To introduce a new order of conduct on the part of the bowels requires time. If the bowels have been in the habit of expelling feces in the morning, and an enema were taken the night before, there might be no desire to stool the next morning because of the fact that the bulk or accumulated mass of excrement was no longer there to create a vigorous call or impulse for defecation.
But we have found the extent of local damage and reflex injury to the organs, and more especially we have found the constant absorption of poisons into the system, due to the presence of feces. It is for this reason that the elimination of feces twice or thrice in twenty-four hours is advised. The condition for which an enema is used is disturbing and poisoning to the system. It is, therefore, a most unnatural condition. What is more rational, then, than to employ an “unnatural” yet not harmful means to bring about a more normal condition, one free from poisoning and irritating consequences?
A fifth objection is made by those who have as a symptom of proctitis a large development of pile tumors or hemorrhoids (distended mucous membrane). The objection is that at times these tumors or sacs prolapse very freely during the act of expelling the injected water. But this prolapse occurs in many cases whether water is used or not.
A certain amount of anal irritation caused by the passage of feces occurs, causing contraction of the circular muscular tissue that forms the anal and rectal canal, also of the longitudinal muscular bands and the levator muscles of the organs. The enema lessens or entirely diminishes the irritation of passing feces, and the natural result is that the serum-filled sacs called piles and the tissue loosened by the inflammatory product would more readily prolapse during the act of defecating. It is simply a choice between irritation of the stool keeping the tissue up and no irritation permitting a prolapse.
Of course, if there be no expulsion of feces and water the stretched or dilated sacs may keep their places in the rectum. And then again the enema may be used for quite a period, when all at once a large prolapse of sacculated mucous membrane occurs, and the enema is thought to be the cause of it. That this is not the cause, let it be remembered that in all cases of proctitis the chronic inflammation is apt to become subacute or acute, and that this intense engorgement and enlargement of the tissue with blood and the increased fever in the parts often result in prolapse at any time, especially at times of convulsive effort at evacuation.
Whatever follows the proper use of an enema, even though what follows be annoying, should not be blamed on the enema, for its action is most kindly, lessening, as it does, the irritation that otherwise would be more severe when the feces pass through a disease-constricted canal.
The sixth objection is that the use of the enema will weaken the bowels, which are already too “weak” to expel their contents. “Atony, paralysis, fatty degeneration of the gut, are bad enough,” say these objectors, “without having an enema increase their uselessness.” Diagnosis wrong and objection groundless!
Distend and contract an organ for a short time two or three times a day, and it will gain in strength from the exercise. Every one knows that this is the case. What more gentle means of exercising the large intestine than by the enema?
But the truth of the matter is, that in all cases of proctitis and constipation the diseased portion of the gut is too active in its muscular movements, contracting spasmodically, as it does, at even the suggestion or suspicion of feces near it. Every impulse of the bowels above the constricted section to force the feces down through the closed bore only intensifies the spasmodic action and increases the muscular obstruction, compelling the victim to resort to some one of the many drastic means of relief.
The enema does no more than kindly to dilate the constricted region, which, when dilated, evokes a harmonious concerted action of all the nerves and muscles to pass along and down the burden of feces, which, without the aid of a flood of water, they had been incapable of moving, and would have had to leave to poison the system.
