Catheter-based testing remains the current standard of practice for the diagnosis of
gastroesophageal reflux disease and esophageal motility abnormalities. Ambulatory pH …

Esophageal testing aims to quantify gastroesophageal reflux or characterize esophageal
motility. Reflux monitoring traditionally has been based on the detection of acidic reflux by a …

This review provides an overview of the recent advances made in diagnostic technologies of
esophageal functional disorders. There is discussion of technologies that evaluate …

The understanding of esophageal function and dysfunction in a variety of disease states has
been driven largely by the introduction of a variety of measurement technologies. Included in …

Classical techniques like videofluoroscopy, stationary manometry and ambulatory 24-hour
pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and …

Until recently catheter-based 24-h pH monitoring has been the primary methodology for the
objective diagnosis of gastroesophageal reflux disease. Yet, this system has some …

Endoscopy, barium swallow, high-resolution manometry (HRM), pH measurement (either
catheter based or using Bravo system), and impedance monitoring of the esophagus are …

Esophageal function tests are widely used, not only to obtain insight into esophageal
physiology and pathophysiology in a research setting, but also to diagnose esophageal …

Esophageal symptoms are common, and can arise from mucosal, motor, functional, and
neoplastic processes, among others. Judicious use of diagnostic testing can help define the …

Disorders of gastrointestinal (GI) tract motility and function are prevalent in the general
population and negatively affect quality of life [1]. The principle aim of this editorial is to serve …
