[Endoscopic treatment of Barrett esophagus].

The purpose of the treatment of Barrett epithelium in the distal oesophagus is to reduce or even eliminate the increased risk of malignant degeneration in it. This can be achieved by removing the Barrett epithelium, whether or not dysplastic, and to have it replaced by normal squamous epithelium. Drug treatment or surgical antireflux treatment of Barrett epithelium has hardly any effect on the length of the Barrett epithelium or on the occurrence of malignancy. Various forms of endoscopic ablative therapy (laser coagulation, multipolar electrocoagulation, photodynamic therapy and argon plasma coagulation), in combination with antireflux treatment enable removal of the Barrett epithelium with regeneration of squamous epithelium. However, islets of Barrett epithelium may be found beneath the regenerated squamous epithelium and there is also the possibility of malignant potential of pluripotent stem cells left behind in the oesophagus. Future studies will have to afford insight into long-term results, the costs, the side effects of the various methods of treatment and the quality of life of patients during and after treatment of the Barrett oesophagus.
