    One-anastomosis gastric bypass (OAGB) is increasingly recognized for its effectiveness in treating obesity and related medical conditions.

  • 2

    Concerns about postoperative reflux after OAGB persist, with studies reporting reflux in up to 70% of patients.

  • 3

    Upper endoscopy (UE) and biopsy are commonly used to diagnose reflux-related abnormalities post-OAGB, but their diagnostic accuracy remains unclear.

  • 4

    This study aims to compare the diagnostic precision of UE versus biopsy at one and three years after OAGB.

  • 5

    The research addresses significant knowledge gaps regarding the evolution of reflux-related findings and diagnostic methods after OAGB.
