Poor outcome of a defunctioning stoma after pouch construction for ulcerative colitis

Background: Restorative proctocolectomy for ulcerative colitis can have complications necessitating a later defunctioning ileostomy with uncertain outcome. This analysis was undertaken to assess the outcome in patients needing a later defunctioning ileostomy after pouch construction in patients with ulcerative colitis. Method: The notes of our series of 154 patients who underwent restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis were reviewed and 28 patients identified who needed a later defunctioning ileostomy to deal with complications. Results: A later defunctioning ileostomy was necessary in 28 patients to deal with the following complications: sepsis in 11 patients (5 pouches failed), fistulas in 7 (5 pouches failed), poor function including ileoanal stenosis in 5 tall 5 failed), postoperative intraabdominal bleeding in 2 (both saved), pouchitis in 2 (1 excised) and small bowel obstruction in 1 (saved), 16 pouches were eventually excised or permanently defunctioned (59%). Conclusion: Complications necessitating a later defunctioning stoma after pouch construction carry a poor prognosis, especially when used for ileoanal stenosis and fistulae, Copyright (C) 2000 S.
