Endoscopic diagnosis and therapies for Barrett esophagus: a review

Abstract

Barrett's esophagus is an area of great interest in Gastroenterology, with an increasing number of research studies being published in recent years and decades. Due to the fast growing evidence regarding this disease, it has become extremely difficult to keep updated on this subject. The present review article aims to summarize and update what is known regarding diagnosis and therapy in Barrett's esophagus. A critical and detailed review is made and the role of surveillance for this condition, techniques available for diagnosis (standard white light endoscopy, virtual chromoendoscopy, magnification...) and treatment (mucosectomy, ablation...) are presented. New and emerging technologies are described in detail and existing evidence is presented.
