Background & Aims pH-impedance monitoring detects acid and nonacid reflux events, but
little is known about which parameters predict outcomes of different management strategies …

RESULTS One hundred fifty patients were included, 102 women (mean age 52±14 yr, range
16–84). Among the 79 patients off PPI, five did not report any symptom during the recording …

OBJECTIVES: pH-impedance testing detects reflux events irrespective of pH, but its value in
predicting treatment outcome is unclear. We prospectively evaluated subjects treated …

BACKGROUND In patients with proton pump inhibitor (PPI)-resistant symptoms, ambulatory
24-h pH-impedance monitoring can be used to assess whether a relationship exists …

Classical techniques like endoscopy and esophageal pH-metry are routinely used to study
patients with symptoms related to gastroesophageal reflux disease (GERD). Although these …

BACKGROUND & AIMS: Combined pH and impedance monitoring can detect all types of
reflux episodes within the esophageal lumen and the pharynx. We performed a multicenter …

BACKGROUND & AIMS: Intraluminal impedance monitoring has given new dimensions to
the diagnosis of reflux disease. However, there is no defined algorithm for evaluating …

Background Mean nocturnal baseline impedance (MNBI), a novel pH‐impedance metric,
may be a surrogate marker of reflux burden. Aim To assess the predictive value of MNBI on …

Background Positive symptom association probability (SAP) with physiologic esophageal
acid exposure time (AET) on pH‐impedance monitoring defines reflux hypersensitivity (RH) …

Objective Approximately 30% of patients with gastro-oesophageal reflux disease (GORD) do
not achieve adequate symptom control with proton pump inhibitors (PPIs). The aim of this …
