Core Tip

Core Tip: Endoscopic radiofrequency ablation offers endoscopists a reasonable palliative method by which to treat patients with unresectable cholangiocarcinoma that results in longer survival as compared to biliary stenting alone, percutaneous radiofrequency ablation, with biliary stenting, and photodynamic therapy with biliary stenting.
