Abstract:
The authors analysed retrospectively 56 cases of bile duct cancer, which were confirmed by histologically in47 cases and highly suuspected by clinically and radiologically in 9 cases. The resutls were as follows: 1. Themost prevalent age groups were 5th decade and a male to female ratio is 2.7:1. 2. The location of bile ductcarcinomas were common bile duct in 36%, common hepatic duct in 25%, junction in 13%, porta haptis in 11% anddiffuse involvement in 5%. 3. The accuracy of predicting obstruction is by ultrasonography was 76%. 4. Correctdiagnosis as bile duct carcinoma was made in 29 cases(43%). 5. The echogenicity of bile duct carcinoma compare toliver parenchyme was hyperechoic in 10 cases(34.5%), isoechoic in 14 cases(48.3%) and hypoechoic in 5cases(17.2%). 6. Posterior acoustic shadowing was seen in 5 cases. 7. The shape of obstruction site was abruptcut-off in 12 cases(41%), funnel shape in 7 cases(24%) and indistinct in 10 cases(35%).
