A Case of Chronic Recurrent Small Bowel Bleeding in Neurofibromatosis Type 1 Diagnosed by Capsule Endoscopy / 대한소화기내시경학회지

ABSTRACT

Small bowel diseases comprised of neoplasm, inflammatory disease, vascular abnormality, absorption dysfunction, and iatrogenic causes. Among those, vascular abnormality is perhaps the most important clinical disease entity. Obscure gastrointestinal bleeding accounts for 5% of chronic gastrointestinal bleeding, but conventional endoscopy and radiologic study may fail to diagnose the cause in certain cases. Patients with neurofibromatosis type 1 have a lot of gastrointestinal tumor, with a high incidence of small bowel involvement. We experienced a case presenting with chronic bleeding due to jejunal gastrointestinal stromal tumor diagnosed by capsule endoscopy in a seventy-two year old female patient with sporadic neurofibromatosis type 1.
