My grandfather had an ileoanal anastomosis last year. He had colon cancer.
He was in the hospital for about a week, then he came home but was on bed rest most of the time. He also had an external pouch for stool. He really hated that because the part that was attached to his skin would hurt him a lot.
I think doctors can also place internal pouches, I don't know why they didn't do that with him.
