【摘要】 目的　了解触诊与 B超法诊断甲肿的差异及其原因。方法　采用人口比例概率抽样法对贵州省 30个县的 12 0 0名 8～ 10岁小学生用触诊法和 B超法同时进行检查。结果　 8岁组 B超法肿大率显著高于触诊法 (P<0 .0 1) ,10岁组触诊法肿大率高于 B超法 ,差异接近显著 (P=0 .0 5 99) ;以 B超法为金标准 ,触诊法的灵敏度为 5 8.6 2 % ,漏诊率为 41.38% ;特异度 89.5 7% ,误诊率为 10 .40 % (10 1/ 96 8)。触诊法与 B超法一致率为83.5 8%。结论　甲状腺肿的检出以 B超法为准 ,触诊法漏诊率偏高 ;导致误差的主要原因来自触诊检查者诸多主观因素的影响更多还原

【Abstract】 Objective In order to explore the difference and its reason between palpation method and ultrasonic methods on diagnosing goiter.Methods Tweleve hundred pupils of 8 to 10 age groups from 30 counties of GUIZHOU province were sampled by PPS method, and their thyroids were examined by palpation method and ultrasonic method at the same time.Results The goiter rate by ultrasonic method was significantly higher (P<0.01) among 8 age group ,and was nearly significantly lower (P=0.0599)among 10 age group than that by palpation method .With the use of ultrasonic as the gold standard of diagnosing goiter, the sensitivity, by palpation method, was 58.62%, the false negative rate was 41.38%, the specificity was 89.57%,and the false positive rate was 10.40% .The agreement rate was 83.58% between ultrasonic and palpation methods.Conclusions With ultrasonic as the gold standard, the false negative rate of palpation method was getting a bit high to diagnose goiter .The main reason causing the difference between palpation and ultrasonic method was the subjective factors from examiner of palpation.更多还原
