Background: Endobronchial tuberculosis is one of serious complication of pulmonary tuberculosis and may result from rupture of infected lymph nodes into the bronchial wall or from lymphatic spread to the mucosal surface of the bronchial tree. It is a major cause of morbidity, as it heals with concentric scarring, resulting in bronchial stenosis, atelectasis, and frequently recurring pneumonia. The clinical and bronchoscopic features of endobronchial tuberculosis retrospectively investigated.
Materials and methods: Total 86 cases with endobronchial tuberculosis out of 666 subjects, who had flexible bronchoscopic examination at the department of internal medicine, Soonchunhyang Gumi hospital during the period between the beginning of March 1996 and October 2003, were included in the study. The diagnostic criteria used for endobronchial tuberculosis included the cases proven as tuberculosis by culture of bronchial washing and histologic features of biopsy specimen among patients with endobronchial lesion on bronchoscopy. Clinical information was retrospectively gathered from all available medical records.
Results: The peak incidence of endobronchial tuberculosis coourred in the third decade. The incidence of female was 4.1 times higher than that of male. Chronic cough was the most common chief complaint(41.9%). Parenchymal infiltration and/or consolidation of lung was the most common chest X-ray finding(53.5%). Caseaous necrosis was the most common bronchoscopic finding(37.2%). The most frequently involved bronchus was the right upper lobar bronchus(31.3%) and in case of including left upper bronchus, involvement of upper lobar bronchus was 53.4%.
Conclusion: The annual incidence of endobronchial tuberculosis didn’t decrease from the end of 20th century to the beginning of 21st century. Thus, when young female patients complain of chronic cough, bronchoscopy should be considered to differentiate endobronchial tuberculosis.
