Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Medical Imaging

Background:

  • Liver resection is the primary curative treatment for primary liver cancers, including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma.
  • Anatomical resection, targeting tumor-bearing segments, is vital for eradicating intrahepatic metastases in HCC, often spreading via portal venous systems.

Purpose of the Study:

  • To highlight the technical demands and essential elements of precise anatomical liver resection.
  • To discuss the integration of advanced imaging and computer technologies in preoperative planning, intraoperative navigation, and postoperative evaluation of anatomical liver resections.

Main Methods:

  • Review of current techniques in anatomical liver resection, including segmentectomy and subsegmentectomy.
  • Discussion of the role of dye-injection methods and intraoperative ultrasonography.
  • Exploration of advancements in imaging studies and computer technologies for surgical planning and navigation.

Main Results:

  • Anatomical liver resection is technically demanding, requiring significant surgical experience and deep knowledge of liver anatomy.
  • New technologies facilitate preoperative design, intraoperative navigation, and postoperative assessment of anatomical liver resections.
  • Despite technological advancements, the core surgical procedure remains dependent on surgeon skill and meticulous technique.

Conclusions:

  • Precise anatomical liver resection is essential for effective treatment of liver cancer.
  • While technology enhances the process, skilled surgical execution, detailed anatomical understanding, and intraoperative tools like ultrasonography are indispensable.
  • Future advancements may further refine these procedures, but human expertise remains central.
