Esophageal function tests diagnose mechanical or functional disorders, including gastroesophageal reflux disease (GERD). The barium esophagogram is key, while pH monitoring aids atypical GERD diagnosis.

Area of Science:

Gastroenterology
Digestive System Disorders
Diagnostic Imaging

Background:

Esophageal disorders stem from mechanical or functional issues.
Gastroesophageal reflux disease (GERD) is prevalent and can manifest atypically.
Esophageal function tests categorize into anatomic and functional studies.

Purpose of the Study:

To review diagnostic modalities for esophageal disorders.
To highlight the role of various tests in evaluating esophageal function and GERD.
To emphasize the diagnostic utility of prolonged ambulatory esophageal pH monitoring for atypical GERD.

Main Methods:

Barium esophagogram: Assesses oropharyngeal/esophageal anatomy, motility, and GERD.
Endoscopy: Enables direct visualization and tissue sampling.

Esophageal scintigraphy and manometry: Complementary functional studies.

Ambulatory esophageal pH monitoring: Prolonged monitoring for GERD diagnosis.

Main Results:

The barium esophagogram is crucial for comprehensive esophageal evaluation.
Endoscopy provides direct inspection and biopsy capabilities.
Ambulatory pH monitoring significantly aids in diagnosing atypical GERD presentations.
Esophageal scintigraphy and manometry offer specific functional insights.

Conclusions:

A range of tests are available for diagnosing esophageal disorders.
The barium esophagogram offers broad anatomical and functional assessment.
Ambulatory esophageal pH monitoring is vital for atypical GERD diagnosis, improving patient outcomes.
