Abstract:
Objective:To analyze the factors affecting the disappearance time of airway necrosis and repair time of airway scar stenosis in patients with ulceration necrosis tracheobronchial tuberculosis (TBTB Ⅱ) after standardized chemotherapy and bronchoscopic intervention.Methods:The clinical data of 222 TBTB Ⅱ patients admitted to Hunan Chest Hospital from January 2015 to December 2018 were collected, bronchoscopic interventional treatment was performed on time. The texture, blockage of lumen, granulation proliferation, airway stenosis of TBTB patients before treatment, the disappearance time of airway dead objects, scar repair time and stenosis degree after treatment were followed up. The disappearance time of airway necrosis and repair time of airway scar stenosis and its influencing factors were recorded and analyzed.Results:In 222 patients, 508 ulceration necrosis airway lesions were found under bronchoscopy, with a median of 2(1-6); 170(76.6%) cases of airway lesions had different degrees of stenosis before treatment. 79(35.6%) patients had tough necrosis, and 86(38.7%) patients had necrosis blocking the lumen; 132(59.5%) patients had granulomatosis. The disappearance time of airway necrosis after treatment was 1 to 32 weeks, and M( Q1, Q3) was 6(3, 9) weeks; the repair time of airway scar stenosis was 2 to 73 weeks, and M( Q1, Q3) was 14(10, 19) weeks; after treatment, there were 90.5%(201/222) patients with different degrees of scarring in the airways. Cox multiple analysis showed that the risk factor for the disappearance time of airway necrosis was tough tough necrosis ( HR=1.52, 95% CI: 1.10-2.10); the risk factor for the repair time of airway scar stenosis was the disappearance time of airway necrosis 6-9 weeks ( HR=2.73, 95% CI: 1.84-4.05). Conclusions:90.5% of patients with type Ⅱ TBTB developed airway scar stenosis after treatment. The median time for the disappearance of airway necrosis was 6 weeks, and the median time for the repair time of airway scar stenosis was 14 weeks. In the interventional process, attention should be paid to the removal of tough necrosis and the efficiency of necrosis removal to reduce the risk of airway scar stenosis.
