What does the abdominal film suggest?
Gaseous distension of bowel loops (predominantly large bowel). Features here are of distal large bowel obstruction.
What are some of the causes of neonatal large bowel obstruction.
- anal atresia - Hirschsprung disease - meconium ileus - meconium plug syndrome
With the history of an imperforate anus, how can the level of obstruction be assessed?
A lateral radiograph in the prone position (or an invertogram) can determine the level of obstruction and assess the distance between the expected position of the anus and the most distal portion of the distended large bowel.
Marked gaseous distension of the large bowel, particularly of the rectosigmoid. Features here are of a distal large bowel obstruction.
