摘要
目的分析宫颈癌前病变中经阴道能量多普勒超声诊断的临床价值。方法选取44例疑似宫颈癌前病变患者作为B组,选取同期44例健康体检者作为A组。两组均经阴道能量多普勒超声检查, B组患者之后行阴道镜病理切片检查。以阴道镜病理切片检查结果为金标准,分析B组患者的经阴道能量多普勒超声诊断结果。比较两组能量多普勒血流特征[收缩期峰值血流速度(PSV)、阻力指数(RI)]以及血流信号分级情况。结果阴道镜病理切片检查结果显示:癌前病变20例,早期宫颈癌21例,宫颈炎症2例,宫颈肌瘤1例。经阴道能量多普勒超声检查结果显示,癌前病变和早期宫颈癌各22例。以阴道镜病理切片检查结果为金标准,经阴道能量多普勒超声检查的诊断符合率为93.18%,误诊率为6.82%。B组患者的PSV(13.57±4.39)cm/s快于A组的(8.42±2.51)cm/s, RI(0.49±0.13)低于A组的(0.72±0.06),差异具有统计学意义(P<0.05)。B组血流信号0、Ⅰ级比例分别为0、4.55%,均低于A组的79.55%、20.45%,差异均具有统计学意义(P<0.05);B组血流信号Ⅱ、Ⅲ级比例分别为27.27%、68.18%,均高于A组的0、0,差异均具有统计学意义(P<0.05)。结论在宫颈癌前病变中经阴道能量多普勒超声诊断,准确率高,子宫内局部病变血流分布更加直观清晰,为宫颈癌前病变临床诊断奠定了良好的基础。
Objective To analyze the clinical value of transvaginal color Doppler energy in diagnosis of cervical precancerous lesions. Methods There were 44 patients with suspected cervical precancerous lesions selected as group B, and 44 healthy persons as group A. Both groups were examined by transvaginal color Doppler energy, and group B still underwent colposcopy and skin biopsy examination. The diagnostic results of transvaginal color Doppler energy in group B was analyzed with colposcopy and skin biopsy examination as the gold standard. The energy Doppler flow characteristics [peak systolic velocity(PSV), resistance index(RI)], and blood flow signal grading of the two groups were compared. Results Colposcopy and skin biopsy examination showed that there were 20 cases of precancerous lesions, 21 cases of early cervical cancer, 2 cases of cervicitis and 1 case of cervical myoma. Transvaginal color Doppler energy showed that there were 22 cases of precancerous lesions and 22 cases of early cervical cancer. With colposcopy and skin biopsy examination as the gold standard, the coincidence rate of transvaginal color Doppler energy was 93.18%, and the misdiagnosis rate was 6.82%. PSV(13.57±4.39) cm/s of group B was higher than that of group A(8.42±2.51)cm/s, and RI(0.49±0.13) was lower than that of group A(0.72±0.06). The difference was statistically significant(P<0.05). The proportion of grade 0 and grade Ⅰ blood flow signals in group B was 0 and 4.55% respectively, which were lower than 79.55% and 20.45% in group A. The proportion of grade Ⅱ and grade Ⅲ blood flow signals in group B was 27.27% and 68.18% respectively, which were higher than 0 and 0 in group A. The difference was statistically significant(P<0.05). Conclusion The diagnosis of cervical precancerous lesions by transvaginal color Doppler energy is of high accuracy, and the distribution of blood flow in uterine lesions is more direct and clear. It lays a good foundation for clinical diagnosis of cervical precancerous lesions.
