Ten years experience of one-stage restorative proctocolectomy for ulcerative colitis

Background Ileal-pouch anal anastomosis has an established role in the treatment of ulcerative colitis. Controversy exists regarding the routine use of a diverting ileostomy. The aim of this study was to review the clinical and functional outcome of patients undergoing restorative proctocolectomy in the absence of a diverting ileostomy (one-stage). Materials and methods Between 1990 and 1999, 87 patients with ulcerative colitis underwent a one-stage restorative proctocolectomy. The median age at the time of operation was 34 years (range 12–64 years) and median follow-up was 36 months (range 24–144 months). The clinical notes were reviewed retrospectively. Results The median in-patient stay was 15 days (range 9–36). There were no post-operative deaths. The complication rate within 30 days of surgery approximated to 40%. The median daytime pouch evacuation rate was 5. Only 13% of patients had to empty their pouch at night on a regular basis. Pelvic sepsis secondary to anastomotic leakage was the most commonly encountered problem, occurring in 15 patients. Small bowel obstruction was encountered in ten patients. One pouch required excision for a recurrent pouch-vaginal fistula. Conclusion Despite refinements in the surgical technique, restorative proctocolectomy is associated with significant morbidity. For a selected group of patients undergoing an ileo-anal anastomosis, a defunctioning ileostomy may be avoided.
