Preventing Pilonidal Sinus Recurrence With Laser Hair Epilation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Pilonidal sinus disease (PSD) is a common condition associated with significant morbidity and healthcare costs. High recurrence rates still pose a considerable challenge in managing PSD, with no universally accepted guideline in place to guide management. Laser hair epilation offers a way to reduce recurrence rates with reports within the current literature demonstrating positive outcomes compared to alternative approaches. This review was conducted by the Preferred Reporting Items for Systematic Reviews and MetaAnalysis (PRISMA) statement standards. The primary outcome measure was the recurrence rate of PSD at a minimum of one year following laser hair epilation. The electronic databases of MEDLINE, EMBASE, CINAHL, Google Scholar, PubMed, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched. OpenMeta Analyst (Brown University School of Public Health, Providence, RI) software was used for data synthesis. Three randomized controlled trials met the inclusion criteria with laser hair epilation treatments offering a significant reduction in PSD recurrence rates on odds ratio analysis: 0.319 ( 0.160, 0.636), P -value = 0.0001. Secondary outcomes involving patient disability days, caregiver disability days, health -related quality -of -life (HRQOL) scores, healthcare satisfaction scores, and perceived stigma were discussed qualitatively. The authors offer a decisive recommendation in favor of laser hair epilation in PSD; however, they recommend further high -quality trials to investigate the ideal timing and frequency of laser hair epilation sessions.
