A prospective evaluation of iron deficiency anemia in the GI endoscopy setting: role of standard endoscopy, videocapsule endoscopy, and CT-enteroclysis
After conventional endoscopy, the cause of anemia remains unknown in up to 40% of patients. This study involved 189 patients with IDA, including 98 women and 91 men; mean (±standard deviation) age 68 years±16.6 years. Endoscopy results were positive in 144 of 189 patients (76.2%). CT-enteroclysis and VCE allowed a diagnosis in 37 of 45endoscopy-negative patients.
