Laryngeal Leiomyoma, Probe-based Confocal Laser Endomicroscopy
Conditions
Keywords
Probe-based confocal laser endomicroscopy, Optical biopsy
Brief summary
To evaluate the diagnosis of laryngeal lesions using the Probe-based Confocal Laser Endomicroscopy in vivo.
Detailed description
In this study, we will conduct in-vivo confocal laser endoscopic imaging studies of laryngeal and precancerous lesions to explore the value of pCLE in the diagnosis of laryngeal cancers.
Interventions
Confocal laser microendoscopy (CLE) as a new non-invasive imaging technique can be used for optical biopsy, which can perform real-time microscopic information of tissue in vivo at cellular level with resolutions up to 1μm and magnifications up to 1000 times. CLE is now being increasingly used with very promising results in gastroenterology, especially in the diagnostic investigation of Barret's esophagus, stomach cancer, colorectal cancer and various lesions of the biliary tract. With an intravenous injection of fluorescein, probe-based CLE (pCLE: GastroFlex probe with the Cellvizio laser system, Mauna Technologies, Paris, France) allows us to view the interstitial spaces, cells, and small capillaries in a window of 240 μm and to a depth of 60 μm.
