Predictors of Successful Closure of Open Window Thoracostomy for Postpneumonectomy Empyema

Late onset of PPE and immediate OWT creation are significant predictors of OWT closure. Smaller dimensions of the pleural cavity appeared to increase the likelihood of closure. When the pleural cavity shows healthy granulation tissue and no bronchopleural fistula, the Clagett's procedure is safe and effective to obliterate the pleural cavity. Obliteration by muscle flap transposition can be reserved for patients with persistent or recurrent bronchopleural fistula.
