This study shows that simulator training for laparoscopic suturing improves surgical residents' operative performance. This performance-based curriculum effectively transfers skills to real surgical procedures.

Area of Science:

  • Surgical Education
  • Minimally Invasive Surgery
  • Medical Simulation

Background:

  • Developing effective laparoscopic suturing skills is crucial for surgical residents.
  • Current training methods may not adequately prepare residents for complex procedures.
  • A need exists for standardized, performance-based curricula in surgical simulation.

Purpose of the Study:

  • To develop a performance-based laparoscopic suturing curriculum utilizing simulators.
  • To evaluate the effectiveness and skill transferability of this novel curriculum.

Main Methods:

  • A randomized controlled trial enrolled 17 surgical residents (PGY1-5) with minimal laparoscopic suturing experience.
  • Residents were pretested on a porcine model, then trained using a videotrainer simulator to an expert-defined proficiency level.

  • A control group received no simulator training; both groups were posttested on the porcine model.

    • Main Results:

    • The trained group achieved simulator proficiency in a mean of 151 minutes over 37 attempts.
    • Both groups improved from baseline, but the trained group showed significantly better posttest scores (389 vs. 217, p < 0.001).
    • Results confirm the curriculum's effectiveness in enhancing operative performance.

    Conclusions:

    • Training to a predetermined expert level on a simulator model effectively transfers skills to operative performance.
    • Performance-based curricula using simulators should be further developed and implemented.
    • This approach ensures surgical resident proficiency in laparoscopic suturing.
