彩色多普勒超声诊断胆囊息肉样病变的临床价值

目的探讨彩色多普勒超声检查在胆囊息内样病变诊断的临床应用价值。方法对71例胆囊息内样病变的彩色多普勒超声表现与手术切除后的病理检查结果进行对照分析。结果胆囊腺瘤和胆囊癌病灶直径大于胆固醇性息内、炎性息内和腺肌样增生，如果以直径≥8mm为诊断指标，超声提示腺瘤和结节型胆囊癌的敏感性为87．7％，特畀性为81．5％。胆囊腺瘤和胆囊癌病灶内部血流较丰富，如果以PSV≥0．2m／s、RI≥0．65为诊断指标，超声提示腺瘤和胆囊癌的敏感性为90．1％，特异性为86．3％。结论彩色多普勒超声检查中病灶的大小结合血流动力学指标测定对胆囊息内样病变的诊断有重要价值。

Clinical values of color Doppler imaging for polypoid lesions of the gallbladder

Objective To explore the clinical value of color Doppler imaging （CDI） for polypoid lesions of the gallbladder. Methods The features of CDI and postoperative pathologic results about the polypoid lesions of the gallbladder in 71 patients were analyzed. Results The lesion diameter of adenoma and gallbladder carcinoma was larger than cholesterol polyp, adenomyosis and phlogistic polyp. When the diameter of polyp lesions larger than 8mm was adopted as diagnostic criteria, the sensitivity and specificity of the ultrasound in diagnosis of adenoma and gallbladder carcinoma were 87. 7% and 81. 5%. When PSV≥0. 2m/s and RICO. 65 were adopted as diagnostic criteria, the sensitivity and specificity of the ultrasound in diagnosis of adenoma and gallbladder carcinoma were 90. 1% and 86.3%. Conclusion Color Doppler ultrasound is confirmed of great value in diagnosis of polypoid lesions of the gallbladder by analyzing the lesion diameter and CDI criteria.
