BACKGROUND Incidence rates of both obesity and gastro-oesophageal reflux disease (GERD) are increasing, particularly in the Western world. It has been suggested that GERD symptoms may be improved by weight reduction. AIM To review the literature on the effect of various weight reducing modalities on manifestations of GERD in obese patients. METHODS A(More)
OBJECTIVES The roles of intragastric pressure (IGP), intraesophageal pressure (IEP), gastroesophageal pressure gradient (GEPG), and body mass index (BMI) in the pathophysiology of gastroesophageal reflux disease (GERD) and hiatal hernia (HH) are only partly understood. METHODS In total, 149 GERD patients underwent stationary esophageal manometry, 24-h(More)
BACKGROUND The Rome III criteria classify patients with a positive relationship between symptoms and reflux episodes but a physiological oesophageal acid exposure time as having gastro-oesophageal reflux disease (GORD) with an acid hypersensitive oesophagus. The long-term outcome of antireflux surgery in these patients was investigated. METHODS Outcomes(More)
OBJECTIVES We set out to investigate the impact of the preoperative reflux pattern on long-term outcome after Nissen fundoplication. Recent studies disagree on whether patients with pathological upright reflux should be discouraged from undergoing surgery. METHODS A total of 338 patients underwent Nissen fundoplication. Of these, 234 of 289 patients had(More)
OBJECTIVE Previous studies have reported an overlap between gastroesophageal reflux symptoms, functional dyspepsia (FD) and irritable bowel syndrome (IBS). The aim of this study was to investigate the prevalence of FD and IBS in gastroesophageal reflux disease (GERD) and the effect on health-related quality of life (HRQoL). MATERIAL AND METHODS FD and IBS(More)
OBJECTIVES Visceral hypersensitivity is involved in the etiology of reflux symptoms. Familial clustering and twin studies demonstrated a genetic predisposition to gastroesophageal reflux disease (GERD). G-protein-coupled receptors (GPCRs) mediate the response to acid, neurotransmitters and humoral factors modulating esophageal sensory function. Thus,(More)
Previous studies addressing the effects of acid reflux and PPI therapy on gene expression in oesophageal epithelium concentrated on inflamed tissue. We aimed to determine changes in gene expression in non-inflamed oesophageal epithelium of GERD patients. Therefore, we included 20 GERD patients with pathological total 24-hr acid exposure of 6-12% and SAP >(More)
Studies comparing pH-metrically well-characterized gastro-oesophageal reflux disease (GORD) patients with physiological reflux to GORD patients with pathological reflux, with regard to clinical and epidemiological data, are lacking. We included 273 GORD patients with pathological 24-h pH-monitoring (pH+), defined as pH<4 > or = 6% of time. A symptom index(More)
SUMMARY The aim of this study was to validate a translated version of an achalasia-specific quality-of-life questionnaire (achalasia-DSQoL) by examining its psychometric properties in a Dutch cohort of achalasia patients. The achalasia-DSQoL was administered to 171 treated achalasia patients together with a clinical symptom score and the RAND-36. Validation(More)
BACKGROUND Duodenal signaling affects esophageal motility and perception, both pathophysiological factors in gastroesophageal reflux disease (GERD). Duodenal gene expression abnormalities, contributing to altered esophageal sensorimotor function, have not been reported to date. AIM To identify differentially expressed genes in GERD patients' duodenum. (More)
