The suture is intntdueed at right angles to the direetion of the wound, passing through eorresponding points on o})posite sides. The needles are })assed either with the free hand or are grasped and direeted by forceps-like instruments, needle-holders (Fig. 31). In so-called pedunculated .»«*^^W■<•<.^^■^e tend(tn may be established by means of an auxiliary operation, teno- plastij. From the side of one of the extremities of the divided tendon a small i)ortion is so freed that it ean be turned over toward the other ex- tremity, with which it is united by suture (Fig. 35).' Nerve-sutarey as first practised by Robert and Nelaton, may be enipk)yed in cases of recent injnries attended with division of nerves, as well as a secondary procedure after isolation and freshening of the divided extremities. The object of nerve-suture is the approximation of the Fig. 35. — Hiiter's tenoplasty. transverse edges of the divided nerve-strand. To this end fine threads are passed either directly through the substance of the nerve, and the transverse surfaces of the divided extremities are brought in apposition, or the ex- tremities are so united that they overlap one another upon their lateral surfaces (paraneural siitare). The extremities of the divided nerve may be so united that the sutures are not passed through the substance of the nerve, but through the surroundinir connective tissue. In this way the extremities are brought indirectly in ap- proximation (perineural suture). Neuroplastj/, based upon the same principle as the tenoplasty of Hiiter, may also be employed successfully in the union of divided nerves. ^ Instead of silk, we can employ kangaroo- tendon or chromic gi't. — Ed. 52 OPERATIVE SURGERY. The position and fixation of the extremity operated upon should prevent all disturbance of the nerve after the operation. The union of hones is effected by suture in a manner analogous to that in which the soft tissues are united (Fig. 36), except that wire is employed with especial ad- vantage as suture-material. The channels for the pas- FiG. 36.— Suture of the patella with wire. sage of the sutures must be made by means of a drill or an awl. The Avires are fastened by twisting their ex- tremities together. Braces or clamps also may be em- ployed in the same way as they are used in securing boards in scaffolding (Gussenbauer's clamp, Fig. 37). Severed bones may further be united by means of nails or ivory pegs (Fig. 38). Nails may also be driven into REUMos or Till-: rissvKs. 63 the bone tlirouuli the ovcrlyiiii^ soft tissues in m-ilci- U) maintain the iVaL»;nients in :i|)|)<>silirtion of the muscular layer, as in this way the serous folds are made firmer and can be brought in closer approximation. Suture of the bI((fJ(Jer, when the injury involves the intraperitoneal ])ortion of this viscus, is effected upon principles similar to those that have been just laid down, except that in this event it is advisable, in order to avoid incrustations, to use catgut instead of silk as the suture- material. One row of sutures will accurately approxi- mate the muscular layer of the bladd(M', which is often from one-half to one centimeter thick. It is customary to exclude the mucous membrane from the suture. A second ro\y of Lembert's sutures unites the serosa. In 56 OPERATIVE SURGERY. the closure of wounds of the bladder, as in closure of those of the intestine, the continuous suture or closely applied knotted sutures may be employed. Wounds of the extraperitoneal portion of the bladder are to be so united that the thick layer of muscular tissue is brought in firm apposition by means of catgut sutures, with exclusion of the mucosa. The various methods of suture for closure of wounds of the bladder have been largely supplanted by the simple method just described. Wounds of the gall-bladder may be closed by suture in a manner analogous to those of the bowel. LIGATIOX OF VESSELS IS coyTiyUITY. 57 I. OPERATIONS ON THE EXTREMITIES. I.

This variety of ligation of vessels in continuity will n«»\v l»e considered. Indications. — {!) Injuries. — {a) ^^iab-woundsj gun- shof-icoundsy contused icoundsy and lacerated wounds of the large arteries. If possible, ligation is to be under- taken at the site of injury. This is dit!icult in lacerated tissues suffused with Ijhxxl, when the wound is uutavorablv situated, or when the artery is injured directly at its origin from a main branch. (b) Subcutaneous laceration of large vessels; also when ligation at the site of the lesion is impossible. (2) Hemorrhages fr(.>ni suppurating wounds through erosion of laro:e vessels : further arterial hemorrhagre from gangrenous tissues or dismteo-rating new-growths. (3) In order to render an operation bloodless the main arterial branch of the operative area may be previously ligated — e. g.^ the lingual artery preceding extirpation of the tongue, the femoral artery preceding enucleation of the hij>-joint, and preceding extirpation of cavernous tumors. (4) In order to induce retrogression of morbidly altered organs or neoplasms the blood-supply is cut off by ligation of the main artery — e. g.y of the thyroid artery in the presence of goiter, of the spermatic artery in the presence of tumors of the testicle, of the internal iliac artery- in the presence of hypertrophy of the prostate, etc. In the same category belongs the treatment of elephantiasis of the les: bv ligation of the external iliac or the femoral 58 OPERATIVE SURGERY. artery, with -which some surgeons have secured good results.^ (5) Aneurysms. — According to the method of Hunter, the afferent artery is ligated in the treatment of aneurysm, but on account of the supply of bh)od to the aneurysmal sac throuoh the collateral circulation this method is not so reliable as that of Antyllus. In cases of trigeminal neuralgia resisting other operative measures, ligation of the carotid artery has been repeatedly practised (Patruban). The treatment of epilepsy by ligation of the vertebral artery has also been proposed. Method of I^igation. — At definitely determined points upon the surface of the body the skin is divided and with careful protection of important structures the sheath of the vessel is exposed. This is then opened, and the artery, separated from the accompanying veins for a small portion of its extent, is raised from its bed for the purpose of ligation. Two ligatures are now applied, and the artery is divided transversely between them with a sincrle cut of the scissors. The wound in the skin is closed by suture. The cutaneous incisioni< are made in selected situations in a definite direction so as to render possible access to the artery by the sliortest route. Usually the incision in the skin corresponds witli the course of the artery. Thus, in the extremities this incision, with a few minor exceptions, coincides with the longitudinal direction of the vessel. In order that the incision in the skin may be placed in the proper situation, it is necessary to make careful scrutiny of the surface of tlie body. To facilitate this, prominent, readily palpable points of the skeleton, as well as nuiscular prominences, and the intervening depressions, are selected as landmarks. 1 In some regions extirpation of a vessel is better tlian ligation, if we wish to arrest the growth of a tumor. Davvbarn has recently pointed out that ligation of the external carotid is of slight value in sarcoma of the tonsil, as the anastomotic circulation is so quickly established, but extirpation of this vessel causes great shrinking of the growth. — Ed.

Tlie incision ior exposure of the internal iliac artery will meas- ure from 15 to 20 cm. (6 to 8 in.), while that for the ra- dial artery at the wrist-joint need not he more than 1 (jr 1.0 em. (^ or ^ in.).^ A\'hen the skin and the suhcutaneous connective tissue have heen penetrated (the base of the wound is no longer moved with movements of the margins of the skin), the sheath of the vessel is carefully approached by dissection either w ith the free hand, between two pairs of forceps, or with the aid of the grooved director. Muscles, nerves, and veins that obstruct the way are displaced with 1)1 unt hooks. If a vessel prevents access to the arter}', it may be ligated in two places and divided between. The sheath of the vessel is detached from the artery for a short distance by blunt dissection with anatomic forceps, or it is divided upon the grooved director, in accordance with the character of the tissues. After the sheath has been opened, either a single vessel will be exposed .], the ligating instrument, armed witli a ligature, is passed beneath the artery, the ligature wound about the vessel and tied. A second ligature is applied in similar manner at about a distance of 1 cm. (^ in.^ from the first, and, between the two, the artery, raised from its bed, is cut squarely with a single stroke of the scissors. The divided ends of the vessel retract somewhat in either direction (Fig. 39). The application of two ligatures and cutting between possess some advantages, but are not always necessary. The retraction and the relaxation of the extremities of the divided vessel afford more favorable conditions for thrombus-formation, through narrowing of the lumen, than simple occlusion of the lumen of the vessel. Beside, by division of the vessel Ijetween the ligatures a view is obtained of the posterior wall of the artery, and in this way ligature of the artery just in advance or just beyond the orio^in of a lateral branch can be avoided. Either contingency is equally unfavorable to thrombus-forma- tion. The small wound made is closed with knotted sutures. The knot of the ligature is tied as follows : after the ligature has been made to surround the arter}' the free end on either side is grasped with the fingers of the cor- responding hand. Before the knot is tied the ends are so crossed that the right passes behind the left and is re- ceived into the left hand, while the left passes in front of the right and is received into the right hand. When the extremities have been thus crossed a sinq^le knot is tied. Before the second knot is placed upon the first the free extremities must again be changed and in such a manner that that upon the left is passed in front of that upon the 62 OPERATIVE SURGERY. right. Tlie sailor^s knot (Fig. 40) thus fijrmed is more secure than the ordinary granny^ s knot (Fig. 41). If in the first part of the knot the extremities are twisted twice, instead of once, there results the so-called surgical knot (Fig. 42). The sailor's knot is employed not only in the applica- tion of ligatures, but whenever it is desired to tie a secure knot. lyigations in the Upper Extremity. — The arter\^ supplyino' the arm, the forearm, and the hand may be Fig. 40. — Sailor's knot [reef-knot].

It would be a mistake to look for the vessel in the axil- lary cavity, which forms a space filled with flit, connective tissue, and lymphatic glands next to the lateral wall of the chest. The artery, which lies close to the humerus, is therefore to be looked for in relation with this bone at the apex of the axillary cavity. The incision is made along the line of the coracobrach- ialis muscle in the continuation of the internal bicipital sulcus (Fig. 43). After the subcutaneous connective tissue has been passed the thin fascia of the arm will be exposed, through which the fibers of the coracobrachial muscle will be visible. The fascia is divided upon the grooved director and the lower (inner) lip of the wound in skin and fascia retracted with tenacula. There now comes into view the median nerve embedded in loose cellular tissue, and this is drawn out of the way with a simple blunt hook. The artery is now exposed and can be readily isolated and ligated (Plate 2). Care must be taken that the ner^^e alone is grasped and drawn out of the way, as otherwise the artery, which lies directly behind it, may also be displaced and removed from the field of vie\v.

'I'liis small nerve can scarcely be eonfoundeil with the median nerve, which comes into view after fnrther retraction of the lower (inner) margin of the wonnd. The artery is accompanied by one or several, sometimes by a whole ])lexus of veins. Ligation of the Bracliial Artery. — The continuation of the axillary artery from the surgical neck of the humerus to its point of division at the flexure of the elbow is known as the bracJikd (irtcry. The vessel lies in the in- ternal bicipital sulcus, and it is often accompanied by a network of veins. The median nerve lies over the upper half of the artery, which it conceals, while in their fur- ther course the nerve lies upon the ulnar side of the ves- sel. The basilic vein, which likewise lies in the internal bicipital sulcus, is separated from the group of large vessels and ni^rves by the fascia. The sheath of the vessel consists of loose cellular tissue. The patient occupies the same position as in ligation of the axillary artery. The incision is made at about the middle of the arm, slightly over (external to) and parallel with the internal bicipital sulcus (Fig. 43). Skin and subcutaneous connective tissue are divided and the fascia of the biceps muscle is opened in the same direction and throughout the same extent. The fibers of this muscle must be clearly exposed to view. The lower (inner) lip of the wound in the fascia is drawn downward (inward) with a tenaculum and the median nerve thus exposed. The nerve is lifted from its bed and drawn aside with a blunt hook, when tlie brachial artery is exposed accom- panied by veins. The artery is isolated by means of two pairs of forceps and is ready for ligature (Plate 2). The rule to make the incision somewhat above (ex- ternal to) the bicipital sulcus in order to reach the median nerve below is to be recommended on account of the difficulties encountered in reaching the artery 5 66 OPERATIVE SURGERY. throiigli a mass of structures, includinu: the greater in- ternal cutaneous nerve, the median nerve, and the ])asilic vein, when the incision is made directly over the vessels and nerves. If the incision is made below (internal to) the bicipital sulcus, an inexperienced person may err by failing to recognize the exposed ulnar nerve and looking in vain for the artery behind it. The relations bet\\'een the median nerve and the brachial artery are varia])le within certain limits. In rare in- stances the artery lies in front of the nerve. In cases of high division of the radial and ulnar arteries one of the vessels lies in front of and the other behind the nerve. The presence behind the median nerve of an artery pro- portionately small, as compared with the rest of the body, is suggestive of such high division of the brachial artery. Ligation of the Cubital Artery. — The continuation of the brachial artery in the iiexure of the elbow is known as the cubital artery. The vessel lies in the internal cubital sidcus, and, covered by the aponeurosis of the bi- ceps muscle, is embedded in the depression between the pronator radii teres and the biceps. The artery is in this situation accompanied by two symmetrically placed veins. The median nerve does not occupy the same intimate re- lation with the artery as it does higher up, but lies at some distance upon the idnar as})ect of the artery. Sepa- rated from the artery l)y the bicipital fascia and situated subcutaneously is the cubital plexus of veins (median ba- silic, median cephalic), which communicate in the flexure of the elbow with the veins accompanying the artery. The simplicity of the relations existing in the arm in consequence of the prominences formed by the biceps and the triceps and the presence of the internal and external bicipital sulci, is replaced at the flexure of the elbow- joint by complexity resulting from the presence of the two large groups of forearm-muscles. The s])indle-shaped belly of the biceps, which gradually diminishes in size, is separated by a sulcus upon the right and the left respec- tively from the muscular prominences of the extensors LIGATION OF VESISELS IN CONTINUITY. 67 and Hoxurs »)!' tiic fbrcarin, wliidi oricrinate in this situa- FiG. 44.— Arrangement of the muscles in the upper extremity : Shi, internal l)icipital sulcus; f^be, external bicipital sulcus; Sci, in- ternal cubital sulcus; ^V, radial sulcus; Sn, ulnar sulcus. tion.

The inner furrow of the flexure of the elbow is bounded by the biceps or the brachialis internus and the pronator radii teres, the outer by the biceps and the supinator longus. The internal bicipital sulcus is covered by the radiating aponeurosis of the biceps (Fig. 44). To ligate the bicipital artery the forearm is extended at the elbow-joint and held in a position of maximum supina- tion. Information as to the direction and situation of the internal bicipital sulcus is sought through palpation. The incision is made in the continuation of the internal bicipital sulcus and passes from within and above downward and outward, corresponding to the direction of the internal cubital sulcus (Fig. 45). After division "of the skin con- sideration should be given to the network of veins at the flexure of the elbow. When possible the way is cleared bv retraction of the veins with blunt hooks. The shining aponeurosis of the biceps muscle now appears in the wound and it is divided upc^n the grooved director in the direction of the cutaneous wound. The artery lies im- mediately beneath the aponeurosis, accompanied by two veins, in a bed of loose connective tissue. The median nerve lies to the ulnar side of the artery (Plate 3). In case of high division of the brachial artery one or both branches may lie ujwn the bicipital fascia. This possi- bilitv is to be thouglit of when bleeding from the veins at the flexure of the elbow is to be undertaken, or when one of the median veins in this situati(m is to be exposed and opened for infusion with a saline solution or for transfusion of blood. /h..inst.

The vessel is grasped with a pair of anatomic forceps and snipped with the scissors, without being totally divided. The vein is now closed by ligature on the peripheral side of the incision. Through the opening thus made the cannula is introduced into the vein in a cen- tripetal direction and fixed. To make the infusion a sterilized rubber tube armed with a funnel is most advantageously employed, attached to the cannula.

The forearm is honnded upon the ulnar side by the flexor carpi ulnaris, u})ou the radial side by the supinator longus. Between the tendons of these muscles and the mass of the flexofs of the fingers there is thus formed in the lower third of the foreariu upon either side a longitudinal furrow or depression which is used as a guide in finding the radial and the ulnar artery respec- tively (Fig. 45). The r(((Vml arferjf corresponds in its course with the direction of the radius. In the upper third of the fore- arm the artery lies in close relation with the supinator longus muscle and is deeply situated. In the lower third it lies more superficially in the sulcus between the tendons of the flexors and that of the supinator longus. Just above the wrist-joint the artery, with its accompanying two veins, lies upon the lower extremity of the radius, covered only by skin and the thin fascia. The ulnar artery, after it?s origin from the brachial, crosses the common head of the flexors, among which it pursues its course, until it reaches the tendon of the flexor carpi ulnaris, along the inner side of which it reaches the wrist-joint. The typical situation for the ligation of both arteries is just above the wrist-joint. The forearm is placed in a position of maximum supination, with the hand in slight dorsal flexion. To expose the radial artery an incision is made just above the wrist-joint corresponding to the de- jH'ession between the tendon of the su])inator longus and those of the flexors (Fig. 45). After division of the skin, the artery, covered by delicate translucent fascia, is seen, situated between two veins. After division of the fascia the artery can be isolated and ligated (Plate 2). The ulnar artery is reached through a short incision in the ulnar sulcus just above the wrist-joint somewhat to 72 OPERATIVE SURGERY. the mdial side of the readily palpable tendon of the flexor carpi ulnaris.

The depression thus formed between the extensors and the abductors (Fig. 47) sei-^'es as a path- way for the vessels passing over the margin of the peh'is and corresponds in its direction with the course of the vessels. The sartorius muscle bridges over this gutter (Fig. 48) and constitutes thus an important landmark in locating the vessels. The femoral artery, the continuation of the external iliac, emerges from the pelvis under Poupart's ligament at a point midway Ijetween the symphysis pubis and the anterior superior iliac spine. The femoral vein at its entrance into the pelvis lies to the median side of the artery. The artery passes downward and inward, and in its course follows the depression between the extensors and tlie adductors. From the middle third of the thigh onward the sartorius muscle lies in front of the artery, which in this situation is covered by the tense fibers of the deep layer of the fascia lata. The artery, with its accompanying vein, enters the popliteal space through an opening in the adductor magnus (Hunter's canal), at the junction of the middle and lower thirds of the thigh. The femoral vein below Poupart's ligament lies to the median side of the artery. In the further cour.-e of the vessels they cross in such a way that the vein comes to lie behind the arterv.

Ligation of the Femoral Artery below Poupart's Liga- ment. — The incision into the skin is made parallel N\'ith the axis of the thigh from Poupart's ligament doNvnward for a distance of from 5 to 8 cm. (2-3 in.). The upper extremity of the incision corresponds with a point mid- way between the symphysis pubis and the anterior supe- rior iliac spine (Fig. 49, a). After division of the skin and the fatty connective tissue careful dissection is made downward in a vertical direc^tion until the sheath of the vessels is recognized by its fibrous structure and whitish appearance. The sheath is divided upon a grooved director and the artery isolated for a short distance with two pairs of forceps and raised from its bed. The femoral vein can be brought into view upon the median side of the artery. The crural nerve is some distance to the outer side of the vessels, covered by the deep layer of the fascia lata. II.

In applying the saw the nail of the thumb of the left hand is placed vertically upon the denuded bone (Fig. 58), and the support thus atibrded is used as a guide for the blade of the saw. At first the saw is manipulated without pressure. Only after a groove has been formed in the bone may the sawing be proceeded with more mpidly, with the application of a certain degree of press- ure. An assistant, stationed at the periphery, holds the extremity in a position of extension and aims to keep the sawed surfaces apart in order that the blade of the instru- ment shall not become impacted. The irregular edges of the divided bone are trimmed by means of bone-forceps, and small projections are cut off. After complete removal of the amputated part atten- tion is directed to the definite control of hemorrhage. The main arterial and venous trunks, recognizable by their position, are isolated in the stump with the aid of two pairs of dissecting-forceps, clamped in sliding-forceps, and ligated. In addition to the main arterial branches all vessels that can be seen running in the connective-tissue interstices of the muscles are also ligated. The Esmarch bandage can now be freed, and it may be necessary to apply additional lig-atures. Parenchymatous hemorrhage is controlled by compression. The care of the icound has for its object accurate ap- 110 OPERATIVE SURGERY. proximation of the wound-surfaces, with the avoidance of dead spaces, as well as exact approximation of the margins of the skin. The muscles may be separately united by buried sutures or large areas of surface by means of gauze-pad sutures, while the skin is closed by superficial Fig. 64. — Cutaneous suture after amputation of the leg through a circular incision. knotted sutures, or by a continuous suture (Figs. 64 and 65). If it has been possible to effect the amputation under complete aseptic conditions, the wound may be closed entirely by suture ; otherAvise drains may be brought to the surface out of the depth of the wound. A like pur- pose may be served by the introduction of strips of sterile or antiseptic gauze. In the performance of exarticulation the same general principles may be observed as in the performance of amputation. The operator stands at the periphery of the extremity, holding the part to be removed in the left hand, while the exarticulation is eifected with the right. In the majority of cases the joint is opened from its ex- tensor aspect. Flap and oval incisions are generally employed, less commonly circular incisions, with the A MP I TTA TIONS A NJ) KN UL 7> KA TIONS. Ill formation of a cuff.

The methods of performing exarticulation are in part so carried out that Avith the last incision of the knife, which passes from the Avound and forms tlie flap, the main vessels are severed. During the process of division the artery may be closed by pressure with the finger in the wound. A method of exarticulation (Esiliarch) often employed with large joints consists in circular division of the soft parts in the upper third of the extremity down to the bone after application of the Esmarch bandage. The bone also is divided at the level of the incision through the muscles. After ligation of the vessels the constrict- ing band is removed. A longitudinal incision is made through the soft parts down to the bone from the joint to the primary wound in such a w'ay that large vessels and nerves are not divided. With the wound thus made held open by means of hooks, the joint is opened and the remainder of the bone removed with the utmost care. This combination of circular and longitudinal incisions constitutes a variety known as the racket-incision. Amputations and Bxarticulations of the I/Ower Extremity. — Amputation of the Leg. — The removal of the leg may be undertaken at varying levels. It was formerly the custom to amputate the leg under all cir- cumstances in its upper third at the site of election. This method had for its object the use of a wooden leg, upon which the flexed knee Avas comfortably received after the wound had healed. At present, hoAvever, the principle is folloAved to be as conservative as possible in amputations of the leg, and in the remoA^al to take the greatest care of tlie healthy portion of the extremity. For this reason amputations are no longer performed at the site of election, but at the site of necessity. Among the methods of amputation of the leg employed are the circular incision in two steps, Avith the formation of a cufF; and A^arious forms of flap-operations: tAvo lateral tegumentary flaps; two lateral musculotegu- mentary flaps ; one anterior tegumentary periosteal flap ; and a posterior short musculotegumentary flap from the - 1 ^frl 'T. 1 77' K\s .

Amputation of the Leg with a Circular Incision in Two Steps. — An assistant rotates the leg towanl the operator and a circular incision is made throuirh the skin, begin- ning at a [)oint most remote from the ojx*rator, and pro- gressing toward himself, until the entire circumference of the part is dissected and a cutf is formed. When this has been separated for a sufficient distance all around and folded back the layer of muscles is divided. The incision through the muscles of the calf is made in three steps. Finally the muscles upon either side of the interosseous ligament are divided. This complex incision should be made exactly in the same plane, .so that the vessels are not divided at varying levels. In making the figure-of-eight incision the knife is placed horizontally, with its heel upon the upper surface of the tibia, so that its pointed extremity is directed toward the operator. It is steadily held in a horizontal position and drawn from heel to toe, introduced into the interosseous space close to the tibia up to its handle, and the soft tissues between the two bones divided. The fibula being reached, the knife is drawn from heel to toe around this bone and passed horizontally ag-aiu into the interosseous space, with its point directed from the ope- rator and its blade upward, dividing any remaining mus- cular fibers from the fibula toward the tibia. The ope- rator now introduces the index-finger and t-he thumb of his right hand into the wound and grasps the intero.sseous ligaments to assure himself that all of the muscles have been transversely divided. Before the saw is used the assistant rotates the member inward. The periosteum is detached from the bone with the raspatory- at the line of division. The saw is applied upon the til)ia in such a manner that the fibula also is brought within the range of its action. A groove is first carefully sawed in the tibia, and when the blade of the saw has thus secured a good d 114 OPERATIVE SURGERY.

The stump thus made shows the cross-section of the two bones, with the interosseous ligaments stretched between them. Anteriorly, lying upon the ligament, is the group of extensors, while upon the opposite side lie the flexors. Surrounding the fibula the peroneal group of muscles is visible. The powerful mass of the calf-muscles forms the most superficial layer upon the flexor aspect. Between this and the flexors pass the posterior tibial and peroneal arteries. Lying upon the anterior aspect of the interosseous ligament is the anterior tibial artery. The center of the field is occupied by the tibialis posticus mus- cle, which is a useful landmark in looking for the vessels. In front of this, but separated by the interosseous liga- ment, is the anterior tibial artery, and closely behind it are the posterior tibial and peroneal arteries to the fibular and tibial sides respectively. Flap-amputations of the Leg. — Two Lateral Tegument- ary Flaps of Equal Size. — The base of the flaps corre- sponds with the level at which the bones are to be di- vided. Anteriorly the margins of the flaps meet in the line of the crest of the tibia.

After the anterior flap has been dissected to its base the bone is raised and a shorter arched flap con- sisting: of the skin and the muscles of the calf is formed u]X)n the |X)Steri(ir aspect of the leg by an incision from without inward. The muscles of the interosseous space are then divided and the bones are sawed through in the usual manner. A ft'uiffle lateral jfap is made correspond i ugly longer and with a broader base. It may be constituted of skin, on the inner side of skin and periosteum, or finally of skin and muscle. When the tiap has been dissected a circular incision through the skin is made upon the opposite por- tion of the circumference of the leg unitintr the extremi- ties of the flap and after retraction of this the muscles are divided in the usual manner. To increase the su})poning power of the stump follow- ing amputation of the leg Bier, after healing of the woimd, removes a wedge-shaped portion of bone above the level of the stiunp, so that the lower extremity of the latter can be turned forward and upward through an arc of ninety degrees and be permitted to unite in this position. By this means closure of the medullary cavity is efl^c^'ted and the supporting surface is formed of healthy, well-padded skin, free from cicatrices, whose muscles do not undergo atrophy by reas<»n of preserving their natund attachment to the bone. The principle upon which the method is based is illustrated l)y the accomi)anying diagrammatic representation (Fig. 69). The medullary cavity of the divided bone may, according to Bier, be closed also with 118 OPERATIVE SURGERY. a loose piece of periosteum or Avith a foreign body, such as stanniol-paper. Supramalleolar Amputation of the Leg by Syme's Method. — The ankle-joint is opened and the bones of the leg divided just above the malleoli and the wound covered Avith a cutaneous flap obtained from the heel. The patient occupies the dorsal decubitus. The foot is raised above the horizontal and the operator stands to its peripheral side. Grasping and fixing the foot by the heel Avith his left hand the operator makes an incision, ahvays begin- ning on the left side, from the apex of the malleolus ver- tically toAvard the sole of the foot, then transversely Fig. 69. — Diagrammatic representation of amputation of the leg after the method of Bier. through the sole and again vertically upward to the other malleolus, dividing the tissues down to the caicaneum (stirrup-incision). A second incision, nuide over the an- terior aspect of the ankle-joint unites the extremities of the first, Avith which it makes a riglit angle and it also extends down to the bone. This incision should open the joint betAveen the trochlear surface of the astragalus and the lower extremity of tlie ti])ia and the fi])ula. In order to expose the joint fully the lateral ligaments must be divided on either side. The incision through the capsule has the folloAving form : / ~\ , the short limbs passing through the lateral ligaments. Only after the lateral ligaments (at the outer malleolus, the anterior and posterior astragalo- AMPUTAI loy.s , 1 M) KX UCLEA TIONS. 119 fibular, and the calcaneofibular ; at the internal malleolus, rhe deltoid liiranient) have been divided will tlie head of the astragidus l^e free, even with .-flight plantar Hexion of the joint. If the posterior wall of the capsule be divided, the upper surface of the ealeaneuni comes into view. The tuberosity of the calcaneus is freed from its coverings by vigorous incisions made vertically upon the bone, with the foot bent in maximum plantar flexion (Fig. 70j. When Fig. to. — Amputation of the foot by the method of Syme : enucleation of the tuberosity of the calcaneum from its coverinors. the foot is thus freed and detached the lower extremities of the tibia and the fibula are freed from the soft tissues, surrounded by a circular incision, and sawed through transverselv. The operation is attended with certain disadvantages, the excavated heel-flap not being properly adapted to approximation with the leg, while the excavation is further favorable to the accumulation of considei-able quantities of secretion. Although Syme's operation no longer receives the recognition which was formerly accorded it, it still deserves con- 120 OPERA TIVE S UR GER Y sideration, as it represents the predecessor of a number of admirable operations (PirogotI'.

The operator occupies the same position as in the operation of Syme and the incisions throngli the skin are made in a similar manner. The operator fixes the foot with his left hand and, beginning on the left side, cuts from* the apex of one malleolus ver- tically toward the sole of the foot (Fig. 72j, then trans- FiG. 72 — PirogoflTs amputation : cutaneous incisions. versely through the sole, and again vertically upward to the ajX'X of the other malleolus, dividing the soft tissues down to the bone (stirrup-incision).

In effecting this division, especially upon the inner aspect, the incision should be made close to the astragalus, in order to avoid injuring the posterior tibial artery. After the joint has been freely exposed the posterior wall of the capsule comes into view, after division of which the upper surface of the tuberosity of the calcaneum is exposed. The operator, who until now has stood at the periphery of the foot, changes his Fig. 73.— PirogoflTs amputation : division of the calcaneum with the saw. position, grasps the foot with his left hand and applies the saw to the upper surface of the tuberositv of the cal- caneum (Fig. 78). This process is divided in a plane corresponding to that of the stirru])-ineision, when the foot appears to be separated. The lower extremities of the tibia and the fibula are prepared for division with the saw, the soft parts upon the posterior aspect being first dissected close to the bone. This incision demands es- pecial care iii order to avoid division of the posterior AMPUTATIOyS ASD ENVCLEATIOSS. 123 t- r.

Upon the anterior surface it suffices to di.splace the ten- dons, when the bones of the leg may be divided circularly 126 OPERATIVE SURGERY. just above the malleoli. In sawing through the bones the leg is held horizontally, the operator standing as if amputating, with the member to be amputated to his right. An assistant grasps one of the malleoli with Lan- genbeck's forceps, when the division of the bone trans- versely to the longitudinal axis of the leg may be pro- ceeded with (Fig. 74). The stumps of the tendons are grasped with forceps and divided with scissors at the level of the wound. The vessels are secured by ligatures. The only vessels concerned are the anterior and posterior tibial arteries. The first is readily found upon the anterior sur- face of the tibia at the side of the tendon of the extensor hallucis. If the successive steps of the operation have been properly followed, the posterior tibial artery will be found to have been divided on the inner aspect of the heel- flap, somewhere about the middle of the vertical limb of the stirrup-incision. In closing the wound the heel is moved through an arc of 90° and the sawed surface of the calcaneum brought in simple apposition with that of the tibia or fixed by bone-sutures or jDcrcutaneous pegs. The cutaneous wound is united transversely (Fig. 75). The operation of Pirogoff has undeniable advantages over deep amputation of the leg, as exemplified by Syme's operation. The shortening is reduced to a minimum by the preservation of the posterior extremity of the calca- neum, which forms a prolongation of the bones of the leg. The strong, well-cushioned skin of the heel makes an admirable walking-surface, while the cicatrix does not lie within this area. Pirogoff in his first communication upon the subject had already called attention to the fact that after making the flrst incision into the sole of the foot the division of the calcaneus could be proceeded witli immediately from the sole (Figs. 76 and 77), and exarticulation at the ankle- joint next effected. He also had made the suggestion to give an oblique direction to the heel-flap in order to bring a larger portion of the calcaneum and the skin of the AMriTA TlOys AMJ Jjy UCLEA TIONS. 12' Fig. 76. — Giinther's modification of Pirogoff's amputation : division of the calcancum from the sole of the foot.

As a matter of course, the cuta- neous incisions are to be modified accordinsrly. The stirrup-incision will pass from the posterior boundary of the malleoli, not vertically downward, but obliquely for- ward toward the sole, so that a larger portion of the skin of the sole is contained in the heel-flap. The stump is thus changed in so far that not only does the tnl^erosity of the calcaneum form the walking-surface, but also a portion of the sole, the natural walking-surface, serves as a su})port for the stump. The walking-surface becomes still broader if the calca- neus is divided almost horizontally in accordance with the modification of Lefort (Fig. 80). The stirru{>- incision passes obliquely forward to Chopart's joint, while the dorsal incision forms a flap with its convexity directed forward, and it extends also to the line of Chopart's joint. The dorsal flap is dissected back, the ankle-joint opened, and the calcaneum sawed through from its tuber- osity forward in the direction of the cutaneous incision into the calcaneocuboid joint, the foot being held in a position of maximum plantar flexion. The foot is now separated at Chopart's joint and tlie lower extremities of the tibia and fibula are divided in the manner described. Bruns recommends horizontal divisi(^n of the calcaneinn, though in an arched direction. The sawed surface of the calcaneum is thus concave, while that of the tibia pre- sents a corresponding convexity. 132 OPERATIVE SUBGERY. Tlie limitations of Lefort's modification are naturally narrower than those of the typical operation of PirogofF. If the calcaneum is perfectly healthy, and tliis is a neces- sary condition for the employment of Lefort's o]^)eration, it would beem preferable to select the less serious pro- cedure of exarticulation at Chopart's joint. As a preliminary step in the performance of Pirogoflf 's operation di- vision of the tendo Achillis (AchVloteuotomy) is undertaken. The ten- don is divided, either through an open wound or subcutaneously, in a transverse direction, a finger's breadth above its attachment to the tuber- osity of the OS calcis. In performing subcutaneous tenotomy the knife ''tenotome) is passed through the skin and the tendon is divided by cutting either toward or from the skin. Under the condition fii-st named the operator grasps the tenotome, as a table-knife is held in paring fruit, with the flexed four fingers of the right hand, while the thumb is supported on the heel (Fig. &lj ; the knife is passed from right to left in front of the tendon. The latter is subjected to passive tension and is divided by short rocking movements of the knife toward the thumb, which is placed upon the tendon as a guide and to aftord resistance (Fig. 62). The jerk with which the extremities of the divided tendon separate indicates the completion of the operation. When, on the other hand, the tendon is to be divided from without inward the foot is so adjusted that the tendon is completely relaxed. The tenotome is grasped between the thumb, the index, and the middle finger and introduced upon the flat, from right to left, between the skin and the tendon 'Fig. 12 , The tendon is thus brought beneath the blade of the knife and is gradually divided by rocking movements, while an assistant subjects it to maximum tension by corresponding movement of the joint.

Then the lateral ligaments are completely severed until the joint is fully opened. Next a flap is formed from the plantar tissues by an incision from the wound outward. The length of the flap will be governed by the transverse extent of the exposed bone.

The incision then runs ])arallel with the longitudinal axis of the int of origin. The joint is exposed upon its dorsal aspect by dissecting the two sides of the oval, and opened transversely, when removal may be effected after division of the plantar tendons. Amputation of a Toe through the Metatarncd Bone. — An oval incision is made, its ajx^x corresjx)nding Avith the point at which the metatarsal bone is to be sawed thr(jugh. The incision passes longitudinally over the metatarsus beyond the metatarsophalangeal joint. It then passes around to the flexor as}xct and back again on the opj)osite side, to return to its point of origin. The nietatarsus is dissected free in the course of the lontjitudinal inci^ion and divided with the phalangeal saw or the chain-saw. The distal extremity is grasjx'd and enucleated, and if this pro- cedure has been carried out to the transverse incision in the flexor fold of the metatarsr)phalangeal joint the sej^a- ration will have been completed.

The dorsal tegumentary flap is then outlined and likewise dissected free. The metatarsal bones are sur- rounded totally by a circular incision, the muscles in the interosseous spaces divided, the periosteum of each bone individually pushed back at the place at which it is to be sawed through, and the saw finally applied from the dorsum of the foot to all of the bones simultaneously. *-*^2x Fig. 83.

Linear closure of the wound is finally effected. Ex articulation of the Little Toe, together with the Meta- tarsal Bone. — A lateral fla}) is formed according to the method of A\ alther. The oj^erator grasps the abducted little toe and a])plies the l)lade of the knife vertically in the interdigital fold between this and the adjacent toe, when the soft parts of the interspace are divided, by saw- ing movements of the knife held close to the metatarsal bone of the little toe, to the tarsus. From this point, with abduction of the toe and the metatarsus, entrance is gained into the joint between the fifth metatarsus and the cuboid bone, w^hen the toe is bent outward at the joint at a right angle or more. The operator incises the tissues around the tuberosity of the metatarsal bone close to the bone, and with sawing-movements detaches the soft parts from the outer side of the metatarsal bone until a flap has been secured of sufficient extent to cover the wound made. The flap is cut transversely from the wound outward. The little toe may also be exarticulated at the tarso- metatarsal joint by means of an oval incision, the apex of Avhicli is made upon the dorsum of the foot, as in removal of the great toe. The apex of the oval, as well as the longitudinal incision, may also be placed advantageously upon the lateral border of the toot. Removal of the Foot at the Tarsometatarsal Joint. Lis- franc's Operation. — It is important to determine the situa- tion of the ends of the line of the tarsometatarsal joint upon the inner and outer borders of the foot. The outer extremity corresponds with a point just behind the readily 140 OPERATIVE SURGERY. palpable tuberosity of the fifth metatarsal bone, Avhile the inner extremity is about a thumb's breadth in advance of the prominent tuberosity of the scaphoid bone. The line of the tarsometatarsal joint is not a directly transverse line between the two points named, but it pursues a com- plex course. From the fifth metatarsal bone it passes for- ward at an angle of 45° ; then it passes inward along the base of the fourth metatarsal bone. The next joint, be- tween the external cuneiform and the base of the meta- tarsal bone of the middle toe, is directly transverse, but projects somewhat forward. The articulation between the metatarsal bone of the second toe and the middle cunei- form bone is also transverse, somewhat behind that of the third metatarsal bone and in the line of that between the fourth metatarsal and the cuboid bone. The internal cuneiform bone projects forward (Figs. 84 and 85). Steps of the Operation. — The principle of the operation consists in dorsal opening of the joint and the formation of a musculotegumentary flap from the sole by an incision from within the wound outward. The operator stands at the periphery of the foot to be amputated, which he grasps from the sole, and with thumb and middle finger he marks the extremities of Lisfranc's articular line. Then an in- cision through skin and fascia is made on either margin of the foot do^vn to the muscles between these two points — a thumb's breadth in advance of the scaphoid tuberosity on the inner side and just behind the tuberosity of the fifth metatarsal bone — on the outer side and carried for- ward beyond the heads of the metatarsal bones. An incision convex anteriorly over the dorsum of the foot then unites the posterior extremities of these lateral in- cisions. After division of the skin and the subcutaneous connective tissue the dorsal flap is somewhat retracted. At the point of retraction the tendons and muscles of the dorsum of the foot are divided accurately in the direction of the cutaneous incision. There are thus exposed upon the dorsum of the foot the bones and the ligaments of the joints throughout a small extent.

The opening; of the joints is always Ix'gnn at the external border, at the artienlation hetMcen the fifth metatarsal bone and the lateral facet of the enboid bone, as this can always be readily found if the knife is introduced behind the prominence of the fifth metatarsal bone and the incision is directed obliquely for- ward and inward. According to Bergmann, tins joint coincides with the direction of a line passing from the tuberosity of the fifth metatarsal bone to the head of the first metatarsal bone. After this first joint has been opened the course of the remainder of the complex articu- lar line can be made out from the landmarks mentioned. The operator therefore directs his knife more toward the middle line of the foot and opens the almost transverse joint between the cuboid bone and the fourth metatarsal. The next also transverse joint is situated somewhat further forward. The transverse line of the joint between the second metatarsal bone and the middle cuneiform bone is readily found, corresponding with a prolongation inward of the articular line of the fourth metatarsal bone (Fig. 85). The joint between the first metatarsal bone and the in- ternal cuneiform bone also is situated further forward. The articular surfaces must be exposed by short incisions directed against the bone. The longitudinal articular surfaces are likewise exposed, and with increasing plantar flexion of the foot the short ligaments that unite the bones in the depth, as well as the ligaments of the sole, in so far as these fall within the range of the incision, are divided, until the whole series of joints is opened to a maximum degree. It is now still necessary to form a plantar flap. This must be so constituted as to include at its base the soft parts of the entire sole. The substance of the flap gradually diminishes in amount toward its periphery, so that at its extremity it consists only of skin and subcutaneous connective and fatty tissue, and it is thus readily united with the delicate skin of the dorsum of the foot (Fig. 87). With a long knife an incision is 10 146 OPERATIVE SURGERY. made horizontally through the sole around the sesamoid bones at the head of the metatarsal bone of the great toe, the knife being brought out of the wound transversely beyond the head of the metatarsal bone (Fig. 88). The Fig. 88. — Form and extent of the plantar flap in Lisfranc's operation. dorsalis pedis and the internal plantar artery are to be ligated in the stump. The stump left by Lisfranc's operation yields good functional results. The flap is firm and well padded, and the cicatrix lies upon the dorsal aspect quite out of the area of the walking-surface. The extensors of the ankle- joint (tibialis anticus, peroneus brevis), important as antag- onists of the triceps, are maintained in their attachments. Intertarsal Amputation. — The joint between the anterior surface of the scaphoid bone and the three cuneiform bones is opened, and the cuboid bone is sawed through transversely in the lateral prolongation of the joint named. The cutaneous incisions are the same as in Lisfranc's operation. The joint in front of the scaphoid bone, recog- nizable by its articular surface with three facets, is opened from the dorsum of the foot and made to gape widely. The periosteum upon the dorsal surface of the cuboid bone is incised transversely and the bone divided accord- ingly with the phalangeal saw. The bone is held in plantar flexion and the jilantar flap is made as in Lis- franc's operation. AMPUTATIOXS ASD EXUCLEATIOyS.

AMPUTATIONS AND ENUCLEATIONS. 149 Intertarsal Exarticulation. Chopart's Operation. — The a.stra<»al()S('aj)hni(l articulation upon the one liainl and the eal('an('o<'ul)oi(l articuhition upon the other liand constitute approximately a transverse line in ^vhich the foot may be (livi(hMl within the tarsus. The extremity of tliis articu- lar line upon the inner l)order of the foot lies just hehind the tuberosity of the scaphoid bone ; while upon the outer side the calcaneocuboid iirticulation will be entered if the incision is made a thumb's breadth behind the tuberosity of the fifth metatarsal bone. Chopart's joint is not repre- sented by a directly transverse line between these two points, but is curved somewhat as follows : the head of the astragalus is directed with its convexity forward, while the anterior articular surface of the os calcis is on the contrary excavated (Fig. 89). The calcaneoscaphoid interosseous ligament maintains the bones in apposition after division of the articular capsule. The operator occupies the same position as in Lisfranc's operation and lateral incisions are made along the borders of the foot outlining the plantar flap, the posterior ex- tremities of which are united by an incision passing trans- versely over the dorsum of the foot. The joint between the head of the astragalus and the scaphoid bone- is always opened first. It is not to be mistaken, as its situ- ation is indicated by the prominent head of the astragalus, in advance of which the incision is made, as ^yell as by the tuberosity of the scaphoid bone, behind which the incision passes. In order to divide the calcaneoscaphoid interosseous ligament and to open the calcaneocuboid articulation, the point of the knife is inserted in the outer extremity of the already opened astragaloscaphoid articu- lation, and the blade is directed toward the middle of the small toe, and the tensely stretched ligament is divided with a slight degree of pressure. The foot is flexed in the line of the o])en joint; the ligaments of the sole of the foot are divided in the line of the incision, and the plantar flap is made similar to that in Lisfranc's opera- tion, though correspondingly smaller, a finger's breadth 150 OPERATIVE SURGERY. behind the head of the metatarsal bone. In the stamp the dorsalis pedis and the internal and external plantar arteries will require ligation. If the directions given be not strictly followed, it is possible that instead of entering the astragalocuboid joint the operator may enter that between the anterior surface of the scaphoid and the three cuneiform bones. The retention of the scaphoid bone would scarcely be a dis- advantage, inasmuch as the posterior tibial muscle is Fig. 90. — Subastragaloid enucleation of the foot : tegumentary incision. attached to it. Jobert has recommended this method of prescaphoid enucleation as a regular procedure. The stump left by Chopart's exarticulation has a ten- dency to fix itself in a position of club-foot. This defect, it is thought, can be overcome by certain modifications, such as Jobert's prescaphoid exarticulatiou, as well as intertarsal amputation, inasmuch as the attachment of the tibialis anticus muscle to the scaphoid bone is pre- served and dorsal flexion is rendered possible.

In the original ope- ration the incisions were like those in Syme's operation, altliough the dorsal tegumentary flap extended beyond Chopart's joint. The foot was removed at this joint, and then the os calcis was extirpated. The best incision for amputation of the foot at the calcaneo-astragaloid and 152 OPERATIVE SURGERY. astragaloscaphoid joints is that of Giinther, who em- ploys an internal flap extending to the sole to cover the wound. The incision (Fig. 90) begins over the tuberosity of the OS calcis in the middle line of the heel, passes thence in Fig. 92. — Stumji following Malgaigne's operation. an arched direction below the external malleolus, and turns at the level of Chopart's joint toAvard the median line, to continue transversely across the dorsum of the foot to its inner border, whence it courses over the sole of the foot to the middle line.

The incision every- w luTe reaches down to the bone. The articuhition between the liead of the astragahis and the scaphoid bone is first opened, and then the eon- n(H'tions between the astrac^ahis and the os calcis are divided in the tarsal sinus. If the under surface of tlie astragahis is thus freecl, the flap outlined is separated Fig. 93. — Enucleation at the knee-joint: outline of the flaps. close to the bone from the inner surface of the os ealeis, while the foot is rotated outward upon its longitudinal axis (Fig. 91). In opening the joint between the head of the astragalus and the concavity of the scaphoid bone the calcaneocuboid articulation should not be included within the range of the incision. The articulation between the trochlear surface of the astragalus and the bones of the leg should also be protected. Exarticulation of the Leg at the Knee-joint. — An anterior 154 OPERATIVE SURGERY. tegumentary flap is made upon the extensor aspect of the leg, and the joint opened from this surface. A short mus- culotegumentarv flap is formed upon the flexor aspect by an incision from the wound outward. The teo-umentarv flap has a broad h'ASQ, and its lower extremity extends below the tuberosity of the tibia. The operator stands at the periphery of the member. The anterior flap is outlined by incision with the knife. The incisions, passing vertically downward from the most prominent points of the external and internal condyles of the femur, extend three or four fingers' breadth below the tuberosity of the tibia, at which level they are united by a transverse incision. The corners of the flap thus formed are rounded. The flap is now dissected from the subja- cent structures to the level of the patellar ligament. \Yith the extremity flexed at the knee the operator grasps the leg with his left hand, divides the patellar ligament with a single transverse incision, and enters the joint. The lateral ligaments and the crucial ligaments of the knee- joint are next divided, so that the leg is attached to the thigh by only the posterior wall of the capsule of the joint and the soft parts of the popliteal space. A long knife is introduced into the wound behind the tibia, and its edge is directed toward the periphery of the extremity, avoid- ing the head of the fibula, a short musculotegumentary flap being formed from the soft parts of the flexor aspect by incision from within outward. By these means the popliteal artery is not divided till the last stage of the operation. The patella remains connected Avith the ante- rior flap. Pollosson recommends that the operation be so performed that the cap- sule of the joint is opened close to the tibia in order that after separation of this bone the capsule may be again closed by suture. In this way a cavity is formed above the stump. Recovery is said to take place promptly and the stump is believed to gain in usefulness. Amputation of the Thigh. — Among methods of ampu- tation of the thigh that may be employed advantageously are : the circular incision in two steps, with the formation AMPl'TATIONS AND ENUCLEATIONS. 155 of a ciilV; and ol' ilap-incisions an ant( ri<»i- and a posterior niiiscnlott'iiuniciitarv flap of (Mpial si/c, or a lon^- anterior and a short posterior niusenloteguincntary Hap. Anqjutiitioii of the Thi(//i bi/ Matnn of a Circuhir Inci- sion in Two tStrps. — The pelvis of the subject is brought to the edge of the tal)h'. In amputating tli(^ riglit thigli the operator stands upon tlie outer si(U' ; and in amputa- tion of the left thigh, upon the inner side of the extremity, Avhieh is lieUl securely in a horizontal position. At a suf- ficient distance toward the periphery from the point at which the bone is to be divided a circular incision is made through the skin down to the fascia, and a cuff turned back. At the point of reflection of this cuff the muscles are divided down to the bone in four steps A\ith vigorous strokes of a long knife. The bone is divided with the saw at a point somewhat proximal to the incisions through the muscles. For this purpose the operator with the index- finger and thumb of his left hand pushes back the mus- cles upon the bone and divides the latter somewhat fur- ther from the periphery. The periosteum in the path of the incision is detached from the bone by means of a raspa- tory in the area to be saw'ed through, and the bone is di- vided with a saw, while the muscles are retracted by means of either tenacula or a divided bandage. In the center of the stump (Plate 9) may be seen the transverse section of the femur, around which the muscles are so grouped that upon the anterior surface lies the quadriceps femoris, while u})on the posterior surface lie the flexors. To the inner side the group of adductors lie wedged between the flexors and the extensors. The depression between the adductors and the extensors is covered by the sartorius muscle. In the space enclosed by these muscles, which is triangular in cross-section, are to be found the femoral artery and vein, as well as the saphenous nerve. Between the flexors is the sciatic nerve, always accompanied by vessels. In" the connective-tissue interstices of the mus- cles are small arterial vessels divided transversely or visi- ble in longitudinal sections. After control of hemorrhage 156 OPERATIVE SURGERY.

Osteoplastic Supracondylar Amputation of the Thigh by the Method of Gritty. — Gritty has ingeniously applied the osteoplastic principle of PirogoflPs operation to amputa- tions at the knee-joint, the freshened surface of the patella being approximated to the sawed surface of the femur, and union taking place. 3Iocle of Procedure. — An anterior flap is made as for exarticulation of the leg. This is dissected free to the level of the patellar ligament and the joint is opened transversely in this situation. At the same time the lateral attachments of the capsule attached to the con- dyles of the femur are divided so that the flap, with the patella contained within it, can be reflected. The patella is surrounded by an incision on the synovial surface of the flap, and freshened by removal of its cartilaginous articular surface with the phalangeal saw (Fig. 96). The flap is now somewhat retracted, so that the supracondylar portion of the femur is exposed. An incision is made around the bone in this situation, the bone is sawed through, and a short tegumentary flap is formed from the soft parts of the popliteal space by an incision from within outward. The patella is approximated to the sawed surface of the femur and fixed in this situation by bone-sutures or percutaneous pegs. The stump (Fig. 98) yields a functionally good result by reason of closure 11 162 OPERA TIVE S UR GER Y. of the medullary cavity of the femur Avith l^one and the favorable situation of the cicatrix. Ssabanajeif has modified the method of amputating the leg at the knee by bringing a segment of the tibia in ap- proximation with the sawed extremity of the femur, and the results are said to be superior to those of Gritty 's operation. An incision is made through the skin on the anterior aspect of the leg, as in Gritty's operation. A Fig. 99. — The •wound made in SsabanajeflTs operation : T, sawed seg- ment of the tibia for approximation to the femur ; F, sawed surface of the femur. short flap is outlined in the popliteal space with an arched incision and dis.sected free, the knee-joint being opened from the popliteal space. The leg is so bent at the knee- joint that the .surface of the tibia is brought in apposition with the anterior aspect of the thigh. From the articular surface a transverse plate of bone is removed from the upper extremity of the tibia as low down as its tuberosity, and this remains connected with the anterior flap. The thigh is further divided transverselv throuo-h its condvles. AMPUTATIOXS AXD EXVCLEATIOyS. 163 The sup|x>rting surface of the stump is thus formed by the tuberosity of the tibia, and clinical rejKnis are in accord in the statement that it s^^rves this puqx)se ad- mirably (Figs. 95 and W). Exarticulation of the Pemur at the Hip-joint by the Method of Esmarch. — The CMmbinatiun of circular ampu- tatiuii of the thigh with a luugitudinal incision (Esmarch) permits the removal of Jthe femur with a minimum loss of blood. The pelvis of the subject extends beyond the border of the table and the operator stands as in the per- formance of amputation. After the application of an Esmarch bandage as close to the tnmk as possible a cir- cular incision is made through the skin down to the muscles in the upper third of the thigh. At the point of retraction of the skin the muscles are divide-d typically in a circular manner down to the bone. The periosteum is likewise incised and the bone is sawed through. The next step consists in thorough ligation of the vessels in the trans- verse incision. After the lumen of all the visible vessels is closed by ligature the bandage is removed. Then a longitudinal incision is made upon the lateral aspect of the thigh, |xissing over the great trochanter, dividing the soft parts down to the bone, and extending to the level of the wound (Fig. 100). Hooks are introduced into the margins of the incision and the bone is freed fix)m its attachments. When the separation has been effected throughout a sufficient extent, the operator grasps the bone with his left hand, opens the joint, dislocates the head of the femiu*, and severs the round ligament, Avhen the central portion of the femur can be removed. The whole operation can be performeerformance of enucleation, witli the formation of two larr/e musculotegumentary jlaps by trans- tixion, renders possible rapidity of exarticulation, although the control of hemorrhage is difficult.

The outline of the Hap is always first carefully made with a knife ; the flap is then dissected free from the sub- jacent tissues, and the joint is opened from the extensor aspect. The flaps should be so situated that their bases correspond with the line of the articulation at which re- moval is to be effected. In making an ovalincision the operator applies the knife upon the extensor aspect somewhat to the proximal side of the line of the articulation and divides the tissues in the middle line parallel with the longitudinal direction of the finger until the joint has been passed. On the distal side of the joint the incision turns toward the right to run transversely through the flexor fold of the joint and it returns upon the opposite side of the finger, to termi- nate at its point of origin (Fig. 102). By detaching the tissues on either side of the oval from the subjacent struct- ures the joint is exposed upon its extensor aspect and the removal of the finger can be readily effected. Hemor- rhage will be controlled by ligation of the digital arteries, which run on either side near the palmar surface. The wound left after oval incision is closed in a linear direction. For enucleation of the thumb at the carpometacarpal joint an oval incision is best suited. The apex of the oval is situated upon the extensor aspect of the thumb at a point corresponding to that at which removal is to be effected. At the metacarpophalangeal joint the incision deviates toward the flexor aspect, passing transversely through the flexor fold of this joint and ascends upon the opposite side of the finger to join the longitudinal incision at an acute angle (Fig. 101). The incisions extend throughout down to the bone, from which the soft parts of the thenar eminence are carefully dissected. After the metacarpal bone has been freed the joint between the trapezium and the base of the metacarpal bone of the 174 OPERATIVE SURGERY. thumb is opened from the dorsal aspect and the finger is separated. Exarticulation of the little finger togetlier icith its meta- carpal hone by means of a flap from the integument of the ulnar border by the method of ^^'alther. The fourth and fifth fingers are extended and held in a position of maximum abduction. AVith the dorsum of the hand directed toward the operator, the blade of the knife is introduced at the middle of the commissure between the fourth and fifth fingers and passed with sawing-move- ments through the soft parts of the interosseous space between the fourth and fifth metacarpal bones to the root of the hand. With the point of the knife, now directed toward the radial border, the ligaments uniting the bases of the two metacarpal bones are first divided, while the little finger is held in a position of marked abduction, after which, by traction in the direction of abduction, the finger can be bent outward in the joint between the unciform bone and the metacarpus. The operator noAv surrounds the base of the metacarpal bone and forms a flap from the soft parts of the hypothenar eminence by incision from within outward (Fig. 103). Often the flap is cut too short. The operation may also be performed with the aid of an oval incision. The apex of the oval, as well as its longitudinal incision, may be situated either upon the dorsal aspect or upon the ulnar border of the metacari:)us. Amputation of one finger through the metacarpus is effected, like amputation of a toe through the metatarsus, through an oval incision. The apex of the oval is placed upon the dorsal aspect at a point corresponding to the site of amputation. The longitudinal incision passes along the metacarpal bone somewhat beyond the metacarpo- phalangeal joint, where it encircles the finger through the flexor fold, to ascend on the opposite side and meet the longitudinal incision. The muscles are detached from the metacarpal l^one, which is divided with the phalangeal or the arched saw. The peripheral extremity of the bone is enucleated and removed (Fig. 63).

Resections at the Joints of the Extremities. By resection of a joint is understood the systematic removal of its constituent parts, with conservation of contiguous structures. In the presence of tuberculous disease, as well as of severe injuries about the large joints, resection promised to be a conservative substitute for amputation. It can thus be realized that this mode of procedure Avas expected to prove a great advance in surgery, in times of both "war and peace. The methods of operation were so selected that compensation for the loss of the parts removed could reasonably be hoped for. AVith this thought Langenbeck devised operations for all of the joints in which the capsule was permitted to retain its connection with the periosteum, for whose osteoplastic capability experimental proof had been furnished (sub- periosteal resection). Langenbeck's incisions are still largely used in the performance of resections. The intro- duction of asepsis, as well as a more precise knowledge concerning the nature and the distribution of the tubercu- lous process in joints, has changed our views of these operations fundamentally. Antisepsis has rendered pos- sible conservative treatment Avith success of injuries to joints, even without resection, for which previously amputation would have been undertaken. The nature of the tuberculous process and the extent of its distribution in the joints, further, make it undesirable to adopt the routine plan of procedure in every case of removing the bones entering into the constitution of the joint, while the capsule as such is permitted to remain. Resection of tuberculous joints is no longer regarded as a typical pro- cedure to be employed in every case, as, for instance, is the extirpation of tumors ; nevertheless, opening of the joints of the dead subject in a typical manner is practised, as by this means the surgeon familiarizes himself with methods by which it is possible to o])en the joints with great care, and which render accessible throughout their whole extent 192 OPERATIVE SURGERY, the parts that enter into the formation of the joint, as well as the synovial surfaces of the capsule. Thus, in a certain sense, the preliminary operation is performed, with which clinically in the individual case the special operation of removal of tuberculous disease is conjoined. The capsule of the joint is widely opened [cuihrotomy), the synovial sac freed throughout its w^hole extent, and in accordance with the extent of the morbid process the extirpation of the synovia (^synovial artJrrecfomy), excochleation of areas of bone, possibly after exposure by means of the chisel and mallet, or resection of the articular extremities (os- seous arthredomy) is undertaken. When the disease is ad- vanced the bones are sawed through. In some joints division of one of the bones entering into the articulation w^ith a saw must be undertaken in order that the joint may be made accessible throughout its whole extent for the effectuation of the necessary operative measures. Indications : 1. Injuries, complicated destruction of the constituents of the joint, especially if large portions of bone are com- pletely severed from their attachments. 2. Tuberculosis of joints, if conservative measures (rest and fixation of the joint, treatment with iodoform, blood- stasis, minor local measures) have failed. 3. Deformities of the joints. Orthopedic resections for the correction of severe, otherwise irreparable alterations in form (contractures, ankyloses). 4. Luxaiions, if irreducible and attended Avith marked limitation of function. 5. Acute infiammatory processes in bones, osteomyelitis with epiphyseal separation and suppuration of the affected joint. 6. Flail-joints which it is desired toankylose artificially (arthrodesis). The incisions are made with short, strong knives, through the soft parts, down to the bone. After division of the capsule this, together with the periosteum, is sep- arated from its attachment to the bone and the latter is RESECTIOXS AT JOIXTS OF THE EXTREMITIES. 193 divided with tlio saw. The ineisions tliroiigh the soft parts are so arranged that transverse division, espeeially of muscles, tendons, large nerves and vessels, is so far as possible avoided. Langenheck's incisions for resection correspond mostly with the longitudinal axis of the ex- tremities. The articular capsule is opened as freely as possible in the direction of the cutaneous incision. The margins of the wound in the capsule being separated widely by means of tenacula, the operator ])egins, by means of a series of closely approximated incisions with a resection-knife, which is always applied vertically upon the bone, to separate the attachments of the capsule to- gether with the periosteum. The bones are forced out of the wound and divided by means of the arched saw, the metacarpal saw, or the wire saw, or the chain-saw. The plane of the sawed surface varies with the individual joints. For the correction of angular contractures wedge-shaped excision of bones is necessary. In place of this, arch- shaped resection (Helferich) may be employed, in con- junction with which the shortening is slighter. After resection of the bone has been effected the sawed surfaces are brought in apposition and fixed by means of nails or clamps, or even without these in a bandage. The division of the capsule, of the muscles, and of the skin is closed by sutures. By the introduction of drainage- tubes or of capillary drains escape of possible secretion is ])rovided for. Resections of the Joints of the Upper Extrem- ity. — Resection of the Shoulder-joint by the Method of Langenbeck. — The patient is placed upon the operating- table in a sitting posture in such a manner that the shoulder projects somewhat beyond the border of the table. The operator stands upon the side of the trunk, with his face directed toward the shoulder. He grasps the upper arm at its middle with the left hand and with the arm hanging naturally he enters the resection-knife held almost vertically into the coraco-acromial trigone 13 194 OPERATIVE SURGERY. (Fig. 11). The incision is made in the lonofitudinal axis of the arm through the deltoid muscle almost to its inser- tion into the humerus and down to the capsule (Fig. 118).

Witli the aid of a liook introduced into the slit in the capsule the latter is elevated and dissected free from the humerus close to the bone. The operator progresses step by stepj while the arm is rotated toward the knife. After the capsule has been divided through- out half of its circumference the remainder is similarly detached from the bone, tlie operator proceeding from the original slit in the capsule in the oj)posite direction. In connection with the capsule, into whose formation enter fibers of the shoulder-muscles (supraspinatus, infraspina- tus, subscapularis), the latter are at the same time de- tached from the bone at their insertion. ^Vhen the head of the bone has been thus freed it is lifted out of the Avound (Fig. 119), and divided at the level of the surgical neck of the humerus by means of the chain-saw, or, after being fixed with Langenbeck's forceps, with the arched saw (Fig. 120). The tendon of the biceps muscle is by this procedure preserved intact. After removal of the head of the humerus the glenoid cavity, as well as the whole interior of the capsule, is sufficiently exposed for whatever further operative procedures may be necessary. Vessels of considerable size are not injured in per- forming resection of the shoulder through a longitudinal incision. Resection of the Elbow-joint through a Dorsal Longi- tudinal Incision. — The arm is flexed at a right angle at the elbow-joint and thrown over the thorax in such a manner that the extensor aspect of the joint is turned up- ward. The operator stands upon the side of the thorax that corresponds witli the healthy member. The incision is made upon the doi^al aspect of the joint through the lower extremity of the triceps muscle over the olecranon (Fig. 122). Langenbeck makes this longitudinal incision rather nearer the inner border, while C'hassaignac makes it upon the outer border of the olecranon, although it may also be made satisfactorily in the middle line (Park). The incision passes through the triceps muscle down to 200 OPERATIVE SURGERY. the bone. While the lips of the Avoiind in the mnscle are energetically separated by means of hooks, the posterior wall of the capsule of the elbow-joint bulges into view and is divided in the direction of the cutaneous incision. With strokes of the knife directed vertically toward the bone the tendon of tlie triceps is detached from the olec- ranon close to the bone. At the same time the muscles Fig. 121.— Eesection of the elbow-joiut: exposure of the elbow-joint on its inner aspect ; the olecranon and the inner extremity of the troch- lea come into view ; the ulnar nerve has slipped from the inner epicon- dyle after retraction of the margin of the wound. inserted upon the dorsal aspect of the upper extremity of the ulna are detached in conjunction with the periosteum. Upon the outer side the radial head of the humerus and the head of the radius come into view, and the strong fibrous lateral ligament is to be freed close to the bone. On the inner side the detachment of the tendon of the triceps from the olecranon is begun.

If the margins of the wound are separated at its depth, the fibrous capsule of the joint becomes visible. Over the highest prominence of the liead of the femur the capsule is divided by an arched incision corresponding with the cutaneous incision. The articular cartilai>:e is incised and after division of the ligamentum teres the head of the femur is luxated upon the ilium and removed. Fig. 128. — Eesection of the hip: external arched incision by the method of Velpeau. If the removal of the head is to be effected at a higher point between the trochanters, or on the shaft of the femur, the tendons inserted into the trochanters must be detached from the bone with the knife. After the head of the bone has been sa^ved off the acetabulum is exposed for such further surgical interference as may be necessary.

The sawed surfaces of the bones are approximated and fixed in apposition by means of sutures, clamps, or \)v^s. According to the method of Volkmann, the anterior transverse incision passes from one condyle to the other over the middle of the patella. The periosteum is in- cised transversely and the patella is sawed through on a line with the cutaneous incision. In the prolongation of the incision through the patella the capsule is incised to the right and the left and the joint is widely opened. The knee is now strongly flexed at an acute angle, so that the incision into the joint is made to gape widely and the lateral ligaments, as well as the lateral attachments of the capsule, are divided. The crucial ligaments are divided from behind forward. The upper segment of the patella is reflected by traction, and the interior of th(^ capsule becomes accessible. The lower extremity of the femur is surrounded by a circular incision, grasped with forceps at the inner condyle, and divided transversely with a saw. In Hahu's modification the transverse incision passes above the pa- tella (Fig. 131). Kocher recorameuds a lateral hooked incision for arthrotomy and resection of the knee-joint. The incision begins at the vastus externus muscle, a hand's breadth above the patella, two fingers' breadth from whose outer border it passes downward, to terminate upon the inner aspect of the tibia below its spine. The articular capsule is divided on its outer aspect and the patellar ligament removed out of the way by separation of the spine of the tibia. The patella with its ligament is made so mov- able that it can be reflected inward. Division of the crucial ligaments permits a satisfactory view of the joint when placed in a position of flexion. Adequate access to the joint is had also for the performance of resection of the articular elements. Resection of the Ankle-joint. — Bilateral Longitudinal In- cision after Langenbcch. — The longitudinal incisions begin on either side, a hand's breadth above the malleoli, and pass along the tibia and fibula beyond their lower extremi- ties. The incisions pass through skin and periosteum. 212 OPERATIVE SURGERY. AVith the foot lying upon its inner border, the fibula is dissected free beneath the periosteum ^vith a knife or a raspatory on its outer and inner aspeets, and is divided in a linear direction above the malleoli with chisel and mallet or with the chain-saw. The peripheral fragment of the bone is reflected outward and separated from its attach- ments. In an analogous manner the lower extremity of the tibia is excised through the internal longitudinal in- FiG. 131. — Hahn's suprapatellar incision for resection of the knee-joint. cision. By the removal of the malleoli a view can be had of the interior of the joint, and the trochlear surface of the astragalus, as well as the walls of the cap.sule, is rendered accessible for further operative procedures. Lanofenbeck has obtained the most admirable results with this conservative method of resection following gun- shot-injuries of the ankle-joint, and especially transverse RESECTIONS AT JOINTS OF THE EXTREMITIES. 213 wounds Avith destruction of both malleoli. The operation is less well adapted for the modern j)roe('dure of arthrec- tomy, as the lower extremities of the libula and tibia are sacrificed, at any rate, and, besides, the opportunity for inspection of the joint afforded through the incisions is not adequate to meet the needs of extirpation of the capsule.

It passes over the body and neck of the astragalus, to terminate at the inner border of the foot at a point corresponding with the tuberosity of the scaphoid bone. The outer incision runs parallel with the inner, along the anterior surface of the 214 OPERATIVE SURGERY. tibia, opens the joint at the malleolus, and terminates at the level of the astragaloscaphoid articulation (Fig. 132). The anterior bridge of skin, which contains the extensor tendons, the vessels, and the nerves, is dissected from the subjacent tissues, the insertion of the capsule being at the same time detached transversely from the trochlea of the as- tragalus and the border of the tibia, and if necessary the anterior portion of the synovial membrane is excised. By lifting up the bridge-like flap, with dorsal flexion of the foot, the individual portions of the joint may be made accessible to the eye and to instrumental manipulation. The removal of the astragalus is readily eflPected through the inner incision, when the articular surface of the tibia and the posterior wall of the capsule become visible. Reverdin-Kocher 3Iethod of Luxation through an Ex- ternal Transverse Arched Incision. — The incision begins at the tendo Achillis about a hand's breadth above the malleolus, passing downward, surrounding the external malleolus, and terminates on the outer border of the foot along the outer margin of the extensor tendons (Fig. 133). After division of the skin and exposure of the external malleolus the accessory ligaments of the capsule inserted in this situation are divided. The attachment of the capsule is freed, with displacement of the extensor ten- dons, and, if necessary, division of the peroneal tendons upon the anterior and posterior aspects of the tibia, when the foot is flexed upward in such a manner over the in- ternal malleolus that its inner border is brought in contact with the inner aspect of the tibia (Figs. 134 and 135). The joint is thus made accessible to inspection, and neces- sarv operative procedures upon the articular extremities, as well as upon the capsule, may be undertaken. Resection of the Foot by the Method of Wladimiroff and Mikulicz. — Indications : (1) Caries of the foot localized in the calcaneum, the astragalus, and the astragalocrural articulation.

(5) Shortening of the extremity, following luxations of the liip-joint (Caselli) ; after resections of the knee-joint (Rydygier). (6) Paralytic club-foot (Bruns). The parts removed in the resection include the lower extremities of the tibia and the fibula, the astragalus, the calcaneum, and a portion of the cuboid and scaphoid bones in conjunction with the skin of the heel. The anterior portion of the foot is maintained in relation with the leg by means of a dorsal bridge containing the ten- dons and vessels. Mode of Procedure. — A transverse incision is made through the sole of the foot corresponding to the extremi- ties of Lisfranc's line, and a second transverse incision is made transversely above the malleoli on the posterior aspect of the leg ; the extremities of both being united by additional lateral incisions (Fig. 136). The astragalo- crural joint is opened from the dorsal aspect and stretched widely, and the bones of the leg are divided transversely above the malleoli. The root of the foot is grasped at the trochlea of the astragalus, and it is freed close to the bone from the dorsal soft parts, with maximum dorsal flexion of the foot. In accordance with the extent of tissue to be removed the tarsus is sawed through in the region of the cuboid and scaphoid bones, or further to the distal (at the base of the metatarsal bones) or to the proximal side. When the operation is performed for orthopedic reasons, only the lower extremities of the tibia and the fibula and the tuberosity of the calcaneum are removed, together with the trochlea of the astragalus. Inasmuch as after the resection has been effected the sawed surfaces of the bones of the leg and the tarsus are approximated and united by bone-suture, there results an artificial club-foot to such a degree that the dorsum of the foot lies in the same plane as the anterior aspect of the leg (Figs. 137 and 138). 218 OPERATIVE SURGERY. In performing tihiocalcaneal resection by the method of Bruns, the ankle-joint is opened through an arched dorsal incision, the astragalus freed, and the lower extremities of the tibia and the fibula, as well as the upper surface of the calcaneum, sawed through transversely, when the sawed surfaces are nailed together. Osteotomy. — Osteotomy consists in linear division by bloody means of the long bones. Originally performed through an open wound, the operation has since the time of Langenbeck been performed, like tenotomy, through a small incision in the skin, in a measure subcutaneously. The division of the bone is effected with the aid of sculp- tor's chisels. The extremity is placed upon a board or upon a sand- bag, the Esmarch apparatus is applied, and the operation of osteotomy is undertaken. A short incision through the soft structures penetrates down to the bone. AVith slight blows of the mallet the chisel is driven into the bone. After it has penetrated it is removed, and a similar pro- cess is gone through in a neighboring situation. In this manner the cortical structure of the bone is successively divided transversely throughout almost its entire circum- ference. The remainder is fractured by forcible bending, and the extremity, after the cutaneous wound has been properly united, is fixed in an appropriate position in a plaster-of-Paris dressing. In cases in which simple linear osteotomy will no longer suffice, wedge-shaped excisions are undertaken for the correction of ankylosis, or curvatures of high degree. The base of the wedge corresponds always with the con- vexity of the curvature to be corrected. After adequate exposure of the bone and division and detachment of the periosteum, the wedge is removed with the chisel or the saw, when the correction of the deformity may be readily eifected. A special form of osteotomy employed for the correc- tion of marked arcuate curvature of the long bones con- sists in longitudinal division, the bone being divided in a direction parallel with its long axis. The displacement RESECTIOSS AT JOiyTS OF THE EXTREMITIES. 219 Resection of the Foot by the Method of Wladimiroff- MlKULlCZ. Fig. 136. Cutaneous incisions. Fig. 137.

RESECTIONS AT JOINTS OF THE EXTREMITIES. 221 of the segments of bone in the axis of the part renders possible to a certain degree correction of deformity. Odcotomy of the femur at the upper extremity of the bone is undertaken in cases of contracture of the thigh, if the correction of the faulty position is attended with difficulty after division of the contractured soft parts. Linear osteotomy under these circumstances is undertaken either at the neck of the femur (osteotomia colli femoris), or at a point between the two trochanters (osteotomia intertro- chanterica). For the exposure of the upper extremity of the femur a longitudinal incision over the trochanter is made upon the postero-external aspect of the joint. In this situation the neck of the femur can be exposed for osteotomy, as well as a deeper portion of the bone after separation of the muscular attachments to the greater trochanter. Supracondylar osteotomy of the femur has been recom- mended by Macewen as a routine procedure in the treat- ment of genu valgum. According to Mace wen's recom- mendation, the short cutaneous incision on the inner aspect of the lower extremity of the femur is made at a point corresponding to the intersection of two lines, of which one passes a finger's breadth above the upper border of the external condyle, and the other in the longitudinal axis of the bone two fingers' breadth in advance of the tendon of the adductor magnus. At the point of inter- section of these two lines a short longitudinal incision is made down to the bone, the chisel introduced through the wound, applied transversely, and the cortical structure of the bone successively divided throughout two-thirds of its circumference. The remainder of the bone is severed by manual means. Supracondylar osteotomy of the femur may also be undertaken from the outer side of the bone in a corresponding situation. Linear osteotomy, as well as excision of wedge-shaped portions, may be undertaken upon the bones of the leg for the correction of deformities at the knee-joint, or of excessive curvature. The tibia is exposed at its upper 222 OPERATIVE SURGERY. extremity, from 4 to 6 cm. below the articular line, by means of a transverse incision around the inner circum- ference of the bone (Kocher). After detachment of the periosteum the bone is divided with the chisel in the direction of the cutaneous incision. Excision of a Avedge-shaped portion of the tibia may also be effected through the same incision. Tni:i'iiis'[NO. 223 II. OPERATIONS ON THE HEAD AND NECK.

The deficiency in the bone established either remains open or it is closed. Under the condition first named, the skin being utilized to cover the defect in the bone, the opening becomes closed by connective tissue, a result that is attended with certain disadvantao-es. It has therefore become the rule, whenever the nature of the case renders it permissible, to close the trephine-opening by means of bone. This may be effected : 1. By reimplantation of the piece of bone trephined ; 2. By autoplasty or heteroplasty ; 3. By temporary resection of the cranial bones, em- ployed from the outset as a substitute for typical tre- phining. The restored button of bone should at the present time, under aseptic conditions, heal in place in all cases ; but reimplantation has been successfully undertaken by Ph. v. Walther. Autoplasty, an ingenious procedure devised by Kdnig, consists in the transplantation upon the defect of a pedun- culated flap consisting of skin, periosteum*, and a portion of the cortical structure separated with a chisel. The defect resulting from the formation of the flap is covered with a pedunculated cutaneous flap removed from the ad- jacent region.

In the groove thus made the operator can determine with tlie aid of the probe when the vitreous plate has been passed. As soon as the plate of bone is freed throughout its eireumference it is raised with an elevator and removed from its place. The circular saw and the diisel may be advantageously used together, the boundary of the part to be removed being outlined with the saw, and the groove being deepened down to the dui*a with the chisel. By means of a trephine a Ijutton of bone is removed from the skull as large as the opening in the crown of the instrument. The crown is evenly and firmly applied upon the bone with its teeth while the head is fixed. After the teeth of the instrument have entered the bone the pressure and the rotation are continued in even, though slighter, degree. The groove made by the saw is frequently cleaned and examined as to its depth. As soon as the fragment of bone is loosened it is grasped with the tirefond, a gim- let-like instrument, and is removed.^ Bv means of a special knife, known as the lenticular, it was customary in the past to smooth the margins of the opening. The mode of procedure does not follow this typical course in cases of fracture of the skull. Completely separated splinters that have been forced into the brain are to be removed, depressed portions of bone are to be raised, and sharp margins are to be cut off, etc. For elevating and re- moving fragments of bone rongeur-forceps are employed ; for enlaro^incr fissures in bones the chisel and mallet are employed exclusively. Temporary resection qftheshuU (Wagner, ^Volif, Oilier) has of late almost entirely replaced the classic mode of trephining. AVagner incises the skin in the shape of a lyre or of an omega fi?-shaped) (Fig. 139), the incision passing down to the bone at all points. A furrow is cut 1 Instead of employing a special instrument to lift out the button, the bit of bone can be forced out by means of a periosteum-elevator or a blunt dissector used as a lever. — Ed. 228 OPERATIVE SURGERY. into the bone with the cireidar saw corresponding with the cutaneous incision, and the groove is gradually deepened by means of chisel and mallet until the dura is reached. At the base, corresponding with the narrowest portion of the flap, the bone is divided with a single stroke upon the chisel, when the flap of integument, periosteum, and bone can be reflected (Fig. 140). After the intracranial manipulation has been completed (opening of an abscess, resection of a cortical center, removal of a foreion bodv, ligation of the middle meningeal artery, etc.), the boue is replaced in the artificial opening and the cutaneous wound is closed by suture. To facilitate the localization of the anterior and posterior branches of the middle meningeal artery Steiner has suggested the following ana- tomic guides : a line is drawn from the middle of the glabella to the apex of the mastoid process. Upon the middle of this line another, verti- cal line is erected. Where the latter intersects a third line passing hori- zontally through the glabella the crown of the trephine is applied, and on removal of the button of bone the trunk of the anterior branch of the middle meningeal artery will be reached (Fig. 141). At the point where a vertical line passing in fi'ont of the mastoid pro- cess intersects the horizontal line already spoken of a trephine-opening "will reach the posterior branch of the middle meningeal artery. Since the introduction of temporary resection of the skull by means of the chisel, the making of a number of isolated trephine-openings for the exposure of the two branches of the middle meningeal artery is obviated. By the formation of a flap of suitable size, with its base above the malar bone (Krause'sflap for intracranial exposure of the Gasserian ganglion), it has become possible to expose the branches of the middle meningeal artery throughout a sufficient extent (Fig. 141). The length and width of the flap spoken of are about 6 cm. ; the former measured from the zygo- matic i^rocess, the latter a thumb's breadth external to the margin of the orbit. The upper extremity of the Rolandic fissure lies in an anteroposterior plane, 1.2 cm. behind tlie middle of a line uniting the root of the nose with the occipital protuber- ance.^ ^ In the making of an osteoplastic flap the bone can be sectioned with great neatness and considerable rapidity by the use of the Gigli wire-saw after the plan of Obalinski. Such a saw consists of rough steel wire with a loop at each end. The handles of a chain-saw tit the loops. Two or more small trephine-openings are made, the dura between the openings is separated from the skull, a piece of silk is carried from opening to opening by means of a probe, the saw is pulled through by means of the silk, the handles are attached, and the bone is sawed from within out- ward. — Ed.

The palatal process unites in the middle line with a similar process of the bone of the opposite side. The frontal or nasal pro- cess unites the upper jaw with tlie Irontal bone, and the zygomatic process unites it with the malar bone. The posterior surface of the body of the upper jaw is united with the descending wing of the sphenoid and with the 230 OPERATIVE SURGERY. ,r-r,4.--*^ pyramidal process of the palatine bone. These processes must all be severed if the upper jaw is to be separated from its attachments. Ste-ps of the Operation. — The head of the patient is placed on a lower level than the trunk. Preliminary tracheotomy and the introduction of a tampon-cannula are not necessary. The cutaneous incision (Weber) is immediately made at all points down to the bone. It begins at the middle of the upper lip, which it divides vertically ; after reaching the septum it surrounds the nasal ala on the side to be operated upon to its upper ex- tremity ; it then continues vertically upward to the inter- nal canthus of the eye, and thence at an acute angle it passes outward in a curved direction along the lower mar- gin of the orbit to end at the external canthus of the eye (Fig. 142). The flap thus formed from the soft tissues of the cheek is dissected from the upper jaw so that the canine fossa, as well as the malar process, is exposed.

In both instances, after completion of the operation, the divided halves of the jaw are reunited with metallic sutures. The cuta- neous wound is closed with knotted sutures. Reseetion of the Lower Jaw in its Continuity. — For the removal of portions of the lower jaw in its continuity the cutaneous incision is made down to the bone at its mar- gin. The soft tissues are detached from the outer and inner surfaces of the jaw, until the mucous membrane of the lips, as well as that of the floor of the mouth, is divided close to the bone. At the two points through which the jaw is to be salved a tooth is withdra^vn, and the segment of bone of determined size is removed with RESECTIONS OF THE J A WS 241 Fig. 147. — Median temporary division of the lower jaw by the method of Sedillot. 16 OPERA no Xa ox rilK TOXGUE. 243 the chain-saw.

Alter resection of the middle portion the stumps of the genioglossus muscles, separated from the chin, must be fixed -in the cntaneous wound by sutnre, so that the tongue thus deprived of its attachment to the chin does not fall backward, a contingency not unattended with danger. Operations on the Tongue. — Extirpation of tumors of the tongue are atypical })rocedures that are not carried ont according to generally applicable rules. It is of the greatest importance that the removal of the tumor be effected through healthy tissue, and that the wound-tlefect be so made that union through suture or closure of the wound with healthy tongue-substance is possible. The preliminary operations performed for the pui-pose of facilitating total extirpation of the tongue and rendering the floor of the mouth more convenient of access have already been considered in part (temporary resection of the lower jaw). In performing operations upon the tongue the patient is placed upon the table with the upper part of the body elevated. The neck is stretched and the head is fixed in this position. The mouth is held open with a suitable speculum or gag. The tongue is grasped with a strong silk ligature passed through its structure and drawn forward. Circumscribed tumors at the margin of the tongue are excised in the form of a wedge through the mouth from healthy tissue with the scalpel or with scissors. The wound can be closed by linear approximation through deep and superficial sutures. In advance of extirpation of half or the whole of the tongue ligation of the lingual artery upon one or both sides is undertaken to prevent hemorrhage. If the extirpation is to be effected through the poste- 244 OPERATIVE SURGERY. Plate 12.— Lateral Temporary Division of the Ramus of the Jaw by the Method of Langenbeck.

OPERATIONS ON THE TONGUE. 251 Division of the cheek in a horizontal direction from the angle of tlic inoiitli renders tlie operation more convenient, inasmuch as tlie Held of operation is made roomier, and it can also be better illuminated. After the operation on the tongue has been completed the incision in the cheek can be united by suture. Suh)ncntal removal of the tongue^ first performed by Regnoli of Pisa, is effected through a semilunar incision made upon the neck along the ramus of the lower jaw. Regnoli conjoined with this arched incision a second, vertical incision passing from the chin to the middle of the hyoid bone. Billroth made only the simple arched incision. Access is gained to the inner side of the ramus of the jaw, the attachments of the mylohyoid muscle are separated laterally, and those of the genioglossus, genio- hyoid, and digastric muscles in the middle, and the mucous membrane of the buccal cavity is opened through- out the entire extent of the incision. The tip of the tongue is caught with a thread and drawn through the wound. By these means the structures of the floor of the mouth, as well as the tongue down to its base, are con- veniently accessible for operative attack (Fig. 149). Temporary resection of the lower jaw is effected in accordance with the rules laid down on page 234. The divided portions of the lower jaw are held apart by means of sharp hooks, in consequence of which the field of operation is rendered more extensive. The division of the lower jaw may be linear, or, to facilitate approxima- tion in suturing the bone, it may be made in steps. In the presence of extensive disease of the tongue Kocher effects extirpation of the organ from the base. He first performs preliminary tracheotomy. The cuta- neous incision passes from the mastoid process along the anterior border of the sternomastoid muscle to the level of the hyoid bone, and from this })oint, in the furrow between the floor of the mouth and the neck, forward, to end in the median line at the chin (Fig. 148). The flap thus outlined is reflected back, when, after ligation of 252 OPERATIVE SURGERY. the external maxillary and lingual arteries, the submaxil- lary glands are removed. The buccal cavity is opened through the mylohyoid muscle and the raucous membrane detached from the lower jaw. The tongue must yet be separated from the hyoid bone, after which the whole organ can be brought forward and divided through healthy structure. Plastic Operations. — Plastic operations include those accessory operations by means of which existing wound- defects are covered with integument, as well as such pro- cedures as are intended for the correction of congenital or acquired deformity. In the first category belongs, for instance, the formation of pedunculated flaps for the closure of defects left by wounds ; in the latter, operations for harelip, rhinoplasty, blepharoplasty, etc. In covering wound-defects the adjacent skin is drawn over either directly or after being freed by incisions and attached in place. In other cases flaps taken from neigh- boring structures must be separated from the subjacent tissues, and either displaced laterally or rotated about their base, in order that they may be brought in apposition with the defect, and fixed in place. A triangular defect that is not too large is covered directly by means of deep sutures parallel to the base, and linear union is thus eflFected. (Linear union after wedge-shaped excision of the lower lip is illustrated in Figs. 150 and 151.) If the defect be greater, rhomboid flaps symmetri- cally situated on either side may be drawn toward the middle line to cover the defect (Diefienbach, Figs, 15-2 and 153). In place of the rhom- boid flap an arched incision passing from the base of the defect on either side may outline a portion of adjacent skin, which is brought over the defect and attached in place. Quadrilateral or oval defects may be cov- ered by one or two symmetrically formed flaps from the immediate neighborhood (cheiloplasty by the method of Bruns,or by thatof Langeu- beck, Figs. 154 and 155). The flap is made to correspond in shape with that of the defect, though somewhat larger. These methods, in accordance with which the flaps are obtained from the immediate neighborhood of the defect, stand in contra- distinction with that in which a pedunculated flap belong- ing to a remote portion of the body remains attached in PLASTIC OPERATIOSS. 253 its orifrinal situation thmuirli tlic pofliclc until the flap has healed in the deteet (rhinoplasty by means of a flap re- moved from the arm, aceording to the method of Tag- liacozzi).

On the inner aspect of the ramus of the lower jaw it enters, with the arteiy of the same name, into the dental foramen and passes through the dental canal, to make its exit at the mental foramen as the mental nerve. The lingual nerve in the first part of its course passes downward with the dental nerve. At the anterior border (^f the internal pterygoid muscle it turns forward, and passing over the mylohyoid muscle reaches the lateral border of the tongue. Extrdhuccal Exposure of the Buccinator Xen'e (E. Zuckerkandl). — A cutaneous incision is made in the direc- tion of a line passing from the tragus to the middle of the nasolabial fold. The duct of Stenon apj)ears in the wound and is drawn downward. After division of the 270 OPERATIVE SURGERY. masseter fascia the buccal pad of fat comes into view, and is freed from its attachments and removed. In the wound there are now visible the coronoid process of the lower jaw, with the prominent lower portion of the tendon of the temporal muscle. At the inner border of this tendon, surrounded by loose cellular tissue, lies the trunk of the buccinator nerve. The inferior dental nerve may be exposed before its entrance into the dental canal, within the canal, and after its exit at the mental foramen. Prior to its entrance into the canal, at the lingula, the nerve is accessible from without (Sonnenburg-Lucker) as well as from Avithin the cavity of tlie mouth (Paravicini). Sonnenburg makes an incision around the angle of the lower jaw, separates the insertion of the internal pterygoid muscle from the bone, and advances along the inner surface of the ramus of the jaw to the lingula, where the nerve is gmsped Avith a blunt hook, brought out and resected, or extracted with forceps. This method is attended with difficulties in so far as it is necessary to operate at a considerable depth ; even operating upon the dependent head simplifies the procedure only in inconsiderable degree. Paravicini has recommended exposure of the nerve from the buccal cavity by separation of the internal pterygoid muscle from the inner surface of the ramus of the jaw at the lingula. Exposure of the Inferior Dental Nerve within the Dental Canal. — The nerve is most conveniently reached by chis- elling out a piece of the outer plate of the bone at the point of junction between the body and the ramus, and in this manner exposing the dental canal. An arch-shaped cutaneous incision is made at tlie angle of the jaw. The attachment of the masseter muscle is freed and separated from the bone in the neighborhood of the angle of the jaw by means of a raspatory. In the mid- dle of a line uniting the angle of the jaw with the last molar tooth a piece of bone as large as a lentil is gouged out of the outer wall of the jaw. After the cortical OPERATIONS ON NERVES. 271 striK'turo lias Ixni passed profuse arterial heniurrliage from the injured interior dental arterv will indieate that the eanal has been oi)ened. With a blunt hook the nerve can be readily raised from its bed, and it is either resected, or, better, it is extracted with forceps. The lingual nerve is most readily reached from tlie buccal cavitv. An incision is made uix>n the side of the tongue at the point of i-eflection of the mucous membrane from the inner side of the lower jaw upon the tongue. Fig. 175. — Exposure of the infra-orbital nerve. The large nerve-trunk lies immediately l)eneath the mucous membrane. The methods of Sonnenburg and Paravicini for exposure of the inferior dental nerve also permit access to the lingual nerve in its upper part. The mental nerve can be made accessible at its point of exit from the lower jaw, from either within or without the buccal cavity. Extrabuccal exposure is accomplished by means of a cutaneous incision through the chin at the level of, and several centimeters external to, the incisor 272 OPERATIVE SURGERY. tooth of the corresponding side. The incision reaches down to the bone, and the soft parts are detached from the jaw, when the nerve can be seen making its exit as a tense cord from the mental foramen. To gain access to the nerve from within the cavity of the mouth an analo- gous procedure is followed. The incision is made at the point of reflection of the mucous membrane from the r ./ Fig. 176. — Intrabuccal exposure of the mental nerve. inner surface of the lower lip upon the lower jaw^ (Fig. 176). Operation for Exposure of the Second and Third Divis- ions of the Fifth Nerve at the Base of the Skull by the Method of Krbnlein. — A semicircular flap, with its con- vexity downward, is formed from the tissues of the cheek, its base corresponding to the upper boundary of the zygo- matic arch. The cutaneous flap is dissected upward, the temporal fascia divided transversely over the malar bone, then the zygomatic arch sawed through in advance of the articular tubercle and through the body of the bone and, with the attachment of the masseter muscle, reflected OVKHATIONS ON NERVES. 273 downward. Tlic exposed coroiioid process oi' tlie lower jaw is hroUeii ihroiigli and, t()«!,'elljer with tlie tendon of the temporal niusi^h', is disphieed n])\\aie l)y means of a ln>ok inserted on either side, and if uecessarv the ligament is, further, notched. The cannula is intro- duced into the opening thus made and the h(^)oks are re- moved from the wound. By this mcxle of procedure there is no loss of blood and the cannula lies so snugly within the wound as to constitute a sort of tampon. If there be surticient time for the performance of the openition the cutaneous incision is made longer and the cricothyroid ligament is laid bare by careful dissection. After the subcutaneous connective tissue has been passed the cervi- cal fascia is divided and the cricothyroid lig-ament is ex- posed. The lower border of the cricoid cartilage is raised up by means of a simple sharp tenaculum, which is intro- duced inti^ the middle line, when the ligament is divided vertically and a cannula is introduced. If necessary, the longitudinal incision in the ligament is notched on the right and the left. Through the crucial incision thus formed the cannula is readily introduced. The latter is held in place in the wound by means of linen tapes attacheil to the shield of the cannula, and tied at the nape of the neck. Extirpation of the Larjmx. — If removal of the larynx is to be conjoine<:l with larvngotissure, to the longitudinal in- cision a transverse incision is added at the level of the hyoid bone, when, after division of the muscular attachments to the lower surface of the hyoid bone, the thyrohyoid mem- l)rane is divided in corresi>i^ndence with the superficial transverse incision. The soft parts on the outer side are to be separated close to the laryngeal cartilages. Ujxm the j)05terior aspei't the cricoid cartilage is freed from its loose attachment to the anterior wall of the esophagus. If the upper and lower boundaries of the larynx also have been incised upon the mucous surface, the larynx is completely freeil after transverse division of the trachea 278 OPERATIVE SURGERY. below the larynx. Tlie deficiency left in the anterior portion of the pharynx and esophagus is reduced to a niininiuni l)y suture. The cannula is left in the trachea. The wound remains open and is tamponed. Tracheotomy. — Tracheotomy consists in properly open- ing the trachea through incision. The procedure is in all cases attended with the introduction of a cannula through the opening into the trachea. Indications : (1) Injuries of the larynx (punctured, incised, and gun- shot-wounds, fractures of the laryngeal cartilages with dis- location of the fragments). (2) The presence of foreign bodies in the trachea which cannot be removed by endolaryngeal procedures. (3) Stenosis of the larynx and the trachea : (a) Compression-stenosis (goitrous tumors, aneurysms) ; (6) Occlusion-stenosis (obstruction of the lumen of the larynx or the trachea, swelling of the laryngeal mucous membrane — diffuse submucous laryngitis ; tuberculous, syphilitic, and typhoid disease of the larynx). Narrow- ing of the lumen of the larynx, or of the trachea, through exudates (diphtheric croup), through neoplasms (carci- noma, papilloma, granulation-tumors) ; (c) Cicatricial narrowing of the larynx (after healing of ulcerative processes ; after operative procedures upon the larynx. (4) As a preliminary operation, or in conjunction with other operations upon the larynx and the pharynx, trache- otomy is performed : {a) To prevent the entrance of blood into the bronchi (tampon-cannula) ; (6) Following operations upon the larynx, without leaving an opening or with closure by tampon, in order to supply the patient with air. (5) Asphyxia or intoxieation, to render possible and to institute artificial respiration. The trachea is the direct contmuation of the larynx, passing in the middle line of the neck toward the upper OPERATIONS ON THE AIR-PASSAGES. 279 npcM'tnrc of tlic tlioi-.tx.

The su})rastL'riial portion is separated from the skin, in addition to the two layers of cervical fascia, by a considerable layer of cellular tissue containing numerous veins. The thyroid gland overlies the trachea between the third and sixth cartilaginous rings ^vith its lateral lobes connected by the isthnuis. Often a pyramidal lobe of the thyroid gland covers also the upper portion of the trachea. The anterior surface of the trachea and of the thyroid gland is covered by the muscles passing from the sternum to the hyoid bone and the thyroid cartilage (sternohyoid, sternothyroid). In the middle line, between the muscles, a strip of trachea is covered only by the cervical fascia. It is through this " white line of the neck " that the trachea is attacked. The isthmus of the thyroid gland divides the trachea into two parts, a supra- thyroid and an infrathyroid. The opening through the former constitutes superior tracheotomy ; that through the latter, inferior tracheotomy. Superior Tracheotomy. — The patient lies in the dorsal decubitus, with the neck over-extended, and a cylindric pillow is placed beneath the shoulders. The operator stands upon the right side of the patient and his assistant upon the opposite side. The cutaneous incision is made accurately in the median line of the neck from the middle of the thyroid cartilage to below the thyroid gland. After the skin and the subcutaneous connective tissue have been passed the tense fascia of the neck is divided upon a grooved director. The inner borders of the sterno- hyoid nniscles come into view, and are retracted sym- metrically with blunt hooks. The situation of the trachea is determined by palpation with the finger, and its first cartilaginous ring is exposed by detaching the cellular tissues from the trachea by means of two pairs of ana- tomic forceps. The field of operation is extended through- out a sufficient extent by incising the layer of fascia stretched between the upper border of the thyroid gland 280 OPERATIVE SURGERY. Plate 14. — Inferior Tracheotomy. The wound is bounded laterally by the sternohyoid muscles. The trachea is exposed and opened upon its anterior aspect for the introduc- tion of the cannula.

Lying close to the right of the trachea in the depth of the wound is the innominate artery. and the trachea, and dislocating the gland downward by means of blunt hooks. Before proceeding with the open- ing of the trachea the upper rings must be thoroughly exposed by dissection. Then the trachea is grasped just below the cricoid cartilaginous ring accurately in iho middle line with a simple sharp tenaculum, raised some- what and held fixed in this position. The trachea is then incised accurately in the middle line from below upward for a distance of al^out 1 cm. with a sharp-pointed knife. The opening thus made is distended by means of shai'p tenacula and possibly nicked on either side. AVhile the three tenacula are held, undisturl)ed, in place, the ope- rator introduces the cannula into the trachea. The cuta- neous wound is reduced in size by knotted sutures and the cannula is firmly fixed in place by means of tapes. Inferior Tracheotomy. — The patient is placed in the same position as in the performance of superior trache- otomy and a cutaneous incision is made from the lower border of the thyroid gland to below the suprasternal fossa (Fig. 177, c). After the skin and the subcutaneous connective tissue have been penetrated the superficial layer of the cervical fascia is exposed and divided upon a grooved director in the direction of the cutaneous incision. A considerable layer of loose connective tissue is passed through by means of two pairs of anatomic forceps, while the inner border of the sternoliyoid muscle on either side is retracted. In the dense layer of connective tissue the middle thyroid veins pass vertically downward to the left innominate vein, and nuist be avoided or possibly ligated in two ])laces and divided between. During the progress of the blunt dissection the situation of the trachea, toward Tab. 14. Lith.

Before the traehea is reaelicd the deep layer of the cervical fascia is divided upon a grooved director. Only after this has been done is it possible to isolate the treaehea adecjuately. Before the lumen of the tube is opened the trachea is grasped with a simple sharp tenacu- X .• ,J Fig. 177. — Cutaneous incisions on the neck : a, infrahyoid pharyngot- omy ; b, cricothyrotomy ; c, inferior tracheotomy. lum and raised and fixed at the level of the skin.

The tracheal wound is held Avidely open by means of sharp tenacula, possibly incised to right, and left, when the introduction of the cannula is under- taken (Plate 14). After the cannula has been introduced into the trachea the tenacula are removed. The cannula is fixed by means of tapes and the cutaneous wound is reduced by suture. If the tracheotomy can be performed at leisure and under favorable conditions, the typical mode of procedure is unattended with difficulty. The reverse is the case, how- ever, if the operation must be undertaken in the presence of threatened danger to life or of severe dyspnea. Under these circumstances all of the presence of mind of the operator will bo required to maintain the mastery of the situation, which is often a critical one. The smallest veins of the neck are dilated and distended with blood. In the presence of conditions like these the cutaneous incision is enlarged, as by this means the isolation and lio:ation of the veins are considerablv facilitated. The thin walls of the distended veins are not readily recog- nizable. Veins that interfere with deep dissection are ligated in two places and divided between. At successive stages of the dissection the position of the trachea is con- stantly kept in mind. Neglect of this ])recaution may lead to overlooking the trachea. Before the trachea, pre- viously exposed sufficiently, is opened, all bleeding vessels, are closed by ligature. A tenaculum is introduced into the trachea for the purpose of placing the organ at rest at the level of the Avound, as it would otherwise rise and fall with the respiratory movements, especially in the presence of dyspnea. The opening into the trachea should be made exactly in the middle line, care being taken that the incision enters the lumen of the tube and does not ]^ass beyond. If the opening is incomplete, it may happen that the tracheal cannula makes a false passage for itself beneath the mucous membrane. A careless incision may, further, injure the posterior wall of the trachea or even the esophagus. After the trachea has been opened the OPERATIONS ON THE AIR-PASSAGES. 283 incision is dilated hy means of tenacula, while at the same time as the cannula is introduced the trachea is held steadily. The latter precaution is important, as through its neglect the o{X'ning may be lost to view in consequence of the movements of the trachea. A])art from the fact that such an event may render impossible the proper in- troduction of the cannula, subcutaneous emphysema may result and extend from* the wound to the cellular tissue of the neck. The cannula (Fig. 178) in accordance with its curvature is introduced in an arched manner. The whistling sound Fig. 178. — Tracheal cannula. Fig. 179. — Trendelenburg's tampon- cannula. with which the air, after a short period of apnea, escapes from the tube is the indication that the cannula is properly placed. In tixing the cannula by means of the tapes the tube must be held firmly in the wound. Tracheotomy for the puqx)se of tamponade of the trachea, with simultaneous insurance of access of air, is sometimes ])ractised as a preliminary procedure in opera- tions upon the mouth, the larynx, and the pharynx. The tampon-cannula is intended to prevent the entrance of blood in the course of operations and the aspiration of 284 OPERATIVE SURGERY. secretion from wounds in the further progress of the case. The so-called tampon-cannula employed for this purpose is surrounded with compressed sponge (Hahn), which swells in the trachea and completely occupies its lumen ; or, the tube is surrounded l^y a small rubber bag (Tren- delenburg) which can be filled with air by means of bellows (Fig. 179). The l)ag is distended with air after the cannula has l^een introduced, and adapts itself accu- rately to the interior of the trachea, occluding its lumen as a stopper does the neck of a flask. Intubation. — Intubation is a bloodless procedure in- tended to render the larynx patulous in the presence of respiratory obstruction by the introduction of a rigid tube. The operation was recommended a number of years ago as a substitute for tracheotomy in cases of laryngeal stenosis from croup, and it has in the course of time secured more and more supporters. The most important indication for intubation consists in laryngeal stenosis such as is observed in conjunction with laryngeal croup. Further indications are afforded by the various forms of chronic stenosis of the larynx observed in adults. Under these conditions intubation is a substi- tute for tubage. Intubation has been recommended also as a palliative measure in cases of whooping-cough and of laryngeal spasm. The procedure is contraindicated : (a) In the presence of complete occlusion of the naso- pharyngeal space ; (6) In the presence of intense edema of the glottis ; (c) In cases of diphtheria complicated by retrophar^m- geal abscess. The original outfit of O'Dwyer is still the best, in spite of numerous modifications. This consists of: (1) A mouth-gag (Fig. 180). (2) A series of metallic tubes of varying size (Figs. 181 and 182). Each tube presents at its upper extremity a shoulder resembling the rim of a hat, by means of which it rests upon the vocal bands. Upon the left side of this shoulder is a small opening for the attachment of a thread.

By means of a lever the tube can be detached from the conductor at the proper moment. (4) An extubator (Fig. 184). The extremity of this instrument, which is constructed similarly to the intuba- tor, can be introduced into the lumen of the tube, and be impacted there, and thus serve for the removal of the tube.

An assistant holds the mouth oj)en by means of the gag, while the operator grasps the epiglottis with the index- linger of his left hand and draws it forward so that the entrance to the larynx is clear.

The first row of sutures approxi- mates the mucous membrane and the second the muscular layer. If the operation has been performed for the pur- pose of establishing an esophageal fistula — for instance, for dilatation of a stricture of the esophagus — the margins of the mucous membrane are united to the skin by means of knotted sutures. lyigation of Vessels in the Cervical Region. — Innominate Artery. — The innominate artery, the common trunk of the carotid and the right subclavian artery, arises from the arch of the aorta. Lying against the trachea, the large vessel passes to the right and upward, dividing into the two vessels named at the level of the sterno- clavicular articulation. Covered bv the manubrium of the sternum, the innominate artery is accessible from the suprasternal fossa behind the free border of the sterno- hyoid or of the sternothyroid muscle. The trunk of the vessel is crossed by the left innominate vein as it passes transversely. The recurrent laryngeal nerve winds around the innominate artery. In ligating the vessel the patient occupies the dorsal decubitus, with the neck extended. According to Graefe, the cutaneous incision is made along the anterior border of the sternomastoid muscle in such a way that its lower extremity extends beyond the sternal 292 OPERATIVE SURGERY. attachment of the muscle. The sheath of the muscle is opened and the median fascia of the neck divided, when the inner border of the sternohyoid becomes visible and below tliis that of the sternothyroid. These muscles are retracted witli blunt hooks. Along the right side of the trachea progress is made downward, the common carotid artery being first reached and further on the innominate, lying by the side of the trachea. The artery can be iso- latecl from the surrounding loose cellular tissues by blunt dissection and it is then ligated. The same plan of procedure is followed in looking for the vessel through an incision made vertically in the mid- dle line of the neck over the suprasternal notch^ instead of the incision of Graefe. Carotid Artery. — The carotid artery on the right is a branch of the innominate, while upon the left it arises directly from the arch of the aorta. The common carotid artery on either side passes along the side of the trachea and the larynx almost vertically upward upon the neck to the level of the thyroid cartilage, where it divides into its primary branches, the internal and the external carotid. In its course the carotid artery holds such relations with the jugular vein, the vagus nerve, and the descending branch of the hypoglossal nerve in the loose cellular tissue that the vein lies to the outer side of the artery. The vessels are covered by fibrous fascia that also constitutes the poste- rior w^all of the sheath of the sternomastoid muscle. To render the artery accessible it will thus be necessary to expose and retract the fibers of the sternomastoid muscle and to divide carefully the posterior wall of its sheath. Ligation of the Common Carotid Artery. — The patient occupies the dorsal decubitus, Avith the neck stretched and the head rotated toward the healthy side. By palpation the situation of the larynx and the course of the sterno- mastoid muscle are determined. The artery is best ex- posed at the level of the cricoid cartilage just above the point where it is crossed by the omohyoid muscle. The cutaneous incision is made along the anterior border of the LIGATION OF VESSELS IN CERVICAL REGION. 293 sternoinastcud from the thyroid ciirtihige for a distance downward of 8 or 10 cm. (Fig. 186, />;). After the skin and the platysma muscle are divided the sternomastoid muscle, covered hy the fascia, comes into view. The fascia is divided in the direction of the cutaneous incision and the inner border of the exposed muscle is carefully retracted outward, when the so-called middle fascia of the Fig. 186. — Ligation of the vessel- tIiun ot the glossal nerve, accom- panied by a vein, passes horizontally. The free border of the mylohyoid muscle forms with the tendon of the digas- tric muscle and the hypoglossal nerve a triangle whose floor is constituted bv the fibers of the hvocflossus muscle.

Plate 17.— Exposure of the Lingual Artery. The submaxillary gland (.S'm) is raised from its bed after division of the skin and the fascia ; the lingual trigone is thus rendered visible.

LIGATION OF VESSELS IN CERVICAL REGION. 297 tiihcrclc ot" JiislVaiu; or the scalene liil)erele. The cords of the brachial ])lexus also reach the arm through the in- ters al between the two scalene muscles. The nerves lie al)ove and to i\\v outer side of the artery (IMate 18). The subclavian vein passes in the interval between the sternomastoid and the scalenus anticus (anterior scalene interval), to unite ^vith the internal jugular vein. The subclavian vein is thus separated from the subclavian ar- tery by the scalenus anticus muscle. The subclavian artery is exposed for ligation above and l)elow the clavicle ; in the supraclavicular fossa just at the point where it lies upon the iirst rib after emerging from the scalene interval ; below^ the clavicle at a point corresponding Avith the lower margin of the first rib. Liyutlon of the Subclavian Avtcry Above the Clavicle. — The patient lies with the upper portion of the trunk ele- vated and the head rotated toward the opposite side. The arm lies against the trunk. Gentle traction on the arm brings into view the boundaries of the supraclavicular fossa. By this means the clavicle can be seen, forming the base of the triangular space, whose anterior boundary is formed by the outer border of the sternomastoid mus- cle and the posterior boundary by the anterior border of the trapezius. The plane of the supraclavicular fossa is more or less depressed. A transverse cutaneous incision is made parallel with and a finger's breadth above the clavicle, from the outer border of the sternomastoid muscle to the anterior border of the trapezius (Fig. 186), dividing the skin, the pla- tysma muscle, and the supraclavicular nerves. By blunt dissection a passage is made through the loose connective tissue of the supraclavicular fossa to the deep layer of fascia that covers the scalenus muscles, the brachial plexus, and the subclavian artery. After the fascia has been divided, the position of the posterior scalene interval is made out, and the situation of the artery is determined by palpation with the finger just behind the attachment of the scalenus anticus to the first rib, to the outer side 298 OPERATIVE SURGERY. Plate 1 8. — Situation of the Subclavian Artery in the Supraclavicular Fossa. The anterior scalene interval is visible between the sternomastoid {K ) and the scalenus anticus (Sa) ; also the posterior scalene interval between the scalenus anticus and the scalenus medius {Sin). Through the latter space pass the nerves of the brachial plexus (N), and to the inner side of the nerves, lying upon the first rib, the artery. of the scalene tubercle. The artery lies upon the first rib at the deepest point of the interval, to the inner side of the nerves of the brachial plexus, and can be isolated for ligation between two pairs of anatomic forceps. Ligation of the Subclavian Artery Below the Clavicle. — The patient occupies the same position as in the operation just described. The line of separation of the clavicular portions of the deltoid and pectoralis major muscles is in- dicated below^ the clavicle by a triangular depression (Moh- renheim's triangle). By palpation ^vith the finger the situation of the coracoid process of the scapula is care- fully determined, and a cutaneous incision is made from a finger's breadth belo^y the clavicle to above the apex of the coracoid process. The clavicular portion of the pec- toralis major muscle is divided in the line of the cuta- neous incision and after division of the loose coracoclavic- ular fascia the upper border of the pectoralis minor is exposed and is retracted downward with blunt hooks. In the loose connective tissue below the clavicle there appear in the direction toward the anterior scalene interval above, the readily accessible subclavian vein, and to its outer side the great mass constituted by the brachial plexus. The artery lies betw^een the vein and tlie nerves, closer to the wall of the thorax, and can be separated from the loose cellular tissue by blunt dissection (Plate 16). Following another method, entrance is gained to Mohrenheim's tri- angle, after making the same cutaneous incision, and the artery is exposed without division of the pectoralis major. The superficial fascia is divided and after separation of the margins of the pectoralis major and deltoid muscles the 'WAk 1^ Sm.

III. OPERATIONS ON THE TRUNK AND THE PELVIS. Paracentesis Thoracis, Thoracotomy. — The thorax is opened by puncture or by incision wlien the presence of accumulations of fluid in the pleural cavity gives rise to threatening symptoms by reason of either their quantity or their character. In general the statement may be ac- cepted that serous and hemorrhagic elFusions are to be treated by puncture, and purulent exudates on the other hand by incision.^ Either operation is therefore always preceded by exploratory a.spiration of the pleural contents by means of a hypodermic or similar syringe. The ope- ration of thoracocentesis is performed by the introduction of 8 trocar and cannula between two ribs into the pleural space, either permitting the fluid simply to escape, or aiding its removal by means of aspiration. If the cannula is so constructed that the aspiration of air can be avoided during the removal of the trocar, the first method of pro- cedure meets all requirements. Billroth's cannula is provided with a lateral branch for the escape of the fluid, whicli can be controlled by a cock. To this branch a rub- ber tube of suitable length is attached. The branch of the cannula in which the stilet is introduced is also pro- vided with a cock, which is closed after the stilet has been removed. The patient is placed in the sitting posture with the trunk bent somewhat forward. The trocar is introduced, except in the presence of a sacculated efPusion, at the most marked convexity of the ribs in the fourth, fifth, or sixth intercostal space, and close to the upper border of the lower rib. The operator marks accurately the point of introduction with the index-finger of his left 1 If a hemorrhagic collection is very extensive and the life of the patient is seriously threatened, it is proper to open the thorax after rib-re- section and endeavor to arrest the hemorrhage by ligatures, by suture- ligatures, by packing a small pulmonary wound, or by filling the pleura with sterile gauze, to secure a point of counter-pressure, and packing iodoform-gauze directly against the bleeding lung. — Ed.

Troear and caniiida are introdnced verti- cally nntil disappearance of the resistance of the thoracic wall indicates that the point of the instrnment has entered the })lcnral ca\ity. The o]>erator now irras})s the instru- ment with his left hand, removes the trocar, and permits the fluid to escape through the lateral branch of the can- nula. The extremity of* the rubber tube dips into a ves- sel containing: aseptic fluid. The flow should take place steadily antl shjwly. By this mode of procedure the entrance of air is avoided with certainty. If the discharge of fluid ceases suddenly, the flow can be facilitated by changing the position of the cannula, if the obstruction be due to ap- proximation of the lung. Occlusion of the tube by coagula may be overcome by the introduction of a blunt probe. The evacuation of the fluid can be better controlled when with puncture is conjoined aspiration of the pleural exudate. In place of the trocar and cannula a sharp hol- low needle is employed, which is connected by means of a tube with the neck of an airtight bottle from whose in- terior the air is exhausted with the aid of a suitable pump (Dieulafoy's aspirator). Fluid can thus be evacuated by negative pressure when it would fail to flow spontaneously from the pressure withiu the pleural cavity. Thoracotomi/, opening of the pleural cavity by incision, is indicated when the pleural exudate is purulent in char- acter. Unless the exudate be sacculated or circumscribed, the incision is made in the fifth or sixth intercostal space over the greatest convexity of the ribs. To avoid injury of the intercostal vessels the knife is introduced close to the upper border of the rib, dividing the two layers of intercostal muscles, the endothoracic fiiscia, and the pleura throughout the entire extent of the incision. By the in- troduction of a rubber tube into the wound drainage of the pleural cavity will be established. To permit of more convenient access and to render possible adequate drainage resection of from 3 to 4 cm. of a rib in its contin\iity is recommended. Under these circumstances the incision 304 OPERATIVE SURGERY. is made directly over the rib, dividing its periosteum throughout a distauce of 5 or 6 cm. The periosteum is reflected upward aud downward by means of a raspatory from the anterior surface of the rib, and then with espe- cial care from its posterior surface. The portion of the rib thus exposed is resected throughout the given extent by means of bone-shears. The uninjured pleura is incised, the purulent contents permitted to escape, and drainage established. If in the presence of a pleural fistula the empyema cannot be made to close on account of the rigid- ity of the thoracic wall, resection of a series of ribs is a suitable procedure in order to render the wall of the chest more yielding. The possibility thus established of ap- proximating the parietal and visceral layers of the pleura renders the conditions favorable for cessation of the long- continued aud tedious suppui'ative process. A long, verti- cal incision exposes the series of ribs, which are to be subjected individually to subperiosteal resection through- out an extent of from 3 to 10 cm. Ligation of the Internal Mammary Artery. — The cuta- neous incision is made in the third or fourth intercostal space from the border of the sternum outward for a dis- tance of 4 or 5 cm. The skin, the subcutaneous connec- tive tissue, the pectoralis major, and the internal inter- costal muscle are divided throughout the extent of the incision. Lying in front of the pleura, in the angle between the rib and the sternum, is the internal mammary artery, which follows the axis of the body and is accom- panied by two veins. The vessel can readily be isolated from the loose connective tissue. Esmarch makes a longi- tudinal incision alongside the sternum and enlarges the field of operation by resection of a costal cartilage. Removal of the Mammary Gland. — The mammary gland is removed completely Avhen the seat of a malig- nant neoplasm. AYith the gland are also removed en masse the chain of lymph-glands extending from it to the axillary cavity and the mass of axillary lymphatic glands in conjunction Avith the fat by which they are OPKIiATloys OX THE TJiUyK ASD Till-: PELVIS. 305 surroiiiKU'd.

The healthy skin is disseeted free from the subjaeent structures and when the margin Fig. 188. — Amputation of the breast : cutaneous incision. of the gland has been reached this is removed from the thoracic wall Avith the upper layers of the peetoralis major, or in conjunctir>n with the whole muscle. The separation is effected throughout the entire extent of the mammary irland with the exception of the pole directed toward the axilla. Then the axillary fat and the con- tained lymphatic glands are removed en masse. The group of glands remains in connection with the breast. From the upper pole of the oval, which is directed toward the axillarv cavitv, an incision is made alonj; the free 20 306 OPERATIVE SURGERY. border of and down to the pectoralis major muscle. The lower margin of the wound is retracted downward, and the pectoralis major upward. Beginning at the pectoralis major, the mass of fat is detached by means of anatomic forceps from the group of large vessels and nerves. Of especial importance in this connection is the large axillary vein, which lies uppermost and whose separation is to be effected with especial care. As the dissection progresses it will become necessary to divide between t^^o ligatures the trunks of arteries and veins passing between the groups of glands drawn downward and the large vessels. After the glands have thus been separated from the large vessels, the subscapularis and latissimus dorsi muscles are yet to be dissected. The connections between the group of glands and these muscles are quickly divided with the knife, when the entire mass of axillary fat may be removed en masse in conjunction with the breast. Under some cir- cumstances the subscapular artery and vein, the posterior circumflex artery and vein, or the long thoracic artery and vein may require ligation. Klister has called attention to the importance of protecting the long thoracic nerve from injury. If it prove impossible to free the axillary vein, it often becomes necessary to sacrifice a portion of this vessel. After the application of ligatures the vein is resected throughout the necessary extent and removed together witli the glands. For the removal of infiltrated glands from the infraclavicular and supraclavicular fossae accessory operations are necessary. Transverse division of the pectoralis major and minor muscles will render the infraclavicular fossa conveniently accessible. For the re- moval of supraclavicular glands either an incision is made as in ligation of the subclavian artery above the clavicle, or the clavicle is divided temporarily at the junction of its middle and outer thirds.^ ^ The operation of Halsted is extensively employed in the United States. In this operation the surgeon removes the entire breast and the skin over it, the axillary glands and fat, and the pectoral muscles. The mass is removed in one piece. In many cases the subclavicular glands and fat are also removed. — Ed. OPERATIONS ON THE TRUNK AND THE PELVIS. '607 Abdominal Puncture, Paracentesis Abdominalis. — The aUlomiiKil cavity may he opciu'd by puiK'tiire to eticct cvaouatioii ot Hiiid accuinulations, either free within the peritoneal cavity, or saeenlated, or contained within cysts. [f the Huid be free, the ]i()int of ^lonro, that is, a ])oint midway between the uml)ilicii> and the left anterior iliac spine, is as a rule seleeted as the situation for puncture. Trzebizky has demonstrated tliat in a small })roporti()n of eases the epigastric artery or one of its branches may be injured in performino puncture by this method. If, liow- ever, the troear is introduced into the outer half of the line between the umbilicus and the superior iliac spine, the possibility of this unpleasant occurrenee is safely avoided. The reeommendation to make the puneture upon the left side of the abdomen is not of primary ira- portanee. If the liver be enlarged, the puncture will be preferably made upon the left side. Enlargement of the spleen of an}' considerable degree will justify making the puncture upon the right side. The puncture may further be made in the linea alba, midway between the umbilicus and the symphysis pubis. The selection of the point of puncture in the presence of cysts and of sacculated exu- dates will be o'overned bv the situation of the accumula- tion of fluid. In performing puncture of the abdomen a straight trocar and cannula with a lateral branch are employed. The patient occupies a partial lateral position or the upper portion of the body is elevated. Before the trocar is in- troduced it should be determined by careful percussion that the mtestine is not adherent to the abdominal wall at the |X)int where the puncture is to be made. The index- linger of the left hand is placed at the point of puncture, and the trocar is introduced vertically through the ab- dominal walls, then grasped Avith the left hand, while the right removes the troear. By means of a tube attached to tiie lateral branch of the cannula the fluid is permitted to esca[)e slowly into a suitable receptacle. If the intra- abdominal pressure falls, the escape of the fluid is favored 308 OPERATIVE SURGERY. by compression of the abdomen with the hand or by tightening a many-tailed bandage around the abdomen. It is an old rule never to permit the escape of all of the fluid contained within the abdominal cavity. The trocar is therefore removed at a time when a certain amount of fluid is yet present, and the wound is closed with a suit- able dressing. Celiotomy. — Opening of the abdominal cavity through incision of the abdominal walls is designated celiotomy. This procedure is a preliminary one in the performance of intraperitoneal operations of all kinds. The abdominal incisions are sometimes made longitudinally, sometimes more or less obliquely, and sometimes even transversely. Longitudinal incisions are made either in the linea alba, or along the outer border of the rectus abdominis muscle. In the epigastrium and the hypogastrium, both oblique incisions parallel with the costal margin, or with Poupart's ligament, and longitudinal and transverse incisions are employed. The incision into the linea alba is indicated in the presence of large formations occupying the abdomi- nal cavity. The incision is made below the umbilicus when the pelvic organs are the object of attack. Through the epigastrium access is gained to the stomach, or upon the right side to the liver and the gall-bladder. An incision is made into the hypogastrium when it is intended to reach upon the right the cecum or the vermiform appen- dix, and upon the left the descending colon or the sigmoid flexure (Fig. 190). In the performance of intraperitoneal operations the patient is either placed horizontally or the body is placed upon an inclined plane with the head at the lowest and the pelvis at the highest level (Trendelen- burg's position, Fig. 189). This position affords a clear view of the arrangement of the pelvic organs after the abdominal cavity has been opened, the intestmes sinking down toward the epigastrium in the concavity of the diaphragm. The position therefore permits careful in- spection of the abdominal viscera and protects the intes- tines from extrusion during the course of the operation.

As a rule, the median borders of the recti muscles are exposed witliin the wound. After division of the posterior layer of the sheath of the rectus a layer of loose connective tissue comes into view, and in obese persons a layer of fat often of considerable Fig. 189.— Trendelenburg's position. extent lying directly upon the peritoneum. All of the tissues are carefully divided by blunt dissection with two pairs of forceps.

Longitudinal, oblirjue, or transverse incisions in the epi- gastrium extend also, like those in the hy})ogastrium, successively through the layers of the abdominal muscles to the subserous fiit and the peritoneum. A fold of the parietal peritoneum is picked up with two pairs of forceps 310 OPERATIVE SURGERY. and snipped with scissors, and the incision is enlarged in the manner already described. The closure of the ab- dominal wall should be firm and resistant ; the resulting cicatrix should display no tendency to ectasis and the Fig. 190. — Ahdoniinal incisions: «, lonijitudiniil incision for opera- tions on tliestoniacli ; h, incision for ujastrostoiny ; c, incision for oi)erat.ions on the gall bladder; (L incision for epicystotoniy ; c, incision for ligation of the external iliac artery; /, incision for colotomy ; g, incisions for ex- posure of the cecum and the vermiform appendix. formation of ventral hernia.

The most superiicial layer of sutures unites the skin in the customary manner. In the same way abdominal wounds* in other situations are closed by three tiers of sutures. The deepest row unites the peri- toneum, the middle the muscle and the aponeurosis, and the upper the skin. Operations on the Stomach and the Intestines. — The Establishment of Gastric and Intestinal Fistulse. — In general the operation consists in bringing the selected portion of stomach or bowel out of the wound after celi- otomy and uniting the parietal peritoneum at the margins of the abdominal wound throughout a sufficient extent with the visceral peritoneum of the stomach or intestine by means of interrupted or continuous sutures. The stom- ach or bowel is opened either at once, the gastric or intestinal mucous nieml)rane being united to the skin, or in the course of several days, after the abdominal cavity has been closed through the formation of adhesions throughout the extent of the wound. The method of operation is subject to various modifications at different portions of the gastro-intestinal tract. The Formation of a Gastric Fistula ; Gastrostomy. — The formation of a gastric fistula is indicated in the presence of imj)ermeable constriction of the esophagus : (a) In consequence of the presence of neoplasms ; (h) In consecjuence of cicatricial stricture; as well as for the introduction of nourishment into the stomach and for purposes of dilating deep-seated strictures through the wound. The stomach is reached by division of the abdominal \vall in the left epigastric region. The cutaneous incision is made either parallel with the left costal margin or vertically through the rectus abdominis muscle close to 312 OPERATIVE SURGERY. Plate 19. Gastrostomy.— Suturing one portion of the anterior wall of the stom- ach into the wound in the abdominal wall. The serous margin of the wound is united with the serous layer of the stomach by means of a continued suture. Colostomy.— A loop of the sigmoid flexure has been drawn forward and fixed in the wound. its outer border. In the first instance the incision begins a thum])'s breadth to the left of the apex of the ensiform cartilage and passes ont^vard and downward for a distance of 6 or 8 cm. some 2 cm. from the costal margin. The peritoneal cavity is opened throughout the extent and in the line of the cutaneous incision, and a small portion of the stomach is brought into the wound. The stomach may be recognized by the characteristic radiation of the vessels from the greater and lesser curvatures. The walls of the stom- ach are thicker than those of the small intestine: and the organ is to be distinguished from the large intestine by the absence of sacculation. The stomach is most readily reached by grasping a portion of the great omentum and following it from the periphery toward the greater curva- ture. The portir)n of strmiach brought into the wound is suspended in position by means of two fixation-sutures that do not penetrate its lumen. The parietal peritoneum is then closely united to this portion of the stomach with a continued suture, including not only the thin serous layer, but al.-r^o the sul>.mc impossihk'; for instance, after ero- sion or corrosion of the stomacli ; also when the stomach is the scat of a new-formation, whose extent forl)ids either its removal or gastro-enterostomy. The incision is made in the linea alba, between the umbilicns and the sym- physis pubis. After the' peritoneum has been divided the transverse colon is brouoht forward at the attachment of the greater omentum and reflected upward. The duodeno- jejunal flexure appears at the root of the mesentery. One of the up])ermost loops of jejunum that ean be readily drawn into the wound is brought forward and fixed in the wound by means of seroserous sutures. The intestinal loop is opened either after the lapse of several days, or, Ix'tter, at once, with the establishment of an oblique fistula by the method of AYitzel. The nourishment of the patient ean be effected without difficulty through the rub- ber tube. As the oblique fistula closes accurately bile and pancreatic secretion are not lost. Resection of the Bowel. — It has been established clinic- ally that considerable portions of the intestine (two meters and more, Kocher) can be removed by resection without detriment. After the resection has been effected the continuity of the bowel can be restored by means of cir- cular suture of the stunq^s, or these may be brought out of the abdominal wound and an intestinal fistula or pre- ternatural anus established. Resection of the bowel is undertaken : (1) In the presence of injuries of the intestine; (2) In the presence of gangrene of the bowel ; (3) In the presence of neoplasms ; (4) In the presence of stenosis of the bowel ; (5) For the cure of intestinal fistulfe. The portion of intestine intended for resection must be detached from its surroundings, so that it can be brought out of the abdominal w^ound. The intestine is closed by means of either clamps or pressure with the fingers or 316 OPERATIVE SURGERY. strips of sterilized gauze tightened and tied. The con-, tents of the bowel should have been furced backward and forward before the intestine is incised. The division of the bowel is effected with scissors. The plane of division should be so made, according to the suggestion of Kocher, that a greater portion of bowel is removed from the con- vexity than from the mesenteric attachment, as by this means the circular vessels of the bowel are less exposed to injury. The mesentery is ligated in successive portions and divided transversely at its attachment to the bowel, or excised in the form of a wedge whose base is formed by the resected bowel and imited in a linear direction. After the mucous meml^rane projecting from the divided surfaces has been dried with sterile gauze circular union of the lumen of the two portions of bowel may be pro- ceeded with. If the lumen of the two portions of bowel is unequal, the smaller is divided obliquely, so that the cut surface is elliptic in shape. For the union of transversely divided bowel after resec- tion, as well as in the formation of anastomoses, either the intestinal suture or Murphy's anastomotic button may be employed. The method of applying the intestinal su- ture has already been described at page 53. Murphy's button renders possible rapid effectuation of accurate union of divided intestinal lumen, as well as the estab- lishment of anastomoses between portions of the intestinal tract. This ingenious device consists of two capsules made of light sheet-iron and nickel-plated and provided Avith a hollow cylinder internally and a slight shoulder externally (Plate 20), which can be readily pushed the one into the other with the lingers, when by reason of a clamp-like arrangement they remain thus in secure appo- sition. The transversely divided portions of intestine, or the slits made in the establishment of anastomoses, are picked up by continued sutures passing through all of the layers of the intestinal wall, which are tied after the intes- tine has been brought over the respective half of the but- ton. After the second portion of the intestine has been OPERATIONS ON STOMACH AND INTESTINES. 317 similarly treated the two halves of the button are pushed one into the other and elanipcd Ix'tween the tinh)n, and nninn of the opixtsed paits is ettected either hy suture or with the aid of the Murphy button. The first row of sutures includes the entire thickness of the intestinal and gastric walls, at the margins of the resjx'ctive openings. A row of Lembert serous sutures is applied over the first row. Operations upon the Biliar>" Apparatus. — Beside abscesses and cvsts of the liver, tor who-*.- operative treat- ment no especial rules can be laid down, attacks u}xjn tlie biliary apparatus are directed especially toward the removal of calculi and their sequelae. The surgery of the biliary apparatus, the youngest department of ab- d«)minal surgery, has been systematically practised only since the besrinninor of the eighties. The cutaneous incisions throuofh which the transverse fissure of the liver is reached are varied. At times it is made in the linea alba between the umbilicus and the symphysis pubis. At other times it is made along the outer border of the rectus abdominis muscle. Czeruy makes an anirular incision, whose vertical arm passes along the linea alba, and is joined below the umbilicus by a horizontal incision pass- ing towai\l the right and outward. In all cases after opening the peritoneal cavity the right lobe of the liver is reflected upward sseladder will escajx? after slight withdrawal of the soft catheter.

In general the rule is to be ob.served that the beak of the instrument be made to pass along the upper wall of the urethra. If the urethra l)e normal, no difficulty is experienced in the operation until tlie meml)ranous portion is reached, but at the junction of the movable with the fixed membranous j)ortion a slight obstruction is encountered l)v the beak of the catheter (Fig. 198). Care must now be taken to pre- 328 OPERATIVE SURGERY. vent the tip of the instrument engaging in the mucou« meml)rane. The beak most therefore not deviate from the median line, and with cautious movements the instru- ment should be passed into the membranous portion, naturally without any violence. After the resistance has been overcome the instrument Avill be felt to enter the membranous portion and pass through the urogenital diaphragm. From this point the catheter in a normal urethra en- counters no further obstruction, and on dopressinuf the Fig. 199.^Introduction of a rigid instrument into the bladder: by depressing the shaft of the catheter its beak is forced iuto the bladder.' handle of the instrument the tip enters the bladder with- out further hindrance (Fig. 199).

With a slight jerk the tip of the instrument passes the bulbous portion and it yet remains to enter the membranous por- tion and pass the urogenital diaphragm (Fig. 201). In all cases a sense of obstruction is encountere<:l at this point which is readily overcome by gentle pressure, while 330 OPERATIVE SURGERY. the catheter is held accurately in the median line, and is gradually depressed from the vertical to the horizontal toward the lower extremities (Fig. 202). If the instrument is at the same time pushed forward slightly, its tip enters the bladder. At this moment urine will escape from the catheter. AVith the rigid instrument, as soon as the prostate has been passed and the bladder has been entered, free movements can be made with the tip of the instrument. The method of introducing the catheter described is attended with difficulty in obese individuals and in the presence of meteorism and ascites. Under such circum- stances it seems desiral)le to enter the catheter at ri^ht angles to the axis of the body, with the penis raised ver- tically. In this position the instrument is pushed forward and at the same time rotated in an arc to the median line and elevated to a position until the tip is grasped by the bulbous portion (Fig. 203). In another mode of pro- cedure the operator sits before the patient, who is placed in the position for the operation of cutting for stone. The catheter is introduced into the orifice of the urethra from between the extremities of the patient, with its convexity directed upward. The penis, raised vertically, is drawn over the curve of the catheter and the instrument is rotated through an arc of 180° t(^ward the right until it reaches the median line. During the progress of these manipulations the beak of tlie instrument enters the urethra to the bulbous portion. Now, the handle of the catheter is elevated and pushed forward in the median line until its beak has passed the posterior urethra and entered the bladder. Ill a normal urethra an instrument of considerable weight, as for instance a rigid sound of large caliber (lithotriptor), overcomes readily the obstruction encountered on the distal side of the bulbous urethra and glides easily, by reason of its own weight, into the bladder, without further guidance. The guiding hand need only prevent the departure of the instrument from the median line. In the presence of narrowing, however, a certain amount of pressure in the direction of the urethra is necessary, in order to urge the instrument ouAvard through the rigid cicatricial tissue. If the urethra is narrowed in its deeper portion, or, if OPERATIONS UPON GENITO-URINARY ORGANS. 331 .- i> ^ s i> 4^ -1-3 o U-, -t-- ^ ■*-> -u o !h O "tL p. ^ W — 3 ^— - -t-3 >^ 'tx ; :« ' r^ ^ Xi rS a i^ft/^ OPERATIONS UPON GENITO-URINARY ORGANS. 333 the prostate is enlar«;ed it will often be necessary to introduce the index- finger of the left hand into the rectum as a guide. In the presence of hypertrophy of the prostate, on account of elongation of the prostatic portion of the urethra, and on account of elevation of the orifice of the bladder, the catheter or the sound must be introduced for a greater dis- tance and be more greatly depressed, iu order that the beak may reach into the bladder. Catheters for introduction into the female urethra cor- respond with the shortness of this canal, and are either Fig. 202. — Catheterization : the catheter has entered the mem- branous portion and has passed the urogenital diaphragm; by pressing the handle the tip enters the bladder. straight, or slightly curved at their extremity. In intro- ducing the instrument the labia are separated and the handle is depressed while the catheter is ])ushed forward. Only in the presence of pregnancy or of tumors of the genital oro^ans may the female urethra be elongated or dis- torted. The resulting difficulty in the introduction of a catheter is to be overcome by the employment of par- tially rigid instruments, as in males. 334 OPERATIVE SUBGEBY. Retenilon-catheter. — A catheter may be permitted to remain Avithin the urethra for days or even weeks. In order to serve its purpose permanently it must be suitably fixed in position. The introduction of a retention-catheter into the urethra permits constant escape of urine, Avhich, beside, does not come in contact with the wall of the urethra. Such a form of catheter is therefore employed when it is desired to place the bladder at rest, to secure a Fig. 203. — Mode of introducing the catheter from the side. permanent channel of escape for the urine and finally when the urethra is to be spared irritation. The moderate but constant pressure of the retention-catheter softens cica- trices of the urethra and exerts a dilating influejice upon circular strictures, and for this reason is a])plicable with advantage in the presence of callous and cicatricial strict- ures of the urethra. Finally, the retention-catheter is to be recommended when catheterization that must be fre- OPERATIONS UPON GENITO-URINARY ORGANS. 335 qucntly repeated is attended either with difficulty or with iinpk'asant results, sueh as hemorrhage and urinary fever. The soft catheter of vulcanized rubber is, as a rule, em- ployed as a retention-catheter. The instrument is intro- duced to a sufficient depth for the urine; to escape without interruption. A suitable pin is introduced transversely C I B R I I Fig. 204. — Fixation of the retention -catheter by the method of Dit- tel : A, B, C, forms of the strips of adhesive plaster ; I, II, III, modes of applying the plaster to the penis. through the catheter just in advance of the orifice of the urethra and its point broken off. Strips of adhesive plaster are prepared in the manner indicated in Fig. 204. The square incised strip with an opening at its center is applied upon the glans in such a way that it supj^orts the pin passing through the catheter (Fig. 204, /). The 336 OPERATIVE SURGERY. longer strip slit in the middle is drawn over the catheter, and comes to rest upon the needle, being made to adhere to the sides of the penis (Fig. 204, //). The entire ar- rangement is made secure by circular turns of strips of plaster passing around the oro^an from the glans to the root (Fig. 204, ///). Puncture of the Bladder. — Evacuation of the bladder througli suprapul^ic puncture is undertaken as a pallia- tive measure, and also for the puqiose of forming a vesical fistula through the abdominal wall. Palliative puncture is practised in the presence of complete retention of urine in consequence of impermealjle stricture of the urethra when it is desired to await a more favorable time for the introduction of a sound or for the performance of a radical operation for the relief of the obstruction. For the pur- pose of establishing a vesical fistula the operation is undertaken (1) in the presence of prostatic enlargement, with complete or incomplete retention of urine, when catheterization is attended with difficulty or is followed by hemorrhage ; (2) when the mouth of the bladder is obstructed by a tumor that cannot be removed by opera- tive measures; (3i to effect drainage of the bladder in cases of severe purulent cystitis. If the object of the procedure is only evacuation of the bladder, the pimcture is made with a thin, so-called exploratory trocar. The operation is in itself of little significance and, if necessary, can be frequently repeated. The patient lies upon his back, with the pelvis somewhat elevated. As the punc- ture is always undertaken by reason of retention of urine, the bladder is distended to the maxinunn. and is readily palpable as a tumor above the symphysis pubis. The operator stands to the right of the patient, and marks with the tip of his left index-finger a point in the middle line just above the symphysis where the puncture is to be made. The trocar is pushed vertically through the ab- dominal wall, disappearance of the sense of resistance indicating that the point of the instrument has entered the bladder. The cannula is grasped with the thumb and OPERATIONS UPON GENITO-VRINARY ORGANS. 337 the indox-tinger of tlie let't luiiul and the stilet iri removed with the right. After the urine has eseaped, the eannula is removed, its extremity being closed with the tip of the thumb in order that the wound be not eontaminated. Tlie wound of puncture invariably heals without compli- cation. If in conjunction with jnmcture a vesical fistula is to be established in the abdominal wall the operation is to be performed with the aid of the semicircularly curved trocar of Fleurant (Fig. 205). The position of the patient and of the operator is the same as that just de- scribed. The index-finger of the left hand marks the point accurately in the middle line just above the symphy- sis, where the puncture is to be made. The instrument Fig. 205. — Trocar for puncture of the bladder, after Fleurant. is applied vertically and pushed forcibly through the ab- dominal wall. When the disappearance of resistance indicates that the abdominal wall has been passed the instrument is pushed onward and its handle is raised so that its extremity is directed toward the fundus of the bladder. The stilet is now removed (Fig. 207) and a suitable tube passed through the cannula. The cannula remains in place for about a week, after which a Nelaton catheter is introduced into the fistula and fixed in the wound. External Urethrotomy. — External urethrotomy consists in entering the urethra through an incision in the abdomi- nal wall. The operation is undertaken (1) in the presence of calculi and foreign bodies in the urethra, whose removal 22 338 OPERATIVE SURGERY. cannot be effected through the natuml passages ; (2) in the presence of injuries of the urethra ; (3j in the presence of strictures of the urethra which are either impermeable or not accessible to treatment by dilatation for various rea- sons ; (4) for the establishment of a urethral fistula ; (5) as a preliminary operation to median section for stone. Fig. 206.— Puncture of the bladder: position for making the puncture. The mucous membrane of the urethra is readily reached with the knife in its pendulous portion after division of the skin, the dense fascia, and the corpus spongiosum. The bulb of the urethra is accessil)le in the middle line through an incision in the perineal raphe, after division of the skin, the tunica dartos, the superficial perineal fascia, and the bulbocavernosus muscle. The corpus OPERA TIOXS UFOX GEyiTO-URINARY ORGAXS. 339 spongiosoum is thicker in this situation than elsewhere, so that the urethra lies at greater depth than common.

If it i.s desired to reach the membranous or the prostatic portion, the muscular and fibrous connections between the anus and the prostate gland must be divided transversely, when after blunt dissection of the rectum, 340 OPERATIVE SURGERY. which is reflected toward the sacrum, the proximal por- tions of the urethra, the membranous portion and the prostate are rendered visible and accessible to surgical intervention. The performance of urethrotomy is subject to'various modifications in accordance with the indications for the operation. The patient lies upon his back with the lower extremities flexed at the knee and the hip (position for cutting for stone). The operator is seated in front of the patient. The urethra is invariably opened in the median line through the raphe of the perineum. Urethrotomy icith a Guide. — A metallic sound grooved upon its convexity is introduced into the urethra to a point beyond the constriction that is to be divided. The guide is held by an assistant accurately in the middle line. If the incision is to be made into the perineum, the scrotum is lifted up. The operator determines by touch with the finger the position of the resistant portion of the urethra, which is perhaps a stricture surrounded by callus, and makes an incision over it in the middle line. If the nar- rowing be at the junction between the bulbous and mem- branous portions, the incision passes from the root of the scrotum almost to the anus. By dissecting layer by layer in the median line the callous and narrowed portion of the urethra is reached and an incision is made in the line of the cutaneous wound until the groove in the guide is ex- posed. The callus is divided up to a point where the urethra is of normal caliber. The introduction of a re- tention-catheter concludes the operation. Urethrotomy icithout a guide is an incomparably more difficult operation than that just described. The operator occupies the same position as in cutting for stone. The sound can be introduced only to the anterior portion of the stricture if this be impermeable. The cutaneous incision is made as in the operation just described, in the median line through the perineal raphe. The portion of the urethra lying to the distal side of the constriction is incised and the margins of the wound are separated by OPERATIONS UPON GENITO-URINARY ORGANS. 341 means of small tonaciila. An effort is made to find tiie lumen of the constriction and to gain entrance by means of a thin bulbous instrument. If this can be done, the cicatricial tissue is dividcjd in the middle line on its under surface to the sound, and the incision is continued beyond the narrowing of the urethra. As a rule, the detectipn of the canal of the urethra at the distal extremity of the stricture is attended with diffi- culty. The tissues are changed from the presence of cicatrices, and the hemorrhage from the cavernous bodies and from the bulb is often considerable, so that it can be readily understood that the small lumen of the urethra may escape detection in the limited field of operation. Indiscriminate incision into the callus is not to be com- mended. By means of manual expression of the bladder it may be possible under circumstances to cause the escape of a few drops of urine into the wound and in this way to gain an idea as to the situation of the orifice of the strict- ure. If it has been possible by this means, under guid- ance of the eye, to introduce a bulbous bougie into the orifice of the stricture, the division of the narrowed por- tion of the urethra will be unattended with any further difficulty. After division of the stricture a catheter of consider- able caliber can always be introduced with aid from the Avound through the entire urethra into the bladder. In the event of failure to divide the stricture through the wound there remains yet the resource of retrograde sound- ing of the stricture, j^ostenor catheterization. This may be undertaken : (1) Through the urethra, after exposure and incision of the urethm to the proximal side of the stricture ; (2) Through the bladder, after this has been opened by means of a suprapubic incision. In performing retrograde catheterization through the urethra the deeper portions of this canal (the membranous portion) are exposed by detaching the lowermost ex- tremity of the rectum. To this end the perineal longi- 342 OPERATIVE SURGERY. tudinal incision is either prolonged to the anus or the detachment of the rectum is undertaken through a pre- rectal curved incision. After division of the skin the connections between the sphincter ani and the bulbocaver- nosus muscles are divided transversely and then the anterior wall of the rectum is freed by blunt dissection from the cutaneous covering. If the bulb of the urethra is retracted upward and the rectum downward, the mem- branous portion can be dissected in the upper angle of the wound. The meml^ranous portion, which is readily palpable as a rounded prominence, is incised longitudi- nally for a distance of about 1 cm., and retrograde sound- ing can be practised through the narrovred portion, which is then divided. Retrograde sounding of the stricture can be practised also from the bladder, after this has been opened through a suprapubic incision. The patient lies upon his back, with the pelvis elevated, and the bladder is opened in the usual manner above the symphysis pubis. The incision in the bladder is held open by tenacula and an English catheter of small caliber is pushed forward under the guidance of a finger through the neck of the bladder into the urethra to the point of obstruction. The patient may be placed in the position as for the operation for stone, the wound in the perineum held open by tenacula and the stricture is passed or merely entered by pushing the catheter forward from the bladder. In the first event the stricture is divided down to the catheter; in the second, the portion of the urethra lying to the proximal side of the stricture is opened and the stricture itself is successively divided with scissors from behind forward. The last step is, as a rule, effected without difficulty. Urethrotomy is indicated after traumatic rupture of the urethra, complete or incomplete, when catheterization is attended with difficulty, or urinary infiltration is threat- ened. The incision is made through the perineum in the raphe, over the greatest prominence of the perineal bulg- ing that is always present.

The stone is now removed in the typical manner. The lateral and median incisions for stone, which in the past were the customary operations, possess to-day but a limited field of application, having been almost completely displaced by the suprapubic incision. [Dis- placed particularly by litholapaxy. — Ed.] The median incision, the more recent of the two, was chosen in order to avoid the division of the ejacu- latory ducts that has heen observed repeatedly as a result of the lateral incision. Both methods are attended with the disadvantage that the removal of large stones through the narrow wound-canal can be effected only with difficulty, so that the wound itself is distorted and lacerated in the efforts at extraction and dilatation and the conditions for recovery are rendered less favorable than otherwise they would be. Finally, a typical form of true incontinence, permanent dribbling of urine, is not rarely observed after the median or the lateral incision, even when union has proceeded smoothly. Urethrostomy. — In cases of incurable stricture Poncet excludes entirely the narrowed portion of the urethra by means of perineal urethrostomy, dividing the urethra on the proximal side of the stricture and permitting it to open upon the perineum. The stricture is exposed by means of the usual incision through the perineal raphe, when the urethra is divided transversely on the proximal side of the stricture, and is sutured in the lower angle of the cutaneous wound. Poncet divides the central stump throughout a slight extent on its under side before suturing it in the wound. The peripheral stump of the urethra is sutured and dropped into the wound, when the cutaneous wound is closed by suture up to the opening of the fistula. Litholapaxy. — Instrumental endovesical crushing of stone in the bladder, followed immediately by evacua- tion of the fragments, is designated litholapaxy. The instrument for destroying the stone is made of steel, 346 OPERATIVE SURGERT. shaped like a catheter, and consists of two blades fitting one into the other and the tip of one of which is serrated. The instrument grasps the stone between its two blades, which can be secured firmly and are brought together by means of a screw-mechanism ; the stone, thus grasped, is crushed between them= To attain good results with the operation of litholapaxy a careful selection of cases, as well as skill in the use of the instrument, is required. Mode of Procedure. — The patient occupies the dorsal decubitus, with the pelvis somewhat elevated. The blad- der is filled moderately with sterile solution of boric acid. The lithotrite is introduced according to the rules laid down for catheterization, the operator standing upon the right side of the patient. An attempt is made to touch the stone with the tip of the closed instrument, when the blades are separated to grasp the stone. The blades of the instrument are fixed by means of a sliding arrange- ment on its handle, and the stone is crushed by means of the screw-meclianism. Xow, the individual fragments of the broken calculus are grasped separately and are crushed. Finally, the residue is converted into a fine powder by crushing. A rigid catheter is introduced and the bladder is irrigated, with the escape of sand. With the bladder moderately full the evacuation-catheter is connected ^\ ith a pump, whose activity is continued as long as fragments of stone are present in the bladder. If a rather large fragment of stone can be felt, this must be reduced further in size by means of the lithotrite. The cystoscope permits confirmation by ocular inspection of the fact that complete evacuation of the fragments has been effected. AVith a proper selection of the cases the results of litholapaxy may be admirable. Operations on the Bladder. — The bladder, situated in the true pelvis just behind its anterior wall, is attached to the pubic arch through the prostate gland and the pubovesical ligament. Beside, the organ is held in place within certain limits by the visceral layer of the pelvic fascia, by the vesico-umbilical ligaments and by the peri- OPERATIONS ON THE BLADDER. 347 toiu'um.

AMien eni])ty, the bladder is concealed behind the symphysis. A\ hen Idled, the up])er portion rises above the pelvic brim, so that the anterior wall of the bladder not covered by ])eritoneum comes to lie in immediate juxtaposition with the abdominal wall. The bladder can thus be opened above the symphysis without injury to the peritoneum if filled to the maximum. Suprapubic Cystotomy. — Opening of the bladder above the symphysis pubis. The operation is indicated : (1) In the presence of calculi and other foreign bodies in the bladder ; (2) In the presence of tumors of the bladder ; (3) In the presence of tuberculosis of the bladder ; (4) In cases of vesical hematuria ; (5) In cases of rupture of the bladder ; (6) For the removal of hypertrophied lobes of the prostate gland ; (7) For the purpose of forming a fistula ; (8) In cases of severe cystitis ; (9) As a preliminary operation in the performance of posterior catheterization. The mode of procedure is subject to various modifica- tions in accordance with the indications for its perform- ance. Three types of operation are distinguished : (1) Simple opening of the bladder for the removal of calculi and other foreign bodies ; (2j Opening of the bladder for the purpose of inider- taking endovesical manipulations (extiq)ation of tumors, etc.) ; (3) Opening of the bladder for the purpose of estab- lisliing a fistula. In all cases the bladder is distended to the maximum by the injection of fluid into its cavity, so that it rises above the level of the symphysis. If it is impossible 348 OPERATIVE SURGERY. thus to fill the bladder, the anteriDr wall of the visciis is forced into the wound by means of a concave grooved guide and incised. 1. Suprapubic Cystoiomy for Stone.-— T\\e patient occu- pies the dorsal decubitus, with the pelvis somewhat raised bv means of a pillow, and the operator stands to his right side. After the abdominal wall has been cleansed and shaved, a catheter is introduced and the bladder is irrigated until the escaping fluid is clear. Sterile fluid Fig. 208. — Suprapubic cystotomy : the anterior wall of the blarlder is exposed; near its summit is the i)oint of reflection of tte peritoneum. is now permitted to flow into the bladder through an irrigator or a sufficient quantity is injected to cause the bladder to become palpable as a tense swelling above the symphysis pubis. The catheter is removed and the penis is surrounded with a strip of gauze. The incision is made in the linea alba just al)Ove the symphysis, and is from 5 to 7 cm. long. Passing directly to the depth of the wound the fatty layer is traversed and the anterior rectus sheath or the fibrous linea alba is divided. The rectus muscles are retracted, and in the space of Retzius OPERATIoyS Oy THE BLADDKH. 349 thus exposed tlie l)la(l(U'r is palpable as a tense mass. The prevesical fat is displaced Iruni the bladder In- blunt dissection by means of two pairs of forceps, until the anterior wall of the viscus, recognizable bv the differ- ence in color and by the bundles of muscles and veins ujxm its surl'ace, is ex{x»sed (Fig. 208). Just below the transverse line of reflection of the jK'ritoneum a simple pointed tenaculum is introduced into the wall of the bladder, which is divided in the median line with a slmrp-pointed knife, in the direction of the symphysis. The margins of the wound are held apart by means of two retractors. The ojx-rator introduces the index-hnger of his left hand into the bladder, touches the stone or the foreign body, and permits the stone-forceps to follow the palmar aspect of the finger to the calcidus. The blades of the forceps are now separated, the stone grasped and removed from the wound. The wound in the wall of the bladder can be closed at once by suture. Various complicated methods of suture of the bladder have been abandoned. The wotmd in the viscus is closed by a series of interrupted catgut-sutures, including the entire thickness of the wall of the bladder, with the ex- ception of the mucous membrane. Fixation of the sutured bladder to the abdominal wall (ri/.^topexy) is not without advantage. Suture of the wall of the bladder may be omitted and the wound in the viscus be permitted to remain open. The urine is re- moved by suction and the bladder is by this means kept perfectly at rest. 2. Suprapubic Cystotomy for the Purpose of Zliderfak- ing Intravesical Manipulations. — If opening of the bladder is effected as a preliminary procedure to facilitate intra- vesical manipulations, it is best to raise the pelvis as high as possible. The preparations for the operation, and the opening of the bladder, are made in the manner already described. After the bladder has been opened a view of its interior should be possil)le. To this end the margins of the wound in the bladder are held apart by means of 350 OPERATIVE SURGERY. Plate 21.— Suprapubic Cystotomy with the Pelvis Elevated. The wouud is enlarged by the introduction of retractors and the in- terior of the bladder is rendered visible. The wall of the viscus has been provisionally attached to the skin by suture. There may be observed the mouth of the urethra, the trigone, and the entrances of the ureters. The wall of the summit of the bladder appears as a prominence above the broad speculum. retractors resembling vaginal specula, while a broad Simon speculum is introduced in the upper angle of the Avound. If, beside, the interior of the viscus is illuminated by means of an incandescent lamp, inspection is readily pos- sible and the operator may undertake a variety of manipu- lations within the cavity of the bladder (excision of tumors, control of hemorrhage, suture of deficiencies in the mucous membrane, excochleations, etc.) (Plate 21). if after extirpation of vesical tumors bleeding has been completelv controlled, the bladder may be closed by suture. After excochleation of malignant tumors, and after opera- tions upon the prostate, drainage of the bladder is the pre- feraVjle m(.>de of procedure. Bv making a transverse incision through the skin and opening the bladder in the same manner, after division of the recti muscles, general access to the interior of the viscus is possible. Suggestions have been made by a number of operators to expose the bladder throughout a greater extent by means of operations upon the bony parts. To this end Helferich resects a triangular portion of the symphysis pubis, while Bramann recommended temporary partial resection of the symphysis, and Xiehans lateral resection of the pelvis. 3. Section of the Bladder for the Purpose of Establish ing a Fisfida. — Crfsfostomi/. — In the performance of cystostomy a short longitudinal incision is made above the symphysis pubis according to the method of Poncet, and the bladder is opened in the usual manner. The Avail of the bladder is brouo:ht to the level of the skin and fixed in place by Tab. 21 r^ X St F Reichhold.

The cutaneous wound is closed in its upper por- tion, while the vesical nuicous membrane is sutured in its lower portion. The establishment of a fistula may be effected also without suture of the vesical mucous mem- brane, bv the employment of simple siphon-drainage. The curved tube may in the further course of the case be replaced by a soft catheter, which is introduced into the bladder throiio'li the wound and is permitted to remain. Operations upon the Prostate Gland, the Semi- nal Vesicles, and the Vas Deferens. — Prostatotomy. — Opening of the prostate through an incision in the peri- neum is ijidicated in the presence of abscesses and for the excochleation of tuberculous masses in the gland. After the root of the penis and the superficial transverse perineal muscle are exposed by an incision through the perineum and the connections between the sphincter ani and bulbo- cavernosus muscles are divided transversely, the anterior wall of the rectum can be separated by blunt dissection from the prostate gland and reflected toward the sacrum. Between the triangular ligament of the urethra and the rectum thus displaced the slightly convex posterior aspect of the prostate lies exposed throughout its entire extent (Fig. 210). Connected with the base of the prostate are the seminal vesicles, and by continued detachment of the rectum from the bladder the fundus of the latter will be exposed, when the seminal vesicles and the vasa deferentia will be visible in the wound. The performance of prostatotomy in the presence of an abscess is performed as follows : the patient occupies the same position as in the operation for stone, and an English catheter of large caliber is introduced into the urethra. The operator sits in front of the patient and guides the knife with his right hand, while the index-finger of the left hand is introduced into the rectum, in order that in the progress of the deep dissection the anterior wall of the rectum shall be avoided (Fig. 209). A curved in- cision 4 or 5 cm. long is made through the prerectal tissues. After division of the skin and the subcutaneous 356 OPERATIVE SURGERY. connective tissue the perineal septum is divided trans- versely and blunt dissection is made between the rectum and the urethra upward toward the prostate. When the lower pole of this organ or a portion of its posterior wall is exposed in the wound, a grooved director or a pair of forceps with closed l)lades is introduced into tlie fluctuat- ing portion, when the pus escapes through the wound. The opening is now suitably enlarged and the abscess- cavity is tamponed. If a communication exists between the abscess-cavity and the urethra, the retention of a catheter is necessary in the after-treatment. Extirpation of the Seminal Vesicles. — In extirpation of the seminal vesicles the perineal route just described appears the most desirable. The patient and the operator occupy the same positions as in the operation just con- sidered. A large perineal flap-incision is made Avhose posterior extremity on either side extends to the tuber- osities of the ischium and whose anterior l^oundary lies in front of the rectum. The mode of procedure in the depth of the w^ound is analogous to that pursued in the performance of prostatotomv. The detachment of the rectum is undertaken through a considerable extent until the seminal vesicles and the fundus of the bladder become visible on displacement of the rectum toward the sacrum. The altered seminal vesicles are j^eeled out of their sur- roundings, dissected from the fundus of the bladder, and removed. At the same time morbid collections in the prostate gland can be excised. Excisions of the Prostate ; Prostatectomy. — In cases of hypertrophy of the prostate gland removal of the enlarged middle and lateral lol^es has l^een recommended for the relief of the difficulty in urhiation and has been practised by numerous surgeons with varying success. The question whether cure is effected by removal of the pros- tatic obstruction is not as yet decided. At any rate, ad- vanced cases in which secondary changes in the wall of the bladder and of the upper urinary passages have taken place are not adapted to the operation. OPERATIONS UPON THE PROSTATE GLAND, ETC. 357 The enlarged middle lobe of the prostate, which often attains the size of a walnnt and more, may ho extirpated tln-oiigh the suprapubic incision into tiie ljhi(hler Q>{. C. Gill). The hhidder is opened above the symphysis pubis in the Usual maimer and the prominent tumor is removed with the Paquelin cautery, or the galvanoeaustic loop, or with curved scissors. . The base of the wound is cauter- ized for the control of hemorrhage, and, if necessary, the bladder is tamponed. The enlarged lateral lobes of the prostate can be only partially removed or excised, care being taken to avoid opening the urethra. In the performance of partial resec- tion adequate exposure of the body of the prostate is essential. The glanxl is exposed either with the aid of the perineal prerectal incision or through a sacral incision. The details of the first method are given on page 35e5. The sacral method of exposing the prostate has been recom- mended l)y Dittel (lateral prostatectoiny). In this mode of procedure an incision is made in the folds of the anus, the rectum is displaced laterally and in this way the pos- terior surface of the ])rostate is brought into view. The patient occupies the right lateral decubitus and an English catheter is introduced into the urethra. The incision be- gins at the apex of the coccyx, passes in the middle line to the posterior margin of the anus, which it surrounds npon the right side, and terminates in the perineal raphe in front of the amis. The operator gains entrance into the ischiorectal fossa, and separates the rectum by blunt dissec- tion from the ])rostate, so that the right lateral lobe of the latter and, if the dissection be continued, the entire poste- rior aspect are exposed to view. Wedge-shaped portions of the gland are excised on either side. Dittel recommends that so much of the gland be removed that only sufficient remains to surround the urethra. The removal of the coc- cyx is calculated to enlarge the field of operation. Resection and Extirpation of the Vas Deferens. — Resec- tion of the vas deferens in its contniuity has been recom- mended recently in the treatment of hypertrophy of the 358 OPERATIVE SURGERY. prostate gland, and has been performed in numerous cases. The vas deferens is palpable through the skin as a round, firm strand, and it may thus be separated from the re- maining structures of the spermatic cord. The cutaneous incision for the isolation of the vas deferens, 3 or 4 cm. long, may be made either in front of the external inguinal ring, or at the neck of the scrotum. The structures form- ing the spermatic cord are forced out of the Avound, the vas deferens is isolated by touch and a portion from 2 to 4 cm. long is excised 'svith scissors. Removal of the vas deferens in connection with the testicle becomes necessary when in the presence of tuberculosis of the epididymis the vas deferens also is involved in the disease. Under these conditions the incision for exposure of the testicle, which passes longitudinally over the scrotum, is extended upward and outward over the inguinal canal. Throughout the range of the incision the skin and the anterior boundary of the inguinal canal are divided so that the vas deferens is exposed in its course through this canal, and is thus rendered accessible to surgical removal. The pelvic por- tion of the vas deferens would be accessible by this means only after extended detachment of the peritoneum, entail- ing injury of disproportionate degree. This portion of the duct is therefore to be reached by the perineal route or with the aid of an incision such as I)ittel has reconnnended in the performance of lateral prostatectomy. Biingner recommended, in place of extirpation, divuhlon of the vas deferens. The duct is isolated and exposed throughout a considerable extent by gradually increased traction. AVith careful manipulation of this kind four- fifths of tiie entire duct may be removed. Extirpation of the Testicle. Castration. — The indica- tions for this operation consist in tlie presence of neo- plasms of the testicle and tuberculosis of the epididymis. A new indication for castration is afforded by hypertrophy of tlie prostate. Tlie cutaneous incision is always made longitudmally over the greatest convexity of the tumor. In making this incision the operator grasj^s the scrotum OPERATIOXS UPOy THE PROSTATE GLAXD, ETC 359 with his left hand in such a manner that the overlying skin is made tense. If the skin is involved in the disease- process throughout a circumscril)ed area (fnjm extension of a neoplasm, or the formation of a tuberculous fistula), the diseased structure is included between the incisions and is removed in conjunction with the testicle. The incisions are made threuijch the skin and the dartos down to the tunica vaginalis and the testicle, with its covenngs, is freed from its bed by l)luut dissection, so that it remains in connection with the body only througli tlie intermedia- tion of the spermatic cord. By traction on the cord its constituent structures are more clearly brought into view. The vas deferens is isolated and ligated. The remaining structures of the spermatic cord are ligated en masse in two or three segments. The cord is then divided trans- versely on the distal side of the ligatures, which are cut short. The stump of the cord retracts into the depth of the wound, and tlie cutaneous wound is closed by suture. Operation for Hydrocele. — Hydrocele is treated in a palliative way by simple puncture and in a radical Avay by laying open the tunica vaginalis and excising it. Punct- ure of a hydrocele is made in accordance with the rules that govern the making of punctures in general. The operator must, however, be assured of the position of the testicle, in order to avoid injury of this organ in intro- ducing the trocar. The scrotum is grasped firmly with the supinated left hand and made tense. The introduc- tion of the trocar is made upward through the anterior wall close to the fundus of the scrotum at a point where no vein is visible through the skin. At first the fluid is expelled in a continuous stream. Later the escape must be facilitated l^y alteration in the position of the cannula and by kneading movements of the scrotum. The injec- tion through the cannula of from 5 to 10 gm. of LugoPs solution, in conjunction with the puncture, is a favorite mode of radical operation for hydrocele. The procedure, however, is extremely painful and with regard to the cer- tainty of the result stands behind radical incision. 360 OPERATIVE SURGERY. Radical Incision by the Method of Vollinann, — The scrotum is grasped firmly and made tense with the left hand and an incision is made longitudinally over the greatest convexity of the tumor almost up to the fundus. With careful dissection the incision is carried down to the tunica vaginalis, which is divided in the direction and throughout the extent of the cutaneous incision. After the fluid has escaped, the tunica vaginalis is united to the skin by a row of sutures and a strip of gauze is introduced into the cavity that remains. The process of healing often occupies a considerable period of time. Radioed Operedion by the Methoel of Bergnumn. — Radi- cal operation by the method of Bergmann is followed by recovery within a short time, by reason of the fact that the wound-conditions render possible union by primary intention. A cutaneous incision is made in the manner just described. Before the sac of the hydrocele is opened, an endeavor is made to free it from the overlying skin throughout a considerable extent. After this has been adequately effected the sac is opened as in the operation of Volkmann. After the fluid has escaped the opera- tor grasps the margins of the incision through the tunica vaginalis and separates this from the testicle on either side, almost to the point of reflection. After this detachment has been thoroughly effected the freed parietal layer of the tunica vaoinalis is excised. The maro^ins of the in- cision in the skin are accurately approximated by suture over the testicle, which is dropped back into the wound. Operation for Phimosis. — Operations for phimosis in- clude surgical procedures of various kinds by means of which congenital or acquired narrowing of the prepuce is removed. In performing the operation either the prepuce is divided longitudinally from its orifice to the glans [in- cinion) or the entire prepuce is removed [circumcisioii). By the first of these methods the incision is made in the middle line of the d(u*sal surface, a grooved director, with its concavity directed upward, being introduced into the orifice between the prepuce and the glans. The two OPERATIONS UPON THE PROSTATE GLAND, ETC. 361 layers of tlie prepuce are divided over the director with a single stroke of the scissors almost up to the corona glandis. After the division has been effected the prepuce must be readily retractable. Over the glans throughout the extent of the wound the mucous membrane of the ])repuce is united with the skin by means of a series of interrupted sutures, or of a continuous suture. Circumcision may be effected in various ways. The prepuce may be drawn forward as far as possible and be Operation for Shortened Frenum. Fig. -m. Fig. 212. Fig. 211. — Transverse division of the frenum. Fig. 212. — Union at right angles to the direction of the division, divided just in front of the glans, after which the margins of the outer and inner layers of the prepuce are united by suture. In another method of circumcision the usual dorsal incision is first made, after which portions of the prepuce on either side of the incision are removed with scissors close to the point of reflection on the glans. Throuo;hout the entire extent of the wound the skin is united with the inner layer of the prepuce. Operation for Shortened Frenum. — Congenital shortness of the frenum, with a normal caliber of the prepuce, is 362 OPERATIVE SURGERY. attended with numerous discomforts (pain in coitus, fre- quent laceration, hemorrhage). Simple transverse division of the band is not to be recommended on account of the hemorrliage that follows. Division with the Paquelin cauterv secures immunity from the hemorrhage, but a considerable time is occupied in the healing of the wound. Functionally good results, Avith the possibility of securing union bv primary intention, are yielded by the following minor plastic operation. The frenum is divided with a single stroke of the scis- sors to such a depth that the prepuce can be retracted to a maximum degree without tension. The small wound thus made is united at a right angle to the direction of the incision (Figs. 211 and 212). Amputation of the Penis. — Malignant neoplasms con- stitute the exclusive indication for amputation of the penis. This may be practised through the pendulous portion at a selected level by means of a circular incision. Under certain conditions the deeper portions of the member, the roots of the cavernous bodies, must be removed by ope- ration. In all cases, after ablation of the parts, the uretlira must be suitably situated and fixed in the wound. In amputating the penis through the pendulous portion digital compression is exercised, while a circular incision is made transversely. The skin is, after division, re- tracted, when the operator divides the cavernous bodies transversely Avith an amputation-knife, cutting from the dorsal aspect toward the urethra. When the urethra is reached it is dissected free for a short distance toward the periphery and is divided transversely 2 cm. in advance of the line of incision through the cavernous bodies. The urethra is snipped through its inferior sur- face with a single stroke of the scissors, spread upon the wound and united by its free border with the margin of the skin by means of a series of sutures. In amputating the penis in conjunction with its perineal connections the scotum is divided in a sagittal direction. In the gaping wound the roots of the cavern- OPERATIONS UPON THE PROSTATE GLAND, ETC. 363 ous bodies, with their attaclimcnts to tlic })n])i(' Imncs, are roadilv ('.\j)()sc(l. The urethra is (livi(lear in the wound u])on one side the groove of Poupart's ligament and upon tlu; other side the outer border of the rectus muscle, together with the muscular plate formed by the divided internal oblicpie and transversalis muscles. This muscular layer is separ- ated by blunt dissection from the subserous tissues, as well as from the aponeurosis of the external oblique, so that it is rendered sufficiently movable to be brought down to Poupart's ligament. The muscular plate named is attached to the posterior border of Poupart's ligament by sutures (Plate 23, III). The sutures on the pubic bone include also the external border of the rectus muscle. In this way a posterior muscular wall of sufficient resistance is formed, in which lies the newly created narrow internal inguinal ring. The spermatic cord is })laced upon this muscular layer, and over it the aponeurosis of the external oblique is closed by suture except at its lower angle, wOiich constitutes the new external inguinal ring (Plate 23, IV). The inguinal canal thus formed is, after healing has taken place, so resistant that the use of a supporting truss can be dispensed with. In Kocher's radical operation for inguinal hernia (displacement- method) the cutaneous incision is made as in Bassini's operation, although the aponeurosis of the external ol)lique is not divided, l)ut slit to the outer side of the internal inguinal ring. Through this opening a i)air of forceps is introduced and j)assed through the inguinal canal to tlie ex- ternal inguinal ring. The apex of the isolated hernial sac is grasped, and drawn outward through tlie small opening. The hernial sac is drawn so that it appears sharply l)ent hackward at the internal inguinal ring. The portion of the sac lying within tlie abdominal wall is surroundi'd and strongly ligated. The hase of the sac thus folded together is attached to the outer surface of the aponeurosis of the external oblique by means of deep sutures, and the remainder is removed. Radical Operation for Femoral Hernia. The Femoral Cnxnl. — The interval between the internal and the ex- ternal femoral ring, whicli constitutes the path for certain varieties of hernia, is known as the femoral canal. Under normal conditions, 24 370 OPEBATIVE SURGERY. Plate 23.— Bassini's Operation for Inguinal Hernia. III. The muscular layer of the internal oblique and transversalis is attached by suture to the inner border of Poupart's ligament. In this way the internal inguinal ring and the posterior wall of the inguinal canal are formed anew. IV. The aponeurosis of the external oblique is united over the sper- matic cord except in the situation of the new external inguinal ring. however, this canal is not present as such. The inner orifice of the canal (internal crural ring) lies at the inner angle of the opening for the femoral vessels, between Poupart's ligament and the horizontal ramus of the pubis. Thespace is bounded within by the free border of Gimberuat's ligament (fan-shaped attachment of Poupart's ligament to the tubercle of the pubic bone) and without by the large vessels and the crural vein. The outer orifice of the crural canal corresponds with the loose connec- tive tissue of the fascia lata (foramen ovale) through which the saphenous vein passes to enter into the femoral. The tendinous boundary of this opening has its concavity directed toward the middle line and is known as the falciform process. A femoral hernia, after passing the internal craral ring, enters a space whose floor is formed by the pectineal fascia, which is bounded internally by Gimber- nat's ligament, externally by the crural vessels, and in Avhich for a short distance the upper continuation of the ftlciform process forms a resistant cover. If the free border of this be passed, the hernia can push before it the less resistant lamina cribrosa and in this way it reaches the exterior through the foramen ovale. The coverings of a femoral hernia are thus fewer and thinner than those of an inguinal hernia. The hernial sac may under circum- stances, in emaciated subjects, lie just beneath the subcu- taneous connective tissue. For this reason, in making the cutaneous incision, especially in further dissection at a depth, great care will be required. In general the radical operation consists, after making a cutaneous incision, in isolation and opening of the liernial sac. Then follow reposition of the hernial contents and ligature of the neck of the sac, with or without torsion. By closure of the hernial opening through suture the recurrence of the dis- order is to be prevented. Radical operation for the relief of femoral hernia is rendered difficult by the fact that the Tnl^ 9* fll. I\'. LUh.

Mode of Fcrforiiiiiif/ the Radical Operaiion for Fe moral Hernia. — A cutaneous incision is made by the method of Bassini, vertically over the greatest convexity of the tumor. The outer surface of the hernial sac and the fas- cia to the peripheral side of the swelling are exposed. The body and the neck of the sac are isolated to a point above the level of the internal crural ring. Isolation of the hernial sac upon its outer side, where it is in close relation with the femoral vein, nuist be undertaken with great care. The hernial sac is opened and its contents replaced after separation of adhesions. The body of the hernial sac is eh^vated, twisted, and ligated with a thread passed around its neck. The sac is divided transversely beyond the ligature. After replacement of the stump the hernial ojiening, the plica falciformis, the internal open- ing, with Giml)ernat's ligament, and the aponeurosis over the pectineal crest are sufficiently exposed. Suture begins close to the pubic tubercle and the sutures include the pectineal aponeurosis and the posterior inferior portion of the internal opening. In the further course of the opera- tion the border of the falciform process is united with the pectineal fascia. After all of the sutures have been introduced they are tied, beginning with the innermost and uppermost. The line of suture pursues the course of an oblique C. Fabricius closes the hernial opening by suture in cases of femoral hernia after the fat as well as the lymphatic glands present in the fem- oral canal are removed in such a way that Poupart's ligament is relaxed and is attached by periosteal sutures to the horizontal branch of the pubic bone. Umbilical Hernia, Radical Operation. Operation for In- carcerated Omphalocele. — The usual procedure consisted until recently in closure of the hernial opening by suture after opening the hernial tumor and replacement of the 372 OPERATIVE SURGERY. intestine. Greater security against the recurrence of the hernia and a more thoroiigii inspection during the opera- tion are aiforded by excision of the umbilical ring {omph- aledorni/, Condamin, Bruns). The umbilical region is surrounded by two elliptic incisions, each of which ex- tends to the inner l)order of the rectus muscle and opens the abdominal cavity on either side of the hernial ring, so that the entire hernial tumor, together with the neck of the hernial sac, is removed. If, in addition, a portion of the sac is divided from the margin of the Avound through the hernial opening, the entire contents of the hernia are exposed to view. In this way satisfactoiy scrutiny of the conditions present is possible, inasmuch as the abdominal viscera are rendered visible, both prior to the entrance into the hernia, as well as within the hernial sac. Adhe- sions that may be present are separated, and any existing strangulation can be freed in the open wound. After re- placement of the intestines the abdominal Avound is care- fully approximated by interrupted sutures in three layers, the first including the serous membrane, the second the recti muscles and sheaths, and the third the skin. Ligation of the Iliac Artery. — At the level of the fourth lumbar vertebra the aorta divides into the two iliac arte- ries, each of which in turn divides at the sacro-iliac articu- lation into two branches, the external and internal iliac arteries. The external iliac arters', the abdominal por- tion of the femoral, passes along the outer side of the corresponding vein along the psoas muscle to the opening beneath Poupart's ligament for the vessels. The internal iliac artery, also known as the hypogastric, passes from the sacro-iliac symphysis down into the pelvis, to supply the organs of this cavity, as well as the gluteal muscles and the genitalia, with blood. Ligation of the External Iliac Artery. — The artery- is exposed in the subserous space just prior to its entrance into the opening for the vessels. The cutaneous incision is made parallel with, and over the middle of, Poupart's ligament, and the fascia of the external obliq^ue muscle, OPERATIOSS UPON THE PROSTATE GLAND, ETC. 373 the fibers of the internal ol^licjue and transversalis are divided in thedireetion, and throii^rhout the extent, of this ineision. Alter divi.^ion of the transversalis faseia the subserous fat and the peritoneum are ex})osed to view. The peritoneum is se})arate(l by blunt disseetion from Poupart's li*iament and the pelvie margin, after whieh the external iliae vessels surrounded by loose connective tissue become visible upon the floor of the wound. The artery (the vein lies to its inner side) is isolated Ijy l)lunt disseetion with the aid of two anatomic forceps (Plate 24). In ligating the internal iliac artery the cutaneous in- cision passes from the apex of the last rib vertically down- ward to the crest of the ilium and along this almost to the anterior superior iliac spine. The layers of the abdominal wall and the transversalis fascia are divided, the peritoneum separated by blunt dissection from the iliac fossa and displaced toward the median line by means of broad spatula? or the palm of the hand. Between the iliac and psoas muscles the external iliac artery is visible and can be followed in a proximal direction as far as the sacro-iliac symphysis, where the internal iliac artery is accessible as it branches off toward the pelvis and can be isolated for ligature. The vein lies to the inner side of the artery. The mode of procedure just described serves also for exposing the common iliac artery. The manner of exposing the iliac vessels constitutes in general the mode of procedure in accordance with which the structures of the subserous space are reached. The incision for ligation of the internal iliac artery exposes the kidney and the ureter in its course. In the same way it is possible, with conservation of the peritoneum, to evacu- ate accumulations of ]nis in the subserous space (psoas abscess, paratyphlitic abscess, parametric abscess). If after opening the abdominal cavity by celiotomy the parietal peritoneum upon the posterior wall of the abdo- men is divided and in this way the retroperitoneal space is exposed, the procedure is designated transperitoneal ex- posure of the iliac artery, of the kidney, of the ureter, 374 OPERATIVE SURGERY.

There are divided the aponeurosis of the external oblique muscle (Q.e.), the fibers of the internal oblique {Q-i.), and the transversalis fascia (F.t.)\ the peritoneum (P) is separated by blunt dissection and raised up ; the iliac artery and vein are exposed in the subserous space. etc. Under these conditions the peritoneum must be divided at two corresponding points on the anterior and the posterior abdominal walL Operations on the Kidneys. — Operations on the kidneys may be undertaken : 1. For the purpose of opening the kidney by incision — nephrotomy ; 2. For the removal of the totally diseased kidney — nephrectomy ; 3. For fixation of a movable kidney — nepjhropexy ; 4. For the exsection of portions of the kidney — resec- tion of the kidney. Nephrotomy and Nephrectomy. — Nephrotomy is indi- cated in the presence of — 1, simple pyonephrosis ; 2, stones in the pelvis of the kidney, if sufficiently function- ally active parenchyma remain ; 3, severe renal hematuria; 4, hydronephrosis. Nephrectomy is indicated in the presence of: 1, severe pyonephrosis, if the kidney is transformed into a series of pus-cavities (calculosis, tuberculosis of the kidney) ; 2, in- juries of the kidney (rupture, laceration) ; 3, tumors of the kidney ; 4, incurable ureteral fistulse. For exposure of the kidney the patient is placed upon the healthy side of his }x)dy over a pillow. The cuta- neous incision begins at the twelfth rib and passes thence vertically downward toward the crest of the ilium and along this almost to the anterior superior spine. Skin, fat, lumbodorsal fascia, the fibers of the latissimus dorsi are divided, in order that, after division of the deep layer of the fascia, the quadratus lumborum and, in the anterior portion of the wound, the triplicate layer of the abdominal muscles, may be divided.

OPERATIONS ON THE KIDNEYS. 375 also liiis \wvn j)mss(>(1 tlio fiitty ca[).sulc of the kidney is exposed tliroiiohont u suHieient extent. This eai).sule is divided and the kichiey is removed from its bed by bhmt disseetion with tlie tinger until the organ, eompletely freed at all points with the exeeption of its hilus, can be brought by traction to the level of the wound. For exploration of tlie pelvis of the kidney, for the removal of stones from the pelvis, et<;., the kidney is opened from its eonvex border. An incision is made u])on the convexity, through the renal parenchyma, down to the pelvis of the kidney, large enough to permit the introduction of the index-finger, with which the pelvis is examined. If necessary, this incision may be extended toward the poles of the organ to a maximum degree until the kidney can be separated in two halves. This procedure is carried out with digital compression of the large vessels at the hilus of the kidney. If the conditions are so constituted that primary union can take place, the wound in the kidney is closed by deep and superficial in- terrupted catgut sutures, the organ dropped into place, and the cutaneous wound closed, except for a small opening for a drainage-tube. Provisional suture of the wound in the kidney for the control of hemorrhage may also be under- taken if in immediate conjunction with an exploratory incision the removal of the entire organ is determined upon. After extirpation of the kidney the large vessels at its hilus must be exposed and carefully ligated. If possible, the kidney is drawn forward and the artery and the vein are isolated at the hilus (Fig. 216). If this is not possible, the operator grasps the hilus of the organ with the thumb and index-finger of the left hand and witli the guidance of this hand a])plies a clamp-forceps around the entire pedicle. The pedicle is divided beyond the grasp of the forceps with scissors and ligated en masse upon the proximal side. The large vessels exposed in the transverse incision are further isolated and ligated separately. The large wound-cavity is closed after perfect control 1^76 OPERATIVE SUHGERY. of hemorrhage, drained, and the wound closed by sutures in tiers (muscles, fascia, skin). To effect operative fixation of a movable kidney (nephro- pexy, nephrorrhaphy) the organ is exposed in the usual manner, the sutures (ten or twehe) for the fixation of the organ being passed deeply through its parenchyma and placed in the upper angle of the cutaneous incision on % ■"'TV;''. I'"l * m Fig. 216. — Lumbar incision : the kidney is brought out of the wound in the abdominal wall and the structures of the hilus of the organ are isolated and exposed for ligature. either side and tied. In this manner the kidney is suitably located and fastened. The method of retroperitoneal ex- posure of the kidney described affords as a rule sufficient access to the organ. In the presence, howeyer, of large diffusely adherent tumors of tlie kidney, or in the case of adipose indiyiduals, it may be necessary, to afford greater accessibility, to make from the middle of the lumbar in- cision a transyerse incision passing toward the umbilicus. OPERATIONS ON THE KIDNEYS. Z11 Bardeiiheuer recoininonds the so-called (rajj-door incision. From the upi)or and lower extifinitics of the vertical longitudinal incision i)assinK from the costal arch to tlu- middle ol" the crest of the ilium transverse incisions are made aloui^ tlu- rib and the iliac crest. IJardenheuer makes three forms of trap-door incision, an anterior, | , a posterior, ^^, and a two-sided one, ~i~ . Ill contradistinction from the retroperitoneal method described is the transpe;ntoneal method for exposing the kidney. In this latter operation tlie a1)d()minal cavity is opened in the usnal manner in the linea alba, the peri- tonenni over the kidney is divided, and the organ is enucleated out of its bed. The retroperitoneal method has, on the (Ulier hand, the advantage of permitting, iii conjunction with an exploratory procedure, of the estab- lishment of a renal fistula, of the drainage of an abscess of the kidney under favorable conditions, as well as total removal of the entire organ. Operations on the Ureters. — The ureter passes from the kidney on either side in the subserous space just behind the peritoneum to the fundus of the bladder. In its upper portion it lies upon the psoas muscle, crossing at its entrance into the pelvis the point of division of the com- mon iliac artery and entering the pelvis in a direction for- ward and inward to reacli the base of the bladder. Most commonly injuries of the ureter in the course of opera- tions furnish the indication for operations upon this struct- ure ; less commonly impaction of stones in the ureter, .occlusion of the lower extremity of the ureter from the presence of a neoplasm, or kinking of the ureter in cases of hydronephrosis. Of operations tliere have been performed : linear open- ing of the ureter for delivery of a stone, with subsecjuent suture of the incision (ureteroUthofomi/) ; the displace- ment of a stone present along the ureter into the ])elvis of the kidney ; and, finally, digital attrition of soft stones without opening the ureter. In the presence of injuries of the ureter, restoration of the lumen of the tube by suture of the stumps or grafting of the central stump of the ureter into a neiffliboriup; oroan mav be undertaken to 378 OPERATIVE SURGERY. effect closure of ureteral fistuhe. With this eud in view the ureter has been united w ith the bowel {uretero-enter- ostomy), with the ureter of tlie opposite side (uretcro- iireterostomy) , and with a new portion of the bladder (iiretero-neocystostomy). Anastomosis of the ureter with -LUUi'Jf J>-J'-#---J- -■^. Fig. 217. — Invagination-suture of the stumps of the divided ureter. the bowel has also been undertaken for the correction of ectopy of the bladder (Maydl). Circular union of the transversely or obliquely divided stumps of the ureter has the disadvantage, in view of the narrow caliber of the ureter, of being followed by such contraction of the cicatrix as to result in narrowing of the lumen of the tube. OPEBATIOyS UPON THE RECTUM AND ANUS. 379 For this reason the invagiiuition-.siiturc of A an Hook is to 1)1' prcicrrctl. The free end of the peripheral stump is closed l)y a ligature, 2.5 mm. below whieh a longitudinal incision is made through the thickness of the wall oi" the uretei'. The central stump is caught with a catgut suture, the ends of which are carried by means of a needle through the longitudinal incision in the ])eripheral stump, the needle being further. passed through the opposite wall of this stump. By gentle traction on the suture the centml stump of the ureter is drawn through the slit in the peri])heral portion, and fastened in position by knot- tino- the thread in this situation. A few additional sutures on the outer side insure contiguity of the stumps (Fig. 217). In the practice of implantation of the ureter by the method of l^iidinger and M'itzel a normal canal is formed in which the ureter is contained (oblique fistula), thus most nearly imitatino; the natural mode of entrance of the ureter. The divided ureter is implanted in the wall of the selected organ in the same manner as is the rubber tube in WitzeFs operation of gastrostomy, and is fixed in position by suture. For exposure of the upper portions of the ureter the lumbar incision, as for neph- rectomy, may be made advantageously. The pelvic por- tion of the ureter in the male is accessible through the sacral route after enucleation of the coccyx and avoidance of the rectum. Operations upon the Rectum and the Anus. — Amputation and Resection of the Rectum. — Operations for the removal of tumors of the rectum will vary with the seat and the extent of the morbid process. Circumscribed or pedunculated tumors are surrounded by incisions at their base, and severed through healthy tissue, the wound created being closed by suture. It is difficult in the treat- ment of cases of this kind to expose sufficiently the field of operation. For more deeply seated tumors, in the re- gion of the anus, it is sufficient to distend this portion of the bowel by means of retractors or suitable specula. 380 OPERATIVE SURGERY. Tiiiiiors seated high up require as a preliuiinarv operation linear division of the sphincter^ which is practised on the anterior and posterior aspects along the line of the raphe, with marked retraction of the margins of the wound, and renders accessible to the knife the portions of the rectal mucous membrane above tlie sphincter. The anterior wall of the rectum can be reached with the aid of a pre- rectal incision by separation of the rectum from the urethra (see Prostatotomy). By this means the entire thickness of a circumscribed portion of the wall of the rectum can be resected and the defect be closed by suture. If the neoplasm involve the entire periphery of the lowest portion of the rectum a circular incision is made around the anus and tlie lower extremity of the rectum is freed from its surroundings. The rectum is then divided trans- versely upon the proximal side of the neoplasm. The wound is so adjusted that the stump of the rectum, brought to the level of the surface, is fixed to the skin by sutures passing through all the layers of the wall of the bowel. This method of amputation has a limited field of applica- tion. If the upper border of the tumor can he reached with the palpating finger, its removal by the method de- tailed can be technically carried out ; but isolation of the rectum in its upper portions and access to the sigmoid flexure are quite impossible by this mode of procedure. The cutaneous wound allows of limited access, so that certainty in operation, especially control of hemorrhage in the higher portions of the wound, encounters irremovable obstacles. Resection of the rectum^ with union of the stumps of the intestine, l)y tlie method described, is difficult even if access is afforded by anterior and posterior incisions througli the raphe, also when the tumor is deeply seated, and entirely impossible if this be situated in tlie upper portion of the rectum. The limits of operability of tumors of the rectum were enlarged materially with atteni])ts, on Kraske's sugges- tion, to expose the rectum sufficiently and also in its OPERATIOSS UPON Till': IlhVTUM AND ANUS. 381 liiiiluT jxuMion tliroiinh tlic sacral route It is possible by tills mode ol' priK'ediire to isolate tiie reetiiin even to its intraperitonetil portion and to praclise resections of this j)or- tion of the l)()\vel in its continuity, w ith an adeijuate lield of (yperation. The rectum is reached from the posterior aspect after division of the sacrotuherous and sacrospinous liiraments through the wide interval on either side between the margin of the sacrum,and the tuberosity of the ischium. The accessibility is increased by removal of a portion of the mariiin of the sacrum with a chisel. Mode of Kffivthig Sdcral Krposurc of the Rectum (HochenejriJ:). — The patient occupies the left lateral decu- bitus with the lower extremities flexed at the hips and the knees and the operator standing back of the patient. The cutaneous incision begins at the middle of the left sacro-iliac symphysis and passes over the middle line in an arc whose convexity is directed toward the right and terminates below the apex of the coccyx ; or, if the anal portion also is to be removed, it surrounds the anus ellip- tical 1 v. The incision is deepened down to the bone. The soft parts are retained in connection with the skin and are dissected from the bone so that the left half of the sacrum and the coccyx are exposed in the wound. After enuclea- tion of the coccyx access to the rectum will be already relatively free and it becomes considerably greater after division of the attachments of the sacrotuherous and sacro- spinous ligaments. The extensive field of operation thus exposed ])ermits of careful scrutiny with regard to the extent and limits of the tumor, and even of the higher portions of the rectum, not accessible through the usual modes of procedure. Further extension of the field of o]ieration can be effected by chiselling the left margin of the sacrum. After exposure of the rectum the second step of the operation — that is, isolation of the tumor beyond its limits — is undertaken. The rectum is separated from its sur- roundings by blunt dissection and the visible vessels are ligated in the wound. If high amputation of the rectum 382 OPERATIVE SURGERY. is to be performed, the stump of the bowel is brought clown and fastened to the skin in the upper angle of the wound (sacral preternatural anus). This procedure is indicated when the anal portion is involved in the new- growth and must be removed in connection therewith. If, on the other hand, the anal portion is healthy, the tumor being seated in the middle portion of the rectum, the bowel on either side of the morbid process is isolated by blunt dissection into healthy tissue, ligated and re- moved by resection. The two stumps of the intestine are united either primarily tln'oughout their entire extent, or sutured only partially, so that a provisional artificial anus is formed. This forms a mural fistula, Avhich may either close spontaneously or be closed after a time by a plastic operation. In introducing the sutures, both stumps must be approximated without any tension. In the isokition of tumors seated high up it is often necessary to open the peritoneum of the vesicorectal cul-de-sac. The proximal stump of the rectum is brought into the wound for the formation of an artificial anus or for suture and the ante- rior lip of the peritoneal wound is united at a suitable level with the serous layer of the intestine, so that the abdominal cavity is walled off' from the AAound. After the introduction of circular intestinal sutures a large drainage-tube is introduced tlirough the anus into the rectum beyond the line of suture. Operations for Rectal Fistula. — Rectal fistula can be made to heal by division of the fistulous tract and the conversion of the tubular ulcer into an open wound. In the operation for complete fistula a slender probe is intro- duced through the external fistulous opening, Avhile the index-finger "of tlie left hand is applied to the internal opening, which often is appreciable as a loss of substance. The probe is thus passed through tlie tract and enters the lumen of the bowel. A grooved director may be readily passed through the fistula by the side of tlie probe into the rectum and its extremity brought out through the anus. The soft parts covering the fistula thus come to lie OPlJRATrONS UPON TlIK RECTUM AND ANUS. 383 upon the director, upon wliicli tlicy are divided with the knil'e. lly the iiitrodiietioii oi" teiiacuhi niter division of the tissues the eharacter of the lining of the fistulous tract ean he rendered visible. As a rule, the wound is ])er- mitted to heal hy <»;ranulation, although after extirj)ation of the entire fistulous })assage the wound can be closed completely by suture. Ineoni])lete fistuhe nfust be converted into complete Hstuhe before being divided. In the presence of an in- complete external fistula the grooved (lire(;tor is intro- duced and pushed into the rectum through the deepest portion of the fistula. Division of the fistula thus made complete is effected in the manner (lescril)ed. In the presence of an incomplete internal fistula, with its open- ing upon the mucous membrane of the rectum the sound or the grooved director is introduced from the rectum toward the skin. When the head of the probe is felt beneath the skin an incision is made down npon it and the complete fistula thus established is divided in the manner described. In the presence of extensive fistulous formations it becomes necessary to follow the manifold ramifs'ing passages often present and to open them adequately. Operation for Hemorrhoids. — Dilatations of the external hemorrhoidal veins do not require operatives treatment. Operation is indicated only in those cases of dilatation of tli(,' internal hemorrhoidal veins, with consecutive changes in the mucous membrane, in which prolapse of the mucous membrane of the rectum has taken place, Avhich makes itself apparent either only npon increased abdominal pressure or habitually as a result of this influence. The prolapsed masses of mucous membrane are either destroyed with the actual cautery, or subjected to atrophy through the elastic ligature, or excised by a bloody operation. Caufeiizdtiou. — The patient occupies the position as in the operation for stone, or the lateral decubitus. By means of digital dilatation of the anus the hemorrhoidal masses are exposed to view. They are grasped in seg- 384 OPERATIVE SURGERY. ments with a clanip-forceps and their base is surrounded by Langenbeck's flat forceps. The tumor lying upon the broad ivory plate of the forceps is totally destroyed with the tip of the Paquelin cautery^ after which the forceps is carefully removed. In the same manner the swellings throughout the entire circumference of the rectum are destroyed. EUiatic Ligature. — The patient occupies the lateral decubitus. By means of a clamp polyp-forceps the ex- truded mass of mucous membrane is grasped at its base and brought forward. The elastic ligature is passed around the neck of the nodule behind the forceps and tightened and the nodule fixed by means of a silk thread tied around it. In this way the whole series of folds is included in three or four parts and ligated. The necrotic nodules are thrown off* in the course of a week. Excision may l)e practised upon each nodule individ- uallv, or a circular incision is made through the skin around the anus and also through the mucous membrane of the rectum above the level of the nodules. The cylin- der of mucous membrane, together with the dilated veins, is dissected free from the sphincter and the margin of the mucous meml)rane is united by suture with the skin at the anus. Operation for Atresia of the Anus. — The incision is made in the perineal raphe from the apex of the coccyx to the root of the scrotum (posterior commissure). The operator advances into the depth layer by layer, always keeping strictly in the middle line. As a rule, the bluish- colorerl cul-de-sac of the rectum is soon reached, and it is incised in the direction of the cutaneous incision. After the meconium has been discharged the bowel is united throughout its entire periphery to the skin by sutures pass- ing through the entire thickness of the wall of the intes- tine. If the cul-de-sac be situated high up, an effort should 1)6 made to reach the rectum by the sacral route.

D., rrofessor of Physiology in the Johns Hopkins University, Baltimore, Md. One handsome octavo volume of 1052 pages, fully illustrated. Prices : Cloth, ^6.00 net; Sheep or Half- Morocco, $7.00 net. This work is the most notable attempt yet made in America to combine in ■Mie volume the entire subject of Human Physiulogj' by well-known teachers who have given especial study to that part of the subject upon which they write. The completed work represents the present status of the science of Physiology, particularly from the standpoint of the student of medicine and of the medical practitioner. The collaboration of several teachers in the preparation of an elementary text- book of physiology is unusual, the almost invariable rule heretofore having been for a single author to write the entire book. One of the advantages to be derived from this collaboration method is that the more limited literature necessary for consultation by each author has enabled him to base his elementary account upon a compreliensive knowledge of the subject assigned to him; another, and perhaps the most important, advantage is that the student gains the point of view of a number of teachers. In a measure he reaps the same benefit as would be obtained by following courses of instruction under different teachers. The different standpoints assiimed, and the differences in emphasis laid upon the various lines of procedure, chemical, physical, and anatomical, should give the student a better insight into the methods of the science as it exists to-day. The work will also be found useful to many medical practitioners who may wish to keep in touch with the development of modern physiology. The main divisions of the subject-matter are as follows : General Physiology of Muscle and Nerve — Secretion — Chemistry of Digestion and Nutrition — Movements of the Alimentary Canal, Bladder, and Ureter — Blood and Lymph — Circulation — Respiration — Animal Heat — Central Nervous System — Special Senses — Special Muscular Mechanisms — Reproduction — Chemistry of the Animal Body.

D., Professor of the Practice of Medicine and of Clinical Medicine in the Jefferson Medical College. One handsome octavo volume of 1326 pages. Illustrated. Prices: Cloth, ^7.00 net; Sheep or Half- Morocco, $8.00 net. The arrangement of this volume has been based, so far as possible, upon modern pathologic doctrines, beginning with the intoxications, and following with infections, diseases due to internal parasites, diseases of undetermined origin, and finally the disorders of the several bodily systems — digestive, re- spiratory, circulatory, renal, nervous, and cutaneous. It was thought proper to include also a consideration of the disorders of pregnancy. The list of contributors comprises the names of many who have acquired dis- tinction as practitioners and teachers of practice, of clinical medicine, and of the specialties. COXTRIBUTORS : Dr. I. E.

The articles, with two exceptions, are the contributions of American writers. Written from the standpoint of the practitioner, the aim of the work is to facili- tate the application of knowledge to the prevention, the cure, and the allevia- tion of disease. The endeavor throughout has been to conform to the title of the book— Applied Therapeutics— to ^indicate the course of treatment to be pursued at the bedside, rather than to name a list of drugs that have been used at one time or another. While the scientific superiority and the practical desirability of the metric system of weights and measures is admitted, it has not been deemed best to discard entirely the older system of figures, so that both sets have been given where occasion demanded.

CATALOGUE OF MEDICAL WORKS. 5 For Sale by Subscription. AN AMERICAN TEXT-BOOK OF OBSTETRICS. Edited by Richard C. Norris, M. D. ; Art Editor, Robert L. Dickinson, M. D. One handsome octavo volume of over looo pages, with nearly 900 colored and half-tone illustrations. Prices: Cloth, ^7.00; Sheep or Half-Morocco, $8.00. The advent of each successive volume of the series of the American Text- Books has been signalized by the most flattering comment from both the Press and the Profession. The high consideration received by these text-books, and their attainment to an authoritative position in current medical literature, have been matters of deep international interest, which finds its fullest expression in the demand for these publications from all parts of the civilized world. In the preparation of the "American Text-Book of Obstetrics" the editor has called to his aid proficient collaborators whose professional prominence entitles them to recognition, and whose disquisitions exemplify Practical Obstetrics. While these wTiters were each assigned special themes for dis- cussion, the correlation of the subject-matter is, nevertheless, such as ensures logical connection in treatment, the deductions of which thoroughly represent the latest advances in the science, and which elucidate the best modern methods of procedure. The more conspicuous feature of the treatise is its wealth of illustrative matter. The production of the illustrations had been in progress for several years, under the personal supervision of Robert L. Dickinson, M. D., to whose artistic judgment and professional experience is due the most sumptuously illustrated work of the period. By means of the photographic art, combined with the skill of the artist and draughtsman, conventional illustration is super- seded by rational methods of delineation. Furthermore, the volume is a revelation as to the possibilities that may be reached in mechanical execution, through the unsparing hand of its publisher. COXTRIBUTORS : Dr. James C. Cameron.

"At first glance we are overwhelmed by the magnitude of this work in several respects, viz. : First, by the size of the volume, then by the array of eminent teachers in this depart- ment who have taken part in its production, then by the profuseness and character of the illustrations, and last, but not least, the conciseness and clearness with which the text is ren- dered. This is an entirely new composition, embodying the highest knowledge of the art as it stands to-day by authors who occupy the front rank in their specialty, and there are many of tiiem. We cannot turn over these pages without being struck by the superb illustrations which adorn so many of them. We are confident that this most practical work will find instant appreciation by practitioners as well as students." — Nei.u York Medical Times. Permit me to say that your American Text-Book of Obstetrics is the most magnificent medical work that I have ever seen. I congratulate you and thank you for this superb work which alone is sufficient to place you first in the ranks of medical publishers. With profound respect I am sincerely yours, Alex. J. C. SKE>fE.

AN AMERICAN TEXT-BOOK OF SURGERY. Edited by Wil- liam \V. Klen, M.D., LL.D., and J. William White, M. D., Ph. D. Forming one handsome royal-octavo volume of 1250 pages (10x7 inches), with 500 wood-cuts in text, and 37 colored and half-tone plates, many of them engraved from original photographs and drawings furnished by the authors. Prices : Cloth', $7.00 net; Sheep or Half- Morocco, ^8.00 net. SECOND EDITION, REVISED AND ENLARGED, With a Section devoted to "The Use of the Rbntgen Rays in Surgery." The want of a text-book which could be used by the practitioner and at the same time be recommended to the medical student has been deeply felt, espe- cially by teachers of surgery; hence, when it was suggested to a number of these that it would be well to unite in preparing a text-book of this description, great unanimity of opinion was found to exist, and the gentlemen below named gladly consented to join in its production. While there is no distinctive Amer- ican Surgery, yet America has contributed very largely to the progress of modern surgery, and among the foremost of those who have aided in developing this art and science will be found the authors of the present volume. All of them are teachers of surgery in leading medical schools and hospitals in the United States and Canada. Especial prominence has been given to Surgical Bacteriology, a feature which is believed to be unique in a surgical text-book in the English language. Asep- sis and Antisepsis have received particular attention. The text is brought well up to date in such important branches as cerebral, spinal, intestinal, and pelvic surgery, the most important and newest operations in these departments being described and illustrated. The text of the entire book has been submitted to all the authors for their mutual criticism and revision — an idea in book-making that is entirely new and original. The book as a whole, therefore, expresses on all the important sur- gical topics of the day the consensus of opinion of the eminent surgeons who have joined in its preparation. One of the most attractive features of the book is its illustrations. Very many of them are orip:inal and faithful reproductions of photographs taken directly from patients or from specimens.

Forming a handsome royal-octavo volume, with 341 illustrations in text and 38 colored and half-tone plates. Prices : Cloth, 36.00 net; Sheep or Half-Morocco, $7.00 net. SECOND EDITION, THOROUGHLY REVISED. In this volume all anatomical descriptions, excepting those essential to a clear understanding of the text, have been omitted, the illustrations being largely de- pended upon to elucidate the anatomy of the parts. This work, which is thoroughly practical in its teachings, is intended, as its title implies, to be a working text-book for physicians and students. A clear line of treatment has been laid down in every case, and although no attempt has been made to dis- cuss mooted points, still the most important of these have been noted and ex- plained. The operations recommended are fully illustrated, so that the reader, having a picture of the procedure described in the text under his eye, cannot fail to grasp the idea. All extraneous matter and discussions have been carefully excluded, the attempt being made to allow no unnecessary details to cumber the text. The subject-matter is brought up to date at every point, and the work is as nearly as possible the combined opinions of the ten specialists who figure as the authors. COXTRIB1JTORS : Dr. Henry T.

Books specially devoted to this subject are few, and in our te.xt-books and systems of surgen.- this part of surgical pathology is usually condensed to a de- gree incompatible with its scientific and clinical importance. The author spent many years in collecting the material for this work, and has taken great pains to present it in a manner that should prove useful as a text-book for the student, a work of reference for the busy practitioner, and a reliable, safe guide for the surgeon. The more difficult operations are fully described and illustrated. More than one hundred of the illustrations are original, while the remainder were selected from books and medical journals not readily accessible. "The most exhaustive of any recent book in English on this subject. It is well illus- trated, and will doubtless remain as the principal monograph on the subject in our language for some years.

This valuable work is now published in German, English, Russian, and Italian. The issue of a third American edition within two years indicates the favor with which it has been received by the profession. THE PICTORIAL ATLAS OF SKIN DISEASES AND SYPHI- LITIC AFFECTIONS.

By Emily A, M, Stoney, Graduate of the Training-School for Nurses, Lawrence, Mass.; Superintendent of the Training-School for Nurses, Carney Hospital, South Boston, Mass. 456 pages, handsomely illustrated with 73 engravings in the text, and 9 colored and half-tone plates. Cloth. Price, ^^1.75 net. SECOND EDITION, THOROUGHLY REVISED. In this volume the author explains, in popular language and in the shortest possible form, the entire range of private nursing as distinguished from hospital nursing, and the nurse is instructed how best to meet the various emergencies of medical and surgical cases when distant from medical or surgical aid or when thrown on her own resources. An especially valuable feature of the work will be found in the directions to the nurse how to improvise everything ordinarily needed in the sick-room, where the embarrassment of the nurse, owing to the want of proper appliances, is fire- quently extreme. The work has been logically divided into the following sections : I. The Nurse : her responsibilities, qualifications, equipment, etc. II. The Sick-Room: its selection, preparation, and management. III. The Patient : duties of the nurse in medical, surgical, obstetric, and gyne- cologic cases. IV, Nursing in Accidents and Emergencies. V. Nursing in Special Medical Cases. VI. Nursing of the New-born and Sick Children, VII. Physiology and Descriptive Anatomy. The Appendix contains much information in compact form that will be found of great value to the nurse, including Rules for Feeding the Sick ; Recipes for Invalid Foods and Beverages ; Tables of Weights and Measures ; Table for Computing the Date of Later; List of Abbreviations ; Dose-List; and a full and complete Glossary of Medical Terms and Nursing Treatment. "This is a well-written, eminently practical volume, which covers the entire range of private nursing as distinguished from hospital nursing, and instructs the nurse how best to meet the various emergencies which may arise and how to prepare ever^-thing ordinarily needed in the illness of her patient." — American Journal of Obstetrics and Diseases of ll'owen and Children, Aug., 1896.

The purpose of the writer in this work has been to furnish the student of His- tol<^, in one volume, with both the descriptive and the practical part of the science. The first two chapters are devoted to the consideration of the gereral methods of Histolc^' ; subsequent!}-, in each chapter, the structure of the tissue or organ is first systemaiically described, the student is then taken tutorially over the specimens illustrating it, and, finally, an appendix affords a short note of the m^hods of jH-ej3aration.

Chemists are so multiplying compounds, that, if each compound is to be thor- oughly studied, investigations must be carried far enough to determine the prac- tical importance of the new agents. " Especially valuable because of its completeness, its accuracy, its systematic consider- ation of the properties and therapy of many remedies of which doctors generally know but little, expressed in a brief yet terse manner." — Chicago Clinical Review.

A PRACTICAL work on gynecology for the use of students and practitioners, written in a terse and concise manner. The importance of a thorough know- ledge of the anatomy of the female pelvic organs has been fully recognized by the author, and considerable space has been devoted to the subject. The chap- ters on Operations and on Treatment are thoroughly modern, and are based upon the large hospital and private practice of the author. The text is eluci- dated by a large number of illustrations and colored plates, many of them being original, and forming a complete atlas for studying embryology and the anatomy of ih.^ female genitalia, besides exemplifying, whenever needed, morbid condi- tions, instruments, apparatus, and operations. Second Edition, Tlioroiighly Revised, The first edition of this work rnet with a most appreciative reception by the medical press and profession both in this country and abroad, and was adopted as a text-book or recommended as a book of reference by nearly one hundred colleges in the United States and Canada. The author has availed himself of the opportunity afforded by this revision to embody the latest approved advances in the treatment employed in this important branch of Medicine. He has also more extensively expressed his own opinion on the comparative value of the different methods of treatment employed. "One of the best text-books for students and practitioners which has been published in the English language; it is condensed, clear, and comprehensive. The profound learning and great clinical experience of the distinguished author find expression in this book in a most attractive and instructive form. Young practitioners, to whom experienced consultants may not be available, will find in this book invaluable coimsel and help." Thad. a. Reamy, M.

Based upon the teaching and methods laid down in the larger work, this will not only be useful as a supplementary volume, but to those who do not already possess the text-book it will also have an independent value as an aid to the practitioner in gynecological work, and to the student as a guide in the lecture- room, as the subject is presented in a manner at once systematic, clear, succinct, ?jid practical.

" This work is so far superior to others on the same subject that we take pleasure in call- ing attention briefly to its excellent features. It covers the subject thoroughly, and will prove invaluable both to the student and the practitioner. The author has introduced a number of valuable hints which would only occur to one who was himself an experienced teacher of obstetrics. Ihe subject-matter is clear, forcible, and modern. We are especially pleased with the portion devoted to the practical duties of the accoucheur, care of the child etc. Ihe paragraiphs on antiseptics are admirable; there is no doubtful tone in the direc- tions given.

Saunders^ New Series OF Manuals for Students and Practitioners. THAT there exists a need for thoroughly reliable hand-books on the leading branches of Medicine and Surgery is a fact amply demonstrated by the favor with which the SAUNDERS NEW SERIES OF MANUALS have been received by medical students and practitioners and by the Medical Press. These manuals are not merely condensations from present literature, but are ably written by well-known authors and practitioners, most of them being teachers in representative American colleges. Each volume is concisely and authoritatively written and exhaustive in detail, without being encumbered with the introduction of "cases," which so largely expand the ordinary text- book. These manuals will therefore form an admirable collection of advanced lectures, useful alike to the medical student and the practitioner : to the latter, too busy to search through page after page of elaborate treatises for what he wants to know, they will prove of inestimable value ; to the former they will afford safe guides to the essential points of study. The SAUNDERS NEW SERIES OF MANUALS are conceded to be superior to any similar books now on the market. No other manuals afford so much information in such a concise and available form. A liberal expenditure has enabled the publisher to render the mechanical portion of the work ^vorthy of the high literary standard attained by these books. Any of these Manuals will be mailed on receipt of price (see next page for List). W. B. SAUNDERS, Publisher, 925 Walnut Street, Philadelphia, SAUNDERS' NEW SERIES OF MANUALS. VOLUMES PUBLISHED.

SAUNDERS' QUESTION COMPENDS. Arranged in Question and Answer Form. THE LATEST, MOST COMPLETE, and BEST ILLUSTRATED SEEIES OF- COMPENDS EVEE ISSUED. Now the Standard Authorities in Medical Literature WITH Students and Practitioners in every City of the United States and Canada. THE REASON WHY. They are the advance guard of " Student's Helps " — that do help; they are the leaders in their special line, ivell and authoritatively written by able men, who, as teachers in the large colleges, know exactly what is wanted by a student preparing for his examinations. The judgment exercised in the selection of authors is fully demonstrated by their professional elevation. Chosen from the ranks of Demonstrators, Quiz-masters, and Assistants, most of them have be- come Professors and Lecturers in their respective colleges. Each book is of convenient size (5x7 inches), containing on an average 250 pages, profusely illustrated, and elegantly printed in clear, readable type, on fine paper. The entire series, numbering twenty-four subjects, has been kept thoroughly revised and enlarged when necessary, many of them being in their fourth and fifth editions. TO SUM UP. Although there are numerous other Quizzes, Manuals, Aids, etc. in the mar- ket, none of them approach the " Blue Series of Question Compends;" and the claim is made for the following points of excellence : 1.

Several years of exhaustive research have been spent by the authors in the great medical libraries of the United States and Europe in collecting the material for this work, fledical literature of all ages and all languages has been carefully searched, as a glance at the Bibliographic Index will show. The facts, which wnll be of extreme value to the author and lecturer, have been arranged and annotated, and full rei'erence footnotes given, indicating whence they have been obtained. In \iew of the persistent and dominant interest in the anomalous and curious, a thorough and systematic collection of this kind (the first of which the authors have knowledge) must have its own peculiar sphere of usefulness. As a complete and authoritative Book of Reference it will be of value. not only to members of the medical profession, but to all persons interested in general scientific, sociologic, and medico-legal topics ; in fact, the general inter- est of the subject and the dearth of any complete work upon it make this volume one of the most important literary innovations of the day. An especially valuable feature of the book consists of the Indexing. Besides a complete and comprehensive General Index, containing numerous cross-references to the subjects discussed, and the names of the authors of the more important repDrts. there is a convenient Bibliographic Index and a Table of Contents. The plan has been adopted of printing the topical heading^S in bold^^ face type, the reader being thereby enabled to tell at a glance the subject- matter of any particular paragraph or page. Illustrations have been freely employed throughout the work, there being 165 relief cuts and 130 half-tones in the text, and 12 colored and half-tone full- page plates — a total of over 320 separate figures. The careful rendering of the text and references, the wealth of illustrations, the mechanical skill represented in the tN-pography, the printing, and the bind- mg, combine to make this book one of the most attractive medical publications ever issued.

GOULD, A. M., M. D. Assisted by Eminent American Specialibts and Teachers. ?i Notwithstanding the rajrid multiplication of medical and sui^cal works, still these publications fail to meet fiilly the requirements of the general physician^ inasmuch as he feels the need of something more than mere text -books of well- known [Hinciples of medical science. Mr. Saunders has long been impressed with this fact, which is confirmed by the unanimity of expression from the pro- fession at large, as indicated by ad\ices from his large corps of canvassers. This deficiency would best be met by current journalistic literature, but most practitioners have scant access to this almost unlimited source of information, and the busy practiser has but Uttle time to search out in periodicals the many interesting cases whose study would doubtless be of inestimable value in his practice. Therefore, a work which places before the physician in convenient form CM epitomisation of this literature by persons competent to pronounce upon The Value of a Discovery or of a Method of Treatment cannot but conmiand his highest appreciation. It is this critical and judicial $ function that will be assumed by the Editorial staff of the " American Year- Bc«ok of Medicine and Suigery." a' It is the special purpose of the Ekiitor, whose experience pecuharly qualifies » hira for the jx^eparation of this work, not only to review the contributions to ^ American journals, but also the methods and discoveries reported in the leading ^ medical journals of Europe, thus enlarging the survey and making the work "^ characteristicallv international. These reviews will not simply be a series of -:" digested abstracts indiscriminately run together, nor will they be retrospective * :: *' news" oiu or two years old, but the treatment presented will be synthetic ^ and dogmatic^ and will include only what is new. Moreover, through expert * condensation 1^ experienced writers these discussions will be Comprised in a Single Volume of about 1200 Pages. The work will be replete with original and selected illustrations skilfully reproduced, for the most part in Mr. Saunders" own studios established for the purpose, thus ensuring accuracy in delineation, affording efficient aids to a right comprehension of the text, and adding to the attractiveness of the volume.
