Core Tip

Core tip: Confocal laser endomicroscopy (CLE) enables cellular visualization during on-going endoscopy. Lately, the method has been further refined by using fluorescent labelled molecular probes for estimation of receptors in carcinomas, illumination of subtle lesions and assessment of the affinity of drugs to specific lesions. This article presents the method of molecular CLE and gives a review of the current applications and drawbacks.
