Outcomes in Super Obese Patients Undergoing One Anastomosis Gastric Bypass or Laparoscopic Sleeve Gastrectomy

The data on the role of OAGB in super obese patients and its direct comparison with LSG in super obese patients is scarce.

To compare weight loss, impact on comorbidities and nutritional parameters between LSG and OAGB in super obese patients.

Prospectively collected data of 75 matched patients with BMI > 50, who underwent either laparoscopic sleeve gastrectomy (LSG) or one anastomosis gastric bypass (OAGB), was analyzed retrospectively. Percentage excess weight loss at 1 year and impact on comorbidities were compared in both the groups.

Both the groups were comparable for age, sex, BMI, and presence or absence of diabetes mellitus. Mean TWL% ± 2SD at 1 year was 30.09% ± 19.76 in patients undergoing LSG, while it was 39.9% ± 12.78 in patients undergoing OAGB (p < 0.001). In the LSG group, 85.7% and 66.67% of patients had remission of diabetes mellitus and hypertension, respectively, as compared to 77.77% and 78.5%, respectively, in the OAGB group. All the patients with OSA had a resolution of their symptoms in both the groups. Patients in the OAGB group became more folate deficient despite regular supplementation.

Weight loss following OAGB was found to be better than LSG in the super obese patients in our study. There was a similar resolution of comorbidities and a lesser rate of major complications in the OAGB group.
