  • Eradicating Barrett's Esophagus Using Radiofrequency Ablation or a Novel Hybrid Argon Plasma Coagulation Technique

    open to eligible people ages 18-86

    Lay summary: Barrett's Esophagus (BE) involves a change of the esophagus lining (BE epithelium) which in a small proportion of patients could be the starting point for the development of cancer (esophageal adenocarcinoma). Currently, there is evidence that this change is initiated by acid reflux from the stomach which then could progress in a stepwise manner from the healthy epithelium to cellular changes (intestinal metaplasia, low-grade and high-grade dysplasia) and finally to adenocarcinoma. Surgery is considered the standard therapy for this cancer which involves the risk of death and complications with quality of life impairments. New possibilities for treatment have evolved with endoscopic therapies which allow for treatment of early changes of the epithelium (intestinal metaplasia and dysplasia) prior to the occurrence of cancer using either argon plasma coagulation (APC) or radiofrequency ablation (RFA). Both are established methods for eradication of BE by thermal ablation of the BE epithelium using high frequency current (HF). More advanced BE epithelium with early visible cancers are being treated by endoscopic mucosal resection (EMR). After EMR the residual Barrett's epithelium can also be removed by ablation with RFA or APC. Currently radiofrequency ablation (RFA) has been suggested as the standard therapy for BE treatment. Although effective in the eradication of the BE epithelium after RFA treatment the re-appearance of BE epithelium and the occurrence of complications such as strictures causing swallowing impairments for food have also been observed in clinical studies. A recently developed method is Hybrid argon plasma coagulation (ablation) [HybridAPC® (HAPC)] which combines argon plasma coagulation (APC) with a fluid injection function by a water beam. The water beam allows to establish a fluid cushion (normal sterile saline) right beneath the BE-epithelium prior to thermal ablation thereby protecting the esophagus wall from heat during ablation of epithelium with APC. The goal of this randomized controlled study is to investigate if HAPC is non-inferior to RFA in the stricture-free eradication of the dysplastic BE epithelium.
