INTRADIVERTICULAR BARRETT'S ESOPHAGUS ABLATION WITH CHANNEL RADIOFREQUENCY ENDOSCOPIC CATHETER
A 75-year-old man diagnosed with Barrett's C3M7 esophagus which practically extends entirely inside a distal esophageal diverticulum. Two radiofrequency sessions were performed using a 360º circumferential ablation catheter and a third session using a 90º focal ablation catheter. There was evidence of persistence of focal lesions in the intra diverticular area. We used a catheter inserted through the endoscope channel with a 90º flexible blade, which allowed the access to all the walls of the diverticulum. After a single radiofrequency session with this catheter, complete ablation of the metaplasia within the diverticulum was achieved.
