Abstract:

Objective To investigate the application value of interventional bronchosopic techniques in treating the middle lobe syndrome due to tracheobronchial tuberculosis.Methods The date of 118 cases who were diagnosed the middle lobe syndrome due to tracheobronchial tuberculosis from November 2015 to December 2017 in the 8th Medical Center of Chinese PLA General hospital were analyzed retrospectively. The patients were divided into discovery group (n=82) and control group (n=36) by different treatment schedules. The asymptomatic, imaging appearances, bronchoscopy, ratings of short breath and effects of treatment were compared between the two groups.Results The ratings of short breath at 6 months after discharge in the discovery group and control group was (0.74±0.12) and (1.36±0.07), respectively, and the difference was statistically significant (t=2.791,P=0.006). The overall effective rate in the two groups was 80.5% (66/82) and 61.1% (22/36), respectively, and the difference was statistically significant (χ ²=12.743, P= 0.002). Conclusion The interventional bronchoscopic technique is an important treatment of patients with middle lobe syndrome due to tracheobronchial tuberculosis, and can improve the effective rate.
