Case Reports
Management of a rare case of fulminant hemobilia due to arteriobiliary fistula following total pancreatectomy.
Hemobilia is a rare cause of acute upper gastrointestinal bleeding and is often associated with a history of hepatic or biliary tract injury, tumor growth, hepatic artery aneurysm, cholecystitis, or hepatic abscess. We report a case of a 76-year-old patient with massive hemobilia due to intrahepatic bleeding from the segment 8 hepatic artery without evidence of a true aneurysm, abscess, or metastatic disease 4 weeks following pylorus-preserving total pancreatectomy for pancreatic cancer. Gastroduodenoscopy suggested hemorrhage from the duodenojejunostomy but failed to achieve hemostasis, and the patient underwent exploratory laparotomy. ⋯ Computed tomography did not reveal any local liver or vascular pathology. Retrospectively, the cause of delayed profuse hemobilia was most likely a traumatic intrahepatic pseudoaneurysm following endoscopic bile duct stenting 3 weeks before the pancreatectomy. The reported case is exceptional and of particular interest because of the absence of a typical history or cause of hemobilia, preoperative misleading diagnostic results in an altered anatomic situation, and the operative management to achieve bleeding control in this emergency setting.
