Area of Science:

  • Surgical Education
  • Minimally-Invasive Surgery
  • Laparoscopic Techniques

Background:

  • Advanced surgical training increasingly utilizes minimally-invasive techniques.
  • Developing proficiency in laparoscopic surgery requires specialized training models.
  • Rat models offer a reproducible platform for surgical skills development.

Purpose of the Study:

  • To assess the efficacy of a structured training program for advanced minimally-invasive surgery using rat models.
  • To evaluate the improvement in laparoscopic surgical skills among surgical residents.
  • To determine the reproducibility and effectiveness of rat models in surgical training.

Main Methods:

  • Ten surgical residents with limited laparoscopic experience underwent a two-day training course.

  • Training progressed from a rubber model to increasingly complex open and closed rat models.
  • Surgical skills were evaluated using five defined tasks in a simulation trainer before and after the intervention.
  • A control group of eight residents with similar experience was tested after a two-day interval without training.

    • Main Results:

    • All participants in the training program demonstrated significant improvement across all five assessed surgical tasks (p < 0.05).
    • The control group showed significant improvement in only one task after repetition, highlighting the training's impact.
    • Trained residents consistently outperformed controls, showing significant skill enhancement before and after the training period (p < 0.05).

    Conclusions:

    • Surgical training utilizing the rat model is highly effective for developing advanced minimally-invasive surgical skills.
    • The rat model provides a reproducible platform for enhancing laparoscopic proficiency, particularly in bimanual tissue handling, knot tying, and microsurgical suturing.
    • This training approach offers a valuable method for improving surgical residents' competency in minimally-invasive procedures.
