The intestinal obstruction of duodenal atresia needs urgent differential diagnosis from malrotation with its risk of midgut volvulus and gangrene. There is an uncommon variant with a high incidence of familial recurrence, and a significant association with Down's syndrome, although the majority of the babies are otherwise normal. Oblique end-to-end anastomosis around the atresia is the preferred treatment and has a high success rate.
十二指肠闭锁引起的肠梗阻需要与旋转不良紧急鉴别诊断，因为旋转不良有发生中肠扭转和坏疽的风险。有一种不常见的变异型，家族复发率高，且与唐氏综合征有显著关联，不过大多数患儿在其他方面是正常的。围绕闭锁处进行斜行端端吻合术是首选的治疗方法，成功率很高。
