who had undergone EMR followed by surveillance of residual Barrett's mucosa. The two groups were matched for any potential confounders to minimise bias. Results There were 13 patients in each group. Mean age in the EMR group and EMR+RFA group was 70 and 59 years, respectively. Both groups were equally matched in terms of male to female ration (12:1); length of circumferential Barrett's mucosa; lesion Paris classification; mean lesion size; and resection type (Piecemeal or Enbloc).

... ion of follow-up in the EMR group was 21 months compared to 32 months in the EMR+RFA group. The histological characteristics of lesions in both groups are shown in the table below (Abstract PWE-032 table.1). Overall, histological eradication of EN was achieved in eight (62%) patients in the EMR group and 13 (100%) in the EMR+RFA group at the last follow-up. Persistence or recurrence of EN and the need for further EMR during follow-up occurred in five patients (38%) in the EMR group (two of them had Oesophagectomy) compared to only one (8%) in the EMR +RFA group. One patient (8%) in the EMR group developed oesophageal stricture and no complications occurred in the other group.
