Pancreaticoduodenal artery pseudoaneurysm-induced hemobilia caused by a plastic biliary stent

Abstract : Summary of EventMelena with abdominal pain were developed in a patient who had undergone endoscopic retrograde cholangiopancreatography (ERCP) with common bile duct stones removal and endoscopic retrograde biliary drainage (ERBD) using a plastic biliary stent. He subsequently underwent laparoscopic cholecystectomy. For the diagnosis and treatment of hemobilia caused by a plastic biliary stent, selective angiography for gastroduodenal artery with subsequent embolization for small pseudoaneurysm of pancreaticoduodenal artery was done successfully.Teaching PointA plastic biliary stent induced pseudoaneurysm can be a cause of hemobilia after ERCP with ERBD procedure. Selective angiography with embolization for bleeding pseudoaneurysm can be an effective treatment for this situation.
