Figure 3: (a) Cholangiography showed obstructions involved the common bile and hepatic duct but did not extend into the confluence. (b) Intraductal radiofrequency ablation was performed with a percutaneous radiofrequency catheter using a 0.035 inch guidewire. (c) Cholangiography confirmed immediate stricture improvement was achieved after radiofrequency ablation. (d) A self-expanding metallic stent was inserted after the ablation. Cholangiography showed that the obstruction was relieved
