Part 56

Returning the contents of the hernia into the abdomen is the only effectual means of counteracting the direful effects of strangulation; and the propriety of an early recourse to this measure must be quite apparent. It is indispensable, and no delay is warrantable. The means for accomplishing it must be varied, according to the state of the parts, the duration of strangulation, and the general symptoms. The most simple method, and that which should first be attempted in ordinary cases, is the _taxis_; that is, reduction by pressure with the hand. In this, the position of the patient is of importance; it should be such as effects relaxation of the tendinous structures through which the hernia has protruded, and through which it is to be returned. With this view he is placed on his back, with the shoulders and pelvis elevated, and in crural hernia the thigh is bent on the trunk, and turned towards the opposite side; thus the aperture is relaxed along with the fasciæ which compose it. Long ago, the positions into which the patients were forced for the cure of hernia were various, and generally awkward; they all tended towards more or less complete inversion of the erect posture, and thus it was supposed that the abdominal bowels dragged on those protruded, and thereby assisted reduction. But the viscera are equally pressed on in every position of the body; it is not they, but the external parts, that are affected by change of posture. During the attempts at reduction, the patient should be exhorted not to strain or resist, but to relax his muscles; and it will be well to engage him in conversation, that he may not have an opportunity of keeping his lungs distended, and thereby acting forcibly on the abdomen. At first the pressure should be general, applied either with one hand or with both, according to the size of the tumour, so as to diminish the contents. If air be heard gurgling at the neck of the swelling, the chance of success may be considered good, for a return of part of the bowel’s contents is thereby indicated. Then a gentle kneading should be made at the neck with the fingers of one hand, while with the other general pressure is kept up. The impression made is at first slight and gradual; but, when a portion of the bowel returns, the rest of it slips up suddenly. The return of omentum is always slow, and the last part requires as much manipulation as the first. The direction of the pressure must be varied according to the case. In inguinal and ventro-inguinal hernia, it is made in the direction of the neck of the sac; in the former upwards and outwards, in the latter upwards and backwards; and previously the body of the tumour should be brought into the same line with its neck. In crural hernia the pressure must first be made towards the centre of the thigh, so as to bring the whole tumour into the same direction with its neck, and then upwards. In umbilical, the pressure is straight backwards. Small herniæ, and those of recent origin, are with difficulty reduced; their neck is narrow, and the passage proportionately small; the crural are usually of this description. In all herniæ, after strangulation has existed for some time, and adhesions formed, particularly at the neck, reduction is almost impossible.

The taxis is to be neither attempted nor persevered in after the hernia has become tender and inflamed. No good can be done by it, and the patient’s chance of recovery by operation is much diminished. Even when no pain is felt in such circumstances, any degree of force must be prejudicial. Mortification of the bowels is often hastened in consequence of the taxis being unskilfully employed by ill-informed persons, who are often determined, at all risks, and at all stages of the affection, to accomplish speedy reduction of the viscera. The surgeon will take care to inform himself of all particulars—as to the duration of strangulation, the previous state of the tumour, if it was all, or only in part reducible, as to its size, &c.—before proceeding in any way. Great mischief is likely to accrue from the tumour being handled, perhaps roughly, by many people. If the taxis is gone about, however, in proper time, and in the right way, it ought almost always to prove successful. It is very desirable indeed that this should be the case, seeing that all the bad symptoms in ninety-nine out of a hundred cases instantly subside; whereas, after the reduction by incision, there is always great risk from the opening of the peritoneal sac alone.

Certain means may assist the taxis, but they should not be long continued or often repeated. Venesection can be employed only in strong plethoric patients, in the very first stage of strangulation, and before the patient is exhausted by the distressing symptoms. It is had recourse to in order to induce syncope, or an approach to it; during which general relaxation takes place, and reduction may be attempted with advantage. With that view the patient is placed erect, and a large orifice made in the vein of one or both arms, so that a moderate quantity of blood suddenly abstracted may have a powerful effect on the system. In several cases I have found this practice beneficial, but am inclined to say that, in general, it will not be followed with success. In a favourable case, one attempt of this kind may be made, but not repeated. In many states of the constitution, and in the latter stages of the disease, bad consequences must follow the practice. But in regard to it or any other remedy, it would be folly to lay down positive general rules; what may prove useful in one or two instances may answer very badly in the majority of cases that come under treatment. Local bloodletting can have no effect in diminishing the size of strangulated parts; though in inflammation of the contents of the tumour, without strangulation, no more powerful means can be employed.

Purgatives have been recommended with the view of extricating the bowel by increased peristaltic motion; but the symptoms will, to a certainty, be aggravated by their use. Purgative enemata can do little good: if in small quantity, they empty only the rectum; if large, they may reach the strangulated part, but will scarcely have the effect of extricating it.

Emetics, in full or nauseating doses, have been supposed to be indicated in this affection as well as in ileus; but there is in general enough of sickness and vomiting without them, and it is often difficult enough to allay the vomiting even after removal of the obstruction.

The warm bath is greatly trusted in by some, and in many cases it proves a valuable and useful auxiliary to the taxis. It acts beneficially by inducing general relaxation, or even syncope; during which, whilst all resistance of the compressing powers upon the contents is suspended, pressure on the tumour can be employed to good advantage. By steady perseverance, whilst the patient is in the bath, a great majority of strangulated herniæ may be reduced. But neither the general nor the local application of heat, or any other known means, save the edge of the knife, can relax tendinous apertures farther than can be effected by attention to position. Irrecoverable and most precious time may be wasted in preparing the bath; and for this reason such means should never be resorted to, unless they can be commanded at the shortest notice.

Fomentation can do no good. The apertures can be neither relaxed by heat, nor contracted by astringent applications. By the local application of heat, the size of the parts composing the hernia will be augmented, the flatus being rarified, and the effusion and engorgement encouraged.

The cold bath, and the dashing of cold water on the surface, near the seat of the disease, have been tried in some rare cases with most marked success; but this is a practice not generally to be relied on. It can act only by producing sudden and powerful contraction of the coverings, and uniform pressure thereby on the contents. It is, perhaps, only applicable to scrotal hernia. Cold has been applied to the tumour, and even ice, so as to produce frost-bite, but little faith can be placed in such; the practice becomes dangerous after inflammation has existed for some time, the application diminishing the weakened powers of the parts, and accelerating gangrene.

Opium has been given by the mouth, and tobacco by the lower extremity of the alimentary canal; the former may sometimes prove advantageous, but the latter had better be dispensed with. The tobacco is thrown up either as an enema, or in the form of vapour; but the former method is generally preferred. A drachm of the leaves is infused in a pound of water for ten minutes, and one-half of the liquid injected; if this prove insufficient to prostrate the patient, the rest is administered after the lapse of a short interval. But many people have thus been poisoned, and the indiscriminate employment of the supposed remedy cannot be too strongly reprobated; its effects are most severe and unmanageable; the state of collapse is most complete and alarming, and it is often difficult, if not impossible, to bring the patient out of it—to procure reaction. In some cases reduction may be accomplished during the state of extreme debility which follows its use, but I have often seen it fail, and have witnessed the operation afterwards performed on the patients, who were at the time without pulsation, and from whom little blood flowed after the incisions; they never, of course, rallied, and sunk rapidly. Indeed the patient is always in a very unfavourable state for operation after the exhibition of the tobacco enema, though certainly in a very favourable state for reduction being attempted. The strong objection to the medicine I conceive to be its being so extremely unmanageable; it is impossible to say whether the depression of the vital powers that must ensue will be just sufficient to induce that relaxation and debility necessary or favourable to reduction, or whether it will proceed uncontrollable to such a degree as to extinguish life. In general it produces intolerable nausea and depression, universal relaxation of the muscles, coldness of the surface, with clammy exudation, vomiting, violent retching, vertigo, and perhaps insensibility. Were I so unfortunate as to be the subject of strangulated hernia, I should certainly have no tobacco used. After unsuccessful trial of the taxis, I might submit to be bled ad deliquium, and have a surgeon to attempt reduction during syncope; if somewhat more advanced in life, I should prefer the warm bath; if taxis then failed, I should certainly be operated on in a very few minutes afterwards. If the surgeon, after mature consideration, make up his mind as to the course of practice he would wish pursued in his own case, he will be fully alive to the necessity of impressing the utility of it on his patients, and have little difficulty in persuading them to submit to his proposals. No time should be dissipated in administering purges or clysters, or in cold or warm applications.

If the tumour is not very tender, make one good trial of the taxis, not long continued; if a warm bath can be readily commanded, place the patient in it, and employ the taxis when he begins to feel faint. If foiled, and if the patient can bear depletion well, the strangulation being recent, try a full bleeding to syncope; it may save depletion afterwards, and at all events the patient will be none the worse for it. Having failed, as may probably be the case, operate without delay.

The operation, as regards the immediate consequences, is neither formidable nor dangerous of itself; the delaying of it is attended with the most serious and irretrievable mischief. It ought to be performed within a very few hours after the occurrence of strangulation, and, in most instances, without putting off time with the means considered auxiliary to the taxis. Under urgent circumstances, it may be necessary to operate within a quarter of an hour after seeing the patient, as I have often done. In ordinary cases, time must be taken to converse with the patient and his friends, to convince them that all those means likely to assist reduction, and render an operation unnecessary, have been tried. The surgeon must not appear to be in a hurry, though he puts off no time unnecessarily; otherwise his motives may be misconstrued.

The necessity for operating early is greater in small than in large herniæ, in crural than in inguinal. The groin and neighbouring parts are to be shaved, and the patient placed in the recumbent posture, with the shoulders slightly elevated. The mode of operation must be varied according to the nature of the tumour, its size, and other circumstances.

The operation for inguinal herniæ is conducted as follows:—The patient is placed recumbent on a table, or, in private practice, on the side of a bed, his shoulders supported by pillows, and his feet resting upon a stool. An incision is commenced about an inch above the external abdominal ring, and continued to the bottom of the tumour. This latter part of the procedure, however, is applicable only to small and moderately-sized herniæ; in large tumours the wound is not made so low, for in them the bowels may be irreducible, from the quantity protruded, and the contracted state of the abdominal cavity; in such cases the incision should be only to such an extent as is sufficient to enable the operator to reach the stricture. The first cut is carried through the skin and fatty matter, not deeper. The layers are then divided successively, with the hand unsupported; and this is done only at the middle and projecting part of the swelling. It is unnecessary to prolong the incision of the layers along the whole extent of the wound in the integuments, at this stage of the proceedings. In the direct hernia, which is of rare occurrence, there is but one proper layer,—that furnished by the superficial abdominal fascia: not unfrequently there is an imperfect additional envelope, furnished by fibres from the edge of the external ring; sometimes the tumour does not escape through the external ring, and is then of course covered by the tendon of the external oblique; of this I have seen but one instance, and that in a female; but in a common inguinal hernia there are three or four, and these are thickened more or less according to the size and duration of the tumour. The division of these layers must necessarily be conducted with great care and caution. At length the sac is exposed. This is opened by pinching up a portion betwixt the nails of the thumb and forefinger, or with dissecting forceps, and then cutting with the blade of the knife laid horizontally. On wounding the sac, there is usually evacuated a small quantity of brownish serous fluid. The probe-pointed bistoury is then taken up, and insinuated into the opening; and by this instrument, guided on the forefinger of the left hand, the sac and its coverings are divided up to near the ring, and down to near the bottom of the tumour. The hernial contents are thus exposed. These are unravelled, and examined attentively; if only brownish-red, from accumulation of the venous blood, of unbroken surface and unadherent, they are fit to be reduced. The stricture is felt for with the forefinger of the left hand, and into it either the point of the finger or the nail is gently insinuated. The protruded parts, if voluminous, are held down by an assistant; and along the forepart of the finger is passed a probe-pointed, narrow, and slightly curved knife. In carrying this upwards, the blade is placed flat on the finger, and its point, and no more, is passed through the contracted part; its edge is then turned forwards, its back resting on the finger; and by raising the handle gently, a slight incision is made into the more resisting fibres, in the direction of the mesial line. The instrument is withdrawn with the same caution as in its introduction. The finger now enters easily, and by raising it gently and repeatedly the parts are dilated. It is then passed upwards to the site of the internal ring: and if this be found narrow and contracted, the edge of the knife to be directed against it in a similar way, and dilatation to a sufficient extent effected. Now reduction is to be commenced, and in doing so the same precautions are to be observed as in the employment of the taxis. The hernial sac ought in the first place to be fixed by the fingers of the assistant placed in the bottom of it, so that it may be prevented from sliding up along with the contents. A neglect of this rule is often observed to lead to much embarrassment. The parts seem to have passed back into the general cavity; but on withdrawing the pressure they fall down again from the canal, along with the sac which had slipped up so far with them. In general, the omentum, if any, is put back first, and then the bowel; but this must depend on the relative quantity of the parts, and other circumstances. With the right hand the bowel is to be compressed as uniformly as possible; and, if at all obstinate, its reduction may perhaps be accelerated by pulling down a small portion at the neck, so as to facilitate the return of the fecal contents. By gentle pressure with the forefingers one portion is put back after another: it is wrong to attempt sudden and entire reduction; it should be gradual and successive. In many cases, from adhesion, or from the bulk and nature of the hernia, the parts, though sound, cannot or ought not to be reduced; a portion may be got back, but part requires to remain. This can often be ascertained beforehand by properly conducted and previous inquiry into the history of the case, as to the duration of the disease, and the period at which the whole tumour could be made to disappear. In such cases, the stricture should always be freely relieved. When the bowel is mortified, and its contents effused into the sac, care is to be taken not to detach or disturb the adhesions at the neck, and the bowel should be opened so as to allow of free discharge. When the bowel or omentum are comparatively sound, though irreducible, the surgeon must rest contented with relieving the stricture; then cover the parts with the integuments, and promote union of the wound. If it be considered necessary to remove condensed and tuberculated omentum, it is cut off, and separate ligatures of fine thread are applied to every bleeding vessel on the cut surface; the whole mass is not to be included in one noose, as was formerly the practice.
