Abstract

PURPOSE
To evaluate the diagnostic accuracy of T-tube cholangiography(TTC), selective cholangiography (SC) and noncontrast CT(NCT) in the evaluation of intrahepatic stone disease.
MATERIALS AND METHODS
We retrospectively analyzed the radiological findings of these methods in thirty patients with intrahepatic stones proved by percutaneous removal. Findings of each procedure were reviewed and correlated with findings of stone removal procedure.
RESULTS
Detection of stones was possible in 87. 0% for TTC, 90. 0% for SC, 96. 7% for NCT(p > 0.05). Selective cholangiography was as good as or superior to 1-I'C in determining the presence and extent of the stones in all patients(p < 0. 01). NCT was better than SC in 9;as good as SC in 18;inferior to SC in 3 patients in determining the extent and location of the stones(p > 0.05). Of 12 patients who had additional findings such as biliary cirrhosis or accompanied cholangiocarcinomas, only NCT could detect the lesions in 11 patients.
CONCLUSION
Although there was no statistically significant difference between NCT and SC, one procedure sometimes gave valuable informations for interventional procedure which the other could not. Thus we conclude that both procedures are complementary studies and should be done in all patients who are subjected to biliary intervention.
