Summary
The Virtual Basic Laparoscopic Surgical Trainer (VBLaST) shows promise for surgical training, despite lower initial performance compared to the Fundamentals of Laparoscopic Skills (FLS) trainer. Surgeons showed faster learning on VBLaST, indicating potential for virtual reality in skill development.
Area of Science:
- Medical Simulation
- Surgical Education
- Virtual Reality Technology
Background:
- Laparoscopic surgery demands advanced surgeon training beyond traditional open procedures.
- The Virtual Basic Laparoscopic Surgical Trainer (VBLaST) is a virtual reality (VR) counterpart to the Fundamentals of Laparoscopic Skills (FLS) trainer.
- Assessing VR and haptic technology in surgical simulation is crucial for effective training.
Purpose of the Study:
- To evaluate the haptic and VR technology of the VBLaST using a virtual peg transfer task.
- To compare surgeon performance and subjective preferences between the VBLaST and the FLS trainer.
- To identify the added value of VR and haptic feedback in surgical skill acquisition.
Main Methods:
- Twenty-one surgical trainees (residents, fellows, attendings) performed a peg-transfer task on both FLS and VBLaST simulators.
- Each participant completed 10 trials per simulator to assess objective performance.
- Subjective preferences regarding simulator technology were collected.
Main Results:
- Surgeons performed significantly better on the FLS compared to the VBLaST.
- A significant learning effect was observed on both simulators, with faster improvement noted on the VBLaST.
- Despite performance differences, 81% of participants preferred the FLS, citing VR novelty and haptic interface limitations.
Conclusions:
- While surgeons preferred the physical FLS trainer, objective performance data suggests VR and haptic technology offer value in surgical training.
- The VBLaST demonstrated accelerated learning, indicating potential for future surgical simulation development.
- Further research on more complex tasks like suturing and knot-tying is recommended to fully realize VR/haptic benefits.
