Development of Evidence-Based Surveillance Intervals After Radiofrequency Ablation of Barrett's Esophagus.

ABSTRACT: BACKGROUND & AIMS:Barrett's esophagus (BE) recurs in 25% or more of patients treated successfully with radiofrequency ablation (RFA), so surveillance endoscopy is recommended after complete eradication of intestinal metaplasia (CEIM). The frequency of surveillance is informed only by expert opinion. We aimed to model the incidence of neoplastic recurrence, validate the model in an independent cohort, and propose evidence-based surveillance intervals. METHODS:We collected data from the United States Radiofrequency Ablation Registry (US RFA, 2004-2013) and the United Kingdom National Halo Registry (UK NHR, 2007-2015) to build and validate models to predict the incidence of neoplasia recurrence after initially successful RFA. We developed 3 categories of risk and modeled intervals to yield 0.
