摘要: 目的分析超声和CT检查对胆囊腺肌增生症的诊断价值。方法回顾性分析广州医科大学附属第二医院28例经病理证实的胆囊腺肌增生症患者超声和CT表现,分析其影像学特点,并以病理诊断为金标准,分析两种影像方法对胆囊腺肌增生症的诊断价值。率的比较采用χ2检验,P<0.05为差异有统计学意义;率的多重比较采用卡方分割,P<0.0125为差异具有统计学意义。结果 28例患者中,术前超声诊断胆囊腺肌增生症15例,CT诊断9例,CT诊断率为32.14%,超声诊断率为53.57%,χ2检验表明,超声与CT对胆囊腺肌症的诊断率差异无统计学意义(χ2=2.63,P=0.10);卡方分割分析CT及超声诊断不同类型胆囊腺肌症准确率的差异,结果表明,超声与CT对各种类型胆囊腺肌症的诊断率差异均无统计学意义(节段型:χ2=0,P=0.11;弥漫型:χ2=2.57,P=1.00;局灶型:χ2=1.42,P=0.23)。结论 CT及超声是诊断胆囊腺肌增生症的重要影像学方法;凸阵探头与线阵探头联合应用,可能提高超声对胆囊腺肌增生症的检出率。

Abstract: Objective To analyze the diagnostic values of ultrasonography and computed tomography ( CT) for gallbladder adenomyomatosis.Methods The ultrasound and CT findings of 28 cases of pathologically confirmed gallbladder adenomyomatosis in our hospital were retrospectively analyzed. The diagnostic values of the two imaging tools for gallbladder adenomyomatosis were analyzed with the pathological diagnosis as the gold standard. Comparison of rates was made by chi- square test; multiple comparisons of rates were made by partition of chi- square. Results Before operation, among the 28 patients, 15 were diagnosed with gallbladder adenomyomatosis by ultrasonography, and 9 were diagnosed by CT; the diagnostic rate of CT was 32. 14%, and the diagnostic rate of ultrasonography was 53. 57%. The chi- square test showed no difference between the diagnostic rates of ultrasonography and CT for gallbladder adenomyomatosis ( χ2=2. 63, P = 0. 10 >0. 05) . In addition, the statistical results showed no differences between the diagnostic rates of ultrasonography and CT for various types of gallbladder adenomyomatosis ( segmental type: χ2=0, P=0. 11 >0. 0125; diffuse type: χ2=2. 57, P =1. 00 > 0. 0125; focal type: χ2= 1. 42, P = 0. 23 > 0. 0125) . Conclusion CT and ultrasonography are two important imaging methods for the diagnosis of gallbladder adenomyomatosis. The detection rate of gallbladder adenomyomatosis can be increased through the combination of convex array probe and linear array probe in ultrasonography.-
