Erosive esophagitis in the Philippines: a comparison between two time periods.

Background: In Asia, the incidence of gastroesophageal reflux disease diagnosed through endoscopy has increased from 3-9% to 14-16% in the last decade. The aim of this study was to determine the prevalence of erosive esophagitis (EE) over a span of 10 years in a tertiary care facility in the Philippines.

Methods: All patients diagnosed with EE from 1994 to 1997 (period A) and from 2000 to 2003 (period B) were included in the study.
