高频超声对先天性肥厚性幽门狭窄的诊断(附20例分析)

The diagnosis of congenital hypertrophic pylonic stenosis by high-frequency ultrasound

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20例经手术证实的先天性肥厚性幽门狭窄的超声表现,并与X线片对照比较。结果高频超声可清晰的显示幽门的增厚程度,20例先天性肥厚性幽门狭窄超声诊断确诊率100%,X线片诊断确诊率55%。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,是其首选的影像学检查方法 。

Objective To investigale the value of high-frequency ultrasound in congenital hypertrophic pyloric stenosis. Methods The high-frequency ultrasound result for 20 cases was studied with congenital hypertrophic pyloric stenosis, and comparison was made with X-ray. Results High-frequency ultrasound could be shown pyloric modality. In 20 cases,the diag- nostic accuracy rate of ultrasound was 100%, and the diagnostic accuracy rate of X-ray was 55 %. Conclusion High-frequency ultrasound has been shown to be the most sensitive for the diagnosis of pyloric slenosis. It is an easy, reliable an safe examination method and the optimal method in diagnosis of congenital hypertrophic pyloric stenosis.
