Are there special recipes and dietary guidelines for people who have had a partial colectomy?

Usually not. Depending on the portion of colon removed you may need more fluids to compensate for that lost in the stool. Most limitations in your diet will be learned by trial and error, learning which foods to avoid.
Not usually. However it may depend on what portion of the colon was removed and how much colon remains. Generally a high fiber hi fluid diet will serve most patients well to follow.
