What can I do to get rid of the roundness in the stomach area and the wide waistline and stomach pouch? (Photo)

Thank you for sharing your question and photographs.  Unfortunately without an in-person examination it is difficult to offer definite advice as intervention will depend on the status of your abdominal wall after your rectus muscle was used for reconstruction.  If your abdominal wall has weakened it can stretch and create a bulge appearance.  If the integrity of your muscle fascia is intact your appearance may be the result of visceral fat - the fat around your internal organs which can only be treated with diet and exercise.  Hope this helps. 

I recommend a consultation with an expert in body contouring to determine what would be best for you. We do hi definition liposuction at the same time as tummy tuck and get amazing results. There are also non-invasive options that can help tighten and tone the area, if you're not a candidate.  I suggest you see an expert.  Best, Dr. Emer.

That what the doctor was telling you is that the "fat" you're bothered by is intraabdominal meaning that its wrapping your organs and isn't accessible by liposuction. This fat will go with diet and exercise but isn't something treated with liposuction or cosmetic procedures. Good luck.
