Yersinia enterocolitica is a well-known cause of acute enteritis. In its classical form, the disease is self limiting and is characterized by abdominal pain which, in some cases, may resemble acute appendicitis, thus leading to emergency appendectomy. In adults and children older than 7 years, a chronic form is also described, with recurrent abdominal pain, constipation, mesenteric lymphadenopathy, reactive arthritis, Reiter syndrome, and other autoimmune-like disorders often linked with HLA B27 antigen positivity. We report on a case of intestinal obstruction 1 year after emergency appendectomy as the first clinical manifestation of Yersinia enterocolitica infection. To our knowledge, this is the first report in Italy of this clinical association.
