Repairing diastasis recti without a tummy tuck? (Photos)

Yes absolutely. You are on the right track. It is very early in its stages but our outcomes have been excellent. 

It's called laparoscopic or robotic-assisted laparoscopic diastasis closure. It involves 3 5-8mm scars on your left side. The muscles are tightened from behind. 

This is done by those of us who perform laparoscopic or robotic surgery and hernia repairs. We are general surgeons typically. 

It is technically possible to repair the muscle below the navel but you would still need a cut to allow access which could be up to the same as a C Section. Then you might as well consider a 'mini' tummy tuck.

It is also technically possible let but a little more difficult to repair the muscle all the way to the top at the rib cage by endoscopic keyhole techniques and the 'floating umbilicus' approach where the stalk to the navel is cut to allow access and then re stuck down. The hernia could also be repaired at the same time but would add a further degree of complexity.

I hope that is helpful. 

Best wishes for your search to restore tour abdominal wall integrity!
