The patients were divided into two groups (acid reflux and nonacid reflux) based on their MII\u2010pH monitoring data. Reflux episodes, endoscopic findings, and esophageal dynamic parameters were assessed and compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 142 patients were included (acid reflux [n = 58], nonacid reflux [n = 60], control group [n = 24]). There were more patients with esophagitis and more severe esophageal mucosal injury in the acid reflux group than in the nonacid reflux group. The acid reflux group had reduced lower esophageal sphincter (LES) basal pressure, shorter LES length, lower esophageal pressure and distal contractile integral index than the nonacid reflux group. Patients in the acid reflux group had more large breaks and a higher incidence of type II and III esophagogastric junction morphology than those in the nonacid reflux group. Acid exposure time, the incidence of long\u2010term acid reflux, recumbent acid reflux, and the incidence of acid and nonacid reflux had a significant negative correlation with esophageal body motility or LES function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study suggests that an increase in esophageal acid exposure is correlated with an increase in
