[摘要]目的 探討經(jīng)陰道能量多普勒超聲診斷在宮頸癌前病變中的應(yīng)用價(jià)值。方法 根據(jù)隨機(jī)抽樣法選取2016年4月～2018年4月在我院就診的52例疑似宮頸癌前病變的女性患者作為觀察組，選取同期在我院體檢的女性健康體檢者52例，作為對(duì)照組。兩組均采用超聲診斷，觀察組之后進(jìn)行陰道鏡病理切片檢查確診。對(duì)比超聲診斷和陰道鏡的病理診斷結(jié)果，評(píng)估經(jīng)陰道能量多普勒超聲診斷宮頸癌前病變的應(yīng)用價(jià)值。結(jié)果 在陰道鏡病理診斷結(jié)果中，癌前病變25例，早期宮頸癌24例，宮頸炎癥2例，宮頸肌瘤1例；在超聲診斷結(jié)果中，癌前病變27例，早期宮頸癌25例。超聲診斷的符合率為94.23%，誤診率為5.76%。與健康對(duì)照組女性相比，觀察組患者的宮內(nèi)血流信號(hào)顯著增多。觀察組患者的阻力指數(shù)（RI）指數(shù)（0.50±0.14）顯著低于對(duì)照組（0.71±0.05），其脈收縮期峰值血流速度（PSV）[（10.68±6.85）cm/s]明顯高于對(duì)照組[（8.50±4.47）cm/s]，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。觀察組患者的血流信號(hào)分級(jí)情況優(yōu)于對(duì)照組，差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。結(jié)論 經(jīng)陰道能量多普勒超聲應(yīng)用于宮頸癌前病變的診斷中，具有較高的診斷準(zhǔn)確率，可清晰、客觀地顯示子宮內(nèi)局部病變血流的分布情況，可作為臨床診斷宮頸癌前病變的重要輔助檢查手段。

[Abstract] Objective To investigate the diagnostic value of transvaginal power Doppler ultrasound in cervical precancerous lesions. Methods A total of 52 female patients with suspected cervical precancerous lesions from April 2016 to April 2018 were selected by random sampling as the study group， and 52 female healthy examinees in our hospital during the same period were selected as control group. The two groups were diagnosed by ultrasound， and the observation group was diagnosed by colposcopy biopsy. The value of transvaginal power Doppler ultrasonography in the diagnosis of cervical precancerous lesions were evaluated by comparing the results of ultrasonography and colposcopy pathology. Results Among the results of colposcopic pathological diagnosis， 25 cases were precancerous lesions， 24 cases were early cervical cancer， 2 cases were cervical inflammation and 1 case was cervical myoma. Among the results of ultrasound diagnosis， 27 cases were precancerous lesions， 25 cases were early cervical cancer， the coincidence rate of ultrasound diagnosis was 94.23%， and the misdiagnosis rate was 5.76%. Compared with healthy controls， intrauterine blood flow signals in the observation group increased significantly. The resistance index （RI） of the observation group （0.50±0.14） was significantly lower than that of the control group （0.71±0.05）， the peak systolic blood flow velocity （PSV） of the observation group （[10.68±6.85] cm/s） was significantly higher than that of the control group （[8.50±4.47] cm/s）， with statistical significance （P<0.05）. The grading of blood flow signals in the observation group was better than that in the control group， with statistical significance （P<0.05）. Conclusion Transvaginal power Doppler ultrasound has a high diagnostic accuracy in the diagnosis of cervical precancerous lesions. It can clearly and objectively display the blood flow distribution of local lesions in uterus， and can be used as an important auxiliary means for clinical diagnosis of cervical precancerous lesions.
