摘要

Background The Roux-en-Y gastric bypass continues to be one of the most performed bariatric surgeries because of its adequate balance of outcomes, complications, and durability. Recently, the role of the biliopancreatic limb on weight loss and co-morbidity control has gained attention because it seems to have a positive impact based on limb length. Objective To compare results at 12 months of a "standard" (group 1) versus a long (group 2) biliopancreatic limb bypass. Biliopancreatic limbs were 50 cm and 200 cm, and alimentary limbs were 150 cm and 50 cm, respectively. Setting Academic Referal Center; Mexico City; Public Seeting. Methods Randomized study with patients undergoing both types of surgeries at a single academic center from 2016 to 2018. The analysis included weight loss, co-morbidity control (diabetes and hypertension), biochemical panel, operative outcomes, and complications. Results Two-hundred ten patients were included (105 in each group). Almost all data were homogenous at baseline. Female sex comprised 86.1% of cases, with a mean body mass index of 43.5 kg/m2. Excess weight loss (77.6 ± 15.7% versus 83.6 ± 16.7%; P = .011) and total weight loss (33.5 ± 6.4% versus 37.1 ± 7.1%; P < .001) was higher in group 2; better HbA1C levels were also observed. Co-morbidity outcomes, operative data, and complications were similar between groups. Conclusion The Roux-en-Y gastric bypass with 200 cm of biliopancreatic limb length induces more weight loss at 12 months than a 50 cm limb length. Better HbA1C levels were also observed, but similar effects on co-morbidities and complications were noted.
