Influence of bile flow interruption on acute experimental pancreatitis.
The influence of bile flow interruption on the pathogenesis of acute pancreatitis has been evaluated in the rat. The pancreatitis was induced by Pfeffer's technique and the severity of the disease was assessed by a macroscopic examination of the pancreatic damage and the calculation of amylase-to-creatinine clearance ratio (ACCR) as well. The results showed that the bile reflux into the pancreas made the pancreatic lesions caused by stasis in the gland associated with hyperstimulation of exocrine secretion more severe. On the other hand the bile reflux had no influence when the pancreatitis was due to flowing back of duodenal contents into the pancreas (closed duodenal loop). It was concluded that the bile effect is probably consistent with a pressure mechanism. In addition the reliability of ACCR in the diagnosis of acute pancreatitis was confirmed, and the test was effective in detecting even milder pancreatic damages.
