Roux-en-Y Gastric Bypass for the Treatment of Leak Following Sleeve Gastrectomy

Purpose Laparoscopic sleeve gastrectomy (LSG) is estimated to be its most severe complication. An aggressive management with surgical reconstructive procedures can be proposed in patients in whom all the conservative endoscopic techniques fail. The purpose of the present study was to report our experience with Roux-en-Y gastric bypass (RYGBP) as treatment for the chronic leak after LSG. Methods Between January 2013 and July 2019, 17 consecutive patients underwent RYGBP for the treatment of chronic leak after LSG. The initial intervention, the endoscopic approach and the definitive surgical repair were carefully reviewed. Results Seventeen patients (13 women) with a median age of 39 years (24–67) with a median body mass index (BMI) of 40 kg/m 2 (30–52) underwent RYGBP for persistent fistula. Sixteen patients had their early LSG performed in another hospital. Eleven patients had an initial endoscopic treatment by pigtail drains following laparoscopic drainage and 6 other patients had the endoscopic stent as the first-choice line treatment. The overall average fistula diagnosis was done at 7.7 months (2–49 months) for 12 patients. For the rest of five patients, the procedure was performed almost in the acute setting (
