Endosonography-Guided Biliary Drainage with One-Step Placement of a Newly Developed Fully Covered Metal Stent Followed by Duodenal Stenting for Pancreatic Head Cancer
Figure 1
Endosonography-guided biliary drainage ((a) endosonography; (b) duodenoscopy; (c) fluoroscopy). Using a convex linear-array echoendoscope, puncture of the extrahepatic bile duct via the duodenal bulb was performed with a 19G needle (arrow) (a). A fully-covered metal stent (c, arrows) (covered ZEOSTENT), 6 cm in length and 1 cm in diameter, was placed via the puncture tract (b, c).
