My father has had a colostomy for over 40 years and has had surgery changing him to an ileostomy. Over the past 40 years, he has used bags that do not use any sticky adhesive on the
wafer, just a belt and a plastic ring and they've been fine, never leaked. Now switching to the ileostomy, he has changed to using the wafer and bag system with the adhesion. No matter what we try, they are not sticking for longer than a couple hours. We are changing the bags up to 4 times a day.
