The Clinical Features and Predisposing Factors of Asymptomatic Erosive Esophagitis.

PMID 27796766


Asymptomatic erosive esophagitis (AEE) is considered an erosive esophagitis without the typical reflux symptoms, but the clinical course and significance of AEE is still unclear. We investigated the prevalence and predisposing factors of AEE, and tried to determine its clinical features and significance. Subjects, who had at least two health inspections (upper endoscopy, self-reporting questionnaire, and serum Helicobacter pylori IgG antibody test) at our center, were enrolled. The questionnaire included typical reflux symptoms, previous medical history, underlying disease, smoking, alcohol intake, and medication history. Based on the results of follow-up study, the changes in endoscopic findings and reflux symptoms were also investigated. Of the 2961 patients visiting our clinic, 568 (19.2xa0%) were diagnosed with AEE. Age over 50xa0years, male sex, a body mass index over 25, current smoking, heavy drinking, negativity for H. pylori infection, and hiatal hernia were independent predisposing factors for AEE (pxa0=xa00.020, pxa0
