OBJECTIVE: The present study compared the therapeutic effects of great curvature plication with duodenal-jejunal bypass (GCP-DJB) and the commonly used sleeve gastrectomy (SG) in rats with type 2 diabetes mellitus (T2DM).
METHODS: The rats were randomly divided into three groups: Control group (n = 6), SG group (n = 6), and GCP-DJB group (n = 6). Body weight, daily food intake, fasting blood glucose level, fasting insulin level, insulin resistance index, and fasting serum concentrations of glucagon-like peptide-1 (GLP-1), peptide tyrosine tyrosine (PYY), and bile acid were measured. In addition, postoperative changes in body weight and daily food intake at 2, 4, 6, 8, 10, and 12 weeks were also recorded. At week 12, an oral glucose tolerance test (OGTT) and insulin release test were performed to determine glucose tolerance. The insulin resistance index (IRI) was also measured. The postprandial secretion curves and area under the curve (AUC) of GLP-1, gastric inhibitory polypeptide (GIP), PYY, and bile acid were also calculated.
RESULTS: Before surgery, no significant differences in body weight, daily food intake, fasting blood glucose, fasting insulin, insulin resistance index, fasting GLP-1, PYY, and bile acid were found among the three groups (P > 0.05). At postoperative week 12, body weight and food intake in the SG and GCP-DJB groups were lower than those in the Control group (P < 0.05), and body weight in the GCP-DJB group was lowest (P < 0.05). Glucose tolerance, postprandial serum insulin (INS), GLP-1, PYY, and bile acid were significantly higher in the SG and GCP-DJB groups than in the Control group (P < 0.05). The parameters related to glucose metabolism in the GCP-DJB group were higher than those in the SG group with the exception of serum insulin (P < 0.05). In addition, IRI and GIP secretion were significantly lower in the SG and GCP-DJB groups than in the Control group (P < 0.05) and were lowest in the GCP-DJB group (P < 0.05).
CONCLUSION: Both GCP-DJB and SG are surgical options for the treatment of T2DM. The underlying mechanism of these treatments may be related to the decrease in body weight, food intake, GIP, IRI, and the increase in INS, GLP-1, PYY, and bile acid. According to the various metabolic indicators related to the hypoglycemic effects in T2DM, GCP-DJB was superior to SG.
