Presurgical Mapping With Ultra-high Frequency Ultrasound of Hidradenitis Suppurativa Lesions Treated With Wide Local Excision and Secondary Intention Healing.

BACKGROUND

Hidradenitis suppurativa (HS) is a challenging chronic inflammatory condition often requiring surgical intervention, such as wide local excision. Preoperative mapping with ultra-high frequency ultrasound (UHFUS) enables detailed assessment of lesion extension, particularly identifying tunnels and fistulas, facilitating surgical planning.

OBJECTIVE

This study aimed to analyze recurrence rates of HS lesions previously mapped with UHFUS and treated with wide excision and secondary intention healing.

MATERIALS AND

METHODS

A retrospective single-center study enrolled 40 patients with HS undergoing wide excision surgery after UHFUS mapping. Patients were assessed weekly until complete healing and then every 3 months, evaluating clinical and sonographic signs of relapse and pain using the visual analogue scale.

RESULTS

Results showed a population predominantly composed of women (65%) with a mean age of 39 years and a medium HS-Hurley score of 2.5. Over a 22-month follow-up, only 10% experienced clinical relapse, achieving an 90% total remission rate. Pain scores decreased significantly from Week 0 to Week 4.

CONCLUSION

The study highlights the clinical challenge of HS management, particularly regarding surgical planning and lesion margin definition. The remission rate observed in this study suggests the effectiveness of UHFUS-guided surgical approaches. Future studies should extend observation periods to further validate these findings.
