An analysis of ultrasound scanning as a guide in determination of "high" or "low" imperforate anus.
The classic upside-down abdominal roentgenogram and the use of pelvic reference points have frequently been inaccurate in assessing the level of the distal pouch in patients with imperforate anus. The ultrasonic study described is different from that previously reported and allows more precise localization of the distal rectal pouch. A review of our experience allows us to make certain definitive statements about this diagnostic modality.
