CHRONIC BILIARY-TYPE PAIN IN THE ABSENCE OF GALLSTONES - THE VALUE OF CHOLECYSTOKININ CHOLESCINTIGRAPHY

Radiologic criteria for the diagnosis of gallbladder disease largely rest on the detection of calculi. Surgeons are reluctant to do a cholecystectomy in patients with symptoms of gallbladder disease if the results of sonography or cholecystography are normal. Consequently these patients are often left with no satisfactory treatment. Such patients may have chronic acalculous cholecystitis, partial obstruction of the cystic duct, or gallbladder dyskinesia. Increasing evidence indicates that at least some of these patients have decreased gallbladder emptying in response to a stimulus such as a test meal or cholecystokinin. Impaired emptying shown by cholecystokinin cholescintigraphy may be useful for predicting which patients with typical biliary-type pain but no evidence of calculi will be cured by cholecystectomy.
