Mike, I have had 2 of mine have the surgery and they both did very well. One was also diagnosed with other things found during surgery even and lived to be a tad over 7 and he was 5 when he had the surgery. He did have other issues thru out the 2 years after his surgery that had to be taken care of also. The other one has only had his surgery this Thanksgiving and is doing well. Hope this helps you. Hugs, Nancy [Posted in FML 5918]
