Comparative study of midterm outcomes between Roux-en-Y gastric bypass (RYGB), diverted one-anastomosis gastric bypass (D-OAGB), and one anastomosis gastric bypass (OAGB)

D-OAGB demonstrated favorable outcomes, including lower early adverse events and superior weight loss results in the first 6 months post-surgery when compared to RYGB. The D-OAGB group also showed higher rates of GERD remission and lower de novo GERD occurrence than OAGB. Further research is warranted to validate these findings and expand our understanding of this innovative surgical approach.
