Hello, I would like to ask about one detail of the Suporn technique. First, some background. In his case, the neovaginal cavity is lined with a skin graft, that is, a piece of skin that does not have any connection to the rest of the body. It has to be pressed onto existing tissue, from which oxygen will diffuse into the graft and soon capillaries will grow from the host tissue into the graft. At that point, the graft has "taken". I hope I'm describing it correctly.
This is in contrast to PI, where the neovaginal cavity is lined by skin that still has vascular and perhaps neural connection to the body. I think it's called a pedicled skin flap.
My question is: what does the graft in Suporn's case grow onto? Is it then basicaly fixed within the body? (In PI, I'd guess the vagina is a bit mobile.) The tissues surrounding the vaginal cavity are the rectum, colon, bladder, many muscles, and connective tissue all around... so I guess the graft attaches to lots of them...?
It seems to me that having a fixed vagina (Suporn) and a mobile vagina (PI) would be quite different in practice, yet I haven't seen this difference mentioned anywhere...
