초록

Background: Gastroesophageal reflux is a commonly encountered condition, but detailed data on reflux symptoms in Asian countries are lacking. Goals: To evaluate the prevalence and to document the clinical spectrum of endoscopic reflux esophagitis (RE). Study: A total 25,536 subjects underwent an upper gastrointestinal endoscopic examination as part of a health check, and completed a gastroesophageal reflux questionnaire. Endoscopic findings classified according to the Los Angeles (LA) classification and the data from gastroesophageal reflux questionnaire were analyzed. Results: On the basis of endoscopic findings, 2019 subjects (7.91%) were found to have RE: 5.87% in LA-A; 1.84% in LA-B; 0.18% in LA-C; and 0.02% in LA-D. Heartburn. acid regurgitation, chest pain, hoarseness, globus sensation. Cough, and epigastric soreness were found to be associated with RE (P < 0.05). Heartburn. acid regurgitation, and epigastric soreness were more frequent in LA-B than in LA-A (P < 0.05). Epigastric soreness was most bothersome in LA-A and LA-B, and acid regurgitation was most bothersome in LA-C and LA-D (P<0.01). Heartburn. hoarseness, and globus sensation were more frequent in men with RE, and acid regurgitation was most common in women. Conclusions: The prevalence of RE was found to be 7.91% in Korea, and the Profiles of reflux symptoms were found to depend on grade of RE and sex.
