Diagnostic Value of Confocal Laser Endomicroscopy (CelTouch) for Peripheral Lung Lesions
This study uses CelTouch to explore patients with lung lesions scheduled for lung biopsy. By comparing with preclinical CLE images and pathological images, CLE diagnostic criteria for benign and malignant lung lesions under the microscope will be established; the performance of CLE in diagnosing peripheral lung lesions

| Summary | This study uses CelTouch to explore patients with lung lesions scheduled for lung biopsy. By comparing with preclinical CLE images and pathological images, CLE diagnostic criteria for benign and malignant lung lesions under the microscope will be established; the performance of CLE in diagnosing peripheral lung lesions will be validated through multicenter clinical research; and a CLE atlas for peripheral lung lesions will be constructed to establish a visual classification diagnostic system for peripheral lung lesions. (1) Comparative Study of In Vivo CLE Images and Pathological Images in the Diagnosis of Peripheral Lung Lesions 1. Collect CLE images and histopathological sections of clearly diagnosed peripheral lung lesions. 2. A diagnostic team composed of 1 bronchoscopy expert, 1 patho |

Those with contraindications to general anesthesia or bronchoscopy; 2. Patients with uncorrectable coagulation disorders; 3. Unable to discontinue therapeutic anticoagulants within an appropriate time interval before surgery; 4.
