Dieulafoy lesion

A vascular defect in the mucosa of the gastrointestinal tract (typically the stomach, but sometimes other organs) in which an arteriole protrudes into the lumen and bleeds briskly. Dieulafoy lesions are an uncommon cause of massive gastrointestinal blood loss. The bleeding can be controlled with cauterization, rubber banding, wedge resection, or other techniques.
