Cholecystokinin cholecystography in the diagnosis of gallbladder disease.

Twenty-six patients who had typical symptoms of biliary tract disease, e.g. postprandial right upper quadrant pain, nausea and vomiting, fatty food intolerance and flatulence and who had had two or more normal oral cholecystograms were subjected to cholecytokinin cholescystography. Ten patients showed a normal response to the intravenous administration of cholecystokinin, namely prompt and complete emptying of the gallbladder without producing any adverse reaction or symptoms. Sixteen patients demonstrated either no contraction or incomplete contraction of the gallbladder in response to cholecystokinin; several patients had moderate contraction of the gallbladder accompanied by symptoms of biliary colic. This latter group underwent cholecystectomy and operative cholangiography. Fifteen of the 16 patients are asymptomatic or improved, and only one patient continues to have symptoms. All removed gallbladders had histologic evidence of chronic cholecystitis. It is concluded that in some individuals with continuing symptoms suggesting gallbladder disease but normal oral cholecystograms, cholecystokinin cholecystography may be helpful in identifying physiologic dysfunction of the gallbladder.
