[Ileorectostomy versus ileo-anal anastomosis with reservoir in ulcerative colitis and colonic adenomatosis].

In the last ten years, approximately 200 mucosal proctectomies have been performed as an alternative to proctocolectomy, but also as an alternative to ileorectostomy in cases of UC and AC. Operative mortality is minimal but the rate of early postoperative complications is considerable (greater than 10%). After an adaptive phase, however, functional results are generally good. The substantial risks of ileorectostomy in AC (degeneration rate up to 20%) and in UC (inflammation relapse 20-30%, secondary degeneration approximately 5%) have led to the establishment of mucosal proctectomy as the treatment of choice in the larger surgical centres.
