[Role of flexible bronchoscopy in the treatment of infection-associated atelectasis in children].

OBJECTIVE

Infection-associated atelectasis is rather common during childhood and the effects of drug therapy are often unsatisfactory. The present study aimed to evaluate the effectiveness of flexible bronchoscopy in the treatment of infection-associated atelectasis in children.

METHODS

One hundred and twenty-five patients (68 male and 57 female; age ranged from 10 d to 14 years and their courses of disease were from 3 d to 2.5 years) with infection-associated atelectasis confirmed by chest X-ray or CT were enrolled in the study. The following conditions were excluded by bronchoscopy: airway foreign body, airway anomalies, tumor, tuberculosis. The patients were divided into two groups: flexible bronchoscopy group and medication group. In the flexible bronchoscopy group, 65 patients were treated mainly with flexible bronchoscopy whereas in medication 60 group patients only received medication. Chest X-ray or CT was regularly reviewed for every patient, meanwhile the effect of flexible bronchoscopy at different courses of disease was observed.

RESULTS

Flexible bronchoscopy group and medication group had no significant differences in age, sex and course of disease (P > 0.05). In flexible bronchoscopy group 39 patients were cured, 20 were improved and 6 cases had no change; in medication group 17 patients were cured, 25 were improved and 18 had no change. The two groups had significant differences (P < 0.01); in bronchoscopy group there were significant differences among patients with the courses of disease less than 3 months, 3 to 6 months and more than 6 months.

CONCLUSIONS

The authors concluded that flexible bronchoscopy was an effective method for treatment of infection-associated atelectasis. Flexible bronchoscopy can reach pathological part and clear pus and granulation. It can remove obstruction and relieve symptoms. When course of disease was short, bronchoscopic therapy was advantageous to recovery of atelectasis. Bronchial washing may overcome the shortcomings of bronchoalveolar lavage, therefore the former seemed to be more suitable for treatment of infection-associated atelectasis.
