EUS-BD procedures. (a) The extrahepatic bile duct was visualized from the duodenal bulb using a curved linear array echoendoscope and punctured using a 19-G fine-aspiration needle. (b) The biliary tract was opacified with contrast medium. (c) A fully covered metallic stent was deployed through the choledochoduodenal fistula. Red arrows show the waist of the stent induced by the choledochal and duodenal walls. (d) Endoscopic view of the deployed stent observed from the pylorus.
