Abstract

Diagnostic accuracy of ERCP, CT and US was studied in 50 cases of liver, biliary tract and pancreatic diseases. Furthermore, capabilities and limits of combined diagnosis of three examination methods was assessed. The incidence of diagnostic accuracy in combination of three methods of examination was 92% in 50 cases of liver, biliary tract and pancreatic diseases. Of 24 cases with liver and biliary tract diseases, 16 cases (67%) were capable to be diagnoned by ERCP, combined with CT diagnostic accuracy increased to 21 cases (88%). Moreover, the accuracy increased to 22 cases (92%) by adding US. In 26 cases of pancreatic diseases, the incidence of diagnostic accuracy of ERCP was 22 cases (85%), however it increased only by 7% adding CT and US. This increased incidence was lower than that (25%) of liver and biliary tract diseases. The diagnostic capacity of CT (15%) and US (15%) especially for chronic pancreatitis was low. In cases of malignant tumors of the liver, biliary tract and pancreas, diagnosis was possible in almost 100% using the three combined methods. However all these tumors were advanced. A reliable new method is to be developed especially for early detection of tumors in near future.
