Abstract
Besides esophagectomy and antireflux therapy with intensive endoscopic surveillance, endoscopic ablation therapy is a new treatment modality for Barrett's esophagus (BE) with high-grade dysplasia (HGD). Endoscopic surgical ablation can be performed by either a thermal, chemical, or mechanical method. This article describes the current management of patients with BE and HGD and the various methods of endoscopic ablation, including multipolar electrocoagulation, argon plasma beam coagulation, contact laser photoablation, and photodynamic therapy. It also summarizes the results of 37 patient studies, case reports, and abstracts on experimental endoscopic therapies for BE. The advantages and disadvantages of the various treatment possibilities are considered, and the future direction of the management of BE is discussed.
