目的评价螺旋 CT 对成人肠套叠的诊断价值,并对肠套叠原发病诊断价值进行分析。方法对浙江大学附属邵逸夫医院和浙江丽水市中心医院68例经手术证实为成人肠套叠的 CT 资料进行回顾性分析,男42例、女26例,年龄30～82岁(平均52.5岁),病程3 d 至13个月。结果68例肠套叠中,CT 诊断出66例,达97.1%。主要直接征象有:(1)同心圆征或彗星尾征,66例;(2)血管卷入征,61例;(3)脂肪征,58例。主要间接征象有:(1)靶环征,19例;(2)肠梗阻,24例;(3)腹水,4例;(4)其他征象如邻近肠系膜或筋膜浸润4例,腹膜后淋巴结增大8例。螺旋 CT 对肠套叠原发病诊断的准确率为72.1%。结论螺旋 CT 对诊断成人肠套叠及其原发病具有重要价值,诊断肠套叠的特异性征象是同心圆征、血管卷入征和脂肪征。
Objective To evaluate the diagnostic value of spiral CT in adult intussusception and to analyze the diagnostic value of primary intussusception. Methods A total of 68 males and 26 females, aged 30-82 years (average 52.5 years), were retrospectively analyzed. Sixty-eight cases of surgically confirmed intussusception in Run Shaw Hospital and Zhejiang Lishui Central Hospital of Zhejiang University were retrospectively analyzed. , Duration of 3 d to 13 months. Results 68 cases of intussusception, CT diagnosis of 66 cases, up to 97.1%. The main direct signs are: (1) concentric or comet tail syndrome, 66 cases; (2) vascular involvement, 61 cases; (3) fat syndrome, 58 cases. The main indirect signs were: (1) target ring sign in 19 cases; (2) intestinal obstruction in 24 cases; (3) ascites, 4 cases; (4) other signs such as adjacent mesenteric or fascia infiltration in 4 cases, retroperitoneal lymph node Increased in 8 cases. The accuracy of spiral CT in diagnosing primary intussusception was 72.1%. Conclusion Spiral CT is of great value in the diagnosis of intussusception and its primary disease. The specific signs of intussusception are concentric circles, vascular involvement and fat sign.
