Relationship between functional endoscopy and impedance-pH measurement.

Area of Science:

• Gastroenterology
• Diagnostic Medicine
• Reflux Disease Research

Background:

• Traditional diagnostic tools struggle to link extra-esophageal symptoms with pathological reflux.
• Functional endoscopy, specifically video panendoscopy (VPE), is a potential new method.
• Objective data on VPE's success in reflux diagnostics are lacking.

Purpose of the Study:

• To investigate the relationship between endoscopic findings from VPE and impedance-pH monitoring in patients with extra-esophageal reflux symptoms.
• To objectively verify the diagnostic utility of VPE in this patient group.

Main Methods:

• Video panendoscopy (VPE) was performed on patients with extra-esophageal reflux symptoms.
• Impedance-pH monitoring, the gold standard for esophageal reflux diagnostics, was conducted.
• Correlation analysis between VPE findings and impedance-pH parameters was performed.

Main Results:

• Pathological findings during VPE demonstrated a significant correlation with key impedance-pH monitoring parameters.
• Specifically, correlations were observed with the number of reflux episodes, fraction time, and DeMeester score.
• This supports the utility of VPE in assessing reflux activity.

Conclusions:

• Video panendoscopy (VPE) findings correlate objectively with impedance-pH monitoring results in patients experiencing extra-esophageal reflux symptoms.
• VPE appears to be a valuable tool for diagnosing the causal relationship between reflux and these symptoms.
• Further validation of VPE in reflux diagnostics is supported by these findings.
