摘　　要：目的探讨术中定位诊断在胰岛素瘤手术中的价值。方法回顾性分析经病理证实的126例胰岛素瘤的临床资料。结果男∶女为1∶1.8。45～65岁患者占58.7%。肿瘤直径≤2 cm者占95.2%。术前B超定位率为11.9%,SCT平扫定位率为37.0%,SCT增强定位率为69.8%,MRI定位率为63.6%。术中B超定位率100.0%。术中扪诊质硬者占86.5%,质韧者9.5%,质软者4.0%。单发肿瘤中,位于胰头者占23.7%,胰颈14.4%,胰体21.2%,胰尾40.7%。结论增强SCT是较有效的术前定位方法;术中扪诊联合术中B超是定位胰岛素瘤最有效的方法。Objective To research the value of introperative localization of the patients with insulinoma. Methods The clinical data of 126 patients with insulinoma were analyzed retrospectively. Results The ratio of male to female was 1 ： 1.8.58.7% of the patients were in the age from 45 to 65. The diameter of 95.2% of tumors was less than 2 cm. The positive rate of localization diagnosis before operation ：transab- dominal ultrasound 11.9% ,SCT 37.0% ,Enhanced SCT 69.8% , MRI 63.6%. The positive rate of intraoperative ultrasound was 100.0%. 86.5% of tumors in intraoperative palpation were hard,9.5% were tenacious,4.0% were soft. For single tumors,23.7% of tumors were lo- cated in the head of pancreas, 14.4% in the neck ,21.2% in the body,40.7% in the tail. Conclusion Enhanced SCT is the more effective examination for localization before operation. Intraoperative palpation combined with intraoperative ultrasound is the most effective way for localization.
