Virtual reality (VR) training can effectively measure laparoscopic surgical skills. This study found significant correlations between VR performance and actual surgical tasks, suggesting VR as a viable metric for surgical ability.

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Virtual Reality Technology

Background:

  • Assessing surgical skills, particularly laparoscopic techniques, is challenging and lacks standardized metrics.
  • Virtual reality (VR) has emerged as a tool for surgical training.
  • This study explored VR's potential for objective measurement of laparoscopic ability.

Purpose of the Study:

  • To evaluate the efficacy of a virtual reality simulator in assessing laparoscopic surgical skills.
  • To determine if VR performance metrics correlate with performance in animate surgical tasks.

Main Methods:

  • Medical students with no prior laparoscopic experience performed tasks in a porcine model and on a Minimally Invasive Surgery Trainer-Virtual Reality (MIST-VR) system.
  • Performance was assessed by task completion time and economy of movement.

  • MIST-VR scores for individual hands were compared with animate lab results.

    • Main Results:

    • Thirty-two students participated, with statistically significant correlations found between VR metrics and operative tasks.
    • A majority of the 16 possible relationships between VR performance and surgical tasks showed significant correlation (P < 0.05).

    Conclusions:

    • Virtual reality simulation shows promise as a tool for measuring laparoscopic surgical ability.
    • Despite not all correlations being significant, the majority indicate VR's potential for objective skill assessment.
