Principal investigator Tong Weidong, Professor
Description Currently, there is a growing evidence supports the efficacy of Roux-en-Y gastric bypass for the treatment of Type 2 diabetes mellitus. However,there still have a great controversy about the operation parameters. With randomized controlled trial, Patients of BMI>21kg/m2 with type 2 diabetes were randomly divided into two groups: short biliarypancreatic limb:50cm;long biliarypancreatic limb :100cm. The investigators followed-up 3,6,12,24 months of the change of BMI,FBG,HbA1c,Blood pressure,Blood fat after surgery.
