There will be a scar at the site of the navel, which itself is a scar from the site of the umbilical cord that has healed. If the appearance is unattractive after 6 months or so, a plastic surgery evaluation would be my suggestion. Best wishes.

The umbilicus is just a scar and that is why it looks different in all of us. It can be reconstructed easily at a later time
If you need to have your belly button removed because of infection following a duodenal switch, then you should have it done. Post-operatively, this does not bother most people but I would recommend looking at pictures online to see if it will bother you.
