    Abstract:
    The authors evaluated the diagnostic role of sigmoidoscopy, colonoscopy, and double contrast radiology in 103 children with rectal bleeding, with or without other gastrointestinal symptoms. The children's mean age was 44 months, with a range from 1 month to 12 years. In 74.5% of the subjects investigated, visual inspection of the anus and sigmoidoscopy with rectal biopsy disclosed a positive diagnosis. Of the remaining patients, a conclusive diagnosis was reached by either colonoscopy or double contrast radiology in all but six patients. These six, with mild painless hematochezia, remained without a diagnosis. The diagnostic procedure in pediatric patients with rectal bleeding should include an initial visual inspection of the anus, and sigmoidoscopy; air contrast enema and colonoscopy should be performed only in children whose sigmoidoscopy is negative, in diagnostic assessment of inflammatory bowel disease, and in cases of recurrent bleeding after removal of rectal polyps. Colonoscopy is important also in the follow-up examination of children with inflammatory bowel disease and allows the removal of polyps located in the proximal colon.
