Preoperative diagnosis of cavernous hemangioma presenting with melena using wireless capsule endoscopy of the small intestine

摘要

Background and study aims: Primary neoplasms of the small intestine are relatively rare in all age groups, accounting for about 5?% of all gastrointestinal tumors 1. Cavernous hemangiomas of the small intestine are also rare, can cause gastrointestinal bleeding, and are extremely difficult to diagnose preoperatively 2. We present a patient who presented with melena and iron deficiency anemia, for whom wireless capsule endoscopy and single-balloon enteroscopy facilitated the diagnosis of cavernous hemangioma.
