Bariatric surgery between encouragement and inhibition: Sohag experience of first 50 cases with encouraging results

Abstract

Background: The advantages of bariatric surgery are improved co-morbidity, quality of life and survival in obese patients. Nowadays, many studies compare effectiveness of different bariatric surgery procedures. Our aim is to evaluate effectiveness of two laparoscopic bariatric surgery procedures performed in our centre (SG and OAGB) as regard outcome and post- operative complications.Methods: A retrospective study for our first 50 cases of bariatric surgery. Primary outcome was weight loss expressed as kilograms, body mass index (BMI) reduction and percentage excess weight loss % EWL. Secondary outcomes were remission or control of associated diabetes mellitus type2, hypertension and dyslipidaemia.Results: LSG was done in 38 cases and OAGB in 12 cases. Mean operating time for LSG was 75.6±10.5 min and for OAGB was 98.5±11.5 min. Mean length of hospitalization for LSG was 3.7±1.4 days and for OAGB was 5.2±1.6 days. Post-operative complication occurred in one patient (2.6%) with LSG and in two patients (16.6%) with OAGB. No significant statistical differences were found as regard short term complications or death. Mean EWL at 6 months was higher in patients receiving OAGB (59%) compared to those receiving LSG (47%). After 1 year it was (73% vs. 62%) and at 1.5 years (87% vs. 76%), respectively. At 6 months, associated comorbidities showed significant improvement in both groups but more with OAGB.Conclusions: For the short term, OAGB appears to achieve better %EWL and remission of obesity-associated comorbidities compared with the LSG.
