[Appendicitis, pseudoappendicitis and Crohn's disease].

Abdominal pain which is a basic symptom of Crohn's disease was in a group of 53 patients treated in 1981-1982 at the Surgical Clinic of the Third Medical Faculty in Prague 10 the initial symptom in 73.3% of the patients. The inflammation was most frequently in the terminal ileum and in the ileocaecal region, in the authors' group in 49.0% and 30.2% resp. In 18 patients appendectomy was performed, incl. 10 where it was performed a long time before the development of the first complaints caused by Crohn's disease. In these patients the authors do not assume, because of the long symptom-free period, that there existed a direct relationship with Crohn's disease which developed later. In six patients during laparotomy performed on account of pain in the right hypogastrium acute terminal ileitis, the first stage of Crohn's disease, was detected. In two patients the initial finding was granulomatous appendicitis.
