A 53-year-old woman developed a pancreatic pseudocyst after undergoing treatment for severe gallstone pancreatitis. Because of the enlarged pancreatic pseudocyst and constricted main pancreatic duct (MPD), we placed a 7-Fr. 7-cm straight pancreatic stent in the MPD endoscopically, but the stent migrated to a branch duct at the pancreatic head. We could not retrieve the stent by using a basket and balloon catheter. We led a guidewire into the stent through a flap on the pancreatic tail end of the stent and then pushed the stent toward the pancreatic tail by using a pushing device. Consequently, the papillary end of the stent was replaced with the MPD, allowing us to retrieve the stent by using a stent retriever. Because surgical operations were reported to be necessary for similar cases, this endoscopic retrieval method may be useful to avoid surgical operations.
