Endoscopic treatment of fistula after sleeve gastrectomy: results of a multicenter retrospective study.

Background And Study Aims: Fistula is the main complication of laparoscopic sleeve gastrectomy (LSG), for which healing is difficult to achieve. The aims of the study were to evaluate the efficacy of interventional endoscopy for post-LSG fistula treatment, to evaluate various endoscopic techniques used and identify their complications, and to identify predictive factors of healing following endoscopic treatment.

Patients And Methods: This retrospective multicenter study included patients with post-LSG fistula.
