About the study

Pilonidal disease is a chronic condition that causes painful inflammation and infection near the top of the buttocks. Many patients require surgery, and one commonly used approach is a bilateral gluteal fasciocutaneous flap with midline closure along with placement of an extracellular matrix to support wound healing. Although effective, this surgery can still lead to wound problems such as infection, fluid collection (seroma), wound separation (dehiscence), and delayed healing.

This study aims to compare two different solutions used to rinse the surgical wound before closing it. One solution is Irrisept, which contains 0.05% chlorhexidine gluconate, an antiseptic designed to reduce bacteria. The other is normal saline, which is the current standard rinse used in surgery. The goal is to determine whether using Irrisept can safely reduce post-operative infections and wound-related complications in patients undergoing flap closure and extracellular matrix implantation for pilonidal disease.
