2023 World Conference on Lung Cancer (Posters)-EP05.01. Observation of Peripheral Airways Using Ultra-Thin Fiberscope

Pdf Summary

This presentation discusses the use of an ultra-thin fiberscope to observe peripheral airway lesions in the lungs. Currently, the diagnosis of these lesions relies on computed tomography scanning, and endoscopic observation is rarely performed. Although new technologies have been introduced to improve the diagnostic performance of bronchoscopy for peripheral lesions, the yield of bronchoscopic biopsy for these lesions is low. <br /><br />The researchers have developed a 0.97 mm diameter ultra-thin optical fiberscope that can access the peripheral lung fields of human lungs. They used this fiberscope to successfully observe peripheral airway lesions in resected human lungs. In normal, non-smoker's lungs, the fiberscope was able to visualize individual alveoli beyond the respiratory bronchioles. In a case with peripheral lung cancer, alveolar structures were destroyed and replaced with red tumors. In a lung specimen with interstitial pneumonia, extensive neovascularization was appreciated, with destruction of alveoli and thickening of the interstitium.<br /><br />This study represents the first report regarding the use of a fiberscope to observe human lung lesions at the alveolar level. The fiberscope also has the capability to perform simultaneous observation and laser treatment, providing a novel opportunity for treatment of peripheral lesions. <br /><br />The keywords associated with this presentation are: ultra-thin fiberscope, alveolus, and bronchoscopy. The research falls under the track of screening and early detection.
