[Ultrasonic diagnosis of biliary tract dyskinesia]

Ultrasonic sectoral scanning was used to determine the type of biliary tract dyskinesias in the course of digestion. 89 patients with different gastroenterological diseases were examined. 21 healthy subjects made up the control group. The process of gallbladder contraction was conventionally divided into 3 phases. In practically healthy subjects, the first phase was marked by gallbladder contraction from the neck down to the bottom while the gallbladder assumed an optimally suitable form for prolonged contraction. The second phase involved rapid contraction (during 15 min the gallbladder size reduced by 28.8%). The third phase involved slow contraction (during 30 min the gallbladder decreased in size by another 29%). 5 types of dyskinetic disorders were distinguished. This permitted diagnosing the focus of pathology within the system of the biliary tract together with administering the differentiated treatment.
