Abdominal ultrasonic examination was performed in 8 infants with hypertrophic pyloric stenosis, and in 23 control patients of the same age. The average anteroposterior diameter of the pylorus in children with hypertrophic pyloric stenosis measured 17 mm (range 15-20 mm), and 9.6 mm (range 6-12 mm) in the control group. The statistical difference was highly significant (p less than 0.001). In addition, delayed gastric emptying and retroperistalsis of the stomach were demonstrated. The sonographic findings of hypertrophied pylorus correlated well with roentgenologic results and were confirmed during following operation. Abdominal sonography is a rapid, safe and non-invasive method for the identification of hypertrophic pyloric stenosis.
对8例肥厚性幽门狭窄婴儿及23例同龄对照患儿进行了腹部超声检查。肥厚性幽门狭窄患儿幽门前后径平均为17mm（范围15 - 20mm），对照组为9.6mm（范围6 - 12mm）。统计学差异极显著（p小于0.001）。此外，还显示出胃排空延迟和胃逆蠕动。肥厚幽门的超声检查结果与X线检查结果相关性良好，并在随后的手术中得到证实。腹部超声检查是一种快速、安全且无创的识别肥厚性幽门狭窄的方法。
