Abstract
BACKGROUND
Wound healing after resection of large soft-tissue tumors is often impaired by large dead space and fluid collection. Recently, the authors were able to show an association of wound complications with worse oncologic outcome in soft-tissue sarcomas. The aim of the study was to examine the value of closed-incision negative pressure wound therapy on postoperative wound drainage and wound complications after soft-tissue tumor resection.
METHODS
Patients for whom resection is planned of a soft-tissue tumor larger than 10 cm in diameter of the extremities or the trunk were allocated randomly to one of two groups. After wound closure, patients in the study group received closed-incision negative-pressure wound therapy for a duration of 5 days, whereas those in the control group received regular dressings. The amount of drainage fluid, course of wound healing, length of hospital stay, and wound edge perfusion at postoperative day 5 measured by white-light infrared spectroscopy were compared.
RESULTS
Sixty patients could be included in the study with even distribution to both study arms, meeting the goal. The postoperative course of wound drainage volume was significantly lower in the study group, and hospital stay was significantly shorter, with 9.1 ± 3.8 days versus 13.9 ± 11.8 days. The occurrence of wound complications was significantly lower in the study group on time-to-event analysis (one versus six). Tissue spectroscopy revealed a significantly higher oxygen saturation increase in the wound edge for the study group versus the control group.
CONCLUSION
Closed-incision negative-pressure wound therapy should be considered for patients undergoing resection of large soft-tissue tumors.
