Prospective study including patients submitted to RYGB (n=94) and L-RYGB (n=94) at a single institution. The aim was to compare the effect on comorbidities and weight loss of a long biliopancreatic limb Roux-en-Y gastric bypass (L-RYGB), compared with a standard RYGB. Procedure selection was randomly assigned (1:1), and surgeries were performed, during 24 months (2016-2017). Weight loss, comorbidities control and nutritional status were assessed at baseline and 12 months.
