Endoscopic revision of one-anastomosis gastric bypass (ER-OAGB) for weight recurrence: a case series of 17 adults.

Endoscopic revision of one-anastomosis gastric bypass for weight recurrence The one-anastomosis gastric bypass (OAGB) is now the third most commonly performed metabolic and bariatric surgery worldwide. As with other weight loss surgeries, the OAGB is associated with weight recurrence over time that prompts patients to seek further treatment; however, revisional surgeries are known to carry increased risk. The endoscopic revision of the OAGB (ER-OAGB) is an incisionless technique that reduces the gastrojejunal anastomosis and gastric pouch to facilitate weight loss after weight recurrence in OAGB. Here, we showed in a series of 17 adults that the ER-OAGB safely helped patients lose over 18% of their body weight within the year following their revision.
