신생아 외과질환에서의 재태기간과 출생체중의 관계

Abstract

Gestational age and birth weight are closely correlated with each other, and these are major determinants of perinatal morbidity and mortality. Many neonates with congenital anomalies are premature and of low birth weight. Intrauterine growth retardation can be caused either by congenital malformation itself or by the conditions brings about congenital malformation.

In the cases with prenatal diagnosis, it is ideal for a mother to deliver an affected fetus at full-term for maximal fetal growth and a better prognosis, But several factors, such as fetal growth, organ maturation and the detrimental effect of malformation, must be considered for the optimal time of delivery. Therefore, it is important whether the affected fetus gains body weight continuously throughout the intrauterine period.

We found that midgut volvulus, esophageal atresia, Hirschsprung's disease, and jejunoileal atresia showed a positive correlation between gestational age and birth weight. On the contrary, meconium peritonitis, duodenal atresia, diaphragmatic hernia, anorectal malformation, gastroschisis and omphalocele did not gai body weight through the 3rd trimester of pregnancy.

We consider that this finding will aid the optimal time of delivery of the fetus with congenital malformation, diagnosed prenatally.
