奥狄括约肌测压是诊断奥狄括约肌功能障碍的金标准。但由于奥狄括约肌生理解剖位置的特殊性，人们对其研究仍有一定局限性。本文旨在综述奥狄括约肌和胆胰管测压技术发展演进过程、各种导管的特点及测压相关并发症等。

Objective:To evaluate the safety and reliability of percutaneous management of benign extrahepatic biliary strictures with biliary duct dilatation and large-bore catheter placement .Methods:The clinical data of 17 patients at Shengjing Hospital from Mar 2017 to Mar 2020 was retrospectively analyzed.Results:There were 7 cases of bilioenteric anastomotic strictures and 10 cases of iatrogenic biliary tract injury strictures (6 cases of Bismuth type Ⅰ and 4 cases of Bismuth type Ⅱ). Fourteen of the 17 patients completed the treatment with a success rate of 82.3%.The catheter was gradually upsized to 22-24Fr.Catheters were left in place for 6-9 months (median time 7.6 months). Patients were followed up for 6-28 months (median follow-up time was 19 months), no recurrent stricture occurred.Conculsion:Percutaneous management of benign extrahepatic biliary strictures with bile duct dilatation and placement of large-bore catheter is a safe and effective minimally invasive treatment method.
