Brief Summary:


The current surgical management for severe Hidradenitis suppurativa (HS) involves wide excision of affected skin, resulting in a large soft tissue defect. The soft tissue defect will then be managed with Negative Pressure Wound Therapy (NPWT) to promote healthy granulation tissue formation for wound coverage with Split skin graft (SSG). This long interval between excision and reconstruction could result in long in-patient stay, increased risk of hospital acquired infection and reduced patients' quality of life.


The investigators wish to evaluate the use of Negative Pressure Wound Therapy with instillation (NPWTi), which has potential to allow early wound coverage with SSG, as an alternative to the current standard of care. The investigators hypothesise that NPWTi reduces bacterial load on the wound and allows early wound coverage hence improves patient satisfaction and reduces cost and length of hospital stay. The investigators plan to study up to 44 patients in total.
