title: Tumor extension along percutaneous transhepatic biliary drainage tracts.
abstract: 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.
