Fig. 9. Stent occlusion after endoscopic ultrasonography-guided hepaticogastrostomy for pancreatic cancer. (A) The endoscopic cholangiogram shows stent occlusion caused by mucosal hyperplasia. However, the stent delivery system could not pass the stricture via the endoscopic route. (B, C) A guidewire was inserted from the right anterior duct into the stent of hepaticogastrostomy route via the percutaneous biliary drainage route and the additional stent (8-mm diameter, 40-mm length, Zilver stent; COOK Medical) was placed at the stricture point in stent-in-stent.
