Interventional radiological treatment of malignant biliary obstruction.
Percutaneous transhepatic procedures have gained a strong position in the diagnosis and treatment of malignant biliary obstruction. Diagnostic cholangiography can easily be converted into therapeutic drainage, which is often the first step towards further diagnostic work-up (biopsy, percutaneous cholangioscopy) and tumour ablation and/or intraductal irradiation. Plastic endoprostheses and balloon- or self-expandable metallic stents are the therapeutic alternatives to achieve permanent internal drainage of bile.
