Short-Term Results Suggest That Sleeved Stomach without Resection Is as Effective as Sleeve Gastrectomy in Improving Glucose Control in Type 2 Diabetes Mellitus Sprague-Dawley Rat Model

الملخص EN

Background.

Although sleeve gastrectomy results in good weight loss and metabolic improvements, it is an irreversible procedure.

Therefore, we attempted to assess the possibility of creating a sleeved stomach without resection.

Material and Methods.

A total of 22 male Sprague-Dawley rats with type 2 diabetes were randomly assigned into 3 different groups: (1) sleeve gastroplasty with gastric remnant-jejunal anastomosis (SGP, n=8); (2) sleeve gastrectomy (SG, n=8); and (3) SHAM (n=6).

Body weight, food intake, fasting blood glucose (FBG), hormonal analysis, and oral glucose tolerance test (OGTT) were performed and measured preoperatively and postoperatively.

Results.

During the postoperative period, SGP and SG showed significantly lower food intake and body weight when compared with the preoperative levels, respectively (p value < 0.05).

Postoperatively, SGP and SG showed improvements in FBG and glucose tolerance levels compared to their respective preoperative levels (p<0.05).

FBG and glucose tolerance levels did not differ between SGP and SG postoperatively.

SG resulted in a reduction in fasting ghrelin levels when compared with the preoperative level (p<0.05).

Fasting insulin levels did not differ preoperatively and postoperatively among all groups.

Postoperatively, fasting GLP-1 levels were higher in SGP and SG when compared with the preoperative levels, but no statistical significance was observed.

Compared preoperatively, the SGP and SG procedures resulted in a decline in HOMA-IR at postoperative 6th week (p<0.05).

Conclusion.

Our animal experiment suggested that at least in the short term, sleeved stomach without resection resulted in similar weight loss and improved glucose control effects compared to sleeve gastrectomy.
