Prone lateral x-ray is conducted to illustrate the position of the most distal segment of the large bowel and then to differentiate whether it is high or low anal atresia.
Case Discussion
A coin was placed over the anticipated anal opening and the newborn was turned upside down. The distance of rectal shadow to coin is measured.
- >2 cm represents the high type
- <2 cm represents the low type
Anal atresia subtypes can be categorized into two wide categories: high (supralevator) or low (infralevator), depending on the location of the atretic portion.
