Antenatal Diagnosis of Hirschsprung Disease

Abstract

Isolated prenatally diagnosed large colonic dilatation in late third trimester raised suspicion of colonic obstruction. On further investigating, after the baby failed to pass meconium after 24 h, with radiograph and barium enema confirmed the diagnosis of Hirschsprung disease. Even though the sensitivity and predictability of antenatal ultrasound is limited, prenatally diagnosed colonic dilatation should be investigated further to confirmation of any underlying colonic obstruction and for timely intervention to decompress the dilated loops and to avoid any life threatening complications.
