A fifty eight cases of congenital intestinal atresia were analized. There were 40 survivals and the mortality was 31%. Associated anomalies were found frequently in duodenal atresia and high jejunal atresia, and they tended to be multiple and life-threatning. Since these anomalies affect the mortality, their management would be the key point in the treatment or congenital intestinal atresia, which was especially true in duodenal atresia and high jejunal atresia within 20cm distal to ligament of the Treitz.
