Total Vaginectomy instead of Colpectomy

Not sure if this is the right place to ask, but I haven't been able to find any information on vaginectomies that remove any and all vaginal tissue. Since there's three layers to the vagina in total, including the mucosa, I can't bring myself to be comfortable with leaving any tissue, whether there's a canal or not. A total vaginectomy seems to fit my criteria, but I've also seen it used to mean a colpectomy. So I was wondering if anyone here had experience having more than just the lining removed, or if there's a surgeon out there that'd consider it.
