要旨●患者は20歳代,女性.下血と意識障害にて緊急入院,小腸カプセル内視鏡検査にて空腸病変からの出血を認めた.ゾンデ法小腸X線造影検査・小腸ダブルバルーン内視鏡検査にて頂部に粘膜欠損を伴う粘膜下腫瘤を認め,出血源と考えられた.腹腔鏡下小腸部分切除を施行し,詳細な病理組織学的検索結果から空腸Dieulafoy's lesionと診断した.近年,小腸検査の発達により小腸血管性病変の報告は増えてきているが,今回大量下血で発症し,粘膜下腫瘤様の形態を呈した空腸Dieulafoy's lesionを経験したので報告する.
A 20-year-old female was sent to hospital after two severe episodes of intestinal blood discharge. Capsule endoscopy revealed a white elevation and bleeding in the jejunum, and the patient was diagnosed with small bowel hemorrhage. Subsequently, a SMT(submucosal tumor)was recognized with double balloon endoscopy and X-ray fluoroscopic examination of the jejunum. Small bowel segmental dissection was performed for further investigation. Based on the pathology, we diagnosed the patient with a Dieulafoy-like lesion. Significant improvement of small intestine inspection has recently resulted in a number of Dieulafoy-like lesions being reported. This case clearly indicates the need to contemplate Dieulafoy-like lesions as a differential diagnosis to SMT in cases of repetitive bleeding.
