Effect of vagotomy on acute pancreatitis in rats

Abstract

One hundred and eighty-two SD rats were randomly divided into the normal control group, fast operating group and food-intake operating group. The experimental model of acute pancreatitis (AP) in rats was established by injecting 5 % sodium taurocholate into the pancreatic duct of rat according to Aho’s method. The sandostatin was used for positive contrast. The concentrations of serum amylase, calcium, C reaction protein (CRP) and interleukin-6 (IL-6) were assayed respectively at different time points. The pathological sections were observed. Each operating group contained 10 rats. The mortality of the operating groups was observed during the 24 h. The serum amylase level in the AP rats was reduced after receiving vagotomy (VG,P < 0.05). Although the serum calcium level in most groups was decreased, the reduction in the group with VG plus sandostatin was not obvious (P > 0.05). The increase of CRP and IL-6 was not obvious after VG (P > 0.05). The change of mortality was not significant (P > 0.05). The pathological sections showed that the AP pathological change was mild after VG. The disease condition of food-intake operating group was more serious than that of fast operating group. It was suggested that VG had some influence on the prognosis of AP in rats.
