Abstract
A 57-year-old male visited our hospital for further examination of periodic health check-up. Abnormalities checked were abnormal folds on upper GI series, liver damage, hypertriglyceridemia and abnormal O-GTT. UGI series showed calculi in the duodenal loop. High density areas were subsequently confirmed in the pancreatic uncinate on CT. ERP demonstrated smooth stenosis of the duct of Santorini and dilatation and filling defects in a branch. It is suggested that pancreatic calculi might be formed by stasis of pancreatic flow in the branch associated with congenital or acquired stenosis of the duct of Santorini.
