Hemobilia following laparoscopic cholecystectomy: computed tomography findings and clinical outcome of transcatheter arterial embolization.

BackgroundHemobilia following laparoscopic cholecystectomy (LC) can occur in the early or late postoperative course and poses a diagnostic and therapeutic challenge.PurposeTo assess computed tomography (CT) findings and clinical outcomes after transcatheter arterial embolization (TAE) in patients presenting with hemobilia following LC.Material and MethodsFourteen patients treated for hemobilia following LC were included in the study. Three patients were diagnosed by endoscopy and 11 by abdominal contrast-enhanced CT. Coils or microcoils were superselectively deployed to occlude the bleeding vessel during TAE. Abdominal CT findings of hemobilia, and the success rate and complication of TAE were observed.ResultsAbdominal CT provided the following signs of hemobilia: hematoma within the abdominal cavity and gallbladder fossa, blood clots containing high attenuation within the bile duct, biliary dilatation, pseudoaneurysm of the right hepatic artery, contrast extravasation, enhancement of the bile duct wall, ...
