Balloon-occluded retrograde transvenous obliteration (BRTO), a promising nonsurgical therapy for ectopic varices: a case report of successful treatment of duodenal varices by BRTO.

We present a patient with massive tarry stool, diagnosed as duodenal varices bleeding. Endoscopic ligation (EL) therapy was carried out for the varices, but because the possibility of re-bleeding remained, we treated the varices with balloon-occluded retrograde transvenous obliteration (BRTO), and duodenal varices were successfully decompressed without any complications. BRTO might be a novel therapeutic approach for ectopic varices, including duodenal varices.
