BACKGROUND: Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis.

OBJECTIVES: To evaluate the long-term functional outcome of patients who underwent this surgical procedure.

METHODS: We performed this observational study in 174 consecutive patients: 146 with UC and 28 with FAP. The patients, 91 males and 83 females with a mean age of 34.1+/-10.6 years (range 6-67 years), underwent the procedure between January 1984 and January 2004 (mean follow-up 64.8 months, range 1-240 months). The indications for surgery were intractable disease in 124 patients (71%), dysplasia in 36 (21%), severe bleeding in 8 (5%), and perforation in 6 (3%).

RESULTS: A protective ileostomy was performed in 140 patients (96%) with UC and 12 (43%) with FAP. An urgent three-stage procedure was necessary in 14 patients (8.4%). A mucosal proctectomy was performed in 94 (54%), and a double stapling technique in 80 (46%). Mean length of hospital stay was 9.4+/-6.6 days (range 5-34 days, median 8). Complications included pelvic sepsis in 7 patients (4.2%), anastomotic leakage in 8 (4.8%), bowel obstruction in 22 (13.2%), incisional hernia in 12 (7.2%), anastomotic stenosis that usually responded to manual dilatation in 46 (27.6%), pouchitis in 106 (61%), recto-vaginal fistula in 3 (1.8%), retrograde ejaculation in 3 (1.8%), and impotence in 2 (1.2%). There was no mortality in this group of patients. The median number of bowel movements per 24 hours was six in UC patients and five in FAP patients, with at least one bowel movement during the night. Complete daytime and night-time continence was documented in 124 patients (71%). Overall satisfaction was 95%.

CONCLUSIONS: Restorative proctocolectomy with ileal pouch-anal anastomosis confers a long-term good quality of life to both UC and FAP patients, and the majority of patients are fully continent with five to six bowel movements per day.
