Active clinical trials for "Gastroesophageal Reflux"

The purpose of this study is to evaluate the utility of a minimally invasive nasopharyngeal pH probe for the diagnosis of laryngopharyngeal reflux (LPR) in children with airway compromise; to determine whether it is comparable to the gold standard esophageal pH probe in identifying LPR in this population; and to correlate results of pH testing with validated questionnaires. Our hypothesis is that a nasopharyngeal pH probe is equivalent to an esophageal probe in identifying laryngopharyngeal reflux.

The purpose of this study is to determine the efficacy, safety, and tolerability of omeprazole in combination with domperidone in GERD treatment for subsequent efficient pharmacotherapy of GERD. Objectives of the trial To assess the efficacy of omeprazole in combination with domperidone regarding change of incidence and severity of clinical symptoms of GERD during 8 weeks of treatment To compare the efficacy of omeprazole in combination with domperidone regarding change of incidence and severity of clinical symptoms of GERD during 8 weeks of treatment To assess the efficacy of omeprazole in combination with domperidone regarding change of incidence and severity of endoscopic symptoms of GERD during 8 weeks of treatment To compare the efficacy of omeprazole in combination with domperidone regarding change of incidence and severity of endoscopic symptoms of GERD during 8 weeks of treatment To determine the efficiency and advantages of one GERD therapy considering efficacy, safety, and individual variance of patients' reactions

The purpose of this prospective observational research study registry is to examine whether two GERD surgeries (Laparoscopic Nissen Fundoplication (LNF) or Transoral Incisionless Fundoplication (TIF)) have similar outcomes in effectiveness, safety, post-operative side effects and post-procedure costs associated with episodes of care and any ensuing complications.

This study is designed to evaluate the efficacy and tolerability of ilaprazole relative to that of esomeprazole in healing erosive esophagitis and resolving accompanying symptoms of GERD.

Although the symptomatic and epithelial (histologic and endoscopic) response to antireflux therapy are well known and extensively studied, little is known of the genetic events occurring in response to proton pump inhibitor therapy. Preliminary data from our laboratory has shown, for example, that COX-2 expression is not only elevated in patients with gastroesophageal reflux disease but also can be correlated with pathologic esophageal acid exposure on 24 hour pH monitoring. Similar studies have suggested that antireflux surgery may normalize COX-2 gene expression. In contrast studies following ablation of dysplastic Barrett's epithelium have shown persistence of genetic changes associated with altered cellular function, despite the return of the histologic appearance to normal. Several key mediators of inflammation, metaplasia (Barrett's) and neoplasia have now been well characterized and shown to be important factors in the pathogenesis of esophageal injury. It is likely that successful antireflux therapy returns altered expression of these mediators toward normal although this hypothesis remains largely unexplored. The aim of this study is to investigate gene expression of key mediators of the spectrum of esophageal mucosal injury and the response to antireflux therapy. Hypothesis: Antireflux therapy (proton pump inhibitor and surgical fundoplication) normalizes the expression of genes known to be involved in the pathogenesis of inflammation (esophagitis), metaplasia (Barrett esophagus) and neoplasia (adenocarcinoma).

The purpose of this study is to evaluate the efficacy of proton pump inhibitor for the treatment of non-erosive reflux disease (NERD) in Chinese population. Studies from the western population have estimated a worldwide prevalence of gastro-oesophageal reflux disease from 10 to 20 %. Monthly symptoms of heartburn or acid regurgitation were found in 9.3% of subjects according to a population survey in Hong Kong. Most of these patients did not show evidence of erosive change during upper endoscopy. However, patients with NERD suffer from similar impairment of quality of life as patients with erosive oesophagitis and their symptoms are as severe as patients with erosive disease. Data on the use of proton pump inhibitor for the treatment of NERD in Chinese patients are scanty. Thus we want to perform a double-blind randomised placebo-controlled study to evaluate the efficacy of proton pump inhibitor for the treatment of NERD in Chinese population.

Gastroesophageal Reflux Disease (GERD) is a common problem affecting 10-20% of the population in the Western World. Surgical therapy is able to restore the EGJ barrier function against reflux of the gastric content, decreases symptoms and improves the quality of life in GERD patients. However, there remain concerns regarding postoperative adverse events and the durability of the surgical procedure. The ability to perform endoscopic full-thickness plications with Endomina-v2 will be used to assess safety and feasibility of the procedure in reducing GERD in patients suffering with chronic GERD, unsatisfied with PPIs, and/or complaining of persistent GERD symptoms despite PPI use.

Sleeve gastrectomy (SG) has gained popularity as both a staged and a definitive procedure for morbid obesity due to its technical simplicity, low-morbidity and excellent results both for weight loss and control of metabolic syndrome. There are however reports of SG worsening pre-existing GERD or causing new-onset GERD. Because of this, patients with pre-existing GERD have been denied the benefits of SG. In addition, patients that develop post-op GERD cannot undergo traditional anti-reflux surgery since the gastric fundus that is required for fundoplication is removed during the SG. Hence, patients with post-SG GERD not adequately controlled with medication can only opt for the more invasive gastric bypass procedure as their only surgical treatment option. In a recently reported case study, an obese patient with severe GERD successfully treated with EndoStim underwent SG and maintained adequate GERD control with continued use of LES stimulation therapy. However electrical stimulation was not yet tested systematically in patients with prior gastric operation such as sleeve gastrectomy. This study will test the hypothesis that electrical stimulation is effective in control of GERD associated with SG.

The EndoStim LES Stimulation System is an investigational device intended to improve the LES pressure and restore Lower Esophageal Sphincter (LES) function in individuals suffering from Gastroesophageal Reflux Disease (GERD).

The purpose of this study is to demonstrate the superiority of efficacy of DWP14012, once daily (QD), compared to placebo in patients with non-erosive reflux disease at Week 4.
