Acute Abdominal Pain in Children

Abstract

During a twelve-month period, 416 children with acute abdominal pain required emergency admission to Southampton General Hospital; 46% had operations. Appendicitis was the commonest organic cause of acute abdominal pain identified (31%). Constipation (9%) can present as acute abdominal pain simulating appendicitis. All children should have a urine sample examined microscopically and the finding of significant pyuria is suggestive, but not diagnostic, of a urinary tract infection (7%). Mesenteric adenitis, which can only be diagnosed with certainty at laparotomy, was less common (4%). Despite careful clinical assessment and follow up, 45% of children in this series remained undiagnosed. Sedation but not analgesia may assist in the diagnosis of the acute abdomen in children.
