Analysis on the clinical and endoscopic parameters in 1247 patients with reflux esophagitis

Aim: To summarize and analyze the clinical and endoscopic parameters in patients with reflux esophagitis(RE). Methods:1247 patients with RE were diagnosed in our hospital endoscopy center from September 2010 to August 2012. The general information of the patients and the relationship between endoscopic classification and concomitant diseases were analyzed. Results: According to the endoscopic findings, 1247 subjects (4.70%) were found to have RE:932 (74.74%) males and 315 (25.26%) females, and the male to female ratio was 2.96:1. The peak age of prevalence was 50 to 59 (27.35%) which is followed by 40 to 49 (23.10%). In this study, most of the patients had a mild degree of esophagitis representing LA-A in 60.63% and LA-B in 34.24%. The antrum hyperemia was found in 291 patients with esophagitis (23.34%), followed by antrum erosion (20.13%) and hatal hernia (15.88%). There is no statistically significant relevance between Helicobacter pylori infection and RE (P > 0.05), but Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors, a history of gastroesophageal surgery and antrum hyperemia were found to be associated with RE (P < 0.05). Conclusion: The prevalence rate of endoscopic RE in our study was 4.70%, and most patients had a mild grade esophagitis. Male, advanced age, Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors and a history of gastroesophageal surgery are the risk factors of esophagitis. Antrum hyperemia may reduce the severity of RE.
