ABSTRACTIntroduction: failed anti-reflux barrier allows the development of gastroesophageal reflux disease. The motility factors making up the anti-reflux barrier may be studied through the esophageal manometry.
Objective: to characterize motility factors in patients with erosive esophagitis by means of developed software and technologies.
Methods: a descriptive cross-sectional study was carried out in patients with erosive esophagitis by analyzing the motility factors through esophageal manometry.
Results: the resulting pattern showed unstable and hypotonic lower esophageal sphincter, significant frequency of hiatal hernia and severe esophageal motor disorders.
Conclusions: the main damage observed in the anti-reflux barrier occurs from the mildest degrees of the disease, without real association between this one and the degree of erosive esophagitis. The significant effect on peristalsis may be one of the elements leading to the onset of the disease.
