[Surgical creation of a reservoir-colostomy with reflex evacuation].
The authors consider that the problem of social rehabilitation of "colostomized" patients consists in an involuntary and sudden character of evacuation from the ostomy due to the absence of normal imperative urge to defecation. For this purpose a method of reservoir-retaining colostomy modulating the appearance of urge to defecation was worked out in experiments and used in clinic in 17 patients. Preconditions for the appearance of the urge were regular sensations due to mediated distention of the parietal peritoneum after filling the reservoir-retaining volume. The subjective sensations preceding the evacuation from the colostomy appeared 10-20 minutes before defecation and were felt as discomfort and abdominal cramping towards of the external end of the colostomy in 15 (88.2%) and as elements of intestinal colic in 2 (11.8%) patients. So, 9 (53%) patients managed to sufficiently control the evacuation from the ostomy and not to use the pouch. Five patients (29.4%) demonstrated the ability to restrain defecation for 10-15 minutes by straining the anterior abdominal wall muscles when the urge appeared. Evacuation from the ostomy was reiterative (2-4 times), once or twice a day, rarely 3-4 times a day and lasted from 15 till 60 minutes.
