Role of Endoscopic Internal Drainage in Treating Gastro-Bronchial and Gastro-Colic Fistula After Sleeve Gastrectomy.

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.
