This study aimed to characterize the surgical recurrences in patients with hidradenitis suppurativa (HS) treated with wide excision and second-intention healing. It was found that the severity of Hurley stage II at the surgical site, obesity, and higher IHS4 scores after surgery and at week 68 increased the risk of recurrence. Tunnel recurrence originated in the depth of the surgical scar, while AN recurrence originated in the borders of the surgical scar and may benefit from preoperative ultrasound.
Background: Surgery is an essential part of hidradenitis suppurativa (HS) treatment. Understanding and reducing surgical recurrence are crucial to obtaining the best results in patients' treatment. Objective: The aim of the study was to characterize surgical recurrences in a cohort of patients with HS treated with wide excision and second-intention healing. Methods: A prospective nested case-control study was conducted. A cohort of patients with HS treated with wide excision and second-intention healing was monitored for 68 weeks. The surgical procedure was classified as case (recurrence) or control (no recurrence). The type of recurrence was classified according to the elementary lesion in tunnel or abscess and inflammatory nodule (AN) recurrence. Sociodemographic and clinical data likely related to recurrence and the type of recurrence were evaluated. Results: Sixty-three patients were included, receiving a total of 82 surgical procedures. The mean age of the patients was 36.18 years, and the surgical site presented a Hurley stage II severity in 79.26% (65/82) of the interventions. Tunnel recurrence was observed in 8.5% (7/82) and AN recurrence in 15.85% (13/82) of the interventions. Obesity was associated with a higher risk of recurrence, for both tunnel and AN recurrence. Hurley III at the surgical site, a history of pilonidal sinus, and higher International Hidradenitis Suppurativa Severity Score System (IHS4) after surgery and at week 68 increased the risk of tunnel recurrence. Conclusion: We propose classifying surgical recurrence based on the elemental type of lesion. Tunnel recurrence could originate in the depth of the surgical scar and could be associated with both surgical site factors and inflammatory load. AN recurrence could originate in the borders of the surgical scar and may particularly benefit from preoperative ultrasound.
