Tethered capsule endomicroscopy for Barrett's esophagus surveillance following endoscopic eradication therapy: an exploratory study on patient acceptability (Conference Presentation)

Patients with Barrett’s esophagus (BE) treated with eradication therapy require yearly endoscopic surveillance to monitor for recurrent disease. Tethered capsule endomicroscopy (TCE) is a swallowable optical coherence tomography device designed for microscopic, cross-sectional imaging of the human esophagus and used in BE screening. We explore the acceptability of TCE as an alternative to endoscopy for BE surveillance following eradication therapy. In a cohort of 33 patients, most (79%) successfully swallowed the TCE device and were somewhat to extremely likely to prefer TCE over endoscopy and willing to undergo TCE again in the future. OCT features of BE were observed in TCE scans in 10 (38.5%) patients.
