Abstract：
:Diagnosis and intervention in pediatric GI bleeding is the shared responsibility of pediatric endoscopists, radiologists, and surgeons. Brisk hemorrhage, though alarming, is most often self-limited; few cases require urgent surgery before diagnostic evaluation is accomplished. The choice between endoscopic and radiographic evaluation varies with the differential diagnoses being considered and with local referral patterns. Many imaging options exist for assessing GI bleeding in children, but these options are generally narrowed by clinical history and age-appropriate differential possibilities.
