Abstract Obstructive jaundice due to unresectable malignant hilar obstruction can be treated by deployment of bilateral uncovered selfexpandable metal stents (UCSEMSs), which enable longer stent patency to be obtained compared with multiple plastic stents [1–3]. However, re-intervention is needed if obstructive jaundice occurs after bilateral UCSEMS deployment. During re-intervention procedures, insertion of the stent delivery system across the mesh of a UCSEMS and into the bile duct can be challenging. A novel drill dilator has recently become available in Japan (Tornus ES; Asahi Intecc, Nagoya, Japan) ( Fig. 1) [4]. The tract is easily dilated using a clockwise rotation. We herein describe a successful reintervention using this device for a patient with occluded bilateral UCSEMSs.
