EMR Versus ESD for Barrett's Neoplasia

Rationale: The optimal technique for removal of visible dysplastic lesions in Barrett's esophagus remains controversial. Endoscopic mucosal resection (EMR) is safe, effective, easy to apply, and has been the most widely used technique since 2008. Endoscopic submucosal dissection (ESD) is a more controlled dissection method with potential improved efficacy, but at the cost of higher technical complexity. Objective: The investigators aim to compare EMR and ESD for removal of visible lesions in Barrett's esophagus. Study design: Randomized clinical trial Study population: Patients with Barrett's esophagus and a visible lesion with dysplasia and/or early cancer. Suspicion for submucosal invasion is an exclusion criterion. Intervention: Patients are randomized to receive either EMR or ESD, with follow-up and no ablation during 12 months after the resection. Main study endpoint: Primary endpoint is the proportion of patients with no evidence of residual or local recurrent neoplasia during 12 months follow-up after baseline.

Inclusion Criteria: * Patients age: ≥ 18 years * Willingness to undergo both EMR or ESD * Ability to provide written, informed consent (approved by IRB) and understand the responsibilities of trial participation * BE with at least one visible lesion ("target lesion") with absence of signs of submucosal invasion on endoscopy, after evaluation by the adjudication committee * Multiple lesions are allowed as long as the lesions are considered eligible for endoscopic treatment. Only the target lesion is evaluated for the study * Prior endoscopic resection is allowed Exclusion Criteria: * Patients with visible lesions with suspicion of submucosal invasion based on assessment of the adjudication committee * Patients with HGD in at least one random biopsy, before inclusion (i.e. during endoscopy in the referring center \2.0, thrombocytopenia with platelet counts \< 50,000 * Esophageal varix or varices * Subject has a known history of unresolved drug or alcohol dependency that would limit ability to comprehend or follow instructions related to informed consent, post-treatment instructions, or follow-up guidelines * Life expectancy \
