宫颈上皮内瘤样病变增生程度与阴道超声下宫颈强回声光斑的相关性研究

Study on correlation between proliferation degree of cervical intraepithelial neoplasia and cervical strong echo light spot under transvaginal ultrasonography

目的:探讨宫颈上皮内瘤样病变(CIN)增生程度与宫颈强回声光斑的相关性。方法:对收治的52例CIN患者行阴道彩色超声检查,对子宫及附件情况进行探查,重点对宫颈形态、大小、血流以及内部回声进行观察,比较CINⅠ～Ⅲ级强回声光斑的阳性率,分析CIN增生程度与宫颈强回声光斑的相关性。结果:CINⅢ级宫颈强回声光斑的阳性率显著高于CINⅠ级和CINⅡ级,差异有统计学意义(P<0.05);CIN的增生程度与超声检查发现的宫颈强回声光斑具有正相关关系(P=0.002);CINⅠ～Ⅲ级宫颈内血流计数不同,但是差异无统计学意义(P>0.05)。结论:宫颈上皮内瘤样病变增生程度与宫颈强回声光斑有明显的相关性,通过对该项指标的检测可以实现对早期宫颈癌及癌前病变的早期诊断。

Objective： To explore the correlation between proliferation degree of cervical intraepithelial neoplasia（CIN） and cervical strong echo light spot under transvaginal ultrasonography.Methods： Fifty-two CIN patients who were treated in the hospital underwent color Doppler transvaginal ultrasonography to explore uterine and adnexa uteri situations;the morphology,size,blood flow and inner echo were observed,the positive rates of strong echo light spot in patients with CINⅠ,CIN Ⅱ and CIN Ⅲ were compared,the correlation between proliferation degree of CIN and cervical strong echo light spot was analyzed.Results： The positive rate of cervical strong echo light spot in patients with CINⅢ was statistically significantly higher than those in patients with CINⅠ and CINⅡ（P 0.05）;there was a positive correlation between the proliferation degree of CIN and cervical strong echo light spot revealed by ultrasonography（P = 0.002）;the counts of blood flow in patients with CINⅠ,CIN Ⅱ and CIN Ⅲ were different,but there was no statistically significant difference（P 0.05）.Conclusion： There is a significantly positive correlation between the proliferation degree of CIN and cervical strong echo light spot,early diagnosis of early cervical cancer and cervical precancerous lesion can be achieved by detecting this index.
