Active clinical trials for "Gastroesophageal Reflux"

Gastroesophageal reflux disease (GERD) is currently defined as "a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications". Doctors often diagnose and treat GERD based on symptoms of heartburn and regurgitation. In recent years, the prevalence of partial or non-response to Proton Pump Inhibitors (PPI) has increased resulting in diagnostic testing with esophagogastroduodenoscopy (EGD) or ambulatory pH monitoring. Most patients do not have endoscopic evidence for reflux. Thus, in this group pH monitoring has emerged as an important physiologic test to determine the degree of esophageal acid exposure and to assess the association between patients' persistent symptoms and acid reflux events. The aims of this study are to assess the sensitivity and specificity of symptom associated indices and determine the best parameter for predicting GERD from a list of conventional pH measurement findings.

Background The existence, diagnosis and treatment of short esophagus is one of the controversies of the past which has recently re-emerged The missed diagnosis of short esophagus and the consequent inadequacy of treatment is one of the major causes of failure of antireflux surgery. The daily clinical practice of surgeons dedicated to therapy of esophageal diseases could take advantage of the definition of frequency, preoperative predictors, intraoperative management and post operative outcomes of cases of foreshortened esophagus, in order to offer the patient affected by GERD the elements necessary for a conscious choice of therapy and to plan the best performance of the surgical procedure. Aims of the Study To define the percentage of cases among the total of antireflux procedures performed, in which, after standard isolation of the ge junction and eventual dissection of the mediastinal esophagus at least two centimetres of esophagus can not be replaced without any applied tension below the apex of the diaphragmatic hiatus. To define the percentage of surgical procedures aimed to treat electively a condition of non reducible G-E junction and foreshortened esophagus, among a multicentric formed case series of patients submitted to antireflux surgery. To define the preoperative clinical and instrumental predictors for a surgical procedure aimed to treat foreshortened esophagus. To record the intra-operative, postoperative, 6 month and 12 month outcome of procedures adopted for the surgical treatment of GERD. Materials and Methods The study will comprise patients in which surgical therapy for GERD is indicated according to the international guidelines and the Centres policy . Patients will be submitted to the antireflux procedure chosen by the surgeon according to the internationally recognized scientific surgical principles and the personal judgement. The preoperative study and the postoperative follow up adopted in the present study are accepted by the Centres as they correspond to the international guidelines and the Centres' current practice criteria for the surgical treatment of GERD.

Recent data has suggested that GER (gastric reflux) may worsen after lung transplantation and potentially increase the risk of chronic rejection (CR) after lung transplantation. The purpose of this study is to look at how often GER occurs in the lung transplant population and examine how GER may change the immune system and cause CR. In this way, we would be able to better identify patients that may benefit from anti-reflux procedures.

The primary objective of the study is to describe the change in GerdQ sum scores, after a 4-week period of systematic treatment with PPIs(using GerdQ questionnaire). The secondary objectives are: to measure the response at the current treatment after a 4-week period of systematic treatment and to identify the percentage of patients which require alterations of their treatment (GerdQ questionnaire)

The purpose of this study is to examine patient's perspective of symptom control and impact of gastroesophageal reflux disease (GERD) on daily life.

The goal of this project is to determine the long-term health outcome of children diagnosed with gastroesophageal reflux (GER). We are inviting subjects that were previously followed in the Pediatric GI programs at Massachusetts General and Children's Hospital, Boston. We have compiled a database of more than 200 subjects that completed diagnostic testing for GER in the 1970's and 1980's. Subjects are being contacted initially by mail using a previously approved recruitment letter. Subjects that fail to respond to this recruitment letter are called by phone. In each case, contact information has been abstracted from the Children's Hospital database. Subjects are then given the opportunity to complete a questionnaire either by phone or in hard copy. Subjects receive no compensation for their participation in this study. Subjects will be compared to controls. Controls will complete the same questionnaire as the subjects. Inclusion of potential controls will be determined by a lack of medical history of gastroenterological diseases before the age of 21 and whether the potential control was born within a year of a subject in the study. Controls will receive $25 to participate in the study.

This a non-interventional multi-centre study to evaluate the symptom load and management strategies in PPI-treated GERD patients with persistent GERD symptoms..

Gastric reflux into the oesophagus may further lung damage in respiratory disease. The proportion of adults with chronic lung disease and gastric reflux is unknown. Adults with this disease regularly complete physiotherapy but the contribution of physiotherapy to reflux is unknown. This study will measure gastric reflux in adults with chronic lung disease, using 24 hour acid monitoring. It is anticipated that approximately 50% of adults with chronic lung disease will have gastric reflux. After monitoring, the number of gastric reflux episodes will be calculated. The results will identify the extent of the gastric reflux problem in these patients and will enable appropriate medical treatment and modifications to physiotherapy, which may improve lung function and quality of life.

The purpose of this study is to define the endoscopic findings of minimal change that is significant to clinical significant reflux esophagitis. Through this, the investigators want to estimate the applicability of minimal change findings of reflux esophagitis to the clinic.

The purpose of this study is to evaluate the impact of gastroesophageal reflux disease (GERD) treatment in primary care setting on symptom control and daily life in symptomatic GERD patients, using both GERD questionnaire and clinical symptoms assessment
