超声造影与常规超声对胆囊息肉样病变鉴别诊断价值的对比分析

Comparison of contrast-enhanced ultrasonography and conventional ultrasonography in diagnosis of polypoid lesions of gallbladder

目的比较超声造影(CEUS)与常规超声对胆囊息肉样病变(PLG)的鉴别诊断价值。方法回顾性分析2009年2月至2013年11月哈尔滨医科大学第一附属医院经手术病理证实的49例PLG患者49个病灶常规超声及CEUS表现。包括胆囊癌7个,胆囊息肉24个,胆囊腺肌症14个,胆囊腺瘤4个。以手术病理结果作为金标准,分别计算常规超声、CEUS以及两者联合应用诊断PLG的敏感度、特异度及准确性。结果常规超声诊断PLG的敏感度、特异度、准确性分别为33.3%、74.3%、68.3%,CEUS诊断PLG的敏感度、特异度、准确性分别为66.7%、85.7%、82.9%,两者联合应用诊断PLG的敏感度、特异度、准确性分别为83.3%、88.6%、87.8%。结论 CEUS可提高PLG的诊断准确率,但必须以常规超声作为基础,两者相互结合可提高PLG的鉴别诊断能力。

ObjectiveTo compare the clinical value of contrast-enhanced ultrasonography （CEUS） and conventional ultrasonography in diagnosing polypoid lesion of gallbladder （PLG）.MethodsThe postoperative pathology and clinical manifestation of 49 PLG patients were retrospectively analyzed in the First Afifliated Hospital of Harbin Medical University. Of them, 7 cases were maligant lesions, 4 cases were adenomas, 24 cases were polyps of gallbladder and 14 cases were adenomyomatosis of gallbladder. With postoperative pathology as golden standard, the sensitivity, speciifcity and PLG speciifcity were calculatedfor conventional ultrasonography, CEUS and conventional ultrasonography plus CEUS.ResultsThe sensitivity, specificity and PLG specificity were 33.3%, 74.3% and 68.3% for conventional ultrasonography, and 66.7%, 85.7% and 82.9% for CEUS respectively. The conventional ultrasonography plus CEUS were 83.3%, 88.6% and 87.8%.ConclusionCEUS could signiifcantly improve the diagnostic accuracy.
