ABSTRACT

Congenital duodenal atresia is the most common cause of perinatal intestinal obstruction. Abdominal distension and projectile vomiting are the specific symptoms of neonatal gastro-intestinal obstruction. The incidence of duodenal atresia is between 1 in 2,710 and 1 in 10,000 live births.1 Most cases are thought to be failure of recanalization of the duodenal lumen during embryonic period.2 Duodenal atresia is associated with a high incidence of other associational anomalies, including esophageal atresia, biliary atresia, congenital heart disease and vertebral anomalies. Prenatal diagnosis, the ealry operation and the facotrs such as prematurity, combined abnormalities, nutirtion have a significant influence on complication and mortality.3,4 We report a case of congenital duodenal atresia diagnosed by ultrasonography prenatally in Andong general hostpital at 26 gestational weeks and operated the 7th day of cesarean section in Yeungnam university hospital with a brief review of literature.
