Abstract
Purpose: With increasing frequency, Yersinia enterocolitica is being recognized as an important bacterial cause of acute gastrointestinal infection with abdominal pain. In addition, the association of Y. enterocolitica infections with acute appendicitis has been suggested. This study was undertaken to ascertain whether Y. enterocolitica is a possible infectious agent in acute appendicitis. Methods: Between December 2007 and April 2008, 162 patients who underwent appendectomy for presumed appendicitis, enrolled in this prospective study. After surgical excision of appendix, a portion of each specimen was cultured for Y. enterocolitica with highly selective media (Cefsulodin-Irgasan-Novobiocin agar). Results: Pathologically, 150 of the patients had appendicitis and 12 patients had normal appendices. Only one of the 150 patients (0.7%) with appendicitis was found to be culture positive for Y. enterocolitica, while it was not detected from normal appendices. Conclusion: The authors were unable to implicate Y. enterocolitica as a major pathogen in acute appendicitis within the Seoul area. However, we thought there to be more need for investigation for association of Y. enterocolitica with acute appendicitis over a broader area and season.
