The primary objective is to investigate the adverse events during upper gastrointestinal endoscopy with and without sedation in Chinese population
This phase III trial studies how well domperidone works in treating patients with gastrointestinal disorders. Domperidone may help control chronic gastrointestinal disorders and their symptoms, such as pain, bloating, and nausea and vomiting, by stimulating contraction of the stomach to increase its ability to empty itself of food.
The purpose of the study is to investigate if serological parameters such as "extracellular Serum-Tryptase (ST)" and "eosinophilic cationic protein (ECP)" are useful for the diagnosis and surveillance of the eosinophilic esophagitis (EE).
Acetic acid chromoendoscopy is an established standard technique used to detect dysplasia within the gastrointestinal tract. Acetic acid spray helps to identify neoplasia by highlighting the surface pattern, highlighting the vascular pattern and by a process known as the aceto-whitening reaction, where tissues take acetic acid and turn white for a brief period and then slowly revert back to a normal colour. The neoplastic surface and vascular pattern are all very well described, and have played a big role in the recognition of early cancer. The aceto-whitening reaction is well described but the differential in timing between neoplastic and non-neoplastic areas is not well understood. The investigators aim to establish the differential in the timing of the disappearance of the aceto-whitening reaction between healthy tissue, dysplastic tissue, intramucosal cancer and invasive cancer after acetic acid dye spray in the oesophagus and colon. By understanding this better, the investigators may be able to predict with greater accuracy whether a highlighted abnormal area is cancer or high grade dysplasia, or whether it is low grade dysplasia or inflammation, which has significant prognostic implications for the patient. The investigators hypothesize that the differential in the timing of the disappearance of the aceto-whitening reaction between normal and abnormal tissue could help in the detection of gastrointestinal neoplasia.
Herpes esophagitis presents a clinical diagnostic challenge. The investigators report the first case of herpes esophagitis presenting as vocal fold palsy in an immunocompetent host. The investigators case highlights the importance of performing a detailed laryngoscopic examination in any patient with prolonged husky voice.
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.
The purpose of this study is to identify the prevalence of pathologic eosinophilic esophagitis (EoE) in the cohort of adult patients who present for specialty care in the gastroenterology clinics with complaint of difficulty swallowing (dysphagia). From this, the investigators will make recommendations regarding routine screening for the diagnosis in this cohort. The prevalence of EoE in patients presenting for specialty care in the gastroenterology clinics with the complaint of dysphagia is great enough that the diagnosis should be routinely screened against in this cohort.
Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease of the esophagus affecting children and adults. The most frequent symptoms are swallowing difficulties and thoracic pain. The disease has first been described in the 1980s and is found with rapidly increasing frequency mainly in industrialized countries. The factors that lead to EoE are until now incompletely understood, of importance, the disease is found more frequently in men and patients suffering from allergic diseases (e.g., Asthma). So far there exists no activity index to define the severity of EoE; such an index is urgently needed for future clinical trials to determine the efficacy of current and future therapies. The investigators' 3-year project, carried out in cooperation with international EoE experts, aims at the development of an activity index for adult and pediatric EoE patients that will be used in future clinical trials as well as observational studies.
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.
