Simulation of Endoscopic Ultrasound (EUS)

  • For the simulation of EUS, a partial gastrointestinal tract explant is used and suspended in water or ultrasound gel as a conduction medium.  Pathologies that are created using proprietary techniques developed by Endosim are placed at specific locations on the explant. These cysts can be identified by linear or radial EUS and the fluid can be aspirated by EUS-guided FNA. The esophagus or colon can be chosen as entry points.
  • For diagnostic EUS, all sections of the gastrointestinal tract, the liver, the pancreas, and the kidneys can be identified. Submucosal depots can be created by external injection of colloid depots. A solid mass can be created by surgical implantation. This intramural lesion can be examined by EUS and the relationship to the mucosal and muscular layers of the gastrointestinal tract can be interpreted.

Below are images of EUS specimens using up to 6 different pathologies.
