title: Impact of sleeve gastrectomy verses sleeve gastrectomy plus side-to-side jejunoileal anastomosis on weight loss and metabolic control in an obese rat model.
abstract: OBJECTIVE
  To study the impact of sleeve gastrectomy plus side-to-side jejunoileal anastomosis on weight loss and the remission of type 2 diabetes mellitus.
  
  
  METHODS
  Thirty-three 7 weeks old male Zucker diabetic fatty rats were randomized into three groups: sleeve gastrectomy plus side-to-side jejunoileal anastomosis (JI-SG group), sleeve gastrectomy (SG group), sham surgery (Control group).
  
  
  RESULTS
  The weight of rats in JI-SG group and SG group was significantly lower than control group at 2 weeks postoperatively, and body weight in JI-SG group was lower than SG group since 4 week postoperatively. The blood Glucose was significantly improved for both JI-SG group and SG group, and increased in Control group at 2 weeks after surgery. The serum ghrelin level of rats in JI-SG, SG group was significantly decreased, but without difference between two groups; compared with that preoperatively, the GLP-1 level of rats in JI-SG group was significantly higher at 12 weeks postoperatively; SG group and SO group had no difference in the GLP-1. The serum insulin level in rats was also decreased in JI-SG group and SG group at 6 weeks postoperatively, and plasma insulin level in JI-SG group was significantly lower than those in the SG group at 12 weeks postoperatively.
  
  
  CONCLUSIONS
  JI-SG is superior to SG as the treatment of type 2 diabetes mellitus and weight control in obese diabetic rodents.
