Confocal Laser Endomicroscopy as a Guidance Tool for Pleural Biopsies in Malignant Pleural Mesothelioma.
Pleural biopsies in patients with suspected malignant pleural mesothelioma (MPM) are often inconclusive resulting in repeat diagnostic procedures. Confocal laser endomicroscopy (CLE) enables real-time imaging on a cellular level. We investigated pleural CLE imaging as a biopsy guidance technique to distinguish malignant from benign pleural disease. ⋯ CLE imaging was feasible and safe regardless of the biopsy method. Real-time visualization of pleural abnormalities in epithelial and sarcomatoid MPM could be distinguished from pleural fibrosis. Therefore, CLE has potential as a guidance biopsy tool to reduce the current substantial rate of repeat biopsy procedures by identification of areas with malignant cells in vivo (smart needle).
