Abstract: Small bowel endoscopy is indicated for patients with an unidentified bleeding site in esophagogastroduodenoscopy and ileocolonoscopy and symptoms of intestinal blood loss or unexplained anemia. In approximately two-thirds of these cases, capsule endoscopy (CE) detects a lesion within the small bowel that explains the patient's symptoms. In few cases, though, lesions outside of the small bowel might be revealed by CE. Therefore, attention to all intestines that are visualized by CE might be necessary not to overlook bleeding sites that had not been discovered by prior flexible endoscopy.

Here the case of a 71-year-old male patient with unexplained anemia is presented by the authors. Small-bowel CE revealed minor bleeding from a neoplastic mass in the cecum. The final diagnosis of an adenocarcinoma of the ascending colon was established after the patient underwent a right hemicolectomy. This article is part of an expert video encyclopedia.
