Therapeutic strategy for patients with bleeding rectal varices complicating liver cirrhosis

Although rupture of rectal varices is rarely encountered, it may provoke massive and fatal hemorrhage in patients with liver cirrhosis. We examined the clinical features of patients showing bleeding from rectal varices to establish a suitable therapeutic strategy for the lesions.

A case of liver cirrhosis due to hepatits C virus infection complicating giant anorectal varices treated with balloon-occluded retrograde transvenous obliteration.

A 73-year-old man with liver cirrhosis due to hepatitis C virus infection was admitted to our hospital because of massive bleeding from external varices. Colonoscopic examination revealed that giant anorectal varices had developed between the anus and rectal ampulla, and had ruptured at the perianal site. On three-dimensional computed tomography imaging, the feeding and drainage vessels of the varices were identified as the inferior mesenteric vein and right inferior hemorrhoidal vein, respectively. Endoscopic therapies were not employed for the bleeding varices, because the blood flow volume of the feeding vessel was extremely large. Balloon-occluded retrograde transvenous obliteration (B-RTO) was therefore carried out through the drainage vessels. The variceal blood flow disappeared after B-RTO therapy, and the varices decreased in size with thrombus formation verified by colonoscopy. Bleeding from the external varices also ceased. B-RTO therapy may be an effective approach for giant anorectal varices presenting as a complication in liver cirrhosis patients in whom the main drainage vessels can be determined.

Transcatheter arterial chemoembolization for hepatocellular carcinoma: Comparison of the therapeutic efficacies between miriplatin and epirubicin.

The therapeutic efficacy of transcatheter arterial chemoembolization (TACE) using miriplatin was evaluated in comparison with that using epirubicin in patients with hepatocellular carcinoma (HCC).
