5 Clinical Trials for Various Conditions
In a related study, the investigators have found evidence that patients with Barrett's esophagus have a leak for oral sucrose to leave their upper gastrointestinal tract, enter the blood, and be filtered into urine. The amount of sucrose appearing in an overnight urine sample can be used to indicate the presence of Barrett's esophagus and/or esophagitis in a patient reporting with reflux (GERD) symptoms. The leak is presumably in the Barrett's epithelium itself. This phenomenon will be used to test if a standard 8 week therapy of Nexium in a first-time-presenting GERD patient can reduce the leak as a means of assessing the efficacy of the drug in that patient. The investigators predict that Nexium will reduce leak in esophagitis but not Barrett's patients.
Esophageal stents are commonly used for benign esophageal pathology, especially strictures or esophageal mucosal defects such as leaks, fistulae, or perforations. The major limiting factor to stent placement is the high migration rate of the stent. Investigators are trying to prospectively evaluate the efficacy of endostitch in preventing stent migration in benign esophageal disease in comparison with standard, fully covered self-expanding metal stents (FCSEMS) placement without fixation.
Long term follow-up of patients treated for esophageal fistulas with a newer occlusive self-expanding covered metal stents compared to traditional stents.
The purpose of this study is to test whether after an Ivor Lewis esophagectomy (the removal of a portion of the stomach and esophagus with re-attachment) there is an association between the intraoperative level of oxygen at the site where the esophagus is re-attached to the stomach (measured using the Wipox), and the incidence of a disruption at the site of the attachment after the surgery.
Our institution performs therapeutic ERCP (Endoscopic retrograde cholangiopancreatography ), Endoscopic Ultrasound (EUS) and Interventional Endoscopy in around 1000 patients a year. Procedures such as biliary and/or pancreatic sphincterotomy, stents placement (metallic or plastic) and removal for revision, cysts and pseudocysts drainage are conducted in patients suffering from pancreatico-biliary disorders, gastrointestinal disorders and esophageal disorders. The investigators would like to assess prospectively the efficacy and safety of these routine procedures to permit identification of technical details about the procedures or other factors which might be associated with outcome or results. Assessment of these details would help us with problem identification and recommendations to improve health outcomes and quality of life in these patients.
