Part 57

In the operation for femoral hernia, the position and preliminaries are the same as for inguinal. A longitudinal incision is made from above the margin of Poupart’s ligament to a little below the middle and most prominent part of the tumour. This is crossed by another at its lower extremity, the whole resembling in figure the letter T inverted; and the two flaps so marked out, are reflected. Sometimes a single incision, from above the neck of the tumour to the lower border of it, is sufficient to afford room for the after proceedings. For some years past I have performed an incision along the course of the ligament of Poupart, with another falling from it over the body of the tumour like the letter T, with the transverse part a little awry. In cases of very large femoral hernia, such as that seen on the next page, the incisions, as in the large inguinal tumour, must be made over the situation of the femoral ring, and to a limited extent. In this case the symptoms had existed for eight days, and had been latterly very urgent, there being profuse feculent vomiting, and great depression of the powers of life. There was a large mass of bowel protruded: this was all returned, and the patient, though well advanced in life, made a rapid recovery. A cast was obtained after her death, which happened several years afterwards. It is seldom indeed that femoral hernia attains such a size. I have seen it in the male, however, nearly one half the size of the swelling here shown. The tumour is often not larger than a walnut, seldom exceeding the size of a small apple. One layer is found covering the sac, furnished by the strong and dense cellular tissue which occupies the space under the crural arch and falciform process of the fascia lata: it is generally denominated the fascia propria, and has been described improperly, it would appear, as the sheath of the femoral bloodvessels; at the lower part of the tumour it is generally wanting. It is carefully divided, so as to expose the sac. This not unfrequently is thickened very considerably, a quantity of dense fatty matter being intimately incorporated with it; but in general it is thin, and appears of a dark colour, in consequence of the bowel and effused bloody serum being seen through it. It is opened with great caution, part of it being raised and touched with the edge of the knife held horizontally, or nearly so. The aperture, thus formed, is enlarged by means of the probe-pointed knife, which is carried upwards along the forefinger of the left hand. Some recommend that the sac should be left undivided, and that the stricture should be relieved by passing the knife on the outside; others, that only the neck of the sac should remain entire, and the stricture be attacked also on the outside of the peritoneum. But this appears an unnecessary and unprofitable precaution. The extreme difficulty of returning the sac is now well known and generally acknowledged; indeed, reduction of it, whether opened or not, is practicable only in recent cases. Its neck, besides, is firmly constricted; and the bowel may and will remain strangulated when returned along with its sac, for the peritoneum long retains the contraction at its strictured point. The stricture cannot be well relieved unless the neck of the sac is cut along with the resisting fibres exterior to it. After the sac has been opened, the forefinger of the left hand is passed up to the crural ring; and it should be recollected that this opening is very small, even in most cases in which a hernia of ordinary size has existed for some time. It is capable of great dilatation, gradual however, so that, in very old and large ruptures, it may admit two or three fingers easily. But in general only the nail of the finger can be insinuated into it; and this is a better and safer conductor for the knife than a grooved director. The edge of the stricture is felt very sharp; the point of the finger is turned towards the pubes, and along it a narrow, blunt-pointed, curved bistoury is passed in close contact, and with the edge towards the pubes; its mere point is pushed beyond, and then the position of the blade is changed: its back is turned upon the finger. This slight motion is of itself often sufficient to relieve the constriction on the protruded parts, and permit their reduction; if not, a few more fibres are cut by raising the handle of the knife gently from the palm of the hand. The direction of this incision is towards the tuberosity of the pubes, inwards and forwards. Thus only the crescentic portion of the crural arch is cut; and the division of this produces sufficient relaxation of the neighbouring parts. There is danger in cutting directly forwards, particularly in the male, at least if the incision be made to any considerable extent; there is a risk of wounding the spermatic chord, and the obturator artery has also been met with in a few instances coursing round the neck of the sac. This distribution of the artery, however, is rare, and can occur only when the epigastric and obturator arise by a long common trunk, and even then it may not encircle the neck of a hernia, as I have witnessed. Occasionally a vessel of considerable size passes round the opening, connecting the epigastric with the obturator, when these arteries follow their usual course; and this also may surround the neck of the sac. If vessels should exist in this situation in a person the subject of operation, as has not happened so far as I know, they would be felt by the finger used to conduct the knife. And the bistoury should never be passed—for there is no necessity for it—through the opening so far as to meet with a vessel, even if awkwardly placed. The danger of cutting forward and to any extent has already been spoken of; such incision can answer no good purpose. The stricture is not in Poupart’s ligament—though at one time it was proposed to cut this through without interfering with the tumour at all—but in the crural arch underneath, and in a manner independent of the strong tendinous chord and expansion. The crural arch is formed by the junction of the fasciæ of the thigh and abdomen, superficial and deep. It is inserted into the linea ileo-pectinea, where the tendon of the external oblique has no connection, and is strengthened by fibres from the internal oblique, transverse, and recti muscles. The crural aperture formed by this arch is relaxed by flexion and inversion of the thigh, and by relaxation of the abdominal parietes. And this fact requires to be attended to, after operation as well as during the taxis, so as to facilitate replacement of the protruded parts.

The same attention to the state of the parts in judging of the propriety or not of reduction after operation, and the same after treatment, both general and local, is requisite in crural hernia as in inguinal. When the parts are reduced, the edges of the wound are brought together by means of a few stitches; a graduated compress, of proper dimensions, is applied, and retained by a spica bandage. If this is neglected, there is a risk of the parts again descending. Afterwards large mild enemata are to be administered, and, after some hours, purgatives, so as to procure copious and free evacuation of the bowels. In many cases after reduction, the bowels cannot by any means be got to act downwards. This seems sometimes to arise from a sort of paralytic state of the fibres of the part which has been extruded and compressed. Again, it often arises from an indentation of the coats of the bowel at the point where they have been tightly embraced and compressed by the sharp edge of the opening, as here represented. The engorged and dark state of the upper portion of bowel contrasts well with the lower, which is generally empty, contracted, and pale. If the stomach continue unsettled, a sinapism may be applied to the epigastrium, or solid opium exhibited. Subsequently it may be necessary to bleed locally, or generally, or both; in other cases the strength from the first requires support. After cicatrisation, a well adapted truss must be constantly worn.

Umbilical hernia is generally congenital. The tendinous parietes are often deficient to a great extent, and there is consequently much fulness along the umbilical chord. The plan of embracing such tumours in children by ligature, as at one time extensively practised, is now abandoned, there being much risk of peritoneal inflammation and fatal issue. The surgeon is now content with reducing the hernia, and applying a truss, to prevent displacement, as in other forms of protrusion; and if this be done in early life, and the apparatus carefully worn, the opening contracts, and the patient may ultimately be cured. The tumour may become strangulated, though rarely in the adult; it is generally large, and almost solely occurs in females. The sac has no covering but the skin and cellular tissue and fatty matter. A small incision is made through the sac and its investments, either on one side of the tumour, or in the mesial line at its lower aspect. The stricture is then divided with care, the parts reduced, the wound approximated, and a compress applied. Opening the tumour throughout its whole extent is hazardous and unnecessary. The same remarks apply to the proceedings in cases of ventral hernia. In corpulent females the tumour is sometimes scarcely prominent, and is only discovered as a flattened cake through the fatty matter.

The contents of hernia are often in a very bad state, either dark-coloured throughout, or studded with dark tender spots. Lymph is often effused all over the parts, gluing them to one another, and to the sac. This effusion, which generally takes place to the greatest extent at the neck of the sac, is a wise provision made by nature against the accidents of the disease; inasmuch as a barrier is thereby formed between the cavity of the abdomen and the extruded parts, preventing, in a great measure, the destruction of the latter from affecting the abdominal viscera. For example, a portion of protruded intestine sloughs, the feculent matter is effused, and, had not this adhesion to the neck existed, the gut might have slipped back into the abdomen, its contents would have escaped there, and a fatal result would have been the inevitable consequence. Still, notwithstanding the salutary effusion, the bowel may ulcerate at its upper part, and, giving way within the belly, produce rapid death. The bowel, where embraced by the stricture, is contracted and thickened, and dilated above. At the lower part of this dilatation the coats are apt to give way by ulceration, even after incision of the constricting parts and reduction. The contraction does not disappear quickly. In some cases it continues to such an extent as to keep up obstructions to the fecal matter, and cause a fatal issue from this cause alone, as noticed above.

Often, on opening the sac, in long neglected cases, a discharge takes place of fetid air and thin feculent matter, the bowel has mortified either entirely or in patches; in the latter case, presenting the appearance of having been perforated at various points. Few constitutions can bear up under such mischief. In some, if an opening be not made, the integuments slough, and the patient, rallying after discharge from the bowel takes place, recovers after losing a portion of integument, of intestine, and perhaps of omentum. In others, and they constitute the majority, the system sinks, before discharge from the bowel is effected, by sloughing of the external parts.

The surgeon is called on to operate in the worst possible circumstances, provided the patient is not in articulo mortis. Even after many days of feculent vomiting the bowels may be found tolerably healthy. The sac must be opened carefully, and the stricture is to be relieved without disturbing the adhesions that have formed. The bowel, when dead, or evidently gangrenous, is to be opened, and the discharge of feces by the wound promoted. If returned into the abdomen, the sloughs will separate, in all probability, and feculent effusion take place, causing death in a very few hours. Sometimes the patient lingers longer than could be expected, and I have known a female survive upwards of a hundred hours after the occurrence of effusion into the abdomen, from the giving way of an ulcer in the stomach. The dressing should be light, and the patient’s strength must be supported in every way, by the mouth, and by the anus when the injured part is high in the canal. The separation of the sloughs is to be encouraged. The extent of sloughing need not dishearten the surgeon, for large portions of bowel, several feet in length, have mortified, and the patients recovered, with artificial anus, either temporary or for life.

In artificial anus, when this has followed upon destruction of the bowel to a considerable extent, the intestine has contracted firm adhesion to the hernial sac at the opening in the abdominal parietes; through the opening in the bowel exterior to this the feculent matter is discharged externally, and by the adhesion is prevented from being effused into the abdominal cavity. The protruded bowel in which the sphacelation has occurred may be said to be thereby divided into an upper and an under portion,—one, the upper, discharging, the other, collapsed and empty; these lie parallel to each other, in close contact, and usually adhering, from the abdominal or crural ring downwards, to each other, and to the hernial sac. The hernial sac seldom sloughs entirely; in almost every case its neck remains sound; to this remaining part the intestine adheres. The deficiency in the integuments and cellular tissue, through which the feculent matter escapes, gradually contracts, and the aperture in that portion of the hernial sac which is exterior to the intestine also diminishes; but at the same time dilatation takes place in the immediate vicinity of the intestinal orifices, so that a funnel-like cavity is formed for the evacuation of feces, extending from the opening in the bowel to the opening in the skin—its narrowest part being at the latter situation, its most capacious surrounding the intestine. The cellular tissue intermediate between the integument and hernial sac becomes condensed, and forms a membranous lining. By this cavity an imperfect communication is established between the two portions of bowel, part of the feculent matter returning through the lower intestinal orifice, and part escaping externally. But this communication must be indeed very imperfect at first, since the two portions of bowel lie parallel to each other, and their coalescing sides form an acute angular projection into this funnel-shaped cavity. The lower portion is necessarily much diminished in calibre, being in a great measure unaccustomed to the usual distension, and its collapsed orifice is retracted a little higher than that of the superior. On account of these circumstances feculent matter cannot pass straight onwards from one portion of bowel to the other, but must first traverse the funnel-shaped cavity; and even then it is but a small quantity that reaches the rectum. Indeed, in most cases of artificial anus, nothing but occasional flatus passes by the original outlet for weeks or months. After some time the bowel retracts, but cannot leave the adhesion in the groin: by this retraction the orifices may be brought in a more direct line with each other, and the natural passage of the feces be somewhat assisted.

When one or more slight patches of discoloration are observed after division of the sac, it may be returned, it being most probable that the parts will recover after removal of the stricture. When any portion has given way, of course no one can contemplate reduction; and when the whole calibre has sloughed it is absurd to attempt separation of the adhesions which must exist, dividing the external from the internal parts.

In mortification of a protruded knuckle, or part only of the calibre of bowel, the symptoms are at first severe. These are vomiting, pain, and symptoms of enteritis; perhaps the bowels are obstructed for some time, but evacuation again takes place, as happened in the following remarkable and instructive case. A gentleman, nearly eighty years of age, was, during the action of medicine, suddenly seized with pain in the groin. A very small tumour was observed— he became sick—and when I visited him for the first time two days after, he had no further evacuations from the bowels, he vomited constantly bilious fetid matter, and he began to complain of pain in the abdomen. Pressure was kept upon the tumour, which protruded at the crural aperture, for some time, with the effect of diminishing its size very considerably. On returning in a couple of hours with Sir B. Brodie, with the intention of cutting down upon the swelling, the bowels had been freely relieved, the vomiting had entirely ceased, and there was not the slightest vestige of tumour to be perceived or felt, on the most attentive examination. The patient had a good night, but in the morning had a recurrence of the symptoms: these continued, and a fatal termination shortly occurred; still no tumour could be detected before or after death. It was supposed that the obstruction might have been caused by a continuance of the constriction of the bowel, where it had been nipped by the stricture. On a post-mortem examination, there was found an exceedingly small portion of the coat of the bowel still entangled in the crural ring, whilst a larger portion, which bore marks of having been protruded, was thus entangled, and confined to the spot. The bowel, though not completely obstructed, was narrowed by the confinement of part of its parietes.

Abscess often occurs externally to a small swelling of this nature, and on the giving way of the integument, matter, flatus, and thin feces are discharged. A _fecal fistula_ remains for some time; but, by the aid of lymph and granulations, the breach in the parietes of the bowel is repaired gradually, the feces resume their natural course, and the external opening heals.

When the whole calibre has sloughed, and even when a large extent of bowel has come away, and there is still a chance of the patient recovering from the artificial anus by natural means, after the lapse of many months. As already remarked, the intestinal orifices retract, and come more into a straight line. A mucous discharge occurs from the lower bowels along with the passage of flatus, and at last part of the feces is voided by the rectum. The discharge from the external opening diminishes, and ultimately ceases, perhaps only a minute fistula remaining, through which a few drops of fluid, sometimes feculent, sometimes limpid, may occasionally escape. The funnel-shaped cavity previously contracts into a narrow fistula. This desirable result may be assisted and hastened by gentle pressure; and, after the feculent discharge has nearly ceased from the fistulous opening, the healing of this may be accelerated by the cautery lightly applied. It has been proposed to destroy the projecting septum between the two portions of bowel, either by ligature or by the pressure of forceps; but this should not be attempted unless nature seems unable to effect a cure. The former method consists in including a considerable part of the septum in ligature, so as to induce condensation of the parts by effusion of lymph, and destruction of the projecting portion. This has not been found very successful. The application of forceps presents a more rational expectation of cure. The external opening is dilated, and the situation of the septum ascertained. One blade of metallic forceps, with blunt serrated edges,—Dupuytren’s,—is passed into the one intestinal orifice, and the other into the opposite; the handles of the instrument are then approximated, locked, and fastened with a screw, and by means of the last-mentioned part of the apparatus the degree of pressure is regulated. Pain of the abdomen, furred tongue, loss of appetite, sickness, vomiting, and constitutional irritation, generally follow this proceeding, but gradually subside on the employment of enemata and fomentations, and on lessening the pressure of the forceps. The septum cannot long withstand the continued compression, and by its destruction the chance of cure is greatly augmented. The proceeding is, besides, not so dangerous as might at first be supposed; for effusion of lymph takes place to a considerable extent above the part grasped by the forceps, gluing the portions of bowel firmly to each other, and forming a new barrier against any of the feculent matter escaping inwardly. Attempts may be made to repair the loss of substance in the skin by paring the edges of the opening, and affixing a flap taken from the neighbourhood.[45]

There is a greater chance of recovery from the inconvenience of artificial anus after hernia than after wounds. If the opening in the bowel be near the stomach, the patient will die from inanition. When it is lower in the intestinal tube, nutrition is more perfect, and the patient can be further supported by nutritive enemata. When no natural cure is likely to take place, the inconvenience will be palliated by a truss with a soil pad being worn, so as to retain the feces till a favourable opportunity occurs for evacuation; or a soft plug of lint may be inserted into the aperture, and retained by a compress and roller. Prolapsus of the mucous membrane of the gut sometimes takes place through the artificial anus, and is reduced with difficulty. The use of a truss or tent, already mentioned, will tend to prevent the occurrence. Great attention to cleanliness is required when the opening cannot be closed.

Operations for other kinds of hernia, if discovered during life, are to be conducted on similar principles with those for inguinal and crural. The surgeon must be guided by his anatomical knowledge. No positive rules can be given.

In _Ascites_, or accumulation of fluid in the peritoneal cavity, the surgeon is not unfrequently called upon to relieve the patient, when the abdominal parietes are much distended, and the functions of the viscera of the abdomen and thorax interrupted. He must, however, exercise his own judgment in regard to the case, and convince himself of the propriety of operating. He must examine into the symptoms, and ascertain that the tumour is really caused by accumulation of fluid in the bag of the peritoneum. In ascites, the abdomen has swelled slowly and uniformly, and distinct fluctuation is felt when the hand is placed on one side of the swelling, and gentle tapping made at the other. There is considerable difficulty of breathing, uneasiness in the abdomen, usually increased by pressure, thirst, and scanty secretion of urine. It ought to be remembered that other affections have been confounded with ascites, and lamentable operative mistakes committed in consequence. Trocars have been thrust into the belly for tympanitis, either of the bowels or of the peritoneum—for solid tumours of the viscera—for enlargement of the ovaria.
