Percutaneous transhepatic cholangiography. Problems in interpretation.

R D Kittredge, J W Baer

    The American Journal of Roentgenology, Radium Therapy, and Nuclear Medicine
    |September 1, 1975
    PubMed
    Summary

    Percutaneous transhepatic cholangiography (PTC) is crucial for diagnosing jaundice, differentiating liver disease from biliary obstruction. This imaging technique prevents unnecessary surgeries and guides treatment for jaundiced patients.

    Area of Science:

    • Hepatology
    • Diagnostic Imaging
    • Gastroenterology

    Background:

    • Jaundice diagnosis is challenging, often requiring advanced imaging beyond standard gallbladder series or intravenous cholangiography.
    • Clinical and laboratory evaluations may not reliably distinguish between primary liver parenchymal disease and biliary tract obstruction.

    Observation:

    • Percutaneous transhepatic cholangiography (PTC) effectively visualizes the biliary system when successfully performed.
    • Careful technique is essential to avoid misinterpretation, such as incomplete aspiration of bile or peripheral biliary system entry.

    Findings:

    • PTC accurately determines if jaundice stems from liver disease or biliary obstruction.
    • Selective visceral angiography aids in identifying the etiology of biliary obstruction.

    Implications:

    • PTC prevents unnecessary exploratory surgery in patients with primary liver parenchymal disease.
    • It provides critical information for planning surgical intervention in cases of biliary tract obstruction.
