Oddi括约肌:从切开到修复

The sphincter of Oddi:from incision to repair

Oddi括约肌是控制胆胰管通道的阀门,对于维护胆胰管正常生理功能具有不可替代的作用。无论是括约肌成形还是切开术,均可不同程度的破坏Oddi括约肌的功能,造成术后十二指肠液的反流和胆汁细菌污染,增加复发性胆总管结石、反流性胆管炎甚至胆管癌的风险。因此,临床医师应重视保护Oddi括约肌的结构和功能。基于笔者的经验,对于括约肌已被医源性损伤的患者,在肝外胆道可保留的前提下,均应联合经十二指肠括约肌修复术以恢复Oddi括约肌结构的完整性,减少其功能缺失继发的胆胰管并发症。

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.
