简介
BACKGROUND
Radiofrequency 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.
OBJECTIVE
To demonstrate the capability of endoscopic 3-dimensional optical coherence tomography (3D-OCT) for the identification and characterization of buried glands before and after RFA therapy.
DESIGN
Cross-sectional study.
SETTING
Single teaching hospital.
PATIENTS
Twenty-six male and 1 female white patients with BE undergoing RFA treatment.
INTERVENTIONS
3D-OCT was performed at the gastroesophageal junction in 18 patients before attaining complete eradication of intestinal metaplasia (pre–CE-IM group) and in 16 patients after CE-IM (post–CE-IM group).
