Abstract    Sphincter of Oddi is one complicated and finely-regulated apparatus. It consists of common bile duct sphincter, pancreatic duct sphincter and ampulla of Vater sphincter.  Recently, with better understanding in the anatomical structure and physiological function of sphincter of Oddi, its pivotal roles in maintaining the intra-ductal pressure within biliary tract and pancreatic duct, hydrodynamics of bile and pancreatic juice, aseptic condition within biliary tract and pancreatic duct, and preventing duodenal reflux have been identified.  Hence, the importance in protecting the sphincter of Oddi has been recognized among contemporary biliary surgeons.

Key words: sphincter of Oddi, biliary surgery, Vater ampulla

摘要：

Oddi括约肌（sphincter of Oddi）是机体内一个复杂而精细调节的结构，它是由围绕于胆总管末段、胰管末段及胆胰管汇合Vater壶腹的三部分肌束组成。近年来，随着对Oddi括约肌的解剖结构与生理功能研究的不断深入，人们已认识到Oddi括约肌在维护胆道系统与胰管系统的正常压力、胆汁与胰液的流体力学、胆道与胰管系统的无菌状态以及阻止十二指肠液反流等方面均具有不可替代的关键作用；其结构与功能的受损或被废弃可导致一系列胆胰疾病的发生。因此，当代胆道外科医生应该充分认识到保护Oddi括约肌的重要性。
