title: [The diagnostic performance of echography and CT in pancreatic diseases producing extrahepatic cholestasis].
abstract: A hundred and fifty patients with jaundice and analytical suspicion of extrahepatic cholestasis were studied prospectively; history, laboratory investigation and ultrasound examination were realized. Computerized tomography was performed in 146 patients. Ultrasonography and computerized tomography findings were confirmed by CPRE o CPTH and surgery. Ultrasonography has a sensitivity of 92.6% while that of computerized tomography was 87.2% for the identification of dilated biliary ducts. The accuracy of ultrasonography was higher than the one obtained in computerized tomography in cholangiocarcinoma (sensitivity: 77.7%) and gallbladder carcinoma (sensitivity: 100%). Computerized tomography recognized choledocholithiasis (sensitivity: 83.3%) and ampullary carcinoma (sensitivity: 88.8%) with better accuracy. However for pancreatic carcinoma (sensitivity: 88.8%) and pancreatitis (sensitivity: 83.3%) both examinations had the same accuracy.
