Confocal Laser Endomicroscopy in Digestive Diseases
Confocal laser endomicroscopy (CLE) is a newly endoscopic device that enables microscopic view of the digestive tract. The purpose of this study is to determine if confocal laser endomicroscopy can improve detection of digestive disease include inflammation, dysplasia, and early cancer, and if confocal laser endomicroscopy has competitive advantage, compared with other device such as Narrow Band Imaging and Autofluoresecence Imaging.
Advances in endoscopy have led to imagining of the details of digestive mucosa. Novel techniques such as Narrow Band Imaging (NBI) assisted magnification endoscopy, Auto Fluorescence Imaging (AFI) or confocal laser endomicroscopy could, however, improve the endoscopic detection.In this research we describe the combined use of these three techniques in patients with digestive disease.

Medical and Biotech [MESH] Definitions
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
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.
Angioplasty, Balloon, Laser-assisted
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Laser Therapy, Low-level
Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
