摘　　要：目的:探讨各种影像学检查在胰岛素瘤定位诊断中的应用价值。方法:2007年6月至2008年7月我院收治35例胰岛素瘤患者,总结其临床特点并对比研究其影像学定位诊断方法。结果:B超检查准确率28.6%,CT检查准确率60.6%,MRI检查准确率69.2%,数字减影血管造影(digital subtraction angiography,DSA)检查准确率73.3%,内镜超声检查准确率70%,超声造影检查准确率73.9%,腹腔镜术中超声检查准确率87.8%。结论:在胰岛素瘤的微创治疗中,腹腔镜术中超声检查有利于发现和定位肿瘤,并确保手术安全顺利的实施。术前合理联合应用多种影像学方法有助于肿瘤的定位诊断。Objective： To evaluate the methods of imageology in identification and localization of pancreatic insulinomas. Methods：The clinical data of 35 patients with insulinoma underwent surgical treatment in our institution from Jun. 2007 to Jul. 2008 were reviewed retrospectively. The presenting symptoms, biochemical studies, preoperative and intraoperative localization studies were analyzed. Different methods of localization diagnosis in insulinomas were compared with each other. Results： The preoperative accurate rates of localizing insulinoma by uhrasonography, CT, MRI and arteriography were 28.6% ,60.6% ,69.2% and 73.3% respectively. The accurate rate of endoscopic ultrasound was 70%, and laparoscopic intraoperative ultrasound was 87.8%. Conclusions ：The laparoscopic intraoperative ultrasound is greatly helpful to identify the lesions and surgical procedures. The combination of different methods is an efficient approach in the localization diagnosis of insulinoma.
