Intraperitoneal hemorrhage as a major complication of percutaneous ethanol injection therapy for hepatocellular carcinoma

Abstract

Two cases of intraperitoneal hemorrhage, which is one of the major complications of percutaneous ethanol injection therapy for hepatocellular carcinoma, are reported. A 70-year-old man was hospitalized for treatment of a small recurrent hepatocellular carcinoma located on the surface of the left lobe of the liver. Acute hemoperitoneum developed after percutaneous ethanol injection therapy, but he was treated conservatively with blood transfusion, and recovered. The other patient was a 72-year-old man who was admitted for treatment of a solitary superficial hepatocellular carcinoma on the dome of the liver. Immediately after percutaneous ethanol injection, he suffered the sudden onset of severe abdominal pain with shock and massive hemoperitoneum. His bleeding was successfully controlled by emergency transcatheter arterial embolization. Our experience suggests that care must be taken when using percutaneous ethanol injection to treat patients with superficial hepatocellular carcinomas located on the surface of the liver. Moreover, transcatheter arterial embolization should be considered the treatment of choice for the management of uncontrollable intraperitoneal hemorrhage after percutaneous ethanol injection therapy.
