Active clinical trials for "Gastroesophageal Reflux"

Per Oral Endoscopic Myotomy has been established as a safe and effective treatment of Achalasia type I and II; however, it is limited by post-procedure gastroesophageal reflux. Transoral Incisionless Fundoplication (TIF) has been introduced as the endoscopic gold standard for anti-reflux procedure. Recently, combined POEM-TIF has been performed successfully as a standard of care treatment for patients with severe GER after POEM. We aim to study the safety and feasibility of performing POEM-TIF (POEM and TIF in the same endoscopic session). This study will also put the groundwork for a randomized clinical trial to further study the clinical outcome of the POEM-TIF procedure.

When treating persistent heartburn from gastroesophageal reflux disease (GERD) that does not respond to conventional treatment (a class of medications called proton pump inhibitors), it is important to be able to distinguish between erosive GERD and non-erosive GERD (called NERD). Currently the best method the investigators have to make this distinction is esophageal 24-hour pH and impedance testing. The test involves inserting a catheter into the esophagus through the nose and having the catheter maintained in this position for 24 hours This test is invasive, can be uncomfortable, and it is expensive and time consuming. The investigators are hoping that image enhanced technology will identify characteristics that are found more commonly in patients with non-erosive GERD compared to controls and therefore provide evidence that may allow us to replace pH and impedance testing with the image enhanced endoscopy as the best way to diagnose NERD. Participants will be either patients undergoing an upper endoscopy as part of their standard clinical evaluation for heartburn that does not respond to PPIs or patients undergoing standard clinical evaluation endoscopy for other reasons.

Consecutive patients aged 18-65 years who go to the gastroenterology clinic presented with upper gastrointestinal discomfort would be included. All patients underwent upper endoscopy or an ambulatory 24-h pH(Potential Of Hydrogen) monitoring.Pathologic esophageal acid reflux was defined as the percentage total time for which a pH value < 4 was >4.2 % in the distal esophagus. Then, patients were treated with esomeprazole 20 mg twice daily for 28 days. The symptom scores were measured by the frequency score multiplied by the severity scores of the predominant symptom before and at the end of the treatment, and the " PPI test " was defined as positive if the overall scores of the predominant dyspeptic symptom in the fourth week decreased by >50 % compared with those of the baseline. GERD is defined by either 24-hour impedance-pH monitoring or positive PPI(proton pump inhibitor) test or positive result from endoscopy. The percentage of each symptom of GERD in the symptom questionnaire in Chinese outpatients in Gastroenterology department will be calculated. The symptom of the highest percentage will be the primary symptom.

The frequency of Barrett's esophagus (BE) has increased in adults in the last decades, but BE is rare in children. Esophageal atresia (EA), the most common congenital anomaly affecting the esophagus, predisposes the patient to severe and prolonged gastroesophageal reflux disease. Because gastroesophageal reflux disease plays a major role in the development of BE by causing repeated mucosal damage, development of BE is a concern even in children and young adults in this specific population. The aim of this study is to assess the prevalence of BE (gastric and/or intestinal metaplasia) in a population of adolescents/young adults who had been treated for EA in early infancy. All eligible patients received upper gastrointestinal endoscopy under general anesthesia with standardized esophageal staged biopsies. Histological suspicion of metaplasia was confirmed centrally.

Chronic esophageal disorders affect approximately one third part of global population, with a deleterious impact in the quality of life of patients. Measured of health related quality of life in chronic esophageal conditions such as gastroesophageal reflux disease and achalasia are widely used to measure this important patient-reported outcome. The Northwestern Esophageal Quality of Life (NEQOL) is a hybrid measure of esophageal illness, allowing for broad use across esophageal diseases while maintain sensitivity to nuances of a specific condition. The NEQOL is a reliable and valid hybrid measure of disease specific health related quality of life across several chronic esophageal conditions. The Ecuadorian Institute of Digestive Diseases aims to translate and validate this survey into Spanish for its use in a Hispanic population. This cross-sectional study aims to translate, apply and validate the NEQOL in the patients attending in the esophageal division of the institute.

The purpose of this study is to find out some potential biomarkers for the Eosinophilic Esophagitis (EoE) in pediatric patients through the prospective clinical characterization and assessment of samples collected during the diagnostic process

This study evaluates the treatment of newly diagnosed gastro-esophageal reflux disease in a Danish national cohort, comparing medical and surgical treatment.

MGB is considered to be the best alternative to Roux-en-Y gastric bypass (RYGB) due to the shorter operation time and fewer possible complications. The purpose of this study was to determine biliary reflux in patients undergoing MGB/OAGB with a hand-sewn gastroenteroanastomosis, and MGB/OAGB with a stapler gastroenteroanastomosis.

Esophageal dysmotility due to immaturity could promote impaired bolus transit during esophageal swallow events,thus influencing gastroesophageal reflux (GER) clearance. Aim of this study was to describe esophageal bolus transit characteristics during swallow and to evaluate the relationship between esophageal swallow (ES) and GER in newborns with gastroesophageal reflux disease symptoms using multichannel intraluminal impedance. The simultaneous analysis of swallow and GER events in newborns undergone MII/pH monitoring could provide useful information to better understand the physiopathology of gastroesophageal reflux disease (GERD) and could help clinicians to identify newborns with prolonged esophageal clearance time, making the recommendations for further tests and the therapeutic approach more accurate

The investigators would like to determine if there are patients with PPI responsive Eosinophilic Esophagitis Infiltration that have significant loss of esophageal distensibility suggestive of esophageal fibrosis typical of classic Eosniophilic Esophagitis. If this group of patients exists, the investigators would like to determine if they have the typical endoscopic features of EoE rather than those of GERD.
