EUS-FNI of ethanol ablation of the orthotopic human pancreatic cancer cell mouse xenografts. (a) Preinjection. To ablate the orthotopic pancreatic cancer cell mouse xenograft, a fine needle was inserted into the xenograft lesion. (b) Postinjection. 80% ethanol was injected into the xenograft. Immediately after the injection of 80% ethanol, a hyperechoic area was noted in the tumor lesion.
