Abstract
BACKGROUND AND AIMS: Pouch sinus may be a serious adverse event in patients undergoing ileal pouch-anal anastomosis. The aim of this study was to compare endoscopic sinusotomy (ESi) and redo pouch surgery in the management of pouch sinus. METHODS: All consecutive ulcerative colitis patients with chronic pouch sinuses treated with ESi versus redo surgery from 2006 to 2016 were identified. The primary outcomes were recurrence-free and surgery-free survivals. The secondary outcome was postprocedural adverse events. RESULTS: This historical cohort study included 226 patients (ESi, n = 141; redo surgery, n = 85). Complete healing of the sinus was achieved in 75 patients (53.2%) and partial healing in 23 patients (16.3%) with ESi, and an initial complete healing (ie, no anastomotic leak before ileostomy closure) was obtained in 80 patients (94.1%) receiving redo surgery. Sinus recurrence after complete healing was seen in 17 patients (22.7%) treated with ESi and 28 patients (32.9%) treated with surgery (P = .15). Subsequent surgery was needed in 34 patients (24.1%) with ESi therapy and 18 patients (21.2%) with initial redo surgery (P = .70). Kaplan-Meier recurrence-free and surgery-free survivals after initial procedures showed no statistical difference between the 2 groups (P = .42 and P = .65, respectively). The rate of adverse events in the ESi group was significantly lower than that in the surgery group (2.5% vs 43.5%, P < .0001). CONCLUSIONS: Recurrence-free and surgery-free survivals were comparable between patients treated with ESi and redo surgery, whereas pouch redo surgery was found to be associated with a higher immediate complete healing rate yet a higher morbidity.
