Laparoscopic simulation training effectively teaches surgical novices basic skills. While skills are retained for 6 weeks, deterioration occurs by 11 weeks, highlighting the need for ongoing practice.

Area of Science:

  • Surgical Education
  • Minimally Invasive Surgery
  • Medical Simulation

Background:

  • Simulation-based training is crucial for acquiring laparoscopic skills.
  • The long-term retention and deterioration patterns of these skills are not well understood.
  • This study investigates skill acquisition and retention following a laparoscopic simulation curriculum.

Purpose of the Study:

  • To evaluate the effectiveness of a 5-day laparoscopic simulation curriculum for surgical novices.
  • To assess skill retention at 6 and 11 weeks post-training.
  • To identify potential skill decay over time without continued practice.

Main Methods:

  • Thirty-six surgical novices completed a 9-skill laparoscopic curriculum.
  • Baseline, post-training, and retention evaluations (at 6 and 11 weeks) were performed.

  • Skill performance was measured by task completion time with accuracy penalties.

    • Main Results:

    • Significant learning was observed across all tasks post-training (P < .001).
    • Skills were largely retained at 6 weeks, with minimal decline in most tasks.
    • By 11 weeks, significant skill deterioration was noted in 5 out of 9 tasks (P ≤ .05).

    Conclusions:

    • Novices can acquire fundamental laparoscopic skills through a concise simulation curriculum.
    • Laparoscopic skills are retained for at least 6 weeks after training.
    • Skill decay becomes apparent by 11 weeks, indicating a need for refresher training and practice.
