초록
목 적: 위식도 역류 질환 환아에서 이중 채널 24시간 식도 pH 측정 검사의 유용성을 평가하고 식도 원위부와 근위부에서 얻은 식도 pH 검사 계측치를 비교 평가하고자 본 연구를 하였다. 대상 및 방법: 1997년 7월부터 1998년 12월까지 조선의대 병원 소아과에서 식도역류가 의심되어 내원한 환아 46명을 대상으로 18~24시간 동안 식도의 상부와 하부 두 부위에서 동시에 식도 pH를 측정하였다. 병적 역류의 기준은 95백분위수 이상의 역류지표를 병적 역류로 정의하였다. 결 과: 1) 원위부 병적 위식도역류를 보인 환자군(group I)은 24명으로 평균연령이
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 (group I); 22 patients with normal distal reflux (group II). 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.
