ABSTRACT

Objective To explore the efficacy and safety of the fiberoptic bronchoscope high frequency endotherm knife combined with balloon dilatation in treating tuberculosis inflammatory airway constriction.Methods According to the different treatment methods,63 patients with tuberculosis airway constriction were divided into two groupsthe balloon dilatation group (balloon group,34 cases) and high frequency endotherm knife combined with balloon dilatation group (combination group,29 cases).The patients in both groups accepted endoscopic therapy once a week.Effective rate of recanalization for the narrow airway,treatment frequency,the time spent in tuberculosis bacterium clearing,as well as intraoperative and postoperative complications were recorded.Results The rate of recanalization in baboon group and combination group were 52.9％ (18/34) and 79.3％ (23/29),and there was significant difference (x2 =4.79,P =0.03).The treatment frequency in balloon group and combination group were (3.5 ± 1.3) times and (1.5 ± 1.1) times,and there was significant difference (t =6.53,P ＜ 0.01).The time spent in tuberculosis bacterium clearing in balloon group and combination group were (22.3 ± 3.6) d and (12.3 ± 2.1) d,and there was significant difference (t =11.69,P ＜ 0.01).Conclusions Fiberoptic bronchoscope high frequency endotherm knife combined with balloon dilatation in treating tuberculosis inflammatory airway constriction is efficient and safe.It can reduce the frequency of interventional therapy,shorten the time spent in tuberculosis bacterium clearing,which is worthy of clinical application.
