SiLaT: A paradigm shift in the treatment of pilonidal disease?

Background

Pilonidal disease (PD) is a common condition for which the global incidence is increasing. Surgery is the currently preferred approach to treatment but there is a growing interest in new minimally invasive techniques, such as sinus laser therapy (SiLaT).

Aim

Our primary objective was to assess the efficacy of SiLaT for the treatment of pilonidal disease. The secondary objectives were to evaluate morbidity and patient satisfaction and identify predictive factors of success.

Methods

All adult patients, who underwent SiLaT in our department for a primary or recurrent pilonidal sinus from June 1, 2018, to December 31, 2020, were included in the study. Healing was defined as the closure of cutaneous orifices and the absence of seepage or abscesses.

Results

In total, 111 consecutive patients, for whom the male/female sex ratio was 2.1 and the mean age 28.8 (± 9.4) years, were included in this study. Eighteen (16.2%) patients had already undergone prior surgery for PD. The mean follow-up was 339.2 (± 221.4) days. A healing rate of 78.4% was observed, with a median time to healing of 20.0 days (15.0–30.0). The median time to return to usual activities was three days (1–7). The only postoperative complication was bleeding, which occurred for two patients (1.8%). Eighty-two patients (88.2%) reported being “very satisfied” with the treatment. Multivariate analysis showed no predictive factors for healing among the studied variables.

Conclusion

SiLaT is an efficient and safe procedure for the treatment of PD, with a high level of patient satisfaction. It will now be necessary to position it within the therapeutic algorithm.
