先天性肥厚性幽门狭窄高频超声诊断价值

The Diagnosis Value of High Frequency Ultrasound for Congenital Hypertrophic Pyloric Stenosis

目的:探讨高频超声对先天性肥厚性幽门狭窄的诊断价值。方法:分析32例经手术证实的先天性肥厚性幽门狭窄的患儿高频超声表现,测量幽门肌层厚度、幽门管长度及幽门管直径,并与术中的测量值比较。结果:高频超声可清晰的显示幽门的形态、幽门肌增厚的程度,幽门肌超声测量值与术中的测量值比较差异无统计学意义(P>0.05)。结论:高频超声检查对先天性肥厚性幽门狭窄有较强的特异性,安全、简单易行,可作为先天性肥厚性幽门狭窄诊断的首选影像学检查方法。

Objective.. To investigale the value of high frequency ultrasound in congenital hypertrophic pyloric stenosis. Methods.. Analyze the high frequency ultrasound results for 32 cases with congenital hypertrophic pyloric stenosis, which were confirmed by surgery, to measure pyloric muscle wall thickness, pyloric channel length and pyloric muscle diameter,and the data were compared with that of surgery findings. Results： High-frequecy ultrasound could be shown pyloric modality and the sign of the hypertrophied pyloric muscles bulging into the gastric lumen. There was no significant difference between the thickness of pyloric muscle and the value found in surgery. Conclusion： High-frequency ultrasound has been shown to be the most sensitive for the diagnosis of pyloric stenosis. It can be used effective, safe and convenient to diagnose congenital hypertrophic pyloric stenosis. High-frequency ultrasound is the optimal method in diagnosis of congenital hypertrophic pyloric stenosis.
