高频超声与低频超声联合检查诊断小儿肠套叠的价值

Value of Combined Examination of High Frequency Ultrasound and Low Frequency Ultrasound in Diagnosis of Intussusception in Children

目的:分析高频超声与低频超声联合检查诊断小儿肠套叠的价值。方法:选取2021年1月~2023年4月本院收治的83例疑似小儿肠套叠患儿,所有患儿均接受高频超声、低频超声检查,参考X线空气灌肠检查结果,分析不同检查方式准确率。结果:83例疑似小儿肠套叠患儿经低频超声检查53例为真阳性,19例为真阴性,经高频、低频超声联合检查,60例为真阳性,22例为真阴性;低频超声单独检查和高频超声与低频超声联合检查误诊率、特异度对比无明显差异(P>0.05),高频超声与低频超声联合检查准确度、灵敏度明显比低频超声单独检查高(P<0.05),漏诊率比低频超声单独检查低(P<0.05)。结论:小儿肠套叠应用高频超声与低频超声联合检查,可以更准确地对患儿病情进行诊断,避免漏诊、误诊。

Objective:To analyze the value of combined high-frequency ultrasound and low-frequency ultrasound in the diagnosis of intussusception in children.Methods:83 cases of suspected intussusception in children admitted to our hospital from January 2021 to April 2023 were selected.All children were examined by high-frequency ultrasound and low-frequency ultrasound.The accuracy of different examination methods was analyzed by referring to the results of X-ray air enema examination.Results:Of 83 suspected children with intussusception,53 cases were true positive and 19 cases were true negative by low frequency ultrasonography,60 cases were true positive and 22 cases were true negative by high frequency ultrasonography and low frequency ultrasonography.There was no significant difference in the misdiagnosis rate and specificity between the single examination of low frequency ultrasound and the combined examination of high frequency ultrasound and low frequency ultrasound(P>0.05).The accuracy and sensitivity of the combined examination of high frequency ultrasound and low frequency ultrasound were significantly higher than that of the single examination of low frequency ultrasound(P<0.05),and the missed diagnosis rate was lower than that of the single examination of low frequency ultrasound(P<0.05).Conclusion:The combined examination of high frequency ultrasound and low frequency ultrasound in children with intussusception can more accurately diagnose the disease of children and avoid missing diagnosis and misdiagnosis.
