彩色多普勒超声诊断小儿肠套叠

目的 探讨彩色多普勒超声（CDFI）对小儿肠套叠的诊断及辅助临床选择复位方式的价值。方法 回顾分析90例经CDFI诊断，并经X线空气灌肠复位或手术复位小儿肠套叠资料。结果 经X线空气灌肠复位成功79例（87．8％），10例行手术治疗（11％）后复位成功，超声误诊1例，超声确诊率98．8％。肠壁严重水肿，阻力指数（RI）显著升高，无血流显示等情况时禁忌空气灌肠，应尽快手术复位。结论CDFI对小儿肠套叠的诊断符合率高，可作为影像学首选的检查方法，并且对临床选择肠套叠复位方式有一定的价值。

The value of color Doppler ultrasonographg for diagnosing the intussusception in children

Objective To investigate the value of color Doppler ultrasonngraphy for diagnosing children＇s intussusceptions and its significance for choosing the way of reduction. Methods Ninety children with intussusception confirmed by X- ray gaseous enema reduction or operative reduction were underwent ultrasonography and analyzed retrospectively. Results Among all pediatric patients with intussusception, 79（89.8% ）cases were confirmed by X- ray gaseous enema reduction, 10 cases（ 11% ）were confirmed by operative reduction. 1 cases were misdiagnosed and therefore the diagnostic ratio of ultrasonogvaphy was 98.8%. Operative reduction should be performed quickly when heavily swelling intestinal wall, significantly high RI, especially no flow imaging are demonstrated in color Doppler ultrasonography. Conclusion Uhrasonography is an important tool in the sereenng and diagnosis of patients with suspected intussusception and it has a great value in how to choose the way of reduction.
