Negative Pressure Wound Therapy with Instillation and Dwell Time in the Surgical Management of Severe Hidradenitis Suppurativa

Background: Hidradenitis suppurativa (HS) is a physically debilitating disease that greatly impairs the quality of life of affected individuals. Advanced disease is often difficult to treat with topical and systemic therapies. Surgical resection of diseased skin has become paramount in HS management but proposes challenges of wound care and closure.

Methods: Four patients with a total of 12 complex wounds were treated over a three year period. All of the patients were males between the ages of 28 and 61 years. The lesions were located on the buttocks (n=5), chest (n=1), perianal (n=2), perineal (n=2), and axillary regions (n=2). A protocol of wide local excision, followed by negative pressure wound therapy with instillation and dwell time (NPWTi-d) to decrease bioburden and promote angiogenesis of the exposed base, and subsequent skin grafting was used. Patients remained hospitalized between procedures.

Results: The original wound area ranged from 210-540 cm. Skin grafts of comparable sizes were taken from donor sites. The average duration of NPWTi-d placement was 3.5 days and the average time from excision to wound coverage was 4.3 days. The percent of graft uptake ranged from 70%-90%. All patients were resolved of their local disease with no complications.

Conclusions: Surgical management of HS can be complicated by difficult closures. This case series demonstrates that wide local excision followed by NPWTi-d and skin grafting is able to achieve local resolution of disease in HS patients who have failed multiple minimally invasive therapies.
