Mechanic intestinal obstruction--a possible presentation of perforated appendicitis.

A 61-year-old man presented with diffuse abdominal pain, diarrhea, vomiting and fever. On the initial diagnosis of gastroenteritis the patient received the antibiotic ofloxacine for one week. On admission plain abdominal radiograph suggested a mechanic intestinal obstruction. In computed tomography a conglomerate tumor in the ileocecal region was seen and the patient underwent laparotomy. The conglomerate tumor was mobilized and an abscess opened, which was caused by a perforated appendicitis. After the operation the patient improved immediately and had an uneventful postoperative course. He was released and did not suffer from gastrointestinal symptoms the following 16 months of follow-up. The present case shall set forth that perforated appendicitis can clinically present as intestinal obstruction. Although a rare complication, perforated appendicitis should therefore even be considered in cases of mechanic intestinal obstruction of unknown cause.
