Most patients diagnosed with gastroesophageal reflux disease do not show erosive lesions in the esophagus. The esophagus minimal changes, which include white, reddish, edematous and/or acanthotic disturbances, are usually not perceived during endoscopic procedure and in Japan are included as part of the non erosive reflux disease. Patients: With prior consent, subjects with symptoms of gastroesophageal reflux were included, and were compared with a group without said symptoms. Methods: Fujinon HR250 equipment was used. The endoscopy was recorded on DVD and, routinely, photographs of the gastroesophageal and the squamous columnar junctions were taken. Los Angeles classification was used, as modified by the Japanese which includes Esophagus Minimal Changes. Results: Upper digestive endoscopy was used in 146 patients: 86 men and 60 women, with ages ranging between 15 and 83, and an average of 38.71. Three groups were distinguished: I) Without changes in the esophagus; II) With erosive changes in the esophagus; and III) With esophagus minimal changes. Esophagus Minimal Changes might be reported in 53.44% and in 36.66% of patients with and without gastroesophageal reflux symptoms, respectively. Conclusion: Esophagus Minimal Changes are frequent but are unobserved if researcher does not know what the investigation must be on and if researcher does not insist in looking for them in patients with a diagnosis of Non Erosive Reflux Disease.
