The use of indium 111 leukocyte scans in children with inflammatory bowel disease.

Indium 111 leukocyte (WBC) scans have been used in the investigation of inflammatory bowel disease in recent years, but their use in children is not well described. We reviewed our experience with 281 indium 111 scans over an 8-year period in a total of 109 children with inflammatory bowel disease (Crohn's disease 70, ulcerative colitis 39). One hundred twenty-eight indium 111 scans done within 2 weeks of a radiographic contrast study, endoscopic examination, or surgical procedure were evaluated for diagnostic accuracy. Analysis showed that indium 111 scans were accurate when compared with conventional diagnostic tests and operative findings. This noninvasive imaging technique can play a useful role in the management of children with inflammatory bowel disease.
