Multiple liposuction on fibrous back fat. Are there bodies that can't have fat removed even though doctor is skilled?

Hi, I have done so many lipo on my upper back with different doctor and none of them ever remove my back fat. Some told me there is scar tissue or it's fibrous fat. I also tried 3 times cool sculpting to each area but not really having result.( see small result but it takes more time and money to remove them) .I saw dr su who dose very good lipo. I'm thinking to do it with him.I look so chubby because of those back fat
