目的 :探讨非功能性胰岛细胞瘤的诊断和治疗方法。方法 :对 1968～ 1998年间收治的非功能性胰岛细胞瘤 2 2例临床资料进行回顾性分析。结果 :2 2例患者 ,68.2 %的病人发现上腹部肿块或查体发现胰腺肿块 ,B超和CT检查肿块定位准确率分别为 80 %和 87 5%。肿瘤钙化率和强化率分别为4 3 8%和 83 3%。术前超声引导肿块穿刺活检 9例 ,8例 ( 88 9% )能定性诊断。结论 :B超、CT和术前超声引导肿块穿刺活检是发现本病的主要手段 ,应将病理检查和肿瘤生物学行为结合起来判定良恶性 ,手术切除是治疗本病的有效方式
Objective: To investigate the diagnosis and treatment of non-functional islet cell tumor. Methods: The clinical data of 22 patients with non-functional islet cell tumor treated from 1968 to 1998 were analyzed retrospectively. Results: Twenty-two patients, 68.2% of patients found that the abdominal mass or examination revealed pancreatic mass, B ultrasound and CT examination mass positioning accuracy was 80% and 87 5%. Tumor calcification rate and enhancement rate were 43.8% and 83.3%, respectively. Preoperative ultrasound guided mass biopsy in 9 cases, 8 cases (88 9%) can be qualitative diagnosis. Conclusion: B-ultrasound, CT and preoperative ultrasound-guided mass biopsy are the main means to detect this disease. Pathological examination and tumor biological behavior should be combined to determine the benign and malignant. Surgical resection is an effective way to treat this disease
