[Change to continent colostomy with secondary sphincter transplant].

Intesive histological and biomechanical examinations have shown that the smooth muscles of the human gastrointestinal tract can be freely transplanted to take over the functions of a sphincter. In this study it has been shown how conventional colostomy can be converted into a continent one with the aid of a sphincter plasty. The operational technique, especially encircling the rectum, provides protection at the same time against prolapse of the anus praeternaturalis.
