  • Title: Preoperative clues to Crohn's disease in suspected, acute appendicitis. Report of 12 cases and review of the literature.
    Author: Oren R, Rachmilewitz D.
    Journal: J Clin Gastroenterol; 1992 Dec; 15(4):306-10. PubMed ID: 1294636.
    Abstract:
    Twelve patients who underwent laparotomy for suspected acute appendicitis were found to have Crohn's disease of the terminal ileum. Appendectomy was performed in all although in only four patients was the appendix grossly inflamed. Postoperative complications, either abscess or fistula, developed in four patients (33%). Careful investigation of the records revealed some preoperative diagnostic clues: a history of recurrent abdominal pain and/or diarrhea (83%), physical examination revealing normal temperature (50%), and laboratory results compatible with a chronic process such as microcytic anemia (33%) and hypoproteinemia/hypoalbuminemia/hypocholesterolemia (50%). As the differential diagnosis between Crohn's disease and appendicitis is difficult and the surgical approach to the appendix in the presence of Crohn's disease is controversial, we illuminate some practical points in the preoperative evaluation of these patients and deal with the question of whether appendectomy should be performed in these patients.
