This study is an analysis of clinical factors and treatment for tracheo-bronchial stenosis following tracheo-bronchial tuberculosis. The patients were classified into two groups according to whether they were treated or not. Group A was not treated specifically for stenosis and Group B was treated by endoscoic and surgical procedures. The average age of detection of tracheo-bronchial tuberculosis in Group A was fifteen years older than that in Group B. In both groups the disease was detected in two thirds of the cases due to symptoms. The lesions of tracheo-bronchial tuberculosis were detected earlier in Group A than Group B in the cours of disease. Secondary changes(atelectasis and/or obstructive pneumonia)were found in chest X-rays in 29.6% (42/142) of Group A and in 58% (36/62) of Group B. Group A was treated by anti-tuberculous chemotherapy (137/142). In Group B 10 of 60 cases received endoscopic treatment and 52 cases were treated by surgery, among which 30 underwent tracheal and bronchial reconstruction. As a result of this treatment, bronchoscopy and chest X-ray showed that an improvement of stenosis was found in 70 patients of Group A. In 15 patients there was deterioration and 12 patients showed no change. However, in 40 patients findings remain unknown without further assessment. In Group B, 5 of 10 patients of endoscopic therapy improved and 50 of 52 patients returned to regular work.
