Normal Ranges of 24‐Hour pH‐metry Established in Corrected Esophageal Atresia

This study was undertaken to determine baseline values of 24‐hour pH‐metry in children who had undergone correction for esophageal atresia. A 24‐hour pH‐metry without medication was conducted in 13 patients with an uncomplicated postoperative course after correction of esophageal atresia. The pH‐metry was performed in the hospital with a flexible glass electrode. The mean reflux index was 4.08%, the mean total number of reflux periods with a pH less than 4 was 21, and the mean number of periods of pH less than 4 lasting longer than 5 minutes was 2.5. Twenty‐four‐hour pH‐metry values in asymptomatic esophageal atresia patients are the same as in children from the same age group with normal anatomy.
