Accuracy and causes of missed diagnosis and misdiagnosis of transvaginal color Doppler ultrasound in differentiating endometrial polyps and endometrial cancer
[Objective]To explore the accuracy and causes of missed diagnosis and misdiagnosis of differentiating endometrial polyps and endometrial cancer by transvaginal color Doppler ultrasound.[Methods]The clinical data of 100 patients with endometrial lesions(65 patients with endometrial polyps and 35 patients with endometrial cancer)admitted to Jiyuan Second People's Hospital were retrospectively selected as the research object,and the selection time was from January 2021 to December 2022.All patients were examined by transvaginal color Doppler ultrasound and pathological examination,and the pathological results were the gold standard.The detection results and diagnostic efficacy of transvaginal color Doppler ultrasound in differentiating endometrial polyps and endometrial cancer were counted,and the ultrasonic manifestations and related parameters of endometrial polyps and endometrial cancer were compared.[Results]A hundred cases of endometrial lesions were diagnosed by transvaginal color Doppler ultrasound,34 cases were positive and 66 cases were negative,of which 63 cases were real endometrial polyps and 32 cases were endometrial cancer,2 cases were misdiagnosed and 3 cases were missed.Its specificity was 96.92％(63/65),sensitivity was 91.43％(32/35),accuracy was 95.00％(95/100),positive predictive value was 94.12％(32/34)and negative predictive value was 95.45％(63/66).The proportion of patients with unclear decomposition of endometrium and myometrium and uneven internal echo,blood flow classification and endometrial thickness of the endometrial cancer group were higher than those of the endometrial polyp group.The levels of resistance index(RI),pulsatility index(PI)and average blood flow velocity(TAP)of the endometrial cancer group were significantly lower than those of the endometrial polyp group(P＜0.05).[Conclusion]In differentiating endometrial polyps and endometrial cancer,transvaginal color Doppler ultrasound examination has a higher diagnostic efficiency,and there are differences in ultrasonic manifestations and related parameters,which has a higher diagnostic advantage.Therefore,the results of transvaginal color Doppler ultrasound examination,its imaging characteristics and related parameter evaluation can be used to evaluate endometrial polyps and endometrial cancer in clinic.
