I am sorry your Dad is going thru this.
I have not had my rectum removed. I have a colostomy and have discharge multiple times a day. I have spoken to my CRS regarding the removal of my rectum and anus and he did state that there are times when there are issues that could occur such as pain or leakage that do not go away. It does not happen often but once in a blue moon it does happen. He did act like they could probably go back in and try to fix it but there were no guarantees.
For me....I use calmoseptine...over the counter skin protectant...and those really small pads for when the leakage is really bad. I wish I could help more.
