Analysis on clinical features of endobrenchial tuberculosis and classification of bronchoscopic features in 258 cases

Abstract

Objective To analyze the bronchoscopic features of endobronchial tuberculosis(EBTB) and study the classification of bronchoscopic features. Methods The clinical and bronchoscopic features of 258 histopathologically diagnosed patients were retrospectively analyzed. Results The bronchoscopic features of EBTB were thus classified into six types: exudative type 47.3%, ulcerative and caseating type 22. 1%,granular hyperplasy type 16.3%, cicatrical type 9. 7%, lymph-bronchi fistula 3.1%, bronchus collapse type 1.6%. EBTB was more common in upper lobe and superior bronchi of lower lobe (60. 90%).Conclusions It is more reasonable to classify bronchoscopic features of EBTB into the following six types: exudative type, ulcerative and caseating type, granular hyperplasy type, cicatrical type, bronchus collapse type, and lymph-bronchi fistula, which will favor the relevant diagnosis and treatment.
