Abstract
Background
Dual-path side-to-side jejunoileal bypass (SSJIB) can markedly ameliorate diabetes and obesity. However, whether SSJIB requires the ligation of the bypassed loop (single-path) and what is the most appropriate length of the bypassed small bowel remain unknown. The aim of this study was to evaluate the role of ligation and the length of the bypassed small bowel in mediating changes in glucose homeostasis after SSJIB in streptozotocin (STZ)-induced diabetic rats.
Methods
Fourteen STZ-induced diabetic rats were randomized into two groups: one group was subjected to 50% SSJIB (SSJIB-50 group) and one group was subjected to sham surgery (sham group). Three weeks later, the SSJIB-50 group was re-operated, and the bypassed segment was ligated (SSJIBL-50 group). Three weeks later, the SSJIBL-50 group was operated again, and 60% of the length of the proximal small intestine was bypassed (SSJIBL-60 group). The measured primary outcomes were body weight, food intake, fasting blood glucose (FBG), and oral glucose tolerance test (OGTT).
Results
Body weight in the SSJIBL-60 group was lower than that in the sham group. Food intakes in the SSJIBL-50 and SSJIBL-60 groups were lower than that in the sham group. FBG and OGTT were not improved in the SSJIB-50 group compared with the sham group. However, FBG and OGTT were improved in the SSJIBL-50 group and were further improved in the SSJIBL-60 group.
Conclusions
Ligation of the first portion of the bypassed loop is essential to SSJIB, and bypassing approximately 60% of the small intestine length may be appropriate in SSJIBL.
