NCT04325607

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.

Outcome Measures

Primary Outcomes (2)

  • The mean days to wound coverage with split skin graft (SSG) after excision of HS

    Mean days to wound coverage with split skin graft (SSG) after excision of HS in each treatment arm

    2 weeks

  • The difference in bacterial count on the wound after NPWTi against NPWT

    Reduction in the number of colony-forming unit (CFU) at each dressing change analysed using tissue culture of wound bed biopsies

    2 weeks

Secondary Outcomes (5)

  • Proportion of wounds covered with SSG at 1 week post excision

    1 week

  • Percentage of graft take at week 1 and week 4

    4 weeks

  • Number of patients with recurrence of HS at 3 and 6 months

    6 months

  • Number of patients with improved Dermatology Life Quality Index (DLQI)

    6 months

  • The difference in cost between both treatments

    6 months

Study Arms (2)

Negative Pressure Wound Therapy with instillation

EXPERIMENTAL

Patients in the treatment group will be initiated on VeraFlo instillation (NPWTi) therapy upon excision of HS

Procedure: Excision of HS followed by NPWTi

Negative Pressure Wound Therapy

ACTIVE COMPARATOR

Patient in the control group will be initiated on VAC therapy (NPWT) upon excision of HS

Procedure: Excision of HS followed by NPWT
