Cotton CC et al. Gastroenterology. 2018 Apr 12. doi: 10.1053/j.gastro.2018.04.011.

Key clinical point: Baseline histologic grade was the most important predictor of recurrence after radiofrequency ablation of Barrett’s esophagus.

Major finding: The proposed surveillance intervals were 1 year, followed by 3 years, followed by more than 5 years for patients with completely eradicated low-grade dysplasia. For cases of high-grade dysplasia or carcinoma in situ, the proposed surveillance intervals were 3 months, 6 months, 1 year, and then annually.

Study details: An analysis of data from the United States Radiofrequency Ablation Registry and the United Kingdom National Halo Registry.

Disclosures: The National Institutes of Health and Barrx/Covidien/Medtronic provided funding. Dr. Cotton reported having no relevant disclosures. Three coinvestigators disclosed ties to Pentax Europe, Medtronic, Beamline Diagnostics, C2 Therapeutics, Boston Scientific, and CDx Medical.
