[Experience with percutaneous transhepatic cholangiography]

R Seidel, D Hölzel, G Singer

    Summary

    Percutaneous transhepatic cholangiography (PTC) effectively visualizes bile ducts in 87.6% of cases for diagnosing biliary obstruction. However, this method is not recommended for anicteric patients due to lower success rates.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Hepatology

    Context:

    • Percutaneous transhepatic cholangiography (PTC) is an imaging technique used to visualize the biliary tree.
    • Evaluating the diagnostic accuracy and clinical utility of PTC is crucial for managing biliary obstruction.
    • Comparison with endoscopic retrograde cholangiography (ERC) aids in selecting the optimal imaging modality.

    Purpose:

    • To report experiences and evaluate the technical performance of percutaneous transhepatic cholangiography.
    • To assess the diagnostic accuracy of PTC in differentiating biliary obstruction syndromes.
    • To determine the indications and contraindications for PTC, particularly in relation to patient characteristics like jaundice.

    Summary:

    • 114 PTC examinations were performed, successfully visualizing bile ducts in 87.6% of patients.
    • PTC results confirmed the diagnosis in 85% of cases, altered it in 5%, and required adjustment based on surgical outcomes in 10%.
    • Puncture failure occurred in 12.4% of cases, notably including 10 anicteric patients, suggesting limited utility in non-jaundiced individuals.

    Impact:

    • PTC, utilizing a reflux technique, demonstrates high impact and good evidence for morphological differentiation of obstruction syndromes.
    • The study suggests PTC is not indicated for anicteric patients.
    • PTC can be performed with readily available equipment, highlighting its accessibility.
