Abstract:

Objective: To investigate the features of inactive central tracheobronchial tuberculosis (tracheobronchial tuberculosis) using different types of microscopes. Methods: The clinical manifestations, imaging features, and bronchoscopic findings of 267 tracheobronchial tuberculosis patients admitted to Beijing Chest Hospital from January 2017 to December 2020 were retrospectively analyzed. Results: Of the 267 cases, 79 were male and 188 were female, the ratio of male to female was 1∶2.38; and the patients were mainly 20-40 years old (55.43%, 148/267). Common symptoms were dyspnea (221 cases, 82.77%), cough and sputum (166 cases, 62.17%), fever (35 cases, 13.11%), hemoptysis (15 cases, 5.62%), and non-symptoms (20 cases, 7.49%). The main involved parts of inactive tracheobronchial tuberculosis were left principal bronchus (124 cases, 46.44%), right intermediate bronchus (69 cases, 25.84%), right principal bronchus (48 cases, 17.98%), trachea (26 cases, 9.74%), the ratio of left to right was 1∶0.94 (124∶117). Among the total 267 cases, 21 were soft type (7.87%), 198 were stenotic type (74.16%), 15 were occlusion type (5.62%), 33 were frequent retraction type (12.36%); 169 complicated with atelectasis (63.30%), 116 complicated with pulmonary cavitation (43.45%), and pulmonary multiple niduses was found in 195 cases (73.03%). The coincidence rate of bronchial luminal stenosis between CT scan and bronchoscope was 98.13% (262/267). Conclusion: Inactive tracheobronchial tuberculosis is common in women, middle-aged and young people. The most common symptoms are dyspnea, cough and sputum. The coincidence rate of CT scan is high, and CT scan is an important diagnostic method before bronchoscopy.
