BACKGROUND: Posttraumatic empyema is relatively unusual. There are little data comparing the results of various interventions, and no data that have documented the restoration of lung volumes.
METHODS: We compared patients with posttraumatic empyema who were treated with catheter drainage or decortication. Computed tomographic scans of the chest were obtained before and after treatment, and computed tomographic modeling was used to determine the change in lung volumes after each intervention.
RESULTS: From 2006 to 2010 there were 478 patients admitted after sustaining chest trauma and 25 (5%) developed an empyema. The definitive treatment was decortication in 15 patients (60%) and chest tube or catheter drainage in 10 (40%). Four patients (16%) initially treated with chest tubes later required decortication. The overall complication rate was 33% for decortication and 100% for catheters. There was no significant difference in days of mechanical ventilation (catheter-median 0, SD±13 days; decortication-median 10, SD±12 days; p=0.6), total length of stay (catheter-median 15, SD±36 days; decortication-median 27, SD±17 days; p=0.9), and intensive care unit days (catheter-median 6, SD±19 days; decortication-median 15, SD±17 days; p=0.5). After chest tube drainage, the lung volume increased on average by 751 cubic centimeters (range, 99 to 1,982 cc). After decortication, the lung volume increased on average by 1,519 cc (range, 616 to 2,916, p=0.02).
CONCLUSIONS: Decortication for posttraumatic empyema results in higher postoperative lung volumes than catheter drainage and has a lower complication rate. Decortication is more effective in restoring full pulmonary capacity in the treatment of posttraumatic empyema.
