[Investigations on the incidence of Yersinia enterocolitica - infections in the various forms of appendicitis, cholelithiasis, and goitre (author's transl)].

Out of a total of 3347 patients operated on for acute appendicitis 125 were found to be infected with Yersinia enterocolitica. Histological examination revealed a catarrhal-purulent inflammation or a phlegmonous-gangrenous inflammation in 58,6%. This detection of Yersinia enterocolitica does not justify the omission to perform appendectomy, because true appendicitis cannot be ruled out.
