Factores diferenciales de etiología tumoral de la anemia ferropénica de probable origen digestivo

In IDA, colonoscopy (or contrast barium enema in certain circumstances) is the most important exploration to rule out malignancy. Only NSAID use is useful to exclude cancer. Patients without identifiable lesions have a favorable prognosis. A moderate frequency of synchronous lesions was found. We recommend a complete conventional GI endoscopic study if no evident bleeding lesion is found during the initial endoscopic procedure. Capsule endoscopy and celiac disease serology are useful in obscure gastrointestinal bleeding.
