Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Probe based confocal laser endomicroscopy (pCLE) is a new optical endoscopic technique, generating fluorescent light emission from the tissue of interest and allowing in vivo live imaging at a cellular level ("optical biopsies"). It was first used in gastroenterology and came later to the light in pulmonary medicine and is still an experimental technique. In gastroenterology, this new investigational technique is used in Barret oesophagus, inflammatory bowel disease, pancreas cystic lesions... Nowadays, there are no data concerning usefulness of endomicroscopy in medical thoracoscopy. During thoracoscopy This new tool could help to target biopsies or help clinicians to do the right diagnosis early, allowing rapid therapeutic intervention (talc pleurodesis for example) . Furthermore, some details can be studied only during live imaging as microorganisms or bloodflows. The investigators performed an endomicroscopy to every patient needing a thoracoscopy (no matter the indication) and who agreed to participate. The pCLE features between malignant and benign pleura were compared in order to find specific criteria for malignant infiltration.
