22例初诊为胰岛B细胞瘤患者的临床资料分析

目的 探讨胰岛B细胞瘤的定性诊断.方法 回顾性分析22例入院时诊断为胰岛B细胞瘤患者的临床资料,并根据临床最后诊断,将其分为胰岛B细胞瘤组(16例)和反应性低血糖组(6例),并详细比较有关指标.结果 饥饿/冷汗、昏迷、Whipple三联征、饥饿试验、空腹静脉血胰岛素(IRI)与血糖(G)的比值(I/G)大于0.3,两组上述指标比较差异均有统计学意义(P＜0.05),而发作时血糖数值、精神症状等两组比较差异均无统计学意义.结论 初诊时的临床资料可早期发现该病,尤其是Whipple三联征、饥饿试验、I/G＞0.3等指标在初诊时价值最大.

Objective To study and evaluate islet cell adenoma of preliminary diagnosis.Method Retrospective analysis Wag done on 22 patients clinical data of preliminarily diagnosed islet cell adenoma.They were divided into two groups according to final diagnosis,group of islet cell adenoma(n=16)and group of reacfional hypoglycemia n=6).Results There were significant differences between the two groups in term of fames,cold sweat,cataphora,Whipple triad,hungry test,the ratio offasting blood insulin and fasting blood glucose exceeding 0.3 (I/G＞0.3) (P＜0.05).No statistical differences were found on blood glucose level in hypoglycemia onset,psychiatric symptom.Conclusion The clinic data is helpful for preliminary diagnosis,and Whipple triad,hungry test,I/G＞0.3 above all.
