I am very sorry; I have only seen it now!
BIG HUGS!
Please don't beat yourself up too much; you haven't failed him! You did the best for him and gave him a chance. Any operation comes with a risk; you didn't decide on it lightly and you did so with his best interests in mind. The rest is sadly out of your control.
I have over the years lost several guinea pigs in ops, so I know what bitter esperience it is and how big the feelings of guilt are afterwards; more than in other cases. You also can't really brace for it as you have to stay positive throughout the op and keep your fears under wrap for the sake of your piggy; seeing them confirmed is tough. Generally, operating on guinea pigs has become a lot safer, but it doesn't help you one bit if you end up on the wrong end.
The next operation is going to take a VERY deep breath and a leap of faith before you can commit.
