Endoscopic therapy of Barrett's oesophagus: critical review

Barrett's oesophagus is known as one of the most important risk factor of oesophageal adenocarcinoma. Because of the increasing incidence of these latter, many endoscopic methods such as argon plasma coagulation, photodynamic therapy or endoscopic mucosal resection are now in evaluation in order to eradicate Barrett's oesophagus or to treat dysplasia and early cancers arising from this metaplasia. The aim of this paper is to comment these techniques and discuss their usefulness.
