Effect of Continuous Motion Parameter Feedback on Laparoscopic Simulation Training: A Prospective Randomized...

Area of Science:

• Surgical Education
• Medical Simulation
• Laparoscopic Surgery Training

Background:

• Laparoscopic surgery requires specialized skills.
• Standardized training curricula are essential for surgical novices.
• Objective feedback can enhance skill acquisition.

Purpose of the Study:

• To evaluate the impact of motion parameter feedback on laparoscopic basic skill acquisition.
• To assess the effect of this feedback on skill retention over time.
• To compare a novel feedback system with traditional box training.

Main Methods:

• A prospective controlled trial involving surgical novices.
• Randomization into a regular box training group and a motion feedback (Hybrid) group.
• Standardized box tasks and virtual reality (VR) cholecystectomy simulations were used for training and assessment.
• Skill retention was evaluated after 6 weeks.

Main Results:

• Both groups showed significant improvement in laparoscopic skills.
• The Hybrid group demonstrated significant improvements in operation time, instrument path length, and movement count during VR simulations.
• Comparable skill retention was observed in both groups after 6 weeks.

Conclusions:

• Simulation-based training effectively develops basic laparoscopic skills.
• Motion parameter feedback significantly enhances skill acquisition and motion economy.
• Training systems incorporating motion feedback are valuable for improving surgical trainees' long-term performance.
