摘要
目的:探讨高频彩色多普勒超声在诊断小儿肠套叠中的临床价值。方法:选取2017年7月-2019年7月收治的100例急腹症患儿作为研究对象,经空气灌肠及手术确诊为肠套叠共75例,且所有患儿均行普通低频超声和高频彩色多普勒超声检查,观察高频彩色多普勒超声和普通低频超声检查诊断小儿肠套叠的阳性预测值、阴性预测值、确诊率、敏感度、特异度、确诊率、误诊率及漏诊率。结果:100例急腹症患儿经高频彩色多普勒超声检查后肠套叠阳性72例,阳性预测值为97.30%;阴性例数为23例,阴性预测值为88.46%,100例急腹症患儿经普通低频超声检查后肠套叠阳性例数为57例,阳性预测值为78.08%;阴性例数为9例,阴性预测值为33.33%;高频彩色多普勒超声诊断小儿肠套叠的敏感度96.00%、特异度92.00%、确诊率95.00%,均高于普通低频超声的76.00%、36.00%、66.00%(P<0.05);高频彩色多普勒超声诊断的误诊率8.00%、漏诊率4.00%,低于普通低频超声的64.00%、24.00%(P<0.05)。结论:高频彩色多普勒超声用于小儿肠套叠诊断中具有较高的临床价值,不仅具有较高敏感度、特异度、确诊率,并且漏诊率及误诊率低,能够为疾病诊治提供客观依据,值得应用及推广。
Objective:To investigate the clinical value of high frequency color Doppler ultrasound in the diagnosis of intussusception in children.Method:From July 2017 to July 2019,100 cases of children with acute abdomen were selected as the research object.75 cases were diagnosed as intussusception by air enema and operation.All children were examined by ordinary low-frequency ultrasound and high-frequency color Doppler ultrasound.The positive predictive value,negative predictive value and diagnosis of intussusception in children diagnosed by high-frequency color Doppler ultrasound and ordinary low-frequency ultrasound were observed Rate,sensitivity,specificity,diagnosis rate,misdiagnosis rate and missed diagnosis rate.Result:In 100 cases of acute abdomen,72 cases were positive with positive predictive value of 97.30%;23 cases were negative with negative predictive value of 88.46%,of which the diagnosis rate was 95.00%.In 100 cases of acute abdomen,the number of positive cases was 57 cases,the positive predictive value was 78.08%,the number of negative cases was 9 cases,and the negative predictive value was 33.33%.The sensitivity,specificity and diagnosis rate of high-frequency color Doppler ultrasound in the diagnosis of infantile intussusception were 96.00%,92.00% and 95.00%,respectively,which were higher than 76.00%,36.00% and 66.00% of ordinary low-frequency ultrasound (P<0.05).The misdiagnosis rate and missed diagnosis rate of high-frequency color Doppler ultrasound diagnosis were 8.00% and 4.00% respectively,which were lower than those of 64.00% and 24.00% of ordinary low-frequency ultrasound (P<0.05).Conclusion:High frequency color Doppler ultrasound in the diagnosis of infantile intussusception has high clinical value,not only has high sensitivity,specificity,diagnosis rate,but also has low rate of missed diagnosis and misdiagnosis.It can provide objective basis for the diagnosis and treatment of diseases,and is worthy of application and promotion.
