AIM: To investigate the feasibility and long-term functional outcome of ileal pouch-anal anastomosis with modified double-stapled mucosectomy.
METHODS: From January 2002 to March 2011, fourty-five patients underwent ileal pouch anal anastomosis with modified double-stapled mucosectomy technique and the clinical data obtained for these patients were reviewed.
RESULTS: Patients with ulcerative colitis (n = 29) and familial adenomatous polyposis (n = 16) underwent ileal pouch-anal anastomosis with modified double-stapled mucosectomy. Twenty-eight patients underwent one-stage restorative proctocolectomy, ileal pouch anal anastomosis, protective ileostomy and the ileostomy was closed 4-12 mo postoperatively. Two-stage procedures were performed in seventeen urgent patients, proctectomy and ileal pouch anal anastomosis were completed after previous colectomy with ileostomy. Morbidity within the first 30 d of surgery occurred in 10 (22.2%) patients, all of them could be treated conservatively. During the median follow-up of 65 mo, mild to moderate anastomotic narrowing was occurred in 4 patients, one patient developed persistent anastomotic stricture and need surgical intervention. Thirty-five percent of patients developed at least 1 episode of pouchitis. There was no incontinence in our patients, the median functional Oresland score was 6, 3 and 2 after 1 year, 2.5 years and 5 years respectively. Nearly half patients (44.4%) reported “moderate functioning”, 37.7% reported “good functioning”, whereas in 17.7% of patients “poor functioning” was observed after 1 year. Five years later, 79.2% of patients with good function, 16.7% with moderate function, only 4.2% of patients with poor function.
CONCLUSION: The results of ileal pouch anal anastomosis with modified double-stapled mucosectomy technique are promising, with a low complication rate and good long-term functional results.
