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.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Diagnostic
Fluorescence-aided confocal endomicroscopy guided biopsy., Random four-quadrant biopsies.

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) 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...
This is a confirmatory, multicentric, prospective, randomized, controlled, single-blind study in subjects with long standing ulcerative colitis in clinical remission with indication for su...
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...
The endomicroscopy is an adaptation of traditional optical microscopy in the digestive endoscopy. Furthermore, with the integration of a miniaturized laser confocal microscope to a videoen...
Confocal laser endomicroscopy (CLE) requires fluorescence agents, the use of which leads to blurred images and low diagnostic accuracy owing to fluorescein leakage. We aimed to explore whether mult...
Probe-based confocal laser endomicroscopy (pCLE) is a revolutionary modality that enables "optical biopsy" by enabling real-time imaging of the digestive tract . Application of a fluorescent agent is...
Needle-based confocal laser endomicroscopy (nCLE) enables observation of the inner wall of pancreatic cystic lesions (PCLs) during an endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). ...
Probe-based confocal laser endomicroscopy (pCLE) is an innovative endoscopy that can visualize biological tissues to the cell level by intravenously administering a fluorescent dye. Fluorescein, a flu...
Transbronchial cryobiopsy (TBCB) of the lung parenchyma is a minimally invasive alternative for surgical lung biopsy in interstitial lung disease (ILD) patients. Drawbacks are the nondiagnostic rate a...
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.
Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
