Barrett’s esophagus (BE) might recur after complete eradication of intestinal metaplasia (CEIM). We investigated factors associated with recurrence of BE after successful Radiofrequency ablation (RFA).
A longitudinal study of BE patients with dysplasia treated with RFA from 2014 to 2021 in two large referral centers. Recurrence was identified in histologic specimens. Factors associated with post-RFA recurrence were analyzed using Cox regression analysis.
A total of 728 patients with BE were identified, 118 had underwent RFA, and 113 had sufficient follow up time. Mean age was 63.7 (±11.7) years, 73.5% were males, 59.3% had long segment of BE, and 30.1% had multifocal dysplasia. During 340.8 patient-years of follow-up, 15 patients (13.3%) had recurrence of BE, which represent an incidence rate of 4.41% per patient-year. Incidence rate of recurrence with dysplasia was 1.17% per patient-year. Multifocal dysplasia, number of RFA sessions, and endoscopic resection before RFA were associated with risk of recurrence in univariate analysis. However, in cox regression analysis only multifocal dysplasia (HR 10.99; 95% CI 2.83-22.62, p = 0.001) was associated with post-RFA recurrence.
Total recurrence rates after CEIM are low, and multifocal dysplasia before the ablative therapy is significantly associated with BE recurrence after CEIM. Patients with multifocal dysplasia should be monitored rigorously after successful ablation.
