Abstract

Background In patients with parapneumonic empyema, decortication is usually preferred to ensure functional lung re-expansion. However, there could be patients exhibiting incomplete postoperative lung expansion and inadequate drainage despite decortication. Therefore, we evaluated factors affecting postoperative lung expansion in patients undergoing decortication.

Methods A total of 221 patients with pyogenic empyema who underwent video-assisted thoracoscopic surgery (VATS) between January and October 2016 in our hospital were reviewed in terms of surgical success. The following factors were evaluated: age; the time between identification of a localized effusion and surgical referral; chest tube drainage durations; any underlying morbidity preoperative blood culture data; and the thickness of the visceral pleura.

Results Several factors that significantly prolonged the postoperative time to lung expansion were evident in patients with diabetes mellitus (DM) and bacteremia; postoperative chest tube drainage was significantly longer in those with DM (p = 0.009) and bacteremia (p = 0.01); and postoperative hospitalization time was significantly longer in patients with bacteremia (p = 0.01). The thickness of the visceral pleura was strongly correlated with postoperative chest tube drainage duration and postoperative hospitalization time (Pearson correlation coefficient, r = 0.245, p = 0.00).

Conclusions In patients with DM, bacteremia, or thickened pleura, the time to lung expansion after operation was longer. Therefore, stricter pre- and post-operative control of blood-sugar levels and adequate antibiotics are required to facilitate postoperative lung re-expansion. In patients with thickened pleurae, prolonged chest tube placement is unavoidable.
