摘要
目的 探讨胰岛素瘤术前术中定位方法的诊断价值。方法 对 3 0例胰岛素瘤患者的术前B超、CT、MRI和选择性动脉造影 (DSA)检查的定位资料进行分析 ,统计了术中超声 (IOUS)、术中触诊、术中脾门静脉穿刺置管分段取血快速胰岛素测定 (PVS)三种方法对胰岛素瘤的定位准确率 ,并进行了比较研究。结果 超声、CT、MRI和DSA对胰岛素瘤的术前定位准确率分别为 3 0 .0 %、3 3 .3 %、41.7%、60 .0 % ,而IOUS ,术中触诊和术中PVS的定位准确率分别为 93 .3 %、80 .0 %和 92 .9%。结论 术中三种定位方法明显提高了胰岛素瘤的定位准确率 ,IOUS不但对胰岛素瘤的定位准确率高 ,而且可以清楚显示肿瘤与周围重要结构如主胰管、胆总管及血管的关系 ,帮助外科医生选择手术方法。
Objective To evaluate the value of intraoperative ultrasonography in localizing insulinomas.Methods Preoperative data were analysed in 30 cases of insulinomas examined by ultrasonography, computed tomography(CT), magnetic resonance imaging(MRI) and arteriography. The accurate rates of intraoperative localization with intraoperative ultrasound(IOUS), intraoperative palpation and intraoperative selective portal venous sampling(PVS) were reported and compared with each other. Results The preoperative accurate rates of localizing insulinoma by ultrasonography, CT, MRI and arteriography were 30.0%,33.3%,41.7% and 60.0%, respectively. The accurate rate of IOUS was 93.3%, of intraoperative palpation was 80.0%, of intraoperative PVS was 92.9%. Conclusion Intraoperative ultrasound not only shows the location of insulinoma accurately, but also provides the spatial relationship between tumour and vital structures, such as pancreatic duct, common bile duct, and critical blood vessels. It can thereby help surgeons choose appropriate surgical procedures and reduce the incidence of operative complications.
