[Choleretic test in the ultrasonic diagnosis of cholelithiasis].

The authors provide the results of repeated echography of the gall bladder after the use of choleretics in cases presenting difficulties for echographic diagnosis of concrements inside the organ. Describe the technique of making the choleretic test, define indications and contraindications as to its use. Ultrasonic exploration of the gall bladder after choleretic intake raises the accuracy of echographic diagnosis of cholelithiasis, reduces the time required for echocholecystography, helps make differential diagnosis of the gall bladder diseases.
