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.

Changing trends in peptic ulcer prevalence in a tertiary care setting in the Philippines: a seven-year study.

Background And Aims: The declining global prevalence of peptic ulcer disease (PUD) might be because of the decreasing prevalence of Helicobacter pylori (Hp) infection. The aims of the present study were to determine the prevalence of PUD during a 7-year period and to investigate its relationship with the prevalence of Hp infection during the same period.

Methods: All upper gastrointestinal endoscopies carried out at Santo Tomas Hospital in Manila from January 1996 to December 2002 were evaluated.
