Neovaginoplasty for radiation-induced vaginal stenosis using Nile Tilapia Fish Skin as a biological graft

Tilapia skin showed good results when used as a biological graft for surgical management of Mayer–Rokitansky–Küster–Hauser syndrome. Thus, our researchers considered the use of this biomaterial for neovaginoplasty in radiation-induced vaginal stenosis. We report the case of a 41-year-old female patient with a total occlusion of the vaginal canal after radiotherapy for vaginal cancer. McIndoe neovaginoplasty using tilapia skin as a scaffold for proliferation of new vaginal epithelium was performed. Initially, laparoscopic dissection of the rectovaginal septum and vesicovaginal space spaces was conducted. In the vaginal surgical time, a transverse transmural incision was made in the scarred vaginal reminiscent followed by blunt dissection and insertion of an acrylic mold covered with tilapia skin. Good anatomical and functional outcomes were noted. Vaginal reconstruction with tilapia skin seems to be an excellent option for patients with radiation-induced vaginal stenosis due to its wide availability, easy application and high effectiveness.
