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。
Objective: To investigate the value of VCT enhanced scan combined with post-ERCP in the diagnosis of hilar cholangiocarcinoma. MATERIALS AND METHODS: Three phases of enhanced hilar cholangiocarcinoma and VCT scan images of 20 cases of hilar cholangiocarcinoma were analyzed. The original image was post-processed to determine the location and extent of tumor invasion, the invasion of hepatic vessels and the local lymph nodes And organ metastasis; the type and preoperative evaluation results and surgical results were analyzed. Results: Twenty patients underwent VCT three-phase enhanced scan and ERCP postoperative scan. The diagnosis was consistent with the pathological findings in 20 cases and the accuracy of localization was 16. Conclusion: The application of VCT combined with ERCP scan in the reconstruction of biliary system and revascularization can be used as an effective method for the diagnosis and preoperative evaluation of hilar cholangiocarcinoma.
