Angiodysplasia of the Duodenum 3

Angiodysplasia is characterized by degenerative vascular dilation of the capillary net in the absence of dysplastic tissue. On endoscopy, flat or slightly elevated, reddish, roundish or starry lesions are observed, measuring normally between 2 and 10 mm. Angiodysplasia is a frequent cause of unexplained upper gastrointestinal bleeding with significant morbidity.
