摘　　要：目的:探讨螺旋CT对成人小肠套叠的诊断及临床价值。方法:回顾分析20例经手术及病理证实的小肠套叠的螺旋CT表现及病理改变。结果:20例小肠套叠中小肠-小肠套叠15例,小肠-结肠套叠5例。CT表现直接征象有:靶形征10例,彗星尾征或肾形征7例,漩涡征3例。间接征象有:肠壁增厚12例,肠腔扩张16例,肠梗阻16例,邻近肠系膜或筋膜浸润4例等。20例小肠套叠的病因分别为:原发癌8例,转移瘤4例,淋巴瘤3例,息肉2例,平滑肌瘤1例,美克尔憩室1例,阑尾炎1例。结论:螺旋CT对小肠套叠的诊断和治疗有重要的指导作用。Objective：To explore the diagnosis of the adult intussusception by spiral CT and its clinical value. Methods：20 cases of the small intussusception confirmedby surgery and pathology were retrospectively analyzed by spiral CT and pathological changes. Results：20 cases of small intestine intussusceptions, including 15 cases of small irttestine-small intestine intussusceptions and 5 cases of small intestine colon intussusception. Direct findings by CT： target sign in 10 cases, comet tail or reniform sign in 7 eases, whirl sign in 3 eases. Indirect signs are： bowel thickening in 12 cases, bowel cavity expansion in 16 cases, intestinal obstruction in 16 cases, adjacent mesenteric or fascia infiltration in 4 eases. Causes for 20 eases of small intestine intussusception are： primary tumors in 8 eases, metastasized tumors in 4 eases, lymphomas in 3 cases, polyposis in 2 cases, leiomyoma in 1 ease, Meckel divertieultun in 1 ease, and appendicitis in 1 case. Conclusion： Spiral CT provides important guidance in the diagnosis and treatment of small intestine intussusception
