“ The constriction is especially severe at the junction of the rectum with the sigmoid colon, where it flexes upon itself in the region where the bore of the rectum is less. The comparative shutting up of the caliber of the upper end of the rectum and lower portion of the sigmoid colon occasions undue retention of the feces and gases which accumulate, and in accumulating dislocate various portions of the large intestine, thus forming pouches, sacks, reservoirs, prolapse, etc., which hold the products of putrefaction as well as the irritating, poisonous mucus thrown out from the inflamed tissue. ”
