Pilot Study to Evaluate OFDI Surveillance and Image Guided Biopsy of the Esophagus
Twenty four consenting patients undergoing esophagogastroduodenoscopy (EGD) surveillance
following a confirmed diagnosis of Barrett's esophagus will be recruited at Massachusetts
General Hospital (MGH) . Along with Optical Frequency Domain Imaging (OFDI) imaging and
cautery marking for targeted biopsy, the patients will undergo a standard of care clinical
Esophagogastroduodenoscopy (EGD) procedure including endoscopic random biopsy. This study
requires the use of a balloon catheter which is a commonly used technique and is accepted in
clinical practice for dilation of esophageal and colonic strictures and for photodynamic
therapy.
Once in position, the OFDI tissue marking laser will be activated by the physician. The
physician will control the marking and make two marks of a duration of 2 seconds each. The 2
seconds time period will limit the tissue effects to only the superficial layers of the
esophageal mucosa.
It is expected that the total experimental time including insertion and inflation of the
OFDI balloon catheter, OFDI imaging, tissue marking, and removal of the OFDI balloon will
add approximately 15 minutes to the total length of the EGD.

Feasibility and specificity of OFDI marking and imaging
Determination of the feasibility to mark targeted pathologic locations identified through OFDI imaging using superficial cautery marks.Verification by endoscopy and utilization of the marks for biopsy guidance.Images will be analyzed and compared to biopsies of the correlated marked tissue.
Images will be acquired during the OFDI imaging session which should take an average of 5 mintues
