Reflux esophagitis and its relationship to hiatal hernia

Area of Science:

• Gastroenterology
• Endoscopy
• Digestive Diseases

Background:

• Gastrointestinal symptoms frequently lead to upper gastrointestinal endoscopy referrals.
• Understanding the prevalence of conditions like reflux esophagitis and hiatal hernia is crucial for patient management.
• Previous studies suggest varying prevalence rates of these conditions globally.

Purpose of the Study:

• To determine the prevalence of reflux esophagitis and/or hiatal hernia in patients referred for endoscopy.
• To investigate the relationship between endoscopic findings of reflux esophagitis and the presence of hiatal hernia.
• To compare prevalence rates with peptic ulcer disease and Western country reports.

Main Methods:

• A retrospective study of 1,010 patients undergoing upper gastrointestinal endoscopy.
• Data collected from September 1994 to March 1996 at Yong Dong Severance Hospital.
• Hiatal hernia defined as gastric mucosa extension ≥2 cm above the diaphragmatic hiatus.

Main Results:

• Reflux esophagitis prevalence: 5.3%; hiatal hernia: 4.1%; duodenal ulcer: 7.2%; gastric ulcer: 8.2%.
• Higher prevalence rates of reflux esophagitis and hiatal hernia observed in males compared to females.
• Thirty-two percent of patients with reflux esophagitis also had a hiatal hernia (p<0.01).

Conclusions:

• A significant association exists between reflux esophagitis and hiatal hernia.
• Prevalence of reflux esophagitis and/or hiatal hernia in this cohort was lower than peptic ulcer disease and Western reports.
• The findings highlight the importance of considering hiatal hernia in patients diagnosed with reflux esophagitis.
