Prior Abdominal Surgery Result MRSA and a Huge Seroma Needed Wound Vac Risk of Recurring with Tuck?

I had a multiple birth pregenancy resulting in a full abdominal incession that never heald correctly. First sinus track infection, led to surgery to clean, led to a sernoma MRSA+, and another surgery to place drains, still not healed after 3 months led to another surgery to place a wound vac with an opening the size of a football. Took 22 months from start of first surgery ,which was delivery of babies, to heal. I have lost 140 and would like to have panniculectomy what is risk of this again?
