In 17 infants with hypertrophic pyloric stenosis, the pyloric diameter was measured preoperatively by ultrasound. The mean pyloric diameter was 15.12 +/- 2.11 mm (mean +/- SD), range 11 to 19 mm. During pyloromyotomy, the hypertrophic pylorus was precisely measured craniocaudally and dorsoventrally, and measurements were obtained concerning muscular thickness and length of the pylorus. The preoperative and intraoperative measurements were subsequently compared. Differences of 0.76 +/- 1.68 mm and 1.24 +/- 2.04 mm were found for the dorsoventral and craniocaudal diameters, respectively. The intraoperative measurements were consistently greater than the sonographic findings. The length of the pylorus averaged 22.0 +/- 2.66 mm, the muscular thickness 6.53 +/- 1.68 mm, respectively. This prospective study confirms the diagnostic value of sonography in congenital hypertrophic pyloric stenosis.
对17例肥厚性幽门狭窄婴儿在术前通过超声测量幽门直径。平均幽门直径为15.12±2.11毫米（平均值±标准差），范围为11至19毫米。在幽门肌切开术中，对肥厚的幽门进行精确的头尾方向和背腹方向测量，并获取有关幽门肌肉厚度和长度的测量值。随后比较术前和术中测量值。发现背腹直径和头尾直径的差异分别为0.76±1.68毫米和1.24±2.04毫米。术中测量值始终大于超声检查结果。幽门长度平均为22.0±2.66毫米，肌肉厚度分别为6.53±1.68毫米。这项前瞻性研究证实了超声检查在先天性肥厚性幽门狭窄中的诊断价值。
