咽食管憩室的超声诊断学特征分析

Ultrasonic diagnostic characteristics of pharyngo-esophageal diverticulum

目的探讨咽食管憩室(PED)的超声诊断学特征。方法回顾性分析2016年4月至2021年2月空军特色医学中心诊断的6例PED患者的超声图像资料,总结PED超声诊断学特征的直接征象与间接征象。结果6例患者中诊断准确4例,误诊为甲状腺结节2例,PED超声直接征象为突向甲状腺实质的"类结节"样回声,周缘呈低回声的"黏膜壁"结构,并与食管黏膜相延续,内含点状或线状气体强回声。间接征象为:病灶可随吞咽动作移动,饮水后病灶内"气液线"流动,加压探头后病灶不产生形变。结论根据PED在超声下的直接征象和间接征象,可更好地对PED进行辅助诊断,减少误诊的发生。

Objective To investigate the ultrasonic diagnostic characteristics of pharyngo-esophageal diverticulum(PED).MethodsThe ultrasonographic features of 6 cases with PED in Air Force Medical Center were analyzed retrospectively from April 2016 to February 2021.The direct and indirect signs of ultrasonic diagnostic characteristics of PED were summarized.ResultsAmong the 6 patients,4 cases were accurately diagnosed,2 cases were misdiagnosed as thyroid nodule.The direct ultrasonic signs were"nodular like"echo protruding to the thyroid parenchyma,low echo"mucosal wall"structure,and with the esophageal mucosa,containing strong echo of punctated or liner gas.The indirect signs were that the lesion could move with swallowing,the"gas-liquid line"in the lesion flowed after drinking water,and the lesion did not deform after pressure probe.ConclusionAccording to the direct and indirect ultrasonographic signs of PED,the auxiliary diagnosis of PED can be optimized and the incidence of misdiagnosis can be reduced.
