Background:
Over the last decades, novel therapeutic options have emerged for the surgical treatment of pilonidal sinus disease (PSD). The aim of this study was to evaluate the outcomes of trephine/pit excision surgery with or without laser therapy in patients with PSD.
Methods:
A retrospective cohort study was conducted at a large tertiary medical center, including all adult patients with PNS who underwent trephine surgery with/without laser therapy between 2016 and 2021[AUTHORS TO INSERT MONTH]. Propensity score matching was used to address confounding factors, and the primary outcome was the 1-year recurrence rate.
Results:
The study included 221 patients with PSD, with a mean age of 23.73 years (87.7% male). In the unmatched cohort (130 trephine surgery alone, 91 trephine surgery + laser therapy), significant differences were observed in mean age (23 vs. 25 years; p < 0.01)[AUTHROS TO USE MEDIAN PLUS RANGE OR ADD SD] and surgeons' experience (p = 0.014). Propensity score matching was applied to overcome confounding factors, resulting in a matched cohort including 73 patients in each group. The addition of laser therapy demonstrated a significantly lower recurrence rate (8.2% vs. 32.9%; p < 0.001) compared to pit excision without laser therapy. Logistic regression analysis showed that the addition of laser was significantly associated with a lower risk for recurrence (OR 0.23; 95% CI 0.089-0.633; p < 0.01).
Conclusion:
The incorporation of laser therapy along with trephine/pit excision surgery significantly reduces the recurrence rate in patients with PNS. Further prospective studies are needed to confirm our findings.
