Vascular ectasia of the duodenum detected by duodenoscopy.

A 65-yr-old Chinese woman suffered from repeated episodes of upper gastrointestinal bleeding for 5 yr. Despite repeated panendoscopic and angiographic studies, the bleeder was not found until a duodenoscopic examination was performed. A small bleeder was found near the papilla vater area. The lesion was excised and proved to be a vascular ectasia of duodenum.
