Filter by:To study the role of a novel endoscopic treatment technique (ARMA) in GERD patients who doesn't respond to PPI therapy (Proton Pump Inhibitor).
The purpose of this study was to evaluate the safety and efficacy of endoscopic endoloop pre-test for gastroesophageal reflux before anti-reflux surgery or endoscopic treatment. In the study, the investigators used the novel pre-test to narrow the gastric cardia to control symptoms temporarily to decide whether to undergo irreversible surgery or endoscopic treatment.Thirty patients were enrolled and underwent endoscopic endoloop pre-test treatment. The Primary outcome in this study was measured by the percent reduction in post-procedure GERD symptoms as evidenced by analysis of the GERD-HRQL (Health Related Quality of Life) questionnaire. The secondary outcomes included improvement in esophageal 24-hr pH monitoring, improvement in quality of life questionnaires and safety. Patient follow-up assessments were completed at 7 and 14 days post treatment.
In the past years, the adenocarcinoma of the esophagogastric junction (AEG) has been increasing obviously in China. It may be caused by the reason of increased body weight, alcohol consumption, gastroesophageal reflux disease and premalignant. In western countries, the 5-year rate of advanced AEG was less than 30%, it was the same in China. There was significant difference in epidemiology, pathogenic mechanism, biological characteristics and prognosis between AEG and antrum tumors, so AEG was regarded as a kind of independent disease. Up till now, the scope of lymph node dissected, the selection of operation approach, the resection range and the digestive tract reconstruction for the treatment of AEG were in dispute, especially in the reconstruction of digestive tract after operation. The purpose of this study is to investigate the efficacy and safety of the proximal gastrectomy combined with Giraffe anastomosis for early adenocarcinoma of esophagogastric junction.
The purpose of the study is to investigate the efficacy and dose-effect relationship of X842 capsules at different dosages in the treatment of reflux esophagitis for 4 weeks in comparison with lansoprazole enteric-coated capsules.
Reflux esophagitis is a common complication following distal gastrectomy. According to the investigators preliminary data, an Roux-en--Y gastrointestinal reconstruction in pancreaticoduodenectomy is associated with higher rates of reflux esophagitis. In this study, the investigators will investigate the incidence of reflux esophagitis after above procedure by the 24-h pH monitoring of esophagogastric junction.
By using combination of the expression of COX-2 and NOS and immunologic reaction in the esophagus with manometry of LES and cruel diaphragm and 24 hr esophageal pH monitoring to investigate the mechanisms and to make a new and more clinically applicable clarification of these reflux diseases will be valuable in the clinical management and prevention. We will perform the following works and complete the objectives: 1) comparing the difference of immuno-inflammatory reactions among NERD, reflux esophagitis and Barrett’s esophagus; 2) the different expression of PGs & COX-2 in functional heartburn, hiatus hernia, NERD, reflux disease and Barrett’s esophagus; determining the subtype of EP receptor (EP1~4); 3) determining and comparing the expression of NOS in the esophagus; 4) investigating the role of ROS in the esophagus; 5) in correlating cytokine, COX-2 and NOS with LESP, TLESR, diaphragm EMG and 24-hour esophageal pH ; 6) the difference of expression of cytokine, atrophic gastritis and Hp in gastric mucosa, in correlating with intragastric acid status, among functional heartburn, hiatus hernia, NERD, erosive esophagitis and Barrett’s esophagus; to determine whether should eradicate Hp in reflux esophageal disease; 7) the effects of lipid peroxidation related immunologic reaction, with relation to COX-2 and NOS, in the inflammatory activity and esophageal carcinogenesis of esophagus; 8) the effects of cytokines, COX-2 and NOS on the apoptosis in these reflux esophageal diseases; 9) integrating immuno-inflamatory reaction, COX-2, NOS with manometry of LES and diaphragm, and 24-hour pH monitoring and intragastric pH to newly clarify GERD into evidence based categories.
We hypothesize that gastric dysrhythmias may predispose the occurrence of gastroesophageal reflux.
