title: [Use of ultrasound tomography in the control of endoscopic retrograde bile duct drainage].
abstract: The sonography of three patients with a transpapillar catheter within the bile duct shows typically findings as the picture of catheter as a tubular structure with high level reflectivity, reduction of bile duct calibers and air in the bile ducts. The diminuation of the bile duct calibers is an argument for normal transpapillary bile flow and occurs before the change of laboratory parameters. In case of jaundice the differentiation between metastatic tumours of the liver and occlusion of the catheter is possible on the basis of ultrasound. After the diminuation of calibers of the bile ducts a metastatic tumours of liver are better to be seen.
