Area of Science:

  • Surgical Education
  • Medical Simulation
  • Anatomical Modeling

Background:

  • Surgical training requires realistic anatomical experience.
  • Cadavers complement artificial models but may need tumor simulation.
  • Developing effective tumor mimics is crucial for surgical practice.

Purpose of the Study:

  • To create an easy-to-produce, realistic artificial tumor mimic.
  • To enhance peripheral lung tumor resection practice using cadavers.
  • To evaluate the fidelity of the artificial tumor models.

Main Methods:

  • Barium sulfate-enriched silicone was injected into 10 human cadaver lungs to create artificial lesions.
  • Computed tomography (CT) scans were analyzed post-fixation.
  • Tumor mimics were examined after anatomical preparation and slicing.
  • CT-guided percutaneous puncture was used to create lesions in situ in two additional cadaver lungs.

Main Results:

  • Out of 40 created lesions, 85% were nodular, with 12.5% showing spiculated features.
  • Satellite lesions occurred in 5% of cases.
  • 12.5% of lesions showed relevant outflow into vessels or airways.
  • 27.5% of lesions reached the lung surface.
  • Lesions were elastic, adhered well, and percutaneously implanted lesions were nodular with some lobulated features.

Conclusions:

  • The artificial tumor mimics are simple to create and exhibit varied shapes and sizes.
  • Percutaneous implantation provides a realistic model for teaching all surgical procedure steps.
  • This simulation enhances surgical training for lung tumor resection.
