摘要: Barrett's esophagus has been a focus of confocal laser endomicroscopy (CLE) research. There are two CLE systems available, one probe-based and the other with microscope embedded in tip an endoscope. Several image classification available. Studies suggest that good sensitivity, negative predictive value, accuracy for detecting neoplasia, interobserver agreement using systems. Larger, multicenter studies have completed evaluating impact on treatment patients BE. Future developments may include more specific contrast agents new types endomicroscopes.
