The authors examined 28 children, mean age 12 months (26 days to 5 years), for a suspected gastro-esophageal reflux (GER), by two method of diagnosis: 24 hours continuous pH-monitoring and radiology. They found a first group (11 cases) with both of these methods negative; a second group (7 cases) with GER confirmed by pH-monitoring, but with negative radiology: a third group (6 cases) where both of these methods resulted positive and eventually a fourth group (4 cases) where radiology showed the presence of GER, not confirmed by pH-monitoring. The Authors conclude that continuous pH-monitoring for its accuracy, would have to be only first degree method in diagnosis of GER. In some cases the second level method is endoscopy whereas radiology is a third level one, to show associated malformations.
作者通过两种诊断方法对28名疑似胃食管反流（GER）的儿童进行了检查，这些儿童的平均年龄为12个月（26天至5岁）。这两种诊断方法分别是24小时连续pH监测和放射学检查。他们发现，第一组（11例）两种方法的检查结果均为阴性；第二组（7例）通过pH监测确诊为GER，但放射学检查结果为阴性；第三组（6例）两种方法的检查结果均为阳性；最后第四组（4例）放射学检查显示存在GER，但pH监测未证实。作者得出结论，由于连续pH监测的准确性，它应该只是GER诊断的一级方法。在某些情况下，二级方法是内窥镜检查，而放射学检查是三级方法，用于显示相关的畸形。
