Pilot study of new training model for laparoscopic surgery.

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• Medical Simulation

Background:

• Assessing laparoscopic surgical skills is crucial for trainee development.
• Objective evaluation methods are needed to complement self-assessment.
• Novel simulation models offer potential for skill assessment.

Purpose of the Study:

• To determine if a laparoscopic trainer exercise reliably measures prior laparoscopic experience.
• To validate a new assessment tool for surgical trainees' laparoscopic proficiency.

Main Methods:

• Surgical trainees completed a baseline skills questionnaire and an exercise on a new laparoscopic trainer.
• Nine subjects with varied experience levels participated.
• Correlation analysis was used to compare exercise scores with self-assessed experience and training received.

Main Results:

• Higher self-assessment scores correlated with lower (better) exercise scores (P=0.003).
• Exercise scores were negatively correlated with training modalities (P=0.007) and overall laparoscopic experience (P=0.027).
• The assessment effectively differentiated between trainees with differing levels of laparoscopic experience.

Conclusions:

• The laparoscopic trainer assessment is sensitive and specific for evaluating surgical skills.
• This novel model can reliably gauge laparoscopic proficiency in trainees.
• The scoring system demonstrates validity in measuring relevant surgical skills.
