I still haven't figured out exactly what the metal titanium clip you are talking about is for, is it a metal stent, for bile duct molding?
I used to be a doctor, now I work as an attorney, and have recently been working on a medical malpractice case after a bile duct ERCP, but still, it's not very clear why the titanium clips are placed and what they are used for?
In general, if a foreign body that should have been removed but was not is left behind, it is definitely medical malpractice, and as to whether there is any harm to the human body, that is a matter of calculating the amount of medical compensation, and a matter of determining whether or not it constitutes a disability.
For you, the main thing is to solidify the evidence, first copy and seal the medical records, and then, according to the evidence and then negotiation and litigation, for the amount of compensation, may depend on the results of the appraisal, and the hospital's fault and disability level.
And the hospital's signature is generally a surgical protocol, the protocol only has the role of informing, if there is fault, can not be exempted, so as long as the hospital is at fault, you can claim compensation.
