Rescue using NOTES during endoscopic ultrasound-guided hepaticogastrostomy, after maldeployment of fully covered self-expandable metal stent.

A 56-year-old man was admitted to our hospital with obstructive jaundice caused by extrahepatic cholangiocarcinoma that developed from a congenital choledochal cyst ([Fig. 1]). Endoscopic retrograde cholangiopancreatography was hampered by ampullary effacement caused by malignant invasion. Endoscopic ultrasound (EUS)-guided hepaticogastrostomy was therefore attempted using an 8-cm fully covered self-expandable metal stent (FCSEMS) (Boston Scientific, Marlborough, Massachusetts, USA).
