目的:比较阴道B超与宫腔镜对子宫内膜息肉的诊断价值。方法:对108例因月经量增多、阴道异常出血就诊拟诊为子宫内膜息肉的患者分别行阴道B超及宫腔镜和(或)病理活检,比较两种方法对子宫内膜息肉的诊断准确性。结果:108例患者病理确诊为子宫内膜息肉者87例,占80.56%;阴道B超诊断为子宫内膜息肉者75例,3例误诊,15例漏诊,对子宫内膜息肉的诊断符合率、敏感性、特异性、假阴性率、假阳性率分别为83.33%(90/108)、82.76%(72/87)、85.71%(18/21)、17.24%(15/87)、14.29%(3/21),与病理检查结果比较差异具有统计学意义(P<0.05);宫腔镜诊断为子宫内膜息肉者87例,1例误诊,3例漏诊,对子宫内膜息肉的诊断符合率、敏感性、特异性、假阴性率、假阳性率分别为96.30%(104/108)、96.55%(84/87)、95.24%(20/21)、3.45%(3/87)、4.76%(1/21),与病理检查结果比较差异无统计学意义(P>0.05)。结论:宫腔镜较阴道B超对子宫内膜息肉的诊断符合率及敏感性、特异性更高,漏诊及误诊率低。
Objective: To compare the diagnostic value of vaginal ultrasound and hysteroscopy in endometrial polyps. Methods: A total of 108 cases of endometrial polyps diagnosed due to increased menstrual flow and abnormal vaginal bleeding underwent vaginal ultrasound and hysteroscopy and / or pathological biopsy. The diagnosis of endometrial polyps was compared between the two methods accuracy. Results: The pathological diagnosis of endometrial polyps in 108 cases were 87 cases (80.56%), 75 cases of endometrial polyps were diagnosed by vaginal ultrasonography, 3 cases were misdiagnosed and 15 cases were missed. The coincidence rate of diagnosis of endometrial polyps The sensitivity, specificity, false negative rate and false positive rate were 83.33% (90/108), 82.76% (72/87), 85.71% (18/21), 17.24% (15/87), 14.29% (P <0.05). There were 87 cases diagnosed as endometrial polyps by hysteroscopy, 1 case was misdiagnosed and 3 cases missed diagnosis. The diagnosis of endometrial polyps The coincidence rate, sensitivity, specificity, false negative rate and false positive rate were 96.30% (104/108), 96.55% (84/87), 95.24% (20/21), 3.45% (3/87) 4.76% (1/21), no significant difference with the pathological findings (P> 0.05). Conclusions: The diagnostic accuracy and sensitivity of hysteroscopy versus vaginal ultrasound in endometrial polyps are higher, the specificity is higher, the rate of missed diagnosis and misdiagnosis is lower.
