摘 要：目的 与传统影像学检查方法比较，评价内镜超声(EUS)在胰腺内分泌肿瘤——胰岛素瘤术前定位诊断中的临床价值。方法 6例临床疑为胰岛素瘤的患者术前行内镜超声、腹部超声(US)以及计算机断层扫描(CT)检查，同时与手术中的发现及手术后的病理结果相对比。结果 手术共发现胰腺占位病灶7个，术前EUS、CT、US对6例患者胰腺占位病灶的检出率分别为85.7%(6/7)、57.1%(4/7)和14.3%(1/7)；而与手术后病理结果比较，EUS对胰岛素瘤的诊断符合率为83.3%(5/6)；但对胰腺病灶的部位以及大小的诊断均基本与手术发现相符。结论 EUS对胰腺占位病灶的术前定位诊断优于传统的影像学检查，是一种临床可行且较有价值的检查方法。

Abstract：Objective To assess the clinical diagnostic value of endoscopic ultrasonography (EUS) in preoperative localization of pancreatic endocrine neoplasm——insulinoma by comparing with the conventional imaging procedures. Methods Six patients with insulinoma diagnosed by clinical and laboratory findings were assessed with US, CT and EUS to detect the pancreatic lesions before surgical intervention. All the cases then received laporatomy and tumors were examined by histological study. Results In six cases, seven lesions were found in pancreas by surgical procedures, the diagnostic detectability of pancreatic neoplasms by US, CT and EUS being 14.3% (1/7), 57.1% (4/7) and 85.7% (6/7) respectively. The diagnostic accuracy of insulinoma by EUS was 83.3% (5/6) as compared with histological study. However, the diagnostic detectability of site and size of pancreatic lesions by EUS was in accordance with that of surgical results. Conclusions EUS is superior to conventional image examinations in preoperative localization of pancreatic neoplasma and is a feasible and effective procedure in clinical diagnosis of insulinoma.
