Clinical experience with total colectomy and endorectal mucosal resection for inflammatory bowel disease

During the past 3 yr, 17 patients with chronic ulcerative colitis and 6 with Crohn's disease who had severe rectal and colonic involvement underwent excision of the rectal mucosa without removal of the rectal muscle in combination with total colectomy and cutaneous ileostomy as a 1- or 2-stage procedure. This operative technique has cured each of the patients of their primary colonic and rectal disease and has obviated many of the unpleasant complications that often occur after total proctectomy, such as impotence, prolonged perineal drainage, and bladder dysfunction. The operation has the further advantages of lower operative blood loss, shorter operative time, and earlier safe ambulation. On the basis of the favorable experience with mucosal proctectomy, sphincterotomy, and perineal drainage in 23 patients, none of whom experienced major complications, we believe that this operation warrants further clinical trial in patients with inflammatory bowel disease involving the rectum, which is refractory to medical therapy. Total proctectomy might eventually find scant application in patients with inflammatory bowel disease.
