BACKGROUND: Nowadays, more than 170 million patients suffer from diabetes mellitus worldwide. This study aimed to investigate the effects of sleeve gastrectomy (SG) and ileal transposition (IT) surgery on the control of diabetes.

MATERIAL AND METHODS: Goto-Kakizaki rats were used to establish type 2 diabetes models and undergo SG or IT surgery. At 2 months post-surgery, insulin, glucose, triglycerides (TG), total cholesterol (TC), glucose tolerance, glucagon-like peptide-1 (GLP-1) levels, and insulin sensitivity were evaluated.

RESULTS: SG significantly shortened operative time and post-operative recovery time compared to IT surgery (P<0.05). SG and IT surgery resulted in significantly induced weight loss, significantly decreased levels of glucose, and significantly enhanced levels of Ghrelin compared the Sham surgery group (P<0.001). SG and IT surgery resulted in significantly increased GLP-1 levels compared to Sham surgery (P<0.001). SG resulted in better reduction of oral glucose tolerance test (OGTT) glucose compared to IT surgery (P<0.05). SG and IT surgery significantly upregulated insulin tolerance test (ITT) levels compared to Sham surgery (P<0.001). SG induced better reductions in TC and TG compared to IT surgery (P<0.05).

CONCLUSIONS: In non-obese rats with spontaneous diabetes, both SG and IT surgery were found to control diabetes by regulating body weight and levels of glucose, Ghrelin, GLP-1, OGTT glucose, insulin, TC, and TG. Moreover, SG demonstrated advantages of shorter operative time, shorter post-operative recovery time, and better control of diabetes compared to IT surgery.
