Pilonidal sinus disease (PSD) in children is associated with significant morbidity and recurrence risk. Multiple surgical techniques are used, including excision with open healing, primary midline closure, off-midline closure, flap reconstruction, and minimally invasive approaches. However, high-quality comparative data in pediatric populations are limited, and adult data cannot be directly extrapolated.
This single-center retrospective cohort study aims to compare the effectiveness of different surgical techniques used for curative treatment of PSD in children treated at CHU Angers between January 1, 2015 and March 31, 2025.
The primary endpoint is surgical failure at 2 months, defined as absence of complete wound healing or early recurrence. Secondary outcomes include postoperative complications, time to healing, pain outcomes, length of hospital stay, and recurrence at 1 year.
Results are expected to help optimize institutional management strategies and contribute to pediatric-specific evidence.
