摘要
目的:探讨超声等方法对胰岛素瘤的定位诊断价值。材料和方法:对42例经过手术和病理证实的胰岛素瘤患者术前定位诊断的各种方法进行回顾性分析,并与其他诊断方法对比分析其各自的定位符合率。结果:定位诊断符合率分别为B超31%(13/42)、EUS55.6%(5/9)、IOUS100%(10/10)、超声引导下PTPC100%(3/3)、CT59.5%(25/42)、MRI50%(6/12)、选择性DSA27.3%(3/11)及ASVS90%(9/10)。彩超(CDUS)对胰岛素瘤良、恶性有鉴别作用。结论:遵循循序渐进原则,先后选用B超(含CDUS)、EUS、CT等已可解决80%以上的定位诊断,然后再做MRI及ASVS;对仍未作出定位者,只要定性诊断明确即有手术探查指征,因为IOUS能提供可靠的定位信息。
To compare all the location methods, including B type ultrasonography （US）, color Doppler ultrasonography（CDUS）, endoscopic ultrasonography（EUS）, et al, in order to improve diagnosis value before surgery. Materials and Methods： To retrospective analyze of the diagnosis value of location methods before surgery in 42 patients with insulinoma of the pancreas, which were confirmed by surgery and pathology. Results： The diagnosis accordance rate of US was 31% （13/42）, EUS 55.6% （5/9）, IOUS 100% （10/10）, CT 59.5% （25/42）, MRI 50% （6/12）, DSA 27.3% （3/11）, PTPC 100% （3/3）, and selective intra- arterial calcium- stimulated hepatic venous sampling（ASVS） 90% （9/ 10）, respectively. Conclusion： If we comply with step by step principle in choosing location methods, including US, CDUS , EUS and CT, we may solve more than 80 percent problems in location. Then we can choose MRI and ASVS. If the accurate location of insulinoma could not be made before surgery, IOUS might provide exact potential information in the operation.
