Management of the appendix in young patients with Crohn's disease.

Sixty-six young patients (average age, 17.2 years) underwent intestinal operations for Crohn's disease during a 14-year period at the UCLA Hospital. Nine had undergone previous appendectomy for suspected appendicitis, and in seven subsequent enteric fistulae and/or obstruction involving the cecum developed. None of the appendices were acutely inflamed. During the same period, a total of 125 children with Crohn's disease underwent medical or surgical care, and in none did acute appendicitis develop. Of the 66 patients under 22 years old who required intestinal resection, 60 had removal of the cecum. In a child with ileal Crohn's disease, rarely should a normal appendix be removed because of the high likelihood of complications and the low incidence of subsequent appendicitis.
