Transcatheter arterial chemoembolization (TACE) has been widely used as a palliative treatment for patients with unresectable hepatocellular carcinomas (HCCs) [1]. TACE is a relatively safe procedure, with a complication rate of < 1 % [2]. Hemobilia after TACE has very occasionally been reported [3], but endoscopic visualization of hemobilia has not been reported.

A 63-year-old man presented to our hospital with abdominal pain, fever, and jaundice. He had been diagnosed 3 months earlier with alcoholic liver cirrhosis and unresectable HCC (4 cm, segment 8), and had been treated with TACE in our hospital. His laboratory test results were as follows: total bilirubin 10.5 mg/dL; aspartate transaminase 1098 IU/L; and alanine transaminase 891 IU/L. Computed tomography (CT) revealed newly developed intraductal masses or blood clots in the common bile duct (CBD) and intrahepatic duct (IHD), with upstream IHD dilatation. Endoscopic retrograde cholangiopancreatography (ERCP) revealed multiple filling defects in the bile duct ([Fig. 1]). Multiple blood clots were extracted with a stone basket and balloon catheter ([Fig. 2]). Therefore, hemobilia was suspected. After the ERCP, the abdominal pain and fever improved.

On day 3 after the ERCP, the patient experienced dizziness, melena, and a progressive decrease in hemoglobin level. Angiography revealed no extra flow of contrast to the bile duct ([Fig. 3]). Repeat ERCP with single-operator cholangioscopy (SpyGlass DS; Boston Scientific, USA) was performed to identify the bleeding focus ([Video 1]). Cholangioscopy revealed many blood clots in the CBD. A tumorous mass in the hepatic hilum suggested direct HCC invasion of the bile duct. Cholangioscopy also revealed active bleeding from the left IHD, at the distal end of the tumor. After further advancement of the cholangioscope, we observed a damaged bile duct owing to ischemic damage after TACE. Small pulsating blood vessels on the surface of the bile duct showed active bleeding. A self-expandable metal stent was placed to compress the bleeding bile duct ([Fig. 4]). Thereafter, the patient’s condition stabilized without further evidence of bleeding.

To the best of our knowledge, this is the first reported case of post-TACE hemobilia diagnosed using cholangioscopy. Identifying the bleeding focus accurately using cholangioscopy can help to determine the most appropriate treatment method.
