Diastasis recti after abdominal surgery- ware are my options that could improve the diastasis and bulging? (Photos)

You will need an in-person examination. There are likely options ranging from simply a rectus plication alone to one-sided muscle separation technique and even either along with "mesh" or similar product.I did a similar case three weeks ago with a large recurrent hernia 9 months after a robotic umbilical hernia repair with mesh. It only required closure of the hernia with an overlying secure rectus plication.

if there is diastasis or a hernia that developed, you can have it repaired.  You may benefit from having a plastic surgeon and general surgeon work together in light of your ileosotomy and previous surgery.  Timing is important to discuss; since you just had surgery I would avoid going under anesthesia for a while till you are fully recovered.    Also have the surgeon review the xray report with the radiologist to be sure it is a diastasis and not an incisional hernia from your surgery.  Good luck!
