Chronic intestinal pseudoobstruction associated with Fetal Alcohol Syndrome

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.
