Thoracoscopic decortication: a role for video-assisted surgery in chronic postpneumonic pleural empyema.
BACKGROUND: We evaluated a technique of video-assisted thoracoscopic (VAT) decortication of the visceral cortex to reexpand entrapped lung in cases of chronic postpneumonic pleural empyema. METHODS: A prospective cohort study of 48 consecutive patients with multiloculated postpneumonic pleural empyema in whom visceral pleural decortication was required was studied. The effect of VAT decortication on perioperative outcome and factors affecting its success were assessed. RESULTS: Before the introduction of VAT decortication 12 patients were treated by thoracotomy (group T). In the subsequent 36 patients VAT decortication was attempted with success in 21 (group VS) but lung expansion was not observed in 15 patients (group VF) who required thoracotomy. There was no difference in the age or sex distribution of the 3 groups. Operating time was significantly longer in group T than group VS, mean difference 30.3 minutes (p = 0.001) and postoperative hospital stay was longer in group T than group VS, mean difference 2.9 days (p = 0.004). The success of VAT decortication was not related to either the delay between onset of symptoms or hospital admission and surgery; indeed the operating time decreased with increasing preoperative delay. However, success was related to increasing operative experience (p = 0.001). CONCLUSIONS: VAT decortication is a feasible new technique to achieve lung reexpansion in chronic postpneumonic pleural empyema and has perioperative benefits over thoracotomy.

Delayed referral reduces the success of video-assisted thoracoscopic debridement for post-pneumonic empyema.
The aim of this study was to evaluate the effect of preoperative delay on the efficacy of video-assisted thoracoscopic surgery (VATS) for post-pneumonic pleural empyema (PPE). This was a prospective study of 39 consecutive patients with PPE who were treated by VATS with curative intent over a 4-year period. Failure to obtain full lung re-expansion resulted in conversion to thoracotomy. Pre- and post-operative variables were correlated with surgical outcome. VATS debridement was successful in 16 (41%) patients while conversion to open decortication was needed in 23 patients (21 immediate, two delayed), There was no difference in the age/sex distribution of the two groups. In the failed VATS group the delay from hospital admission to operation was longer: 24 (2.1) vs. 16.6 (2.7) days (P = 0.03, 95% CI 0.53-14.3 days); operating time was longer: 128.2 (7.9) vs. 86.2 (10.4) min (P = 0.003, 95% CI 15.2-68.5 min) and post-operative stay was longer: 8.4 (0.8) vs. 5.2 (0.6) days (P = 0.03, 95% CI 1.1-5.3 days). VATS can be used successfully to treat PPE with a faster post-operative recovery when successful than open surgery. Delayed surgical intervention decreases the success of VATS thus earlier referral for surgical intervention in PPE (ideally within 21 days) is advocated to gain its full benefits.
