Dieulafoy lesion as a cause of massive gastrointestinal bleeding.
The Dieulafoy lesion, also referred to as exulceratio simplex, caliber-persistent artery anomaly, or cirsoid aneurysm, is a relatively rare, yet possibly fatal cause of gastrointestinal bleeding. Recent journal articles suggest that this pathological entity is not as uncommon as once thought. Advances in endoscopic technique and esophagogastroduodenoscopy (EGD) have greatly assisted in earlier diagnosis and added options to the treatment regimen for this lesion. The relationship of this anomaly to possible exsanguination makes it essential that both medical and surgical endoscopists be knowledgeable of the anatomy, diagnosis, and management of this pathology. Several therapeutic approaches to Dieulafoy's lesion are available and are described.
