VCT三期增强结合ERCP后扫描诊断肝门胆管癌的价值

The Value of Volume CT Three-Phase Contrast-Enhanced Scanning Combined with ERCP Postoperative Scanning in the Diagnosis of Hilar Cholangiocarcinoma

目的:探讨VCT增强扫描结合ERCP后扫描在肝门胆管癌诊断中的价值。材料和方法:分析20例肝门胆管癌三期增强扫描及ERCP术后VCT扫描图像,并对原始图像进行后处理,判断肿瘤的部位和侵及范围,肝门部血管受侵情况,局部淋巴结及脏器转移情况;将分型及术前评估结果与手术结果进行对照分析。结果:20例患者均行VCT三期增强扫描及ERCP术后扫描,诊断与病理结果一致20例,定位分型准确16例。结论:应用VCT三期增强结合ERCP后扫描行胆系及血管重建可作为肝门胆管癌诊断及术前评估的有效方法。

Purpose To explore the value of volume CT （VCT） three-phase contrast-enhanced scanning combined with ERCP postoperative scanning in the diagnosis of hilar cholangiocarcinoma. Materials and Methods Twenty patients with hilar cholangiocarcinoma underwent both three-phase contrast-enhanced scanning and ER- CP postoperative scanning by 64-row VCT. All the images were reconstructed with the workstation. The location and extension of tumor, range of invasion of the hepatic artery, portal vein, and bile duct, and metastasis of lymph node and liver were observed. The results of Bismuth classification and preoperative evaluation were compared with those after surgical exploration. Results The diagnosis of VCT was consistent with pathology in 20 cases. The results of preoperative Bismuth classification were consistent with those of surgical exploration in 16 of 20 patients. Conclusions The combination of three-phase contrast-enhanced scanning and ERCP postoperative scanning with VCT image reconstruction is a valuable method in the diagnosis and preoperative evaluation of hilar cholangiocarcinoma.
