Purpose Resizing of the gastric pouch, with eventually resizing of the gastrojejunal anastomosis, has been proposed as revisional procedure to treat weight regain after Roux-en-Y gastric bypass (RYGB), in patients with large gastric pouch and/or large gastrojejunal (GJ) anastomosis. The aim of this study is to determine the midterm results and the safety of laparoscopic resizing of the gastric pouch after RYGB in cases where gastric pouch is > 200 ml and/or GJ anastomosis > 20 mm.

Background: Laparoscopic sleeve gastrectomy (SG) became the most performed surgical intervention for treating population with morbid obesity. However, revisional surgery after SG has been increasingly performed due to weight loss failure. We describe the results of a single surgeon’s experience with conversion of SG to one anastomosis gastric bypass (OAGB) in patients with previous SG and weight loss failure. The aim of the study is to analyze the short- and mid-term results of conversion of SG to OAGB for failure of weight loss.
