Chylous ascites after excision of a choledochal cyst in a child.

We report a case of chylous ascites developing 2 weeks after excision of a choledochal cyst with a Roux-en-Y hepaticojejunostomy. Despite the failure of the initial attempts to resolve the chylous ascites by fasting, subsequently, we successfully treated the patient's chylous ascites with intravenous somatostatin. No obvious adverse side effects occurred during the use of somatostatin. To the best of our knowledge, this is the first report of chylous ascites after choledochal cyst excision in children, which was successfully treated with somatostatin. Somatostatin may be considered as a therapeutic option of managing pediatric postoperative chylous ascites.
