【摘要】：目的:采用Meta分析的方法評價超聲造影與增強CT鑒別腎臟囊性病變良惡性的診斷價值。方法:制定納入標準和排除標準,通過計算機檢索PubMed、cochrane圖書館、Embase、中國知網、萬方數(shù)據服務平臺等數(shù)據庫,采用主題詞和自由詞相結合、手工檢索和網絡檢索相結合的檢索方式,且對納入文獻的參考文獻均進行二次檢索。檢索詞包括超聲造影、增強CT、腎囊性病變等,檢索時限均從建庫至2016年12月,搜集超聲造影與增強CT對腎臟囊性病變的診斷性試驗的中英文文獻。依據納入標準和排除標準,由2位評價者獨立篩選出符合標準的相關文獻、提取資料并用診斷性試驗準確性質量評價工具QUADAS評價文獻質量,使用Meta-Disc1.4軟件,對納入文獻的數(shù)據進行異質性檢驗和閾值效應分析,分別計算出超聲造影與增強CT診斷腎臟囊性病變的合并敏感度、特異度、陽性似然比、陰性似然比及診斷比值比,分別繪制兩種檢查的綜合受試者工作特征曲線(SROC),通過二者的曲線下面積評估CEUS與增強CT對腎囊性病變的診斷價值。結果:共納入8個診斷性試驗,包含364個病灶。Meta分析統(tǒng)計結果為,超聲造影診斷腎囊性腫瘤的合并敏感度、特異度、陽性似然比、陰性似然比、診斷比值比分別為0.96[95%CI(0.92,0.98)]、0.77[95%CI(0.70,0.83)]、3.69[95%CI(2.87,4.76)]、0.07[95%CI(0.04,0.14)]和54.88[95%CI(25.48,118.24)]。而增強CT依次為0.84[95%CI(0.78,0.89)]、0.81[95%CI(0.75,0.87)]、4.12[95%CI(3.06,5.55)]、0.22[95%CI(0.10,0.45)]和20.74[95%CI(11.44,35.24)]。兩者SROC曲線下面積分別為0.9173和0.8634。結論:超聲造影較增強CT對腎囊性腫瘤具有較好的診斷價值。并且CEUS對囊性腎癌的檢出具有更高的靈敏度,不易遺漏惡性病變。
[Abstract]:Objective: to evaluate the diagnostic value of contrast-enhanced CT and contrast-enhanced CT in the diagnosis of benign and malignant renal cystic lesions by Meta analysis. The database, such as Wanfang data service platform, adopts the combination of subject words and free words, the combination of manual retrieval and network retrieval, and the second retrieval of the references that are included in the literature. The key words include contrast-enhanced ultrasound, The search time of enhanced CT, renal cystic lesions, etc., from the establishment of the library to December 2016, collected the Chinese and English literature on the diagnostic test of renal cystic lesions by contrast-enhanced CT and contrast-enhanced CT, according to the inclusive criteria and exclusion criteria, Two evaluators independently sifted out relevant documents that met the criteria, extracted the data and evaluated the literature quality with diagnostic test accuracy evaluation tool QUADAS, and used Meta-Disc1.4 software to evaluate the literature quality. The combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic ratio ratio of contrast-enhanced CT and contrast-enhanced CT in the diagnosis of renal cystic lesions were calculated by heterogeneity test and threshold effect analysis. The operating characteristic curves of two kinds of integrated subjects were drawn, and the diagnostic value of CEUS and enhanced CT in renal cysts was evaluated by the area under the curves. Results: eight diagnostic tests were included. The combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio of contrast-enhanced ultrasonography in the diagnosis of renal cystic tumors were analyzed. The diagnostic ratios were 0.96 [95CI0.92 0.98)] 0.77 [95CI0.700.83)] 3.69 [95CI2.874.76)] 0.07 [95CII 0.040.14)] and 54.88 [95CI25.48118.24]. The area under the curve of enhanced CT was 0.84 [95CI0.780.89)] 0.81 [95CI0.750.870.87] 4.12 [95CI3.060.55)] 0.22 [95CI11.44.4545] and 20.74 [11.4442435.The area under the curve was 0.9173 and 860.344.Conclusion: enhanced CT is better than enhanced CT in the diagnosis of renal cell carcinoma and CEUS. Has higher sensitivity, It is not easy to omit malignant lesions.
