Duodenal-jejunal bypass for the treatment of type 2 diabetes in Chinese patients with an average body mass index<24 kg/m2

DJB can improve glycemic control in nonobese T2 DM patients without significant weight loss but may not be effective enough to induce remission of T2 DM in nonobese Chinese patients. A larger sample size and more constrictive inclusion criteria may be required for better evaluation.
