Yes, and some (on this forum) do it well. After colectomy, small intestine adopts its functios. Lose stools from less absorbed water may be a problem, but even this tends to improve with time. It depends from person to person.
Here's a link to a post from Morecambe who has posted about a colectomy. If this is what you are facing, reading this may be of help. Morecambe posts fairly often and hopefully if this post is seen and you have other questions, you'll be able to get first-hand experience from someone who knows.
