Abstract

<p>Case 1 was a 61-year-old woman who underwent endoscopic retrograde cholangiopancreatography (ERCP) for the purpose of suspected pancreaticobiliary maljunction. Case 2 was a 77-year-old man who underwent ERCP for examination of left intrahepatic bile duct dilation. Both patients had undergone preventive pancreatic stent placement for post-ERCP pancreatitis. In Case 1, the stent migrated while placing the pancreatic stent. In Case 2, the stent spontaneously migrated after stent placement. Both stents were retrieved by the small-diameter biopsy forceps that dwelled in the pusher catheter of the pre-loaded biliary stent. There are many cases in which it is difficult to retrieve a migrated pancreatic stent because of poor operability of the device in the main pancreatic duct. We report two cases in which the migrated pancreatic stent was effectively retrieved by a small-diameter biopsy forceps that dwelled in the pusher catheter.</p>
