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

Abstract Background It is frequently reported that bariatric surgery often leads to resolution of type 2 diabetes mellitus (T2 DM). Limited experience with duodenal-jejunal bypass (DJB) for the treatment of T2 DM has shown controversial results. We present the first study of DJB for T2 DM patients in China.
