Hayleybaby,
When my rectum was removed, the surgeon left the wound
open. I packed it twice a day with saline-filled gauze until it healed up, which took about
10 months. Some surgeons sew the hole shut during surgery. Mine left it
open, because I had problems with fistulas, and she wanted to make sure they were all gone. When you have it done and are all healed up, your butt will look like a butt, but there won't be a hole there anymore (if that makes sense)
