The clinical application of ultrasound and hysteroscopy in the diagnosis of endometrial polyps

Objective To evaluate the clinical application of ultrasound and hysteroscopy in the diagnosis of endometrial polyps.Methods A retrospective analysis of 76 cases diagnosed by the pathological diagnosis of endometrial polyps from 2003 to 2007 in our hospital was adopted,all of which were examined by transvaginal ultrasound examination and ultrasound intervention hysteroscopy before operation.The detection rate of endometrial polyps in these two methods was compared.The characteristics and misdiagnosis of these two ways were analyzed.The diagnostic value of ultrasound intervention hysteroscopy was estimated and explored.Results 76 cases were confirmed of endometrial polyps by pathology.The detection rate of which was 61.84%by transvaginal ultrasound,and 93.42%by ultrasound intervention hysteroscopy.The detection rate of the two methods are of significant different(P0.01).81.58%of transvaginal Ultrasonographic showed echo clumps high,while l8.42%showed low echo.22.37%showed blood flow at the bottom,while 77.63 showed no blood flow at the bottom.All the polyps in both cases had no blood flow signals inside.24 cases were misdiagnosed.Conclusion Polyps under the endoscopic ultrasound intervention hysteroscopy were oval or circular,bright red,smooth.Sometimes microvascular net could be seen and some polyps could be fluttered with the Palace of waves.Five cases were misdiagnosed.Conclusion vaginal ultrasound is non-invasive,simple and can be used as the preferred way to the census of endometrial polyps,but its missed rate is high.The accordance rate of endoscopic ultrasound intervention hysteroscopy is high,which is the gold standard of the diagnosis of endometrial polyps with pathological examination.If each of the patients was carried out the intervention hysteroscopy ultrasound,the success rate of operation can be improved.
