[The chologon-sorbitol functional test under ultrasonic control in pathology of the gallbladder and biliary tract].

The degree of the filling up and the dilation of the gall bladder, its functional state as well as the passibility of d. cysticus are evaluated by ultrasound examination and computer determination of the surface and dimensions of the gall bladder. 546 patients, 20-78 years of age (484 women and 62 men) were examined by a pharmacodynamic functional test with chologon (acidum dehydrocholicum) in a dose of 10 mg/kg body mass and sorbitol (in 116 patients) in a dose of 20 g in 100 ml of water. The functional test is easily performed in the course of the ultrasound examination and side effects were registered. The test allows the assessment of the functional state of the gall bladder, the passibility of d. cysticus, the degree and mechanism of the filling up of the gall bladder and the bile ducts with bile. The better filling up of the gall bladder with bile after application of chologon (by passable d. cysticus) ensures better conditions for detecting microgallstones in the gall bladder as well as of diseases linked with its wall--cholesterosis, cancer and polypi of the bladder, etc.
