Part 59

_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.[48]

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.

Patients affected with hemorrhoidal swellings,—the action of whose bowels is irregular, and in whom the vessels about the anus are congested,—are peculiarly liable to inflammation and abscess in the rectum or its neighbourhood, from the application of cold or wet to the surface, particularly that of the lower part of the body. Ascarides often produce violent irritation in the extremity of the rectum, both in children and in adults; and the morbid excitation is communicated to the bladder, as will afterwards be noticed. Not unfrequently the inflammation is induced by a foreign body, either lodging in the cavity of the bowel or imbedded in its coats—as hardened feculent matter, alvine and biliary concretions, bones of small animals, needles, pins.

Effusion often takes place into the loose cellular tissue round the bowel, with hard swelling, followed by unhealthy and extensive suppuration. Rigors generally precede the formation of matter, and violent fever almost always attends, abating, along with all the painful feelings, on evacuation of the fluid. Still the discharge continues, and the patient is kept uncomfortable and unhappy. Resolution can very rarely be produced; suppuration is the almost uniform termination of the action, and in persons of bad habit this sometimes occurs in these parts without any assignable cause, and without previous warning. The purulent collections are often very extensive, both externally and internally, the integuments are all undermined, and in some cases it is difficult to ascertain the depth of the abscess, even with the aid of a long probe.

Owing to the loose nature of the texture surrounding the gut, abscesses near the anus often attain a great size, and extend deeply before there is much external indication of their existence; a hardness is felt on pressing the fingers deeply by the side of the tuberosity of the ischium; this is at first obscure, but gradually becomes more developed; and at last a small dark red spot appears, indicating that the matter has approached the surface, and is most superficial at that part. But the surgeon should not wait for the pointing here, as the matter may burrow much previously, and abscess form in the substance of the sphincter, or exterior to it. If the matter does not cause ulceration of the coats of the intestine, and escape into its cavity, pointing takes place, and the pus is discharged externally, in general through a small opening. The matter is of a very offensive odour. The external aperture, and even the whole cavity of the abscess, may be at a distance from the gut, but in most cases the matter is close to it: its coats are denuded, and often ulcerated through. The surrounding degree of induration, the quantity of contained matter, the extent of the cavity, and the situation of the opening, vary almost in every instance.

Cases occur of induration, often very extensive, in the neighbourhood of the anus, on one or both sides, with dark discoloration of the integuments, and burning pain. The affection resembles carbuncle. The precursory symptoms are soon followed by partial suppuration, and extensive sloughing of the cellular tissue. At first there is excitement of the system, but symptoms of debility, and flagging of the vital powers, soon present themselves—irregular pulse, delirium, disordered stomach, hiccough, vomiting, and cold extremities. The disease is one of great danger, and the patient can be saved only by free and early incision, and the judicious employment of stimulants.

In some instances the inflammation is merely superficial, seated merely in the integuments, and followed by slow collection of matter.

It is indeed seldom that a cavity formed by abscess near the anus fills up entirely, however large and free the opening into it may have been. The parietes contract, but the hardness around is not entirely dissipated; the opening may close for a little while, but is soon found again discharging, and may continue to do so for months or years. A sinus is thus formed. Fresh collections and openings, either externally or internally, are apt to occur, with extensive induration of the cellular tissue, and disease of the gut. Instead of a single sinus, a number of collateral ones are formed, all running into the main canal, like branches to a common-sewer, or by-lanes opening into one spacious street. The disease is one of frequent occurrence amongst females; and often from a false sense of delicacy its existence is not declared till it has advanced to a state of truly horrible perfection.

_Fistula_ is generally the consequence of abscess in the cellular substance near the anus. By the term is understood a sinus or track, with narrow orifice and hard parietes, discharging thin gleety matter. If the track extends from the cavity of the gut to the surface, flatus must often pass through the narrow and tortuous canal, and, from a peculiar noise being produced by its passage, the name of Fistula has probably been adopted. The term cannot be properly applied to recent cavities of abscesses, but only when their sacs have contracted, their lining has become callous, and their discharge thin and almost colourless.

The fistula may be one of three varieties—blind external, blind internal, complete. The first denoting that the sinus opens externally, but does not communicate, either at its origin or elsewhere, with the cavity of the bowel. The second, that it communicates with the bowel, but does not open externally. The last, that it both communicates with the bowel and opens externally. Some contend that fistulæ are always complete, that they commence from within, and that the internal opening is always at one particular point; but such, according to my experience, is far from being the case.

Fistulæ occur in children, though rarely; generally in people advanced in life. The cavity of the sinus, after long continuance, becomes coated with an expansion resembling mucous membrane, and secretes a discharge of mucous character.

In every case, it is necessary that the surgeon should ascertain, as accurately as possible, the extent and nature of the fistula; and, with this view, examination with the probe is requisite. The probe is introduced into the canal, when the fistula is an external one, and directed through its windings, so as to discover its direction, length, and divarications; the guidance of the instrument is facilitated, and the information augmented, by the forefinger being placed in the rectum. Sometimes all the by-paths cannot be detected, until the orifice of the canal is enlarged. When the fistula is complete, the probe, entered at the external extremity, can be passed into the bowel so as to be felt by the finger in the rectum; but it must be remembered that the internal opening is not always at the inner termination of the sinus, but often seated more externally—the cellular tissue being destroyed to a considerable extent above it, so as to form a large unhealthy abscess, communicating with the main track of the fistula. But the gut may not be opened into, though denuded to a large extent, and forming part of the walls of the sinus; and in some instances, the sinus may not come within a considerable distance of the bowel.

An internal fistula is more difficult of detection. The symptoms leading to a suspicion of its existence are—puriform discharge from the bowel, increased on going to stool, and then accompanied with tenesmus; pressure on the side of the anus, causing pain, and sometimes an augmentation of discharge; and in many instances hardness, deeply seated, is felt. On introducing the finger into the rectum, the aperture in the coats of the bowel is perceived, or a part of the bowel feels more boggy and tender than the rest; through this point a curved probe, introduced along the finger, may be passed into the sinus, and being then directed downwards, reaches the outer extremity of the canal, causes the integuments to project, or is readily felt from the surface. The internal opening is usually immediately within the sphincter, seldom higher.[49] The discharge, in general, is rather profuse, the bowel is very irritable, desire to evacuate it is frequent, and the feces are often tinged with blood. There is a sensation of itching about the fundament, the heat of the parts is felt by the patient to be increased, he is unable to bear pressure there, and sits on one buttock: in most cases the bladder sympathises considerably. The giving way of the bowel may be produced by ulceration commencing in the mucous membrane, but is more frequently the result of inflammatory action in the surrounding cellular tissue. The aperture is the seat of acute pain when pressed upon, and during evacuation of the bowel. Great light is thrown on such cases by the use of a proper speculum. But its introduction can seldom be borne in cases of inflammation, abscess, or recent fistula. In ulceration of the coats within the sphincter it is useful. Considerable information can certainly be obtained by the finger; but to the sense of touch, however acute, it is better, when admissible, to add that of vision. The speculum, made of silver or steel, and having its internal surface highly polished, is introduced gently into the anus, and expanded fully; and by changing the situation of the instrument, and holding a light so as to illuminate the interior, the surface of the bowel for five or six inches above the anus can be examined accurately, as if it were an external part of the body.

Simple indurations and contractions of the lower part of the bowel follow long-continued irritation and inflammation of its parietes. The part is not an uncommon seat of stricture, and sometimes the bowel is constricted at two or more points near each other; frequently the stricture is extensive and firm, in other cases it is narrow, consisting merely of a thin band. It is often complicated with fistula; if so, the internal aperture is immediately above the stricture, and is caused by ulceration; abscess sometimes forms above the stricture, destroys the coats of the bowel at that point, burrows around, and not unfrequently points at a great distance from its origin; or sloughing and ulceration may take place in the coats of the bowel, and feculent matter be discharged through the opening of the abscess. In females, the vagina may be opened into in consequence of unhealthy suppuration in the cellular tissue, between that organ and the gut.

The existence of stricture is in general readily ascertained by examination with the finger; its most common situation is here shown; the medical practitioner must not suppose that every obstruction, however slight, to the passage of a bougie into the bowel is owing to organic disease; the top of the sacrum naturally projecting forwards on the commencement of the rectum, in some degree opposes the entrance of any large body, and this circumstance is laid hold of by the unprincipled or ignorant; the patient is very often declared to labour under stricture of the bowel, when none exists. Some practitioners discover stricture in almost every patient with disordered digestion; the whole digestive apparatus is certainly thrown into disorder by obstruction in the lower part, but this obstruction is fortunately rare. In cases of tight stricture, the bowels are distended with feces and flatus; and if evacuation is not procured vomiting ensues, followed by enteritic symptoms, as in strangulation of the higher bowels. The gut above the stricture is always more or less dilated.

The symptoms which lead the surgeon to suspect the existence of stricture, are—difficulty in voiding the excrements; a long time occupied in the evacuation, with pain and much straining; small thin portions of feculent matter coming away, when the matter is consistent; discharge of puriform fluid, mixed with a slimy mucus; itching and heat in the parts; and irritability of the urinary organs.

Strictures of the urethra and rectum often coexist, as exemplified by the following case:—A middle-aged man, when in Holland, laboured under a very deep and extensive fistula in ano. Sinuses were divided in all directions, and some healed; one, however, remained open, leading towards the gut from near the tuberosity of the ischium on the left side. He was desired to keep this open by means of bougies, which, as many were used, he manufactured himself out of cloth and plaster. On one occasion a portion passed deeply, and could not be extracted; but his alarm at this occurrence was appeased on being told that the foreign body would be absorbed. His condition at that time was very miserable; and inflammation was often excited in the parts, with fresh collections of matter. At the same time, he laboured under stricture of the rectum and urethra. He applied to me fifteen years after the commencement of the disease. Then the most troublesome symptom was a constant itching in the perineum, and round the anus, preventing sleep, and causing much excoriation from involuntary scratching; besides, he was annoyed by seminal emissions, and frequent desire to make water. I first divided a small internal fistula, and some time afterwards operated on a large complete one; in the latter instance, a foreign body was felt deep in the wound, the incision was extended, and a large portion of bougie, firmly impacted, was with some difficulty withdrawn. Some days after, other portions of bougie were extracted along with numerous hairs; and these continued to be discharged for many weeks. The symptoms were much relieved. An occasional itching remained, but disappeared after the cure of a very bad stricture in the urethra. He recovered perfectly from the complication of diseases.

_Schirro-contracted Rectum_, a malignant and truly horrible disease, may be the consequence of inflammatory action, or of neglected stricture. The neighbouring parts are involved in cartilaginous induration; the surface of the bowel is lobulated and ulcerated, its cavity is contracted, and the discharge is profuse, sanious, bloody, and putrid; there is frequent desire to void the contents of the gut, but in general nothing but flatus and puriform fluid is evacuated; when feces do pass, dreadful pain is excited, and continues for some time. The difficulty of voiding feculent matter becomes greater and greater, frequent attacks of ileus occur, and in one of them the patient expires. During the progress of the disease, the functions of the bladder become disturbed; change of structure in it and in the vagina takes place; and frequently the cavities of the rectum, bladder, and vagina are laid into one by inveterate and malignant ulceration. The affection is more common in females than in males, and rarely occurs in young persons. The countenance has the sallow hue peculiar to carcinoma, and in the advanced form of the disease becomes still more cadaverous from profuse discharge of matter and frequent hemorrhage.

The cellular tissue, anterior to the rectum, is liable to become the seat of tumour. Malignant medullary formations occasionally form here, causing most distressing symptoms; by displacing the bowel they may obstruct its canal, and simulate stricture or schirro-contraction.

_Prolapsus Ani._ Folds of the lining membrane of the lower portion of the rectum are apt to protrude during evacuation, as already mentioned, in those labouring under hemorrhoids. These are readily replaced, and the painful feelings relieved, if the attempt be made before swelling and engorgement of the vessels and cellular tissue take place. Protrusion, however, is sometimes to a great extent; the sphincter is relaxed, and the lower part of the bowel is retained within it with difficulty; indeed there is often more of the lining membrane of the gut without the sphincter than within it. The mucous lining becomes insensible, thickened, and white; and the patient is subject to attacks of inflammation, with additional swelling, excoriations, and ulcers of the parts. Slight protrusion is very common, and patients who have long laboured under it are in the habit of reducing the bowel after every stool, in the intervals wearing a supporting bandage. They are subject, however, to constant uneasiness, and more or less puriform discharge from the parts; often there is a flow of blood while at stool; the health is undermined, and comfort diminished; all exertions are gone through with difficulty, and undertaken with reluctance. During exertion protrusion is almost certain to occur, and apt to be increased. The part most commonly prolapsed in time becomes hard, thick, and in a measure insensible; and new folds appear on extraordinary straining at stool, in coughing, or any exertion of the abdominal muscles.

Tumours occasionally grow from the coats of the rectum, and are of various consistence. They may be either vascular, or deposited in consequence of increased vascular action, and afterwards increased by addition of solid matter. They are to be removed either by ligature or incision, according to their situation, nature, and attachments.

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.
