What if a doctor left a piece of plasytic in your stomach after surgery?T

This certainly sounds like negligence, but the real question is how is it harming you.  Unless there is some injury, you are probably not going to get much even if you sued the doctor. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation.
