The Early History of Interventional Endoscopic Ultrasound.

Technological advances in the field of endoscopic ultrasound (EUS) have emerged, especially in the past decade, that have rapidly expanded the therapeutic potential of EUS, largely through the innovations of accessory technology that could not have happened without innovative changes to echoendoscopes. As interventional EUS continues to evolve, further expansion into previously uncharted areas will most certainly happen.
