Summary
Computer-assisted surgery (CAS) enhances liver resection accuracy by using 3D modeling and simulation. Novel techniques improve visualization and planning for safer hepatectomy and better surgical education.
Area of Science:
- Hepatobiliary Surgery
- Medical Imaging
- Surgical Simulation
Background:
- Accurate hepatectomy requires understanding complex liver anatomy and tumor location.
- Three-dimensional (3D) preoperative simulation for liver surgery is increasingly adopted in Japan.
- Computer-assisted surgery (CAS) has evolved for virtual hepatectomy planning.
Purpose of the Study:
- To review the history and advancements of virtual hepatectomy using CAS.
- To discuss the development and application of novel CAS techniques in liver surgery.
- To explore the future prospects of CAS in improving hepatectomy outcomes and surgical education.
Main Methods:
- Utilized SYNAPSE VINCENT system for 3D visualization and virtual resection since 2010.
- Developed a fusion imaging technique combining 3D CT and MRI for enhanced anatomical visualization.
- Created Liversim software for real-time liver deformation simulation and a hollow 3D-printed liver model.
Main Results:
- Fusion imaging effectively visualizes critical anatomical relationships in the hepatic hilum.
- Liversim and SYNAPSE VINCENT are being evaluated in a randomized control trial for preoperative planning.
- A novel hollow 3D-printed model reduces production cost and improves visibility for safer resection.
Conclusions:
- CAS, including 3D modeling and simulation, aids in planning and executing liver resections.
- Advanced CAS systems contribute to reliable hepatectomy and enhance surgical training.
- Novel fusion imaging and 3D printing technologies offer significant benefits for liver surgery.
