Abstract: Bilioenterostomy with a wide variety of techniques is a common surgical operation in digestive surgery. Each of these surgeries has its own advantages and disadvantages. At present, Roux-en-Y choledochojejunostomy seems to be the dominant surgery, while other operations are used in some particular circumstances. Furthermore, some modified surgeries for bilioenterostomy have been conducted with the deepening understanding of the complications. Additionally, different kinds of new facilities and techniques have been applied to bilioenterostomy. Despite the controversy on specific issues, reasonable choice of bilioenterostomy should follow the principles of specific purpose, correct choice and reliable effect. In other words, whether or not using bilioenterostomy should be considered correctly from the whole system, and then surgical methods should be accurately chose for patients, and finally avoiding the technical errors and guaranteeing the surgical effects.
