Proximally migrated pancreatic stent successfully removed using needle-knife and forceps: Complication after precut papillotomy assisted by pancreatic stenting

SummaryPancreatic stent-assisted ampullary precut papillotomy is a rescue method for cases with difficult bile duct cannulation during endoscopic retrograde cholangiopancreatography (ERCP). We describe a case in which post-ERCP pancreatitis (PEP) developed due to the proximal migration of pancreatic stent, after precut papillotomy. Removal of the migrated pancreatic stent was achieved after needle-knife incision of the pancreatic duct's orifice followed by retrieval of the stent using rat-tooth forceps, which resulted in rapid resolution of the PEP. Caution is needed when pancreatic stent is placed after papillary incision. Needle-knife incision of the pancreatic duct orifice followed by forceps removal is an effective technique for rescuing pancreatic stent migration.
