[Abstract]

Objective: to verify the effectiveness of occluder in the control of pulmonary infection in the treatment of bronchopleural fistula;

Methods: the basic situation, treatment, chest imaging examination, antibiotic use, inflammatory index changes and other indexes of patients with bronchopleural fistula diagnosed in Guangdong Provincial People's Hospital from 2012 to 2022 were collected. The patients were divided into routine treatment group and occluder data group to evaluate the pulmonary imaging control, inflammatory index changes, hospital stay and cost.

Results: 22 cases of bronchopleural fistula were collected; In terms of treatment, 8 cases (36.4%) were treated with occluder, 11 cases (50%) were treated with conventional conservative treatment, and 3 cases (13.6%) were treated with other treatment methods such as biological glue, valve and operation. There were 18 cases (81.8%) of bronchopleural fistula complicated with infection, 16 cases (72.7%) of pneumothorax, 18 cases (81.8%) of pleural effusion, 7 cases (31.8%) of sputum culture, 8 cases (36.4%) of bronchial flushing fluid culture and 8 cases (36.4%) of pleural effusion culture. After inserting the occluder, chest imaging improved, pneumothorax absorbed and pleural effusion decreased, P < 0.05. The inflammatory indexes (WBC, PCT, CRP) were significantly higher than before, P＜0.05。 The length of stay was shorter than that of the routine treatment group, but the cost was higher than that of the routine treatment group.

Conclusion: the treatment of bronchopleural fistula with occluder is helpful to control pulmonary infection, pneumothorax absorption, improve inflammatory indexes, shorten hospital stay, but increase medical expenses.
