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.
