Therapeutic effects of laparoscopic Roux-en-Y gastric bypass on T2DM patients with different BMI / 中华内分泌外科杂志

ABSTRACT

Objective To investigate the clinical efficacy of laparoscopic Roux-en-Y gastric bypass on type 2 diabetes mellitus(T2DM) with different body mass index (BMI).Methods 62 T2DM patients were collected and divided into low BMI,medium BMI,and high BMI groups respectively according to BMI 25-28(kg/m2),28-33(kg/m2),≥33(kg/m2).All patients received laparoscopic Roux-en-Y gastric bypass and the clinical curative effects were monitored and analyzed subsequently.Results At 12 months postoperatively,the levels of total cholesterol(TC),triglyceride(TG) and BMI in medium and high BMI group were lower compared with those before surgery (P＜0.05).In low,medium BMI,and high BMI groups,the therapeutic effective rate was 81.8％(9/11),97.4％ (38/39),and 100％(12/12) respectively.The levels of fasting C-peptide and postprandial 1 h C-peptide were higher compared with those before surgery (P＜0.05).Conclusion Laparoscopic Roux-en-Y gastric bypass has good clinical curative effect for T2DM with different BMI,but for low BMI patients,the selection should be more cautious.
