[Persistent pleural effusion following thoracic surgery].
BACKGROUND
Persistent postoperative pleural effusion can occur after thoracic surgery and might lead to progressive dyspnea with a subsequent complicated and prolonged hospital stay.


OBJECTIVE
The etiology, prevention and therapy of persistent pleural effusion after thoracic surgical interventions are presented.


METHODS
A selective literature search was carried out in Medline (pleural effusion, pleural empyema and chylothorax).


RESULTS
Persistent pleural effusions were observed especially after lung resection due to disorders in the pleural fluid balance and reduced postoperative lung expansion. An adequate chest tube management and postoperative physical therapy can reduce the incidence of postoperative pleural effusion. Relevant postoperative bleeding causes a hemothorax. An infection of the pleural effusion is defined as pleural empyema. These patients suffer from a significantly higher postoperative morbidity and require an adjusted multimodal treatment. Intraoperative injury of the thoracic duct can result in a postoperative chylothorax, which should be diagnosed early with specific laboratory investigations of the milky fluid. Interventional radiological procedures have now taken their place alongside conservative measures and surgical procedures in the therapy of chylothorax.


CONCLUSIONS
Persistent postoperative pleural effusion after thoracic surgical interventions warrant early diagnosis and an adjusted treatment in order to avoid further complications and to shorten the postoperative hospital stay.
