摘  要:目的探讨高频彩色多普勒超声在小儿肠套叠诊断中的应用价值。方法选取临床联合检查确诊的小儿肠梗阻患儿188例,其中肠套叠96例,非肠套叠92例。所有患儿均行腹部X片及高频彩色多普勒超声检查,比较腹部X线及高频彩色多普勒超声检查诊断的准确度、灵敏度及特异度,分析小儿肠套叠超声成像特征。结果腹部X线检查诊断准确度、灵敏度及特异度分别为73.94%、76.04%、71.74%;高频彩色多普勒超声检查诊断准确度、灵敏度及特异度分别为96.28%、96.88%、95.65%。高频彩色多普勒超声诊断准确度、灵敏度及特异度均较腹部X线检查显著升高,差异有统计学意义(P<0.05)。小儿肠套叠超声表现为横切面呈“同心圆”、“靶环征”,纵切面呈“套筒征”、“假肾征”,套入肠管周围可见肠系膜淋巴结继发肠梗阻时可见肠管扩张、腹腔积液、肠蠕动异常等。结论小儿肠套叠患儿采用高频彩色多普勒超声诊断可有效提升诊断准确度、灵敏度及特异度,明确小肠套叠超声成像特征,具有较高的临床应用价值。Objective To investigate the value of high-frequency color Doppler ultrasound in the diagnosis of pediatric intussusception.Methods Abdominal X-ray examination and high-frequency color Doppler ultrasonography were performed in 188 children with intestinal obstruction,including 96 cases of intussusception and 92 cases of non-intussusception.The accuracy,sensitivity and specificity were compared to analyze the ultrasonic characteristics of intussusception in children.Results The diagnostic accuracy,sensitivity and specificity of high-frequency color Doppler ultrasound(96.28%,96.88%and 95.65%,respectively)were higher than those of abdominal X-ray(73.94%,76.04%and 71.74%,respectively)(P<0.05).Ultrasonography showed“concentric circles”and“target ring sign”in the transverse section and"sleeve sign and“pseudo-kidney sign”in the longitudinal section.In addition,intestinal dilatation,ascites,intestinal peristalsis and abnormal peristalsis were observed when bowel obstruction secondary to mesenteric lymphadenopathy was present around the intestine.Conclusion High-frequency color Doppler ultrasound can effectively improve the diagnostic accuracy,sensitivity and specificity in children with intussusception.Ultrasonographic characteristics have a high clinical value in the diagnosis of small bowel intussusception.
