A nine-year-old girl who developed life threatening hemobilia after blunt abdominal trauma was successfully managed by embolization of the hepatic artery aneurysm. However biliary fistula persisted and subcapsular liver abscess occurred after the endoscopic sphincterotomy and the placement of a nasobiliary drain for bile leakage. Debridement of the abscess and insertion of a drain tube eventually cured the event. The relevant literature is reviewed and the management of the hemobilia is discussed.
