title: Wire-guided endoscopic snare retrieval of proximally migrated pancreatic stents after endoscopic papillectomy for ampullary adenoma.
abstract: With the increasing use of pancreatic duct (PD) stents after endoscopic papillectomy (EP), complications such as proximal migration of the stent have become increasingly prevalent. A PD stent that migrates within a nondilated PD may be difficult to remove endoscopically. We performed endoscopic retrieval of proximally migrated PD stents after EP in 5 patients. Endoscopic retrieval was performed immediately after EP in one patient, the next day in 3 patients, and 2 weeks later in one patient. Wire-guided endoscopic retrieval was attempted in 4 patients, and the migrated stents were removed successfully in these 4 patients. No significant procedure-related complications occurred, other than mild pancreatitis in a single patient. In one patient, endoscopic retrieval performed immediately after EP failed when using the conventional method, and the migrated stent was removed using a minisnare without a guidewire the next day; this patient developed severe pancreatitis. Wire-guided endoscopic snare retrieval seems to be a safe and effective method for removing proximally migrated PD stents after EP.
