Abstract
Endoscopic retrograde cholangio-pancreatography (ERCP) and pancreozymin secretin test (P-S test) were performed in 90 patients with chronic pancreatitis and ERCP findings were compared with values of P-S test for the study of correlation between these two exami-nations, and discussions were made on diagnostic evaluation of ERCP in chronic pancreatitis. Cases studied include histologically diagnosed cases, chronic calcifying pancreatitis, cases showing abnormal P-S test and cases of suspected chronic pancreatitis with upper abdominal discomforts and elevated serum or urinary amylase. 47 out of 54 cases with definite chronic pancreatitis showed abnormal P-S test and, on the other hand, ERCP revealed abnormalities in all of these cases. Statistical study indicated that the values in P-S test were well correlated with ERCP findings in grade of their ab-normalities. However, the discrepancy between ERCP findings and P-S test values was observed in nine cases. Four were cases of biliary tract diseases with or without gall stones. One was of unknown etiology and the rest four cases had chronic calcifying pancreatitis, in which stones were located mainly in large pancreatic duct.
