slight abrasion of the skin is made by the blow, suppuration may follow and an abscess form beneath the scalp, which must be promptly evacuated. The most important part of the treatment consists in guarding against complications ; for symptoms of inflammation of the brain may set in or inflammation may extend over the whole scalp, or a traumatic aneur>'sm may form beneath the scalp, any of which must be met with its appropriate treatment. Cephalhematoma, or caput succedaneum, is readily recognized as a soft tumor seen on new-born infants, and generally at the parieto- occipital region. It is the effect of prolonged pressure during labor. In most cases no treatment is required, the swelling disappearing at the end of two or three days. Should it prove unusually obstinate, as I have seen in two cases, the fluid may be aspirated and pressure applied. Wounds of the scalp would not need special mention were it not that they are liable to be followed by serious consequences which do not threaten wounds of other parts. Patients suffering from scalp-wounds are usually taken to the nearest drug-store, where an artistic dressing of strips of sticking plaster is arranged in a stellate or a tessellated pattern. Of all dressings, probably sticking plaster is the worst ; it is INJURIES AND DISEASES OF THE HEAD. 463 not aseptic, and it confines the pus which is sure to form in a wound so treated. From the scalp the pyogenic germs may find their way along the vessels which perforate the skull, and thus reach the brain itself. In dressing a wound of the scalp the greatest care should be taken to cleanse the injured part. The hair should be shaved for some dis- tance around the incision ; all impurities should be got rid of by wash- ing with sterilized water and then with sublimate solution. In lacerated wounds an attempt should be made to save even flaps of skin which are only attached by narrow pedicles, for the blood-supply of the scalp is so abundant that the vitality of these pieces is likely to be maintained. The edges should be brought together and held by stitches of catgut or silkworm gut, and an antiseptic dressing applied. For small wounds here or elsewhere iodoformized collodion forms a simple and easily applied dressing. Tumors of the Scalp. — The most common by far of scalp-tumors are sebaceous timiors, or iveiis (Fig. 201). They are readily recognized Fig. 201. — Sebaceous cysts of scalp (from a photograph in the collection of Dr. Lincoln). by their rounded, even shape and their being painless. They cause inconvenience simply by their awkward position, the patients complain- ing that the tumors annoy them when combing their hair or interfere with the headgear. They are usually single, but frequently multiple, and their growth is slow. The treatment is extirpation. After disinfecting the scalp the hair can be parted over the tumor and an incision made through the skin down to the cyst, which can generally be dissected out without evac- uating the contents. Or the whole tumor maybe transfixed with a scalpel and the cyst-wall grasped with forceps and pulled out. In any case the cyst-wall must be totally removed. The skin is brought together with sutures and a dressing applied. Fatty tumors are sometimes seen on the scalp, and they may be confounded with wens. They are, however, flatter and more deeply seated. An error in diagnosis is of no consequence, as the treatment of both is extirpation. 464 SURGICAL DIAGNOSIS AND TREATMENT. Horns and warts arc easily diagnosed. Horns should be removed by an incision including their base. Warts, if showing a tendency to rapid growth, are probably malignant, and should be extirpated. Pneumatocele, or a tumor containing air, has been found on the scalp in ioca.ses reported by Treves. The tumor is recognized by its being painless, smooth, elastic, and tympanitic. It is produced by erosion of the osseous tissue, allowing escape of air from the mastoid cells into the subcutaneous tissue. The treatment is pressure after evacuation of the air by a hypoder- mic needle. III. INJURIES OF THE SKULL. Contusions. — In other parts of the body a contusion of bone is liable to be followed by osteo-myelitis, and such is the case in bones of the skull ; but the mischief does not end here, for a chain of symptoms may follow such an injury, showing that the inflammatory process has spread from the bone to deeper structures. The blow which causes contusion of bone may produce hemorrhage between the pericranium and the skull. The effusion of blood and the inflammation which fol- low strip the periosteum from the bone and necrosis is the result ; or the blow may crush the cancellous tissue or rupture the veins of the diploe, or the vessels which run between the dura mater and the inner surface of the skull may be ruptured, and hemorrhage occur in that situation. The effects of a contusion of the skull may be summed up as follows : 1. Osteo-myelitis with separation of the pericranium. The symp- toms here are local pain and tenderness, inflammation, and perhaps the formation of an abscess. There is dull headache, but the constitutional symptoms are slight. The osteitis may be acute or may continue for years. A ver>' characteristic symptom of osteo-myelitis of the skull is the so-called "puffy tumor" of Pott. It is a flattened, circumscribed swelling over a spot w^hich is very tender on pressure. 2. The inflammation may extend to the dura mater. If blood has been poured out at the time of the injury, so as to separate the dura mater from the bone, the condition is thereby rendered more serious. The symptoms are still local. Inflammator>' products or a collection of pus may produce pressure-symptoms, but, as a rule, it is only when the third step is reached that these signs appear. 3. The inflammation extends to the arachnoid. Up to this point the inflamed area is localized, but now it extends over the surface of the membrane. From this membrane the extension to the pia mater and the brain itself is unimpeded. The symptoms change accordingly. The patient complains of malaise, headache, stiffness of the muscles of the neck, giddiness, chilliness, nausea, and vomiting. The temperature rises, and the senses of sight and hearing become abnormally acute. The location of the disease and its gradual advance can, in some cases, be followed by noting the effects upon the motor areas. Thus a loss of motion of the arm, followed by a similar loss in the leg, would indi- cate a spread of the inflammation upward along the sensori-motor area, and would also be an indication to trephine the skull over the part of the brain suffering pressure. If the disease advances, stupor, drowsi- INJURIES AND DISEASES OF THE HEAD. 465 ness, paralysis, and coma supervene, and the patient dies. After a blow upon the head we should watch carefully for cerebral symptoms, not feeling that the patient is safe until three weeks shall have passed with- out appearance of this complication. The second week is probably the most critical period. Treatment. — The smallest breach of skin upon the head should be dressed with great care, lest septic germs should gain an entrance to the contused bone and its coverings. The treatment must aim at pre- venting osteo-myelitis, meningitis, and inflammation of the brain itself. Perfect quiet should be maintained and the simplest diet enjoined. The bowels should be kept freely open by calomel or other purgatives. Cold applications to the head are required when there is the slightest indica- tion that the inflammation is taking a direction inward. Sedatives are necessary to relieve headache, and for this purpose the bromids are the best. When symptoms of pressure appear in the form of localized paralysis, such as of the arm, leg, or face, the part of the motor area of the brain indicated should be exposed by a large trephine opening with the view of getting rid of pus. Fractures of the Skull. — As far as the bones themselves are concerned, there is nothing remarkable about fractures of the skull. Union takes place as readily here as in other parts of the bony frame- work, and, as a rule, the repair is such as to leave little if any thicken- ing or deformity. The traumatism, however, which is severe enough to break the skull is almost sure to injure the brain, or the displaced fragments may be driven in upon the brain and its meninges, leading to the most serious consequences. Fractures of the skull are divided into those of the vault and those of the base. Fractures of the Vault. — If a force applied to a limited area of the skull is sufficient to make the bone yield, the effect will be {a) a fissure or crack in the skull, and it may extend for a considerable distance from the point to which the force has been applied. It is not uncom- mon to find a fissure which has run across sutures from one bone to another or has even extended so as to involve the base itself. (/;) The bone may be comminuted at the point of contact, (r) The fracture may be opposite to the point of contact, the so-called fracture by contrc- coup or counter-stroke, {d^ To the above I shall add a fourth class, in which the force may cause fracture at a part of the skull which is dis- tant from the point of contact, but not opposite to it. This is well seen in Fig. 202. The wounds of entrance and exit of a bullet are seen at opposite sides of the calvarium, while between them is a fissure extending nearly the whole length of the vault from the frontal to the occipital bones. Symptoms. — In examining the skull for fracture pass the fingers gently over the vault to ascertain the existence of any depression or sharp edges of bone. In many cases the fracture is compound, and the examination is made at the bottom of the scalp-wound. The wound itself should be carefully examined for splinters of bone or portions of brain-tissue. The finger, carefully disinfected, can now explore the wound, searching for depressions, fragments, or fissures. Next the edges of the wound are held apart, so that the tissues may 466 SURGICAL DIAGNOSIS AND TREATMENT. be seen. The fractured edge of bone has a dark-red color. A fissure may in some cases be detected by its holding in its grasp one or more hairs. A very old and infallible sign of fracture is the nature of the clot which is found in the wound : if there is no fracture, this clot can be wiped away; in the case of fracture no amount of washing or wiping can dispose of the clot. Simple fracture must be determined by the depression which is felt through the scalp. Care must be taken to distinguish this depression from the effusion of blood which takes place after a bruise of the scalp, the diagnostic importance of which has already been dwelt upon. Another symptom which can sometimes be elicited is the " cracked- pot " sound heard on auscultatory percussion. In some cases it is so distinct as to be heard without the aid of a stethoscope, and even by Fig. 202. — Fracture of the vault (from a photograph in the collection of Dr. C. H. Hunter). the bystanders. Rarely, it happens that the dura mater is wounded, and cerebro-spinal fluid escapes through the fractured skull and forms a translucent tumor beneath the skin. This tumor is recognized by its becoming tense with such movements as sneezing or coughing, and is positive proof of fracture. The outer table of bone may alone be broken. In such a case the depression is but slight and the cerebral symptoms are not marked. The inner table may also be broken alone. The symptoms are not sufficient for a positive diagnosis, and the fracture can only be suspected when, after a force applied to the head, evidence of cerebral inflamma- tion and pressure supervene. Treatment. — The question of treatment must be influenced by the amount of injury which the brain has suffered. The bone is of minor importance. INJURIES AND DISEASES OF THE HEAD. 467 In simple fracture, without evidence of compression of the brain, or if compression is passing off, perfect quiet and good nursing constitute all the treatment required. The patient should be kept in a darkened room, the diet should be light, the bowels should be freely moved by a dose of calomel. The head should be shaved, ice-bags applied, and the patient kept in bed for at least three weeks. When there is marked depression it is evident that the brain has been injured, and, although there may be no immediate evidence of compression or other injury to the brain, the proper course is to trephine with the view of preventing these complications. A depression of the skull is a perpetual source of danger, for if there be no immediate effects there may be developed at even a remote period insanity or epilepsy. In compound fracture of the vault the wound requires most care- ful attention. The whole scalp should be shaved, instead of a small portion around the wound, as is too generally the custom. After washing and disinfecting with corrosive-sublimate solution (i : 2000), and having arrested all hemorrhage and dried the parts, the surgeon next directs his attention to the condition of the bone. If the fracture is a simple fissure without depression, and no hairs or other foreign substances arr: caught in the fissure, the wound may be closed with catgut sutures and a copious dressing applied. If the fissure holds in its grasp dirt, hairs, or any other foreign material, the edges of the fissure should be chiselled away, removing the outer table of bone and leaving a V-shaped groove. Rubber drainage-tubes or strands of cat- gut should be placed in position and the wound closed and dressed. When there is depression the bone must be elevated to its proper level and loose pieces removed. It is true that the brain can endure a con- siderable degree of pressure, and that many patients recover in whose brains foreign bodies have existed for years, but the danger is always great. In skilful hands the operation of trephining is not of itself dan- gerous, but it should be resorted to as a preventive measure, and not as a last resort when the patient is dying of brain-disease. It may be sufficient to raise the bone by using an elevator, care being taken to bring the displaced portion up to its former level. When the bones are locked together, as is frequently the case, it is necessary to remove a portion of bone with the trephine. The pericranium, if healthy and uninjured, should be carefully preserved, and under favorable circum- stances the button of bone removed by the trephine may be replaced. After dealing with the fracture the wound is closed and dressed in the ordinary manner. Punctured wounds of the brain always demand the use of the trephine. Fractures of the Base of the Skull. — Fractures of the base may occur in one of the following ways : {a) A fissure of the vault may run downward and involve the base. It is convenient to divide fractures of the base according as they involve the anterior, the middle, or the posterior fossa. Fractures extending from the vault are apt to run into the middle fossa and through the petrous portion of the temporal bone. {p) The fracture may be caused by indirect violence, as when a person falls from a height, landing in a sitting posture, and communicating the force through the spinal column to the base of the skull, {c) The 468 SURGICAL DIAGXOSIS AND TREATMENT. lower jaw may be driven backward with such force as to fracture the base, {(i) Punctiu'ed fractures can occur through the cavities of the orbit, the mouth, and the nose. Syniptojiis. — There is one leading symptom which is proof of frac- ture of the base, and that is escape of blood and cerebro-spinal fluid from the ear. This sign, however, only exists when the fracture is in the middle fossa and involves the petrous portion of the temporal bone. And not even then must it follow that blood and fluid escape, for the membrana tympani must first be ruptured. Care must also be taken to distinguish between this kind of hemorrhage and bleeding from an ordinary wound in the ear. If it be a simple wound, the hemorrhage will soon cease ; if serum escapes, it is only the serous oozing which is common in every wound. When there is fracture the bleeding and escape of cerebro-spinal fluid arc very characteristic. The hemorrhage continues for a long time, and it may be both mixed with, and followed by, the watery dis- charge. This watery fluid escapes more profusely when the patient increases the intra-cranial tension by forced expiration, coughing, sneezing, or blowing the nose, and the flow is also influenced by the position of the body. The fluid should be collected and examined chemically. It contains chlorids in large amount, a trace of albumin, and sometimes sugar. There are other positions in which hemorrhage can be taken as an indication of fracture of the base — viz. the nose, the pharynx, beneath the deep muscles of the occiput, and the tip of the mastoid process. In any of these positions the bleeding is characterized by its long con- tinuance, lasting from twenty-four to forty-eight hours. When there is fracture of the orbital plate of the frontal bone, blood will appear at the end of one or two days as an ecchymotic swelling beneath the con- junctiva of the eyeball and, later, in the lids. An ordinary " black eye " produces ecchymosis of the eyelid first. Hemorrhage at the tip of the mastoid process, spreading upward and backward with a cres- centic margin, is an indication of fracture of the posterior fossa — a dangerous fracture. Escape of brain-matter is always proof of fracture. It is usually found in the nose or pharynx. Paralysis of the cranial nerves is an evidence of fracture of the base. Deafness and facial paralysis frequently go together, and afford evidence of fracture of the petrous portion of the temporal bone. Optic neuritis is evidence of fracture of the posterior fossa (Battle). In many cases the diagnosis of fracture of the base can only be suspected. If a fracture of the vault is extensive and takes a direction downward, we may infer that it reaches the base. A piece of wood entering the orbit must fracture the skull if it pierces the tissues to a greater depth than the orbital cavity extends, and an umbrella rib entering the floor of the mouth must perforate the brain unless the wound is very shallow. The term compound fracture has a wider significance here than in other parts of the body. A fracture of the base may communicate w'ith the external air through the ear or the nose or the mastoid cells, and is on that account compound, although deep within the cranium. It is important to keep this in mind in considering treatment. INJURIES AND DISEASES OF THE HEAD. 469 Treatment. — It is seldom that retentive apparatus is required to steady the fractured bones. When the traumatism is so great as to render this necessary, the head should be shaved, covered with a thin layer of absorbent cotton, and enclosed in a plaster-of-Paris cast. In the majority of cases treatment will consist in keeping the patient perfectly quiet and preventing sepsis in the injured part. The portals of entrance for septic germs are the ear, the nose, the eye, and the mouth. The ear must be thoroughly cleansed from blood, dirt, and wax, irrigated with warm corrosive-sublimate solution, packed with iodoform gauze, and covered with sublimate dressing. The mouth is kept as nearly disinfected as may be by the frequent use of antiseptic washes, such as boracic acid or a solution of Seiler'5 antiseptic tablets. The nose is thoroughly cleansed by peroxid of hydrogen and douches of boracic acid, and packed with sublimate gauze or borated cotton. The orbit requires particular attention when the fracture has occurred by that route. Drainage is the first consideration, and, if this cannot be otherwise secured, the roof of the orbit should be sufficiently cut away by gouge or chisel to giv^e free exit to pus and other products ; a drainage-tube can be placed in the wound, and after thorough disin- fection an antiseptic dressing can be applied. The middle fossa is best drained by a trephine opening above and behind the auditory meatus. The anterior fossa is reached through the nose by breaking through the cribriform plate of the ethmoid bone and inserting a drainage-tube. IV. INJURIES OF THE BRAIN AND ITS MEMBRANES. Concussion. — In the writings of the older authors the term con- cussion was used to imply a suspension or sudden arrest of the func- tions of the brain, the result of a force transmitted through the cerebro-spinal fluid to more or less distant portions of the brain, mainly the fourth ventricle. Authorities of to-day are pretty well agreed that the condition known as concussion is the result of actual injury to the brain, a laceration of its substance, the result of force applied directly or indirectly. Concussion and laceration may be used almost as synonymous terms. In this connection the experiments of Felizet are interesting. He filled a skull with paraffin and let it fall from a height which was not sufficient to fracture the skull. On exam- ination it was found that the bone was unbroken, but at the point of contact the paraffin was flattened, proving that when the force was applied the bone was driv^en in, and then by its resiliency bounded back to its place. No doubt the same resiliency exists in the living skull ; the bone rebounds, but the brain is bruised or lacerated and a small amount of hemorrhage takes place. In post-mortem examina- tion of cases of concussion it is common to find extravasation of blood into the meshes of the pia mater and beneath the arachnoid. Accord- ing to Duret, these are due to the waves communicated to the sub- arachnoid fluid, the force of which may have its greatest intensity opposite the point at which the blow is received. Symptoms. — In mild cases the injured person turns pale, becomes giddy, loses his balance, and falls. He may lie unconscious or semi- conscious, and after a time get up of his own accord or with slight 470 SURGICAL DIAGNOSIS AND TREATMENT. assistance. His mind is confused and he suffers from nausea, and per- haps vomits. In severe cases the symptoms are much more serious. The person falls suddenly, and lies perfectly still, totally unconscious or capable of being only partially roused. The heart is weak and the pulse fluttering. The pupils generally respond to light, but they may be unevenly contracted. Vomiting is the first indication of returning consciousness. After the patient has regained consciousness he suffers from headache, vertigo, and lassitude, and this may continue for several weeks. In the worst cases the injury to the brain is so great that the unconsciousness deepens into coma, or the symptoms of meningitis, cerebritis, or abscess are developed. Remote consequences of such injuries are epilepsy and insanity. Trcatiiicjit. — The treatment is the same as for contusions of the skull — perfect quiet and the closest watchfulness for brain-compli- cations. Among the laity it is a common practice to give alcoholic stimulants ; this is to be condemned, as their effects upon the brain may prove serious. Aromatic spirit of ammonia is free from this objection, and should headache prove troublesome a dose of bromid of potassium is proper. Every case of concussion should be looked upon as a serious injury, and no amount of remonstrance on the part of the patient should influence you in relaxing the rigidity of your management. Compression of the Brain. — An organ so delicate as the brain is intolerant of pressure, and refuses to perform its functions when en- croached upon by foreign bodies. The causes of compression are — hemorrhage above or below the dura mater or in the center of the brain, collections of pus, hyperemia, depressed fractures, and tumors. The time at which evidences of compression appear varies with the nature of the compression. Rapid extravasation of blood produces immediate compression ; inflammation does not produce it until the hyperemia or the inflammatory products have had time to develop ; tumors do not cause compression until an advanced stage of their growth, except when they are attended with hemorrhage ; in meningitis or osteo-myelitis of the skull this symptom does not appear until the second week, while an abscess in the cerebral substance may not reveal its presence until weeks or months after the accident which caused it. Symptoms. — The symptoms of compression are in many respects entirely different from those of concussion, and yet there are cases in which the diagnosis is difficult, as one condition runs into the other. There are degrees of compression too, for in one case the whole brain may suffer, in another the pressure may be local. Sudden compression may begin with convulsions. Total Compression. — The patient is completely unconscious and lies in a state of coma. One leading symptom is very pronounced, and can be heard the moment you enter the patient's room — stertorous breath- ing. If you watch the cheeks, you will see that they expand, and the lips are passively blown outward at each expiration. This is because they are paralyzed. In concussion we saw that the patient could be roused to semi-consciousness : not so in compression, for voluntary and reflex movements are in abeyance. The skin is cold, and usually INJURIES A.\D DISEASES OF THE HEAD. 47 1 it is covered with perspiration. The pulse is slow and strong. The pupils are fixed, generally dilated, and do not respond to light. The bladder has lost its power to contract, and becomes over-distended ; the feces are passed involuntarily. When the cause of compression acts slowly the following sequence of symptoms may be observed : The patient becomes restless and irri- table, and complains of nausea and other digestive disturbances ; there is severe headache ; the pupils are contracted ; the face is flushed ; the pulse is full and rapid, and the beating of the carotids is apparent to the eye. Impairment of speech, vomiting, and sometimes convulsions precede the period of stupor, which lasts as long as compression ex- ists. A rise in temperature is a symptom of great importance, and has a prognostic as well as a diagnostic value. It comes on early and is persistent. A subnormal followed by a high temperature demands a bad prognosis. Local Couiprcssio)i. — The patient does not lose consciousness, and the symptoms will depend upon the part of the brain which suffers compression. The anterior lobes show the least response, and it is not uncommon to find a considerable area of cerebral tissue destroyed without having shown symptoms during life. When the anterior por- tion of the brain is compressed no paralysis is produced, unless the posterior part of the inferior left frontal convolution becomes involved, in which case there is motor aphasia. Pressure in the motor area will be recognized by paralysis of the limbs or impairment of the movements over which the several districts preside, as follows : Paralysis of the lower limb indicates the upper third of the fissure of Rolando on the opposite side and the corresponding parts of the ascending frontal and ascending parietal convolutions (Fig. 197). Paralysis of the upper extremity indicates pressure upon the middle third of the Rolandic fissure and the corresponding parts of the con- volutions. Motor aphasia indicates pressure upon Broca's area in front of the lower third of the fissure of Rolando. Mind-blindness may be caused by pressure of the angular gyrus, as shown by a case of Macewen's in which a spiculum of bone from the inner table was driven in upon the anterior portion of the convolution. Word-blindness (apraxia) would point to the temporo-sphenoidal lobe ; hemianopsia, to the cuneus and its neighborhood. Pressure upon the pons Varolii or the medulla oblongata speedily endangers life by destroying the nerve-centers themselves or arresting the nerve-currents as they pass from the skull. In the diagnosis of compression of the brain the following must be excluded : alcoholic intoxication, opium-poisoning, apoplexy, and uremia. A drunken person, unless carrying a very heavy "jag," is not unconscious ; he probably has the appearance of habitual indulgence and the smell of alcohol taints his breath. Doubt may arise, however, from various sources : the drunken man may have fallen and caused an injury to his head, which injury may divert the attention of the examiner from the real condition. On the other hand, an injured person is almost sure to have stimulants poured down his throat by those who come to his rescue. The pupils of a drunken man are usually contracted, but they dilate w^hen he is aroused. The temperature is subnormal. The 472 SURGICAL DIAGNOSIS AND TREATMENT. effects of alcohol pass oft" in a few hours, when all doubt is removed if not before. Opium-poisoning is attended with the drowsiness and the deep sleep which characterize the effects of opiates ; the pupil is contracted to a pin-point and remains so, and there are no evidences of an injury to the head. Apopelxy is due in nearly all cases to hemorrhage of the lenticulo- striate artery, which Charcot has designated " the artery of cerebral hemorrhage." In this lesion unconsciousness comes on immediately or after a very short interval ; the breathing is stertorous, unconsciousness is complete, and there is cither hemiplegia or total paralysis. Uremia is recognized by a history of albuminuria, edema of the legs, and the absence of paralysis and stertorous breathing. Treatment. — Compression is only a symptom, and its treatment must depend upon the lesion which is acting as the cause. Intra-cranial Hemorrhage. — Hemorrhage within the skull, as a rule, arises from one of three arteries: i. The lenticulo-striate causes the hemorrhage of apoplexy, and comes under the consideration of the physician. 2. The middle meningeal produces those cases in which the bleeding is outside the dura mater. 3. The middle cerebral gives rise to hemorrhage beneath the dura mater — subdural hemorrhage. Other sources of intra-cranial hemorrhage are the sinuses, the small vessels of the membranes, and, in exceptional cases, the internal carotid artery. The cases of cerebral hemorrhage which fall under the care of the surgeon are nearly all of traumatic origin. They may be classed under three heads : {a) extradural hemorrhages, or those which occur between the dura mater and the skull ; (Jj) subdural, or those which take place between the dura and the brain ; and {c) cerebral, or those which take place into the tissue of the brain itself Extradural Hemorrhage. — The source of this form of hemorrhage is nearly always the middle meningeal artery, and the exciting cause is a blow or a depressed fracture. The artery is a branch of the internal maxillary and enters the skull throngh the foramen spinosum ; it then divides into an anterior and a posterior branch. The anterior follows the groove in the great wing of the sphenoid, and, reaching the ante- rior inferior angle of the parietal bone, turns upward toward the middle line of the head. The posterior branch passes over the squamous portion of the temporal bone, and thence to the posterior margin of the parietal bone. One or other of these branches is usually the seat of extradural hemorrhage — the anterior more frequently than the posterior. Symptoms. — There is one symptom of intra-cranial hemorrhage which is worth all the rest combined. // is a period of consciousness after the first shock of the injury, folloived by paralysis or unconscious- ness. Thus, a person receives a blow upon the head, and, falling to the ground, remains for a time unconscious, owing to concussion of the brain. From this he soon recovers, but at the end of several hours, or it may be one or two days, symptoms of compression appear, manifested by paralysis of a limb or gradually increasing stupor. At the time he received the blow a branch of the artery was ruptured, and the blood began to collect and form a clot upon the surface of the INJURIES AND DISEASES OF THE HEAD. A.'Jl brain. At first the brain could tolerate the moderate pressure thus produced, but when the clot became larger the symptoms of compres- sion began to be apparent. When paralysis appears it is upon the side of the body opposite to the brain-lesion, and may involve a single move- ment or limb or take the form of hemiplegia. In some cases we can trace the course of the growing clot by the paralytic symptoms. Palsy of the muscles of the face, motor aphasia, paralysis of the arm, and later of the leg, would indicate that the clot began to form low down near the base and gradually ascended to the middle line. The patient becomes drowsy, and the drowsiness may deepen into coma. The pulse is frequent, and in contrast to it the respiration is slow and stertorous. If the clot tends to increase toward the base of the brain instead of upward, the pupil on the same side will at first be contracted, and afterward dilated and insensible to light. It occasionally happens that the hemorrhage takes place on the side opposite to the injury. In that case the injury and the paralysis will be upon the same side. Subdural hemorrhage cannot always be distinguished from the preceding variety. The pressure is not so great as in the extradural form ; hence the pressure-symptoms are not so clearly marked. The blood comes from the middle cerebral artery, from the vessels of the pia mater or cortex, or from the veins of the surface of the brain. When the motor area is the seat of subdural hemorrhage the para- lytic symptoms are the same as those observed in extradural bleeding, but less marked and indefinite. When the frontal lobes are involved the mental condition of the patient becomes changed, as shown by irritability of temper, loss of self-control, and sometimes insanity. Subarachnoid hemorrhage is not recognized by any symptoms which distinguish it from other forms of intra-cranial hemorrhage. The blood usually comes from the cortex itself, and, if it does not burst through the arachnoid, it spreads over the surface, filling the sulci and gravitating toward the subarachnoid space at the base of the brain. This form may be suspected if after a severe contusion the symptoms are local at first and rapidly become general, attended with convulsions and paralysis. Cerebral hemorrhage, or hemorrhage into the substance of the brain, probably occurs, in a slight degree, in most cases of concussion, but produces no definite symptoms. When a vessel of considerable size is ruptured, the blood is poured out into the ventricles and the case is one of apoplexy. Treatment of Intra-cranial Hemorrhage. — When signs of com- pression appear within a few hours after an injury hemorrhage may be almost positively diagnosticated. The treatment must be deter- mined by the question of localization. If the compression is general and no e.xact point can be fixed upon as the situation of a clot, we must be content with helping the flow of venous blood from the brain by keeping the head and shoulders slightly raised and by lessening the amount of cerebro-spinal fluid through the influence of purgatives. Formerly, venesection was resorted to, but its value is now considered doubtful. When the position of the clot can be accurately determined by local symptoms, it is an imperative duty to trephine the skull, remove the 474 SURGICAL JU A GNOSIS AND TREATMENT. clot, and litj^atc, if possible, the bleeding vessel. When the middle menintjeal artcr}' is the bleeding vessel, which is the case in the majority of injuries, the prognosis is not necessarily bad, and espe- cially if it is the anterior branch of the vessel which is injured. If there is a fissure of the skull along the line of this artery, it is more than likely that the bleeding point is just beneath the fissure, and the trephine should be applied accordingly. It must never be forgotten that the blow may be on one side of the head and the hemorrhage on the opposite side ; the paralytic symptoms in that case would be on the same side as the accident. In operating, therefore, the point for tre- phining must be chosen not from the position of the original injury, but by the localizing symptoms. Thanks to the observations of Kronlein, there is one point at which we are almost sure to find the clot, and that is one and a quarter inches behind the external angular process and on a level with the upper margin of the orbit (P1g. 203). Fig. 203. — Site of trephine opening to reach clot in hemorrhage from middle meningeal artery (Kronlein) : a,b, horizontal line through the meatus; c, d, on a line with the eyebrows; e,f, vertical line 3 to 4 cm. behind the ext. ang. process; g, h, at the posterior border of the mastoid process. A, the point to reach the anterior, and B, the posterior branch. This reaches the anterior branch of the middle meningeal. If there are dilatation of the pupil and other evidences that the clot is increasing downward, this opening must be made half an inch lower. Should we be disappointed by this exploration, we must immediately look for the clot at the position of the posterior branch of the artery. This is reached by trephining farther back — viz. on the same level as the former opening and just below the parietal eminence. When the clot is reached it presents the appearance of a dense, almost black coagulum bulging into the opening. This must be care- fully scooped out, and if the trephine opening does not give sufficient room, the bone must be further removed by Keen's or Hoffman's cut- ting forceps. Having got rid of the clot, the next and most difficult task is to find the bleeding point. If the blood keep welling up as fast as it can be sponged away, the carotid artery should be compressed, and sterilized water at a temperature of 110° should be applied to the INJURIES AND DISEASES OF THE HEAD. 475 wound. When the bleeding point is found, a catgut ligature should be passed around the vessel by means of a full-curved Hagedorn needle, the point of the needle being made to enter the dura mater at one side of the artery, and, passing under the vessel, emerge at the other side. The ligature is then tied so gently as not to rupture the vessel. Another difficulty in stopping the bleeding point is that the part of the brain occupied by the clot does not rise to the opening when the clot is removed, but remains depressed. This may require a further enlarge- ment of the trephine opening. Having found and secured the bleeding vessel, the wound is well cleansed and ample drainage provided for. The Operation of Trephining. — As this operation is a preliminary to nearly all the operations which can be performed on the brain and involves the technique of all cerebral operations, let us consider it in detail. It is indicated for the removal of a depressed bone in fracture of the skull, for intra-cranial hemorrhage, for the evacuation of cerebral abscess, for the relief of epilepsy or insanity, and for the removal of tumors. Preparation of the Patient. — The patient's head should be shaved as the very first proceeding, since his examination cannot be conducted satisfactorily without it. It is remarkable how scars, prominences, and depressions are revealed after removal of the hair. The nature of the lesion having been arrived at, not by a " snap " diagnosis, but after careful study of every feature of the case, the fissures or other land- marks are marked by an anilin pencil or by a stick of nitrate of silver. The head is protected by a suitable cap or silk handkerchief The day before the operation the scalp should be again shaven, thoroughly dis- infected, and wrapped in sublimate gauze. When the patient is taken to the operating-room a final washing and sterilizing is carried out. AncstJicsia. — The semi-recumbent posture is believed to lessen the amount of hemorrhage during the operation. Chloroform is un- doubtedly the best anesthetic. Raising the Flap. — Having mapped out the location of the fissures upon the scalp, it is very important that corresponding points should be marked upon the bone. The sharp point of a trocar or the center pin of a spare trephine is pushed through the scalp, and by rotary movement or a sharp stroke of a hammer is made to mark the bone. In any case the point to which the trephine is to be applied should be marked, and if the operation is to be over the fissure of Rolando, the upper and lower end of the fissure should also be marked. If there is already a wound in the scalp, this can be utilized and enlarged as required. In the uninjured scalp a suitable flap must be raised and the bone exposed. Formerly this was done by a crucial incision, but it had several disadvantages : four triangular flaps were constantly in the way and had to be held aside ; the application of sutures to close the wound was troublesome, and a weak point was left which was sure to come over the center of the opening, where the greatest support was required. A horseshoe flap is the shape which best fills all requirements. It should have its base below when practicable, as this secures better blood-supply. The incision goes through the pericranium, and the flap is raised by separating the pericranium from the bone. The scalp is 476 SURGICAL DIAGXOSIS AND TREATMENT. likely to bleed freely, but this is readily controlled by grasping its edges in hemostatic forceps. The operation can be made almost blood- less by apph'ing a stout rubber band around the scalp, just above the eyebrows and ears, but the advantage thus gained is more than lost by the copious hemorrhage that follows removal of the tourniquet. For holding the flap out of the way a stout silk thread can be passed through its margin and tied to form a loop. Trcphiiiino the Bone. — The skull is now exposed to view and is examined. If there is fracture with depression, it may be possible to introduce an elevator beneath the depressed portion and restore it to its proper place. If the bones are so interlocked as to make this impos- sible, the trephine must be used to get rid of the necessary extent of bone. When the object of the operation is to deal with an intra-cranial lesion a good-sized trephine is applied over the spot indicated by the mark which has previously been made on the bone. The point of the center pin hav'ing become well engaged, the trephine begins to cut through the bone by light rapid movements from right to left and from left to right. Care must be taken to keep the instrument at right angles to the bone, in order that it may cut through evenly, and as soon as the center pin has ceased to be necessary it is retracted and fixed with its thumb-screw. The bone-dust is at first dry, but becomes moist and blood-stained as soon as the outer table is cut through. The chan- nel made by the saw must be kept clear by occasionally using a sterilized toothpick or needle, and the instrument itself freed from debris by washing it in carbolic-acid solution. When the diminishing resistance gives warning that the bone has been cut through, the tre- phine is laid aside and the button of bone removed by gently elevating it. An improv^ement on the time-honored trephine has been devised by Leonard (Fig. 204). It has a fixed handle in which a shaft revolves, Fig. 204. — Leonard's improved aseptic trephine. and to which the force is applied through a double raised spiral by means of a sliding handle. By each upward movement of the sliding handle the shaft and trephine are caused to make three complete revo- lutions. The friction is less and the cutting more easy than in the ordinary treatment. A trephine opening to be of any utility should be not less than an inch and a half in diameter. Should this be found insufficient, the opening can be enlarged by rongeur forceps (Fig. 205). Before enlarg- ing, however, the dura mater is to be separated from the bone, for which purpose Poirier's (Fig. 206) or Horsley's dural separator (Fig. 207) can be employed, or a stout probe bent to a proper angle. INJURIES AND DISEASES OF THE HEAD. 477 Examination of the Brain. — The dura mater is now exposed, and the rule is to open it, for without this step a satisfactory examination of the brain cannot be made ; but it must be borne in mind that unless Fig. 205. — Hopkins's rongeur forceps. the most thorough asepsis is carried out the risk is greatly increased. The cicatrix which follows an incision of the dura may prove trouble- some, and should be taken into account. The membrane is divided Fig. 206. — Poirier's dural separator. Fig. 207. — Horsley's dural separator. with curved scissors a quarter of an inch from the edge of the bone, so as to form a flap, which at the end of the operation is replaced and stitched to the quarter-inch margin. The brain now lies in full view, and we must observe the following points : {a) The Degree of Tension. — Does the brain bulge into the trephine opening ? If so, there is an increase of intra-cranial pressure due to a tumor, an abscess, or excess of fluid in the ventricles. ib) The Color of the Brain. — Lividity or a yellowish tinge indicates a probable tumor beneath the cortex. An old laceration has a dirty yellowish-brown appearance. A dark purple substance, seen before opening the dura, forced up into the trephine opening and without pul- sation, would indicate subdural hemorrhage. {c) Pulsation. — With a moderate degree of compression strong pul- sation can be felt and the resistance is increased ; when the pressure is due to a large underlying tumor or abscess, pulsation is absent. {d) Faradization. — It is not advisable to spend much time in testing the motor-centers by faradization, but should it be deemed necessary 478 SURGICAL DIAGNOSIS AND TREATMENT. to follow this line of investigation, an ordinary faradic battery with a weak current is sufficient. A very convenient electrode is that devised by Keen (Fig. 2o8). Fig. 208. — Double brain-electrode (Keen) Operations on the Brain. — If the aim of the operation is the arrest of hemorrhage, the bleeding vessel can be secured by passing a full- curved Hagedorn needle through the brain-tissue and beneath the vessel, and tying the ligature with only sufficient tension to sto]3 the bleeding. A ligature drawn too tightly is sure to tear through the delicate tissues. If it is necessar>^ to remove a diseased portion of the brain-substance, the lines of incision should be made antero-poste- riorly, as in that direction they do not cut across motor areas, and are therefore less likely to produce paralysis. If a tumor is to be removed, the necessary incision through the cortex should be made at right angles to the surface of the brain. Closing the Wotmd. — When the removed portion of bone is in a healthy condition, it is proper to replace it. With this object in view the greatest care is necessary that the bone should be properly looked after. One assistant should have this matter as his sole charge. As soon as the bone is removed he should place it in a bowl containing a I : 2000 sublimate solution, and keep the bowl floating in water at a temperature of ioo° to 105° F. All bleeding having been arrested and the wound carefully dried, the flap of dura mater is replaced and stitched with a fine catgut continuous suture. The bone, if healthy, is cut into several pieces with rongeur forceps and laid upon the dura. The skin-flap is laid in position and stitched with catgut or silkworm gut. If the case is one of abscess, hemorrhage, or gunshot wound, a rubber drainage-tube should be placed in the position which will be most dependent when the patient lies in bed. The outer dressing is the same as for any other wound. Wounds of the Brain. — The brain, although admirably protected from ordinary violence, may yet be wounded by instruments or foreign bodies penetrating the orbit, roof of the mouth, or the cribriform plate of the ethmoid by way of the nose. Instruments, as sabers, bullets, knives, or bayonets, applied with great force, may even penetrate the skull and wound the brain. The wound of the brain in all these in- stances is a complication of the attending compound fracture of the skull. The symptoms are usually overshadowed by the fracture or they may be remarkably slight or slow in making their appearance. Such wounds are nearly always septic ; consequently there is evidence sooner or later of inflammation ; the patient complains of headache, and this is followed by the group of symptoms which attends cerebritis and ends in death. The cortex is, as a rule, the part that suffers, except when the wound is receiv^ed by the mouth, and then it is the base of the brain. In many cases the penetrating body, as a knife-blade or a piece of wood, is broken off and left within the cranium. Such a case came INJURIES AND DISEASES OF THE HEAD. 479 under my observation in which a splinter of wood about half an inch square and six inches in length was driven into the orbit ; the wood was immediately withdrawn, but a portion three inches in length remained in the brain, and was not discovered till three weeks afterward, when evidences of an abscess led the surgeon to operate. Sometimes the localizing symptoms, as paralysis of the face, the arm, or the leg, hemi- anopsia, aphasia, etc., may lead to a diagnosis of the position of the foreign body. Treatment. — The wound is to be thoroughly cleansed (the head having been shaved), all pieces of bone and foreign bodies removed, and every effort made to secure asepsis ; the dura mater, if practicable, should be united by sutures, a drainage-tube placed at the most depend- ent part of the wound, the scalp closed by sutures, and a full antiseptic dressing applied. Suppuration may follow in spite of all these pre- cautions ; abscesses should be watched for and promptly drained. V. INJURIES OF CRANIAL NERVES. The symptoms that indicate injury of the cranial nerves are due either to a lesion of the part of the brain which gives origin to the nerves or to injury along the course of the nerv^es themselves. The Olfactory Nerve. — The olfactory nerve begins at the tuber olfactorium in front of the anterior perforating space (Fig. 209). From Fig. 209. — Anterior and middle portions of the base of the brain (after Hirt) : F, frontal lobe; 7", temporal .lobe ; b.ol., olfactory bulb ; /r. (?/., olfactory tract; t.ol., tuber (trigonum) olfactorium; s.m., middle; j. /., lateral root; /., infundibulum (cut off); cm., corpora albi- cantia ; /./. a., anterior perforated space ; s.p. p., posterior perforated space. this point the nerve runs forward and slightly toward the middle line, ending in the olfactory bulb {b. ol). The bulb lies upon the cribriform plate of the ethmoid bone, and through the minute openings of this bone two sets of "fibers pass to be distributed over the mucous mem- brane of the nose. The deep origin of the nerve is not positively known, but authorities are generally agreed that there are three roots. The brain-center of the sense of smell is also a disputed point.
