Ten patients with endoscopically and histologically proven CIP and symptoms of globus or sore throat were included in the study. An ablation protocol of 3 ablations at 12 J/cm2, without removal of coagulated tissue between ablations, was used. A maximum of 2 RFA sessions, 3 months apart, was allowed. A visual analog score was completed at baseline, 6 weeks (on proton pump inhibitor), 3 months (off proton pump inhibitor), and 12 months after treatment.
Mean patient age was 56 years (±3 years, standard error of the mean), 60% were men, and 80% were white. Barrett’s esophagus was present in 50%. The mean number of CIPs was 2 (range, 1-4) with a median surface area of 2 cm2 (range, .5-14). After a median of 2 treatments, 80% achieved complete endoscopic and histologic resolution, with a mean follow-up of 14 months (range, 12-17). Globus, sore throat, and cough significantly improved from baseline (P < .05). No strictures or buried glands were identified.
This prospective pilot study demonstrates that RFA using a through-the-scope device is safe and effective for treating patients with symptomatic CIP. One-year follow-up data suggest the effect is durable.
