Arms	Assigned Interventions
Experimental: Radiofrequency ablation Endoscopic radiofrequency ablation of BE	Procedure: Endoscopic radiofrequency ablation HALO device Use of HALO 360° device for the fist procedure and possible use of HALo 90° device for further treatment sessions Treatment zone of 12cm high maximum. Energy delivered 10 J/cm², power 300W
Active Comparator: Surveillance Endoscopic surveillance and PPI treatment	Other: Endoscopic surveillance Upper gastro-intestinal endoscopy every 6 to 12 month under propofol sedation with acetic acid magnification of mucosa and multiple biopsy samples.

Detailed Description:

Background: The occurrence of low grade dysplasia (LGD) in Barrett oesophagus (BE) is known as a pre-cancerous state. Current recommendation in case of LGD is a close endoscopic surveillance every 6 to 12 month and continuous Proton pomp inhibitor (PPI) treatment. Endoscopic radiofrequency ablation (RFA) has been demonstrated as an efficient treatment to eradicate high grade dysplasia (HGD) and most of LGD and BE.

Main aim of this study: To demonstrate that the prevalence of patients with LGD 3 years after a RFA treatment is lower than in a surveillance group.

Patients & Methods: French multicentric randomized controlled trial for patients with BE with confirmed LGD: RFA vs endoscopic surveillance.

120 patients are planned to be included for at least 40 patients randomized in each group.

Primary endpoint: Prevalence of LGD in each group 3 years after randomization

Secondary endpoints:

Prevalence of LGD in each group 1 and 5 years after randomization
Rate of complete eradication of BE at 1, 3 and 5 years after randomization
Incidence of HGD and adenocarcinoma at 3, 5 years after randomization
Rate of complications in RFA group after randomization
Cost - efficacy comparison of the 2 strategies
