A novel computer-based simulator effectively trains surgeons in pelvic lymph node dissection (PLND), outperforming traditional methods and enhancing anatomical knowledge for improved surgical education.

Area of Science:

  • Medical Education Technology
  • Surgical Simulation
  • Urologic Oncology Training

Background:

  • Work-hour restrictions necessitate innovative surgical skills training methods.
  • Technological advancements are transforming medical education.
  • Need for validated tools to teach complex procedures like pelvic lymph node dissection (PLND).

Purpose of the Study:

  • To evaluate the validity of a novel, computer-based, interactive cognitive simulator for PLND training.
  • Assess the simulator's utility in enhancing surgical expertise and anatomical understanding.

Main Methods:

  • Eight prostate cancer experts reviewed simulator content and rated contextual aspects.
  • Experts and nine first-year residents performed a simulated PLND.
  • Performance metrics (time, deviations) were compared between experts and novices using the Mann-Whitney test.

Main Results:

  • 100% of experts found the simulator more useful than standard video training post-evaluation.
  • Experts reported enhanced understanding of PLND indications, steps, anatomy, and assistant utilization.
  • Median PLND times: 12.62 minutes for experts vs. 23.97 minutes for novices; deviations: 24.5 for experts vs. 89 for novices.

Conclusions:

  • An interactive, computer-based simulator effectively aids mastery of cognitive steps in open surgical procedures.
  • The platform is intuitive, flexible, and applicable to various stepwise medical procedures.
  • Experts significantly outperformed novices, validating the simulator's effectiveness in surgical training.
