| Résumé : | Great progress has been realised in the field of biliary obstruction diagnosis, thanks to new technics of investigation based on physical means. The efficacy of echography in the diagnosis of intra-abdominal space occupying lesions is already well known. Its possibility of structural analysis permits one to differentiate liquid collections from plain tumors and, thanks to this property, to distinguish a dilated gallbladder and demonstrate the presence of biliary lithiasis when I.V. cholangiography reveals only an exclusion of the gallbladder. Computerised tomography gives not only good morphologic information on intra-abdominal organs, but measures also some density of parenchyma. It permits one to differentiate a tumor tissue from the normal parenchyma. The biliary tree is easy to distinguish when dilated. Computerised tomography is able to localise the siege of an obstruction of the extra-hepatic biliary tree, as a neoplasm of the head of the pancreas. It helps to demonstrate the absence of any obstruction and to establish the diagnosis of cholestatic jaundice. Combined echotomography and computerised tomography have undoubtedly improved the viability of the diagnosis in pathology of the biliary tract. The non invasive character of both investigations is quite appreciated by the patients. |
