Summary

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.

Detailed description

This is a single-center retrospective observational cohort study conducted in the Departments of Pediatric Surgery and Visceral Surgery at CHU Angers, France. All consecutive patients under 18 years of age who underwent surgical treatment for pilonidal sinus disease between January 1, 2015 and March 31, 2025 will be included. Surgical techniques analyzed include: * Wide excision with open healing * Wide excision with primary midline closure * Wide excision with primary midline closure and negative pressure wound therapy * Minimally invasive/endoscopic techniques The primary objective is to compare treatment effectiveness at 2 months postoperatively. Secondary objectives include comparison of complication rates, healing delay, postoperative pain, and recurrence at 1 year, as well as identification of predictive factors for recurrence. Data will be extracted from medical records and anonymized prior to statistical analysis.

Conditions

• Sacrococcygeal Pilonidal Sinus

Interventions

Type	Name	Description
PROCEDURE	Surgical treatment for pilonidal sinus disease, including various techniques including excision with or without primary closure, or endoscopic techniques.	curative treatment of pilonidal sinus, consisting in a wide excision followed by open healing or direct closure of the wound +/- negative pressure therapy dressing. Alterantivelly, an endoscopic procedure to destroy the pilonidal sinus can be performed.
