Purpose:
To develop a non-obese diabetic rat model for sleeve gastrectomy with modified jejunoileal bypass (SG/MJIB) and to investigate its effectiveness and safety for inducing diabetic control.
Materials And Methods:
Thirty-five 13-week-old male Goto-Kakizaki rats were randomly assigned to the pair-fed to sham-operated SG/MJIB (PFSO-SG/MJIB), SG/MJIB, PFSO-SG, SG, and control groups. The experimental period was 16 weeks post-operatively. Body weight; food intake; glycemic control outcomes; and ghrelin, glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), and insulin levels were measured.
Results:
The operated and PFSO groups showed significant weight loss 4 weeks post-operatively compared to the control. The SG/MJIB and SG groups exhibited a significant improvement in oral glucose tolerance and insulin tolerance compared to the PFSO and control groups. The improved effects in the SG/MJIB group were better than those in the SG group. The SG/MJIB and SG groups showed decreased fasting ghrelin levels and increased levels of GLP-1 secretion 2 and 16 weeks post-operatively. Compared to the SG group, only the SG/MJIB group showed higher glucose-stimulated GLP-1 levels and significantly improved insulin secretion.
Conclusion:
SG/MJIB may be an effective, steady hypoglycemic surgical model, showing better diabetic control than SG. The hindgut may play a direct role in ameliorating glucose homeostasis.
