BACKGROUND: Tumor burden is difficult to estimate by endoscopy and conventional EUS.
OBJECTIVE: The purpose of this study was to determine the accuracy and the reliability of a
new 3-dimensional (3D) EUS system in a pseudotumor model (Olympus EUS EXERA EU-
M60). DESIGN: A pseudotumor model was developed in a porcine stomach. Pseudotumors
were created by injecting various volumes of US gel (0.3, 0.5, 0.7, and 1 mL) into porcine
stomach specimens, and then the volume was measured in vitro. Two investigators made …
