Factors Affecting Wound Healing after the Wide Surgical Excision of Hidradenitis Suppurativa Lesions.

Background

Hidradenitis suppurativa (HS) is a chronic and inflammatory disease. Its management depends on the stage and extent of the disease. Surgery plays an important role in treatment options. This study explores the factors influencing healing after wide excision.

Methods

This study analyzed data from patients who underwent wide excision for HS between 2016 and 2021.

Results

A total of 160 patients (64.4% women) were included, with surgeries performed in the axillae (70), inguinal-ano-genital (73), and other locations (17, including gluteal). The mean TTWC was 74 ± 6 days, varying from 11 to 445 days. Factors negatively influencing TTWC included axillary localization (p < 0.001) and the presence of another inflammatory disease (p = 0.017). Factors positively influencing healing were smoking (<0.001) and previous or ongoing medical treatment (antibiotherapy or biologics) (p = 0.011). Obesity or being overweight did not impact the TTWC in multivariate analysis, although overweight was significant in univariate analysis.

Conclusions

While smoking cessation remains important in the management of HS, it does not appear to be a prerequisite for successful surgical treatment. Conversely, patients with an inflammatory disease or those undergoing surgery for an axillary lesion exhibit slower healing and should be informed of potential healing delays before surgery.
