Filter by: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.
To confirm performance of the Captivator™ EMR device for resection of early neoplasia in Barrett's Esophagus.
Healing of mucosal defects after endoscopic mucosal resection in the oesophagus is prone to result in varying degrees of stenosis, especially if the resected area is large and/or circumferential. A new technique was described where autologous cells from the patients own oral mucosa are harvested and cultures on proprietary membranes (coated, temperature sensitive). These membranes, coined cell sheets, are used to cover the mucosal defects.
This pilot clinical trial studies non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus in screening for Barrett esophagus, a condition where the lining of the esophagus has changed or been replaced with abnormal cells that may lead to cancer. The non-endoscopic inflatable balloon for the esophagus is a capsule balloon that brushes against the walls of the esophagus to collect esophageal samples. Non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus may help doctors find Barrett esophagus sooner, when it may be easier to treat.
The goal of this research is to test the imaging quality of the modified, larger diameter, tethered Spectrally Encoded Confocal Microscopy (SECM) capsule in healthy subjects, subjects with Barrett's Esophagus (BE), and subjects with Gastroesophageal reflux disease (GERD).
This study will assess the Minimally Invasive Esophageal Cytology Collection System in Patients with Barrett's Esophagus or GERD Symptoms.
This study is to assess the diagnostic accuracy and precision of the Probe-based Volumetric Laser Endomicroscopy (pVLE) imaging system in detecting dysplasia in BE in both in vivo and ex vivo imaging of Endoscopic Mucosal Resection (EMR) tissue, as compared to standard histopathology
Confocal endomicroscopy is an emerging technique that allows in vivo imaging of cells and tissue structures of the gastrointestinal mucosa, with a magnification of about 1000 times, guiding optical biopsies in real time. Confocal endomicroscopy represents technique that combines conventional white light image with the confocal microscope probe, thereby allowing examination of the surface epithelium in vivo and histological diagnosis during endoscopy. Among the applications already established for its use, stand out diagnosis of Barrett's esophagus, gastric atrophy and intestinal metaplasia, celiac disease, differentiation of hyperplastic adenomatous polyps of the colon, microscopic colitis and follow-up of patients with inflammatory disease, reducing the need for endoscopic biopsies. The CLE can still detect molecular changes effectively improving the endoscopic diagnosis. This pilot project consists of 07 subprojects which the technology of confocal endomicroscopia will be evaluated and compared with the histological results of biopsy or surgical specimens: 1. confocal endomicroscopy for the diagnosis of high-grade dysplasia and superficial esophageal adenocarcinoma in patients with Barrett's esophagus 2 Diagnosis of superficial esophageal squamous cell carcinoma in patients with head and neck cancer by confocal endomicroscopy 3 Detect the presence of premalignant lesions in the gastric stump in patients with reflux alkaline gastritis after partial gastrectomy 4. detect lesions in the gastric mucosa of patients with familial history of gastric cancer 5 Biliary Strictures: differential diagnosis by confocal endomicroscopia 6 confocal Endomicroscopy of cystic neoplasms of the pancreas 7 Contribution of confocal endomicroscopy for the differential diagnosis of colorectal polyps The project aims to deploy the structure of the Confocal endomicroscopy Endoscopy ICESP, for performing in vivo histological examinations of the digestive tract, biliary tract and pancreas. All research groups involved in the early detection of tumors of the esophagus, stomach, biliary tract, pancreas, colon and rectum may benefit from the implementation of this methodology.
The purpose of this study is to assess the efficacy and performance of the C2 Focal Cryoablation System in patients with BE.
This study is being done to see if treating residual Barrett's Esophagus after previously having undergone Radiofrequency ablation or Endoscopic Mucosal resection can be eliminated with focal cryotherapy.
