Standard vs distal Roux-en-Y gastric bypass in patients with body mass index 50 to 60. A double-blind, randomized clinical trial. JAMA Surg 2016; 151: 1146-1155.

Published: 1st March 2017

Authors: Risstad H, Svanevik M, Kristinsson JA, Hjelmesæth J, Aasheim T, Hofsø D et al.

Conclusion

This study included 113 patients followed for two years. Mean reduction in body mass index was similar after both procedures: between group difference 0.6, 95 per cent confidence interval -0.6 to 1.8, P=0.32. Number of adverse events, and health-related quality of life were also similar.
