Dilatation of the Rectal Pouches, or Physick's Encysted Rectum
This is an uncommon disease, generally occurring in those advanced in years, and consists of an hypertrophy, and sometimes of an inflammation, of the natural rectal sacs. These pouches are quite small in early life, and enlarge gradually as age advances, this condition being favored by the lodgment in them of extraneous substances, such as indurated fecal matter, inspissated mucus, the seeds of fruit, and other undigested masses. Constipation, so usual with the old, predisposes to this affection, as it keeps the bowel distended with hardened feces. The pouches vary much in size, the largest of them admitting the end of a finger. The disease is insidious and slow, but is capable of producing intense suffering should inflammation, suppuration, or ulceration attack them. Sometimes as many as a dozen are involved.
The symptoms, which are rather misleading than suggestive of the disorder, are a sensation of weight and uneasiness just within the anus and uneasy sensations in the rectum, distressing itching, and, after a time, pain following defecation and lasting often for hours. The pain, which is aching and burning in character, is not confined to the parts affected, but radiates down the thighs, toward the back, and into the perineum. An increased secretion of mucus always exists in these cases, but the discharge of purulent matter is uncommon, and its presence indicates the existence of very active inflammation.
It is said that even in the worst cases no spasm of the sphincters occurs. An exploration of the bowel with a blunt-pointed hook affords the only reliable guide to correct diagnosis: this, as it is moved about in the rectum, engages the rim of a sac, which may thus be drawn down through the anus and examined.
