Pharmaco-cholecystosonography by administration of dehydrocholic acid was performed in 14 normal subjects and 52 patients with gallbladder diseases. Thirty minutes after administration, a normal gallbladder showed enlargement of the size compared with that before. Enlargement ratio was 185±36% (M±S.D.).
Pharmaco-cholecystosonography was effective for evaluation of cystic duct patency. The improved diagnosis was obtained in 9 out of 21 patients with gallbladder identified with difficulty or not identified on ultrasonogram. Pharmaco-cholecystosonography may be usefully applied when conventional sonography failed to demonstrate the lumen of the gallbladder clearly.
