Active clinical trials for "Barrett Esophagus"

Barrett's esophagus (BE) is a condition that often occurs in patients who have had GERD for a long time. The researchers are interested in BE because it can sometimes become a cancer in the esophagus. The way that we currently diagnose BE is by performing an upper endoscopy and looking for a change in the color of the esophagus. This color change may represent BE. If the doctor sees this, he/she may take biopsies of this area. Studies have shown that making the diagnosis of BE can be hard to make. One of the reasons why this may be is because doctors may interpret what they see differently during the procedure. In other words, they may see an esophagus that appears normal in color or abnormal in color. The purpose of this study is to compare two doctors' impressions of the appearance of the esophagus during a single endoscopy procedure.

The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach.). The two methods of sampling are: 1) Using forceps that take biopsies (small tissue samples) from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus. By recording the results of all of your biopsies over many years, it may be possible to find out if the brush biopsy, forceps biopsy, or both can predict which patients with heartburn develop Barrett's esophagus, (an abnormality in the esophagus that may lead to cancer), and which patients with Barrett's esophagus develop precancer and cancer. The data from your biopsies will be used to determine the best way to diagnose esophageal disease. You are being asked to participate in the study because you are receiving an upper endoscopy (a procedure where a tube with a light and camera are inserted in your mouth and down your throat) with forceps and brush biopsies of your esophagus as part of your standard clinical care, and you are between the ages of 18 and 80.

The purpose of this study is: To study the components of the gastroesophageal junction high-pressure zone individually and as a group, by pharmacologically eliminating or accentuating the pressure profile generated by the smooth muscle components. To differentiate the gastric sling fibers from the clasp fibers based on the spatial orientation of these muscle groups.

The purpose of this study is to demonstrate the clinical utility of the WavSTAT Optical Biopsy System as an adjunctive tool to improve the endoscopist's clinical sensitivity to identify dysplasia or cancer in the esophagus.

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.

The investigators seek to test the hypothesis that the improved version of high definition white light endoscopes and Narrow Band Imaging (NBI) are more accurate in detecting residual Barrett's Metaplasia and Dysplasia disease after previous resection or ablation treatments than current versions of these endoscopes.

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.

Real-time Diagnosis of Barrett's Esophagus: Comparing Confocal Laser Endomicroscopy with Conventional Histology for the Identification of Specialized Intestinal Metaplasia

The frequency of Barrett's esophagus (BE) has increased in adults in the last decades, but BE is rare in children. Esophageal atresia (EA), the most common congenital anomaly affecting the esophagus, predisposes the patient to severe and prolonged gastroesophageal reflux disease. Because gastroesophageal reflux disease plays a major role in the development of BE by causing repeated mucosal damage, development of BE is a concern even in children and young adults in this specific population. The aim of this study is to assess the prevalence of BE (gastric and/or intestinal metaplasia) in a population of adolescents/young adults who had been treated for EA in early infancy. All eligible patients received upper gastrointestinal endoscopy under general anesthesia with standardized esophageal staged biopsies. Histological suspicion of metaplasia was confirmed centrally.

Patients will be recruited from participating institutions prior to planned routine care EGD with WATS3D brush samples and forceps biopsies. Eligibility will be reviewed and patients who are potentially eligible for the study will be approached regarding the study. If interested, participants will be consented and proceed with routine care EGD. The study coordinator or other research personnel will document information from the routine care endoscopy as part of this research study. Follow-up information collected will include WATS3D cytology and forceps biopsy pathology results from any routine care endoscopy performed during the course of participation in the study, any surgeries received and related to their condition, and any other care received as part of their condition. WATS3D samples will be sent to CDx Diagnostics for analysis.
