mini gastric bypass
Also written as: MGB — mini gastric bypass
A simplified gastric bypass procedure creating one anastomosis between stomach pouch and small intestine.
Full Definition
Mini gastric bypass, also known as one-anastomosis gastric bypass, is a bariatric procedure that creates a small gastric pouch and connects it directly to the small intestine with a single connection point. This technique is simpler than traditional Roux-en-Y gastric bypass as it requires only one anastomosis rather than two. The procedure combines restriction and mild malabsorption to achieve weight loss while potentially reducing operative time and complexity.
Usage
Usage note: Also abbreviated as OAGB (one-anastomosis gastric bypass).
