OBJECTIVES Bronchiolitis obliterans syndrome is a significant postallogeneic hematopoietic stem cell transplant problem. Recent data in lung transplant patients suggest an association with gastroesophageal reflux disease and bronchiolitis obliterans syndrome. We studied posthematopoietic stem cell transplant patients with bronchiolitis obliterans syndrome for gastroesophageal reflux disease and...

BACKGROUND/AIMS Glycogenic acanthosis is described as benign thickening of the esophageal squamous epithelium of unknown etiology. Although its etiology is unknown, it has been reported that glycogenic acanthosis may be related to gastroesophageal reflux and hiatal hernia. The aim of the present study was to review the patients who were diagnosed with glycogenic acanthosis on upper gastrointest...

BACKGROUND/AIMS Detailed characterization of the ultrastructural morphology of intercellular space in gastroesophageal reflux disease has not been fully studied. We aimed to investigate whether subtle alteration in intercellular space structure and tight junction proteins might differ among patients with gastroesophageal reflux disease. METHODS Esophageal biopsies at 5 cm above the gastroesop...

OBJECTIVES Severe asthma is found in approximately 10% of patients with asthma. Some factors associated with worse asthma control include rhinitis, gastroesophageal reflux disease, vocal cord dysfunction (VCD), nasal polyposis and bronchiectasis. Therefore, we evaluated the prevalence of these illnesses in patients with severe asthma. METHODS We conducted a retrospective analysis of data obta...

Placement of self-expanding, coveredmetal stents is the first choice of management in the palliative therapy of unresectable esophageal cancer. These stents have a much higher rate of stent migration (27% compared with 8.7% of uncovered stents), and migration occurs more often at the gastroesophageal junction as the distal part of the stent is not fixed to the esophagealwall andprojects freely ...

BACKGROUND The role of gastropharyngeal reflux in patients with globus pharyngeus and hoarseness remains unclear. OBJECTIVE To evaluate patients with complaints of globus, hoarseness, or globus and hoarseness combined for the presence of gastropharyngeal and gastroesophageal reflux. DESIGN Prospective clinical cohort study of 3 groups of patients undergoing ambulatory 24-hour double-probe p...

BACKGROUND/AIMS Obesity is regarded as an important contributor to the increasing occurrence of gastroesophageal reflux disease. The aims of this study were to determine whether obesity is associated with gastroesophageal reflux in patients with gastroesophageal reflux disease and to identify the factors affecting increased acid exposure in obese patients. METHODS We retrospectively analyzed ...

The aim of this study was to combine the anatomy and physiology of the human gastroesophageal junction (the junction between the esophagus and the stomach) into a unified computer model. A three-dimensional (3D) computer model of the gastroesophageal junction was created using cross-sectional images from a human cadaver. The governing equations of finite deformation elasticity were incorporated...
