AimThe objective of this study is to compare 3-year follow-up results of one anastomosis gastric bypass (MGB-OAGB) and laparoscopic sleeve gastrectomy (LSG) in terms of weight loss, complications, resolution of comorbidities and quality of life.Materials And MethodsA prospective randomised study of results between 100 LSG patients and 101 MGB-OAGB patients was done from 2012 to 2015. The results were compared regarding operative outcomes, percentage of excess weight loss (%EWL), complications, resolution of comorbidities and quality of life (BAROS score) at 3 years follow-up.ResultsFollow-up was achieved in 93 MGB-OAGB vs 92 LSG patients for 3-year period. The average %EWL for MGB-OAGB vs LSG was 66.48 vs 61.15% at the end of 3 years respectively, which was statistically insignificant. Diabetes remission was seen in 89.13% of MGB-OAGB patients and 81.82% of LSG patients. Remission of hypertension was seen in 74% of MGB-OAGB patients and 72.22% of LSG patients. Bariatric analysis reporting and outcome system (BAROS) with comorbidity in LSG patients and MGB-OAGB patients was 6.03 and 6.96 respectively, whereas in patients without comorbidity, BAROS score was 3.86 in LSG group and 4.34 in MGB-OAGB group.ConclusionsIn our study, at 36 months follow up, there was no significant difference between LSG and MGB-OAGB in %EWL and remission of HTN. Type 2 diabetes mellitus (T2DM) remission rates were higher after MGB-OAGB as compared to LSG but the difference was statistically insignificant. MGB-OAGB patients with comorbidities have a better quality of life and BAROS score compared to LSG patients.
