N/A In 149 patients with the pancreatic or biliary diseases including CBD stone, CBD cancer, pancreatic cancer and chronic pancreatitis, diagnostic values of clinical criteria, ultrasonography and ERCP were reviewed by the calculated sensitivity, specificity, predictive value positive and negative. The results are summarized as following; 1) Sensitivity, specificity, predictive value positive and negative of malignant clinical criteria were 67.9%, 83.9%, 71.7% and 81.3% respectively, while those of benign clinical criteria were 83.9%, 67.9%, 81.3%, 71.7% respectively. 2) Sensitivity, specificity, predictive value positive and negative of ultrasonography in detecting pancreatobiliary abnormalities were 71.7% 77.3%, 94.5%, and 32.1%, respectively. 3) Sensitivity, specificity, predictive value positive and negative of ERCP for diagnosis of CBD stone were 88.6%,98%, 97.8% and 98% respectively, and for CBD cancer 65%, 94.7%, 76.5% and 97.3% respectively, and for pancreatic cancer, 78.3 % 97.7 % 90% and 96.6% respectively, and for chronic pancreatitis, 85.7%, 99.0%, 85.7% and 99.0% prespectively. Predictive value positive of ERCP for diagnosis of CBD cancer is relatively low. In conclusion, clinical criteria still have quite significances in differentiating between malignant and benign diseases of pancreatobiliary tract, and ERCP shows high diagnostic values in patients with CBD stone, CBD cancer, pancreatic cancer and chronic pancreatitis. But the predictive value positive was relatively low for diagnosis of CBD cancer. Therefore, other additional diagnostic tests such as cytology of bile juice are necessary to increase the dialgnostic value of ERCP for CBD cancer.
