My Dad also had a perforated colon and was septic. His was due to a tumor that weakened his colon wall. They surgically repaired it and was in the ICU for while but he fully recovered. I know it's hard, but don't loose hope that he will pull through this. Many
My grandma went through this at 83. We didn't think she would make it. She pulled through. It was a realllllly long recovery but, she had her colostomy reversed and she is doing good a year and half later.
