Do I have a case to file with my doctor? My doctor fails to diagnose me with gallbladder problems now I had an emergency gallbladder removal.

In order to prove a medical malpractice case, a claimant must prove a failure to conform to accepted practice, resulting in an injury. A bad result is not enough, and if it is a "judgment call" by the doctor, there is no malpractice, even if the doctor made the wrong call. You will need to get copies of ALL of your medical records and have a surgeon review them; if he/she is willing to testify that your previous surgeon(s) failed to conform to accepted practice, then you have a case.

You have a case if another doctor opines that your doctor departed from the standard of care and that the surgery could have been avoided.
