RESUMO
INTRODUCTION: Reconstructive ileal-pouch anal anastomosis (IPAA) for ulcerative colitis (UC) is often created in 3-stages: colectomy â+ âileostomy, proctectomy â+ âpouch creation with diverting loop ileostomy, then subsequent ileostomy closure. Modified 2-stage IPAA is without pouch diversion, thus avoiding a third operation. This study compares perioperative complications, quality of life (QOL) and functional outcomes of 3- versus modified 2-stage IPAA. METHODS: Charts were reviewed for adult UC patients undergoing IPAA between 2010 and 2020. QOL and function were assessed with EQ-5D-3L Quality of Life and Pouch Functional Score questionnaires. RESULTS: 152 patients were identified. 43 modified 2-stage and 109 3-stage IPAA were similar for anastomotic leak (9.3% vs. 1.8%, p â= â0.06), SSI (34.9% vs. 29.7%, p â= â0.51) and ileus (32.6% vs. 33%, p â= â0.96). Modified 2-stage had less bowel obstruction than 3-stage IPAA (7.0% vs. 30.1%, p â= â0.006). 92 patients returned questionnaires with similar QOL and pouch function. CONCLUSIONS: Perioperative complications, QOL and function are similar for 3-stage IPAA and modified 2-stage IPAA. Modified 2-stage IPAA in select patients is safe and has less postoperative bowel obstruction than 3-stage IPAA.
