Effects of the Learning Curve on Efficacy of Radiofrequency Ablation for Barrett's Esophagus.

ABSTRACT:

Background & aims

Complete eradication of Barrett's esophagus (BE) often requires multiple sessions of radiofrequency ablation (RFA). Little is known about the effects of case volume on the safety and efficacy of RFA or about the presence or contour of learning curves for this procedure.

Methods

We collected data from the US RFA Patient Registry (from 148 institutions) for patients who underwent RFA for BE from July 2007 to July 2011. We analyzed the effects of the number of patients treated by individual endoscopists and individual centers on safety and efficacy outcomes of RFA. Outcomes, including stricture, bleeding, hospitalization, and complete eradication of intestinal metaplasia (CEIM), were assessed using logistic regression. The effects of center and investigator ex
