If intestinal obstruction was diagnosed prenatally on ultrasound, plain radiographs should be performed after birth to confirm the diagnosis. If the plain films show signs of obstruction, contrast studies usually should be performed to help localize and establish the cause of the obstruction before proceeding to surgery, unless urgent intervention is indicated because of pneumoperitoneum or signs of shock or peritonitis.
