摘　　要：小肠肿瘤发生率极低,约占胃肠道肿瘤的1%,其中小肠良性肿瘤以平滑肌瘤和腺瘤较为多见,脂肪瘤相对少见。小肠脂肪瘤多发于60~70岁老年人,起源于成熟脂肪细胞,边界清楚,在远端回肠及回盲瓣黏膜下层较常见。约70%的脂肪瘤无症状,有症状者多表现为肠梗阻或肠套叠,而以消化道出血为首要症状的更为少见,本文报道了我科诊治的1例因肠道脂肪瘤导致间歇性黑便的病例。The incidence of small intestinal tumors is very low, accounting for 1% of gastrointestinal tumors, of which benign tumors of the small intestine are more common in leiomyoma and adenoma. Small intestinal lipoma occurs from 60 to 70 years old people, which originated from mature adipocytes and with clear boundary. The lesion is often located in the distal ileum and ileocecal valve submucosa. Approximately 70% lipoma can be asymptomatic, symptomatic manifestations include intestinal obstruction or intussusception. Gastrointestinal hemorrhage is rarely seen in clinical practice, the current paper reported one case intermittent melena caused by intestinal lipoma in our department.
