Video Context Improves Performance in Identifying Operative Planes on Static Surgical Images

Area of Science:

• Surgical Education
• Medical Simulation
• Anatomical Dissection

Background:

• Accurate identification of surgical tissue planes is critical in the operating room.
• Realistic dynamic models may enhance surgical skill acquisition more than static images.
• Surgeons' experience levels influence the precision and accuracy of tissue plane identification.

Purpose of the Study:

• To assess the impact of adding video prequels to still images on surgical tissue plane identification.
• To evaluate the role of surgeon experience in the effectiveness of video-enhanced training.
• To determine if dynamic visual aids improve precision and accuracy in surgical simulation.

Main Methods:

• Prospective observational study with 15 surgeons (consultant, senior, junior groups).
• Surgeons identified tissue planes on images before and after viewing a 10-second video prequel.
• Validated metric (modified Hausdorff distance) measured precision and accuracy against expert-defined planes.

Main Results:

• Consultant surgeons demonstrated the highest precision, with significant differences between all experience groups.
• Overall accuracy showed a significant interaction between viewing time (pre/post-video) and surgeon experience level.
• Junior surgeons, while less accurate initially, showed significant improvement in precision after watching videos.

Conclusions:

• Video context enhances the ability of junior trainees to identify surgical tissue planes.
• Realistic, dynamic simulation models are recommended for surgical training programs.
• Training programs should consider experience-based differences in precision and incorporate adaptive learning tools.
