A newborn has a defect in the anterior abdominal wall located to the right of the umbilicus, with freely floating loops of intestine covered only by a thin layer of fibrin. There is no sac covering the bowel. This presentation is characteristic of:

• A Omphalocele
• B Bladder exstrophy
• C Umbilical hernia
• D Gastroschisis ✓

Explanation

Gastroschisis is a full-thickness defect in the anterior abdominal wall, typically to the right of the umbilicus, where the intestines herniate directly into the amniotic fluid without a protective sac. Omphalocele involves herniation into the base of the umbilical cord, covered by a sac of amnion and peritoneum. Umbilical hernia is covered by skin.
