Abstract:
Congenital anorectal malformation (ARM) is one of the most common gastrointestinal congenital diseases, accounting for 1/4 in digestive tract malformation, and is one of the congenital malformations in routine surveillance by the World Health Organization. Because of the variety of risk factors and the complexity of the pathological changes, etiology of ARM is still not clear. It is mostly considered that ARM is resulted from hereditary factors and environmental factors in the development of embryogenesis. Through animal experiments, scholars have found that Hox, Shh, Fgf, Wnt, Cdx and TCF4, Eph and ephrin play crucial role during the development of digestive tract. When the genes/signaling pathway dysfunction occurs, ARM may happen. In addition, ARM is related to the external factors in pregnancy. Because of the complexity of related factors in the development of human embryogenesis, the research progress of human ARM is very slow. This paper reviews relevant literatures in genetic factors and environmental factors, in order to provide the theoretical basis for the treatment and prevention of ARM.
