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

Obesity Surgery 2019 January 19
INTRODUCTION: The data on the role of OAGB in super obese patients and its direct comparison with LSG in super obese patients is scarce.

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

METHODS: 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.

RESULTS: 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.

CONCLUSION: 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.
