To date, we have reported the significance of assessing the waveform pattern in multichannel intraluminal impedance-pH (MII-pH) for esophageal diseases. This study aimed to assess the relevance of MII-pH and endoscopic findings in EA. The study population of this retrospective study included 22 EA patients (median age: 3.0\u00a0years, interquartile 2\u20135\u00a0years) in whom MII-pH was conducted. Low baseline impedance values have been detected in patients with esophagitis and esophageal motility disorders. In the MII-pH study, low impedance influenced the difficulty of the analysis. We classified MII-pH waveforms according to the difficulty of analysis as either easy-to-analyze waveforms or difficult-to-analyze waveforms. With regard to waveform pattern, pH index, bolus exposure index, total reflux episodes, total proximal episodes, and acid proximal episodes in patients with difficult-to-analyze waveforms were significantly higher than in patients with easy-to-analyze waveforms. In addition, the baseline impedance values of distal esophagus in patients with difficult-to-analyze waveforms were significantly lower than in patients with easy-to-analyze waveforms. Four patients (26.7%) with a pH index \u22653.0% were diagnosed with nonerosive reflux disease. Endoscopic findings showed no erosions in EA patients with easy-to-analyze waveforms. Three patients with type A EA were difficult-to-analyze waveforms. The present study demonstrated that MII-pH is useful for evaluating EA. In particular, MII-pH can be used to detect nonerosive reflux disease. Evaluation of the waveform could be an indication for endoscopy.<\/jats:p>","DOI":"10.1093\/dote\/doag008","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T12:27:27Z","timestamp":1768912047000},"source":"Crossref","is-referenced-by-count":0,"title":["Postoperative
