Familial combined duodenal and jejunal atresia.

Combined duodenal and jejunal atresia is extremely uncommon. The familial occurrence of congenital duodenal and small bowel atresia is even more unusual. To the authors' knowledge, this is the first report of two siblings with simultaneous duodenal and jejunal atresia who underwent successful surgical repair. The report may support the genetic origin of some forms of high intestinal atresia.
