Area of Science:

  • Robotic surgery
  • Surgical simulation
  • Medical education

Background:

  • Objective assessment of robotic surgical proficiency is crucial for training.
  • Virtual simulation offers a standardized method for evaluating surgical skills.
  • This pilot study explored the utility of a specific virtual module for this purpose.

Purpose of the Study:

  • To evaluate a single virtual-simulation suturing module as an objective measure of robotic system functional use.
  • To establish construct validity by comparing scores across different skill levels.
  • To inform the design of objective, adjunctive tests for surgical proctors.

Main Methods:

  • 38 subjects with varying robotic surgery experience performed two "Tubes" module attempts on the Da Vinci® Surgical Skills Simulator™.
  • The overall MScore was analyzed for correlation with prior robotic case numbers and differences between novice and experienced surgeons.
  • Paired t-tests and logistic regression analyzed nine individual metrics.

Main Results:

  • The MScore correlated with the number of prior robotic cases (R(2)=0.465; p=0.003).
  • Significant differences in MScore were observed between novice and experienced surgeons on both the first (44.7 vs. 63.9; p=0.005) and second attempts (56.0 vs. 69.9; p=0.037).
  • Median completion time for both tasks was under 10 minutes.

Conclusions:

  • A single virtual simulator exercise provides objective data on robotic surgical system proficiency.
  • This method can effectively differentiate between surgeons of varying experience levels.
  • Virtual simulation serves as a valuable tool for assessing and validating robotic surgical skills.
