Summary

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.

Conditions

Interventions

PROCEDURE

Laparoscopic Mini-gastric bypass

The laparoscopic Omega Loop Bypass performed 5 years ago consisted of a long gastric tube, stapled approximately 1.5 cm from the left of the lesser curvature of the antrum to the angle of His, a narrow gastric tube calibrated to be approximately 1.5 cm wide, an Omega loop of 200 cm, a unique gastro-jejunal anatomosis of 200cm from the ligament of Treitz, using a linear stapler

PROCEDURE

Laparoscopic Roux-en-Y Gastric ByPass (RYGBP)

The laparoscopic Roux-en-Y Gastric Bypass performed 5 years ago consisted of : a small gastric pouch (about 30cc), an antecolic alimentary limb, a gastro-jejunal anastomosis using a linear stapler, a 150cm long alimentary limb, a 50cm biliary limb, a latero-lateral jejuno-jejunal anastomosis, closure of the mesenteric defects.
