Haemobilia merely refers to the presence of blood in the biliary tract.
Classical clinical triad, only seen in approximately 50% of cases, consists of:
- abdominal pain
Two-thirds of cases of hemobilia are iatrogenic (e.g. PTC) while trauma accounts for 5%. Haemobilia may manifest many weeks after the initial injury.
- iatrogenic (surgical or percutaneous procedures)
- aneurysm of hepatic artery (can cause massive haemobilia)
- tumors (most commonly HCC)
- GI bleed due to gall stones
Ultrasound is often the first investigation and reveals echogenic material in bile ducts and dilated gallbladder.
High-attenuation clot within the bile ducts.
