RESUMO
OBJECTIVES: Restorative proctocolectomy and ileal pouch anal anastomosis (IPAA), with diverting ileostomy, are established ulcerative colitis (UC) treatments. The routine use of diverting ileostomy is controversial because of the risk of stoma closure and stoma related complications. In our institution, proctocolectomy and IPAA, with mucosectomy and handsewn anastomosis without diversion (one-stage IPAA), were performed for select patients with UC. The present study aimed to evaluate the clinical and functional outcomes of patients undergoing one-stage IPAA. METHODS: Between April 1999 and July 2017, 300 patients underwent one-stage IPAA in our institution. The clinical notes and prognosis were reviewed retrospectively. RESULTS: Postoperative complications (Clavien-Dindo classification grade ≥III) occurred in 18 patients (6.0%). The most common complication was anastomotic leakage (n = 9, 3%). There were 15 patients (5.0%) who required a defunctioning ileostomy. However, 13 patients successfully underwent ileostomy closure and achieved acceptable pouch function. Finally, two patients (0.6%) required pouch excision in this series. The cumulative pouch functional rate was 99.6% / 5 years and 99.2% / 10 years. CONCLUSIONS: One-stage IPAA is a good strategy for carefully selected patients with UC.
