Filter by:The purpose of the study is to evaluate the superiority of anterior crural repair during sleeve gastrectomy over no repair in decreasing the incidence of gastroesophageal reflux disease.
Gastro-esophageal reflux disease (GERD), the most common cause of erosive esophagitis (EE), remains highly prevalent worldwide. GERD poses substantial burden on both patients and society. EE treatment patterns and unmet needs have been well-studied overseas, but evidence gaps still exist in China. To fill these evidence gaps, real-world evidence for GERD and EE are needed. To understand GERD market we will analysis :Patient profile,GERD patient journey within hospital (first present, get diagnosed, receive initial and maintenance treatment),medication cost,department differentiation. To investigate current treatment patterns of GERD / EE in China we will analysis: Current agents used and treatment duration in clinical practice treatment patterns by different reimbursement status treatment pattern by EE/NERD. To get healing rate of EE we will analysis: Real-world efficacy of the current standard treatment (i.e. PPIs) for patient with two test results of gastroscopy. The data required for this project are accessible in hospital electronic system; no specific data collection tools or methods are required for this project design. Only algorithms for retrieving and extracting eligible patients' records are required and will be developed by HLT based on the eligibility criteria defined in this protocol.
Gastro-esophageal reflux disease (GERD) is defined as the reflux of gastric content into the esophagus that causes troublesome symptoms or complications. Nine to 30% of the population suffers from GERD-suggestive symptoms (heartburn, regurgitation, chest pain, chronic couch, sore throat). In the absence of warning signs, proton pump inhibitors (PPI) are prescribed as first-line treatment. However, 20 to 60% of patients are unsatisfied because of persistent symptoms when taking PPI. Causes of persistent symptoms are: erroneous diagnosis of GERD (up to 50% of PPI non-responders), rumination syndrome, excessive weakly acid reflux on PPI due to defective esophago-gastric junction or an excessive number of transient lower esophageal sphincter relaxations (main mechanism of GERD), poor acid secretion inhibition on PPI, and non-compliance to therapy. Complementary examinations are indicated to explain persistent GERD symptoms. Upper gastro-intestinal endoscopy is performed first to rule out an esophageal tumor and to identify erosive esophagitis, a specific sign of GERD. However, it is normal in up to 70% of symptomatic GERD patients. Direct detection of reflux episodes is then requested to confirm GERD. The gold standard for reflux detection is the ambulatory measurement of esophageal pH for 24 to 96 hours using a catheter (catheter-based pH-monitoring) or a capsule clipped into the esophagus (wireless pH-monitoring). Reflux episodes are defined as an esophageal pH < 4. Another method of reflux detection is based on liquid and gas detection in the esophagus using pH-impedance monitoring. Recently the combination of impedance and esophageal pressure monitoring, called esophageal high resolution impedance manometry (HRIM) was introduced to simultaneously identify reflux episodes and their mechanisms. It has several advantages over esophageal pH measurement: shorter recording duration (1 or 2 hours post prandial) and identification of reflux mechanisms that might guide the choice of the best therapeutic option. Hypothesis: The 1-hour post prandial esophageal HRIM might be useful to diagnose GERD.
The PASS test is only available and valid tool for the evaluation of persistent acid-related symptoms in patients receiving PPI therapy. There is lack of a validated Chines version of PASS questionnaire for the GERD patients with partial response to proton pump inhibitor (PPI). The English version of PASS test will be translated to traditional Chinese by using forward-backward procedure, and the Chinese version of PASS test will be validated its psychometric properties in Hong Kong population. Eligible subjects will be invited to administer questionnaires to evaluate the psychometric properties of the Chinese version of PASS test.
