[The ultrasonic diagnosis of chronic cholecystitis using the choleretic test].

To raise the accuracy of ultrasonic diagnosis of chronic cholecystitis, it is suggested that the choleretic test designed by the author may be used, making it possible to study gallbladder extensibility. As many as 124 patients with chronic cholecystitis and 50 healthy persons were examined. In 63 patients, the diagnosis was verified morphologically after cholecystectomies. Chronic cholecystitis patients demonstrated the lowering of gallbladder extensibility, especially after atropine administration preceded by the use of dehydrocholic acid. Echography with the use of the choleretic test considerably raises the accuracy, efficacy, specificity and sensitivity of ultrasonic diagnosis of chronic cholecystitis.
