Gastroschisis: primary closure using umbilical cord strengthened by a polypropylene mesh.

AIMS: We present a new method of repairing gastroschisis, where the disproportion between the size of the eviscerated intestine and the hypoplastic abdominal cavity could dangerously elevate abdominal pressure if primary closure of the abdominal wall is attempted.

METHODS: We used umbilical cord graft strengthened by a polypropylene mesh to achieve definitive closure of the abdominal wall in a single operation.

RESULTS: This technique provides a mesothelial surface in contact with the intestines, strengthened by a fibrous reaction that prevents future herniation. Five-year follow-up in four patients showed no umbilical hernias and overall excellent results.

CONCLUSIONS: The technique described is useful and easily applicable in children with abdominal wall defects when primary anatomic closure is not feasible. It also prevents future herniation through the anatomical defect of the abdominal wall.
