Active clinical trials for "Gastroesophageal Reflux"

The investigators propose a study comparing the morphological and functional aspects of the neosquamous epithelium (NSE) after ablative therapy for dysplastic Barrett's esophagus (BE) to that of native squamous epithelium in normal controls as well as gastroesophageal reflux disease (GERD), non-Barrett's Esophagus (BE) subjects.

Surgical therapy for gastroesophageal reflux disease (GERD) and hiatal hernia (HH) can achieve outcomes that afford the patient lifelong satisfaction. The published results obtained with this surgery may not be considered to be definitive in relation to the length of follow-up or patients' life expectancy. The real recurrence rates and the results of surgery for GERD are difficult to assess due to the lack of serial time points during the follow-up. Further bias may have been introduced into the analysis by a lack of appropriate controls. The results of surgical therapy for type II-IV HH are even more controversial because of the high rate of anatomical relapse and the different methods of follow-up adopted in reported case series. Aim of this study is to clarify the value of surgical therapy for type II-IV HH. The investigators report on patients who were followed up after surgery at various time points over the course of 30 years.

The purpose of this study is to characterize and compare epithelial damage in patients with erosive esophagitis and non-erosive reflux disease.

The purpose of this study is to calculate the prevalence of gastroesophageal reflux disease (GERD) by mean of GERD-Q questionnaire in patients with upper gastrointestinal tract symptoms in Egypt.

The purpose of this study is to evaluate symptoms control and impact on daily life from patients perspective using specific GERD Impact Scale(GIS) questionnaire. The another objective is to obtain local epidemiological data for Bosnia and Herzegovina regarding GERD treatment in primary care.

The purpose of the study is to determine the applicability and utility of Gerd Q in the diagnosis of GERD and in the assessment of treatment response.

To describe GERD digestive expression according to ages: - children (from 0 to 23 months) and (24 months and more)- adults (from 18 to 29 years old), (from 30 to 39 years old), (from 40 to 49 years old), (from 50 to 59 years old), (more than 60 years old)

The purpose of this observational study is to assess the impact of abdominal fat on severity and frequency of GERD symptoms .

PPI test;empirical trial with high-dose proton-pump inhibitors (PPIs) has been shown to be a sensitive tool for diagnosing patients with GERD. However, this diagnostic strategy has not been well established in patients with extraesophageal manifestation of GERD. In this study, we aim to see the relevance of PPI test in diagnosing GERD in patients with extraesophageal symptoms.

The purpose of this study was to gather long-term follow-up data on patients treated with the Plicator in a previous open-label multi-center study. Originally, 64 subjects were treated at seven U.S. sites. A subset of those patients were subsequently reassessed via symptom questionnaires in this long-term (60-month) follow-up analysis. The initial open-label study was completed and officially closed at the completion of 1-year follow-up. This current study was designed to collect long-term follow-up data on previously plicated subjects all of whom were recruited de novo from the original study population. Study endpoints were prospectively defined. The primary study objectives were to assess: reduction in GERD symptoms through analysis of the GERD Health Related Quality of Life (HRQL) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS); reduction in use of GERD medications, and change in overall physical and psychological health as measured by the Short Form Health Survey (SF-36).
