Abstract: Background: Although Roux-en-Y gastric bypass (RYGB) results in significant weight loss and cardiometabolic risk factors improvements; there is no consensus whether limb lengths may influence these results. Objective: To evaluate the correlations between the common limb length (CLL) and hypertension remission rate, cardiometabolic risk factors, and nutritional parameters after RYGB. Settings: Private Hospital, Brazil. Methods: GATEWAY is a randomized trial designed to evaluate the efficacy of RYGB on hypertension improvement and other cardiometabolic risk factors in patients with grade I and II obesity compared with medical therapy. The follow-up was 1 year. We measured the entire bowel in all patients and used a 150-cm alimentary limb and a 100-cm biliopancreatic limb. Univariate logistic regression was used to estimate the relationship between CLL and hypertension remission. Pearson and Spearman correlation were used to evaluate the correlation between the CLL and the percentage changes of cardiometabolic risk factors and nutritional parameters. Results: From 100 randomized patients, 45 were submitted to RYGB and completed the follow-up. Mean CLL was 466.3 +/- 86.4 cm. Of patients, 55.6% from the RYGB group showed remission of hypertension. CLL length was not significantly associated with hypertension remission (odds ratio [95% confidence interval] for 50 units increase in CLL:.97 [.68; 1.38], P=.88). Consistently, we found no correlations between CLL and all changes in cardiometabolic risk factors and nutritional parameters. Conclusions: In a proximal RYGB, CLL does not influence hypertension remission, cardiometabolic risk factors, and nutritional parameters.
