摘要
目的 探讨彩色多普勒血流显像(CDFI)在胰头和壶腹周围癌可切除性评估中的应用价值。方法 应用CDFI检测21例胰头和壶腹周围癌患者,并与CT(增强)比较。根据肿瘤和相邻血管组织,即肠系膜上动脉(SMA)、肠系膜上静脉(SMV)和门静脉(PV)的关系,设计胰腺多普勒评分(PDS)为四个等级:1分、2分、3分和4分。结果 显示PDS评分1、2、3分者可以切除,证实符合率为95.2%,PDS评分为4分者不可切除,证实符合率为100%,总的准确率为97.8%,与CT(增强)相比,CDFI检测对胰头和壶腹周围癌可切除性评估的应用价值更高。
Objective To assess resectability of pancreatic head and periampullary tumors by color Doppler flow imaging.Methods Based on the relationship of tumor to the adjacent vascular structures:superior mesenteric artery(SMA),superior mesenteric vein(SMV),and portal vein(PV),pancreatic Doppler score(PDS) was defined as four graded,that is 1,2,3,and 4.Twenty one patients with pancreatic head or periampullary tumors were examined.The PDS was compared with enhanced CT scanning.Results Patients with PDS of 1,2,3 were resectable (postive predictive value 95.2 %).Patients with PDS of 4 had unrectable tumor (Postive predictive value 97.8 %).Color Doppler flow imaging was more accurate than enhanced CT scanning in assessement of resectability of pancreatic head and periampallary tumors.Conclusion It is an effective method to use color Doppler flow imaging to assess resctability of pancreatic head and periampullary tumor.
