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.
Core Tip: Ablate or not prior to stent insertion in patients with unresectable biliary cancer? The role of endo-biliary radiofrequency ablation before stent remains unclear regarding the overall survival and the prolongation of stent patency. Contrary results are probably attributed to differences in the studies' design, cancer extensiveness, patient performance status, and applied technique. Moreover, it has to be clarified whether percutaneous transhepatic cholangiodrainage overcomes endoscopic retrograde cholangiopancreatography as the method of choice for performing ablation, especially in more complicated cases.
