Can intrapleural alteplase treatment be an alternative to videothoracoscopic deloculation and decortication in pleural empyema?

Introduction
Chest tube drainage is the first step in the management of complicated pleural effusions that have turned into empyema. In cases where adequate drainage cannot be provided or deloculation is required, intrapleural fibrinolytic therapy or surgical deloculation can be performed. Alteplase is a suitable agent for intrapleural fibrinolytic therapy. On the other hand, video-assisted surgery is an effective and minimally invasive treatment option for lung re-expansion. Aim: The effect of intrapleural alteplase irrigation applied through the thoracic tube in the treatment of pleural empyema was investigated and whether it could be an alternative technique to video-assisted thoracoscopic surgery was evaluated.

Material and methods
The results of patients who were treated for empyema in our clinic were evaluated retrospectively. Twenty-one patients who underwent tube thoracostomy + intrapleural alteplase and 28 patients who underwent VATS deloculation were included in the study.

Results
The study included 35 male and 14 female patients. There were 21 patients in group 1, and 28 patients in group 2. The mean age was 50.6. The average length of thoracic tube stay was determined as 7.1 and 6.96 days. The duration of hospital stay in this group was 6.73 and 6.35 days. In 17 (81%) patients in group 1, the treatment was discontinued without the need for surgery.

Conclusions
VATS-D is an effective option in the treatment of pleural empyema. However, as seen in our study, intrapleural alteplase application is at least as effective as VATS-D in terms of treatment success.
