Wound closure techniques after wide excision for hidradenitis suppurativa: a systematic review and meta-analysis.

Abstract

Hidradenitis suppurativa (HS) is a chronic inflammatory disease that affects intertriginous skin areas, clinically characterized by recurrent inflamed nodules, abscesses, sinus tracts, and severe scars. Systemic treatments may provide temporary relief, while wide surgical excision offers prolonged disease-free periods. We evaluated the most efficient wound closure methods following wide excision of HS lesions in terms of recurrence, functionality, and quality of life. A systematic literature search was conducted in PubMed, Embase, Cochrane, and ClinicalTrials.gov, adhering to the PRISMA 2020 criteria. We included original studies published until February 2024, focusing on wound closure methods post-wide excision for HS. Data from 121 papers were analyzed using network and direct meta-analysis methods to compare recurrence and postoperative complication rates. From 1181 articles, 121 were included in the meta-analysis after removing duplicates and excluding publications that did not meet the inclusion criteria. Recurrence rates were associated with the type of reconstruction technique as follows: primary closure, 25% (95% confidence interval [CI], 20-30%); skin grafts, 18% (95% CI, 14-22%), and flaps, 12% (95% CI, 9-15%). Secondary intention healing showed a recurrence rate of 28% (95% CI, 23-33%). Flaps were associated with the lowest recurrence rates compared to other surgery techniques.
