[Video-assisted thoracoscopic access in pleural empyema compared with mere chest tube drainage]

[Treatment of pleural empyema]

Pleural empyema remains a frequently encountered clinical problem and is responsible for significant morbidity and mortality worldwide. Its diagnosis may be difficult; delays in diagnosis and treatment may contribute to morbidity, complications, and mortality. The management of parapneumonic effusion and empyema depends on timely, stage-dependent therapy and the underlying etiology. Thoracentesis and antibiotics remain the cornerstones of treatment in stage I disease. In the early fibrinopurulent phase (stage II) thoracoscopic methods should be considered. As treatment strategy for this stage, fibrinopurulent pleural empyema entails thorough debridement of multiloculated collections from the pleural cavity by video-assisted thoracic surgery. After evacuation of multilocular effusions and the removal of fibrin deposits with drainage by two intercostal chest tubes, irrigation treatment helps to achieve clarity of the pleural discharge. Open thoracotomy and decortication are reserved for organized, multiloculated empyema with lung entrapment (stage III disease). Early drain removal may lead to rapid symptomatic recovery and complete resolution.

Computed tomography or ultrasonically guided pigtail catheter drainage in multiloculated pleural empyema: a recommended procedure?

OBJECTIVES

The role of image-guided pigtail catheter drainage in the treatment of pleural empyema is associated with different outcomes, dependent on the stage of the disease. No agreement concerning its use exists.

METHODOLOGY

Fourteen patients at a fibropurulent stage of pleural empyema initially treated with computed tomography (CT) or ultrasonically guided pigtail catheter drainage were reviewed. All patients were admitted with clinical symptoms of sepsis. Chest X-ray, CT scan and/or ultrasonography and thoracentesis with biochemical examination revealed multiloculated pleural empyema. Despite the diagnosis of multiloculated empyema, CT or ultrasonically guided pigtail catheter drainage was performed. However, septic symptoms deteriorated and all cases proceeded to thoracotomy with decortication.

RESULTS

Image-guided drainage failed in all patients. Septic symptoms disappeared within 24-48 h after decortication. The patients recovered without sequela, were discharged 6-15 days (mean: 9.2 days) postoperatively and were able to return to normal physical activity.

CONCLUSIONS

Computed tomography or ultrasonically guided pigtail catheter drainage can not be recommended in the case of a fibropurulent stage of empyema thoracis.
