Abstract
BACKGROUND: Gastro-bronchial and gastro-colic fistulas (GB-GC) represent a rare, but serious complication after laparoscopic sleeve gastrectomy (LSG). The aim of this study is to evaluate the efficacy of endoscopic first-line approach with endoscopic internal drainage (EID) by inserting double pigtail stents (DPS) METHODS: We retrospectively analyzed data from 40 consecutive patients referred at two tertiary centers for gastro-bronchial (N=30) and gastrocolic (N=10) fistulas following LSG. Nineteen patients previously experienced emergency surgical drainage. The mean interval between the index surgery and endoscopic fistula treatment was 265.6±521 days. RESULTS: Healing of the fistulous tract was achieved in 19 patients (47.5%), with complete resolution at an average follow-up of 16 months. Mean time of treatment duration was 157.8±141 days with 5.0±2.9 endoscopic sessions. No major adverse events were registered. CONCLUSIONS: Despite complete fistula healing was achieved in less than 50% of our population, EID for GB/GC fistula after LSG still represents the most conservative approach with low complications rate. Previous surgical drainage seems to be a positive prognostic factor for endoscopic healing. While the longer the interval between the index surgery and endoscopic treatment, the lower was the rate of treatment success.
