Virtual reality trainers do not significantly alter laparoscopic skills acquisition compared to inanimate box trainers alone. Both training methods yield similar results in skill development for novice surgeons.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Education
  • Medical Simulation

Background:

  • Inanimate box trainers are standard for basic laparoscopic skills.
  • Virtual reality (VR) trainers may lack tactile feedback, potentially hindering skill transfer.
  • This study investigates VR's impact when supplementing traditional methods.

Purpose of the Study:

  • To test the hypothesis that VR trainers do not affect laparoscopic skills acquisition compared to inanimate trainers alone.
  • To evaluate the efficacy of a blended VR and inanimate training approach.
  • To compare skill development in novice laparoscopic surgeons using different training modalities.

Main Methods:

  • Medical students without prior laparoscopic experience were randomized into two groups.

  • Group A trained solely on an inanimate box trainer (LTS 2000).
  • Group B trained on both the inanimate box trainer and a VR trainer (MIST-VR).
  • Performance was assessed on 5 inanimate trainer exercises, comparing the first and tenth sessions for time and errors.

    • Main Results:

    • No significant differences in time or errors were observed between groups in the initial or final sessions.
    • Both groups showed improvement in exercise times from the first to the last session.
    • Laparoscopic skills acquisition was comparable between the group using only inanimate trainers and the group using a combination of inanimate and VR trainers.

    Conclusions:

    • Incorporating VR trainers into a curriculum primarily using inanimate box trainers does not alter laparoscopic skills acquisition.
    • Both training modalities are effective for developing foundational laparoscopic skills.
    • Surgical training laboratories may benefit from including both VR and inanimate trainers for comprehensive skill development.
