What is the best way to fix a seroma and possibly a pseudobursa above the belly button? (Photo)

I had an abdominoplasty 8 months ago. MRI shows small hernia over belly button and small seroma above belly button. Dr did not mention it showed significant pseudobursa. Does this mean it's not a Pseudobursa? I got a second opinion from another Dr and he wants to cut another incision (another scar?!) above belly button to do liposuction and remove the seroma. I'm very confused as to what is the best course of action. Stomach is very tender, swollen with shooting pains above the belly button.
