Paper Abstract

The subject of the paper is devoted to a modern diagnostic method called the endoscopic ultrasonography (EUS) that is still not widely implemented in many countries. This method bases on two imaging techniques: videoendoscopy and ultrasonography, making possible effective aiding of diagnostics as well as evaluating possibilities of performing radical surgical therapy. Rotating USG probes enable acquiring images vertical to an axis for the round angle area. Small diameters and adequate frequencies of these microprobes make possible their deep penetration into such difficult sites as the biliary and pancreatic ducts. The EUS advantages are presented here on the basis of several examples of real minimally invasive interventions as well diagnostic procedures practiced by the authors. EUS has allowed precise diagnostics without disturbances occurring at conventional ultrasound imaging. The presented images concern EUS used for examination of different digestive tract diseases, including biliary and pancreatic ducts.
