Chyloperitoneum: a postoperative complication after repair of tracheoesophageal fistula.

Chyloperitoneum is rare condition that can occur in response to various pathologic process. The authors described a newborn baby who had chyloperitoneum after primary surgical repair of esophageal atresia with tracheoesophageal fistula (Gross type C). This probably resulted from iatrogenic damage of the thoracic duct during ligation of azygous vein resulting in leaking lacteal within the intestinal wall. Biochemical analysis of ascitic fluid, plasma, and milk formula for triglyceride and cholesterol level can differentiate neonatal gastric intestinal perforation.
