title: [A case of a patient with post-operative empyema due to Mycobacterium chelonae].
abstract: We reported a case of a thoracic empyema due to M. chelonae (Atypical Mycobacterium, group IV) after thoracic surgery. A 49-year-old male underwent right middle lobectomy for pulmonary metastasis of esophageal cancer. Postoperative course was complicated for intractable air leakage, and several procedures were tried before successful re-thoractomy. Seven days after re-thoractomy, mycobacterium was proved in pleural effusion. And later on M. chelonae was identified by DNA hybridization method. Therefore, open window thoracotomy was performed at once. M. chelonae disappeared 7 days after operation and the patient discharged on 40 postoperative days. Thoracic empyema by M. chelonae is rare, and only one case was reported in Japan so far. Present case was not combined with infectious pulmonary disease by some mycobacterium. Therefore it is most reasonable to suppose this intrathoracic infection developed through the thoracic drain. In conclusion, because of the M. chelonae toleranced for almost all anti-biotics including anti-tuberculous agents, except clarithromycin, the timing of surgical approach is important for the treatment of this infectious disease.
