[Use of endobronchial valve in postresection empyema and residual cavities with bronchopleural fistulas].

The results of treatment are analyzed in 78 patients with brochopleural fistilas after lung surgery. A method for imaging the draining bronchus under endoscopic guidance, by using the foamed dye administered into the residual cavity, has been developed. A valvular bronchial blocker for abolishing the function of bronchopleural fistular inserted into the lobular and segmental bronchus at bronchoscopy was designed and clinically tested. This procedure allows resurgery to be avoided in 91.7% of cases.
