Summary
This study developed a virtual reality (VR) curriculum for laparoscopic camera navigation. The VR training demonstrated validity and improved skills, suggesting it’s a valuable tool for surgical trainees.
Area of Science:
- Surgical Education
- Medical Simulation
- Laparoscopic Surgery
Background:
- Camera handling and navigation are crucial for laparoscopic surgery, with less experienced team members often responsible for camera operation.
- Essential camera skills include orientation, horizon maintenance, zoom control, and lens clarity.
- Virtual reality (VR) simulation offers a potential method for developing these camera skills in novice surgeons.
Purpose of the Study:
- To develop and implement a novel virtual reality (VR)-based curriculum for laparoscopic camera navigation.
- To assess the construct and face validity of this VR curriculum in a trainee population.
- To determine if the curriculum can differentiate between varying levels of laparoscopic experience.
Main Methods:
- A proficiency-based curriculum was implemented on the LapSim VR simulator for 41 participants (medical students, residents, fellows, attendings).
- Participants were stratified into novice, intermediate, and advanced groups based on prior laparoscopic experience.
- The curriculum included modules on camera navigation, coordination, and target visualization, with metrics such as time, target misses, and drift analyzed.
Main Results:
- Significant differences were observed in the number of repetitions required to complete the curriculum across experience groups (novice, intermediate, advanced).
- The advanced group required fewer repetitions (11.7) compared to intermediate (21.2) and novice (41.8) groups (P < 0.05).
- Participants rated the training highly for improving camera skills, relevance to surgery, and overall validity, with high regard for graphics and realism.
Conclusions:
- The developed VR camera navigation curriculum demonstrates construct and face validity within the surgical trainee population.
- VR simulation for camera navigation is a potentially valuable tool for integration into surgical training programs.
- This curriculum can aid in developing essential camera handling skills for residents and medical students.
