Reversal

Hi everybody I had a Hartman's procedure done on December 2022 for rectal cancer and have a colostomy bag,I'm trying to gather as much information possible about a possible reversal.I have previously seen my consultant and due to see him again in a couple of weeks when hopefully he can give me a decision as to whether this is possible to do, his concerns to me were that i had aggressive cancer and that I only have 5cms of my rectum left ,has anybody else had this sort of surgery and not been incontinent.
