Objective performance indicators (OPIs) can differentiate surgeon skill levels during robotic right colectomy. Expert and intermediate surgeons show distinct movement patterns compared to novices, enabling objective skill assessment.

Area of Science:

  • Robotic Surgery
  • Surgical Skill Assessment
  • Machine Learning in Medicine

Background:

  • Traditional surgeon assessment is subjective and lacks scalability.
  • Objective Performance Indicators (OPIs) leverage machine learning for quantifiable metrics during robotic surgery.
  • OPIs provide objective insights into surgeon movements and robotic arm kinematics.

Purpose of the Study:

  • To identify Objective Performance Indicators (OPIs) that differentiate surgeon skill levels.
  • To compare OPIs across expert (EX), intermediate (IM), and novice (NV) surgeons during robotic right colectomy (RRC).

Main Methods:

  • 25 robotic right colectomies were analyzed, with 461 surgical steps annotated from endoscopic videos.
  • OPIs were compared among two EX, two IM, and eight NV surgeons.

  • Analysis focused on key surgical phases: mesenteric dissection, vascular pedicle ligation, and bowel mobilization/preparation.

    • Main Results:

    • Expert and intermediate surgeons exhibited significantly higher velocity, acceleration, and jerk for multiple robotic arms compared to novices.
    • Intermediate surgeons showed increased arm swaps, master clutch use, and camera-related metrics.
    • Both expert and intermediate surgeons demonstrated longer path lengths and greater arm velocities/accelerations than novices.

    Conclusions:

    • Specific OPIs effectively discriminate between expert, intermediate, and novice surgeons during RRC.
    • This study demonstrates the feasibility of using OPIs for objective and scalable surgeon skill classification in RRC.
