Thanks. Actually a friend on another forum was able to give me this link:

http://www.thepetcenter.com/sur/io.html

It tells you all about the surgery, pictures included, and even how to feed them afterwards. It was hard for me to look at and read but it helped me knowing what he might go through tomorrow and knowing now what to do when he gets home. For anyone going through this I would suggest they check out that link,
