Objective: To evaluate the relationships between symptoms and 24-h oesophageal pressure
and pH data. Methods: Data from 193 consecutive patients (98 men, 95 women) referred to …

Long-term esophageal pH-metry has become the preferred test to quantify acid
gastroesophageal reflux, but its accuracy in separating physiologic from pathological reflux …

Because of the excellent pioneering work by Doctors Tom DeMeester and Larry Johnson in
the 1970s, prolonged pH monitoring became recognized for its great potential to provide …

Depending on how one defines gastroesophageal reflux disease, there are three
approaches that can be used in evaluating therapy. The symptomatic approach defines the …

Twenty-four-hour recording of pH is now generally accepted as the most accurate method of
assessing gastro-oesophageal reflux [1]. Conventionally the pH electrode is positioned 5 cm …

Conventional oesophageal manometric studies are open to criticism in that they take place
on fasted immobile subjects in the artificial setting of a motility laboratory. A new 24‐h pH …

Whereas previous studies have unequivocally shown that esophageal motility is abnormal
in patients with severe reflux esophagitis, the results of motility testing in patients with low …

Much has been learned about the pathophysiology of gastroesophageal reflux and
esophagitis since 24 h intraesophageal pH monitoring allowed objective documentation of …

In this study 24 hour oesophageal pH and pressure monitoring was used to assess
oesophageal motility and acid clearance in 27 patients with refluxoesophagitis (Savary …

METHODS Patients Twenty-seven consecutive patients with increased esophageal acid
exposure on 24-h esophageal pH monitoring, were studied. None of the patients had endo …
