title: Recurrent abdominal pain in children revisited: irritable bowel syndrome and psychosomatic aspects. A prospective study.
abstract: BACKGROUND
  Since Apley, more than 40 years ago, concluded that less than 10% of cases with recurrent abdominal pain (RAP) are of organic origin, medical technology has improved, the knowledge has expanded and new methods of investigation have been developed. The lack of organic findings in many children with RAP has led to the conclusion that psychological factors are important.
  
  
  METHODS
  Forty-four children with RAP underwent an investigation programme to find organic abnormalities that might explain the symptoms. Current criteria for irritable bowel syndrome (IBS) in children were used to find out what proportion fulfilled these criteria, irrespective of the organic findings on clinical investigation. A standardized questionnaire, the CBCL (Child Behaviour Checklist), was used to evaluate emotional and behavioural disturbances in children referred for RAP.
  
  
  RESULTS
  Thirteen out of 26 (50%) children with no signs of organic disease fulfilled the IBS criteria as opposed to 7 out of 18 (39%) children in the group with organic findings (P = 0.68). The total score for the CBCL was in the normal range for 32 out of 36 of the children.
  
  
  CONCLUSIONS
  We found a high proportion of children fulfilling the IBS criteria in both groups, thus organic abnormalities have to be excluded before making the IBS diagnosis. The results of the CBCL forms did not show any difference between children with organic versus those with non-organic abnormalities, both groups within the normal range.
