摘　　要：Introduction 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 ordinarymethods 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.
