Duodenal varices(DV)are the most common of ectopic varices. Although bleeding from DV is rare, it is difficult to control bleeding and sometimes fatal. We have encountered four clinical cases of ruptured DV. Case 1:A man in his 80s presented with a history of partial gastrectomy with Billroth-II reconstruction and LC due to chronic hepatitis C. We performed single-balloon endoscopy and injected 67% N-butyl-2-cyanoacrylate(NBCA)for DV on the afferent loop with red plug. Case 2:A woman in her 40s with primary biliary cirrhosis complained of tarry stool and anemia. We performed endoscopic injection sclerotherapy(EIS)with 67% NBCA for spurting bleeding point in duodenum. Case 3:A man in his 50s with liver cirrhosis(LC)due to chronic hepatitis B complained of tarry stool. We performed endoscopic variceal ligation(EVL)and balloon-occluded retrograde transvenous obliteration(B-RTO)for DV. Case 4:A man in his 60s with alcoholic LC complained of tarry stool. We performed EIS with 67% NBCA for DV. We added EVL, clipping, and argon plasma coagulation after EIS to control bleeding. To control bleeding was achieved in all cases.

A 36-year-old man diagnosed with Charcot-Marie-Tooth(CMT)disease type 1B was treated in the department of neurology of this hospital. Due to a liver injury(AST 237IU/ml, ALT 496IU/ml)which occurred in November 200X, he was introduced to our department. As a result of scrutiny, we diagnosed him with chronic hepatitis C genotype 2a(HCV-RNA 5.4logIU/ml).He will be admitted to the hospital for Interferon(IFN)therapy in April next year. Although the mechanism is unknown, there are a few reports of peripheral neuropathy related to IFN therapy. Therefore, IFN therapy is generally unfavorable for patients with neuromuscular disorders. There are several IFN preparations used in Japan. IFN alfa associated peripheral neuropathy appears less than 0.1-5% of the time. While there is no report of peripheral neuropathy related to IFN beta, we performed IFN beta and Rivabirin combination therapy with a severe follow-up by a neurologist. We could accomplish treatment without the exacerbation of neurologic symptoms. He achieved sustained viral response. When IFN therapy was provided for chronic hepatitis B or chronic hepatitis C complicated with peripheral neuropathy, there is some possibility of performing antiviral therapy safely by using IFN beta.
