Core Tip
Core tip: Despite the high diagnostic yield of small bowel capsule endoscopy (SBCE) in the study of iron-deficiency anemia (IDA), the clinical relevance and bleeding potential of findings such as red spots or mucosal erosions (P1 lesions) remain uncertain. We found that P1 lesions were commonly found in the SBCE of patients with IDA and their presence was associated with non-steroidal anti-inflammatory drugs use. The outcomes of patients with P1 lesions do not differ significantly from those with P0 lesions or normal SBCE. An algorithm with a stepwise approach to the patients with IDA who are submitted to SBCE is proposed.
