Fleeting Angiodysplasia

Vascular malformation of the gastrointestinal tract is an uncommon, but not rare, cause of gastrointestinal bleeding [1]. Indeed, especially in the elderly, angiodysplasia represents the most frequent cause of small bowel bleeding [2]. In the colon, the prevalence estimates vary widely, from <1% in asymptomatic patients to 2–40% in the setting of low gastrointestinal bleeding [3]. The burden is particularly high when considering patients evaluated for obscure gastrointestinal bleeding who ultimately are found to have non-small-bowel lesions within reach of conventional endoscopy.
