[Intrathoracic Vacuum-Assisted Closure in the Treatment of Pleural Empyema and Lung Abscess].

BACKGROUND
Complex pleural empyema or lung abscesses are either characterised by long-standing treatment (including treatment failure) or by a bad general condition of the patient (multiple morbidity, sepsis). The operative rectification is often associated with increased morbidity and mortality rates in these cases. Traditionally, the therapeutic tendency for such patients was towards primary creation of a thoracic window including open wound treatment, but this was always also associated with a long sickness and restrictions in the quality of life. The intrathoracic vacuum treatment (VAC) offers here entirely new options in the treatment of complicated pleural empyema and lung abscesses.


METHOD
We present an illustration of our own clinical experience associated with a selective literature research via Medline (keywords: VAC, vacuum-assisted closure, thoracic empyema).


RESULTS
After the initial successes of the extrathoracic application of the VAC treatment, the procedure was also analysed for its intrathoracic/pleural use to treat pleural empyema and lung abscesses with and without bronchus stump insufficiency. Initially, the use of the intrathoracic VAC treatment was carried out via a thoracic window (with rib resection), later we developed a minimally invasive procedure (Mini-VAC) while relieving the osseous thorax. An additional intrapleural rinsing with antiseptics (Mini-VAC-Instill) is very practical in cases of proven germ populations. The benefits of the Mini-Vac/Mini-VAC-Instill are: immediate secretion suction with quick local cleaning, rapid germ eradication with a small risk of a fresh population, improvement of the expansion behaviour of the lung as well as short treatment times with quick reclosure of the thorax. In addition to many retrospective examinations, there has so far only been one cohort study in which the classic thoracic window was compared with the VAC treatment. The duration of the stomatic situation as well as the long-term survival in the VAC group were better here than those in the non-VAC group.


CONCLUSION
The intrathoracic VAC treatment (Mini-Vac/Mini-VAC-Instill) is an innovative procedure that promotes wound cleaning and wound healing in complicated pleural empyema and lung abscesses. Due to the benefits of this procedure, including the improvement of the patient's comfort and the quality of life, the procedure has seen a rapid and broad clinical acceptance.
