咽食管憩室与甲状腺结节在体检中的鉴别

目的探讨超声检查鉴别咽食管憩室（Zenker憩室）与甲状腺结节的价值。方法使用高频彩色超声探头，观察1219例受检者颈部包块在加压及侧卧位饮水后的大小、形态、内部回声及血流信号的变化。结果超声检查时探头加压后对比观察，Zenker憩室和甲状腺结节有图像变化者分别为5／7例和172／1212例，其图像变化率分别是71．43％和14．19％，二者比较差异有统计学意义（P〈0．05）。患者饮水后对比观察，Zenker憩室和甲状腺结节有变化者分别为7／7例和24／1212例，其图像变化率分别是100、00％和1．98％。二者比较差异有统计学意义，（P〈0、05）。Zenker憩室和甲状腺结节的检出率分别是0．098％和17．042％。结论超声检查对Zenker憩室与甲状腺结节具有一定的鉴别诊断价值，可以作为健康体检中Zenker憩室与甲状腺结节普查和定期复查的一种简便方法。

Ultrasonography in differentiation of Zenker diverticulum and thyroid nodule

Objective To assess the value of ultrasonography in distinguishing pharyngoesophageal diverticulum from thyroid nodule. Methods High-frequency sonography was used to detect the size, shape, echo and blood flow of cervix masses in 1219 patients in a lateral decubitus position after drinking water. Results On enhanced power, the image changing rates of pharyngoesophageal diverticulum and thyroid nodule were 71.43% and 14.19% respectively, and their difference was statistically significant（ P 〈 0.05 ）. On drinking water, the image change rates of pharyngoesophageal diverticulum and thyroid nodule were 100.00% and 1.98% respectively, and their difference was statistically significant （ P 〈 0.05 ）. The detection rates for pharyngoesophageal diverticulum and thyroid nodule were 0. 098% and 17. 042% respectively. Conclusions Ultrasound examination is of value in distinguishing pharyngoesophageal diverticulum from thyroid nodule in general health check up and regular health examination.
