An 80-year-old man with persistent anemia was suspected to have a hemorrhagic lesion in the small intestine and he underwent investigation by capsule endoscopy. This examination revealed several erosions and reddened lesions in the pelvic small intestine (Figure [1]). On 17 May 2005 he was started on a prostaglandin inducer, rebamipide, at a daily dose of 300 mg, and although the iron preparation he was on was stopped, there was no decrease in his hemoglobin level. On 1 July a second capsule endoscopy examination revealed marked improvement - the erosions and reddened lesions in the small intestine had resolved (Figure [2]). The second capsule endoscopy allowed observation nearly as far as the terminal ileum, where a protruding lesion was detected (Figure [3]). Double-balloon endoscopy revealed a red type Ip polyp, about 30 cm proximal to the ileocecal valve (Figure [4]). In addition, there was an advanced cancer resembling a type IIc early cancer in the ascending colon (Figure [5]).

On 29 August 2005 the patient underwent surgery. The lesion in the large bowel was diagnosed as a moderately differentiated adenocarcinoma (ss, ly1, v1, n0) and the lesion in the ileum as a well-differentiated adenocarcinoma with a component of tubular adenoma (sm1, ly0, v0). There was also a type IIc early cancer in the stomach and this lesion was resected endoscopically. The entire clinical course is summarized in Figure [6]. It was not possible to determine whether this patient’s anemia had been caused by the small-intestinal lesions or by the advanced large-bowel cancer. Rebamipide, a mucoprotective agent, might be effective for the management of patients with erosions or reddened lesions in the small intestine [1] [2] [3].

Capsule endoscopy proved useful for the diagnosis of the small-intestinal lesions in this patient, but we should be aware that this method cannot provide a diagnosis of lesions that the capsule cannot reach and that it can miss small lesions in stomach.
