B超在小儿肠套叠的诊断和治疗中的作用

The Role of B-ultrasound in the Diagnosis and Treatment of Children Intussusception

目的探讨超声在诊断小儿肠套叠中的价值及对小儿肠套叠的治疗作用。方法分析我院行超声及X线平片检查并经手术或灌肠确诊的肠套叠患儿87例,以及均行超声及X线检查其他原因的腹痛患儿40例,分别计算B超和X线检查的特异度和灵敏度,分析其报告结果;并采用卡方检验比较超声监视下生理盐水灌肠复位和行X线监视下空气灌肠复位的治疗效果。结果 B超检查在灵敏度(96.5%)和特异度(83.3%)方面均高于X线检查(灵敏度73.17%,特异度77.8%);在B超监视下行生理盐水灌肠复位和行X线监视下空气灌肠复位的比较结果显示2χ=0.116,P>0.05,二者无统计学差异。结论超声不仅可作为诊断肠套叠的方法,而且可在实时超声图像的监视下进行复位。

Objective To explore the value of B-ultrasound in the diagnosis of children intussusception and its role in the treatment.Methods An analysis was made to 87 cases diagnosed to be of children intussusception after B-trasounand X-ray plain film examination and finally confirmed by surgery or enema;An analysis was also made to other 40 cases with abdominal pain of other causes after B-ultrasound and X-ray plain film examination;the specificity and sensitivity of B-ultrasound and X-ray plain film were calculated respectively;chi-square test was applied in the comparison of the curative effects between saline enema reduction under ultrasound monitoring and air enema reduction under X-ray monitoring.Result The sensitivity and specificity of B-ultrasound（96.5%/83.3%） were superior to those of X-ray（73.17%/77.8%）;the comparison between saline enema reduction under ultrasound monitoring and air enema reduction under X-ray monitoring showed that X2=0.116,P〈0.05,there existed no difference of statistic significance.Conclusions B-ultrasound can be applied in the diagnosis of intussusception and in reduction as well.
