Successful retrieval of a fractured migrated pancreatic stent using an endoscopic tapered sheath for severe pancreatic duct stenosis.

Endoscopic pancreatic stenting is a well-accepted treatment for symptomatic pancreatic duct stenosis [1] [2]; however, during stent removal, stent fracture can occur owing to severe pancreatic duct stenosis [3] [4]. In such cases, removal of the migrated fractured stents is difficult using conventional devices, which are unable to pass the site of the severe stenosis over the guidewire. Therefore, we used an endoscopic tapered sheath (EndoSheather; Piolax Inc., Kanagawa, Japan), a device that simultaneously enables both stenosis breakthrough and retrieval of the migrated stent (up to a diameter of 1.9 mm) through the indwelling outer sheath ([Fig. 1]).
