New surgeons and medical students benefit most from laparoscopic skills training. Practicing each task 30-35 times is recommended for maximal improvement in surgical skills.

Area of Science:

  • Medical Education
  • Surgical Skills Training
  • Laparoscopic Surgery

Background:

  • Laparoscopic surgery requires specialized psychomotor skills.
  • A validated laparoscopic skills curriculum exists.
  • Quantifying the learning curve is essential for curriculum optimization.

Purpose of the Study:

  • To quantify the learning curve associated with a validated laparoscopic skills curriculum.
  • To assess skill acquisition across different levels of surgical training.

Main Methods:

  • Second-year medical students (MS2) and surgical residents (PGY2, PGY3) participated.
  • A curriculum involving five video-trainer tasks was used.
  • Subjects underwent baseline testing, 10 days of training, and final testing, with scores based on completion time.

Main Results:

  • No significant differences in baseline scores were observed between groups.
  • Final scores were significantly better for MS2s compared to PGY3s.
  • Adjusted improvement was greatest for MS2s, followed by PGY2s, then PGY3s, indicating steeper learning curves for less experienced trainees. A 90th percentile score was predicted at 32 repetitions.

Conclusions:

  • Inexperienced trainees, such as medical students, show the most significant gains from laparoscopic skills training.
  • To achieve maximal benefit from the curriculum, practicing each task approximately 30-35 times is recommended.
  • This data can inform curriculum design and trainee progression in laparoscopic surgery.
