Introduction: bariatric surgery has been used as an effective option for weight control and associated comorbidities.
Objective: to determine the usefulness of the Gastric Sleeve and Roux-en-Y Bypass in the control of overweight.
Methods: a search for information was carried out in the databases PubMed, Google Scholar, TripDatabase, Cochrane Central Register of Controlled Trials, using search formulas by combining MeSH terms.
Results: 1378 patients who underwent bariatric surgery were analyzed (48,6 % with sleeve gastrectomy and 51,4 % with Roux-en-Y gastric bypass. A weight reduction of 41,5 % was observed after sleeve gastrectomy and 47,8 % after Roux-en-Y gastric bypass. The mean BMI at 5 years was 33,7 kg/m² for sleeve gastrectomy and 32,5 kg/m² for gastric bypass. Comorbidities control was observed for both sleeve gastrectomy and Roux-en-Y gastric bypass for type 2 diabetes (64,10 % and 65,40 % respectively), hypertension (45,60 % and 58,50 % respectively) and dyslipidemia (55,30 % and 68,70 % respectively). As for late complications, they were observed in 8,5 % of sleeve gastrectomies and in 14,38 % of bypasses.
Conclusions: both operations were equally safe and effective in improving quality of life and control of comorbidities, with LSG having a higher incidence of de Novo Gastroesophageal Reflux. However, further studies are required to evaluate the deficiencies and complications associated with these procedures
