Lipo 360 can be done in your abdomen and be successful. However, in your back, you will most likely have hanging skin. You may benefit from a butt lift or a back lift, depending on where most of the skin is coming from. In your case, it appears to be high so you may benefit from the back lift...
You have contour deformity from liposuction. This can be corrected by tracting it again with a liposuction cannula or adding fat to the area at the same time.
