Sa1074 Increased Number of Risk Factors Predicts Esophageal Injury and Metaplasia: Results From a Large Prospective Population-Based Study

Abstract

modalities were included in this analysis. Patients who stopped EET and started surveillance prior to CE-IM were excluded. Complete eradication of intestinal metaplasia (CE-IM) was defined as having an endoscopy with no visible columnar lined epithelium in the tubular esophagus and biopsies of the neo-squamous mucosa showing no intestinal metaplasia. Patients were considered to have achieved CE-IM if they had done so with 2cm were less likely to achieve CE-IM compared to those with C extents ≤2cm (64.3% vs. 73.5%, p=0.027). Patients with M extents of > 3cm were less likely to achieve CE-IM compared to those with M extents ≤3cm (61.2% vs. 88.4%, p<0.001). Conclusions: Results of this multi-center effectiveness trial show that pre-treatment Barrett's esophagus extent as measured by the Prague criteria is associated with the rate of achieving CE-IM with endoscopic eradication therapy. This was true for both the C and M extents of disease. This study provides the first validation of the Prague criteria with clinically relevant outcomes in the management of patients with Barrett's esophagus.
