Anthropometry in Gastroesophageal Reflux Disease and Esophageal Injury
Gastroesophageal Reflux Disease (GERD)Is waist to hip ratio (WHR), waist circumference (WC), (as markers of visceral adiposity) associated with an increase in acidic and non acidic reflux as well as systemic inflammation involving esophageal mucosa, thereby increasing esophageal injury and predisposing to subsequent development of Barrett's esophagus (BE)?

Assessment of Gastro-esophageal Reflux Using Endo-Flip vs Bravo
HeartburnGastro-esophageal RefluxMonitoring oesophageal pH provides a definitive diagnosis of patients with gastro-oesophageal reflux disease (GORD), especially those in whom the association between reflux and symptoms is uncertain and those under consideration for anti-reflux surgery. Standard ambulatory investigation is normally performed by naso-oesophageal catheter however this is associated with considerable discomfort and in turn altered behaviour which reduces reflux provoking activities. Furthermore results of catheter based ambulatory pH studies are compromised by the high variability of acid exposure in patients with suspected GORD. Prolonging pH measurements by the catheter-free Bravo™ system from 24 to 48 and 96hrs significantly improves the consistency (reliability) and reproducibility of diagnoses based on oesophageal acid exposure, as well as the ability to associate acid reflux to symptom episodes. This improves diagnosis especially in those with intermittent symptoms. However pH monitoring does not provide a direct assessment of the underlying pathophysiology. Incompetence of the oesophago-gastric junction (OGJ) related to disruption of its structure and function is considered to be the most important cause of GORD. A more relevant assessment of the reflux barrier may be its distensibility (i.e. the ease with which the OGJ is opened to allow retrograde passage of gastric contents); however this is not assessed by current clinical investigations. Endo-FLIP (Crospon Medical Devices) is a new tool which assesses OGJ structure and function, and appears to provide relevant information regarding its distensibility and competence. This study applies to using Endo-Flip to record OGJ distensibility and Bravo to record acid exposure and symptom association in patients with reflux symptoms. The variability of pH measurements and symptoms and diagnostic accuracy will be assessed over 96hrs. Endo-FLIP results will then be compared against Bravo. The outcome of post investigation therapy will then be compared with Endo-Flip and Bravo results to assess if baseline testing can predict the outcome of acid suppression therapy. Study Hypothesis There is a positive, continuous association between OGJ distensibility measured by Endo-FLIP on % acid exposure assessed by prolonged Bravo pH monitoring The results of Endo-FLIP and prolonged Bravo predict treatment outcome of a trial of proton pump inhibitor therapy

Gastric Accommodation and Gastroesophageal Reflux
Gastroesophageal Reflux DiseaseGastroesophageal reflux events generally happen during relaxation of lower esophageal sphincter. This relaxation is a reflex that is triggered by gastric stimuli. The investigators hypothesize that abnormal relaxation of the gastric wall after a meal may lead to reflux events. To test this hypothesis, a study was designed to measure the gastric accommodation in patients undergoing esophageal impedance monitoring.

The Efficacy of Neiguan (P6 Point) Acupressure in Patients With Gastroesophageal Reflux Disease...
Gastroesophageal Reflux DiseaseIn recent years, there is an increasing trend in the number of patients with Gastroesophageal reflux disease (GERD). The poor response to medicine was noticed in patients with non-erosive reflux disease. According to the theory of traditional Chinese medicine, acupuncture Neiguan (P6 point) could improve the uncomfortable symptoms of the chest and upper abdomen. Therefore, the aim of this study is to investigate the clinical efficacy of Neiguan (P6 point) acupressure in patients with GERD.

The Primary Symptoms of GERD(Gastroesophageal Reflux Disease) in Chinese Outpatients in Gastroenterology...
Gastroesophageal RefluxConsecutive 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.
