Area of Science:

  • Hepatobiliary surgery
  • Medical imaging
  • Surgical oncology

Background:

  • Hepatobiliary surgery presents significant technical challenges due to intricate intrahepatic and perihilar anatomy.
  • Complex anatomical variations in the liver require advanced visualization for safe surgical planning.

Purpose of the Study:

  • To highlight the critical role of three-dimensional (3D) imaging in precise liver surgery.
  • To demonstrate how 3D imaging aids in understanding complex surgical anatomy and improving surgical outcomes.

Main Methods:

  • Utilizing three-dimensional imaging techniques for detailed visualization of liver anatomy.
  • Employing surgical simulation based on 3D imaging for preoperative planning.
  • Analyzing the depiction of tumors, vascular structures (portal vein, hepatic artery, hepatic vein), and biliary systems.
Keywords:

Main Results:

  • 3D images distinctly show tumor location, vascular variations, and biliary pathways from all angles.
  • Preoperative identification of critical vessels is facilitated through 3D imaging and surgical simulation.
  • Measurements of surgical margins and future remnant liver volume are accurately provided.

Conclusions:

  • Three-dimensional imaging significantly improves the resectability and safety of complex hepatobiliary procedures.
  • Applications include hilar cholangiocarcinoma, central liver tumors, hepatolithiasis, and living donor liver transplantation.
  • 3D visualization enhances surgeons' comprehension of complex anatomy and two-dimensional imaging data.
