定义
任何因干扰胎儿正常生长和分化导致的食道先天性缺陷。这种缺陷可在胚胎发育的任何阶段出现，在类型和严重程度上差异很大，由多种决定因素引起，包括基因突变、染色体畸变、致畸剂和环境因素。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 oesophagus 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.

后组配轴 Postcoordination
后组配是在主干编码之后追加的可选扩展轴（如侧别、具体解剖部位、严重程度），用于把「部位 + 侧别 + 病程」等细节一次表达完整。只有标注「必填」的轴在组合编码时必须给出，其余可留空。
