摘要
目的探讨经腹超声造影及超声内镜两种方法联合对胰岛素瘤的术前定位的准确性。方法 44例明确诊断为胰岛素瘤的患者在我院进行胰岛素瘤术前定位,其中包括CT平扫加增强、超声造影、内镜超声,对比分析经腹超声造影及内镜超声联合应用与增强CT在胰岛素瘤定位诊断的准确性。结果 44例胰岛素瘤均经外科手术治疗;41例患者进行了术前CT平扫及增强CT检查,其中23例患者的肿瘤定位准确,准确率为56.1%,33例患者联合超声造影与内镜超声定位,30例患者定位准确(90.9%),联合超声造影与内镜超声的定位准确性与CT平扫加增强定位准确性存在统计学差异(P<0.05)。结论与CT平扫加增强比较,联合应用超声造影及内镜超声两种方法可以显著提高胰岛细胞瘤定位诊断的准确性,值得在临床上进一步推广应用。
Objective To explore the accuracy of the combined approach of the contrast-enhanced ultrasonography（ C, EUS）and endoscopic ultrasound （EUS）in preoperative detection of insulinoma. Methods Forty- four instances with clinical and biochemical signs of pancreatic insulinoma underwent CT, EUS and CEUS. The accuracy of preoperative diagnoses location of the lesions were evaluated and compared between the combined approach of CEUS and EUS and CT. Results Of the 44 patients treated surgically,41 had CT with successful localization in 23 （56. 1% ） by CT, Thirty three had the combined approach of CEUS and EUS. Thirty patients （90. 9% ）was localized successful. The analysis showed that the accuracy had a significant difference between the combined aptm）ach and CT（ P 〈 0. 05）. Conclusions The sensitivity and the accuracy of CEUS and EUS are better than CT in preoperative detection of pancreatic insulinoma.
