Evaluating pH-impedance tracings for GERD classification

Official title: Prospective Evaluation of PH-impedance Tracings According to the Wingate Consensus, and Influence on Gastro-oesophageal Reflux Disease (GERD) Classification According to the Lyon Consensus.

Run by Universitair Ziekenhuis Brussel · NCT06084572 · Data updated 2026-11-12

This study is testing how pH-impedance tracings can help better classify gastroesophageal reflux disease (GERD) in patients by looking at why some reflux episodes are ignored and considering factors like symptom severity and medication use.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 80 who have undergone pH-MII testing without the influence of PPIs.

Probably not a fit

Patients with prior upper GI endoscopy indicating structural disease or those who have undergone gastric surgery may not benefit from this study.

What this trial studies

This observational study aims to prospectively evaluate pH-impedance tracings in patients with gastroesophageal reflux disease (GERD) by categorizing reasons for discarding reflux episodes identified through automated analysis. The study will manually review these tracings according to the Wingate consensus and assess their impact on GERD classification based on the Lyon consensus. Additionally, it will explore potential confounders such as symptom severity and the use of proton pump inhibitors (PPIs) during the pH-MII procedure.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of GERD classification and improve patient management strategies.

How similar studies have gone: Previous studies have shown promise in improving GERD diagnosis through similar methodologies, but this specific approach is relatively novel.
