Tumor extension along percutaneous transhepatic biliary drainage tracts.
Percutaneous Transhepatic Biliary Catheterization is commonly employed in the diagnosis and management of obstructive jaundice associated with malignant lesions. Tumor manipulation as an effort to obtain a histological diagnosis or to establish short or long-term internal-external biliary drainage is liable to disseminate the malignancy along the catheter tract. Two cases of malignant seeding of the catheter tract after biliary drainage have been observed.
