Pilonidal sinus disease (PSD) is an acquired condition involving chronic inflammation and infection in the sacrococcygeal region. Over time, PSD can lead to recurrent infections, draining tracts, abscess formation, and the need for repeated procedures. Surgical management often includes flap-based closure techniques. The bilateral gluteal fasciocutaneous flap with midline closure, combined with implantation of an extracellular matrix, is designed to provide durable coverage and improve wound healing. However, wound-related complications remain common. Reported rates of wound dehiscence for flap-based closures range from approximately 10% to 36%, and infection and seroma formation continue to be major concerns.
This prospective study evaluates whether the use of Irrisept (0.05% chlorhexidine gluconate) as an antimicrobial irrigation solution during flap closure can reduce these complications compared with standard irrigation using normal saline. The study will assess safety and effectiveness by comparing the rates of postoperative infection, seroma, hematoma, wound dehiscence, and time to complete wound healing between the two groups.
Participants will be adults undergoing bilateral gluteal fasciocutaneous flap closure with implantation of the Myriad extracellular matrix for treatment of pilonidal disease. All other aspects of surgical care will follow standard practice. Participants will be monitored after surgery for healing progress and any treatment-emergent adverse events.
