Oddi括约肌具有维持胆管内压力,调节胆囊充盈,控制胆汁流量以及防止肠内容物逆流入胆管等重要生理功能。其病理生理变化与许多胆胰疾病的发生和发展有密切的关系。测定胆管或胰管压力,可以间接了解Oddi’s括约肌的功能。但以往只能通过手术方法来测压,这就限制了它的临床应用价值。 The Oddi sphincter has important physiological functions such as maintaining bile duct pressure, regulating gall bladder filling, controlling bile flow, and preventing intestinal contents from flowing back into the bile duct. The pathophysiological changes and many biliary and pancreatic diseases are closely related to the occurrence and development. Determination of bile duct or pancreatic duct pressure, you can indirectly understand the function of Oddi’s sphincter. But in the past only by surgical methods to manometry, which limits its clinical value.
