Gastroschisis, malrotation, and chylous ascites.

A newborn infant who had an uncomplicated repair of gastroschisis with modified Ladd's procedure developed chylous ascites when fed. After 7 weeks of nonoperative management with total parenteral nutrition, the ascites resolved. Widening the mesentery may have damaged the lymphatics, and is not necessary for malrotation associated with gastroschisis. Prolonged nonoperative management is recommended for neonatal chylous ascites, avoiding paracentesis if possible.
