I would be very interested in hearing about this case since its been more than 6 months since the last comment was posted. My wife is experiencing many of the same things as your grandfather. Please let us know how things are going. I see what this kind of thing does to a person, I feel for your grandfather and for those that love him and don't know how to help him. It is a terrible thing for everyone involved.
What happened is that the dr. didn't do a ct scan so when he went in he was using 6 month old information so something happened. When the surgerywas over he said he had to make a judgement call and cut into him and ended up taking 60% of his colon
I am not a doctor, but I am smart enough to suspect this doctor messed up and needs to be sued. Get to another doc asap that has knowledge and can save your dads life. This is serious and his doctor in my opinion is incompetent.
You should find a new dr and lawyer asap!! That is horrible. What happened how did he slip and cut him open. What did he cut accidently?
