Gastroschisis is classically defined as a right-sided abdominal wall defect, resulting in the herniation of abdominal contents without a protective membrane. Left-sided gastroschisis is exceedingly rare compared to its classical right-sided counterpart, and rates of associated congenital defects appear to be different depending on the laterality of the gastroschisis. This is a case report of a newborn who presented with an abdominal wall defect that was not identified on prenatal ultrasound, with features that were most consistent with a left-sided gastroschisis with isolated omental herniation. A review of the literature suggests that this is the 34th reported case of left-sided gastroschisis. This case report did not receive any specific grant from funding agencies in public, commercial, or not-for-profit sectors. • Left-sided gastroschisis is a rare congenital abdominal wall defect. • This is the 34th reported case of left-sided gastroschisis. • Initial management should focus on preventing hypovolemia and protecting the bowel. • Primary closure is the preferred method of repair, when feasible. • Gastroschisis has a favorable prognosis, with survival rates exceeding 90%.
