对１５例非功能性胰岛细胞瘤进行回顾性分析，以探讨该病的诊断和治疗。钡餐、Ｂ超、ＣＴ、选择性腹腔动脉造影以及ＥＲＣＰ对该病有诊断价值。作者认为应将癌细胞异形性、核分裂相和瘤细胞侵犯被膜或血管作为诊断恶性的标准。手术切除是治疗非功能性胰岛细胞瘤的主要方法。１５例中单纯行肿瘤摘除术４例，胰体尾切除术８例，胰十二指肠切除术２例。手术切除率９３．３％（１４／１５），术后疗效满意 Fifteen non-functional islet cell tumors were retrospectively analyzed to investigate the diagnosis and treatment of the disease. Barium meal, B ultrasound, CT, selective celiac arteriography, and ERCP have diagnostic value for this disease. The authors believe that the heterogeneity of the cancer cells, the mitotic phase, and the invasion of tumor cells or blood vessels should be the criteria for the diagnosis of malignancy. Surgical resection is the main method of treating nonfunctional islet cell tumors. Among the 15 cases, 4 underwent tumor resection alone, 8 underwent pancreatic body resection and 2 underwent pancreaticoduodenectomy. The surgical resection rate was 93.3% (14/15), and the curative effect was satisfactory
