[摘 要] 目的:探討高頻超聲顯像在小兒腸套疊中的意義。方法:采用低頻及高頻超聲顯像對臨床可疑腸套疊患者進行檢查,測量大腸或小腸套疊的外徑及長度。結果:169例小兒大腸套疊,低頻B超確診28例,套疊腸段外徑29 mm~42 mm(均值35 mm),長度65 mm~81 mm(均值75 mm);高頻B超確診141例,套疊腸段最大外徑39 mm(均值33.3 mm),最大長度72 mm,(均值71.5 mm)。11例小腸套疊,低頻B超確診1例,套疊段外徑26 mm,長度51 mm;高頻B超確診10例,套疊腸段最大外徑19 mm(均值16.6 mm),最大長度40 mm(均值23.4 mm)。結論:高頻超聲顯像比低頻超聲對診斷腸套疊的確診有明顯提高。
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.

腸套疊是小兒腸梗阻的常見原因,80%發生于2歲以下的兒童。目前,國內對小兒腸套疊的診斷多采用X線透視下空氣灌腸檢查,超聲學檢查,尤其高頻超聲檢查在小兒腸套疊中的診斷價值報道較少[1]。
收集我院自2000年8月至今采用超聲檢查確診的小兒腸套疊病例180例,現分析報告如下。
1 資料與方法
1.1 一般資料
本組180例,男88例,女92例,年齡6個月~9歲,平均11個月。患兒均有陣發哭鬧、不安,伴有或不伴有嘔吐,少數伴有果醬樣血便,腹部可觸及包塊133例。
1.2 方法
采用ALT-5000彩超儀。探頭頻率3.5 MHz~5 MHz(低頻探頭)、7 MHz~10 MHz(高頻探頭)。首先采用低頻探頭行腹部檢查,隨后換用高頻探頭行病區的探察,測量套疊腸段外徑及套入長度。
