Abstract:
The sphincter of Oddi is a valve that controls the biliopancreatic duct and plays an irreplaceable role in maintaining normal physiological functions of the biliopancreatic duct.However,sphincteroplasty and sphincterotomy may cause varying degrees of damage to the function of the sphincter of Oddi,which may further result in postoperative reflux of duodenal fluids and bacterial contamination in bile and increase the risks of recurrent common bile duct stones,reflux cholangitis,and even cholangiocarcinoma.Therefore,clinical physicians should protect the structure and function of the sphincter of Oddi.Based on our experience,under the premise that the extrahepatic bile duct can be preserved,patients with iatrogenic injury of the sphincter of Oddi can be treated with transduodenal sphincteroplasty to restore the structural integrity of the sphincter of Oddi and reduce biliopancreatic duct complications secondary to loss of function.
