摘要：Congenital obstruction of the digestive tract is one of the most common surgical neonatal pathologies, affecting 1/1000-1/2000 neonates. The anatomical obstructions can be intrinsic or extrinsic to the bowel, with the main cause being ileal atresia. Prenatal diagnosis is possible via an ultrasound scanning of the fetus, although only possible in late pregnancy and with a varying sensitivity. In comparison to diagnosing postnatally, it improves the prognosis as it allows for better management of cases at fetal medicine units and specialist centres, where there are multidisciplinary team members available. These include obstetricians, neonatologists and paediatric surgeons. Frequently, congenital intestinal obstructions are associated with chromosomal abnormalities, malformations of other organs and genetic diseases such as cystic fibrosis. Fundamentally the diagnosis depends on highlighting the cause, the level of the obstruction and the length of the intestine that is affected, as well as the weight of the neonate and gestational age at birth. We present a case diagnosed prenatally, at 32 weeks gestation, of an intestinal obstruction associated with an ileal volvulus and meconium ileus of a fetus affected by cystic fibrosis.
