Abstract:
Objective: To evaluate the diagnostic value of transbronchial lung biopsy (TBLB) via bronchoscope for lung diffuse lesions and peripheral pulmonary lesions. Methods: The results of TBLB were retrospectively analyzed from 256 diagnoses of unknown patients with lung diffuse lesions or peripheral lung lesions. Results: Eighty-nine final diagnosis cases via TBLB only once, the diagnostic rate of double lung diffuse lesions was the highest, [51.06%(24/ 47)], local non-nodule lesions, nodule lesions, cavity lesions were 33.33%(23/69), 29.91%(35/117), and 28.57% (4/14), respectively. Among 24 diagnostic cases of double lung diffuse lesions, there were 6 cases of pneumonia of pulmonary tuberculosis, 9 cases of lung carcinoma, 7 cases of adenocarcinoma; 6 cases of pneumonia, 2 cases of fungous infection, and 1 case of lung hemosiderosis. The diagnostic yield about 58 cases of local lesions was low, among which non-nodule lesions accounted for 33.33% and nodule lesions accounted for 29.91%. In 89 cases of peripheral lung lesions with histological diagnosis, lung carcinoma and pulmonary tuberculosis were frequent diseases, which accounted for 86.52%. Conclusion: TBLB is a reliable, safe, effective and repeatable operation method in diagnosis of lung diffuse lesions and peripheral pulmonary lesions.
