[Analysis of postoperative thoracic empyema].

We experienced 15 cases of pyothorax after thoracotomy. Six were pyothorax without bronchial fistula and 9 were with fistula. All of former were cured by the closed drainage and/or open window thoracostomy. Two of pyothorax with fistula, who were treated with the tube drainage, died of respiratory insufficiency. Five cases who underwent the open window thoracostomy survived well. Omentopexy was performed in 2 of pyothorax with fistula and results were excellent.
