This study introduces Liversim, a novel 3D virtual hepatectomy simulation software. Liversim enables real-time liver deformation visualization, proving useful for safe hepatectomies and surgical education.
Area of Science:
- Medical Simulation
- Surgical Technology
- Hepatobiliary Surgery
Background:
- Virtual hepatectomy aids surgical planning.
- Real-time simulation of liver deformation is crucial for accurate hepatectomy.
- Existing software may lack advanced visualization capabilities.
Purpose of the Study:
- To develop and evaluate Liversim, a novel 3D virtual hepatectomy simulation software.
- To visualize real-time liver deformation during virtual hepatectomy.
- To assess Liversim's utility in surgical education and planning.
Main Methods:
- Development of Liversim software with functions for 3D model viewing, manipulation, and virtual incision.
- Comparison of perioperative outcomes between Liversim and SYNAPSE VINCENT in virtual hepatectomies.
- Evaluation of Liversim by medical students and surgical residents via questionnaires.
Main Results:
- No significant discrepancies were observed between Liversim simulations and actual hepatectomies.
- No significant differences in operating time, intraoperative bleeding, or postoperative stay between Liversim and SYNAPSE VINCENT.
- Liversim was not clinically inferior to SYNAPSE VINCENT, with users reporting realistic image fidelity.
Conclusions:
- Liversim provides a valuable tool for virtual hepatectomy simulation.
- The software facilitates the safe performance of hepatectomies through real-time deformation visualization.
- Liversim serves as an effective aid for surgical education and training in hepatectomy.
