Part 43

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.

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.

As already hinted, the operation of tapping the abdomen is to be undertaken only when the distention is very great, when the functions of the thoracic and abdominal viscera are interfered with, and when diuretics, and other means of getting rid of the fluid, have failed to diminish the accumulation. The trocar employed is either flat, with a spring steel canula, or round; when the latter is used, and the abdominal parietes are not very tense, a small incision is first made with a lancet or bistoury; a large trocar with blunted edges and point can then be readily and safely introduced; the flat one enters easily, and requires no previous wound, but does not permit so rapid and free a flow. The point usually chosen for the puncture is either in the linea alba, a little below the umbilicus, the bladder being previously emptied,—a precaution which should always be attended to, though in general there is little danger of wounding this organ—or midway betwixt the superior anterior spinous process of the ilium and the umbilicus, with the view of penetrating the parietes in the linea semilunaris. The latter situation, however, can seldom be obtained with accuracy, for the parietes yield irregularly. Little bleeding follows the puncture at either point; but the risk of hemorrhage is greater at the latter, for branches of the circumflex artery may be wounded. More serious bleeding is liable to occur, from the veins ramifying on the abdominal viscera giving way, on removal of their support, as the serum flows off. Fainting, also, may take place from accumulation in the branches of the vena portarum, unless the fluid is withdrawn slowly, and the precaution adopted of supporting the parietes with a broad band both during and after evacuation. Bandages are made for this purpose, with tapes and straps attached, and are well fitted for it. Three or four yards of flannel, however, with each end split, are equally effectual, and can always be readily obtained—a consideration of consequence in the choice of all apparatus. After the band has been applied, a person is placed on each side to tighten it gradually by steady pulling at the ends, which are carefully crossed behind. An opening is made in the cloth, opposite to where it is proposed to puncture, and the operation is then proceeded in. Sometimes the flow is impeded by the omentum or a fold of bowel falling forward on the canula, and closing or diminishing the opening; this is remedied by passing a tube along the canula, closed at the extremity, but perforated at the sides near it, and about half an inch longer than the canula. After the cavity has been emptied, the patient is placed recumbent, and a long broad flannel bandage applied over the whole abdomen, and retained, so as to prevent shifting, by straps passed over the shoulders and under the perineum.

Collections occur in the ovaria. The fluid is generally glairy, sometimes thick and gelatinous, often turbid and dark coloured. Not unfrequently the main cyst is subdivided, either by membranous septa, or by an aggregation of smaller cysts of the nature of hydatids. The swelling is at first on one side, and gradually rises out of the pelvis; often it remains long moveable; it increases, becomes more fixed, and ultimately fills the abdomen, displacing the viscera, and giving rise to feelings of much uneasiness, deformity, and loss of health. The cyst is generally thick; sometimes it is thin at one or more points, and this may give way, causing effusion of the contents into the peritoneal sac. Fluctuation is perceptible in many cases; in others it is obscured by the thickness of the cyst and viscidity of its contents. Many such swellings may be punctured both with advantage and with safety, but generally the tapping requires frequent repetition. Some patients require tapping, merely as a mean of improving the figure and relieving uneasy feelings, once, twice, or thrice a year; their existence is not much embittered or abridged by the disease. A large round trocar is necessary for the purpose; and the puncture is made at the softest and most prominent point of the tumour, a small incision through the integument being premised.

The ovaria become enlarged by degeneration of their structure and the addition of solid matter in great abundance. The consistence and structure of such tumours are very various; they are sometimes, though rarely, medullary, often fibrous, with or without cysts, sometimes melanotic. In the majority there are cysts, varying in size, number, and contents; sometimes the bag contains hydatids, or it is filled with curdy matter, sometimes with glairy colourless fluid, sometimes with a turbid and flaky serum, sometimes with blood; and in them, as well as in the enlargement from accumulated fluid, though perhaps more rarely, are occasionally found teeth, hair, and membranous looking matter; some are intermixed with bone, cartilage, and fat. The situation and attachments of such tumours cannot be correctly ascertained by examination during life, far less can their internal structure and dispositions be arrived at. Indeed an accurate diagnosis is exceedingly difficult, if not impossible. Innumerable mistakes have been made, which have led to most unjustifiable proceedings. In one case, the abdomen was, after two or three dry tappings, opened by an incision from the ensiform cartilage to the pubes; the viscera were turned over and over, but no tumour could be discovered. The woman was sewed up, and did not die. The following was a still more complete failure in diagnosis. In a case of large tumour of the belly, many persons accustomed to manipulate abdominal swellings considered that extra-uterine conception had taken place; and that the child had come to maturity and perished. The history of the case countenanced the supposition; the symptoms had been such as indicate impregnation. The woman, to avoid exposure, went to a distance to be relieved of her burden, which was becoming more and more troublesome and bulky. The usual period passed over. It was thought that the head and thorax of an infant could then be felt readily through the parietes, and perhaps some one might have been found heroic enough to have divided them and explored the tumour. The young woman, however, was in the last stage of phthisis, and soon died. A wonderfully tuberculated omentum, a very small portion of which is here represented, filled the peritoneal cavity; the uterus and its appendages were quite healthy.

Operation has also been proposed, when, on dissection, the liver was found to compose the abdominal swelling. Such cases, a long list of which might be given, render the prudent surgeon very cautious in his diagnosis of abdominal tumours, and chary of operative interference with them. The abdomen has been opened, as already stated, and the result has been such as to render the perpetrator indictable for culpable homicide, and to qualify him for such punishment as his rash and reckless conduct richly deserved. A less severe censure might have sufficed, had not the example been followed by similar proceedings, and equally direful results; and these have been such as to render any condemnatory remarks not only justifiable but absolutely necessary. A great many unfortunate women have, I am afraid, been sacrificed to a desire for false reputation. The attempts to remove abdominal tumours by incision of the parietes were some time ago very numerous; and, as might have been expected, the issues were highly unsatisfactory to those concerned. Such doings, however, were recorded in print, represented in plates, and moreover puffed and placarded ad nauseam. The majority of those who were thus “dissected, to see what part was disaffected,” perished within forty-eight hours. One woman survived for some time, after having been subjected to this operation, improperly so termed. In her there was a tumour, but of such a size, and so connected, that it could not be removed. A second survived the extirpation of one ovarium; and the other, also diseased, was left for a further exhibition of daring intrepidity. It is not easy to conceive how the proposal could have been seriously entertained by any sane individual, far less put in practice and persevered in, when disaster after disaster crowned every attempt. It is my opinion, and I believe that I express the sentiments of a very large portion of the profession, that the repetition of any such incisions and gropings would be unpardonable.—1. On account of the difficulty, nay, impossibility, of forming a correct diagnosis; of ascertaining with certainty what organ is involved; of ascertaining the structure and disposition of the tumour, if any, and to what parts it is adherent. 2. Because the ovarian disease, in general, even though extensive, does not threaten imminently a fatal termination, being slow in its progress, and the greater number of the swellings being not of a malignant nature. The solid tumours are sometimes of a bad kind, as already stated; but enlargement by fluid is much more frequent in the ovaria than that by solid and new matter. 3. If the tumour be malignant, it will be impossible to ascertain to what extent the parts are involved by the diseased action, or whether the lymphatics are affected or not. There is a strong probability of the lymphatic system being involved, even at a very early period; and then the extirpation of the tumour—supposing the mass to be so situated as to admit of removal without difficulty or danger—cannot be attended with any advantage; in every point of view, therefore, interference is unadvisable. 4. The operative attempt is attended with imminent danger. There is almost a certainty of the patient being almost instantly destroyed by it, as shown by the sad experience of the past. “We are not the arbiters of life and death of those who apply to us for relief. If people die in consequence of disease, it cannot be helped. They submit to it because they know it is inevitable. But we had better refrain from making such experiments as may probably destroy them, and bring disgrace upon the profession.”

Bruises of the abdomen are apt to be followed by inflammation of the contained parts, particularly of the serous membrane. Occasionally lacerations of the viscera, both solid and floating, but more frequently of the former, are produced by bruising or squeezing of the abdomen, as by a blow, or by a heavy body passing over; they may also follow a violent concussion of the parts by falling from a height. The liver is the organ most frequently torn, and death is commonly the result, rapid, and principally from hemorrhage. The laceration is generally on the convex surface; extravasation takes place under the peritoneal covering; or this is torn, and the effusion is into the abdominal cavity. When the quantity of blood is not so great as to cause speedy dissolution, the patient may survive for some time, and even ultimately recover. Reaction is slow, the patient continuing a long time pale, exhausted, and almost pulseless; there is tenderness in the hypogastric region, with swelling. The spleen is liable to similar injury, and pours out a large quantity of blood.

The gall-bladder has sometimes been torn, as also portions of the small intestines, by a blow or kick, or by a heavy body passing over the abdomen, as the wheel of a loaded wagon. The escape of the contents is followed by sickness, rigour, quick, weak, and indistinct pulse, most excruciating pain, a sense of heat diffused all over the abdomen, and rapid sinking of the powers of life; a fatal termination generally occurs within twelve hours. The same train of symptoms supervene when the contents of the intestinal canal have been effused into the peritoneal cavity, through an opening in the stomach or bowel, caused either by slow destruction of the coats, the peritoneum giving way last, or by a rapid ulceration or sloughing process, as in hernia. The patient may live in agony for a day or two, but death generally takes place much within twenty-four hours. The same may be said of the rupture of the bladder, from external violence, with effusion of urine into the peritoneal sac. No treatment is of any avail; venesection hastens the sinking. Fomentation over the abdomen, and sedatives either by the mouth or by the anus, soothe the patient, and render his last moments more calm.

Penetrating wounds of the peritoneal cavity, if they reach the solid viscera and large vessels connected with them, are attended with effusion of blood externally and internally, in quantities proportioned to the size of the external aperture, the importance of the vessels concerned, and the vascularity of the part. The patient may perish from the bleeding, either instantly or after some time; or inflammation and its consequences supervene in the violent form, and destroy him at a more remote period. The mere opening of the peritoneal cavity, and to a very slight extent, without the slightest injury of the contained parts, is often attended with a great shock to the system, and is followed by inflammatory action, which may run on to a fatal issue, in spite of the most active and judicious management. The inflammatory symptoms are to be combated by free abstraction of blood; in short, the utmost endeavours must be made to keep the action within bounds. When the intestines are wounded, the injured part may protrude; or the relative size of the openings through the parietes and bowel may be such, that the intestinal contents do not escape into the peritoneal bag. A natural cure sometimes takes place by adhesion of the surface of the bowel to the lining of the parietes round the wound, feculent matter continuing to be discharged externally; after a time the opening may contract, and the discharge diminish and ultimately cease; or an artificial anus may be permanently established, and this is not so easily cured as that following upon hernia. Wounds of the intestines, whether transverse or longitudinal, attended with feculent escape into the peritoneal cavity, are not uniformly fatal. Effusion of lymph takes place around, gluing the wounded bowel to the peritoneal surface of a neighbouring fold, or forming a sort of pouch within which the extravasation is limited. The treatment consists in absolute rest, and most rigid antiphlogistic regimen; manual interference with the wounded part is not generally advisable.

Lumbar Abscess is generally chronic; the collection of matter is gradual and slow. Sometimes it is acute, and rather rapid in its appearance. It may originate in the sheath either of the psoas or of the iliacus muscle; more frequently it seems to form behind these, and is connected with diseased bone. The precursory symptoms are often not particularly attended to; these are rigors and pain of the loins. As the disease advances, the patient feels great pain in the erect position, and in general the pain is aggravated by extending the thigh. Thickening and slight glandular enlargement takes place in the groin; there is an evident fulness there; and then swelling appears on the inner side of the femoral vessels, beneath the pubal portion of the fascia lata. This swelling is more prominent in the erect position, and is also increased by exertion of the abdominal muscles; an impulse is given to it on coughing. As it advances, and comes more to the surface, fluctuation is perceived. This is the most common site in which the abscess presents itself; but it is not unfrequently met with on the outside of the vessels, either lower or higher in the thigh, above Poupart’s ligament, in the loins over the crest of the ilium, and occasionally the matter is insinuated under the pelvic fascia and appears by the side of the anus. Large and neglected collections may work their way to the surface in two or three of these situations at the same time.

The disease is often attributable to a sprain or wrench of the loins, or to exposure to cold and over-fatigue. Occasionally the mischief is confined entirely to the soft parts; the vertebræ, a portion of the os innominatum, or the sacrum, may be denuded and of irregular surface, but this is evidently the result of the pressure of the abscess. A striking example of this, and of the extensive destruction of parts which this affection sometimes produces, may be shortly stated.—A very large lumbar abscess formed within a few weeks, in consequence of great and continued fatigue and exposure to bad weather. At first it had been trifled with. At last it was opened in the usual situation in the thigh, and a vast quantity of matter evacuated. Thirty-six hours afterwards, the patient was suddenly suffocated by a flow of purulent matter into and through the air passages. On dissection, the cavity of the abscess was found to be immense, opening through the diaphragm into the lung which was adherent, and communicating with the bronchi. The forepart of the lumbar vertebræ was exposed, and in some parts stripped of the theca; but there were no cavities in the bone, and no disease of the interposed cartilages. Such cases are now and then met with, of abscess in the loins not originating in any vice either of the bones or of any other part of the apparatus of the spinal column. Most frequently, however, the collections have their foundation in ulceration of the bodies of the vertebræ. The patient has had tenderness in the part, weakness of the back and of the lower limbs, and increase of pain on pressing or striking some particular spinous processes—perhaps slight excurvation. Then pain in extending the thigh supervenes, followed by swelling and other signs of abscess. This is preceded generally by deposit of tubercular matter in their cancellated texture. Sometimes the disease seems to originate in the ligaments and articulating surfaces; occasionally portions of the bone perish, and are found lying in the cavity of the abscess, as seen in this specimen, taken from a young subject. When the bodies of the vertebræ are attacked by ulcerative absorption, and sometimes the disease is very extensive, involving perhaps four, five, or six of the bones, there is more or less curvature of the spine outwardly—excurvation. If the disease affects one or two bones, and their bodies are almost destroyed, then the projection is sharp and angular. When the disease is more extensive the curve is greater, and more gradual ulceration sometimes exists to a considerable extent in one articulation, without change of form externally in the spinal column, and sometimes without any great collection of pus. When curvature commences there is very generally more or less weakness of the limbs, though curvature, whether from ulceration or interstitial absorption, is by no means of necessity attended by any degree of paralysis. The power of motion of parts supplied by nerves in the neighbourhood of disease is diminished earlier in general than the sensation, in consequence, possibly, of the mischief commencing in the anterior part of the bodies of the vertebræ. It is wonderful to what extent disease may extend in the vertebral column, without much impairment of the functions of the spinal chord, and how perfectly the functions are restored in cases where it has suffered. The lumbar vertebræ are those most frequently affected, but the ulceration may also be either in the dorsal region or in the pelvis. Disease of the last lumbar vertebra at its connection with the sacrum, or disease of the sacrum itself, is attended with abscess around, which descends into the pelvis, displacing the bowel, and appearing by the side of the buttock.

Such abscesses may have been allowed to come to the surface, and to discharge their contents spontaneously; or they may have been at a late period opened either at one point or at several. In these circumstances, the discharge is generally profuse, long-continued, and attended with exhaustion and hectic, gradually but surely destroying the patient. But, by good management, a perfect and permanent recovery may in many cases be obtained. When the vertebræ are affected, absolute rest must be enjoined and enforced; and a drain is to be established by the sides of the spinous processes, either by moxa, potass, or seton—it is immaterial which. The discharge is kept up by occasionally dressing the issue for a few hours with an acrid ointment, so as to reproduce a slough. When the abscess begins to present, it should be opened as early as possible, and a free exit allowed to the matter; the discharge should be at no time confined. The opening of the cavity, and again shutting it up, however carefully conducted, is in almost every instance followed by alarming and hazardous results. Rapid accumulation of putrid and bloody matter takes place, and air is extricated within the cavity; the vessels of the cyst, being unsupported, part with their contents; irritative fever is lighted up, with rapid pulse, anxious countenance, and delirium. These symptoms are relieved only by immediate evacuation of the fluid. Some slight constitutional disturbance follows the making of a free opening, but quickly subsides; then the discharge improves in quality, becomes more pure and unmixed, diminishes in quantity, and gradually ceases. During the discharge the strength requires support; and the attention to the original mischief must not be neglected or intermitted.

Spina Bifida is a congenital fluctuating tumour, with deficiency of the subjacent vertebræ. It is usually situated in the lumbar region, sometimes in the dorsal, and often over the sacrum. The size of the swelling varies according to the age of the child, and the extent of deficiency in the parietes of the spinal canal. The spinous processes are either imperfect or altogether wanting, and over the space so formed the tumour is situated. Its contents are usually of a serous character, thin and colourless; sometimes they are turbid and flaky. The parietes seem to be a continuation, or protrusion, of the membranes of the spinal chord, thickened and somewhat altered in structure, and usually in close contact with and adherent to the integuments. By pressure the size of the tumour is diminished; but, if firm or long continued, unpleasant effects are apt to result. There is often debility of the lower limbs, and the disease is not unfrequently coexistent with hydrocephalus. Children with this affection seldom live more than a few years.

The application of gentle, uniform, and continued pressure affords support to the parts, and prevents increase of the tumour; and, under this palliative treatment, life may be both rendered more comfortable and prolonged. It has been proposed to combine continued pressure with occasional puncturing of the cyst by means of a fine needle, with the view of diminishing the tumour and ultimately obtaining entire obliteration of the cyst. The practice has been made trial of, and the result may warrant repetition; caution, however, is necessary, for the too free opening of the tumour is often followed by a rapidly fatal issue. A case occurred to me not long since, in which the tumour, of large size, was situated over the sacrum. The fluid was evacuated by a small trocar and canula, the parietes shrank, and a very satisfactory cure resulted.

AFFECTIONS OF THE RECTUM AND NEIGHBOURING PARTS.

Of Hemorrhoids or Piles.—Piles are blind, furnishing no discharge, except a mucous or puriform fluid; or open, pouring out a greater or less quantity of blood from time to time. They are usually of small size, invested by the mucous membrane, thickened, congested, and consequently of a dark colour; and either within the sphincter or projecting externally. Internally, they may sometimes consist of blood, coagulated or not, effused between the mucous and muscular coats of the intestine; but in general their inner structure is venous, at least in the first instance. Branches of the hemorrhoidal veins, ramifying near the inner surface of the gut, become varicose, probably from their superior trunks being compressed by hardened feculent matter or other obstructions. The varix protrudes the superimposed mucous membrane; and at first the excrescence is composed of the dilated venous trunks containing fluid blood, and invested by the membrane, which inflames, thickens, loses its villous character, and discharges a vitiated secretion. In this stage the tumour is easily compressible, and by pressure may be made to disappear almost entirely, the communications between the varicose vessels and the trunks above being still unobstructed. But inflammatory action is soon kindled in the incommoded venous branches, as frequently happens in varix of the lower extremities; their coats become changed, are thickened, effuse lymph externally and internally, adhere to one another, and are ultimately matted into one confused and solid mass; the contained blood coagulates, becomes fibrinous, the whole tumour feels hard and firm, and often is exceedingly painful. At length all traces of venous structure disappear; the tumour seems to consist chiefly of effused lymph, condensed cellular tissue, and coagula.

In not a few instances, however, the contents of the veins remain partially fluid, and a communication exists between the vessels of the tumour and those of the surrounding parts.

That such is the usual structure of piles I am convinced, from repeated and careful dissection of the tumours.

The neighbouring parts often swell and inflame. Sometimes one or two tumours only exist; or they occur in numbers, clustered together, and form a large irregular mass, inflamed, and often ulcerated. Acute pain is experienced in the part, when touched and after straining at stool; by straining too, such as are attached within the sphincter are pushed out, together with folds of the mucous membrane, and, if allowed to remain, are constricted by the sphincter, swell in consequence, ulcerate or slough, and discharge blood. The bleeding often is very violent in such cases, or when the tumour is punctured; the blood flowing in great quantity, and in a rapid stream. The hemorrhage is often periodical, both in males and females; in the latter, it would seem occasionally to take the place of the menstrual flux. The soft bluish tumours that are compressible, and fluctuate when large, furnish blood more readily and profusely than the hard and tuberculated.

Much irritation is produced by piles, and some of them are more irritable than others. There are often extensive excoriation of the nates around, and profuse discharge from the raw parts, particularly when the tumours are external. In such cases, flat, hard, warty excrescences often form in the cleft of the nates, and increase the irritation; and these are termed fici, mariscæ, and condylomata.

In internal piles, a frequent desire to go to stool is induced, and more or less of the mucous coat of the rectum is protruded and swollen. The tumour, along with the protruded portion of bowel, may become strangulated if not replaced. By such or other causes inflammation is excited, which often extends to the neighbouring parts, and terminates in abscess; but this is not so apt to occur from tumours seated high in the rectum as from those about the verge of the anus.

The usual cause of piles is obstruction to the return of blood in the hemorrhoidal veins; and this may be occasioned by advanced pregnancy, habitual distension of the colon and sigmoid flexure, with hardened feces, or tumours of the abdominal viscera.

Inflammation of the Rectum is attended with excruciating pain, burning heat, and a feeling of contraction, increased very much when the parts are thrown into action by evacuation of the contents of the bowel, or of the bladder. The heat may be felt on introducing the finger, with the view of examination; by doing so, dreadful torture is produced, and such manipulation should not be had recourse to unless there is a suspicion of foreign matter lodging in the part, by removal of which the action might be cut short. The bladder is often affected sympathetically; there may be frequent desire to empty it, or else retention of its contents: this latter occurrence not unfrequently follows operations on the bowel, as for the removal of hemorrhoids, by ligature or extensive incision, which is neither warrantable nor requisite. The inflammation extends to the cellular tissue round the rectum, with swelling and increased pain; the pain is aggravated by pressure, and the patient is unable to sit erect. As the painful symptoms abate, puriform discharge from the membrane of the gut takes place, and often is very profuse. The morbid action sometimes extends to the other intestines, attended after a time with mucous or even bloody evacuations. When the affection is confined to the rectum, the feces and vitiated secretion are distinct from each other, and the former are usually of their natural appearance; but when the other intestines participate, to a greater or less extent, the feces are fluid, and intimately mixed with the morbid secretion.

Ulceration of the mucous coat, with continued discharge, often supervenes. Sometimes the peritoneal coat of the bowel is affected secondarily, and then the pain is much more acute and more aggravated by pressure.
