OAGB
Also written as: OAGB — One Anastomosis Gastric Bypass
One anastomosis gastric bypass, also known as mini gastric bypass, involving a single connection between stomach and small intestine.
Full Definition
OAGB (One Anastomosis Gastric Bypass) is a bariatric surgical procedure that creates a long, narrow gastric pouch connected to the small intestine via a single anastomosis. Unlike the traditional Roux-en-Y gastric bypass which requires two anastomoses, OAGB involves only one surgical connection, making it technically simpler and potentially faster to perform. The procedure provides both restrictive and malabsorptive weight loss mechanisms. OAGB has gained popularity due to its relative technical simplicity, though concerns about bile reflux and long-term complications continue to be studied in the literature.
Usage
Usage note: May be used interchangeably with MGB (mini gastric bypass) in some contexts.
