Abstract:
Objective To explore the feasibility of establishing the model of chronic blliary(pancreatitis) by incompletely ligaturing common bile duct.Methods Fifty Wistar rats were randomly(divided) into three groups: control group,experimental control group and model group.The rats in model group were exposed the root of common bile duct to enter duodenum using the dissolubility bowel line to ligating a needle with common bile duct,then drew out the needle,closing the abdominal cavity.The rats in experiment control group were opened the abdominal cavity and dissociated common bile duct,then closing the abdominal cavity.Results Compared with control group,the serum bilirubin and(amylase) of blood in model group were increased in 3 days and 14 days respectively and fibrotic(proliferation) of pancreatic tissues were found in 30 days.In model group,23% of rats developed(pancreatic) pseudocyst.Conclusions Incompletely ligating the common bile duct of Wistar rats could(induce) chronic pancreatitis and pancreatic fibrosis in 30 days.Strictures of common biliary duct may play a key role in chronic biliary pancreatitis.
