Abstract
An 80-year-old man was hospitalized for gallstone pancreatitis in our hospital and he underwent endoscopic sphincterotomy (EST). After EST, we tried to place a pancreatic stent (one-sided pigtail type) to prevent exacerbation of pancreatitis, but the stent migrated into the main pancreatic duct. The proximal edge of the stent was located in a side branch of the pancreatic duct, and we could not retrieve the stent in spite of using a balloon catheter and some forceps. On the third hospital day, we tried to retrieve the stent again. We guided the sheath (5Fr) of a basket catheter for removal of biliary stones (Memory Basket® Eight Wire) to the distal edge of the stent across the guidewire, and inserted only the wire of a snare for polypectomy (SensationTM Medium Stiff Wire) into the sheath. We opened the snare at the far side of the distal side of the stent, could catch the stent and could retrieve it successfully.
