33 year old male, 5'10 and 140kg. Have a large 6 month old incision scar that covers the length of my abdomen. Options? (photos)

I am a 33 year old male, 5'10 and 140kg. I have a large 6 month old incision scar that covers the length of my abdomen. The scar has left an asymmetrical indent below my belly button. I also had a stoma which was reversed last month leaving an inverted scar at the stoma site. Is it possible to fill in the indented scars to recover the previous shape of my body? Can the scars be removed? Do procedures exist that can fill in what appears to be missing areas of body fat?
