大肠结构发育异常

定义

干扰胎儿正常生长和分化导致的大肠先天性缺陷。这些缺陷可能出现在胚胎发育的任何阶段，类型和严重程度差异很大，由多种决定因素引起，包括基因突变、染色体畸变、致畸因子和环境因素。大多数发育缺陷在出生时就很明显，特别是任何结构畸形，但有些在出生后显现。

Any congenital defect of large intestine that results from interference with the normal growth and differentiation of the fetus. Such defects can arise at any stage of embryonic development, vary greatly in type and severity, and are caused by a wide variety of determining factors, including genetic mutations, chromosomal aberrations, teratogenic agents, and environmental factors. Most developmental defects are apparent at birth, especially any structural malformation, but some become evident later.
