This is the largest reported Australian cohort. Patients referred to St Vincent’s

& Royal Melbourne Hospitals from 2008-September 2012 for endoscopic treatment of BE were entered prospectively into a central database. Patients underwent assessment find more endoscopy with white light, narrow band +/− confocal endomicroscopy and had EMR of any visible lesions. Subsequent staging investigations (endoscopic ultrasound/PET/CT), management and histological outcomes were recorded. Patients deemed appropriate for RFA (treatment group) were treated at ∼3 monthly intervals until remission of dysplasia (CR-D) and/or Barrett’s (CR-BE) was achieved. Patients underwent further EMR if visible lesions persisted. Remission rates were assessed for CR-D (=no dysplasia on biopsy) and CR-BE (=no intestinal metaplasia on biopsy and no macroscopic BE). Time to achieve 5-FU nmr remission and number of RFA treatments required to reach these endpoints were also recorded. Adverse events were defined as surgery, hospital admission, bleeding requiring blood transfusion or unplanned endoscopic intervention. 164 patients were referred. 35 were assessed not

suitable for combined endoscopic therapy (CET) due to advanced disease (24), non-dysplastic BE (8) or comorbidities (3). 6 await assessment. Of 123 amenable to CET, 16 await treatment, 13 have had EMR only. There were 94 patients (80M) in our treatment group (RFA+/−EMR (34)). Median age of this group was 66 (39-85); median M length 5cm (0-18); 67 (71%) had HGD or IMC as worst prior pathology. Kaplan-Meier

Tideglusib analysis shows 96% of the treatment group achieved CR-D within 30m and 81% achieved CR-BE within 36m. Median time to CR-D was 7.4m (0.4-29.2), median RFA=2 (1-6). Median time to CR-BE=12.4m (2-34.4); median RFA=2(1-6). Of 138 EMR procedures there was one perforation requiring surgery and seven hospital admissions for observation. Of 202 RFA procedures there were 5 complications requiring admission (2 post-RFA bleeds). Our data supports that RFA combined with EMR is effective in achieving CR-D and CR-BE in the majority of patients with dysplastic BE and offers an alternative to surgery with low risk of serious complication. Ongoing follow-up of this cohort is needed to determine durability of treatment. There exists a subgroup of patients with dysplastic BE who have poorer response to RFA. Further studies are needed to determine risk factors for poor responders. “
“Subsquamous intestinal metaplasia (SSIM) is defined as metaplastic columnar tissue found beneath an overlying layer of intact squamous epithelium. SSIM occurs in >25% of those with dysplastic Barrett’s esophagus (BE), and in 5% or more of patients following radiofrequency ablation (RFA) for BE. We assessed the predictors of SSIM in a nationwide RFA registry. The U.S. RFA Registry is a prospective study of subjects with BE treated with RFA at 148 institutions.
