摘　　要：目的:探讨高频超声在乳腺导管疾病中的检出率及误诊影响多因素logistic回归分析。方法:选择2019年5月-2021年12月萍乡市人民医院收治的100例疑似乳腺导管疾病患者,所有患者入院后均行高频超声检查,以病理检查结果作为“金标准”,计算高频超声在乳腺导管疾病中的检出率及误诊率。查阅患者病历资料及超声征象,对误诊患者可能的影响因素进行logistic回归分析。结果:高频超声检查最终确诊67例,与金标准诊断符合率为71.00%。诊断敏感度为77.14%,特异度为56.67%;阳性预测值为80.60%、阴性预测值51.52%,误诊率为43.33%。多因素logistic回归分析结果显示,内部回声均匀、增强范围不扩大、增强后病灶边缘光滑是高频超声诊断乳腺导管疾病患者误诊的危险因素,搏动指数(PI)、阻力指数(RI)是高频超声诊断乳腺导管疾病患者误诊的保护因素(P<0.05)。结论:高频超声用于乳腺导管疾病患者中能获得较高检出率,但是亦具有一定的误诊病例,其受到的影响因素较多,应根据可能的影响因素采取相应的干预措施,提高患者检出率。Objective:To investigate the multivariate logistic regression analysis of the detection rate and misdiagnosis of high-frequency ultrasound in breast duct diseases.Method:A total of 100 patients with suspected breast duct disease admitted to People’s Hospital of Pingxiang City from May 2019 to December 2021 were selected,all patients underwent high-frequency ultrasound examination after admission,and the detection rate and misdiagnosis rate of high-frequency ultrasound in breast duct disease were calculated,used pathological examination results as the“gold standard”.The patients’medical records and ultrasound signs were consulted,and the possible influencing factors of misdiagnosed patients were analyzed by logistic regression.Result:A total of 67 cases were confirmed by high frequency ultrasonography,and the coincidence rate with gold standard diagnosis was 71.00%.The diagnostic sensitivity and specificity were 77.14%and 56.67%.The positive predictive value was 80.60%,the negative predictive value was 51.52%,and the misdiagnosis rate was 43.33%.Multivariate logistic regression analysis showed that homogeneity of internal echo,no expansion of enhancement range and smooth edge of lesion after enhancement were risk factors for misdiagnosis of breast duct disease by high-frequency ultrasound,and pulse index(PI)and resistance index(RI)were protective factors for misdiagnosis of breast duct disease by high-frequency ultrasound(P<0.05).Conclusion:High-frequency ultrasound can achieve a high detection rate in patients with breast duct disease,but there are also some misdiagnosed cases,which are affected by many factors corresponding intervention measures should be taken according to the possible influencing factors to improve the detection rate of patients.
