ABSTRACT
OBJECTIVE:
To evaluate the effects of jejunal-ileal bypass(JIB) in addition to sleeve gastrectomy(SG) on glycemic regulation and body weight in Zucker Diabetic Fatty(ZDF) rats and underlying mechnisms.METHODS:
Twelve ZDF(fa/fa) rats were randomly divided into two groups based upon the procedure performed including sleeve gastrectomy plus jejunal-ileal bypass surgery group(SG+JIB,n=6) and sleeve gastrectomy plus sham procedure group(SG+Sham,n=6). In addition,five healthy ZDF(fa/+) rats were employed as normal controls. Body weight,fasting blood glucose,food intake,oral glucose tolerance test and plasma GLP-1 levels were measured before surgery and at 2 and 4 weeks after surgery.RESULTS:
Preoperatively,all baseline parametes had no statistical difference between SG+JIB and SG+Sham groups. In comparison with SG+Sham group,fasting plasma glucose levels at postoperative week 2(17.3 mmol/L vs. 8.7 mmol/L) and 4(21.4 mmol/L vs. 11.9 mmol/L)were significantly lower in SG + JIB group(P<0.0001). Oral glucose tolerace was significantly improved,represented by glucose excursion area under curve for 180 minutes period(4221 vs.2964,P<0.0001 at postoperative week 2;and 4104 vs. 3388,P<0.01 at postoperative week 4). Simutaneously,plasma GLP-1 levels were significantly higher in SG + JIB group than SG + Sham group(64.58 pmol/L v.s.30.52 pmol/L,P<0.001). However,SG + JIB had less food intake and body weight only decreased at postoperative week 2,but not at week 4.CONCLUSION:
By adding JIB onto SG,the metabolic regulation capability is able to be furtherly enhanced. However,it seems that there is not additional benefit in weight loss.Therefore,based upon these results,we suggest that SG + JIB should be recommended to the patients who needs additional metabolic effects,but not to the patients for the purpose of additional weight loss above SG alone.
