What kind of material/sutures etc is used to close a TT surgery?

I'm allergic to a lot metals and I'm wondering how the incisions for a full TT are closed? Even the staples the surgeon used for my small incisions on my stomach from my appendectomy were rejected by my body and left the incisions seeping until my doctor removed them. Most of the normal sutures I've had were tolerated from other past surgeries and injuries, but I'm worried I won't be able to get a TT done if staples or any metal is used to close them so I thought I'd inquire.
