Wide-field endoscopic submucosal dissection for the treatment of Barrett’s esophagus neoplasia

Background and study aims Implementation of endoscopic submucosal dissection (ESD) for the treatment of Barrett’s esophagus neoplasia (BEN) has been hampered by high rates of positive margins and complications. Dissection with wider margins was proposed to overcome these problems, but was never tested. We aim to compare Wide-Field ESD (WF-ESD) with conventional ESD (C-ESD) for treatment of BEN. Patients and methods This was a cohort study of all...
