Brief Summary

Abstract: Minimally invasive techniques are now ubiquitous in the management of surgical disease. Competence in laparoscopy requires specialized training and practice. With the decrease of resident work hours, training programs need to explore and adopt efficient strategies to teach and evaluate laparoscopic skills. For economic, ethical, and legal considerations, the operating room may no longer be the ideal environment for teaching these basic technical skills. There appears to be a role for simulation in response to this need. The transfer of laparoscopic skills learned in a simulated environment to the operating room has showed mixed results. Overall, it seems that surgical skills training outside the operating room is beneficial, but the best method(s) of designing, implementing and evaluating such skills curriculums have yet to be identified. The laparoscopic totally extraperitoneal (TEP) inguinal hernia repair is an example of a procedure that is associated with a steep learning curve and requires mastery of basic laparoscopic skills. In addition, an increased recurrence and complication rates in the early learning curve of this procedure, underscores the importance of adequate training. The current practice of teaching the TEP repair in the operating room under an apprenticeship-based model is associated with increased operative time and costs. We propose that the training of surgical trainees outside the operating room with a structured, mastery oriented simulation-based curriculum will help reduce the learning curve of the TEP repair, improve operative performance, and decrease operative time and costs.

Outcome Measures

Primary Outcomes (1)

  • Participation-Corrected Operative Time

    Operative time was recorded with a standard stopwatch, began at the start of the operative case and ended when procedure was terminated. We realized that the operative time for poorly performing trainees could be faster than the time for more skilled trainees because the supervising surgeon would perform a greater proportion of the procedure. We calculated participation-corrected time as raw total time + the time of staff involvement: time\_corrected = time\_raw + (1-participation) x time\_raw.

    at first TEP procedure post-randomization; Due to surgical scheduling variability this can be anytime from 1 to 2 days following randomization to a week or two

Secondary Outcomes (2)

  • Operative Performance

    at first TEP procedure post-randomization; due to surgical scheduling variability this can be anytime from 1 to 2 days following randomization to a week or two

  • Number of Hernia Repair Subjects With Post-Operative Urinary Retention

    at first TEP procedure post-randomization, subjects were followed for the duration of hospital stay, an average of 1 night

Study Arms (2)
