Small intestinal lipomas are rare, but may cause obscure gastrointestinal bleeding. The endoscopic unroofing technique excises only the upper third of the lipoma and allows both histological confirmation and complete treatment with minimal risk of perforation. We present a rare case of obscure gastrointestinal bleeding caused by a jejunal lipoma. A 75-year-old man on antiplatelet therapy presented to our department with melena and anemia. Computed tomography revealed he had a 45-mm jejunal submucosal tumor with fat attenuation. Endoscopic resection using an endoscopic unroofing technique with double balloon enteroscopy was successfully performed. The tumor was confirmed to be a lipoma.
小肠脂肪瘤很罕见，但可能导致不明原因的胃肠道出血。内镜下掀盖技术仅切除脂肪瘤的上三分之一，既能进行组织学确诊，又能在穿孔风险最小的情况下实现彻底治疗。我们报告一例由空肠脂肪瘤引起的不明原因胃肠道出血的罕见病例。一名正在接受抗血小板治疗的75岁男性因黑便和贫血前来我院就诊。计算机断层扫描显示他有一个45毫米的空肠黏膜下肿瘤，呈脂肪衰减。使用双气囊小肠镜的内镜下掀盖技术成功进行了内镜切除。肿瘤经确诊为脂肪瘤。
