Feasibility of esophageal endoscopic submucosal dissection after radiofrequency ablation treatment in patients with Barrett's esophagus.

Background and Aims: Radiofrequency ablation (RFA) is a well-established treatment for Barrett's esophagus (BE) in the United States. Similarly, endoscopic submucosal dissection (ESD) has been widely performed for early esophageal carcinoma. However, conducting ESD after RFA can be technically challenging. The aim of this study was to assess the feasibility and safety of ESD in patients with prior RFA.
Methods: This study was a single-center retrospective analysis of patients who underwent esophageal ESD after undergoing prior RFA treatment for BE.
Results: Of 44 esophageal ESD cases, 7 underwent prior RFA. In those 7 cases, the en bloc resection rate was 100%, and the R0 resection rate was 86%. No acute or delayed adverse events or rehospitalizations occurred in any patient.
Conclusions: ESD may be a feasible and safe option for patients with a history of RFA. It could be considered for esophageal neoplasms in patients previously treated with RFA for BE.
