title: Combined approach to the differential diagnosis of cholestatic jaundice with endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, ultrasonography, and liver biopsy.
abstract: A prospective study of 33 patients with cholestatic jaundice was performed with combined use of endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), ultrasonography, and liver biopsy. A higher rate of success with PTC in 25 cases of extrahepatic cholestasis was offset by the better score of ERCP in 8 cases of intrahepatic cholestasis and its wider diagnostic scope. The procedures were complementary in 10 cases. Ultrasonic imaging of intrahepatic bile ducts proved useful for selecting the first cholangiographic technique. Liver biopsy established etiology in intrahepatic cholestasis. Our combined approach allowed us to develop through objective criteria a diagnostic flow chart of cholestasis.
