    One anastomosis gastric bypass (OAGB) is a simpler surgical technique compared to Roux-en-Y gastric bypass, requiring only a single anastomosis.

  • 2

    Revision rates for OAGB range from 2% to 5%, with common causes for revision including inadequate weight loss and severe bile reflux.

  • 3

    Various revision techniques for OAGB include biliary-pancreatic limb lengthening, pouch re-sizing, and conversion to Roux-en-Y gastric bypass.

  • 4

    All surgeries were performed laparoscopically, with a standardized approach to OAGB involving specific measurements for the gastric pouch and anastomosis.

  • 5

    Postoperative follow-up included evaluations at multiple intervals, focusing on complications, revisional success, and percentage of excess weight loss.
