Novel Imaging Techniques in Barrett's Esophagus

"Narrow Band Imaging- Patients will be evaluated with a standard magnification endoscope (Olympus GIF Q240Z, 115x or GIF-H180 or equivalent) using a NBI light source.Target biopsies with standard biopsy forceps will be obtained from the different visualized patterns in separate jars.~Autofluorescence Imaging- Patients will be evaluated using a prototype autofluorescence endoscope (Olympus, Tokyo, Japan; excitation 395-475 nm, fluorescence detection 490-625 nm, red reflectance 600-620 nm and green reflectance 540-560 nm).In this system, normal squamous and non-dysplastic BE appears green while the dysplastic areas appear magenta/purplish. Targeted biopsies will be obtained from the areas with abnormal fluorescence."

Standard Endoscopy- Patients will undergo EGD with biopsies using a standard diagnostic video endoscope (Olympus, GIF 140 or 160) using the Seattle protocol - 4 quadrant biopsies using standard biopsy forceps every 2 cms; stored in separate jars.
