高频超声对小儿肠套叠诊治价值的研究

The study on the value of high-frequency ultrasound in the diagnosis and treatment of intussusception in children

目的 研究并探讨高频超声对小儿肠套叠的诊治价值。方法 选择2015年1月至2017年12月就诊于本院的90例疑似小儿肠套叠患儿,所有患儿均接受高频超声、X线检查,分析超声图像、X片,作出诊断。以临床综合确诊结果为参照,计算和比较高频超声、X线对小儿肠套叠的诊断灵敏度、特异度、准确率,并分析高频超声、X线诊断小儿肠套叠的结果与确诊结果之间的一致性。在高频超声引导下,对小儿肠套叠确诊患儿实施空气加压灌肠治疗,观察其治疗效果。结果 高频超声对小儿肠套叠的诊断灵敏度、特异度、准确率分别为95.65%、95.24%、95.56%,其对小儿肠套叠的诊断灵敏度、准确率高于X线,差异有统计学意义(P<0.05),但高频超声与X线的特异度比较,差异无统计学意义(P>0.05)。经一致性分析,高频超声对小儿肠套叠的诊断结果与确诊结果之间的一致性良好,而X线对小儿肠套叠的诊断结果与确诊结果之间的一致性未达到良好。在高频超声引导下实施空气加压灌肠治疗后,小儿肠套叠患儿的复位成功率达到100%,无中转手术病例。结论 高频超声对小儿肠套叠可进行灵敏、准确诊断,具有较高的诊断价值,还可引导空气加压灌肠治疗,有利于提高肠套叠复位成功率。

Objective To study and explore the value of high-frequency ultrasound in the diagnosis and treatment of intussusception in children.Methods 90 children suspected as intussusception in our hospital from January 2015 to December 2017 were selected.All children underwent high-frequency ultrasound and X-ray examination,and ultrasound and X images were analyzed.The sensitivity,specificity,and accuracy of highfrequency ultrasound and X-ray in the diagnosis of intussusception in children were calculated and compared.The consistency between the results of high-frequency ultrasound and X-ray in the diagnosis of pediatric intussusception and the results of diagnosis were compared.Under the guidance of high frequency ultrasound,children with intussusception was treated with aero-pressor-therapy,and the therapeutic effect was observed.Results The sensitivity,specificity,and accuracy of high frequency ultrasound in the diagnosis of pediatric intussusception were 95.65%,95.24%,95.56%,the diagnostic sensitivity,accuracy of high frequency ultrasound were higher than those of X-ray(P<0.05),but there was no statistically significant difference in the specificity between high frequency ultrasound and X-ray(P>0.05).The conformance analysis showed that there was a good consistency between the results of high-frequency ultrasound and the results of diagnosis for pediatric intussusception,while the consistency between X-ray and the results of diagnosis for pediatric intussusception was not good.After aero-pressor-therapy guided by high frequency ultrasound,the success rate of pediatricintussusception reduction was 100%,without case of transfer operation.Conclusion High frequency ultrasound can make sensitive and accurate diagnosis for intussusception in children.It has high diagnostic value,can also guide aero-pressor-therapy,which is beneficial to improve the success rate of intussusception reduction.
