Objectives: Analyze the evolution of body mass index (BMI) and percentage of excess weight loss (PEWL) after bariatric surgery; compare adjustable gastric banding (LABG) vs laparoscopic gastric bypass (LGB).

Methods: Cohort study. Inclusion criteria: all cases underwent laparoscopic bariatric surgery; n=89; 9 patients were excluded for incomplete follow up. Differences between the 2 groups were evaluated using the Student t-test; P<0.05 was considered significant.

Results: n=80 (35 LABG/45 LBG).
