Over the last 40 years, the Roux-en-Y Gastric Bypass (RYGB) has been the gold standard in the surgical management of morbid obesity. and is a validated bariatric procedure in France. Nevertheless, the RYGB remains a technically demanding procedure; thus and in order to overcome the complexity of this intervention, a simpler technique based on a single anastomosis at 200cm from the Treitz angle creating an omega loop (Mini Gastric Bypass - MGB or One Anastomosis Gastric Bypass-OAGB) has gradually spread around the worl without prior evaluation, . In 2018, the MGB was officially recognized by the International Federation of Bariatric Surgery (IFSO) as a standard procedure but not by the ASMBS American Society for Metabolic and Bariatric Surgery ; indeed, the OAGB remains controversial because considered by many surgeons at risk of biliary reflux and malnutrition.
