A Trial Comparing Yield of Confocal Endomicroscopy Guided Biopsies

2014-08-27 03:17:20 | BioPortfolio


We wish to determine whether biopsies obtained with the technique of fluorescence-aided confocal endomicroscopy will detect more patients with specialized columnar epithelium than random biopsies among patients with Barrett's esophagus who are being monitored with endoscopy.

Medical and Biotech [MESH] Definitions

Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.

Fluorescence microscopy utilizing multiple low-energy photons to produce the excitation event of the fluorophore. Multiphoton microscopes have a simplified optical path in the emission side due to the lack of an emission pinhole, which is necessary with normal confocal microscopes. Ultimately this allows spatial isolation of the excitation event, enabling deeper imaging into optically thick tissue, while restricting photobleaching and phototoxicity to the area being imaged.

A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.

Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.

Measurement of the intensity and quality of fluorescence.
