Post-operative wound issues in abdominal surgery have a significant impact on patient outcomes. This study is taking place to investigate if Negative Pressure Wound Therapy (NPWT) dressings reduces Surgical Site Infections, post surgical complications and improves scar appearance compared to standard dressings.
Many factors influence the risk of wound complications. Notably, the presence of unreconstructed proximal occlusive arterial disease is a major influence on stump healing. Patient factors such as smoking, diabetes, obesity, malnutrition and chronic kidney disease are non-modifiable, particularly in the short-term setting. However, surgical factors may be altered in an effort to reduce the risk of wound complications.
One option amenable to alteration is what dressing is applied to the closed incision upon procedure completion. The type of dressing may influence factors such as bacterial access to the wound, the development of collections of blood or fluid in the wound or fluid oozing from the wound. Collectively, these wound factors increase the risk of wound infection. Therefore, dressings which reduce these factors have the potential to reduce wound breakdown, thereby reducing the burden for patients and healthcare systems.
The investigators propose to conduct a multicentre randomised controlled trial comparing prophylactic single-use negative pressure wound therapy with standard dressings in patients with a closed incision following major lower extremity amputation in terms of SSI incidence, wound healing complications and scar appearance, patient quality of life and financial impact on the patient and healthcare system.

Health-related quality of life with the EuroQol-5 dimensions five level index questionnaire (EQ-5D-5L)
The questionnaire covers five dimensions of health: mobility, self-care, usual activities, pain or discomfort, and anxiety or depression. Each dimension has 5 levels: no problems (1), slight problems (2), moderate problems (3), severe problems (4) and extreme problems (5). The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. The raw scores are also converted to an EQ-5D index value using a scoring algorithm (British tariff) ranging from -0.594 (worst perceived health state) to 1.00 (best perceived health state)

Wound-QoL (Questionnaire on quality of life with chronic wounds)
Wound-QoL (Questionnaire on quality of life with chronic wounds) measures the disease-specific, health-related quality of life of patients with chronic wounds. It can be used in clinical and observational studies as well as in daily practice. The primary endpoint is the reduction of more than 0.4 points in the overall score of the Wound-Qol quality of life questionnaire between D0 and D14.
