In patients with obscure gastrointestinal bleeding, capsule endoscopy provides a high degree of diagnostic aid. The best candidates for this procedure are patients with obscure-overt bleeding who have required blood transfusions. Capsule endoscopy has a positive influence on an important proportion of patients, whether oriented towards new diagnostic techniques or towards a definitive treatment.
Small bowel tumors are not an infrequent cause of OGIB. Capsule endoscopy, even if it does not allow determination of the benign or malignant nature or the histologic type of the tumor, is a useful tool for the diagnosis and early management of these tumors.
The present evidence-based guidelines are focused on the use of device-assisted enteroscopy in the management of small-bowel diseases. A panel of experts selected by the Spanish and Portuguese small bowel study groups reviewed the available evidence focusing on the main indications of this technique, its role in the management algorithm of each indication and on its diagnostic and therapeutic yields. A set of recommendations were issued accordingly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
