Laparoscopic One Anastomosis Gastric Bypass (OAGB)
It is one of the more recently introduced gastric bypass procedures. One Anastomosis Gastric Bypass (OAGB), also known as mini-gastric bypass or single anastomosis gastric bypass, is a type of weight-loss surgery that combines elements of both restrictive and malabsorptive procedures. It differs from the conventional Roux-en-Y gastric bypass by the way of having a larger gastric pouch (about 200 ml) similar to the sleeve gastrectomy and a single loop connection between the small intestine (jejunum) and the pouch. It is more malabsorptive than restrictive.

OAGB may be suitable for patients with a high BMI (typically over 35) and weight-related health issues. It might also be an option for those who haven’t responded well to diet and exercise or have struggled with complications from other weight-loss surgeries.
OAGB offers significant weight loss and improvement in weight-related conditions like type 2 diabetes. It also involves only one connection (anastomosis) between the stomach pouch and intestine, potentially reducing surgical time and complication risks.
As with any surgery, OAGB carries some risks like infection, bleeding, and nutritional deficiencies. There’s also a possibility of bile reflux causing heartburn.
Following OAGB, you’ll need to follow a specific diet plan for healing and adjusting to the digestive changes.
