Forty infants with suspected gastroesophageal reflux (GOR) underwent continuous 24 hour esophageal pH-metry and sonography of the gastroesophageal junction. In 29 out of 40 cases (72.5%) GOR was confirmed by the 24 hour pH-monitoring, because of a percentage of total time of reflux of 10% or more. The positive and negative predictive value of sonography versus the result of continuous 24 hour pH-monitoring was 80% and 50% respectively. Sonography cannot be considered a faithful diagnostic tool in screening for GOR in infants.
40名疑似胃食管反流（GOR）的婴儿接受了24小时食管pH值连续监测以及胃食管交界处的超声检查。40例中有29例（72.5%）通过24小时pH值监测确诊为胃食管反流，因为反流总时间百分比达到或超过10%。超声检查相对于24小时连续pH值监测结果的阳性预测值和阴性预测值分别为80%和50%。在筛查婴儿胃食管反流方面，超声检查不能被视为可靠的诊断工具。
