Abstract (EN):
BackgroundSuper obesity (BMI 50kg/m(2)) is associated with significant morbidity and mortality. The best procedure to treat super obesity is not completely established. Our aim was to compare the effectiveness of bariatric procedures (adjustable gastric band [AGB], Roux-en-Y gastric bypass [RYGB], sleeve gastrectomy [SG]) in super obesity.MethodsRetrospective observational study of super obese patients who underwent bariatric surgery. Data was assessed preoperatively and in the 1st and 2nd years of follow-up.ResultsWe evaluated 213 individuals, 77.9% female, age of 43.3811.49years, and preoperative BMI of 54.53 +/- 4.54kg/m(2); 19 submitted to AGB, 127 to RYGB, and 67 to SG. In the pre-surgical assessment, there were no significant differences in age, anthropometric parameters, blood pressure, glycemic profile, and lipid profile between the three surgical groups. The percentage of excess weight loss (%EWL) in the 1st year was 67.58% in RYGB, 58.74% in SG, and 38.71% in AGB (p<0.001), and the percentage of total weight loss (%TWL) was 36.29%, 31.59%, and 21.07%, respectively (p<0.001). Two years after surgery (n=147; follow-up rate of 69%), the %EWL and %TWL were significantly higher in the RYGB group (p<0.001). RYGB had a higher success rate (%EWL 50% and %TWL 20%) in both years of follow-up (p<0.001). In multiple linear regression, after adjusting for other covariates, RYGB was the only strong predictive factor of %EWL and %TWL (p<0.001).Conclusion RYGB proved to be more effective in super obesity. The beneficial effects in weight loss were evident both 1 and 2years after the procedure, regardless of pre-surgical anthropometric characteristics.
