摘　　要：目的 回顾分析应用高频超声对先天性肥厚性幽门狭窄进行检测的结果 与X线造影检查结果 对照,以探讨高频超声检查与X线造影在先天性肥厚性幽门狭窄诊断中的应用价值.方法 对33例X线造影下诊断为肥厚性幽门狭窄的患儿进行高频超声检查,测量幽门管各径线,观察胃腔情况,并与X线造影结果 进行对照、分析.结果 1例X线造影检查疑似肥厚性幽门狭窄病例,经超声检查后排除;其余32例高频超声诊断为肥厚性幽门狭窄的病例均经胃镜检查证实.高频超声测得幽门管长度为20.3±3.31mm,X线造影下测得16.2±3.68mm,与胃镜下测量相比较,超声下测量较为准确,X造影下测得的幽门管较短.结论 高频超声可作为先天性肥厚性幽门狭窄诊断的首选筛查方法 .Objective To retrospectively analyse examination results by high-frequency ultrasound and contrast radiography for congenital hypertrophic pyloric stenosis （CHPS） , and to explore clinical values of uhrasonography and contrast radiography in diagnosis of the disease. Methods 33 children diagnosed as CHPS by contrast radiography received high-frequency ultrasound examination again, diameters of pyloric canal were measured and stomach cavity was observed. The results of the children with CHPS by high-frequency ultrasound examination were compared with those of the children by contrast radiography. Results The diagnosis of 1 child suspected as CHPS by contrast radiography was excluded after high-frequency ultrasound examination, and the diagnoses of remaining 32 children diagnosed as CHPS by high-frequency ultrasound examination were confirmed by gastroscopy. The length of the polyric canal of the children with CHPS measured by high-frequency ultrasound examination was 20.3 ± 3.3hnm, while that by contrast radiography was 16.2 ± 3.68ram, as compared with that by gastroscopy, the result by high-requency ultrasound examination was more accurate than that by contrast radiography （that by the latter was shorter）. Conclusion High-frequency ultrasound examination can be used as the first-chosen method to diagnose CHPS.
