Transferability of laparoscopic skills using the virtual reality simulator

Area of Science:

• Surgical Education
• Medical Simulation
• Laparoscopic Surgery

Background:

• Skill transfer in surgical education is not well understood.
• Assessing skill transfer between laparoscopic procedures is crucial for training.
• Virtual reality simulators offer a platform for studying skill transfer.

Purpose of the Study:

• To assess the transferability of surgical skills between laparoscopic appendectomy and cholecystectomy.
• To evaluate the effectiveness of virtual reality simulation in surgical skill transfer for novices.
• To analyze motor and cognitive skill transfer in simulated laparoscopic surgery.

Main Methods:

• A randomized study involving 44 surgical novices.
• Proficiency-based basic training on selected simulated laparoscopic tasks.
• Group 1 trained on appendectomy then cholecystectomy; Group 2 trained directly on cholecystectomy.
• Analysis of time, safety, and economy parameters during simulated cholecystectomy.

Main Results:

• No significant demographic or prior gaming experience differences between groups.
• Group 1 (appendectomy first) showed significantly fewer movements and shorter path length during cholecystectomy.
• No significant differences in time or safety parameters were observed between groups.

Conclusions:

• Positive transfer of motor skills observed between appendectomy and cholecystectomy simulation.
• Cognitive skill transfer was limited, suggesting a need for procedure-specific training.
• Separate curricula and mentoring may enhance effective skill transfer in surgical trainees.
