     【摘要】 目的 探讨高频超声显像在先天性肥厚性幽门狭窄的诊断意义。方法 应用高频及低频超声对临床疑有先天性肥厚性幽门狭窄的患儿进行超声检查。观察幽门的形态、结构并分别测量幽门肌层的厚度和长度及幽门管腔内径。结果 以空腹后胃腔扩张,幽门肌厚度≥4 mm,幽门前后径>13 mm,幽门管长度>17 mm为诊断肥厚性幽门狭窄的标准结果。所有患者均经手术证实并于手术后3~7 d呕吐症状消失,病情痊愈。结论 高频超声是先天性肥厚性幽门狭窄安全、简便、可靠的诊断方法,提高了先天性肥厚性幽门狭窄的确诊率,应是目前首选的方法。

    YANG Zi,SHI Yan.

    【Abstract】 Objective To investigate the high-frequency ultrasound imaging in congenital hypertrophic pyloric stenosis of the significance of the diagnosis.Methods High-frequency and low frequency ultrasound for clinical suspected congenital hypertrophic pyloric stenosis of the children with ultrasound.Observation of Helicobacter pylori form and structure of the pyloric muscle,respectively measuring the thickness and length and diameter of bureaucratic Helicobacter pylori.The results SO as to expand on an empty stomach after the stomach cavity,the thickness of pyloric muscle≥4 mm,pyloric diameter>13 mm,length of the tube H.>17 mm for the diagnosis of hypertrophic pyloric stenosis of the results of the standard.All patients were confirmed bysurgery and postoperative 3 to 7 days vomiting symptoms disappear,patients recover.Conclusion High-frequency ultrasound is a congenital hypertrophic pyloric stenosis safe,simple and reliable methods of diagnosis and improve the congenital hypertrophic pyloric stenosis rate of diagnosis,is the preferred method presently now. ......
