胆管损伤（bile duct injury，BDI）是腹腔镜胆囊切除术最严重的并发症之一，若处理不及时或处理不当，甚至危及病人生命。BDI只有少部分是在术中及时发现的，多数是在术后出现症状及体征时才被发现，影像学技术有助于BDI的诊断及明确损伤部位和损伤类型，对制订完善的治疗方案有重要意义。B超、CT检查，因其无创伤性，为疑及BDI者最常用的诊断方法，其余主要经过胆道造影，显示胆道的损伤情况，包括术中胆道造影，或术后磁共振胰胆管造影、经皮经肝胆道造影、内镜下逆行胰胆管造影等。

Abstract    Bile duct injury (BDI) is one of the most serious complications of laparoscopic cholecystectomy. And it would even endanger the patient's life if not promptly handled, or mishandled. Only a small part of the BDI could be found in time during surgery, and more of them are discovered until postoperative symptoms and signs appeared. Imaging technology could help the diagnosis of BDI and make sure of the site and type of injury, which is very important on making complete treatment . B ultrasonic and CT examination are the most commonly used diagnostic methods for suspected BDI because of their non-invasiveness. Other methods are mainly through the way of biliary tract imaging, showing the damage of bile duct, including cholangiography, or postoperative magnetic resonance cholangiopancreatography, percutaneous transhepatic angiography, endoscopic retrograde cholangiopancreatography and so on.
