Belly button necrosis? (Photo)

Thank you for your pictures and questions. Without an in-person exam, it is impossible to tell you what is going on. It appears that there are some concerns with the blood supply to your umbilicus. This can sometimes result in complete or partial loss of the umbilicus, but the real fact is there is nothing you can do about it at this point other than treat the area with local wound care and give it time to declare whether or not it is going to make it. Follow closely with your surgeon and follow his or her instructions.Best of luck!

is possible but unable to say with certainty if you have this.  At this point, there isn't anything you can do about it so its best to focus on healing and cleaning the wound as best you can.  Work at getting those scabs along the incision cleaned up and you could use a 50:50 mixture of hydrogen peroxide and water and keep ointment on it.  You should be able to get it wet but you should be following the instructions of your surgeon.  If its good, it will heal without problems.  If there is necrosis, you could have delayed healing and even contracture develop around the opening. Keep your surgeon updated of any changes.
