Alcohol acts as a teratogen in the fetus, resulting in prenatal or postnatal growth failure, characteristic facial dysmorphic features, and central nervous system dysfunction. The toxic effects of alcohol on the developing brain are well recognized, but gastrointestinal neuropathy has not been described in fetal alcohol syndrome (FAS). Five children with FAS presented in infancy with signs and symptoms suggestive of chronic intestinal pseudoobstruction. They were not able to sustain adequate caloric intake by mouth, and all required prolonged special methods of alimentation. We performed antroduodenal manometry in these children to determine whether their symptoms were associated with a gastrointestinal motility disorder. All patients had abnormally propagating phase III-like episodes during fasting (retrograde in four, simultaneous in two). Persistent clusters of stationary contractions were a prominent feature in two patients. In utero neurotoxicity of alcohol may not be limited to the central nervous system, but may also cause an enteric neuropathy presenting in infancy as chronic intestinal pseudoobstruction.
酒精对胎儿具有致畸作用,可导致产前或产后生长发育迟缓、典型的面部畸形特征以及中枢神经系统功能障碍。酒精对发育中大脑的毒性作用已得到充分认识,但胎儿酒精综合征(FAS)中的胃肠道神经病变尚未见报道。5例患有FAS的儿童在婴儿期出现提示慢性肠假性梗阻的体征和症状。他们无法通过口腔维持足够的热量摄入,均需要长期采用特殊的营养供给方法。我们对这些儿童进行了十二指肠测压,以确定他们的症状是否与胃肠动力障碍有关。所有患者在禁食期间均出现异常的类似Ⅲ期传播性发作(4例为逆行性,2例为同步性)。持续性的静止性收缩簇是2例患者的突出特征。酒精在子宫内的神经毒性可能不仅限于中枢神经系统,还可能导致婴儿期出现慢性肠假性梗阻的肠神经病变。
