目的应用B超对杭州、临潼两地健康体检人群甲状腺结节的检查结果进行比较分析。方法回顾性分析2008年1月-2012年12月在空军杭州及临潼航空医学鉴定训练中心体检的27 196例、18 362例健康人的甲状腺超声检查结果,按不同年份比较两地甲状腺结节性疾病的检出率、各年动态变化情况及男女发病比例,并比较两地5028例和3893例甲状腺结节性疾病中甲状腺囊肿、结节性甲状腺肿、甲状腺腺瘤、甲状腺癌等病变的构成差异。结果杭州及临潼两体检中心检出的甲状腺结节性疾病检出率逐年升高(P<0.05),杭州中心各年B超检出率均高于临潼中心(P<0.05),且女性检出率高于男性(P<0.01)。两中心甲状腺囊肿检出率比较差异无统计学意义(P>0.05),结节性甲状腺肿、甲状腺腺瘤、甲状腺癌两中心各组数据组间比较差异均有统计学意义(P<0.05)。结论近5年内两中心甲状腺结节发生率逐年升高且女性高发于男性,两中心甲状腺结节性病变的疾病构成比差异较大,揭示B超在健康体检中对甲状腺结节的检查具有重要价值。
Objective To compare and analyze the examination results of thyroid nodules among healthy physical examination population in Hangzhou and Lintong by B-ultrasound. Methods A retrospective analysis was made on the thyroid ultrasound findings of 27 196 and 18 362 healthy people who were examined at Air Force Hangzhou and Lintong Aviation Medical Appraisal Training Centers from January 2008 to December 2012. The thyroid nodules The detection rate of disease, the dynamic changes of each year and the incidence of male and female patients, and compared the constitution of thyroid cyst, nodular goiter, thyroid adenoma and thyroid cancer in 5028 cases and 3893 thyroid nodular diseases in both places difference. Results The detection rates of thyroid nodular diseases in Hangzhou and Lintong medical centers increased year by year (P <0.05). The detection rates of B-ultrasound in Hangzhou center were higher than those in Lintong center (P <0.05) Out rate was higher than males (P <0.01). There was no significant difference in the detection rate of thyroid cyst between the two centers (P> 0.05). There was significant difference between the data sets of two groups (nodular goiter, thyroid adenoma and thyroid cancer) (P <0.05) . Conclusion The incidence of thyroid nodules in two centers increased year by year in recent five years and the incidence of thyroid nodules was higher in males. The difference in the proportions of the diseases in thyroid nodules between the two centers is quite different. It is of great importance to examine thyroid nodules in healthy subjects value.
