Abstract

Thirty four consecutive patients suspected of having pancratic neoplasm were taken endoscopic ratrogradecholangio-pancreatography(ERCP) and ultrasonography and CT. The results were as follows; 1. The age distributionranged from 21 years to 70 years. Among them the most common age group was between 41 years and 50 years. The maleto female ratio was 1.6;1. 2. The results of ERCP were 65% accurate, 6% false negative and 29% failure. ExcludingERCP diagnosis was accurate in 83%. 3. The results of CT were 74% correct, false negative 12%, false positive 6%,and 8% indeterminate. The rate of false negative and false positive were more high in CT as compared with ERCP.However, due to the greater frequency of examination failures with ERCP, its greater cost and invasiveness, andhigh incidence of nonpancreatic disease found on CT, it appears that CT scanning is more suitable for initialscreening of patients suspected of having pancreatic neoplasm. 4. The results off ultrasonography were 59%correct, false negative9%, false positive 3%, 29% indeterminate. When evaluating pancreative cystic lesions, itthinks that US is most suitable and accurate. 5. When CT and ERCP findings were identical, the accuracy rate was89%. Combined use of ERCP-CT examination were often complementary and generally led to more accurate and specificdiagnosis.
