Thirty-six infants with pyloric stenosis were studied preoperatively by ultrasound and compared with a control group of 24 normal infants aged one month. Measurement of pyloric muscle diameter and muscle wall thickness was significantly different for each measure between groups and they had a nonoverlapping distribution. Ultrasound has a clear place in the diagnosis of pyloric stenosis.
对36例患有幽门狭窄的婴儿进行了术前超声检查，并与24例1个月大的正常婴儿对照组进行了比较。两组之间幽门肌直径和肌壁厚度的测量值在每项测量中均存在显著差异，且分布不重叠。超声在幽门狭窄的诊断中具有明确的作用。
