目的探讨肝门部胆管癌的超声图像特征及术前定位诊断的准确性。方法对55例超声检查时发现左右肝内胆管扩张的患者,仔细观察肝胆管内部情况并存储动态超声图像;对以上患者存储图像总结并与术后病理相对照分析。结果彩超诊断Ⅰ型肝门部胆管癌18例,Ⅱ型7例,Ⅲa型2例,Ⅲb型1例,Ⅳ型3例,术后病理诊断39例为肝门部胆管癌,其中Ⅰ型肝门部胆管癌21例,Ⅱ型9例,Ⅲa型3例,Ⅲb型1例,Ⅳ型5例,彩超定位诊断准确率达79.5%,其中硬化型26例,外生型13例。结论彩超对肝门部胆管癌诊断准确率高,定位准确,为临床手术提供重要参考依据。
Objective To investigate the characteristics of ultrasonography and the accuracy of preoperative localization in hilar cholangiocarcinoma. Methods In 55 cases of patients with intrahepatic bile duct dilatation on ultrasound examination, the internal conditions of hepatobiliary duct were carefully observed and stored dynamic ultrasound images. The above images were stored and compared with postoperative pathology. Results 18 cases of type Ⅰ hilar cholangiocarcinoma were diagnosed by color Doppler ultrasonography. There were 7 cases of type Ⅱ, 2 cases of type Ⅲ a, 1 case of type Ⅲ b and 3 cases of type Ⅳ. Pathological diagnosis of hilar cholangiocarcinoma was 39 cases, of which type Ⅰ There were 21 cases of cholangiocarcinoma, 9 cases of type Ⅱ, 3 cases of type Ⅲa, 1 case of type Ⅲb and 5 cases of type Ⅳ. The diagnostic accuracy of color Doppler ultrasound was 79.5%, of which 26 cases were sclerosing and 13 cases were exogenous. Conclusion The diagnosis of hilar cholangiocarcinoma by color Doppler ultrasonography has high accuracy and accurate positioning, which provides an important reference for clinical operation.
