胰岛瘤的定位诊断附8例临床分析

目的分析胰岛瘤定位诊断的方法,探讨合理选用的策略。方法对1995年1月～2008年12月间我院收治的8例胰岛瘤病例的诊治进行回顾性分析。结果本组病例均行手术治疗,术中均发现肿瘤,包括2例定性诊断明确,但无定位诊断的病人。术前B超定位准确率37.5%,CT75.0%;术前CT检查与B超检查有显著性差异（P〈0.01）。结论胰岛瘤术前定位诊断有助于手术方式的选择。B超和CT均应为术前常规检查,胰岛瘤CT诊断阳性率较B超高。术前各种检查仍不能定位时,术中探查和B超是目前定位最好的方法。对定性诊断明确的病人,无论能否获得定位诊断,均应及早手术探查,以免延误治疗。

Localization of imsutinoma： clinical analysis of 8 cases

[Objective] To analyze the localization procedures of insulinoma and explore the strategy of reasonable selection. [Methods] A retrospective analysis was performed for 8 cases of insulinoma who received treatment from Jan. 1995 to Dec. 2008 in our Hospital. [Result] All patients underwent surgical treatment. The tumor was found in all the 8 patient s （including 2 without preoperative localization）. Old. The preoperative localization accuracy of B-ultrasonography （B-US） and computed tomography （CT） was 37.5%and 75.0% respectively; There was a sig- nificant difference between B-US and CT examinations （P〈0.01）. [Conclusion] Localization of insulinoma is useful forselecting surgical procedure. B-US and CT should be the routine preoperational imaging examination. CT of insuiinoma has a higher diagnostic rate than that of B-US. Exploration and IOUS are the best ways of localization. Following definite diagnosis, surgical exploration is nevertheless advised, though in some cases satisfied localization is difficult to achieve.
