I agree that you will probably only need minimal help after your surgery however hopefully someone (your son perhaps) will need to check in on you to make sure you are managing any pain appropriately and if there are any other unexpected side effects. You probably won’t be able drive for at least a couple of weeks so transportation needs to be considered. Also, depending on the exact location of the incision(s) you may need some help with the wound dressings.

Good luck and have a good surgery and recovery!
