[Treatment of experimental broncho-pleural fistula with myoplasty].

Surgical experiment of closing broncho-pleural fistula by muscle flap from the chest wall was conducted on the sheep model. The procedure was completed in two stages. During the first thoracotomy the middle lobe of the right lung was removed. In the second stage the vascularised muscle flap of the latissimus dorsi was inserted in the pleural space and stitched onto the bronchi stump closing broncho-pleural fistula. Microscopic investigation of lung, bronchus and muscle tissue performed after each step of procedure showed the inflammatory process primarily and the regression of it after the second stage. Well vascularised muscle flap is the best tissue for repair of broncho-pleural fistula.
