Brief Summary

Solitary pulmonary nodule has become a major challenge in respiratory clinical practice. According to published guidelines, their management often requires close CT follow up, PET CT and invasive procedures to obtain a definite histology. In this context, innovative endoscopic techniques refered as navigational bronchoscopy have proved to be efficient, for the localization and sampling of peripheral lung nodules. However, these techniques are unable to differentiate malignant lesions from benign ones, in-vivo, in real time. Confocal endo-microscopy (CELLVIZIO) of the distal lung - also refered as distal lung probe based confocal laser endo-microscopy or alveolar lung endo-microscopy - allows in-vivo imaging of the distal lung structures in real time. This prospective trial we will assess confocal endoscopy as a tool to localize the peripheral lung nodules and to differentiate benign from tumoral lesions. Objective(s)

  1. 1.To demonstrate that confocal endo-microscopy is not inferior to navigational endoscopy for the localisation of peripheral lung nodule
  2. 2.To demonstrate that confocal endoscopy can differentiate benign from malignant tumors

Outcome Measures

Primary Outcomes (1)

  • Sensitivity of confocal imaging (solid pattern) for the diagnostic of the pulmonary nodule

    Confocal imaging will be considered as "positive" when both * a solid pattern is displayed * a diagnostic biopsy is obtained at the site of confocal imaging

    six months after the procedure

Study Arms (1)

confocal endo-microscopy

EXPERIMENTAL

confocal endo-microscopy : CELLVIZIO endo-microscopy procedure is performed in every patient using the same extended working channel as for navigational bronchoscopy.

Device: confocal endo-microscopy

Interventions

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.

Also known as: CELLVIZIO Lung 488 nm and 660 nm, 1 mm CELLVIZIO miniprobe (ALVEOFLEX), 0.6 mm CELLVIZIO miniprobe (CHOLANGIOFLEX)
