Foreign bodies may lodge in the rectum—as bones, portions of hard indigestible meat, &c., introduced by the mouth—or clyster-pipes, bougies, &c., which have been passed up per anum. From being the source of constant irritation, and obstructing the functions of the part, they demand removal. Alvine concretions are now rare; they are usually situated in the caput cæcum coli, sometimes in the sigmoid flexure, or in the arch of the colon; they may descend into the rectum, and lodge there.
Children are sometimes born with the anus imperforate, the extremity of the rectum being covered merely by integument, or the bowel terminating an inch or two above the usual site of the anus; or the rectum may be wholly deficient. In the last case, the colon may end in a blind sac at the fundus of the bladder, or it may open either into that viscus or into the vagina.
Treatment of Affections of the Rectum.—In the treatment of hemorrhoids, the cause should be removed if possible; and this may suffice for the cure. When the tumours are recent and small, they may be made to disappear by the use of astringent ointments or decoctions, as of galls, kino, oak-bark, and by sedulous attention to cleanliness of the part. In inflamed tumours, blood may be extracted by leeches or punctures, and hot fomentations afterwards used. Recent hemorrhoids are sometimes got rid of at once by the puncture of a lancet,[50] by which a clot of grumous blood is discharged, with immediate subsidence of the swelling, and abatement of pain. When constriction of the internal tumours or folds of bowel by the sphincter has occurred, the tumour should be replaced if possible. In irritability of the sphincter, a bougie is sometimes used with advantage; and incision of the muscle, by which rest is afforded to the parts, will often effect a cure, after the failure of all other means: this is essential when rugged ulcers or fissures occupy the orifice; the division may be made on either side, certainly not in the mesial line. In most cases, the tumour must be got rid of by the knife or ligature. When the piles are internal, removal by ligature is to be preferred; the patient being made to strain, and thereby bring the tumours as low as possible, a ligature is placed round the base of the swelling, provided its form conveniently admits of it; otherwise the base is pierced by a fixed needle armed with a double ligature, the separate portions of which are applied tightly to the corresponding parts of the base. This operation is very inconsiderately and indiscriminately employed. It can only be warrantable when the tumours are so large as to obstruct the orifice so perfectly as to prevent evacuation, unless they are extruded. Before proceeding to this measure, the bowels should be emptied by mild and repeated purgatives, and afterwards all stimuli should be avoided. It is imprudent to apply ligature to several tumours at once, for serious consequences will most probably ensue, inflammation of the bowel, obstinate constipation, and general excitement.[51] Excision of such piles is contraindicated by the risk of profuse hemorrhage. The bleeding is into the cavity of the bowel, a coagulum is there formed which encourages the flow; and from this cause, and the peculiar situation of the bleeding point, it is with difficulty arrested. When the tumours are external, ligature may certainly be adopted; but here there is no objection to the use of the knife, and excision is much less painful and more speedy. The tumours, along with protruded portions of the mucous lining of the rectum that cannot be reduced, and are changed in structure and function, are readily taken away by the rapid stroke of sharp curved scissors. Or they may be laid hold of and stretched, and their base divided by one or more sweeps of a bistoury. The removal of these tumours, or of a portion of the loose fold of skin or altered mucous membrane which occupies the sphincter in the direction of the bowel, is in general followed by a cure of the prolapsus. The sphincter now acts fully, and on the cicatrisation of the open surface contraction of the tissues occurs to such an extent as to produce a permanent cure without interference with the internal parts. Should hemorrhage follow upon the removal of external tumours or folds, the surgeon has it completely under command. Pressure by a large graduated compress is generally sufficient.
In inflammation of the rectum, the exciting cause often is not discovered; when detected it should be removed without delay. In simple inflammation of the part with violent fever, general bleeding may be required; and in all cases blood should be abstracted locally and freely. Leeches are to be applied to the verge of the anus, and the lower part of the perineum, and hot fomentations afterwards used. Internal antiphlogistics are at the same time not to be neglected. In retention of urine, or great irritability of the bladder, in consequence of the affection of the rectum, the perineum should be leeched and fomented, perhaps, also, the lower part of the abdomen; the use of the catheter should be avoided if possible. When induration takes place in the cellular tissue by the side of the anus, or in the perineum, suppuration must in all probability occur, and poultices, with occasional fomentation, are to be used, though only for a short time; for, as already mentioned, pointing of the matter is not to be waited for in this situation; incision must be had recourse to early, in order to prevent bad consequences. Leeching is sometimes used here, as in purulent formations in other parts, from gross ignorance of the real state of matters; and sometimes their use is continued after fluctuation is distinct, and until the pus begins to ooze through the leech-bites; such is very useless and very dangerous practice; in most cases the internal parts are extensively destroyed before the matter comes spontaneously to the surface.
In the carbunculous state of the cellular tissue, near the rectum, with extensive infiltration, dark integument, and a tendency to sloughing, an early and free opening must be made wherever matter is suspected to have formed, however deeply seated, and in whatever quantity, and whether the parts are indurated or not; nothing but mischief can result from delay. When the cellular substance is destroyed, the incision must be proportionally extensive, to afford a free exit for slough as well as matter. During the suppuration which follows, the system will require good support, and most probably a free administration of stimuli.
It has been recommended that, in abscess extending along the gut, the cavities of the bowel and abscess should be at once laid into one by incision. I have done so, but always found the cure to be tedious. It is better that the matter should first be evacuated through an external opening, that the painful symptoms and constitutional disturbance should be allowed to subside; and that after the cavity has contracted, and the extent of the sinus has been ascertained, the operation should be performed. In the operation the knife is now employed; but in former times the ligature and cautery were in constant use. The old surgeons supposed that there was something malignant in the hardness and callosity attending this disease, and were not contented with opening the cavities, but endeavoured to dissect out the whole parts; and, if foiled in this, they finished the work with a red-hot iron. Indeed the practice of excision was recently in vogue in the Parisian hospitals.
But the operation for fistula has been much simplified. The bowel is generally so much separated from its connexions as to be incapable of again adhering, or of furnishing granulations; and, though capable, healing is effectually prevented by the frequent motion of the parts caused by the action of the sphincter and levator of the anus. One side of the cavity is fixed, whilst the other is in motion. It becomes necessary to lay the cavities of the bowel and of the fistula into one. This can generally be effected with great ease; a salutary degree of excitement follows the use of the knife, rest to the parts is procured, the edges are allowed to retract and adhere to the opposite surface, and the wound heals quickly from the bottom. The surgeon, in his operative procedure on these parts, must use both hands equally well, otherwise he must vary his position, and often put his patient in a very awkward predicament, more particularly if a female. The patient is placed in a stooping posture, with the legs unbent, or kneeling on a chair, and resting his arms on its back, the fundament being turned towards the light. The surgeon inserts the finger, well soaped and oiled, into the rectum, and with the other hand insinuates a curved probe-pointed bistoury into the sinus, using the instrument merely as a probe. Having reached the extreme depth of the canal, the direction of the instrument’s point is changed so as to apply its cutting surface to the coats of the bowel, at that part. The instrument on being thus passed into the bowel is fixed by the finger, and by drawing both outwards, the coats of the bowel and the parts intervening between them and the sinus are divided. All collateral sinuses extending towards the perineum and buttock must be freely divided, for they cannot be expected to contract otherwise. Such is all that is necessary in the generality of cases; but it is evident that the steps of the operation, and the extent and number of incisions, must be varied according to circumstances. A great part of the affected bowel may be pulled down by a director before being cut, as is sometimes done; but the practice is useless and painful. Should hemorrhage take place, it may be restrained by stuffing the wound gently with lint; if this fail, the bleeding vessels are to be secured by ligature; but this is seldom necessary. The bowels should be well cleared out before the operation, so that two or more days may pass over without the parts being required to perform their functions; and, if the bowels are naturally loose, opiates may be administered. Afterwards copious evacuation is to be procured by enemata or gentle laxatives. It is necessary to prevent the external part of the wound from adhering, until the whole has contracted equally, and begun to be filled up by granulations from the bottom; and with this view a piece of lint is interposed between the margins. Stuffing the wound daily with large dossils of lint, smeared or not with irritating ointments, is attended with much pain, and certainly impedes the cure. The dressing should be simple and light, and introduced with gentleness and care. The first should be allowed to remain undisturbed till spontaneously discharged along with the feculent matter. In the greater number of cases, a second interposition of dressing is all that is required. In all cases, dressing should not be continued long; but as the cavity gradually contracts, discharging laudable pus, and becoming coated with healthy florid granulations, the interposed pledgets should be daily diminished, and soon omitted entirely. If the surgeon continue long to stuff the wound it cannot contract, will become callous as before, and a fistula will be reproduced. Injections into the wound, or the application of lint soaked in a gently stimulating lotion, are often beneficial in promoting contraction. But, as already stated, most fistulæ get well after proper incision, with but one or two dressings, and without any after application excepting abundance of soap and water. During the cure, the general health must be kept vigorous, and the state of the bowels strictly attended to.
In ulcer of the mucous lining, with irritability of action in the bowel, injections of tepid or cold water are useful, by removing irritating matters from the part. By means of a speculum ani the ulcer can be readily exposed; it maybe touched occasionally with the nitrate of silver, in substance or solution, or, if very indolent, with a solution of the bichloride of mercury. When the irritation is very great, and the lower part of the bowel frequently in a state of spasmodic action, the sphincter may be divided so as to allow the parts to remain quiet; and anodyne suppositories or soothing enemata will then be used with much greater advantage than previously. To obtain reparation of breach of structure in any part, rest is a principal part of the treatment; and in the case of the rectum and other mucous canals it is preëminently required.
Strictures of the rectum are treated by bougies of wood, plaster, or elastic gum, introduced at intervals, and gradually enlarged. The bougie should be smooth in the surface, and rounded at the point; also slightly curved, so as to suit the figure of the bowel; and with a narrow neck, so as to remain without the irritation caused by distention of the sphincter. At first it should be of such a size as can without much difficulty be pushed past the stricture, and, as this relaxes, the size of the instrument must be proportionally increased till it completely fills the bowel when dilated to the natural calibre. The bougie may at each time be retained from a quarter of an hour to an hour, according to the feelings of the patient. Suppositories and enemata are at the same time employed; the latter to clear out the lower bowels, the former to allay the irritation which accompanies the disease, and which may be increased temporarily by the bougies. When the stricture is callous, and will not yield by dilatation, it may be divided with the knife, and notched at various points of its circumference; and, when the parts have begun to granulate, recourse to the bougie will soon effect a cure. When fistula and stricture coexist, both are got rid of at once by the usual operation for the former, and by the after treatment peculiar to each.
In malignant contractions of the gut, all that can be done is to palliate the disease by anodynes, administered by the mouth, or applied topically. Injections, bland, and occasionally anodyne, tend to diminish irritation; bougies aggravate the disease. At the commencement, the diseased parts may be removed by the knife or by ligature, and relief and exemption follow, at least for a time; but no operation is warrantable in this or any other cancerous affection, when the morbid action has gained ground, and the disease is extensive. Female patients have by some been cruelly treated; the vagina and diseased bowel have been laid into one loathsome cavity, and though the patients have continued to pass excrement and discharge through this cloaca, with the symptoms undiminished, themselves miserable and obnoxious to others—still such cases have been reported as cures!
