Abstract
Background This study aimed to evaluate the use of ultrahigh-speed volumetric en face and cross-sectional optical coherence tomography (OCT) with micromotor catheters for the in vivo assessment of Barrett's esophagus and dysplasia. Methods ?74 OCT datasets with correlated biopsy/endoscopic mucosal resection histology (49 nondysplastic Barrett's esophagus [NDBE], 25 neoplasia) were obtained from 14 patients with Barrett's esophagus and a history of dysplasia and 30 with NDBE. The associations between irregular mucosal patterns on en face OCT, absence of mucosal layering, surface signaľ>subsurface, anď>5 atypical glands on cross-sectional OCT vs. histology and treatment history were assessed by three blinded readers. Results ?Atypical glands under irregular mucosal patterns occurred in 75% of neoplasia (96% of treatment-naïve neoplasia) vs. 30% of NDBE datasets (43% of short- and 18% of long-segment NDBE). Mucosal layering was absent in 35% of neoplasia and 50% of NDBE datasets, and surface signaľ>subsurface occurred in 29% of neoplasia and 30% of NDBE datasets. Conclusions ?Atypical glands under irregular mucosal patterns are strongly associated with neoplasia, suggesting potential markers for dysplasia and a role in pathogenesis. © 2019 Georg Thieme Verlag KG Stuttgart New York.
