[Reflux esophagitis--diagnosis and differential diagnosis]

Area of Science:

• Gastroenterology
• Digestive Health
• Esophageal Disorders

Context:

• Gastroesophageal reflux disease (GORD) presents with typical symptoms like heartburn and regurgitation.
• Atypical symptoms include dysphagia, odynophagia, pharyngitis, reflux-induced pulmonary issues, and chest pain.
• Endoscopic findings for GORD range from mucosal reddening and erosions to ulcers and strictures.

Purpose:

• To outline the diagnostic criteria for gastroesophageal reflux disease (GORD).
• To differentiate between typical and atypical GORD presentations.
• To establish when diagnostic procedures are necessary for GORD.

Summary:

• Typical GORD symptoms (heartburn, regurgitation) may not require further investigation.
• Atypical GORD symptoms necessitate endoscopic evaluation for diagnosis.
• Endoscopic signs include mucosal changes, erosions, ulcers, strictures, and Barrett's esophagus (columnar epithelial metaplasia).

Impact:

• Guides clinical decision-making in diagnosing GORD.
• Highlights the importance of endoscopy for atypical presentations.
• Improves patient management by differentiating treatable symptoms from those requiring further diagnostics.
