Docs usually emphasize the importance of eating plenty of fiber, to help sweep things through the intestine. It isn't foolproof, one can still get some stuff festering in a pouch, but the fiber can't hurt and could help. Other than that, like they say, surgery is the fix. My wife had 1/3 of her colon removed in 2008 and it ended years of agony, but now she has to stay close to a bathroom. Stuff moves through her much faster and she never knows if it's gas or worse until she sits on the throne... can't take the chance.
