Eligibility
Inclusion criteria
Inclusion criteria: • Age > 18 years; • Ability to provide written, informed consent (approved by IRB) and understand the responsibilities of trial participation. • Minimum Barrett’s extent (from Prague criteria) M = 2cm; • Known BE, defined as columnar lined epithelium of the esophagus containing intestinal metaplasia upon biopsy, with or without dysplasia (low-grade or high-grade dysplasia or early adenocarcinoma);
Exclusion criteria
Exclusion criteria: • Presence of an esophageal mass that precludes full distention of the balloon from the NvisionVLE Optical Probe; • Patients with known esophageal strictures, esophageal tears or ulcers, which would prohibit full distention of the balloon from the NvisionVLE Optical Probe; • Contraindications for endomucosal resection (EMR) and/or obtaining biopsies (e.g. due to anticoagulation, coagulation disorders, esophageal varices); • Patients within four weeks of receiving targeted forceps biopsies and/or EMR; • Unable to provide signed informed consent.
