"Apple peel" atresia of the small bowel: prenatal diagnosis of the obstruction by ultrasound.

35-year-old woman developed polyhydramnios during her first pregnancy. Ultrasound confirmed this and showed high bowel obstruction. Delivery was uneventful, the infant was asymtomatic. Abdominal films, however, demonstrated a high jejunal obstruction. At surgery "apple peel" atresia of the small bowel was found. Good outcome.
