This study reveals significant variability in left hepatic duct anatomy, crucial for understanding biliary interventional procedures. Anatomical variations impact surgical planning and patient outcomes in liver interventions.

Area of Science:

  • Hepatobiliary Anatomy
  • Surgical Anatomy
  • Interventional Radiology

Background:

  • Biliary interventional procedures require precise anatomical knowledge.
  • Variability in biliary ductal anatomy can complicate procedures.
  • Understanding the left hepatic duct's anatomy is critical for liver interventions.

Purpose of the Study:

  • To investigate the anatomical variations of the left hepatic duct.
  • To correlate anatomical findings with clinical experience in biliary procedures.
  • To highlight the implications of biliary anatomy variability.

Main Methods:

  • Review of 10-year experience with 838 biliary interventional procedures.
  • Dissection and fixation of 15 normal human livers obtained at autopsy.

  • Detailed anatomical analysis of the left hepatic duct and associated structures.

    • Main Results:

    • Fifty-five percent of patients exhibited a single left hepatic duct formed intrahepatically.
    • The left duct joined ducts from segments I and IV centrally to the falciform ligament.
    • Variations in ductal drainage and proximity to the left portal vein were observed.

    Conclusions:

    • Significant anatomical variability of the left hepatic duct exists.
    • This variability has implications for biliary interventional procedures.
    • Awareness of anatomical variations is essential for safe and effective liver interventions.
