Active clinical trials for "Barrett Esophagus"

This study will evaluate, if an intensive individually adaptated training program via online supervision during neoadjuvant therapy will improve lung function and reduce pulmonary complications following esophagectomy for Barrett's cancer.

A pilot study to assess the accuracy and acceptability of a magnet assisted capsule endoscopy in detecting esophageal pathology compared to standard endoscopy.

This is a pilot study to test a newly developed optical coherence tomography (OCT) device to determine 1) whether adequate tissue contact can be attained to acquire high quality images, and 2) to identify if these images can discern whether the imaged tissue is squamous or Barrett's Esophagus (BE) epithelium.

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.

The purpose of this study is to elucidate mechanisms whereby oxidative stress induced by acute reflux esophagitis: 1) activates p38 to regulate proteins that control the G1/S cell cycle checkpoint, and 2) activates HIFs (hypoxia inducible factors) to cause autocrine VEGF (vascular endothelial growth factor) signaling that triggers the EMT (epithelial-mesenchymal-transition) program in Barrett's esophagus.

Gastroesophageal reflux disease(GERD) mainly related to the reflux of stomach content induced by the dysfunction of lower esophageal sphincter. Proton pump inhibitors (PPI) can effectively block gastric acid secretion but the drug reactions and the degree of improvement in symptoms are sometimes unpredictable. The aim of this study is to investigate the association between the clinical efficacy of PPI in patients with GERD and the personal physical status by Ryodoraku and ANSWatch.

This is a feasibility study without a primary study hypothesis or statistical comparison.

The goal of this research is to conduct a pilot clinical study to evaluate the potential use of esophageal Optical Frequency Domain Imaging (OFDI) for assessing the success and degree of injury associated with therapeutic radiofrequency ablation techniques.

To collect efficacy and outcomes data related to the use of trūFreeze® spray cryotherapy for the treatment of unwanted tissue in the pulmonary and gastrointestinal settings.

The purpose of this study is to create a patient registry to collect and analyze post-510K approval information on subjects treated endoscopically with the CryoSpray Ablation™ System.
