摘要
Introduction Endoscopic resection (ER) followed by Radiofrequency ablation (RFA) is the first line treatment for neoplastic Barrett’s oesophagus (BE). Metachronous neoplasia after focal eradication of disease is ~20%. We examine data from the UK registry of 28 centres to establish if residual metaplastic BE carries a risk of disease recurrence. Methods Visible lesions were removed by EMR. Patients then underwent RFA 3 monthly. Biopsies were taken at 12 months to assess treatment success with repeat biopsies every 6–12 months thereafter. Dysplasia recurrence was compared in patients who had complete reversal of BE and neoplasia (CR-IM) to those in whom dysplasia alone was eradicated (CR-D only). Residual BE was confirmed with visible columnar epithelium proximal to the OGJ with biopsies showing IM. Results 517 patients achieved CR-IM u0026 96 patients achieved CR-D only after 12 months treatment . Sex u0026 ER rates were not significantly different between groups. The CR-D only group were older (mean age 70 vs 67, p Conclusion Endotherapy should aim to clear neoplasia and underlying metaplastic BE to improve long term outcome. Patients with CR-D but not CR-IM at the end of treatment have an increased risk of neoplasia recurrence. This may have implications for post treatment surveillance intervals.
