Fr. physician, 1839–1911.

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.

Dieulafoy triad

Tenderness, muscular contraction, and skin hyperesthesia at the McBurney point in acute appendicitis.

Dieulafoy disease is also known as Dieulafoy lesion or ulcer, caliber persistent artery, gastric aneurysm, gastric arteriosclerosis, submucosal arterial malformation, cirsoid aneurysm, and solitary exulceration simplex.
Of late, there have been increasing reports of extragastric Dieulafoy disease. It has been reported in the lip, esophagus, duodenum, jejunum, ileum, cecum, right transverse, left colon, rectum, (2) anal canal, (3) gall bladder, and bronchus.
Although Dieulafoy disease has no direct disease associations, alcohol intake and nonsteroidal antiinflammatory drug use are said to increase the chances of bleeding from a gastric lesion by causing mucosal erosions.
Because the artery reaches close to the muscularis mucosae in Dieulafoy disease, such fibers hold the artery to the muscularis mucosae as well.
The most important differential diagnosis for Dieulafoy disease is angiodysplasia because both are right sided and present with sudden onset of massive lower gastrointestinal bleeding.
