Focal cryoballoon versus radiofrequency ablation of dysplastic Barrett's esophagus: impact on treatment response and postprocedural pain

Radiofrequency ablation (RFA) is safe and effective for eradicating Barrett's esophagus (BE), but associated with significant postprocedural pain. Alternatively, balloon-based focal cryoablation (CRYO) has recently been developed, which preserves the extracellular matrix and might therefore be less painful. Although data for CRYO are still limited, uncontrolled studies suggest comparable safety and efficacy to RFA in eradicating limited BE areas. Therefore, secondary endpoints such as pain might become decisive for treatment selection.
