Endoscopic evaluation of gastroesophageal sphincter dysfunction.

Area of Science:

• Gastroenterology
• Endoscopic diagnostics

Background:

• Modern endoscopy, light sources, and cameras enhance the diagnosis of reflux esophagitis.
• Objective diagnosis relies on identifying active erosion, friability, and ulceration.

Purpose of the Study:

• To outline the diagnostic capabilities of endoscopy for reflux esophagitis.
• To highlight key endoscopic findings and diagnostic considerations.

Main Methods:

• Endoscopic examination for visual signs of esophagitis.
• Correlation of endoscopic findings with hiatal hernia diagnosis.
• Consideration of infectious causes and use of biopsy/cytology.

Main Results:

• Active erosion, friability, and ulceration are reliable indicators of reflux esophagitis.
• Patulous cardia may suggest reflux, and gross reflux is pathognomonic.
• Endoscopic and x-ray diagnoses of hiatal hernia correlate well.

Conclusions:

• Endoscopy is crucial for diagnosing reflux esophagitis, with specific visual markers.
• Awareness of rare infectious causes and the role of biopsy in chronic cases is important.
• Biopsy aids in differentiating benign from malignant esophageal lesions.
