经阴道超声用于术前诊断原发性卵巢癌盆底腹膜转移的可行性分析

Feasibility of Transvaginal Ultrasound in the Diagnosis of Peritoneal Metastasis of Primary Ovarian Cancer

目的探讨经阴道超声用于术前诊断原发性卵巢癌盆底腹膜转移的可行性。方法收集术前经阴道超声检查的原发性卵巢癌患者36例。观察卵巢、盆底腹膜及盆腔积液的情况,并与手术过程中所见情况进行比较。结果 36例卵巢癌患者术中诊断发生腹膜转移22例,阴道超声诊断确诊19例,阴道超声对卵巢癌诊断的灵敏度、特异度以及准确率分别为73.1%、80.0%和75.0%。36例卵巢癌患者发生盆腔积液患者22例,其中超声诊断阳性19例,超声诊断阴性17例,超声诊断盆腔积液灵敏度为89.5%(17/19),特异度为70.6%(12/17),盆腔积液有无对盆底腹膜改变诊断价值具统计学意义(P<0.05)。结论经阴道超声对原发性卵巢癌盆底腹膜转移有较高的诊断价值。

Objective To study the feasibility of transvaginal ultrasound in the diagnosis of primary ovarian cancer and of pelvic peritoneal metastasis .Methods 36 primary ovarian cancer patients were selected .All the patients underwent transvagi-nal ultrasonography before surgery .Ovary,pelvic peritoneal and pelvic effusion were observed ,and compared with the situation ob-served during surgery .Results In 36 cases of ovarian cancer ,there had 22 cases of peritoneal metastasis ,19 cases of vaginal ul-trasound diagnosis .Transvaginal sonography in the diagnosis of ovarian cancer , the sensitivity , specificity and accuracy were 73.1%,80.0%and 75.0%.In 36 cases of ovarian cancer ,ultrasound diagnosis of 19 cases were positive,17 were negative.Ul-trasonic diagnosis of pelvic effusion with a sensitivity of 89.5%（17/19）,the specificity was 70.6%（12/17）.Pelvic effusion had no diagnostic value of pelvic peritoneum was statistically significant （P〈0.05）.Conclusion Transvaginal ultrasound in primary ovarian cancer has a high diagnostic value of pelvic peritoneal metastasis .
