A patient with obstructive jaundice due to bleeding in the common bile duct after ultrasound-guided liver biopsy.

A-63-year-old man was referred to our hospital for interferon therapy to treat chronic hepatitis C. The patient complained of right upper abdominal pain 1 hour after the ultrasound-guided liver biopsy. Bleeding in the gallbladder and the common bile duct were found on emergency CT. Obstructive jaundice due to the common bile duct hematoma was diagnosed, and endoscopic retrograde cholangiopancreatography(ERCP) was performed, and a filling defect thought to be a hematoma was seen in the bile duct on cholangiography. The hematoma in the bile duct was extracted after endoscopic sphincteroyomy.
