Primary Outcome Measures:
  • Detection of neoplasia [ Time Frame: 5 years ]

Estimated Enrollment: 500
Study Start Date: June 2009
Estimated Study Completion Date: December 2019
Estimated Primary Completion Date: December 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: endoscopy arm
imaging performed in conjunction with the regularly scheduled endoscopy during which the newer imaging techniques will be used to detect premalignant conditions. includes wide field fluorescence, microscopy, Raman spectroscopy and/or ultrasound.
Device: Dual axis endoscopic microscope
This is a device that is used in the accessory port of a standard endoscope and allows visualization of microscopic areas of mucosa.
Other Name: Stanford
Device: wide field fluorescence system
This is a modification to the existing narrow band endoscope from Olympus that incorporates different filters on the source and collecting optics to enable fluorescence imaging. It is used as is a standard endoscope.
Other Name: Olympus
Device: CellVizio
Minimicroscope--this is an FDA approved fiber-based microscope that we will use according to the manufacturers protocols.
Other Name: Mauna Kea Technologies
Drug: fluorescent Peptide
microdosing; Topical through the endoscope
Other Name: GMP
Drug: fluorescein
100 mcg topical
Other Name: fluorophore
Drug: indocyanine green
100 mcg topical
Other Name: ICG


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:patients be at least 18 years of age,

Either genders

All ethnic backgrounds will be considered.

Patients who are scheduled for endoscopy by one of the investigators will be asked if they are interested in participating in the study.

The study will be open to all patients undergoing endoscopy that do not have exclusion criteria. We will ask all patients if they are participating in any other studies. If they are participating in any other study then we will ask them for more information to determine whether there could be any harm from participating in both studies and if there is then they will not be enrolled.

Exclusion Criteria:Patients with unstable vital signs will not be included.
