BACKGROUND: Super obesity [body mass index (BMI) > 50 kg/m2] can yield to higher morbidity/mortality in bariatric surgery, this could be related to patient's characteristics and/or surgeon's experience. In morbid obesity, both techniques proved to have a positive impact and sometimes comparable outcomes during the first 2 years. This has not been clearly analyzed in the super obese patient. METHODS: Retrospective study comparing the records of 77 consecutive super obese patients (BMI: 50-59.9 kg/m2) submitted to either laparoscopic gastric bypass (LGBP, n = 32) or laparoscopic sleeve gastrectomy (LSG, n = 45) between 2010 and 2012 at a single institution. The primary objective was to analyze baseline demographics, comorbidities, operative outcomes, and early complications (<30 days). Secondarily, weight loss [BMI and % excess weight loss (%EWL)] was also described and compared during the first year. RESULTS: Female sex comprised 72.7 % of all cases. Both groups had comparable BMI (52.7 ± 2.1 kg/m2 for LGBP vs. 53.87 ± 2.8 kg/m2 for LSG; p = 0.087) and homogeneous baseline characteristics. Operative time was lower for the LSG group (113.1 ± 35.3 vs. 186.9 ± 39 min for LGBP; p ≤ 0.001). Overall, early complications were observed in 16.8% of patients (LGBP 9% vs. LSG 22%; p = 0.217). There were four major complications (two in each group), with two reinterventions. Weight loss (%EWL) at 6, 9, and 12 months was significantly higher in the LGBP group (51.6 ± 12.9%, 56.5 ± 13%, 63.9 ± 13.3%, respectively) than in the LSG group (40 ± 12.8%, 45.1 ± 15.5%, 43.9 ± 10.4%, respectively). CONCLUSIONS: Just like in morbid obesity, LGBP and LSG are effective and safe procedures in super obese patients. LGBP had better weight loss at 1 year.
