It has been performed laparoscopically with the advancement of laparoscopic skill. Recently a telemanipulative robotic surgical system was introduced providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of robot-assisted total excision of a choledochal cyst type I and biliary reconstruction in a 14-year-old girl. No intraoperative complications or technical problems were encountered. An intraabdominal collection occurred and was successfully treated with continuous percutaneous drainage. At one-year follow-up she is doing well without evidence of recurrent cholangitis. Background Choledochal cyst is a rare congenital anomaly of the biliary system in the western countries but has a higher rate of occurrence in Asia. This disorder is usually diagnosed during childhood and is more c ommon in females. After being described first by Vater in 1723 1 choledochal cysts are now classified using the Todani modification of the Alonzo-Lej classification system 2 . The most common is type I consisting of cystic fusiform dilatation of the extrahepatic common bile duct. Untreated choledochal cysts are associated with complications such as recurrent cholangitis acute pancreatitis and cholangiocarcinoma. The standard procedure is complete resection of the cyst with a Roux-en-Y hepati-cojejunostomy anastomosis. Cystoenterostomy is no longer recommended 3 . Recently many centers reported .
