However, atresias of the small intestinal tract associated with Hirschsprung disease are extremely rare. We describe an infant born with both ileal atresia and Hirschsprung disease. This is the 19th known report of the case of an infant who had ileal atresia associated with Hirschsprung disease.展开更多
先天性巨结肠(Hirschsprung′s disease,HD)又称先天性无神经节细胞症,是小儿外科常见的先天性消化道畸形之一,发病率约20/100000,男性稍高于女性,有一定的遗传易感性,病因复杂,其确切病因尚不十分清楚,目前有遗传易感性、...先天性巨结肠(Hirschsprung′s disease,HD)又称先天性无神经节细胞症,是小儿外科常见的先天性消化道畸形之一,发病率约20/100000,男性稍高于女性,有一定的遗传易感性,病因复杂,其确切病因尚不十分清楚,目前有遗传易感性、肠壁内微环境及环境因素异常等学说[1]。因很多研究认为肠神经系统(enteric nervous system,ENS)中神经化学递质异常可能是 HD 发病的根本原因,故 HD 相关神经递质研究一直是 HD 病因研究的热点之一。展开更多
