胰腺癌的可切除性评价(经动脉双期螺旋CT与血管造影的对比分析)

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造影及经动脉增强双期螺旋ＣＴ扫描，对胰腺癌的临床应用价值。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术，具有较高的临床应用价值。

Assessing the resectability of pancreatic cancer:comparision of dualphase helical CT with angiography

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.
