In this issue of Endoscopy, several pilot series ap− pear to show the value of radiofrequency ablation (BARRx, HALO) in treating Barrett’s esophagus [1 ±4], mostly with neoplastic changes, with the clear aim of total Barrett’s eradication. Initially, only circumferential ablation devices were used, later supplemented by a focal ablation device. Eradication rates of both Barrett’s esophagus and Barrett’s−associated neoplasia (if flat/invisi− ble) are very high in the articles in this issue, with almost no complications. These reports fol− low an initial large series from the USA, which re− ported the treatment of nondysplastic Barrett’s esophagus, with a complete eradication rate of only 70 % initially [5]; later, with the help of foca
