目的 提高对非功能性胰岛细胞瘤的认识和诊断水平。方法 对 2 0例非功能性胰岛细胞瘤病例进行回顾性总结。结果 非功能性胰岛细胞瘤临床表现无特异性 ,超声等影像学检查检出率高 ,但特异性诊断正确率低 ,彩色多普勒超声检查显示 83 .3 %的瘤体血供丰富 ;病理检查恶性胰岛细胞瘤的比例达 75 .0 % ,免疫组织化学染色检测显示非功能性胰岛细胞瘤大多具有分泌功能。结论 提高对非功能性胰岛细胞瘤的声像图及病理方面的认识是术前作出正确诊断的关键
Objective To improve the understanding and diagnosis of non-functioning islet cell tumors. Methods A retrospective review of 20 non-functional islet cell tumors was performed. Results The non-functional islet cell tumor had no specific clinical manifestation. The detection rate of ultrasound and other imaging examinations was high, but the specific diagnostic accuracy was low. The color Doppler ultrasound examination showed that 83. 3% of tumors had abundant blood supply; The proportion of malignant islet cell tumors was up to 75.0 %. Immunohistochemical staining showed that most non-functioning islet cell tumors had secretory function. Conclusion Raising the awareness of non-functional pancreatic islet cell tumors in terms of sonography and pathology is the key to correct diagnosis before surgery
