[The endoscopic treatment of bronchial fistulas by submucosal injections]

A total of 21 patients (aged 30-72) with bronchial stump fistulas (307 mm) were treated by a newly developed method of treatment of purulent-destructive pulmonary diseases. This technique represents a gradual narrowing of the bronchial fistula lumen due to infiltrate formation in the submucosal bronchial layer. The volume formation substance biopolymer "DAM+", hydrogenous biopolymer with ions of silver "Argiform" for endoprosthesis of the soft tissues, is injected into the submucosal bronchial layer. It is necessary to make 5-20 fibrobronchoscopies for bronchial fistula healing. No complications occurred as a result of this treatment. The healing of bronchial fistula and bronchial stump epithelization were found in 18 patients.
