目的:探讨高频超声对Zenker憩室(咽食管憩室)的诊断价值.方法:分析应用高频超声检测诊断的15例Zenker憩室患者,总结其超声表现,并与上消化道钡餐造影及术后病理结果进行对照.结果:在15例患者中4例病灶行上消化道钡餐确诊,11例病灶经术后病理确诊.15例Zenker憩室患者全部位于甲状腺左叶背侧,有3种声像图表现:①等回声病灶,内见点片状无回声,形态呈半圆状;②低回声病灶,形态不规则或半环状,边界清晰,内可见点状强回声;③强回声病灶,探头轻压后强回声可移动并伴有形态改变,周边隐约可见纤薄半环状低回声壁.结论:高频超声检查Zenker憩室具有方便、快捷和无创的优势,掌握其声像图特点及探查方法,有助于疾病的早期发现,避免误诊和漏诊,具有重要的临床价值.%Objective:To explore the diagnostic value of high-frequency ultrasound for Zenker diverticulum.Methods: 15 patients who were suspected as Zenker diverticulum through the diagnosis of using high frequency ultrasound were analyzed in the research. Their appearances of ultrasound were summarized, and these results were compared with barium meal at upper gastrointestinal tract and results of postoperative pathology, respectively.Results: In 15 patients, 4 cases were confirmed by adopting barium meal at upper gastrointestinal tract, and 11 cases were confirmed by adopting postoperative pathology. All of lesions in 15 cases were located on the back of left side of the thyroid gland, and there were 3 kinds of sonographic appearance. The first kind was equal echo lesion, and there were spots and schistoses without echo inside lesion, their form showed a semicircle shape. The second kind was hypoechoic, the form showed irregularity or semi cyclic annular, and the border was clear, and there were strong echogenic spots. The third kind was hyperechoic lesions, and the strong echo were movable with morphological changing after the slight pressure of search unit, and slim half ring low echo wall can be seen indistinctly around lesions.Conclusion:High-frequency ultrasonography is a convenient, rapid and non-invasive method for the diagnosis of Zenker diverticulum, and it is helpful to grasp its ultrasonogram characteristic and examination method in early detection of disease, avoiding misdiagnosis and missed diagnosis. Therefore, it has important clinical value.
