双通道超声造影检查在肝门部胆管癌分型诊断及胆道低位梗阻病因诊断中的应用价值

Application value of dual-channel contrast-enhanced ultrasound in classification of hilar cholangiocarcinoma and etiological diagnosis of low bile duct obstruction

目的:研究双通道超声造影检查(DCUS)在肝门部胆管癌分型诊断及胆道低位梗阻病因诊断中的应用价值。方法:选择西双版纳州人民医院收治的90例梗阻性黄疸患者作为研究对象。对这些患者均进行手术治疗。术前对其实施常规的超声造影(US)检查,术中对其实施DCUS检查。以对其进行术后病理学检查的结果为依据,比较用US检查与DCUS检查对其肝门部胆管癌进行分型诊断及对其胆道低位梗阻进行病因诊断的准确率。结果:与用US检查相比,用DCUS检查对90例患者的肝门部胆管癌进行分型诊断的准确率更高,P<0.05。与用US检查相比,用DCUS检查对90例患者的胆道低位梗阻进行病因诊断的准确率更高,P<0.05。结论:用DCUS检查对梗阻性黄疸患者的肝门部胆管癌进行分型诊断及对其胆道低位梗阻进行病因诊断的准确率较高。

Objective:To study the application value of dual-channel contrast-enhanced ultrasound(DCUS)in the classification of hilar cholangiocarcinoma and etiological diagnosis of low bile duct obstruction.Methods:90 cases of obstructive jaundice in Xishuangbanna People’s Hospital were selected as the research object.All of these patients underwent surgical treatment.Routine contrast-enhanced ultrasound(US)examination was performed before surgery,and DCUS examination was performed during surgery.Based on the results of postoperative pathological examination,the accuracy of classification of hilar cholangiocarcinoma and etiological diagnosis of low bile duct obstruction by US examination and DCUS examination was compared.Results:Compared with US,DCUS was more accurate in classification of hilar cholangiocarcinoma in 90 patients,P<0.05.Compared with US,DCUS was more accurate in the etiological diagnosis of low biliary tract obstruction in 90 patients(P<0.05).Conclusion:DCUS is more accurate in classification of hilar cholangiocarcinoma and etiological diagnosis of low bile duct obstruction in patients with obstructive jaundice.
