title: [Doppler echography for the preoperative assessment of malignant processes in the pancreas head and liver hilus].
abstract: Ultrasound is the imaging technique of choice in obstructive jaundice for demonstration of dilatation of the bile ducts, and its position and cause. In carcinoma of the pancreatic head and in hilar tumours of the liver (Klatskin) it is often possible to demonstrate their inoperability, making other imaging techniques unnecessary. Duplex-Doppler ultrasound can be highly advantageous in the evaluation of compression or invasive growth of the tumour in the mesenterico-portal venous system, making such invasive examination procedures as angiography unnecessary.
