Question: How could surgeons remove the shrapnel from Tony's chest when they were unable to before?
Answer:Advances in technology. Throughout the film series, we've seen improvements being made to technology, so it's entirely reasonable, particularly with Stark turning his considerable intellect towards the medical field in order to remove the Extremis infestation from Pepper, that he could have determined a safe method of finally removing the shrapnel.
