BACKGROUND Proton pump inhibitors and histamine H2 receptor antagonists are two of the most commonly prescribed drug classes for pediatric gastroesophageal reflux disease, but their efficacy is controversial. Many patients are treated with these drugs for atypical manifestations attributed to gastroesophageal reflux, even that causal relation is not proven. OBJECTIVE To evaluate the use of pr...

BACKGROUND Heartburn and regurgitation are considered highly specific symptoms of gastroesophageal reflux. A considerable number of patients with these symptoms do not have endoscopic signs of esophagitis. AIM To study the relationship between gastroesophageal reflux symptoms and 24 h esophageal pH mesurement in patients with normal or near normal endoscopic findings. PATIENTS AND METHODS O...

BACKGROUND Prior studies suggest that obstructive sleep apnea may be associated with gastroesophageal reflux disease, a strong risk factor for Barrett's esophagus. The goals of this pilot case-control study were to determine whether Barrett's esophagus patients have an increased likelihood of obstructive sleep apnea and to determine whether nocturnal gastroesophageal reflux symptoms affect the ...

At the gastroesophageal junction, most vertebrates possess a functional lower esophageal sphincter (LES) which may serve to regulate the passage of liquids and food into the stomach and prevent the reflux of gastric contents into the esophagus. Snakes seemingly lack an LES and consume meals large enough to extend anteriorly from the stomach into the esophagus thereby providing the opportunity f...

BACKGROUND TREATMEN The contribution of eosinophilic esophagitis (EoE) to refractory gastroesophageal reflux disease (GERD) remains unknown. When EoE and GERD overlap, the clinical, endoscopic and histological findings are nonspecific and cannot be used to distinguish between the two disorders. Limited data are available on this topic, and the interaction between EoE and GERD is a matter of deb...

Background Gastroesophageal pathologies are common and multifactorial in patients with type 1 diabetes (T1DM). The evaluation with endoscopy and 24 h pH esophageal monitoring is expensive and not always available in all medical centers, especially in developing countries so more cost-effective algorithms for diagnosis are required. Clinical questionnaires are easy to apply but its utility for g...

AIMS AND BACKGROUND The etiology of laryngeal granulomas is often multifactorial and the benefit of pharmacological therapy remains unclear. Anti-reflux treatment is only effective in granulomas definitely induced by gastroesophageal reflux. Steroid inhalation has shown favorable results but it is unclear whether it shortens the healing process. Surgical excision is associated with high recurre...

Dysmotility of lower esophageal sphincter (LES) is common following gastric surgery. This may result in gastroesophageal reflux which frequently seen following gastric surgery. The aim of this study was to determine the effect of various surgical procedures on esophagogastric motility in dog and human. Esophago-gastric motility was investigated by strain gauge transducers during fasted and fed ...
