Vascular Malformations of the Stomach and Duodenum: An Endoscopic Classification

Management of Gastrointestinal Angiodysplastic Lesions (GIADs): A Systematic Review and Meta-Analysis

“…Endoscopic studies have demonstrated a higher prevalence of lesions in the right colon, particularly the cecum, with prevalence rates ranging from 37 to 89 % ( 6,7 ). GIADs have been described in ~ 4 -7 % of patients presenting with upper GI tract bleeding ( 8,9 ).…”

Do Clinical Characteristics Predict the Presence of Small Bowel Angioectasias on Capsule Endoscopy?

“…Much of this uncertainty stems from our limited knowledge of the segmental distribution of these lesions and a lack of clinical predictors for the presence of AVMs in the GI tract. Data suggest that AVMs may cluster within intestinal segments [16], and it is estimated that 40-60% of patients have more than one lesion [17,18]. Further, the reported prevalence of concurrent upper and lower GI tract lesions varies from ''rare'' to as high as 33% [16,[19][20][21][22].…”

Polypoid arteriovenous malformation of colon mimicking inflammatory fibroid polyp

“…Thus, our case can be classified into type 2 arteriovenous malformation based on the Moore et al classification, 3 and this submucosal nodular form of arteriovenous malformation is very difficult to diagnose and treat endoscopically. 7 Although there are overlaps within the vascular lesions of the intestines, it is recommended to separate polypoid arteriovenous malformation from degenerative vascular abnormalities such a ectasia or angiodysplasia because the clinical manifestations and histogenesis may be different.…”
