Linear array echoendoscopy in cancer management

摘要

Endoscopic ultrasonography provides the endosonographer the best of both worlds. Not only can one visualize structures endoscopically, but also one can see through the gut wall and better define the extent of disease and more effectively plan therapy. Linear array echoendoscopy produces a scanning plane, which is parallel to the the long axis of the endoscope. Hence, endosonography-guided fine needle aspiration biopsy (EUS FNA), endosonography-guided fine needle injection (EUS FNI), duplex endosonography, and endosonography -guided celiac plexus neurolysis (EUS CPN) can be performed. The role of linear array echoendoscopy in cancer staging and management will be critically reviewed.
