Irritable bowel syndrome in children

: The irritable bowel syndrome (IBS) is characterized by alteration in bowel habits (i.e., constipation and/or diarrhea) and abdominal pain, and is most common gastrointestinal disorder in adults. The recurrent abdominal pain (RAP) in children is similar to IBS in adults except bowel habits, but there is no settled conception of IBS in children. In our department, diagnosis of pediatric IBS will be made if the child has; #1 functional gastrointestinal disorders without organic diseases, #2 abdominal pain and other gastrointestinal symptoms continuing more than 3 weeks, #3 psychogenic background factors. We experienced 63 cases of IBS (23.5% in all 268 cases) from April 1990 to March 1992 at our pediatric digestive outpatient clinic. They ranged from 4 to 15 years old and about 60% of them were elder than 13 years old. Psychogenic factors were usually related to environment of school life and home. Careful history taking and routine examination were most important for the diagnostic approach. Management of this disease included counseling and drug therapy. Almost all cases reached much better condition 1 to 6 weeks after the therapy started. The combination therapy with psychologist was required in a few cases.
