高频超声显像在小儿肠套叠中的诊断价值

目的:探讨高频超声显像在小儿肠套叠中的意义。方法:采用低频及高频超声显像对临床可疑肠套叠患者进行检查,测量大肠或小肠套叠的外径及长度。结果:169例小儿大肠套叠,低频B超确诊28例,套叠肠段外径29mm~42mm(均值35mm),长度65mm~81mm(均值75mm);高频B超确诊141例,套叠肠段最大外径39mm(均值33.3mm),最大长度72mm,(均值71.5mm)。11例小肠套叠,低频B超确诊1例,套叠段外径26mm,长度51mm;高频B超确诊10例,套叠肠段最大外径19mm(均值16.6mm),最大长度40mm(均值23.4mm)。结论:高频超声显像比低频超声对诊断肠套叠的确诊有明显提高。

Value of High Frequency Ultrasound to Diagnose Children Intestines Intussusception

Objective To discuss the clinic value of high frequency ultrasound to diagnose children intestines intussusception.Methods All patients with cilinically suspected intestines intussusception were examinated high-frequency ultrasound imaging and the outside diameter and length of intussusception were determined.Results 38 of l69 large intestine cases were definitely diagnosed with low-frequency ultrasound imaging.The outside diameter of intussusception in 38 were 29 mm~42 mm(mean 35 mm),and the lenth 65 mm~81 mm(mean 75 mm).In 141 cases diagnosed with high-frequency ultrasound imaging,the maximum outside 39 mm(mean 33.3 mm),the maximum lenth 72 mm,(mean 71.5 mm).In 1 of 11 enteric intussuscepyion cases diagnosed by low-frequency ultrasound imaging,The outside diameter 26 mm,and the lenth 51 mm.In 10 enteric intussuscepyion cases diagnosed by high-frequency ultrasound imaging,the maximum outside 19 mm(mean 16.6 mm),the maximum lenth 40 mm(mean 23.4 mm).Conclusions High-frequency ultrasound imaging may more significantly increase detection rate of intestines intussusception than low-frequency ultrasound imaging.
