LSG vs OAGB-1 Year Follow-up Data-a Randomized Control Trial

Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedure. One anastomosis gastric bypass (OAGB) is rapidly emerging as a safe and effective metabolic procedure. This study aims at comparing the 1-year follow-up results of OAGB and LSG in terms of excess weight loss, complications, resolution of comorbidities, and quality of life.

A prospective randomized study of results between 100 LSG and 101 OAGB patients was done from 2012 to 2015. The results were compared regarding operative outcomes, percentage of excess weight loss, complications, resolution of comorbidities, and quality of life (BAROS score).

The mean BMI for the OAGB and LSG group was 44.31 and 43.75 kg/m², respectively. Percentage of excess weight loss (%EWL) for OAGB vs LSG was 66.87 ± 10.87 vs 63.97 ± 13.24 at 1 year (p > 0.05), respectively. Diabetes remission was 83.63 % in OAGB patients and 76.58 % in LSG patients. Remission of hypertension is 64.15 % in OAGB patients and 66.07 % in LSG patients. Bariatric Analysis Reporting and Outcome System (BAROS) was 3.71 in LSG and 3.96 in OAGB.

In our study, there was no significant difference between LSG and OAGB in outcome at 1 year follow-up in % excess weight loss, remission of HTN, and quality of life. OAGB has marginally better outcome in T2 DM remission. However, a longer follow-up is required to establish a correct comparative result.
