Endoscopic therapy for Barrett's esophagus: a review of its emerging role in optimal diagnosis and endoluminal therapy.

Barrett's esophagus (BE) is a premalignant lesion known to sequentially progress to esophageal adenocarcinoma. Management of BE has changed significantly over the last 5 years with the development of endoscopic resection and ablation, which has replaced esophagectomy as the treatment of choice in BE with high-grade dysplasia. The aim of this review is to discuss the details of these new endotherapies in regards to response and durability and to define the role of these new therapies in the current management of BE.
