The diagnostic focus explains that angiodysplasia results from dilated submucosal veins and arteriovenous malformations, with higher incidence after age 60 and frequent localization in the right colon. Risk associations include advanced renal disease, von Willebrand disease, and aortic stenosis, with acquired vW factor deficiency proposed as a mechanism. Endoscopic evaluation may miss lesions if bowel preparation is inadequate, while endoscopic therapy suits patients with significant bleeding or anemia.","cbCaieK2OcKgwnRj","https://ap.wps.com/l/cbCaieK2OcKgwnRj","pdf",61431624,1,1778361904,{"code":4,"msg":22,"data":23},"ok",{"site_id":24,"language":25,"slug":26,"title":13,"keywords":27,"description":14,"schema_data":28,"social_meta":62,"head_meta":64,"extra_data":66,"updated_unix":20},105,"en","educational-objective-angiodysplasia-as-a-cause-of-painless-gastrointestinal-bleeding","",{"@graph":29,"@context":61},[30,47],{"@type":31,"itemListElement":32},"BreadcrumbList",[33,37,41,44],{"item":34,"name":35,"@type":36,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":38,"name":39,"@type":36,"position":40},"https://docshare.wps.com/document/","Document",2,{"item":42,"name":12,"@type":36,"position":43},"https://docshare.wps.com/document/healthcare/",3,{"item":45,"name":13,"@type":36,"position":46},"https://docshare.wps.com/document/educational-objective-angiodysplasia-as-a-cause-of-painless-gastrointestinal-bleeding/30830",4,{"url":45,"name":13,"@type":48,"author":49,"headline":13,"publisher":51,"fileFormat":54,"description":14,"dateModified":55,"datePublished":55,"encodingFormat":54,"isAccessibleForFree":56,"interactionStatistic":57},"DigitalDocument",{"name":9,"@type":50},"Person",{"url":34,"name":52,"@type":53},"DocShare","Organization","application/pdf","2026-05-09",true,{"@type":58,"interactionType":59,"userInteractionCount":4},"InteractionCounter",{"@type":60},"ViewAction","https://schema.org",{"og:url":45,"og:type":63,"og:title":13,"og:site_name":52,"og:description":14},"article",{"robots":65,"canonical":45},"index,follow",{"doc_id":7,"site_id":24}]
