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 endomicro...

Confocal Laser Endomicroscopy (CLE) in Patients With Diarrhea

The main objective of this study is to determine the frequency of different gastrointestinal disorders as the cause of diarrhea in patients at a tertiary referral center using confocal las...

Confocal Laser Endomicroscopy in Pleural Malignancies

To date, the different biopsy methods, such as CT-guided pleural biopsy, mediastinal biopsy, endosonography and thoracoscopy have their limitations in diagnosing pleural malignancies, such...

Confocal Laser Endomicroscopy (CLE) During Medically Induced Neurosurgery in Craniobasal and Glioma Tumours

Purpose of the study is to answer the question whether confocal laser endomicroscopy (CLE, also named 'optical biopsy') might improve the results of medically necessary neurosurgery to pro...

Confocal Laser Probe to Treat Barrett's Esophagus

The purpose of this study is to further validate the use of probe-based confocal laser endomicroscopy (pCLE) for the evaluation of Barrett's Esophagus and associated neoplasia in a larger ...

High prevalence of gastric intestinal metaplasia detected by confocal laser endomicroscopy in Zambian adults.

Confocal laser endomicroscopy (CLE) may increase the detection of gastric premalignant lesions, and facilitate targeted biopsies for histology. The study aim was to analyse premalignant lesions in Zam...

Probe-based Confocal Laser Endomicroscopy in Metastatic Pulmonary Calcification.

We report a case of metastatic pulmonary calcification in a patient with chronic renal failure on hemodialysis and secondary hyperparathyroidism. The diagnosis was made by using a probe-based confocal...

Development and Validation of a Confocal Laser Endomicroscopy-Based Score for In Vivo Assessment of Mucosal Healing in Ulcerative Colitis Patients.

Endoscopic monitoring is fundamental for evaluating the therapeutic response in IBD, but a validated endomicroscopic mucosal healing (MH) score is not available to date. However, confocal laser endomi...

Optical Screening of Novel Bacteria-specific Probes on Ex Vivo Human Lung Tissue by Confocal Laser Endomicroscopy.

Improving the speed and accuracy of bacterial detection is important for patient stratification and to ensure the appropriate use of antimicrobials. To achieve this goal, the development of diagnostic...

Identifying a mucinous neoplasm utilizing confocal laser endomicroscopy: branch-duct gastric type intraductal papillary mucinous neoplasm.

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).

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.

The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.

Tumors or cancer of the URINARY BLADDER.

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.
