Multiple gastrointestinal atresias: sonography of associated biliary abnormalities.

The pre-operative finding of biliary ductal dilatation in the setting of multiple gastrointestinal atresias has not been previously reported. This paper illustrates the sonographic findings in two neonates with multiple gastrointestinal atresias from the prepyloric region to the rectum. Biliary ductal dilatation was seen in both patients and highly echogenic, mobile intraluminal bowel debris secondary to calcified meconium was evident in one. Post-operative biliary gas was demonstrated on sonography in one case.
