Office-Based Surgical Intervention for Hidradenitis Suppurativa (HS): A Focused Review for Dermatologists.

Easily accessible office-based procedures that require minimal resources may facilitate timely surgical management of hidradenitis suppurativa (HS). This review focuses on excision and unroofing as two surgical HS treatments that can be tailored to the outpatient setting. Fifty-five articles were included in our review, representing 3914 patients. The majority were retrospective studies (58%, n = 32), and the studies reported data both across patients and by number of treated lesions. Recurrence rates for unroofing (14.5%) were found to be half that of excision (30%) across patients (p = 0.015) and slightly lower across lesions [20% recurrence vs 26% for excision (p = 0.023)]. Complication rates at the lesion level were also significantly associated with procedure, with rates after excision more than double those after roofing (26% vs. 12%, p < 0.001). The complication rate after combined medical and surgical therapy did not differ between procedures. Studies also suggest that continuing medical therapy in the perioperative period may be associated with improved recurrence rates, although delayed wound healing with biologic therapy has been reported. The existing data are limited by low-quality uncontrolled studies with small sample sizes, variable reporting of outcomes, and lack of uniform definitions for recurrence and remission. Further systematic prospective studies are needed to better compare complication and recurrence rates across these procedures in HS, especially in the context of concomitant medical therapy.
