Assessment of Probe Based Confocal Laser Endo-microscopy for In-vivo Diagnosis of Peripheral Lung Nodules and Masses.

The intervention consists of the use of confocal endo-microscopy using the CELLVIZIO device and either the 1 mm CELLVIZIO miniprobe (ALVEOFLEX) or the 0.6 mm CELLVIZIO miniprobe (CHOLANGIOFLEX), during a navigational bronchoscopy procedure for the diagnostic of peripheral nodule. In this study, the navigational device - either radial endobronchial ultrasound (EBUS) or electromagnetic navigation (EMN) - will be moved to another location if the CELLVIZIO displays a non solid pattern, indicating that the nodule may not have been reached during the procedure. Three attempts of EBUS or EMN are allowed until the CELLVIZIO shows a solid pattern.
