Thirty cases of rectal procidentia underwent various operative procedures were reported. The incidence rose to a peak in the third decade in both sexes but there was another peak in the seventh decade in the female. In contrast to the fact that the disease is more prone to occur in the female in Europe and America, there were more male patients in our series as in most of the Japanese reports. There was an unusual case, a 16-year-old male patient, who had procidentia with particular form of rectial adenomata in association with. abundant retcal secretion resulting in hypoproteinemia and hypopotassenemia, which disappeared after pull-through resection of the rectum.<BR>The commonest antecedant etiologic condition was costipation. Electro-myographic study was carried out to verify the dysfunction of the pelvic floor in cases of the rectall prolapse. The dysfunctioning pelvic floor is an important precipitating condition, if not a primary etiology, in developing and accelerating the prolapse.<BR>Of manifold therapeutic procedures, Roscoe-Grahams operation was most effective to, prevent recurrence. The Gant-Miwa plication method with Thiersch wire was proved to be a simple but effective procedure and worthy of trial.
