Detection of reflux-symptom association in children with esophageal atresia by video-pH-impedance study

Table 5 Parameters used and results from the analysis of combined Video Multichannel Intraluminal Impedance and pH study in children diagnosed esophageal atresia after esophageal anastomosis between using and non-using acid suppression therapy (n = 17)
