A case of robot-assisted excision of choledochal cyst, hepaticojejunostomy, and extracorporeal Roux-en-y anastomosis using the da Vinci surgical system.

Choledochal cyst is a rare disease in the Western world, but a high incidence is noted in Asia. Complete cyst excision with Roux-en-y hepaticoenterostomy is the treatment of choice for choledochal cyst, which has been attempted laparoscopically with the advancement of laparoscopic experience. Recently, a telemanipulative robotic surgical system was introduced, providing instruments with wrist-type end-effectors and 3-dimensional visualization of the operative field. Herein, we present a case of robot-assisted correction of a choledochal cyst.
