Abstract

Background

This study aims to evaluate and compare long-term results of laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) based on bariatric analysis reporting and outcome system (BAROS) score.

Materials and Methods

Patients operated for morbid obesity between 2013 and 2015 were randomised to LSG and OAGB groups. Based on inclusion and exclusion criteria, 201 patients (100 LSG and 101 OAGB) were analysed for changes in total body weight (TBW), body mass index (BMI), percent excess weight loss (%EWL), percent total weight loss (%TWL), QoL (quality of life) scores, comorbidity resolution and outcome based on BAROS at 7 years.

Results

Sixty-six LSG and 64 OAGB patients were followed up at 7 years. Mean pre-operative TBW and BMI were 119 ± 28.2 and 44.87 ± 7.71 for LSG group and 113.25 ± 23.74 and 44.71 ± 8.75 for OAGB group respectively. At 7 years after surgery, there was significant drop in mean TBW and BMI in both groups. Mean %EWL for LSG and OAGB patients was 50.78 ± 28.48 and 59.99 ± 23.32 and mean %TWL for LSG and OAGB patients was 23.22 ± 12.66 and 27.71 ± 12.27 respectively. Mean QoL scores at 7 years were significantly higher than the pre-operative scores and most of the patients in both groups had remission or improvement in their comorbidities. 68.76% OAGB patients had very good or excellent outcome on BAROS score while only 36.37% LSG patients had similar outcome.

Conclusions

LSG and OAGB are successful bariatric procedures over the long term. OAGB outperforms LSG and has significantly higher %EWL and %TWL over the long term.
