Virtual liver resection systems offer 3D imaging and volumetric analysis for safer liver surgery. Future navigation systems aim to align preoperative plans with real-time surgery, enhancing standardization.

Area of Science:

  • Hepatobiliary Surgery
  • Medical Imaging
  • Computer-Assisted Surgery

Background:

  • Accurate evaluation of liver structures and functional remnant volume is crucial for safe liver surgery.
  • Conventional 2D imaging limits detailed pre-operative assessment of liver anatomy and function.

Purpose of the Study:

  • To explore the utility of virtual liver resection systems in pre-operative planning for liver surgery.
  • To identify challenges and future directions for computer-assisted liver surgery, particularly in real-time applications.

Main Methods:

  • Utilizing three-dimensional (3D) image-processing software for virtual liver resection.
  • Performing detailed volumetric analyses based on portal perfusion and venous drainage.
  • Investigating the capabilities of virtual systems beyond conventional 2D modalities.

Main Results:

  • Virtual liver resection systems provide 3D visualization of liver structures.
  • These systems enable detailed volumetric analysis and quantitative estimation of venous drainage.
  • They offer insights into liver anatomy not achievable with traditional methods.

Conclusions:

  • Virtual liver resection systems enhance pre-operative planning for liver surgery.
  • Real-time application of virtual hepatectomy faces challenges in aligning preoperative data with intraoperative conditions due to liver deformation.
  • Navigation systems are expected to improve the safety and standardization of liver surgery in the future.
