Area of Science:

  • Medical Education
  • Surgical Skills Training
  • Minimally Invasive Surgery

Background:

  • Developing efficient surgical hand skills is crucial for procedures like inguinal hernia repair.
  • Traditional training methods may not fully optimize the acquisition of complex surgical techniques.
  • Innovative teaching strategies are needed to enhance surgical proficiency.

Purpose of the Study:

  • To evaluate the impact of expert cognitive modeling, auditory elaboration, and split-screen video analysis on surgical residents' performance.
  • To assess the effect of these techniques on hand movements during inguinal hernia repair using the McVay technique.
  • To determine the efficacy of a novel teaching approach for surgical skill acquisition.

Main Methods:

  • A pretest-posttest control group design was employed with six surgical residents.

  • Residents performed an inguinal hernia repair using the McVay technique on cadavers.
  • The experimental group received expert cognitive modeling, auditory elaboration, and split-screen analysis post-pretest.

    • Main Results:

    • The experimental group demonstrated significant improvements in surgical instrument control and manipulation.
    • Shorter operation times were observed in the group that received the enhanced training.
    • More purposeful and precise surgical movements were exhibited by the experimental group.

    Conclusions:

    • The combined teaching intervention, including cognitive modeling and auditory elaboration, effectively enhanced learning of the McVay technique.
    • Mindfulness learning principles appear to be beneficial for mastering surgical procedures.
    • This approach shows promise for improving surgical education and patient outcomes.
