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.

Because the artery reaches close to the muscularis mucosae in Dieulafoy disease, such fibers hold the artery to the muscularis mucosae as well.
Because gastric and colonic lesions are identical histologically, the same mechanisms may be extrapolated to play a role in colonic Dieulafoy disease.
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.
Dieulafoy disease should also be separated from other causes of lower gastrointestinal bleeding, like diverticular disease; telangiectasias (which may be associated with Osler-Weber-Rendu syndrome, Turner syndrome, and systemic sclerosis); vascular neoplasms; advanced liver disease causing mucosal spider nevi, which can cause bleeding similar to Dieulafoy disease14; and disorders of connective tissues affecting blood vessels.
