CT增强扫描对胆囊息肉样病变的综合诊断价值分析

The value of CT enhanced scan in the comprehensive diagnosis of gallbladder polypoid lesions

目的分析CT增强扫描对胆囊息肉样病变的综合诊断价值。方法选取于2016年4月~2018年4月到本院接收的已经病理确诊的86例胆囊息肉样病变患者进行研究,术前均予以超声诊断及CT增强扫描,比较两种诊断方法的综合诊断价值。结果经病理学诊断,发现45例胆固醇息肉、10例胆囊腺瘤、10例胆囊腺肌症、9例胆囊炎症、12例慢性厚壁胆囊炎。超声诊断结果显示:胆固醇息肉确诊率为84.44%、误诊率为15.56%;胆囊腺瘤确诊率为60.00%、误诊率为40.00%;胆囊腺肌症确诊率100.00%;胆囊炎性确诊率为88.89%、误诊率为11.11%;慢性厚壁胆囊炎确诊量率为100.00%。CT增强诊断结果显示:胆固醇息肉确诊率为73.33%、误诊率为26.67%;胆囊腺瘤确诊率为80.00%、误诊率为20.00%;胆囊腺肌症确诊率为90.00%、误诊率为10.00%;胆囊炎性确诊率为77.78%、误诊率为22.22%;慢性厚壁胆囊炎确诊率为91.67%、误诊率为9.09%。结论对超声、CT增强扫描诊断胆囊息肉样病变的诊断效果均好,但CT增强扫描诊断肿瘤性息肉的效果显著优于超声,而超声诊断良性胆囊息肉样病变的效果现在显著优于CT增强扫描,二者可联合应用于胆囊息肉样病变的临床诊断中。

Objective To analyze the comprehensive diagnostic value of CT enhanced scan for polypoid lesions of the gallbladder.Methods 86 patients with polypoid lesions of gallbladder who had been pathologically diagnosed from April 2016 to April 2018 were selected and studied.All patients were diagnosed by ultrasonography and enhanced CT scan before operation.Results After pathological diagnosis,45 cases of cholesterol polyps,10 cases of gallbladder adenoma,10 cases of gallbladder adenomyosis,9 cases of gallbladder inflammation,and 12 cases of chronic thick-wall cholecystitis were found.Ultrasound diagnosis showed that the diagnosis rate of cholesterol polyps was 84.44%,the misdiagnosis rate was 15.56%;the diagnosis rate of gallbladder adenoma was 60.00%,the misdiagnosis rate was 40.00%;the diagnosis rate of gallbladder adenomyosis was 100.00%;the diagnosis rate of cholecystitis was 88.89%,misdiagnosis rate was 11.11%;the diagnosis rate of chronic thick-wall cholecystitis was 100.00%.CT enhanced diagnosis showed that the diagnosis rate of cholesterol polyps was 73.33%,the misdiagnosis rate was 26.67%;the diagnosis rate of gallbladder adenoma was 80.00%,the misdiagnosis rate was 20.00%;the diagnosis rate of gallbladder adenomyosis was 90.00%,and the misdiagnosis rate was 10.00%.The diagnosis rate of cholecystitis was 77.78%,the misdiagnosis rate was 22.22%;the diagnosis rate of chronic thick cholecystitis was 91.67%,and the misdiagnosis rate was 9.09%.Conclusion Both ultrasound and CT enhanced scan are effective in the diagnosis of polypoid lesions of gallbladder,but the effect of CT enhanced scan for the diagnosis of neoplastic polyps is significantly better than ultrasound,and the effect of ultrasound diagnosis of benign gallbladder polypoid lesions is now significantly better than CT enhancement.The two can be used in the clinical diagnosis of gallbladder polypoid lesions.
