Abstract:
Objective:To explore the effectiveness and safety of holmium laser treatment via flexible bronchoscopy in children with tracheobronchial tuberculosis (TBTB).Methods:The clinical data of 40 children with TBTB admitted in Qilu Children′s Hospital of Shandong University from February 2016 to June 2019 were retrospectively analyzed. According to the treatment approach, they were divided into conventional treatment group (20 cases) and holmium laser treatment group (20 cases). The sex, age, course of disease and lesion location before treatment, and the time till relief of atelectasis and airway obstruction after treatment were compared between the two groups with t test and χ 2 test. Results:Among the 40 cases, 24 were males and 16 females, and 35 had lymph node fistula (87.5%) and 5 had granulation proliferation (12.5%). There was no statistically significamt difference between the conventional group and laser group in sex (male ratio: 50%（10/20） vs. 75%（15/20）, χ 2=2.66, P=0.10), age （(3.2±2.2） years vs. （2.2±1.8） years, t=1.41, P=0.16), course of disease (<1 month ratio: 30%（6/20） vs. 35%（7/20）, χ 2=0.11, P=0.73), lesion location (single lesion ratio： 45%（9/20） vs. 60%(12/20), χ 2=0.90, P=0.34). The effectiveness was evaluated after 3 months, and the total effective rate were 100% in laser group and 40% in conventional group, the difference was significant (χ2=25.34, P<0.01). No serious adverse events occurred in the two groups during the observational period. Conclusions:Holmium laser treatment via bronchoscopy is an effective way to remove the tuberculosis foci in the trachea, which can reduce the incidence of further related complications, and could be applied in clinical approach.
