[A Case of Bismuth III b Hilar Cholangiocarcinoma Resected with Extended Left Hepatic Lobectomy after ERCP Induced Pancreatitis].

Endoscopic retrograde cholangiopancreatography(ERCP)is widely accepted as the standard therapy before surgery for hilar cholangiocarcinoma. The patient is a 68-year-old man who presented with liver dysfunction. Computed tomography (CT)revealed abnormal lesions in his liver. He was referred to our hospital for therapy. We present a rare case of expansion of left lobectomy for Bismuth III b hilar cholangiocarcinoma after grade 2 severe pancreatitis caused by ERCP. He received arterial infusion therapy and endoscopic necrosectomy 6 times and percutaneous transhepatic biliary drainage(PTBD). The surgical procedure could be performed after the severe pancreatitis resolved. His postoperative course was uneventful.
