摘　　要：目的 探讨高频超声动态检查法对先天性肥厚性幽门狭窄（CHPS）的超声诊断价值.方法 总结60例经手术证实的 CHPS 患儿的高频超声图像特征及检查方法.检查前患儿饮水100～150 ml,以高频探头（6～10 MHz）经腹部扫查,测量幽门直径、肌层厚度、长度并结合动态观察胃腔内液体通过幽门管状况,综合分析诊断CHPS.结果 CHPS患儿幽门直径 （14.9 ±2.54） mm,范围10.3～19.5 mm;肌层厚度 （4.93 ±0.87） mm,范围3.5～6.8 mm;幽门长度平均为（19.8 ±3.73） mm,范围16.4～23.6 mm.超声测量的CHPS 患儿幽门直径、肌层厚度和幽门长度与手术中测量无显著性差异（P＞0.05）.8例症状不典型、右上腹未触及明显包块的CHPS患儿应用动态方法作出了明确诊断.超声明确观察到胃壁不规律的收缩活动及胃内液体通过幽门受阻情况.结论 高频超声动态观察是先天性肥厚性幽门狭窄安全、简便、可靠的诊断方法,具有很好的临床应用价值.Objective To explore the value of using high-frequency ultrasound in diagnosing congenital hypertrophical pyloric stenosis （CHPS）. Methods The high-frequency ultrasound features of 60 cases of CHPS and the examination methods were reviewed. 100-150 ml of water was given to patients before examination. The pyloric diameter, the length and the thickness of pyloric muscle were measured dynamically by the high-frequency （6-10 MHz） ultrasound in all cases of CHPS. Results The pyloric diameter was （14.9±2.54）mm with a range of 16.4-23.6mm, the muscle thickness was （4.93±0.87） mm with a range of 3.5-6.8mm, and pyloric length was （19.8 ± 3.37）mm with a range of 16.4-23.6mm. There was no significant difference in the above parameters （ P 〉0.05）. 8 cases without typical symptoms were confirmed by the above method. Conclusion High-frequency ultrasound can be used effectively, safely and conveniently to diagnose CHPS.
