Résumé : Barrett's esophagus (BE) is a premalignant lesion that may further develop into dysplasia and lead to adenocarcinoma of the esophagus. Once only performed in referral centers, endoscopic resection (ER) of focal early tumors is now performed in many centers, while referral centers now have programs that include endoscopic mucosal resection, endoscopic submucosal dissection in selected cases and ablation of residual Barrett's, to prevent the development of metachronous lesions after focal ablation. In the nineties some of the thermal ablation techniques used in the setting of BE and early esophageal adenocarcinoma have seen their utility changing or have not yet gained acceptance. These techniques include: photodynamic therapy (PDT), argon plasma coagulation (APC) and cryotherapy (CT). This chapter summarizes the knowledge acquired with these techniques and tries to define the potential residual niches of application as well as possible further progresses which could be made in thermal ablation.
