BACKGROUND AND AIMS: Endoscopic resection (ER) is safe and effective for Barrett's esophagus (BE) containing high-grade dysplasia (HGD) or mucosal adenocarcinoma (T1A); risk of metachronous neoplasia is reduced by ablation of residual BE using radiofrequency ablation (RFA) or argon plasma coagulation (APC). These have not been directly compared. We aimed to recruit up to 100 patients with BE and HGD or T1A confirmed by ER over 1 year in 6 centres in a randomized pilot study. METHODS: Randomization was 1:1 to RFA or APC (4 treatments allowed at 2 month intervals); recruitment, retention, dysplasia clearance, clearance of benign BE, adverse events, healthcare costs, and quality of life (QoL) using EQ-5D, EORTC QLQ-C30, OES18 were assessed up to the end of the trial at 12 months. RESULTS: Of 171 patients screened, 76 were randomized to RFA (n=36) or APC (n=40); mean age was 69.7, 82% male. BE was <5 cm (n=27), 5 to 10 cm (n=45), and >10 cm (n=4). Sixty-five patients completed the trial. At 12 months, dysplasia clearance was RFA 79.4% and APC 83.8% (OR, 0.7; 95% CI, 0.2-2.6); BE clearance was RFA 55.8%, and APC 48.3% (OR, 1.4; 95% CI, 0.5-3.6). A total of 6.1% (RFA) and 13.3% (APC) had buried BE glands. Adverse events (including stricture rate after starting RFA 3/36 [8.3%] and APC 3/37 [8.1%]) and QoL scores were similar, but RFA cost £21,147 more per case than APC. CONCLUSION: This pilot suggests similar efficacy and safety but a cost difference favoring APC. A fully powered non-inferiority trial is appropriate to confirm these findings.
