Features of Sub-Epithelial Glandular Structures on Three-Dimensional Endoscopic Optical Coherence Tomography (3D-EOCT) After Endoscopic Mucosal Ablation
Abstracts submitted to ASGE 2010. Endoscopic mucosal ablative therapies are becoming accepted as a treatment for Barrett's esophagus (BE) with high-grade dysplasia. Radiofrequency ablation (RFA) has been shown to be effective in achieving broad and superficial BE ablation and replacement with normal-appearing squamous epithelium. Endoscopic optical coherence tomography (EOCT) is an imaging technique that uniquely allows visualization of sub-surface structures. The new three-dimensional EOCT (3D-EOCT) provides both cross-sectional and en face images of examined structures. 3D-EOCT may represent a novel method for post-ablation BE surveillance by revealing different glandular structures underneath the post-ablative surface epithelium.
