Filter by:Capsulomics has developed a prognostic assay for patients with diagnosed Barrett's esophagus (BE). This study will measure how gastroenterologists make surveillance and treatment management decisions when presented with different clinical and prognostic assay information.
Barrett's esophagus (BE) is a premalignant condition of the distal esophagus, predisposing to dysplasia and esophageal adenocarcinoma. Therefore, in BE patients, current guidelines recommend endoscopic surveillance with four-quadrant biopsies every 2 centimeters of the Barrett's length. These biopsies need to be of optimal quality for adequate histopathological assessment. Larger biopsies can facilitate adequate histopathological assessment because (1) more tissue is available, (2) larger biopsies usually result in less superficial biopsies, with all mucosal layers present in the biopsy specimen, and (3) larger biopsies will ease orientation of the specimen. In a pilot study, the investigators found a median increase of nearly 30% in surface area when the biopsies were obtained by BE-expert endoscopists in comparison with non BE-expert endoscopists. A possible explanation for this difference can be biopsy method or technique. BE-expert endoscopists use the single biopsy method and turn-and-suction technique, whereas the double biopsy method and the advance-and-close technique are the more generally used biopsy techniques within non BE-expert endoscopists. The BITE study is therefore designed to identify the preferred biopsy technique and method in BE patients in order to optimise biopsy quality and histopathological assessment.
The goal of this study is to optimize Barrett's Esophagus (BE) screening to reduce the incidence, morbidity, and mortality of Esophageal Adenocarcinoma (EAC).
The Siewert classification of oesophageal cancer is the standard approach in anatomically subdividing cancer of the lower oesohagus.
Gastric and oesophageal (OG) cancer associated with poor long term outcome as overall less than 25% of patients survive for more than 5 years due to late recognition of the disease. Growing evidence suggests an important role for bacteria in OG cancer and gastro esophageal reflux disease (GORD) development. About 1 in 10 people suffer from GORD and this one of the most common conditions leading to gastric and oesophageal cancer. In GORD surgical therapy is the most successful preventing cancer but around 85% of patient experience complications afterwards. Acid suppressing medications are reducing the risk of oesophageal cancer but equally increasing the risk of gastric cancer. They also shorten patients' life expectancy and often fail to provide relief. Analysis of stool samples of patients with GORD demonstrated different gut bacterial compositions to normal and rather resembled the one found in cancer. There is a clear need to improve the outcome of OG cancer. This could be achieved by identifying bacteria responsible for cancer development in gastric tissue, gastric content and saliva and potentially eliminate them hence avoid the development of cancer.
The goal of this research is to follow Barrett's Esophagus patients for 3 years using the tethered capsule endomicroscopy device with distal scanning and a compact imaging system in a multi-site clinical study.
The purpose of this study is to analyze biopsied tissue samples for changes in cells and genes involved in Barrett's Esophagus.
The goal of this research is to determine the natural history of Barrett's esophagus (BE) using tethered capsule endomicroscopy (TCE) in patients undergoing surveillance endoscopy.
The NvisionVLE® Dysplasia Detection Pilot Study is a prospective, non-randomized trial for participants who have a prior biopsy-confirmed diagnosis of BE with dysplasia and are scheduled to have an endoscopic evaluation of your esophagus for BE surveillance by a standard procedure called EGD (esophagogastroduodenoscopy) as well as an imaging procedure called VLE (volumetric laser endomicroscopy).
Assess Cryoablation (CryoBalloon Ablation cryotherapy) for treatment of Dysplastic Barrett's Esophagus, Esophageal Squamous Dysplasia and early Esophageal Cancer. The cryoablation treatment will be offered as an alternative to standard ablation therapies such as Radiofrequency Ablation, Argon Plasma Coagulation and carbon dioxide Cryotherapy).
