RESUMEN
Objective To probe the changes of CT values in liver parenchyma in order to evaluate the therapeutic effect of acute pancreatitis.Methods 104 patients with acute pancreatitis which were diagnosed and treated by department of gastroenterology.Ac-cording to pathological results,the patients were divided into mild acute pancreatitis (MAP)group and severe acute pancreatitis (SAP)one.The CT values of liver parenchyma were measured before and after treatment,and the correlations between CT values changes and the amylase in blood and urine were analyzed.Results The CT values of liver parenchyma showed a negative correlation with the pathological severity of acute pancreatitis (r=-0.089,P <0.05).The accuracy using the changes of CT values to evaluate the therapeutic effect was significantly different between the MAP and the SAP group with different sensitivity of 92.2% and 85.7%and specificity of 33.3% and 94.1% respectively.In addition,the changed trend of CT values in liver parenchyma showed negative correlations with triglycerides and blood amylase.Conclusion CT scan is a useful imaging method in evaluating the liver damage and the therapeutic effect in patients with acute pancreatitis in emergency.
