    This study classifies hepatolithiasis based on cholangiographic features observed via percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiography (ERC). Findings suggest a correlation between these classifications and clinical presentations.

    Area of Science:

    • Hepatobiliary imaging
    • Gastroenterology
    • Radiology

    Background:

    • Hepatolithiasis, characterized by intrahepatic bile duct stones, presents diagnostic challenges.
    • Accurate classification is crucial for understanding disease progression and treatment strategies.

    Purpose of the Study:

    • To describe the cholangiographic features of hepatolithiasis.
    • To propose a classification system for hepatolithiasis based on imaging findings.
    • To investigate the correlation between cholangiographic patterns and clinical features.

    Main Methods:

    • Retrospective analysis of cholangiographic data from 150 patients.
    • Utilized percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiography (ERC).
    • Categorized findings into primary and secondary hepatolithiasis, with further subdivision of primary cases.

    Main Results:

    • Described distinct cholangiographic features for hepatolithiasis.
    • Proposed a classification: primary (major intrahepatic bile duct type, peripheral intrahepatic bile duct type) and secondary hepatolithiasis.
    • Identified correlations between the proposed cholangiographic classifications and patient clinical features.

    Conclusions:

    • Cholangiography via PTC and ERC provides valuable insights into hepatolithiasis.
    • A proposed classification system aids in categorizing hepatolithiasis based on imaging.
    • The cholangiographic classification correlates with clinical characteristics, aiding in patient management.
