超声内镜在胰岛细胞瘤术前定位诊断中的价值

Value of endoscopic ultrasound in preoperative diagnosis of insulinoma

目的探讨超声内镜(endoscopic ultrasound,EUS)在胰岛细胞瘤(insulinoma)术前定位诊断中的价值。方法 2006-2012年我院51例经手术切除后病理确诊的胰岛细胞瘤患者,对其术前不同检查方法的影像学资料进行回顾性分析,探讨胰岛细胞瘤术前检查方法的选择。结果各检查方法术前定位的敏感性和准确性:EUS为97.9%和90.2%,经腹超声为20.7%和18.7%,超声造影为93.5%和78.4%,增强CT为57.1%和54.1%,增强MRI为89.5%和77.3%,血管造影为76.9%和71.4%。结论 EUS检查对胰岛细胞瘤的术前定位具有重要价值,安全可靠,可作为首选,如患者条件允许,可再选择超声造影和腹部增强MRI。

Objective To study the value of endoscopic ultrasound （EUS） in preoperative diagnosis of insulinoma. Methods Clinical and imaging data about 51 pathology-confirmed insulinoma patients admitted to our hospital from 2006 to 2012 were retrospectively analyzed. How to select the diagnostic methods of insulinoma was studied. Results The sensitivity and accuracy of EUS, TAUS, CEUS, CT, MRI and SAG were 97.9% and 90.2%, 20.7%and 18.7%, 93.5%and 78.4%, 57.1%and 54.1%, 89.5%and 77.3%, 76.9%and 71.4%, respectively. Conclusion EUS plays an important role in preoperative diagnosis of insulinoma. CEUS and MRI can also be used in preoperative diagnosis of insulinoma if the patients＆#39; condition permits.
