Tu1152 Safety and Efficacy of Circumferential Radiofrequency Ablation of Barrett's Esophagus Using a Self-Sizing RFA Balloon Catheter: Results of a Pilot Study

Radiofrequency ablation (RFA) for Barrett’s esophagus (BE) generally starts with balloon-based circumferential RFA (c-RFA), followed every 3 months by additional ablation until the entire BE is eradicated. C-RFA requires sizing of the esophageal inner diameter (EID) at multiple levels to select an ablation catheter with an appropriate diameter. A recent study demonstrated that standard c-RFA results in a BE surface regression of 83% at 3-month follow-up, with a median procedure time of 39 min. By incorporating the sizing and ablation balloon into a single device, procedure time may be shortened and this catheter may adjust for differences in EID over the length of the ablation zone.
