In summary, the causes of GI bleeding in infancy and childhood are varied, ranging from congenital and hereditary disorders to those more commonly seen in the adult population. Many causes of GI bleeding in the pediatric population are restricted to a narrow range regarding age of onset, frequently enabling the physician to narrow the differential diagnosis before proceeding with invasive investigation; however, GI bleeding may involve any portion of the intestinal tract, from mouth to anus, as in adulthood, and many causes common to the adult population also must be considered.
总之，婴幼儿和儿童胃肠道出血的病因多种多样，从先天性和遗传性疾病到成人中更常见的病因都有。儿科人群中许多胃肠道出血的病因在发病年龄方面局限于较窄范围，这常常使医生在进行侵入性检查之前就能缩小鉴别诊断范围；然而，与成人一样，胃肠道出血可能累及从口腔到肛门的肠道任何部位，也必须考虑许多成人中常见的病因。
