Bile Duct Stricture Shown During Transhepatic Cholangiography by Use of Cholecystokinin

THE HORMONE cholecystokinin (CCK) has been used to show gallbladder contraction during cholecystography (following oral ingestion of contrast material). We report the case of a patient with a stricture of the common bile duct in whom CCK was used during transhepatic cholangiography a case of gastric heterotopic pancreas giving rise to a nonislet cell pancreatic carcinoma. A of other reported cases of pancreatic cancer thought to have arisen from gastric heterotopic pancreas is given and a plan for surgical manage-ment is recommended.
