Thoracoscopic management of postpneumonectomy empyema.

BACKGROUND: Even when there is no associated bronchopleural fistula, empyema is a serious complication of pneumonectomy. Aggressive surgical treatments are usually applied. However, a minimally invasive approach might achieve satisfactory results in selected patients.

METHODS: Out of 17 patients presenting with a postpneumonectomy empyema (PPE), 11 had a thoracoscopic approach. There were 9 males and 2 females, (age, 38-74; mean, 59 years). Ten patients had no proven bronchopleural fistula (BPF). One of them had a minor (< 3 mm) BPF. Empyema was confirmed by thoracentesis and bacteriological examination. All patients had immediate chest tube drainage and underwent emergency thoracoscopic debridement of the empyema. No irrigation was used postoperatively.

RESULTS: There was no mortality and no morbidity related to the procedure. The average duration of thoracoscopic debridement was 62 minutes (range: 45-80 minutes). In 8 patients the chest tube was removed between the fifth and thirteenth postoperative day (average, 8.6 days). They were discharged between the 9th and 24th postoperative day. In 3 patients, clinical and/or biological signs of infection persisted and reoperation was decided at day 5, day 10, and day 11. All 3 patients underwent open-window thoracostomy. The average follow-up of the 8 patients who underwent only thoracoscopy was 10 months (range, 2-27 months). None had recurrent empyema. The patient who presented with a minor BPF remained asymptomatic and is doing well after a 27 month follow-up.

CONCLUSIONS: Thoracoscopy might be a valuable approach for patients presenting with PPE with or without minor bronchopleural fistula.
