[Limited evidence for negative pressure wound treatment of skin transplants and closed surgical wounds].

The indications for negative pressure wound treatment (NPWT) are increasing, e.g. for fixation of skin transplant and primary closed surgical wounds. The evidence for indications and positive effects are limited. NPWT should exclusively be used for fixation of split thickness skin transplants when immobilisation is otherwise difficult and for primary closed surgical wounds in selected patients at risk. Future high-quality investigations are necessary to pinpoint indications for topical negative pressure therapy, the effect of the different NPWT-modalities, and the overall economy compared to conventional bandages.
