AI simplified
Abstract
Patients undergoing one-anastomosis gastric bypass (OAGB) experienced a 5.89% greater total weight loss compared to those undergoing Roux-en-Y gastric bypass (RYGB) after revisional surgery.
- OAGB is associated with more significant total weight loss after revisional surgery compared to RYGB.
- The overall early complication rate is similar for both OAGB and RYGB procedures.
- Four retrospective comparative studies with a total of 499 individuals were analyzed.
- Data limitations and heterogeneity restrict the ability to draw definitive conclusions.
