13例先天性肥厚性幽门狭窄的变频超声诊断分析

The Frequency Ultrasound Diagnosis of 13 Congenital Hypertrophic Pylonic Stenosis Cases

目的探讨变频超声诊断先天性肥厚性幽门狭窄(CHPS)的价值。方法用变频超声技术对13例CHPS患儿进行检查,测量幽门管直径、长度及幽门肌厚度,并动态观察胃腔、胃蠕动及幽门管的开放。结果 13例CHPS患儿的幽门管短轴断面直径约14.5～18.2mm,幽门管长度约17.2～22.3mm,幽门肌厚度约3.9～5.1mm。结论变频超声对CHPS的诊断具有特异性,且安全、简便,可作为首选的影像学检查方法。

Objective To investigate the diagnosis value of frequency ultrasound for the congenital hypertrophic pyloric stenosis（CHPS）. Method 13 children with CHPS were examined by frequency ultrasound including the measurement of the diameter and the length of pyloric tube and thickness of pyloric muscle, and dynamic observation of stomach, gastric motility and pyloric opening. Results The short-axis cross-section diameter of pyloric tube are about 14.5 - 18.2ram of 13 children with CHPS, the length are about 17.2-22.3mm, and the thickness of pylofic muscle are about 3.9-5.1mm. Conclusion The frequency ultrasound can be used as the preferred imaging method for the diagnosis of CHPS, which is specific, safe, and simple.
