A novel association of duodenal atresia, malrotation, segmental dilatation of the colon, and anorectal malformation.

We describe two female neonates who suffered from four gastrointestinal anomalies, including duodenal stenosis or atresia, malrotation, segmental dilatation of the colon, and anorectal malformation. Each patient was managed by two or three operations, resulting in good bowel movements. Since this is the first report of four gastrointestinal anomalies, these cases may provide clues to elucidate the etiology of gastrointestinal tract developmental abnormalities.
