Endosonography-guided endoscopic band ligation of Dieulafoy's malformation: a case report.

Dieulafoy's vascular malformation may cause serious upper gastrointestinal hemorrhage. The mucosal lesion is usually small, and precise location of the lesion may therefore be difficult. We report a case of Dieulafoy's lesion successfully treated by endoscopic band ligation (EBL) where endoscopic ultrasonography (EUS), including Doppler examination, was applied for accurate diagnosis, guiding EBL and control of treatment.
