What happens to the staples inside my abdomen?

Scar over: I understand that you had abdominal surgery where metal clips were used inside your abdomen. Those are not dissolvable and will remain there. Granulation (scar) tissue will develop over those areas to wall them off from the surrounding environment, but they should be ok, otherwise.

Inert metal remains: Any staples intended to be left in place on intestine or blood vessels (for example) are made of inert metal that is well tolerated by the body. Over time a minor amount of scar tissue may cover them. Staples used to close an incision are different because they are intended to be removed after the incision heals.

Infection caused tumor: Immunosuppression lowers your immune defenses. One specific infection - the epstein barr virus can be a problem because it can stimulate 1 type of white blood cells, the b lymphocytes to grow uncontrollably. If this happens, treatment may include lowering (or stopping) immunosuppression, anti-viral medication and even chemotherapy.

Graft = Transplant: When we talk about transplant, the material that is transplanted is the graft. In your case, the bone is the graft. The type of transplant is a bone transplant. The other question is whether bone is being moved from somewhere else in your own body (an auto transplant), or from a deceased donor's body (an allo transplant).
