目的探讨经阴道超声结合彩色多普勒超声检查对卵巢肿瘤良恶判断的价值。方法选取吉林省四平市妇婴医院收治的卵巢肿瘤患者60例作为研究对象,病理证实良性肿瘤46例、恶性肿瘤14例。分别进行阴道超声及彩色多普勒超声检查,分析良恶性肿瘤的形态特征及血流分布情况,测定肿块收缩期峰值流速(PSV)及阻力指数(RI)。进行肿瘤超声评分,判断肿瘤良、恶性,并与病理诊断对比。采用SPSS 17.0统计学软件进行数据处理,计量资料采用(xˉ±s)表示,组间比较采用七检验;数据资料以百分率表示组间比较采用χ2检验或Fisher确切据实率法检验,P≤0.05为差异有统计学意义。结果良性肿瘤超声诊断符合率为93.8%(46/49),恶性肿瘤超声符合率为78.6(11/14)。多普勒超声检查显示恶性肿瘤内部血管多分布于肿瘤实质区域,排列杂乱不规则,血流分型多为Ⅲ型;良性肿瘤血管多分布于周边或间隔上,血管排列规则、稀疏,血流分型多为I、II型,良恶性肿瘤血管分型比较,差异有统计学意义(χ2=12.437,P<0.05)。恶性肿瘤PSV明显高于良性肿块,RI明显低于良性肿块组,差异有统计学意义(t=3.285,2.974,P均<0.05)。结论经阴道超声结合多普勒超声检查对卵巢肿瘤良恶性判定有重要指导意义,适合在临床推广。
Objective To investigate the value of transvaginal ultrasonography combined with color Doppler ultrasonography in the diagnosis of benign and malignant ovarian tumors. Methods 60 cases of ovarian cancer patients treated in Mian-yin Hospital of Siping City, Jilin Province were selected as the research object. Forty-six benign and 14 malignant tumors were confirmed by pathology. Vaginal ultrasound and color Doppler ultrasonography were performed respectively. Morphological characteristics and distribution of blood flow in benign and malignant tumors were analyzed. The peak systolic velocity (PSV) and resistance index (RI) were measured. Tumor ultrasound score, to determine the tumor benign and malignant, and compared with the pathological diagnosis. SPSS 17.0 statistical software was used to process the data and the measurement data were expressed as (xˉ ± s). Seven tests were used to compare the data between groups. The data were expressed as a percentage of the two groups using χ2 test or Fisher exact test, P≤0.05 For the difference was statistically significant. Results The coincidence rate of ultrasound diagnosis of benign tumors was 93.8% (46/49), and the coincidence rate of malignant tumors was 78.6 (11/14). Doppler ultrasound showed that the blood vessels inside the malignant tumor were mostly distributed in the real region of the tumor, arranged disorderly and irregularly, and the blood flow type was mostly type Ⅲ. The benign tumor blood vessels were mostly distributed in the periphery or the interval, and the blood vessels were arranged regularly, sparsely, The subtypes were mostly type I and type II, and the difference was statistically significant (χ2 = 12.437, P <0.05). The PSV of malignant tumors was significantly higher than that of benign tumors, RI was significantly lower than that of benign tumors (t = 3.285, 2.974, P <0.05). Conclusion Transvaginal ultrasound combined with Doppler ultrasound examination of ovarian cancer benign and malignant has important guiding significance, suitable for clinical promotion.
