Abstract
Omphalocele is an abdominal wall defect involving the umbilical ring which results in visceral herniation of small and large intestine, liver, spleen and sometimes gonads. The covering of the herniated viscera by a fused membrane consisting of peritoneum, Wharton's jelly and amnion projects viscera from mechanical injury and exposure to chemical irritants in amniotic fluid.
Omphalocele is usually diagnosed before birth, is variable in size, and is frequently associated with chromosomal and somatic anomalies, syndromes, and variable degrees of pulmonary hypoplasia which can be lethal.
In this article we examine surgical closure options for omphaloceles ranging from early primary fascial repair for small omphaloceles to a staged repair, often facilitated by an amnion preserving silo, which may be necessary for giant omphaloceles that cannot be closed primarily. We also review some of the adjuncts to abdominal wall reconstruction including tissue expansion and mesh. Conservative management (paint and wait) of giant omphaloceles is described elsewhere.
