Core tip: The majority of patients with hilar cholangiocarcinoma present in advanced stages and are candidates for palliation only. The techniques of palliation, primarily at endoscopy or by percutaneous techniques, are evolving as better stents become available. Alternate techniques, such as endosonography-guided procedures, are also becoming popular. Photodynamic therapy and radio-frequency ablation are also used to improve the results of biliary stents. This review article provides a consolidated picture of the present knowledge in this field based on recent data.
