I'd try and convince him to get the Colostomy bag. I had 3 during my battles with colorectal cancer, I don't have one anymore but for along time I wished I had.. It was so hard to get my body right, but I take the max dose of loperamide when I have to go somewhere. But I also have to take laxatives. It's a really tough thing to balance. But really an Ostomy isn't that bad and it's way better than pooping your pants. I'm tiny and could hardly wear jeans or a waist band. It was uncomfortable for me, but I still wish I would have opted to keep it sometimes.
