Eosinophilic esophagitis (EoE) is a clinicopathologic condition of increasing recognition and prevalence. In 2007, a consensus recommendation provided clinical and histopathologic guidance for the diagnosis and treatment of EoE; however, only a minority of physicians use the 2007 guidelines, which require fulfillment of both histologic and clinical(More)
Our objective was to obtain national data of the estimated prevalence, sociodemographic relationships, and health impact of persons with functional gastrointestinal disorders. We surveyed a stratified probability random sample of U.S householders selected from a data base of a national market firm (National Family Opinion, Inc.). Questions were asked about(More)
BACKGROUND Endoscopic oesophageal changes are diagnostically helpful and identify patients exposed to the risk of disease chronicity. However, there is a serious lack of agreement about how to describe and classify the appearance of reflux oesophagitis AIMS To examine the reliability of criteria that describe the circumferential extent of mucosal breaks(More)
The functional esophageal disorders include globus, rumination syndrome, and symptoms that typify esophageal diseases (chest pain, heartburn, and dysphagia). Factors responsible for symptom production are poorly understood. The criteria for diagnosis rest not only on compatible symptoms but also on exclusion of structural and metabolic disorders that might(More)
OBJECTIVE Limitations of catheter-based esophageal pH monitoring are discomfort, inconvenience, and interference with normal activity. An alternative to conventional pH monitoring is the wireless Medtronic Bravo pH System. The aim of this study was to evaluate the safety, performance, and tolerability of this system. METHODS A total of 44 healthy subjects(More)
OBJECTIVES Esomeprazole, the S isomer of omeprazole, has been shown to have higher healing rates of erosive esophagitis than omeprazole. This study compared esomeprazole with lansoprazole for the healing of erosive esophagitis and resolution of heartburn. METHODS This United States multicenter, randomized, double blind, parallel group trial was performed(More)
BACKGROUND & AIMS The study and management of reflux esophagitis require an endoscopic classification system founded on esophageal lesions that can be reproducibly identified. The aim of this study was to investigate interobserver agreement for the identification of endoscopic lesions typical of reflux esophagitis. METHODS Paired comparisons of observers'(More)
Achalasia is a primary esophageal motor disorder of unknown etiology producing complaints of dysphagia, regurgitation, and chest pain. The current treatments for achalasia involve the reduction of lower esophageal sphincter (LES) pressure resulting in improved esophageal emptying. Calcium channel blockers and nitrates, once used as initial treatment(More)
Radiographic and manometric examinations of the esophagus were correlated in 172 patients with dysphagia. Esophageal manometry was abnormal in 66 (38%), with diagnoses of nonspecific esophageal motor disorder (26), achalasia (19), nutcracker esophagus (12), diffuse esophageal spasm (seven), and scleroderma (two). Compared with manometry, radiographic(More)
Investigations and technical advances have enhanced our understanding and management of gastroesophageal reflux disease. The recognition of the prevalence and importance of patients with endoscopy-negative reflux disease as well as those refractory to proton pump inhibitor therapy have led to an increasing need for objective tests of esophageal reflux.(More)
