Background and Aims: Although laparoscopic one anastomosis gastric bypass (LOAGB) is a promising bariatric procedure, a large number of surgeons have strong objections mainly because of risk of bile reflux, marginal ulceration, malnutrition, and long-term risk of gastric and esophageal cancer. Lateral enteroenterostomy placed distally to a gastrojejunal anastomosis shows efficacy in preventing bile reflux after gastric resection and gastrojejunal anastomosis, but at present its efficacy in a bariatric surgery context has not been evaluated. Patients and Methods: From January 2013 to December 2018, 100 patients have been admitted to our department to be treated by performing LOAGB. Patients have been divided into two groups on the basis of the indications to this surgical procedure; Group A: presence of de novo gastroesophageal reflux disease (GERD) or severe esophagitis after laparoscopic sleeve gastrectomy, with or without weight regain; Group B: LOAGB as primary procedure. Another group of 30 patients (Group C) underwent LOAGB with Braun anastomosis as primary bariatric surgical procedure for morbid obesity. We have conducted a retrospective analysis of the surgical outcomes in terms of perioperative mortality, short-, mid-, and long-term postoperative complications and weight loss. Results: Group A: 50 patients; incidence of postoperative GERD, esophagitis, or esophageal ulcers was 26% (13 cases). All these patients have been successfully treated by performing Braun anastomosis. Group B: 20 patients; incidence of de novo reflux was 25% (5 cases); Braun anastomosis was performed with complete resolution of signs and symptoms in all cases. Group C: 30 patients; no cases of de novo reflux, esophagitis, or anastomotic ulcers occurred. Conclusion: Braun anastomosis seems to be a useful surgical tool to prevent the onset of de novo reflux, esophagitis, and anastomotic ulcers.
