OBJECTIVE:
The study objective was to evaluate the clinical outcomes of surgical decortication as the first line of treatment for pleural empyema.
METHODS:
We analyzed the medical records of 111 patients who presented with empyema and were treated with simple drainage or surgical decortication as the first line of treatment at Gangnam Severance Hospital, a tertiary referral medical center in Seoul, Korea.
RESULTS:
Of 111 patients with empyema, 27 underwent surgical decortication as the first intervention. Surgical decortication showed a better treatment success rate in all study subjects (96.3%, 26/27 patients) compared with simple drainage (58.3%, 49/84 patients; P < .0001 for method comparison). After propensity-scored matching, decortication resulted in a better outcome (95.0%, 19/20 patients) versus drainage (56.7%, 17/30 patients; P = .003). Surgical decortication as the first line of treatment for empyema was the best predictor of treatment success after adjustment for compounding factors (odds ratio, 14.529; 95% confidence interval, 1.715-123.074; P = .014).
CONCLUSIONS:
The first treatment choice for pleural empyema is a critical determinant of ultimate therapeutic success. After adjusting for confounding variables, surgical decortication is the optimal first treatment choice for advanced empyema.
