- W3002689208 abstract "Abstract Background Radiofrequency ablation (RFA) can eradicate dysplasia and intestinal metaplasia in patients with dysplastic Barrett's oesophagus (BO). This study aimed to determine the factors that affect response to RFA for BO with dysplasia in a tertiary metropolitan referral centre. Methods All patients with dysplastic BO treated with regular proton pump inhibitor twice a day and RFA from November 2008 to July 2019 were identified. These patients were sorted into good responders (GR) (defined as eradication of dysplasia and intestinal metaplasia within three or less treatment sessions) and poor responders (PR) (defined as patients requiring four or more treatment sessions). The following features were compared between the groups: age, gender, presence of hiatus hernia, hiatus hernia size, circumferential and maximal length of BO, grade of dysplasia on histology at referral and presence of endoscopically visible reflux oesophagitis. Results A total of 152 patients received RFA for dysplastic BO, of whom 125 (82%) patients were classified as GR and 27 (18%) patients were classified as PR. PR had a longer circumferential length of BO compared to GR (mean length of 8.3 versus 3.3 cm, P < 0.0001). PR also had a longer maximal length of BO compared to GR (mean length of 8.7 versus 4.8 cm, P < 0.0001). More patients had reflux oesophagitis identified on gastroscopy in the PR group compared to GR group (12 (44%) versus 20 (16%), P = 0.001). Conclusion Factors such as circumferential and maximal length of BO and presence of reflux oesophagitis on gastroscopy are associated with poorer response to RFA." @default.
