Abstract
- Linear array echoendoscopes were developed in the early 1990s and they have facilitated performing EUS-guided interventional procedures. The introduction of linear array echoendoscopes allows performing fine needle aspiration because the device enables tracing the path of the tip of the needle during puncture procedure. In addition to being very useful for diagnostic purpose, this device enabled us to develop various therapeutic endoscopic procedures. Therapeutic drainage procedures, including EUS-guided bile duct drainage, pancreatic pseudocyst drainage and pancreatic duct drainage, have all been more frequently performed in the last decade. In addition to the acquisition of tissue or fluid, various substances can be delivered into the target areas with EUS, with an example being an EUS-guided celiac plexus neurolysis/block. In this review, we describe the present place and role of interventional EUS in clinical practice.
