奥迪氏括约肌在控制胆汁胰液排出活动中具有重要作用。以往的动物实验及临床研究都表明该括约肌具有分期收缩的特性。动物实验中,奥迪氏括约肌的分期收缩可短暂地阻断胆汁胰液的流动,但其主要作用是促使少量液体由胆总管排人十二指肠。临床上在人体中所观察到的现象与上述机制相仿。然而,在主动排出胆汁与被动流出之间的平衡机制仍未清楚。作者在此研究中,以胆石症胆总管探查T管引流 Audi sphincter plays an important role in controlling bile pancreatic excretion. Previous animal experiments and clinical studies have shown that the sphincter has the characteristics of staging. In animal experiments, the staging of the Oddi’s sphincter temporarily blocks the flow of bile pancreatic juice, but its primary role is to encourage small amounts of fluid to drain from the common bile duct to the duodenum. Clinically observed in the human body and the mechanism similar to the above. However, the mechanism of balance between active excretion and passive excretion remains unclear. In this study, the authors used cholelithiasis to explore the T tube drainage of the common bile duct
