- Abstract
- Malignant hilar biliary obstruction (MHO), an aggressive perihilar biliary obstruction caused by cholangiocarcinoma, gallbladder can-cer, or other metastatic malignancies, has a poor prognosis. Surgical resection is the only curative treatment for biliary malignancies. However, the majority of patients with MHO cannot undergo surgery on presentation because of an advanced inoperable state or a poor performance state due to old age or comorbid diseases. Therefore, palliative biliary drainage is mandatory to improve symptomat-ic jaundice and the quality of life. Among the drainage methods, endoscopic biliary drainage is the current standard for palliation of unresectable advanced MHO. In addition, combined with endoscopic drainage, additional local ablation therapies, such as photody-namic therapy or radiofrequency ablation (RFA), have been introduced to prolong stent patency and survival. Currently, RFA is com-monly used as palliative therapy, even for advanced MHO. This literature review summarizes recent studies on RFA for advanced MHO.
