目的探讨彩色多普勒超声对小儿肠套叠辅助诊断的临床价值及意义,为临床复位治疗提供指导。方法选择2007-01-2010-12来广西壮族自治区妇幼保健院超声科检查过的165例肠套叠患儿,回顾性分析彩色多普勒超声图像特征。结果 165例经临床证实肠套叠患儿,彩色多普勒超声检出161例,4例无典型征象而漏诊,超声检出率为98%。肠套叠的超声特征性改变为“同心圆征”和“套筒征”。超声发现的161例肠套叠中,156例检测出肠壁血流信号,5例未检测到血流信号,其中这5例经手术后证实为肠坏死。结论经腹部彩色多普勒超声检查小儿肠套叠检出率高、特异性强,能够早发现、早确诊,安全可靠,为临床复位治疗提供了客观的依据。
Objective To investigate the clinical value and significance of color Doppler ultrasound in the diagnosis of pediatric intussusception and provide guidance for clinical treatment. Methods A total of 165 patients with intussusception examined by Department of Ultrasound, MCH Hospital of Guangxi Zhuang Autonomous Region from January 2007 to October 2010 were retrospectively analyzed for color Doppler ultrasound image characteristics. Results 165 cases of clinical intussusception in children with intussusception, color Doppler ultrasound in 161 cases, 4 cases without typical signs of missed diagnosis, ultrasound was 98%. Ultrasonic characteristics of intussusception changed to “concentric circles levy” and “sleeve levy”. Among the 161 intussusception cases detected by ultrasound, 156 cases detected intestinal wall blood flow signals and 5 cases did not detect blood flow signals, of which 5 cases were confirmed as intestinal necrosis after surgery. Conclusion The results of transrectal color Doppler ultrasonography showed that the detection rate of intussusception in children is high and the specificity is high. Early detection, early diagnosis, safety and reliability provide an objective basis for clinical treatment.
