Agree! Please pay very close attention to the Procedure Consent

Form. If you signed your name on it, you've given consent to such conditions as:

• If other urgent procedures that were unanticipated, you consent to any additional procedures that is in your best interests;
• Recuperation is NOT guaranteed
• Risks being told and you understand them
• You understand the alternatives but you consent to take the surgery

And more!

In general, those medical records belong to you and you have a right to get a copy from the hospital. 

Your case is quite common for any Surgery Department. Things could go wrong in many ways, that's why we have to do reserach to find out a good surgeon in particular. If you went to a teaching hospital, more likely you were at hands of those fellows. 

Good luck!
