Objective:

To compare mid-term outcomes of RYGB and OAGB versus D-OAGB in patients undergoing bariatric surgery, focusing on weight loss and complication rates.

Key Findings:

• D-OAGB may reduce bile reflux compared to OAGB, with a statistically significant reduction in adverse events.
• RYGB shows significant metabolic effects and remission of obesity-related conditions, with a higher percentage of patients achieving remission compared to OAGB.
• OAGB has gained popularity due to its simplicity and effectiveness, with a notable increase in its adoption rate in recent years.

Interpretation:

The study suggests that D-OAGB could be a viable alternative to OAGB and RYGB, potentially offering similar weight loss outcomes with reduced complications related to bile reflux, which may influence surgical decision-making.

Limitations:

• Retrospective design may introduce selection bias.
• Inclusion of patients with incomplete follow-up data could affect outcomes.
• Sample size may limit the generalizability of findings.

Conclusion:

D-OAGB presents a promising option for bariatric surgery, potentially combining the benefits of RYGB and OAGB while minimizing complications associated with bile reflux, as evidenced by the favorable outcomes observed in this study.
