I also have a lot of "accidents" at night and at work. I've worn an overnight sized maxi pad 24/7 for the past several years. It is a bummer but at least I can work. I have waterproof square pads which i put on my bed each night to protect mattress. I am curious about the lop-sided stomach too. I have had 3 iliestomoies 2 on 1 side and 1 on the other so always assumed the scar tissue was worse on the one side. In one of my scans they noted a hernia (about 5 yrs back) but I haven't followed up with this. They didn't seem real concerned at the time. My stomach is really firm/hard and one side is bigger than the other. I have a follow up with my GI soon and will ask about the hernia. It seems like doctors don't want to go anywhere near someone with scar tissue like we all have.
