Figure 1 Cholangiocarcinoma stricture and radiofrequency ablation. A: Tumor ingrowth into uncovered metallic stent (placed for distal cholangiocarcinoma), allowing passage of guidewire but no other equipment; B: Treated with Habib radiofrequency ablation probe, to achieve patency of stent, which allowed successful biliary drainage.
