The role of sigmoidoscopy, radiographs, and colonoscopy in the diagnostic evaluation of pediatric age patients with suspected juvenile polyps.
Juvenile polyps are the most common cause of painless hematochezia in pediatric Age patients after the first year of life. This study evaluated the role of rigid proctosigmoidoscopy, air contrast barium enema examinations, and colonoscopy in the diagnostic approach to 43 such patients. During sigmoidoscopy, polyps were removed from 31 children. On subsequent barium enema examination, more proximal lesions were found in only 4 of these 31 patients, but were seen in 7 of the 12 children who had negative sigmoidoscopic evaluations. Fourteen children had colonoscopy performed. This group included the latter 12 patients plus 2 of the former 4 who again developed hematochezia. Polypectomies were done during 11 of these procedures. Eight of these 11 children had proximal lesions seen during radiographic studies. The diagnostic approach to pediatric age patients with painless hematochezia should include an initial rigid sigmoidoscopic examination. Barium enema evaluation should be reserved for those patients requiring colonoscopy. The latter examination should be performed in all children who have had negative sigmoidoscopic examinations plus those who have had polyps removed from the rectum and then again develop hematochezia.
