Overview
Hemobilia is a rare but severe condition characterized by bleeding into the biliary tree, often presenting as upper gastrointestinal hemorrhage. It can result from various causes including hepatic artery aneurysms, biliary tract trauma, or iatrogenic injury. 1Diagnosis
Key Diagnostic Criteria: Upper gastrointestinal bleeding with bile in the gastric aspirate or nasogastric tube.
Recommended Tests: Emergency celiac and selective hepatic artery angiography.
Imaging Findings: Hepatic artery pseudoaneurysms, cystic artery pseudoaneurysms, diffuse hemorrhage of hepatic artery branches, or bile duct fistulae. 1Management
First-Line Treatment: Transarterial embolization using Gelfoam particles and/or coils to occlude the bleeding vessel.
Targeted Embolization: Embolization of the hepatic artery branch proximal to the bleeding point.
Rebleeding Management: Repeat embolization for recurrent bleeding if necessary. 1Special Populations
No Specific Data Provided: The abstracts do not cover management specifics for pregnancy, pediatrics, elderly patients, or comorbidities. 1Key Recommendations
Perform emergency selective hepatic angiography for rapid diagnosis and treatment in cases of massive hemobilia. (Evidence: Moderate) 1
Initiate transarterial embolization as the first-line intervention to control bleeding in hemobilia. (Evidence: Strong) 1
Consider repeat embolization if rebleeding occurs post-initial treatment. (Evidence: Weak) 1References
