title: [Duplex sonography in gastroenterology].
abstract: Blood flow in vessels and organs can be examined noninvasively by conventional and colour-coded duplex sonography. This method is very practicable in portal hypertension, portal thrombosis and Budd-Chiari-Syndrome. Stenosis and occlusion of the coeliac trunk and the superior mesenteric artery can be detected. In the future duplex-sonography might be of importance in the differential diagnosis of space occupying lesions. Quantitative blood flow measurement is unnecessary in daily practise but is successfully used in scientific work.
