Abstract:

Objective To analyze the factors affecting the efficacy in patients with ulcerous necrotic type bronchial tuberculosis.Methods A total of 105 cases who were first diagnosed with ulcerous necrotic type bronchial tuberculosis by bronchoscopy in the Department of Tuberculosis in Tongji University affiliated to Shanghai Pulmonary Hospital were successively collected from January 2016 to January 2018, and were set as subjects. The clinical data of the patients were collected, and the lesion involved airway sites and levels, the degree of lumen stenosis caused by necrotic materials and mucosal edema, and the imaging characteristics of the chest CT scan under bronchoscopy were recorded.Results Among the 105 patients with ulcerous necrotic type bronchial tuberculosis, 72 cases (68.6%) were effectively treated, and 33 (31.4%) were ineffectively treated. In the ineffective treatment group, 12 cases (36.4%) had a smoking history, 21 cases (63.7%) had a symptom duration (from onset to treatment) ≥ 4 weeks, 10 cases (30.3%) had cavity on chest CT scan, and 12 cases (36.4%) had a lesion involved airway level ≥3. In the effective treatment group, the case numbers of the above four outcomes were 12 (16.7%), 24 (33.3%), 8 (11.1%) and 10 (13.9%), respectively. The differences between the two groups were statistically significant (χ 2=4.98, 8.49, 5.87 and 6.90, respectively, all P values were <0.05). Multivariate logistic regression analysis showed that the smoking history (OR=2.87, 95%CI: 1.01-8.14), symptom duration ≥ 4 weeks (OR=3.48, 95%CI: 1.35-9.01), cavity on chest CT scan (OR=3.27, 95%CI: 1.02-10.55), the lesion involved airway levels ≥ 3 (OR=3.73, 95%CI: 1.23-11.31) were risk factors for the ineffective treatment of ulcerous necrotic type bronchial tuberculosis.Conclusion The strengthening smoking cessation education, enhancement of publicity and education on tuberculosis prevention, and early diagnosis and treatment may contribute to improve the treatment efficiency for the ulcerous necrotic type bronchial tuberculosis.
