Characterization of buried glands before and after radiofrequency ablation by using 3-dimensional optical coherence tomography (with videos)

摘要

BackgroundRadiofrequency ablation (RFA) is an endoscopic technique used to eradicate Barrett’s esophagus (BE). However, such ablation can commonly lead to neosquamous epithelium overlying residual BE glands not visible by conventional endoscopy and may evade detection on random biopsy samples.
