This study introduces a 3D virtual operation planning system for liver tumors. It aids in patient selection and precise surgical planning by quantifying liver volumes and predicting post-operative function.

Area of Science:

  • Hepatobiliary surgery
  • Medical imaging
  • Surgical planning

Background:

  • Liver tumor resectability is complex, influenced by 3D vascular anatomy and tissue volumes.
  • Anatomic variations and tumor-induced distortions complicate precise surgical planning.

Purpose of the Study:

  • To develop and validate a computer-based 3D virtual operation planning system for liver tumor surgery.
  • To enable precise prediction of post-operative liver function for patient selection.

Main Methods:

  • Development of a computer-based 3D virtual operation planning system.
  • Quantification of absolute and relative volumes of liver structures and resected parenchyma.
  • Visualization of tumor, liver, and vessel tree relationships in 3D.

Main Results:

  • The system provides quantifiable liver resection proposals based on individualized anatomy.
  • It enables exact prediction of post-operative liver function.
  • Results are presented through 3D movies, interactive visualizations, and quantitative reports.

Conclusions:

  • The developed 3D virtual operation planning system is ready for routine clinical use.
  • It significantly improves pre-operative planning for liver tumor resections.
  • The system facilitates better patient selection and surgical outcome prediction.
