Omega Gastric Bypass (150cm) Compared to the Roux-en-Y Gastric Bypass (YOMEGA-2 Multicentric Trial)

Obesity with its consequences such as type 2 diabetes, high blood pressure, dyslipidemia, fatty liver disease, sleep apnea and cancers, remains a major healthcare problem worldwide. Bariatric surgery, combined with nutritional education and close monitoring, has been shown to be the most effective treatment for patients with morbid obesity resulting in significant and lasting weight loss and improvements in co-morbidities . With nearly 50000 procedures per year France ranks third in the world in terms of care for patients suffering from morbid (BMI ≥ 40 kg/m²) and severe (BMI 35-40 kg/m²) obesity. In parallel with the significant increase in the number of patients operated on for obesity in the world, over the past two decades, significant development has been observed in the field of bariatric surgery with a decrease or even disappearance of some procedures and the appearance of others. Performed for more than 40 years, the Roux-en-Y Gastric Bypass (RYGB) is a restrictive and malabsorptive procedure and currently is considered as gold standard procedure for the treatment of morbid obesity and its comorbidities. However, despite the good effectiveness (with an average Excess Weight Loss % (EWL%) of approximatively 70% at 2 years), RYGB is technically demanding procedure with learning curve requiring more than 100 cases and an overall complication rate ranging from 10% to 20% Introduced in 2001, one anastomosis gastric bypass (OAGB) is a modified gastric bypass that consists…
