Hi Gabriel. Your medical history is so similar to someone I know. The treatment, the stage. He was told by a surgeon the same permanent ileostomy. He got a second opinion at Mayo and got the help of preserving the sphincter. To make the story short, he got the surgery with the ileostomy. After 3 month got the reversal. Now almost 2 month post surgery he is adjusting to the reversal and now feeling much better. Dr is Dr Young-Fadoc. I wish you the best. Keep looking for alternative.
