Abstract:
Objective To explore the efficacy and safety of the bronchoscopic high frequency electrocoagulation combined with balloon dilatation in treating tuberculosis inflammatory airway constriction. Methods According to the different methods of treatment, 55 patients with tuberculosis airway constriction were randomly divided into two groups, the balloon dilatation group (26 cases) and combination group (29 cases). The patients in balloon dilatation group underwent bronchoscopic balloon dilatation and the patients in combination group underwent bronchoscopic balloon dilatation combined with high frequency electrocoagulation. The patients of the two groups accepted endoscopic therapy once a week. Effective rate of recanalization for the narrow airway, frequency of effective treatment and the time of tuberculosis bacterium vanishing was recorded. Intraoperative and postoperative complications were also observed. Three months after the treatment, all patients accepted bronchoscopic to observe and assess the airway restenosis rate. Results After treatment, the effective rate in balloon dilatation group and combination group had no significant difference[69.2%(18/26) vs. 89.7% (26/29 )](P＞ 0.05 ),but frequency of effective treatment and time of tuberculosis bacterium vanishing had significant difference[(3.5 ±1.3) times vs. (1.5 ± 1.1) times, (23.3 ±3.6) d vs.(13.2 ±2.3) d](P<0.01). There was no significant difference on the intraoperative and postoperative complications between two groups (P＞0.05). The airway restenosis rate was 33.3%(6/18) in balloon dilatation group and 7.7%(2/26) in combination group after treatment for 3 months (P ＜0.05). Conclusions Combination of bronchoscopic balloon dilatation and high frequency electrocoagulation is an efficacy and safety way for the tuberculosis inflammatory airway stenosis. It can reduce the frequency of interventional therapy, shorten the time of tuberculosis bacterium vanishing, and may also decrease the airway restenosis rate.
