Filter by:A Study to identify toxicity and optimal photodynamic treatment parameters using the photosensitizer 2-[1-hydroxyethyl]-2-devinylpyropheophorbide-a (HPPH) in high grade dysplasia, carcinoma-in-situ, or early adenocarcinoma in Barrett's esophagus.
Three main adverse reactions, namely photosensitivity (reaction that is similar to sunburn), oesophageal stenosis (narrowing or closure of the food pipe), perforation of the treated area (a tear or puncture of the tissue), have been identified in research studies evaluating photodynamic therapy (PDT) with porfimer sodium. Because of the low incidence of the disease or the variation in the occurrence of these adverse reactions among different indications, it is difficult to determine the occurrence and frequency of these safety issues in routine clinical practice. This post-marketing safety surveillance registry is set-up to evaluate the safety of PDT using porfimer sodium. A registry allows the collection of data to evaluate real-world results in the practice of medicine. The registry will monitor the patient's health and any events, with a main focus on photosensitivity, oesophageal stenosis, and perforation of the treated area. This registry will involve 500 patients, across 20 to 36 hospitals in the US and Europe, scheduled to receive an injection of porfimer sodium with PDT for the treatment of lung cancer, esophageal [food pipe] cancer, or high-grade dysplasia (HGD) (precancerous change in the food pipe tissue) in Barrett's esophagus.
The purpose of this study is to determine if early Barrett's specialized intestinal metaplasia can be detected by measuring early increased blood supply of the esophageal tissue, with 4 Dimensional Elastic Light-Scattering Fingerprinting, (4D-ELF) technology in real time.
The investigators hypothesize that intensive acid suppression with a long acting high potency proton pump inhibitor (PPI) drug dexlansoprazole will lead to a greater decrease in levels of inflammatory mediators (compared to conventional PPIs) in the esophagus, which could potentially lead to decreased recurrence of intestinal metaplasia following endoscopic ablation.
The purpose of this study to assess post ablation, if there are areas of Barrett's mucosa post ablation and to assess the ability of the Fujinon FICE system to detect this, as compared to white light endoscopy. A subgroup will also be compared with laser confocal microscopy
This study focuses on demonstrating the value of probe-based Confocal Laser Endomicroscopy (pCLE) in guiding endoscopic therapeutic procedures in Barrett's Esophagus (BE). It is a randomized controlled outcomes study including patients already treated for Barrett's Esophagus lesion(s) and undergoing high definition white light endoscopy follow up procedure, with or without pCLE (2 arms will be considered in this study). The procedures will be carried out per standards of practice with appropriately trained physicians.
We wish to determine whether biopsies obtained with the technique of fluorescence-aided confocal endomicroscopy will detect more patients with specialized columnar epithelium than random biopsies among patients with Barrett's esophagus who are being monitored with endoscopy.
To compare participation rates in screening for Barrett's Esophagus (BE) using sedated esophagogastroduodenoscopy (EGD), unsedated transnasal endoscopy and capsule endoscopy in a population based cohort. An age and gender stratified random sample of 300 patients from a previously defined (in terms of the presence or absence of symptoms of gastroesophageal reflux using a validated questionnaire) population based cohort from Olmsted County11, 12 using the Rochester Epidemiology Project (REP), who have not undergone endoscopy, will be randomized to undergo screening using capsule endoscopy OR transnasal endoscopy OR conventional sedated endoscopy. The investigators will compare participation rates in the three arms. To identify factors associated with non-participation in population screening for BE. The investigators will compare demographic and clinical factors in participants and non-participants, to help predict non-participation using data from prior surveys (data has been collected on patient demographics, bowel and reflux symptoms, employment, education, somatization behavior, psychological profiles using the validated Gastroesophageal Reflux questionnaire [GERQ] and the Bowel Disease Questionnaire [BDQ]) which have been completed by all targeted subjects. This preliminary will allow us to identify barriers to screening and develop interventions to increase participation in future larger studies.
This is a laboratory-based, exploratory study using tissue obtained from our clinical practice. The purpose of this study is to confirm our ability to characterize miR expression in various tissues (proximal and distal esophagus, stomach and duodenum) obtained from the upper gastrointestinal tract in preparation for the study of MiR in patients with Barrett's esophagus and other inflammatory conditions of the upper gastrointestinal tract.
Study Hypothesis: - PillCam™ ESO-2 will demonstrate equivalent accuracy parameters as compared to blinded esophagogastroduodenoscopy (EGD) in detecting suspected Barrett's esophagus, detecting and grading esophagitis. - PillCam™ ESO will demonstrate all safety parameters as compared to EGD - PillCam™ ESO-2 will demonstrate better patient's satisfaction as compared to EGD
