Summary
Diagnosing non-cardiac chest pain from the esophagus remains challenging. This review compares esophageal provocation tests and 24-hour monitoring to understand acid reflux and dysmotility causes.
Area of Science:
- Gastroenterology
- Digestive System Disorders
- Esophageal Pathophysiology
Background:
- Non-cardiac chest pain (NCCP) diagnosis is complex.
- Esophageal dysfunction is a common cause of NCCP.
- Accurate diagnostic methods are crucial for effective treatment.
Purpose of the Study:
- To review the diagnostic accuracy of esophageal provocation tests for NCCP.
- To compare provocation tests with 24-hour esophageal monitoring.
- To correlate test results with underlying esophageal mechanisms.
Main Methods:
- Review of diagnostic studies on esophageal provocation tests (acid perfusion, edrophonium, balloon distension).
- Comparison with 24-hour intra-esophageal pH and pressure monitoring.
- Analysis of mechanisms: acid reflux, esophageal dysmotility, or combined.
Main Results:
- Diagnostic accuracy varies among provocation tests.
- 24-hour monitoring provides comprehensive data on reflux and motility.
- Provocation tests and monitoring offer complementary insights into NCCP origins.
Conclusions:
- No single test definitively diagnoses all esophageal causes of NCCP.
- A combination of provocative testing and 24-hour monitoring may be necessary.
- Understanding underlying mechanisms (acid reflux, dysmotility) guides therapeutic strategies.
