Abstract

Purpose : The aim of this study was to determine how much acid exposure would
occur in the proximal esophagus, both in normal and in patients with abnormal distal
esophageal acid exposure.
Methods : Fourty-six patients with suspected GER were classified into two groups, 24
patients with pathological distal reflux(groupⅠ); 22 patients with normal distal
reflux(groupⅡ). The ambulatory dual-probe esophageal pH monitoring was performed
for 18-24hr. The abnormal reflux was defined when the percent of time that pH was
below 4.0 exceeded the 95th percentile of normal value.
Results : The siginficant differences between distal and proximal esophageal pH
recordings in group I persisted for all parameters except for the longest episode, but
didn’t persist in group Ⅱ. At the distal esophageal site, the median percent time with
pH<4.0 in group I was 19.3 and significantly higher than at proximal site. Half of
patients with pathological distal reflux also had proximal acid reflux. Correlation
coefficients between the distal and proximal esophageal sites in group I of the number
of reflux episodes and time of the longest episode were 0.451 and 0.646 respectively.
Conclusion : The 50 percent of patients with pathological distal acid reflux also had
abnormal acid exposure in the proximal esophageal site. Therefore, we recommand
simultaneous pH recordings from dual probe esophageal sites in children with
gastroesophageal reflux.
