[Acute appendicitis in children. Experience at a general hospital].

In order to establish a guide for the diagnosis of acute appendicitis, we reviewed the charts of patients with appendectomy. In a 7-year period, 385 patients were studied. The age range was 3 to 15 years. In 53% there was an administration of medications prior to surgery. Perforated appendicitis was found in the majority (53%) of the cases. We could not find any association between age and perforation. Only localized, persistent abdominal pain, peritoneal irritation, anorexia, and vomiting were useful for differential diagnosis. In patients with acute appendicitis (p greater than 0.05), leukocytosis (greater than 10,000/mm3), neutrophilia (greater than 70%) and bands (greater than 3%) were observed in 80% of the cases. The frequency of complications was elevated (39.5%), and the mortality was five times higher than referred in other studies. We propose an algorithm for both opportune diagnosis and treatment of the disease.
