External silo reduction of the unruptured giant omphalocele.

Construction of an external silo dressing over the intact omphalocele membrane allows complete reduction of the giant omphalocele with enlargement of the abdominal cavity before surgical intervention, so that primary closure of the abdominal wall can be achieved. Three infants with giant omphalocele containing a central liver were successfully managed by this technique avoiding the complications associated with operative silo placement or simple membrane painting.
