[Diagnostic and therapeutic possibilities of interventional echotomography in gastroenterology].
Interventional ultrasound includes all diagnostic and therapy procedures controlled by ultra sound. In this manner, conventional ultrasound diagnostics which has a very important diagnostic role in gastroenterology increases its potential in diagnosis and gives an important contribution in the therapy of abdominal organs diseases. Diagnostic interventional ultrasonography enables sampling from solid and cystic changes for histological or cytological analyses. This procedure enables a more precise injection of contrasts in biliary or pancreatic ducts in the situations when it cannot be done by ERCP. Potential of interventional ultrasonography in the therapy is seen in the possibility to place the needle or the catheter into cystic and abscess changes in order to drain pathological collections and inject medicaments into pathological changes. The procedure is relatively simple and therefore considerably less aggressive compared to surgical treatment. Being very economic and efficient it became an important method in diagnostics and therapy of gastroentrological diseases.
