To analyze the current status regarding indications and long-term results of One-Anastomosis Gastric Bypass (OAGB), emphasizing its significance in bariatric surgery.
Key Findings:
OAGB is effective for long-term weight loss and metabolic improvement, with a significant reduction in HbA1c and higher remission rates for type 2 diabetes compared to RYGB and SG, particularly in terms of BMI reduction.
Long-term complications include bile reflux, malnutrition, vitamin deficiencies, and marginal ulcers, which should be closely monitored.
Some studies report higher rates of GERD and conversion to RYGB, while others indicate a low rate of revisional surgery after OAGB, suggesting variability in outcomes.
Interpretation:
OAGB is a recognized and effective bariatric procedure with notable benefits for weight loss and metabolic health, though it carries risks of specific long-term complications that require careful management.
Limitations:
The review only included studies published in English, potentially limiting the scope of findings and introducing bias.
Exclusion of studies with less than 60 months follow-up may omit relevant short-term data that could inform patient selection.
Conclusion:
OAGB is a viable option for severe obesity treatment, demonstrating effective long-term outcomes, but careful patient selection and ongoing monitoring for complications are essential.
