Small Bowel Permeability to 51Cr‐EDTA in Children with Recurrent Abdominal Pain

ABSTRACT. Small bowel permeability was investigated in 87 children with recurrent abdominal pain by measuring the 24‐h urinary excretion of orally administered 51Cr‐EDTA. The mean excretion was 3.64%± 1. 49% per 24 h. The difference between the mean urinary excretion in children with recurrent abdominal pain and control children (2.51 %± 0.70 %), was significant (p<0.01, two sample t‐test). The increased small bowel permeability in children with recurrent abdominal pain might indicate an intestinal etiology for the patients' complaints.
