General Surgery · Hernia and abdominal wall: gastroschisis association

Sample item

A newborn has loops of bowel without any covering sac protruding through a small defect to the right of a normal umbilical cord. Which associated problem is most characteristic?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Intestinal atresia

Gastroschisis, with exposed bowel and no sac, is associated with intestinal atresia from vascular compromise of the herniated gut, but rarely with chromosomal or major cardiac anomalies. Those are more typical of omphalocele.

Option by option

  • A. Trisomy 18

    Trisomy 18 and other chromosomal anomalies are associated with omphalocele, not gastroschisis.

  • B. Intestinal atresia (correct)

    Correct. Atresia or stenosis from mesenteric vascular compromise is the typical associated anomaly of gastroschisis.

  • C. Neonatal hypoglycaemia

    Neonatal hypoglycaemia is a feature of Beckwith-Wiedemann syndrome, which accompanies omphalocele.

  • D. Cardiac septal defects

    Cardiac defects are common with omphalocele and uncommon with an isolated gastroschisis.
