Continent colonic conduit for rectal evacuation in severe constipation.

We describe a new operation for the treatment of rectal evacuatory disorders: a continent colonic conduit, incorporating an intussuscepted valve, was constructed from the sigmoid colon. Intubation of the conduit allowed irrigation and evacuation of the distal colon and rectum. Initially all 10 patients reported a reduction in time taken and the discomfort involved in completing evacuation. The number of stools passed per week increased in 9 out of 10 patients, from a median of 1.5 (range 0.25-7) to a median of 7 (range 3-7) postoperatively. Subsequently, 3 patients developed complications, 2 of whom required conversion to an ileostomy. Overall, the colonic conduit procedure was successful in treating the rectal evacuatory disorder in 7 patients, failed in 2, and 1 patient has a temporary defunctioning ileostomy. The procedure is a relatively simple surgical alternative for the treatment of a condition which is often resistant to conservative measures.
