background gastroesophageal reflux disease (gerd) is a common problem seen in pediatrics and adolescents. the bravo tm ph monitoring system is a capsule that detects and quantifies the severity of reflux disease. this test is also valuable for evaluation of patients with extra-gastrointestinal manifestations of gerd such as asthma, chronic cough, hoarseness, aspiration pneumonia, and pre/post f...

introduction: laryngopharyngeal reflux (lpr) is considered an important cause of voice disorder. we aimed to determine the frequency of lpr in patients with voice disorder and the association between koufman reflux symptom index (rsi), reflux finding score (rfs), gastroesophageal reflux disease (gerd), and proximal acid reflux in these patients. materials and methods: we performed a prospective...

BACKGROUND/AIMS The sensitivity of the upper and lower esophageal mucosa to acid is considered to differ. We investigated the relationship between pH changes in different sites of the esophagus and generation of gastroesophageal reflux symptoms during an acid infusion test. METHODS An acid infusion catheter was placed at 5 or 15 cm above the lower esophageal sphincter (LES) in 18 healthy volu...

Our previous finding of a fractal pattern for gastric pH and esophageal pH plus the statistical association of sequential pH values for up to 2 h led to our hypothesis that the fractal pattern encodes information regarding gastric acidity and that depending on the value of gastric acidity, the esophagus can signal the stomach to alter gastric acidity by influencing gastric secretion of acid or ...

T if the study is done to confirm excessive acid exposure or while taking the antisecretory drug regimen if he following guidelines were developed to assist the physician in the appropriate use of esophageal pH symptom-reflux correlation is to be scored). recording in patient care. They emanate from a comprehensive review of the medical literature pertaining to the pH • Esophageal pH recording ...

BACKGROUND/AIMS An association between ineffective esophageal motility and gastroesophageal reflux disease is already known, but there are also some conflicting data. We evaluated the association between ineffective esophageal motility and gastroesophageal reflux disease in patients who underwent ambulatory pH monitoring for the evaluation of reflux symptoms at Gazi University, Gastroenterology...

Newer developing techniques for esophageal functional testing such as wireless pH capsule monitoring and esophageal impedance testing are currently available. However, ambulatory 24 hr esophageal pH monitoring is still widely used and provides quantitative data on esophageal acid exposure and the ability to correlate symptoms with acid exposure events. To properly analyze the result of pH monit...

Received January 5, 2000 Abstract Gastroesophageal reflux (GER) is a common disease found in early childhood. It commonly presents with vomiting and feeding problems. However, it may involve other systems like respiratory system, growth failure. Twenty-four hours esophageal pH monitoring is a useful technique in diagnosis of gastroesophageal reflux. Results of 24 hours esophageal pH monitoring ...

AIM To assess the correlation between esophageal dysmotility, characterized as inefficient esophageal motility (IEM), and the presence of pathological acid reflux due to a structurally defective lower esophageal sphincter (LES), hiatus hernia. (HH), or esophagitis in patients with suspected gastroesophageal reflux disease (GERD). METHODS 311 patients referred for GERD diagnostic procedures in...
