Filter by:This study is being done to find out if Photodynamic Therapy (treatment with a red light and a drug called photofrin) or Radiofrequency ablation works the same for patients who have biomarkers (abnormalities in molecules of cells that may or may not help predict cancer) present in their Barrett's esophagus as for patients who do not have biomarkers.
To assess the effect of ablative therapy (Photodynamic Therapy or Radiofrequency ablation ) on Barrett's Esophagus
This data review will be done to evaluate the use of confocal microscopy imaging in patients who were seen for clinically indicated endoscopic surveillance and biopsies of Barretts Esophagus
This study is being done to determine if a new endoscope will help doctors identify pre-cancer or early cancer lesions in patients who have Barrett's esophagus. This new endoscope allows the doctor to look at the lining of the esophagus in 3 different ways by modifying light.
Existing records will be reviewed to evaluate the predictors of complications including stricture formation, bleeding or perforation associated with endoscopic mucosal resection
This trial is a multi-center clinical and endoscopic outcomes project involving a single large database of patients with Barrett's Esophagus (BE). The initial goal of this project is to define the incidence and prevalence of cancer and high-grade dysplasia (HGD) in patients with BE. Thus, our hypothesis is that systematic collection of data on the natural history of BE and risk factors for progression of BE will provide useful information to develop a decision model for risk stratification and risk reduction strategies in BE.
Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light to create pictures of living tissues and has been successfully used to generate high resolution cross-sectional images of tissue in the human eye and skin. OCT systems are now commercially available for eye and skin use, and several clinical reports on the use of OCT in the gastrointestinal tract have been published as well. The purpose of this study is to develop a high-speed noninvasive OCT probe which can be placed through an endoscope for the early diagnosis of pre-cancerous and cancerous lesions in the gastrointestinal tract. This is a pilot clinical research study that is designed to advance OCT technology, which may in the future be able to replace or augment endoscopic biopsies.
The purpose of this study is to evaluate the demographics, patients symptoms, and findings during endoscopy. Patients presenting for an endoscopy procedure to the KCVA GI endoscopy suite, will be asked to fill out questionnaires pertaining to their symptoms and indications for the procedure. This will be done before their procedure during the interview period preceding endoscopy. The patient's answers to this questionnaire will aid us in determining the prevalence of gastric and esophageal disease in patients presenting with the complaints of dyspepsia, GERD, or extraesophageal symptoms and to also determine whether the presence of any factors (hiatal hernia, NSAID use, age, race, gender, etc.) contribute to the above endoscopic diagnoses.
Primary Aim: In patients with endoscopically suspected BE, compared to standard endoscopy, novel techniques (NBI and AFI) with target biopsies will - Detect more patients with intestinal metaplasia - Detect more areas of high grade dysplasia - Require fewer biopsies and a shorter time for procedure completion Secondary Aim: - Compare the yield of high-grade dysplasia(HGD)using NBI/AFI versus standard endoscopy with biopsy. - Compare the number of biopsies and procedure times for NBI/AFI versus standard endoscopy with biopsy. - Compare the inter-observer variability in classifying different mucosal and vascular patterns observed by NBI/AFI using kappa statistics.
The purpose of this study is to determine or evaluate the risk factors such as smoking, family history etc. that cause esophageal cancer and to determine the genetic changes that lead to esophageal cancer. The investigators hypothesis is that systematic collection of data on the natural history of GERD and BE patients and risk factors for development of BE in patients with chronic GERD and progression of BE to dysplasia and adenocarcinoma will provide useful information to develop a decision model for risk stratification and risk reduction strategies in these patients. As of March 17, 2011, 585 patients have consented at the Kansas City VA Medical Center.
