超声诊断先天性幽门肥厚性狭窄的临床应用

Clinical Applications of Ultrasound in the Diagnosis of Congenital Hypertrophic Pyloric Stenosis

目的探讨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≥4mm,幽门前后径≥14mm,幽门管长度≥16mm为诊断肥厚性幽门狭窄的标准。所有患者均经手术证实并于手术后3～7d呕吐症状消失,病情痊愈。结论应用超声诊断先天性肥厚性幽门狭窄可为临床提供方便快捷、准确可靠的手术依据,明显优于X线钡餐造影,可作为常规首选检查手段。

Objective To investigale the value of diagnosis for frequency ultrasound in congenital hypertrophic pyloric stenosis. Methods Examine the infants of congenital hypertrophic pyloric stenosis by Ultrasound. Observe the morphological structure of pylorus, analyze the frequency ultrasound results for the cases with congenital hypertrophic pyloric stenosis, measure the pyloric muscle wall thickness and the pyloric channel length and pyloric muscle diameter by ultrasound. Results For standard in the thickness of Pyloric musle≥4mm, the Pylorus diameter≥14mm, the length of Pylorus tube≥16mm after Stomach distention by fasting to diagnose congenital hypertrophic pyloric stenosis, all patients were confirmed by Intraoperative see and recoveryed by the Vomiting symptoms disappeared after 3-7days. Conclusion Ultrasound has been shown to be sensitive and convenient for the diagnosis and surgery basis of pyloric stenosis. It is better than Barium imaging. Utrasound is the optimal method in diagnosis of congenital hypertrophic pyloric stenosis.
