One-anastomosis gastric bypass (OAGB) is recognized as a metabolic bariatric surgery (MBS) by the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) and the American Society for Metabolic and Bariatric Surgery (ASMBS). It is noted for high weight loss (WL) rates and resolving medical issues.
Studies indicate that OAGB provides superior WL results, fewer complications, and quicker procedures than Roux en Y gastric bypass (RYGB).
