Endorectal Advancement Flap with Cook Biodesign Fistula Plug

This procedure involves covering the internal opening of a fistula using an endorectal advancement flap combined with a biodesign fistula plug to facilitate closure and healing. The Cook Biodesign plug, made from biologic material, acts as a scaffold for tissue regeneration. This approach is often used for complex or recurrent fistulas where standard treatments have failed.
