胰岛素瘤的术前及术中超声定位

目的:探讨术前及术中超声在胰岛素瘤定位诊断中的价值.方法:对4例胰岛素瘤患者的术前B型超声检查B超及术中B超、计算机断层摄影(CT)、核磁共振成像术(MRI)和数字减影血管造影(DSA)定位治疗进行分析.结果:术前B超,CT,MRI和DSA对胰岛素瘤的定位诊断准确率分别为40%,100%,40%,20%和60%,术中超声(IOUS)定位诊断准确率为100%.结论:术中超声对胰岛素瘤的定位诊断率高,并可显示肿瘤的毗邻关系.有助于术中选择合适的手术方式.

Contribution of preoperative and intraoperative ultrasonographic localization of insulinomas

AIM:To evaluate the contribution of preo- perative and intraoperative ultrasonographic localization of insulinomas. METHODS:Preoperative data from four cases of insulinoma were analyzed using B ultrasonog- raphy,computed tomography(CT),magnetic resonance imaging(MRI)and digital subtraction angiography(DSA). RESULTS:The rates for accurately localizing insulinoma preoperatively by B ultrasonogra- phy,CT,MRI,and DSA were 40%,100%,40%, 20%,and 60%,respectively,and intraoperatively ultrasonography was 100%. CONCLUSION:Intraoperative ultrasound not only accurately shows the location of insuli- noma,but also the spatial relationship between insulinomas,thereby helping surgeons choose appropriate surgical procedures.
