Implication

Comparative study demonstrates superior virtual reality suturing efficiency in experienced surgeons versus novices, indicating strong utility for surgical skills assessment and training.

Key Points

To evaluate an interactive virtual reality surgical simulator with force feedback for measuring and training suturing technique across varying levels of clinical experience.
Evaluated 8 experienced vascular surgeons and 12 medical students performing virtual reality suturing tasks across three test conditions: dominant hand, nondominant hand, and a 3-dimensional needle guide.
Tracked eight objective performance parameters, including total tissue damage, needle puncture accuracy, peak tearing force, completion time, angular error, and tool tip distance.
Surgeons demonstrated significantly superior performance compared to medical students in total tissue damage, task completion time, and total tool tip distance across all three test conditions (p <= 0.05), as well as overall error during the dominant-hand condition.
Medical students achieved significant performance gains in 6 of 7 feedback parameters during training, while surgeons improved significantly in 4 of 7 parameters, though group differences in improvement rate were not statistically significant.
