What this trial studies

This clinical trial investigates the use of 1470 nm intra-lesional diode laser treatment for patients suffering from hidradenitis suppurativa (HS) with two appropriate fistulas. The study aims to evaluate the effectiveness of this novel laser technique in promoting healing and alleviating symptoms associated with HS. Participants will receive laser treatment on both the right and left HS tunnels, with the goal of reducing pain and improving quality of life. The approach is based on emerging evidence suggesting that laser therapy may provide a less invasive alternative to traditional surgical interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years or older with two appropriate HS fistulas.

Not a fit: Patients with fistulas in areas that have previously undergone surgery or those with fragile health may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve healing rates and quality of life for patients with hidradenitis suppurativa.

How similar studies have performed: Previous studies on laser treatment for perianal fistulas have shown promising results, indicating potential success for this approach in HS.
