Abstract
Biliary cancer is a highly aggressive disease that is typically diagnosed at advanced stages when surgical removal is no longer an option. In these cases, palliative care and mechanical widening of the blocked biliary system are preferred. The insertion of a stent is often necessary to prevent the recurrence of blockages caused by cancer progression. Prior to stent placement, endo-biliary radiofrequency ablation (EB-RFA) appears to result in longer-lasting stent effectiveness without increasing the risk of severe complications. However, its impact on overall survival is not yet clear. Additionally, while endoscopic retrograde cholangiopancreatography is the most common method for performing EB-RFA, percutaneous transhepatic cholangiodrainage seems to be a safe and potentially more efficient alternative, particularly for long, angulated, or significantly narrowed bile ducts.
