目的探讨超声对咽食管憩室的诊断价值。方法回顾性分析经手术或食管X线钡餐造影证实的14例咽食管憩室,总结其声像图特征。结果 14例病灶中3例位于甲状腺右叶后方,11例位于甲状腺左叶后方。14例憩室周边均可见半环状、声晕状低回声。2例憩室内仅见少许无回声;12例憩室回声不均质,内见点状或斑片状强回声,部分后方伴“彗星尾征”或声影。超声多切面扫查发现14例病灶中有10例与毗邻的食管壁相连续。饮水后观察,11例病灶内见液体流入,3例病灶内部回声变化不明显。结论憩室内点状或斑片状强回声,周边可见半环状、声晕状低回声与食管壁相连续,饮水后内部回声改变是咽食管憩室特征性超声表现,超声结合饮水试验多切面观察可提高其诊断准确度。
Objective To investigate the diagnostic value of ultrasound on pharyngeal esophageal diverticulum. Methods Retrospective analysis of 14 cases of pharyngoesophageal diverticula confirmed by surgery or esophageal X-ray barium meal angiography, and summarizes its sonographic features. Results Of the 14 lesions, 3 were located behind the right lobe of thyroid gland and 11 behind the left lobe of thyroid. 14 cases were seen around the diverticula half-ring, hypoechoic hypoechoic. 2 cases of diverticulitis only a few no echo; 12 cases of diverticulum echo is not homogeneous, see within the spot or patchy echo, part of the rear with “comet tail sign” or sound shadow. Ultrasound multi-section scan found in 14 cases of lesions in 10 cases and adjacent esophageal wall continuous. After drinking water observation, see 11 cases of fluid inflow within the lesion, three lesions within the echo was not obvious. Conclusions The punctate or patchy hyperechoic in the diverticulum can be seen in the periphery with semi-ring shape. The hypoechoic hypoechoic sound is continuous with the esophageal wall. The internal echo change after phacoemulsification is the characteristic ultrasound manifestation of the pharyngoesophageal diverticulum. Observation can improve the diagnostic accuracy.
