Key Points

To compare long-term outcomes of sinus laser-assisted closure (SiLaC) in primary versus recurrent sacrococcygeal pilonidal sinus disease.
Retrospective cohort study design
Comparison of outcomes between primary and recurrent cases
Evaluated recurrence rates and treatment feasibility
Acceptable recurrence rates for primary sacrococcygeal pilonidal sinus disease (SPSD)
Poorest outcomes observed in recurrent SPSD
SiLaC is a feasible first-line treatment option for primary SPSD

Abstract

SiLaC demonstrated acceptable recurrence rates for primary SPSD comparable to other minimally invasive techniques at long-term follow-up, but significantly poorer outcomes in recurrent disease. Therefore, SiLaC may be considered a feasible first-line option for primary SPSD, while recurrent cases require careful patient selection and consideration of alternative treatments.
