  [摘  要] 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29 mm~42 mm(均值35 mm),长度65 mm~81 mm(均值75 mm);高频B超确诊141例,套叠肠段最大外径39 mm(均值33.3 mm),最大长度72 mm,(均值71.5 mm)。11例小肠套叠,低频B超确诊1例,套叠段外径26 mm,长度51 mm;高频B超确诊10例,套叠肠段最大外径19 mm(均值16.6 mm),最大长度40 mm(均值23.4 mm)。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

  Abstract: 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 highfrequency ultrasound imaging and the outside diameter and length of intussusception were determined.Results 38 of l69 large intestine cases were definitely diagnosed with lowfrequency 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 highfrequency 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 lowfrequency ultrasound imaging,The outside diameter 26 mm,and the lenth 51 mm.In 10 enteric intussuscepyion cases diagnosed by highfrequency ultrasound imaging,the maximum outside 19 mm(mean 16.6 mm),the maximum lenth 40 mm(mean 23.4 mm).Conclusions Highfrequency ultrasound imaging may more significantly increase detection rate of intestines intussusception than lowfrequency ultrasound imaging.

    肠套叠是小儿肠梗阻的常见原因,80%发生于2岁以下的儿童。目前,国内对小儿肠套叠的诊断多采用X线透视下空气灌肠检查,超声学检查,尤其高频超声检查在小儿肠套叠中的诊断价值报道较少[1]。

  收集我院自2000年8月至今采用超声检查确诊的小儿肠套叠病例180例,现分析报告如下。

  1  资料与方法

  1.1  一般资料 

  本组180例,男88例,女92例,年龄6个月~9岁,平均11个月。患儿均有阵发哭闹、不安,伴有或不伴有呕吐,少数伴有果酱样血便,腹部可触及包块133例。

  1.2  方法 

  采用ALT-5000彩超仪。探头频率3.5 MHz~5 MHz(低频探头)、7 MHz~10 MHz(高频探头)。首先采用低频探头行腹部检查,随后换用高频探头行病区的探察,测量套叠肠段外径及套入长度。
