BACKGROUND: The possible connection between hidradenitis suppurativa (HS) patients undergoing surgery and higher complications/recurrences has been implied, but inconsistent results reported.
OBJECTIVE: To assess the complication and recurrence rates for HS patients undergoing surgery and to evaluate whether known HS comorbidities and habits (smoking, obesity and diabetes) have an effect on the complication and recurrence rates.
MATERIALS AND METHODS: A systematic review was conducted by 2 reviewers. PubMed and Embase were searched using a predefined search string created in collaboration between the authors and a librarian on January 23, 2019.
RESULTS: Of the 271 references in the original search, 54 relevant articles were identified. This systematic review indicates an overall mean complication rate of 24% and a mean recurrence rate of 20.1% for HS patients undergoing surgery.
CONCLUSION: No significant association between the known surgical risk factors and surgical complications-or recurrence rates in this patient group was found. This review revealed a lack of quality and quantity data in studying the complications/recurrences. The heterogeneity of the studies created limitations, and the presented mean complication/recurrence rates should be interpreted with the consequences thereof. It elucidates the need for better studies and a necessity for a standardized definition of postsurgical HS recurrence.
