Summary
This study introduces a 3D liver resection planning system that quantifies surgical proposals based on patient-specific anatomy. It aids in predicting post-operative liver function for improved patient selection and surgical outcomes.
Area of Science:
- Hepatobiliary surgery
- Surgical planning
- Medical imaging
Background:
- Liver tumor operability depends on 3D relationship to vascular trees defining liver segments.
- Anatomic variability and tumor distortion complicate precise surgical planning.
- Current systems lack intra-operative tracking, limiting integration with navigation.
Purpose of the Study:
- To develop a 3D operation planning system for quantifiable liver resection proposals.
- To enable precise patient selection based on predicted post-operative liver function.
- To integrate quantitative resection planning with visualization tools.
Main Methods:
- Quantification of organ structures and resection volumes using absolute and relative values.
- Definition of resection planes based on security margins and intrahepatic vascular trees.
- Visualization of data through 3D movies and quantitative reports.
Main Results:
- A novel 3D operation planning system provides quantifiable liver resection proposals.
- The system utilizes individualized patient anatomy for tailored surgical plans.
- Results are presented via visualized digital movies and detailed quantitative reports.
Conclusions:
- The developed system offers a quantifiable approach to liver resection planning.
- It enhances patient selection by predicting post-operative liver function.
- The system visualizes surgical proposals, aiding surgeons in complex cases.
