Thoracoscopic Debridement of Empyema Thoracis

Abstract

The primary treatment of empyema thoracis remains intercostal tube drainage together with antibiotics. Failure of primary treatment has until recently been an indication for thoracotomy and decortication. Video-assisted thoracoscopic debridement (VATD) has increased the available treatment options but requires validation. A retrospective analysis was undertaken of 44 consecutive patients who presented for surgical treatment of empyema thoracis over a 3-year period. Two patients were unsuitable for VATD and were treated with open decortication (OD). Thirty patients were successfully treated by VATD. Two patients were converted to OD at the first operation, and 10 patients required OD as a second procedure. The mean duration of preoperative symptoms before referral was 37.6 +/- 11.8 days (VATD) and 40.1 +/- 11.6 days (OD) (p = not significant). The mean duration of hospitalization before transfer was 13.7 +/- 2.4 days (VATD) and 11.5 +/- 3.4 days (OD) (p = not significant). Intercostal drainage was required for 4.0 +/- 0.3 days (VATD) and 8.5 +/- 2.0 days (OD) (p = 0.004). The postoperative hospital stay was 5.3 +/- 0.4 days (VATD) and 10.3 +/- 2.1 days (OD) (p = 0.001). Primary surgical therapy with VATD should be considered for all patients with pleural empyema, irrespective of the duration of symptoms. This approach does not preclude OD as a secondary procedure or conversion to OD after initial thoracoscopic assessment. The major advantages of VATD over OD are a shorter duration of postoperative intercostal drainage and reduced postoperative hospitalization.
