ERCP was performed in 38 cases of clonorchiasis of the liver, which was confirmed by stool egg test withStoll's dilution method from Apr. 1979 to Oct. 1982. The resuls were as follows 1. The sex distribution ofclonorchiasis showed marked male predominance by 97.4% and age distrigution were higher in 5th and 6th decades. 2.Multiple small filling defects in the intrahepatic bile duct was the most characteristic finding in ERCP and widespread irregular stenosis, dilatation of terminal portion, disturbance of peripheral filling, fuziness andraggedness of intrahepatic duct were also noted. 3. The severity of clonorchiasis by ERCP were classifed asfollows; Grade I-7 cases (18.4%), GradeII-9 cases(23.7%) Grade III-12 cases (31.6%) and Grade IV-10 cases(26.3%)4. Chronic cholecystitis 10 cases(26.3%), Billary tree stone 7 cases (18.4%), malignancy of distal CBD 1 case(2.6%) were found with clonorchiasis by ERCP. 5. Three cases, treated with Niclofolan, showed marked improvementof pathology on follow-up ERCP.
