As a rule, the symptoms which have been diagnosed as those of chronic mucous colitis, membranous colitis, or ulcerative colitis are nothing more than symptoms of chronic mucous proctitis and sigmoiditis, accompanied by periproctitis and perisigmoiditis. Proctologists who have written on the subject of mucous colitis have noted the many symptoms very accurately, but have missed the usual location of a most aggravating disease from which mankind suffers early and late in life. Authors of books on stomach and intestinal troubles are also groping very much in the dark and are unable to diagnose the cause of a very common functional disturbance of the whole digestive apparatus, caused by proctitis and sigmoiditis, bringing numerous and severe primary and secondary symptoms to which other diseases may be traced. Chronic proctitis and sigmoiditis and their local symptoms convert the sigmoid receptacle into an Augean stable, from which foul poisonous gases and germs are forced up and along the bowels, distending the descending and transverse colon and finally reaching the ascending colon and the cæcum, causing undue retention of their contents; hence so much attention to the cæcum and the vermiform appendix. The ends of a long rubber tube distended with gas will exhibit more strain and disturbance than the intermediate parts, and the same is true of the colon, owing to the intermediate sections of the organ possessing greater mobility. The great volume of gases confined in the colon prevents its normal peristaltic action, causing undue retention of contents, with resulting inflammation of the cæcum, as well as dislocation of the stomach, colon, etc., and suggesting radiographic and fluoroscopic examination and surgical operations to discover the cause of all the trouble, which should have been learned through use of the speculum before so many complications occurred. In all cases of chronic mucous proctitis and sigmoiditis where there is a great amount of secretion of mucus, membranous cords, shreds, and casts (called mucous colitis), I have found the marked acute symptoms more or less periodic and accompanied by increased inflammation in all the tissues involved in the disease, which convinced me that the colitis we read about had become dislocated and was where I could see its results without the use of a speculum. Through often witnessing the phenomena, I have learned what a “mucous colitis” storm means from a pathological exhibit, a personal demonstration, and a verbal description of what the sufferer is enduring. It requires the stuff heroes are made of to endure chronic mucous proctitis and sigmoiditis for ten, thirty, or forty years without the disease being accurately diagnosed, and to be told that all treatment is useless and that the trouble is in the head of the sufferer, that he is a hypochondriac, and a neurasthenic, terms often used by doctors who are unable to make a proper diagnosis of a case.
