Radiofrequency ablation and endoscopic mucosal resection for dysplastic barrett's esophagus and early esophageal adenocarcinoma: outcomes of the UK National Halo RFA Registry.

Background & Aims: Patients with Barrett's esophagus (BE) and high-grade dysplasia (HGD) or early neoplasia increasingly receive endoscopic mucosal resection and radiofrequency ablation (RFA) therapy. We analyzed data from a UK registry that follows the outcomes of patients with BE who have undergone RFA for neoplasia.

Methods: We collected data on 335 patients with BE and neoplasia (72% with HGD, 24% with intramucosal cancer, 4% with low-grade dysplasia [mean age, 69 years; 81% male]), treated at 19 centers in the United Kingdom from July 2008 through August 2012.
