This study is a single-center retrospective cohort study to compare a
novel minimally invasive surgical approach with EPC procedure in
patients with pilonidal sinus disease (PSD). The study was conducted in
accordance with the Declaration of Helsinki and in line with the
Strengthening the Reporting of Cohort Studies in Surgery (STROCSS)
criteria [26]. After the ethical approval was

There were two cohort groups in which the patients with PSD underwent
two different surgeries. One of the surgical procedures is SPC as a
minimally invasive surgical procedure, and the other one is EPC.
