I'll leave the rest of your question to some-one with more knowledge than myself, but I can answer this part.
Anterior means you lie on your back for an operation. They cut you through your abdomen and they work from the front.
Posterior means the opposite. You lie on your stomach and they operate from the back.
Good luck if you decide to go through with the operation.
