The original description of regional ileitis, now known as Crohn's disease, emphasized involvement of the terminal ileum. Four decades ago colonic involvement with Crohn's disease was recognized as a relatively common occurrence. Now we recognize that Crohn's disease may involve virtually any location in the gastrointestinal tract, from mouth to anus. Involvement of the upper gastrointestinal tract, although relatively uncommon, is important to recognize, because it may result in atypical clinical presentations and may affect treatment decisions, both medical and surgical.
