简要总结
Type 2 diabetes mellitus (T2DM) resolution in morbidly obese patients following bariatric surgery suggests the efficacy of metabolic surgery in non-morbidly obese patients (body mass index [BMI]<35 kg/m2). Many researches have shown available evidence about the efficacy and safety of metabolic surgery for resolution of T2DM in the non-morbidly obese. One of the most effective metabolic surgeries is laparoscopic Roux-en-Y gastric bypass (LRYGB). The investigators intend to run a 3 year prospective multicenter study to evaluate the remission efficacy of laparoscopic Roux-en-Y gastric bypass in Type 2 Diabetes mellitus with low BMI (BMI:25-35) in Asia area.
详细描述
The study is designed including 9 bariatric centers across Asia region( China, Korea, Phillipine, Singapore and Taiwan). Totally 500 patients with confirmed diagnosis of T2DM and BMI between 25-35 kg/m2 will be enrolled from January 2011 to December 2013. Preoperative surgical parameters, blood, biochemistry data, gastrointestinal hormones, upper gastrointestinal studies, abdominal ultrasound, peri-operative & postoperative complications will all be recorded and analyzed. Patient inclusion criteria: 1.) T2DM diagnosed over 1 year; 2.) age ranged 30-60 years; 3.) BMI 25-35 kg/m2; 4.) Patient consent and will to receive long-term follow up and periodic check up. Exclusion criteria: 1.) T1DM; 2.) Substance abuse; 3.) Planned pregnancy within 2 year after surgery; 3.) Uncontrolled psychiatric disease; 4.) Lost follow up. Institutions inclusion criteria: Professional experience over 30 LRYGB performed. Trial termination criteria: Surgical mortality over 0.5% in the first year, and Diabetes remission rate failure over 20% in one year.
All data will be collected yearly in one center. The analysis of parameter, statistics and brief results will be informed to enrolled institutions periodically.

结局指标
主要结局
Gastric Bypass in the Treatment of Type 2 Diabetes in Patients with a BMI of 25 to 35 kg/m2
时间窗: 3 years (from 2011 to 2013)
An observational, prospective and multi-center study will be carry out with IRB approval. A total of 500 type 2 diabetes mellitus patients with low BMI (25-35 kg/m2) will be collected in different surgical institutions. Pre and post operative biochemical parameters will be collected at the 1st, 6th, 12th, 24th and 36th months. Comparative outcomes will support the relationship between diabetes improvement or remission and the surgical intervention. Blood parameters: CBC, hs-CRP, SMA12, HbA1c, Fasting C-peptide, Insulin, OGTT,C-peptide and DM antibodies
