    Detection of buried Barrett’s glands after radiofrequency ablation with volumetric laser endomicroscopy

    Background and Aims The prevalence and clinical relevance of buried Barrett’s glands (BB) after radiofrequency ablation (RFA) in Barrett’s esophagus (BE) are debated. Recent optical coherence tomography studies demonstrated a high prevalence of BBs. Direct histological correlation, however, has been lacking. Volumetric laser endomicroscopy (VLE) is a second-generation optical coherence tomography system capable of scanning a large surface of the esophageal wall layers with low-power microscopy resolution. The aim was to evaluate whether post-RFA subsquamous glandular structures (SGSs), detected with VLE, actually correspond to BBs by pursuing direct histological correlation with VLE images. Methods In vivo VLE was ...
