RESUMO
BACKGROUND: Enteric nerve cells begin to mature during the last trimester of pregnancy and become mature only after birth. The degree of maturation seems to be related to bowel motility. CASE REPORT: A girl was born from a pregnancy complicated by hydramnios, and did not pass meconium before the 64th hr of life. Barium enema on day 4 showed a left microcolon with no distension of the transverse colon. Tests for cystic fibrosis were negative. On day 12, the patient presented with septicemia due to Pseudomonas maltophylia. Parenteral alimentation by central catheter was instituted. Surgical rectal biopsy showed that the number of ganglion cells was normal but the cells were immature. Progressive feeding was possible for the 3rd month of life. A second rectal biopsy at 3 1/2 months showed some remaining immature ganglion cells. CONCLUSION: Immature ganglion cells can account for neonatal functional intestinal obstruction, as has been established for the small left colon syndrome. The progressive loss of symptoms seems to be correlated with histological maturation of the neurological apparatus of the large bowel. Severe complications, such as occlusion, sepsis, nutritional disorders can occur during this long period of functional intestinal obstruction.
