BACKGROUND & AIMS Radiofrequency ablation (RFA), with or without endoscopic resection effectively eradicates Barrett's esophagus (BE) containing high-grade intraepithelial neoplasia and/or early-stage cancer. We followed patients who received RFA for BE containing high-grade intraepithelial neoplasia and/or early-stage cancer for 5 years to determine the(More)
OBJECTIVE After focal endoscopic resection (ER) of high-grade dysplasia (HGD) or early cancer (EC) in Barrett's oesophagus (BO), eradication of all remaining BO reduces the recurrence risk. The aim of this study was to compare the safety of stepwise radical ER (SRER) versus focal ER followed by radiofrequency ablation (RFA) for complete eradication of BO(More)
OBJECTIVE Focal endoscopic resection (ER) followed by radiofrequency ablation (RFA) safely and effectively eradicates Barrett's oesophagus (BO) containing high-grade dysplasia (HGD) and/or early cancer (EC) in smaller studies with limited follow-up. Herein, we report long-term outcomes of combined ER and RFA for BO (HGD and/or EC) from a single-arm(More)
OBJECTIVES Endoscopic radiofrequency ablation (RFA) eradicates intestinal metaplasia and intraepithelial neoplasia associated with Barrett's esophagus (BE), restoring an endoscopically normal neosquamous epithelium (NSE). We evaluated the post-RFA NSE for genetic abnormalities and buried glandular mucosa. METHODS Eligible patients underwent RFA for BE(More)
BACKGROUND & AIMS Radiofrequency ablation (RFA) is safe and effective for eradicating intestinal metaplasia and neoplasia in patients with Barrett's esophagus. We sought to assess the safety and efficacy of RFA in conjunction with baseline endoscopic resection for high-grade intraepithelial neoplasia (HGIN) and early cancer. METHODS This multicenter,(More)
BACKGROUND Radiofrequency ablation (RFA) is safe and effective for eradicating Barrett's esophagus (BE) and BE-associated early neoplasia. Most RFA studies have limited the baseline length of BE (<10 cm), and therefore little is known about RFA for longer BE. OBJECTIVE To assess the safety and efficacy of RFA with or without prior endoscopic resection(More)
BACKGROUND AND STUDY AIM Endoscopic resection with radiofrequency ablation (RFA) 6 weeks later safely and effectively eradicates Barrett's esophagus with high grade dysplasia (HGD) and early cancer. After widespread endoscopic resection, related scarring may hamper balloon-based circumferential RFA (c-RFA). However c-RFA immediately followed by endoscopic(More)
STUDY AIMS The aim of the current study was to evaluate the efficacy and safety of stepwise circumferential and focal ablation using the HALO system for Barrett's esophagus containing flat, high-grade dysplasia (HGD) or residual dysplasia after endoscopic resection for HGD or intramucosal cancer (IMC). METHODS Visible abnormalities were removed with(More)
BACKGROUND AND STUDY AIMS Stepwise circumferential and focal ablation of nondysplastic Barrett's esophagus has proven safe and effective. This study assessed the efficacy and safety of ablation for Barrett's esophagus with high-grade dysplasia (HGD), and residual Barrett's esophagus with dysplasia after prior endoscopic resection for visible lesions.

BACKGROUND AND AIMS Endoscopic resection is safe and effective to remove early neoplasia (ie,high-grade intra-epithelial neoplasia/early cancer) in Barrett's oesophagus. To prevent metachronous lesions during follow-up, the remaining Barrett's oesophagus can be removed by stepwise radical endoscopic resection (SRER). The aim was to evaluate the combined(More)
