**2. Epidemiology**

The incidence of duodenal atresia is approximately 1 in 5000–10,000 live births, and it affects boys more than girls [1]. More than 50% of affected children have other associated anomalies, most commonly trisomy 21 (30% of duodenal atresia cases), heterotaxy syndrome, and congenital cardiac defects [2, 3]. Other less common associations include annular pancreas, malrotation, oesophageal atresia, genitourinary anomalies, anorectal malformation, and concomitant intestinal atresia [4].
