Biliary stent migration to hepatic duct-case report of a late complication.

Endoscopic retrieval of proximally migrated biliary plastic stents may be technically challenging and sometimes unsuccessful. Here we report the case of a 59-year-old woman with a migrated biliary stent in the right hepatic duct, which was diagnosed after the patient presented with cholangitis. The patient presented with constant abdominal pain in the right upper quadrant lasting for two days, along with nausea and bilious vomiting. The stent was retrieved by a polypectomy snare after failure of biliary basket and forceps. We performed a novel procedure for extraction of a migrated plastic stent, by using a polypectomy snare.
