About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients aged 18 years or older;

Patients undergoing major lower extremity amputation, including below-knee amputation, through-knee amputation and above-knee amputation, for any indication;

Patients with primary closure of the surgical incision using either interrupted or continuous sutures

Disqualifiers

Patients <18 years;

Women who are pregnant and/or breast-feeding;

Patients with amputations performed without primary skin closure, including guillotine amputations, amputations deliberately left open for drainage purposes and amputations with soft tissues defects at the stump;

Patients with amputations where skin glue is the only means of skin closure

3

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)
