Clinical Overview
Mini Gastric Bypass is a powerful bariatric procedure that combines restriction and malabsorption to provide excellent weight loss and resolution of metabolic diseases like diabetes.
Mini Gastric Bypass (MGB) / One Anastomosis Gastric Bypass (OAGB) is a modern, simplified alternative to traditional gastric bypass. It creates a long narrow stomach tube and connects it directly to a loop of the small intestine (single anastomosis). It is faster to perform, carries a low complication rate, and offers exceptional long-term weight loss and metabolic results.
