Biliary stricture is a less common complication after hepatic radiofrequency ablation (RFA) [1, 2]. Patients with biliary stricture often present with recurrent jaundice, fever or chills, and require endoscopic or percutaneous biliary drainage, and in some cases recanalization of the biliary tract [3]. Establishing guide-wire passage through the stricture is essential for biliary recanalization. However, in some cases of complete biliary obstruction, a more aggressive technique is needed when ordinary methods fail to establish. Herein, we report a novel technique of extraluminal recanalization for biliary strictures using a Chiba biopsy needle, which is similar to sharp endovascular recanalization.
