What are some non-invasive procedures to fixed a botched liposuction procedure? (Photo)

I received liposuction a year ago and was left with a soft bulge near my belly button. My plastic surgeon offered a revision procedure to remove the leftover fat, but I do not want to go through surgery again. The recovery process was very difficult. It was a long and painful recovery and left scars, so I would like to avoid another surgery if possible.
