A choledochal cyst is a swelling / widening or dilatation of the bile ducts. Choledochal cysts (CCs) are diagnosed in children and adults, although most (80%) develop in children younger than 10 years. Choledochal cysts are also 4 times more common in females than males, The exact cause of CCs is unknown, but described as a reflux of pancreatic enzymes into the biliary tree through an anomalous pancreaticobiliary duct union (APBDU), thereby leading to biliary dilation. Although rare in the general population, APBDU has been reported in more than 80% of children with CCs.The classic symptoms in children are intermittent abdominal pain, jaundice, and the presence of a right upper quadrant abdominal mass. We present a case of 2 year-old girl with choledochal cysts and pancreatitis as a complication. She underwent biliodigestive bypass cholesis-    tojejunostomy  jejunojejunostomy and cholecystectomy, got total parenteral nutrition for 2 days and treated with intravenous meropenem. There was improvement in clinical manifestations after surgery.
