Impact of Biliopancreatic limb length (70 cm vs 120cm), with constant 150cm Alimentary limb, on long-term weight loss, remission of comorbidities and supplementation needs after Roux-en-Y gastric bypass
Abstract
.
Background The best alimentary and biliopancreatic limb (BPL) lengths in the Roux-en-Y gastric bypass (RYGB) still remain unclear. The aim of this study was to compare the effect of a BPL of 70 vs 120 cm, with a constant AL of 150 cm on long-term weight loss, remission of comorbidities, and supplementation needs after RYGB. Patients and Methods A prospective randomized study of morbidly obese patients undergoing RYGB was performed. Patients were randomized into two groups: those patients undergoing RYGB with a BPL of 70 cm (BPL 70 cm) and those ones undergoing RYGB with a BPL of 120 cm (BPL 120 cm). BMI, excess BMI loss (EBMIL), remission of comorbidities and specific vitamin and mineral supplementation needs at 1, 2, and 5 years were analyzed. Results Two hundred fifty-three patients were included in each group. There were no significant differences in BMI, EBMIL and the remission of diabetes mellitus, hypertension, and dyslipidemia between groups at 1, 2, and 5 years after surgery. Patients from group BPL 120 cm required greater specific supplementation of vitamin B12, folic acid, and vitamin A during all the follow-up. Conclusion A RYGB with 120 cm BPL does not achieve greater weight loss or remission of comorbidities than a RYGB with 70 cm BPL but is associated with greater deficiencies of vitamin B12, vitamin A, and folic acid.
