Abstract
Introduction: Negative pressure wound therapy (NPWT) alone or with the addition of a split-thickness skin graft (STSG) are 2 reconstructive options available after surgical excision of axillary hidradenitis suppurativa (HS). The aim of this study was to retrospectively examine patients undergoing these treatments and to assess clinical and patient-related outcome measures. Methods: A single-centre, retrospective analysis was conducted, evaluating surgical excision of axillary HS, with STSG and NPWT, or NPWT alone. Data collected included No. of post-operative clinic visits, time to heal, size of wound, disease recurrence, follow-up time, Dermatology Life Quality Index (DLQI), the Generalised Anxiety Disorder Assessment (GAD-7), the Patient Health Questionnaire Depression Scale (PHQ-9), Pain Visual Analogue Scale (PAINVAS2), the Brief Illness Perception Questionnaire (BIPQ), and Dermatology Visual Analogue Scale (DERMVAS). Two-tailed t-test and Mann–Whitney Wilcoxon U-tests were used to assess for significant relationships. Results: One hundred five patients were included in the study, 44 who received NPWT alone, and 61 who received NPWT + STSG. There was no significant difference in follow-up time ( P = .934) or No. of follow-up appointments between groups ( P = .287). There was a significant difference in time to heal between groups, with STSG + NPWT observing a mean time of 2.77 months and NPWT alone observing a mean time of 4.40 months ( P = .0006). There was no difference in patient-reported outcomes between the 2 groups. Conclusion: There is no difference in patient-reported outcomes with the addition of an STSG to NPWT after surgical excision of HS. Wide excision and use of NPWT alone is an effective procedure for the treatment of axillary HS.
