[The value of ceruletide in oral cholecystography]

The action of Ceruletide, a decapeptide with a chemical formula close to that of the terminal acid amines of cholecystokinin pancreozymin, was investigated during oral cholecystography. Intramuscular injections of Ceruletide provoked gallbladder contractions that were stronger and occurred more rapidly than after the conventional "fatty meal". Visualization of the extrahepatic biliary pathways was improved, the duration of the examination shortened, and the number of films required reduced, the useful time in approximately 3 out of 4 cases being equal to or less than 6 minutes.
