Optical Frequency Domain Imaging (OFDI) Assessment in Radiofrequency Ablation (OFDI)
Pilot Study to Evaluate Optical Frequency Domain Imaging as a Tool for Assessing the Tissue Response to Radiofrequency Ablation
연구 개요
상세 설명
This is a single center pilot study conducted in 30 patients scheduled for therapeutic intervention. As the purpose of the study is to assess the response of the esophagus to radio frequency (RF) ablation, and the degree of residual Barrett's Esophagus (BE) remaining following treatment, OFDI imaging of study participants will occur prior to the scheduled BARRX RF treatment, and at the standard 3 and 6 month follow-up visits.
Following initial visual surveillance of the esophagus, the study experimental procedure will begin. Imaging will be performed with the OFDI system in 4 longitudinal (~5cm) volumetric segments that are spaced equally circumferentially along the esophagus in a similar fashion to the standard 4-quadrant biopsy protocol.
Each of the 4 OFDI imaging segments will be acquired in less than 1 minute.

Feasibility of OFDI Imaging as Determined by Number of Successful Imaging Sessions
기간: During the OFDI imaging session (about 5 minutes)
|
Images will be taken and compared to standard of care biopsy to assess the success and degree of injury associated with radiofrequency ablation techniques.
A successful imaging session is defined as any session where the OFDI device was able to take and produce discernible and clear data that is comparable to corresponding biopsy histopathology.
It is considered unsuccessful if we were unable to produce OFDI data and/or attain a corresponding biopsy.
