Stapler Staple

Sunday Morning we turn our back for 2 seconds and he got into our desk drawer and put some household staples in his mouth, he immeadtly threw up one of them, but I could tell he was havin a hard time swallowing whatever was left. We took him to the Hospital and they did an x-ray and said "Yes there is ONE in there and he should pass it within 72 hrs" well, we got a copy of the x-ray and it looks lke more than one staple. It looks like it is 4-5 of them stuck together in a row, like how they come, I could see how they ER thought it to be just one, but it is too big to be just one, they are only the little household stapler staples and the one in the x-ray looks to long to be just one. To me that seems like more to pass and more that could damage is intestines...I called the doc, but no one has called back yet...should I take him back to the ER or wait for the doc to call, or just let it pass...HELP!!!
