摘要
目的分别采用经动脉双期螺旋ＣＴ扫描和选择性血管造影，对胰腺癌的可切除性进行术前前瞻性评价，以确定各自的临床应用价值。方法对１５例胰腺癌术前均行选择性血管造影及经动脉增强双期螺旋ＣＴ扫描，对胰腺癌的可切除性分别进行评价，两者对比，以手术及病理结果作为标准，评价经动脉双期螺旋ＣＴ扫描的临床应用价值。结果１５例胰腺癌，经手术探查和病理诊断，２例可根治切除，１３例不可根治切除。对２例可根治切除者，ＣＴ和血管造影均作出了正确诊断；对１３例不可根治切除者，ＣＴ诊断出１２例，而血管造影只正确判定出９例。在评价胰周主要血管受累方面，螺旋ＣＴ亦优于血管造影。结论经动脉双期螺旋ＣＴ扫描弥补了血管造影的不足，能够更为准确、全面地评价胰腺癌的可切除性，具有较高的临床应用价值。
Objective To evaluate the use of dualphase helical computed tomography (CT) in preoperative assessment of resectability of pancreatic cancer and to correlate the CT findings with angiographic,histopathologic and surgical findings. Methods Tumor resectability was prospectively evaluated in 15 patients with proven pancreatic adenocarcinoma. Both dualphase helical CT scanning (enhanced via arteries) and selective angiography were obtained in each patient for assessing tumor resectability (mainly peripancreatic vascular involvements). CT and angiographic results were correlated with surgical and histopathologic results. Results Thirteen of 15 patients had nonresectable disease. For the other two resectable cases,both helical CT and angiography were correct in assessing resectability. For the 13 nonresectable cases, helical CT correctly predicted 12 and angiography correctly predicted 9. In assessing vascular involvements, helical CT also showed superiority to angiography in some cases. Conclusions Dualphase helical CT is superior to angiography in assessing resectability in patients with pancreatic adenocarcinoma. The combination of the two modalities can further improve overall accuracy of assessment.
