title: [Ultrasonics in the modern diagnosis of biliary tract diseases].
abstract: The ultrasound diagnostics is of high value in revealing the diseases of the biliary ducts. Prerequisite for an exact diagnosis is an exact knowledge of the arterial, venous and biliary vascular systems of the porta hepatis. Using real-time-devices a differential diagnosis of these several systems can quickly be made in systematic examination. The examination is indicated at suspicion for cholelithiasis, cholecystitis, choledocholithiasis and obstructive jaundice. The differential diagnostic criteria are demonstrated. The number of success in cholecystolithiais for the ultrasound diagnostics is at present 93%. In differentiation of the obstructive jaundice it is about 85%.
