[Open window thoracostomy and muscle flap transposition for thoracic empyema].

Abstract

Open window thoracostomy for thoracic empyema: Open window thoracostomy is a simple, certain and final drainage procedure for thoracic empyema. It is most useful to drain purulent effusion from empyema space, especially for cases with broncho-pleural fistulas, and to clean up purulent necrotic debris on surface of empyema sac. For changing of packing gauzes in empyema space through a window once or twice every day after this procedure, thoracostomy will have to be made on the suitable position to empyema space. Usually skin incision will be layed along the costal bone just at the most expanded position of empyema. Following muscle splitting to thoracic wall, a costal bone just under the incision will be removed as 8-10 cm as long, and opened the empyema space through a costal bed. After the extension of empyema space will be preliminarily examined through a primary window by a finger or a long forceps, it will be decided costal bones must be removed how many (usually 2 or 3 totally) and how long (6-8 cm) to make a window up to 5 cm in diameter. Thickened empyema wall will be cut out just according to a window size, and finally skin edge and empyema wall will be sutured roughly along circular edge. Muscle flap transposition for empyema space: Pediclued muscle flap transposition is one of space-reducing operations for (chronic) empyema Usually this will be co-performed with other several procedures as curettages on empyema surface, closure of bronchopleural fistula and thoracoplasty. This is radically curable for primarily non fistulous empyema or secondarily empyema after open window thoracostomy done for fistula. Furthermore this is less invasive than other radical operations as like pleuro-pneumonectomy, decortication or air-plombage for empyema. There are 2 important points to do this technique. One is a volume of muscle flap and another is good blood flow in flap. The former suitable muscle volume is need to impact empyema space or to close fistula, and the latter over-elongation and bending of pedicles should be avoided. Actually, after removing several costal bones on the empyema space, empyema wall will be incised for about 2/3 of total empyema length along costal beds. Then muscle flap will be introduced into cleaned up space and sutured on empyema surface at several points. It is better to lay small vacuum drain tubes along flap within empyema space.
